Vegetarianism is a "health-preserving" diet in many people’s minds. In recent years, many people have joined the ranks of vegetarians. At present, the number of vegetarians in China is about 50 million, and "vegetarianism" is becoming popular.

Although more and more people are vegetarian, unreasonable diet is a problem. Long-term unreasonable vegetarian diet can not only make the body healthier, but also lead to malnutrition.

What kind of influence will vegetarianism have on the body, and what is the correct way to open vegetarianism? In this article, we will answer the questions about vegetarianism, and attach an egg white recipe at the end of the article, so you can keep it for reference!

What are the benefits of vegetarianism?

Vegetarian food with reasonable diet can not only provide adequate nutrition for the body, but also reduce the risk of many diseases. Studies have shown that the mortality of all-cause mortality’s disease, ischemic heart disease, circulatory system disease and cerebrovascular disease in vegetarian population is significantly lower than that in omnivorous population with animal food. [1] Moreover, the risk of hypertension, type 2 diabetes and cancer in vegetarian population is lower than that in animal omnivorous food population.

Which two vegetarian dishes are more recommended?

The most common vegetarianism can be roughly divided into two types: ovalbumin and vegan. Egg-lactating people can also eat eggs and milk food besides vegetarian food; Vegan is a strict vegetarian, and does not eat any animal food, including eggs and milk. No matter what kind of vegetarian diet, as long as it can ensure a balanced nutrition. However, compared with the two, vegan has more disadvantages. If you must be vegetarian, you should recommend egg white.

What nutrition is vegetarian easy to lack?

For vegetarians, there is no serious shortage of carbohydrates, fats, dietary fiber and water for vegetarians, and it is easy to meet their physical needs as long as they follow the requirements of Dietary Guidelines for China Residents. Emphasis should be placed on preventing the deficiency of protein, vitamin B12, mineral iron and zinc, because meat food is an important source of high-quality protein, vitamin B12 and mineral iron and zinc. Therefore, we should pay attention to the intake of these nutrients in the diet, and we also need to pay attention to the supplement of vitamin D.

How to supplement the nutrition that is easy to lack?

(1) protein:

Although the protein of meat is high-quality protein, it is not only meat that contains protein. Eggs, milk and beans are all sources of high-quality protein.

The people who eat egg yolk are advised to eat every day:

A whole egg

300~500ml milk

25g soybean or corresponding amount of bean products (50g dried bean curd or 50g shredded bean curd or 100g north bean curd).

15~25g nuts (vegan 20~30g)

All kinds of miscellaneous grains and beans

In this way, the intake of protein is at least 50g/d, which is more than 90% of the recommended daily intake of 55g for women in protein. If it is male, it is recommended to add 10~20g protein powder on this basis every day. It should also be noted that different kinds of protein foods should be eaten at the same meal as far as possible, which can play a complementary role in protein and improve the absorption and utilization rate of protein. [1] For example, protein, a cereal food, lacks lysine and is rich in methionine, while protein, a legume food, lacks methionine and is rich in lysine. When they are eaten together, the proteins can complement each other.

② Vitamin B12: Vitamin B12 mainly exists in animal foods, and it is a nutrient that is easily overlooked by everyone. Serious lack of vitamin B12 will cause nerve fiber degeneration, symptoms such as listlessness, anxiety, forgetfulness, and even anemia, so vitamin B12 is also called "nutritional nerve" vitamin. A survey shows that vitamin B12 deficiency is common in vegetarians with elevated homocysteine level and enlarged red blood cells, especially in vegetarians. [2] Vitamin B12 mainly exists in meat food, which is easy to be deficient for vegetarians.

Plant foods rarely contain vitamin B12, and fermented bean products such as fermented soybean meal, fermented bean curd, natto, seaweed and mushroom have some, but the salt content of fermented soybean meal and fermented bean curd is generally high, and the taste of natto is unacceptable to many people. Therefore, it is difficult to make up enough by diet, so it is recommended to take vitamin B12 supplements. ③ Mineral iron: Animal foods such as red meat, animal blood, animal liver and shellfish are good sources of iron supplement, and the iron contained is heme iron, which is easy to be absorbed and utilized by human body.

However, plant foods such as auricularia auricula, Tricholoma matsutake, red dates, spinach, moss, etc., although high in iron content, belong to non-heme iron, and the absorption and utilization rate of human body is low. However, if it is combined with vitamin C, it can help to improve the absorption and utilization rate of iron in plant foods [1]. Therefore, it is suggested that vegetarians should add fruits and vegetables rich in vitamin C in their diet, such as Chinese cabbage, kiwi fruit, winter jujube, blood orange, guava, etc., and supplement Vc tablets or iron.

④ Mineral zinc: In addition to meat, nuts, coarse grains and fermented bean products are also good sources of mineral zinc, such as sunflower seeds, pine nuts, pumpkin seeds, chestnuts, black sesame seeds, etc. Among them, phytic acid in bean products is destroyed after fermentation, and the absorption and utilization rate of zinc will also increase.

One day, the egg custard recipe came!

According to the dietary recommendations for vegetarian people in the Dietary Guide for China Residents, people with egg yolk can refer to the following recipes (light-bodied women who do not need to lose weight) to arrange their diet for one day:

If it is a male, the ingredients that need to be adjusted are: 50 grams of millet, 100 grams of sweet potato, 20 grams of walnut, 40 grams of red dates, 80 grams of white flour and 100 grams of tofu.

Note: ① The amount of salt is not written in the recipe, so everyone should control it by themselves. It should not exceed 6 grams of salt every day, which is less than 1 bottle cap of mineral water (1~2 mm short of the bottle cap).

6 grams of salt (Master Kong packaged drinking water bottle cap) 2 The cooking pot is best to be non-stick, otherwise it will cost more oil.

A porcelain spoon is about 10 grams of oil.

Remarks:

Vegetarian people are easy to lack vitamin B12 and mineral iron, so it is recommended to supplement multivitamins or targeted supplements every other day; In order to promote the absorption of calcium, it is recommended to supplement 10 micrograms of vitamin D every day.

Vegetarian people are easy to lack n-3 polyunsaturated fatty acids, so it is suggested that rapeseed oil and soybean oil should be used more in cooking, and linseed oil and perilla seed oil should be used more in cold salad.

Illustration of some ingredients:

Three red dates (20 grams of edible part) Want to know the weight of jujube stones? I eat very clean!

2 grams of laver

30 grams of carrots

20 grams of red beans (mung beans for reference)

100g sweet potato

10 grams of paper walnut Although this recipe is only for one day, as long as you change the ingredients carefully, you can change the recipe for many days. For example, change Chinese cabbage into rape, green pepper into colored pepper, dried tofu into dried tofu, garlic sprout into leek, sweet potato into purple potato, walnut into cashew nut and so on.

Focus

For friends who like vegetarianism, vegetarianism is also ok. However, ovalbumin is easier to achieve nutritional balance than vegan, and it is more recommended.

In addition, when you are vegetarian, you must mix it reasonably, and pay attention to supplementing compound nutrients or specific nutritional supplements.

Introduction:

On August 24th, the latest issue of Horizon’s "Hello, Developer" Autopilot Technology Special Session was successfully broadcast in the Zhidong Open Class.

The special session was given by Dr. algorithm engineer Zhu Hongmei, Horizon Perception, with the theme of BEV Perception Scheme and Deployment Practice Based on Journey 5. This article is a record of the lecture session of this special session. If you need live playback and Q&A, you can click

Good evening, friends of the open class of Zhidong. I’m Perception algorithm engineer Zhu Hongmei from the horizon, and I’m honored to share with you today "Ji"BEV awareness scheme and deployment practice in Journey 5》。 I will introduce it from five aspects.

01

General introduction of BEV perception framework

With the release of Journey 5 in 2021, we designed the sensing prototype scheme of BEV based on Journey 5. The input is vehicle-mounted multi-angle image sequence or multi-mode signal, and the fusion of time and space dimensions is carried out within the network, so that the neural network can output the dynamic and static sensing and prediction results from a bird’s-eye view.

Below is a frame diagram.

The green background part represents the signal processing of pure vision, and the input is the images of each camera. After the first stage of model extraction, the image features are transformed into multi-view spatial fusion from BEV perspective. Then, the features of BEV are fused in time sequence, and then sent to the second stage for feature extraction on BEV; Finally, input it to the head part for the output of perceptual elements. If there is a Lidar in the system, it will also be connected to the Lidar point cloud. In the early stage, we will do rasterization coding processing, and we will also do time sequence fusion. Finally, we will do intermediate fusion with visual BEV features, and also send them to the second stage to output the perceptual elements on BEV.

The blue part is the closed-loop iteration that has participated in many rounds. Students who pay attention to the horizon should know that at the Shanghai Auto Show in April this year, this part of the content has supported the closed-loop demo display of real cars. In recent six months, we have expanded the function of "dynamic obstacle detection" in sensing elements. Based on it, we connected the head of Transformer to do the Track id, speed estimation and trajectory prediction of dynamic obstacles. The dotted line part is currently under development, and we also want to make full use of the dynamic and static sensing results on BEV to output the interactive elements of dynamic and static sensing, such as behavior prediction.

There are two main modes of pure vision scheme here. One is the 11v integration scheme for double Journey 5; The other is a single journey chip-oriented scheme, in which 7v for driving and 5v for parking are integrated. Today’s sharing mainly focuses on the integration of time and space in the visual scheme, the analysis of perceptual elements, and the introduction of dynamic, especially dynamic perceptual prediction end-to-end scheme and deployment.

02

Spatio-temporal fusion module and chip deployment

Firstly, it is introduced that the four-plane space fusion method is adopted at the end of the plate at present. It takes the xy plane of the self-propelled coordinate system as the basic plane, and adds three height planes on this basis, hoping to obtain more scene image information with different heights. Time series fusion is relatively simple. We will cache the features after time series fusion at the last moment, align the historical frames to the current frame by using the self-driving motion between frames, and fuse them with the spatial fusion features of the current frame, and then deconvolution them and send them to the following network structure for perceptual output.

So why do we use this scheme?

In the early stage of research and development, we also compared different spatial fusion methods. In the early stage, in order to quickly get through the process, we adopted the simplest method based on single plane IPM to get through the perception of the whole framework. After that, I went to find out the depth-based fusion and transformer-based fusion scheme on Journey 5. The assessment dimension is the delay in Journey 5, assuming that the prerequisite is to be able to independently run this model above 30fps on the single core of Journey 5 to design the corresponding network parameters.

There are two key parameters that affect the perceptual performance of BEV, one is the resolution of image feature in one stage, and the other is the fusion resolution on BEV. The fusion resolution on BEV is relatively direct, and the higher the resolution, the better the perception of some small targets and point elements. Image resolution determines the amount of information input in two stages.

Here is a lane line simulation diagram, and the physical dimensions of each lane line are the same. Because it is perspective projection, the farther the lane line is in the image, the fewer pixels it will have. BEV indexing image features is generally a process of reverse realization, while BEV is generally designed with equal resolution, such as 0.6 and 0.4 m Grid resolution. When the distant objects in the scene are indexed by the coordinates of BEV, the physical resolution of the pixels in the image is already lower than that on BEV, and at this time, feature duplication will appear on BEV, which is a common stretching phenomenon. Reflected in the perception, for example, the detection box may have the phenomenon that the target splits into a string, so the feature resolution in one stage is also very important.

We grab the middle column of pixels to simulate the contrast of Z-value changes between two adjacent rows of pixels in 2M image and 8M image at 50m. It can be seen that the physical range of the low-resolution image corresponding to two adjacent rows of pixels has changed by more than 2 meters. For a high-resolution image, its adjacent two pixels are only about 0.6 meters. Therefore, when looking at the fusion scheme, we should not only consider whether a single task meets certain accuracy requirements, but also consider the final deployment, because it is multi-task and different perceptual elements output, so we hope that the resolution of one-stage feature and BEV fusion can be higher.

From this point of view, the current structure based on Transformer can meet the requirements of Journey 5, single core and 30+FPS, and the first-stage resolution and the second-stage fusion resolution are relatively low, and the delay is too high under this condition. However, the depth-based fusion method is lower than single plane in one stage. In addition, one reason for not adopting it is that the depth-based deployment has made some specific improvements for Journey 5, reaching a two-phase delay of 9.6 ms. In the stage of prototype verification, the flexibility of carrying different numbers of cameras on the car is not enough, so we adopt the plane mapping fusion method at this stage. In the early stage, we used a single plane, but when we actually did the closed-loop verification, we found that the generality and robustness of camera parameters were not enough, and it was sensitive. Therefore, we improved it in the further research and development process. Through various tests and verifications, we finally adopted the four-plane fusion method, which can achieve a good balance between performance and delay.

For time series fusion, different time series fusion methods will also be compared in the early stage of research and development. The basic method is to align the historical BEV features to the current frame and use different fusion methods to do time series fusion. Here is also a comparison of the fusion of different frames, with the experimental data accumulated at that time to do 10 frames of verification. In the case of 10 frames, there is an improvement of 3.5 points compared with only space. For latency, it is only increased by 1ms because it is deployed in recurrent mode.

Similarly, we also compare the two methods of obtaining historical frames. One is to intercept historical information at equal time intervals, and the other is at equal space intervals. Equal time interval is to use the system timestamp to index and read the corresponding frame. Equal space interval is to calculate the translation distance with the movement of the vehicle, and then get the frame. Finally, we found that the performance of equal space interval of 6 frames is similar to that of equal time interval of 10 frames, and they can also be combined, but the improvement of more fused frames is not great. Therefore, in order to simplify the deployment, we currently adopt the time series fusion method with equal time intervals.

There may be some differences in the training and deployment of time series fusion. One is the Odometry used when aligning two adjacent frames. In order to make the training model performance consistent with the real vehicle deployment, one principle to be observed is that the model input should be consistent with the board signal as much as possible. We use Odometry of wheel speedometer to do model training, and do tests on Odometry obtained by different methods. It is found that if it is consistent with the inter-frame interval during training, then this factor has little influence. In addition, for example, historical frames are obtained at 100ms intervals, and the model trained with 10fps training data is tested at 10fps, 15fps and 30fps. The conclusion is that if there is a big difference between deployment and training, the index gap will be even bigger. The actual system frame rate is affected by the real-time load of the system, and it may not be completely aligned no matter how to set the inter-frame interval during training. Generally, the perimeter perception can be around 15fps, which can basically meet the functional requirements, and the range of 1.5 points is also acceptable. This part can also make the distribution of time series training data more abundant through some data enhancement methods, and alleviate such problems.

The other is that when the time series is being trained, if there is no specific optimization, with the increase of the number of frames, some OOM(Out of Memorry) problems may occur in the time series data, which leads to the slow training speed. The training method is to adopt the feature cache strategy to alleviate or avoid such problems. However, when deploying on the board side, considering the memory limitation of the board side and the bandwidth loaded back, the most streamlined strategy recurrent mode is finally adopted on the board.

Analysis of static and Occupancy perception elements

An important component of static perception is truth value. How did the truth value on BEV come from?

From the very beginning of research and development to the present, three static truth values have been used. At first, high-precision maps were used, and now the truth production link based on multi-mode is used on a large scale. At present, the local mapping results of pure vision are also involved in the training. The quality of the drawings is developed by our company’s special 4D-Label team. At the special session of horizon "Hello, developer" autopilot technology, Dr. Sui Wei, the head of horizon 4D labeling technology, also shared the "4D labeling scheme for BEV perception". If you are interested, you can review it.

For the algorithm, the algorithm students should be more involved in the formulation of labeling rules. Even if the truth value is brushed by the big model, the big model needs the truth value, so the labeling rules need the deep participation of the students of the perceptual algorithm, especially the actual test scenario is very complicated. A reference condition of labeling rules is the Lidar point cloud base map obtained by mapping, which is an intensity map on BEV, and then it can be labeled by referring to images or videos. For example, lane lines should be marked with colors, some functional attributes and some downstream functions that are necessary and cannot be obtained from the Lidar bottom map, all of which need to be combined with images. For pavement signs, they are usually unmarked rotating frames, and for those that need a clear direction, they need to be marked in an orderly sequence. The elements of parking are basically to mark parking spaces, wheel gears, speed bumps and so on by marking key points.

The output of the model corresponds to the annotation. The marked information will be preprocessed to generate the true value of the model. Only when the truth value is supervised output can the downstream functional requirements be met. The lane line output is the position and attribute of the example point column; The intersection point is the position and type of the point; Curbside is also the instance position and type; Pavement discrete signs are detection frames and types. These static perception elements are very rich. For the model scheme, there is a classification learning of foreground extraction, a regression learning of accurate position, and a learning of example features of lane lines. On the whole, the static perception scheme is relatively conventional. When analyzing, line elements such as lane lines will extract the foreground through the score of Class Map, then cluster the points through the Embedding similarity, and reverse the attribute features to index the corresponding features of these points.

For lane lines, in the actual software analysis, we should consider the delay on the software, roughly estimate the direction of lane lines through vertical points according to the preset, and do one-dimensional search along this direction to shorten the post-processing time of lane lines. Now our scheme is newly optimized, and it takes less than 3ms to deal with this part. The analysis of pavement signs, detection points or boxes at intersections is a set of CenterNet: card score→maxpolling→TopK→ attribute extraction → output.

For parking elements, parking spaces will output orderly corner position, occupancy and parking space type direction; The wheel stopper is an orderly end position and type; The underground locks and columns under the parking lot are all output by detection frames, which are the same as the analytical ideas of the previous points and line frames. The parking space here has two small head, one of which is to obtain the overall attributes of the parking space, such as its occupancy, and whether the parking space type is parallel or vertical. There is also a Local head to accurately estimate the corner of the location, because the accuracy of this corner of the location is very high. After getting a more accurate one, calculate the point matching with the rough corner position obtained under global. Because this point is orderly, you can just card a distance threshold. After matching, you can get an accurate corner coordinate by replacing the corner coordinate.

This is our performance. The 2D perception scheme of horizon has been polished for a long time before, which is equivalent to having a good reference baseline for BEV perception.

Compared with the 2D scheme, lane lines and road signs have a great improvement in ranging, such as lane lines in different distance sections, arrows and stop lines of road signs. For parking spaces, Horizon also has a pre-fusion scheme. Before being sent to the network, four fish-eye images are fused by IPM to get an IPM image covering 360 degrees around the car, and then integrated into the network to output parking spaces. Now BEV is introduced in the previous framework, and feature are fused inside the model. At present, there are also great improvements in these three class libraries.

Take a look at this video, which is a visual display of a high-speed lane line, with a wide dotted line, and then get off the ramp. Here is a diversion point, a change point between reality and reality, and the arrow represents the direction.

For the perception of parking space, a parking scene is chosen here, where the red line represents the entrance line, the yellow X represents the occupation, the yellow box is the pillar of the parking lot, and the grass green is the wheel stopper.

Let’s talk about the perception of Occupancy. First of all, Occupancy is a 2D occupancy graph based on Journey 5, which is a binary graph, where 0 means unoccupied and 1 means occupied. We call it Freespace internally. The traditional Freespace is image segmentation and post-processing to calculate the drivable area under BEV. It is more natural to do it on BEV, and output such a binary image directly on BEV. Its true value depends on Lidar segmentation model+detection model+threshold of cloud card height of multi-frame aggregation point to obtain some obstacles on the ground. Lidarseg mainly obtains the basic surface first, and takes the road plane as the drivable area; Lidar3D detection is to supplement the true value of dynamic obstacles in the white list.

The other output is Vismask. It mainly describes the area that the vehicle can see in the image at the current moment, and also uses Lidarseg model and 3D detection model. Image segmentation combined with back projection of point cloud can get the points that can be seen under BEV, calculate the ray according to the semantics and camera parameters, and then calculate the surface paved by the points that can be seen in the image in the self-propelled coordinate system, and then flatten them in the height direction of point cloud to get the visible Grid points on BEV. Why do you need 3D detection? Because when the ray hits the point cloud, it is a surface. We want the whole object of the surface boundary to be visible, so we need a 3D detection frame to supplement the object of the boundary, thus obtaining the true values of these two tasks. Perception model is a relatively simple binary classification model. Vismask’s 0 means invisible and 1 means visible.

Because these two tasks are dense outputs, when actually doing this on the board, its bandwidth occupation is relatively large. Usually, we will use a Run Length Encoding (RLE) to compress the result. For example, Freespace, as shown in the following figure, has the same values in a connected region. Run-length coding is used to reduce the bandwidth of the perceptual results transmitted from BPU of Journey 5 to CPU, and a final output binary image can be obtained by doing a back analysis in CPU.

Here is a visual video, and the bar on the left is a response to the fence. This is a specially built evaluation set, including strollers, fallen cones and so on. Here, Freespace is mainly to supplement the perception of non-standard obstacles. In addition, it is also useful to feed back the representation of roadside by Freespace when the downstream closed loop is used.

04

Dynamic Perception Predicting End-to-End and Chip Deployment

Let’s introduce the end-to-end scheme of dynamic sensing prediction and chip deployment.

The end-to-end model, as shown in the previous frame, is followed BEV3D several layers of Transformer decoder to output dynamic end-to-end elements. The multi-scale features extracted by BEV in two stages are reused, and there is a detection head of BEV3D, which regresses to the heatmap and the offset to the precise position to get the possible target position.

For Transformer head, it depends on how the Q/K/V of its input comes from the first layer. There is a construction part of the input. First of all, "q" is divided into detection query and Track query. Detect the position embedding； of query, which is the position parsed from BEV3D head and obtained by MLP; Context embedding is learnable and can be initialized randomly.

For the position embedding of Track query, the position of the previous frame will be used, and the self-vehicle motion between frames will be aligned to the current frame to eliminate the self-vehicle motion. Then, the position of the current frame is estimated by combining the speed estimation result of the previous frame itself, and the position embedding of Track query is obtained by MLP. Its context embedding was also randomly initialized and learnable at the beginning, which resulted in "Q".

"K" and "V" For BEV, there is a fixed mapping relationship between the pixel coordinates on BEV and the coordinate positions under VCS. Therefore, according to the position of the reference point, its pixel coordinates on multiple dimensions of BEV can be calculated reversely. Query also sorts from 0 to N-1, and it has an index, so that the difference between the two coordinates can be calculated into the mapping relationship between them. Then the warping operator, that is, the grid_sample operator, is used to reversely index the BEV region features, and then "K" and "V" are generated through MLP, so that the end-to-end head input is constructed.

One of the differences in Transformer here is that it improves the quantization and efficiency on Journey 5, and removes the MatMul matrix multiplication operator. Here, the commonly used Deformable attention is replaced by warping.

The output layer of end-to-end head is actually several MLPs. Among them, the output of trajectory and speed will pass through Memory bank in order to obtain historical information. The point of the trajectory output here is also the displacement between frames, and the velocity describes the position change of unit time between frames in the future. We think that these changes are not abrupt, but smooth, so we use historical information.

The embedding of history is composed of two parts. The first part is the Oddity of N historical frames and the embedding of query output by Transformer decoder of N historical frames will be stored in Memory bank. Query of the current frame, and pay attention to the time sequence of the current frame and the historical frame for each target. After that, self-attention will also be done among the targets, and finally we define it as Temporal embedding. In addition, speed embedding is added. How did it come from? That is, the position of historical frame N is transferred to the current frame through the odometry of the vehicle motion, and the position of the historical frame under the current frame is obtained, so as to eliminate the vehicle motion and obtain the inter-frame offset. Combining with the frame rate of the system, a time difference can be derived, and the historical inter-frame speed can be estimated. Similarly, after passing an MLP, the embedding of the speed can be obtained. By making a simple concat, the final historical embedding can be obtained and input to the trajectory.

After the model is output, some of it will be analyzed in CPU. For Track query and Detect query, the model output itself will analyze the position, length, width, height, orientation angle, Score confidence and so on. The function of track management is to screen out the Track query of the next frame. Two thresholds are set here. A higher threshold is to filter out the tracked query with higher confidence from all the queries, that is, the tracked query, and identify the newly generated target in the current frame. For the newly generated target, a current maximum id value of +1 is given, and its disappearance time is initialized to 0. For setting a low threshold, I want to recall those targets that have been tracked before, but have low confidence in the current frame due to occlusion and other reasons. If it can be greater than this threshold, and the disappearance time is not greater than the set time, it will continue to be preserved. If the time of disappearance (disp_times) has been greater than the threshold of the number of frames that can be dropped, we will definitely drop this target in this frame.

For the analysis of velocity, the model itself can be directly output, and kinematics post-processing will be added after it comes out. The "z" here is the length, width, height and speed (attribute) of the previous output, which we call observation. The model will also learn from the gain matrix of Kalman, avoiding calculating "k" on CPU, and finally giving the filtered state quantity to the downstream. Compared with the unfiltered operation, this operation has a 19% improvement in speed accuracy. From the visual performance, the speed does appear smoother after this. When updating the embedding of Track query in the next frame, the historical embedding generated in Memory bank will be used. The details of QIM will not be expanded, so you can refer to the implementation of MOTR.

Take a closer look at the performance of the end-to-end model. End-to-end comparison is only detection, tracking and speed estimation through post-processing. The baseline detection compared here is already 3D detection on BEV. Compared with the original 2D detection, it has obvious advantages in ranging. Blue and green are the vertical error percentages of 2D detection in different distance segments, and red and purple are BEV3D. It can be seen that the end-to-end model is more advantageous than BEV3D on the basis of this better baseline.

First of all, take a look at ranging and speed measurement. From end to end, ranging and velocity measurement have obvious advantages on three kinds of dynamic obstacles. The lower the error here, the better, and here is the percentage of error reduction, especially the speed advantage is particularly obvious. Trajectory comparison is a cascade model, its input is the dynamic post-processing of 3D detection on BEV, and some vector information of lane line static post-processing after environmental reconstruction, which is a separate trajectory prediction model. The end-to-end input is the image, and the direct output is the trajectory. Compared with the two, end-to-end has obvious advantages in the position error of this point series.

Here is also a visual video. The box in the picture is the target, the yellow line represents the horizontal and vertical speed, and the pink line is the trajectory. It can be seen that the target coming from the right can appear stably when it passes in front, although it is blocked by the target here. For the speed advantage mentioned just now, especially for the target parked next to it, if it is a detection frame, once the jitter is beyond the range of post-processing energy cover, there will be a relatively large speed, which will trigger a trajectory and cause some brakes of the car. Like here, parked next to it is very stable, and the speed is basically consistent with reality.

05

Real vehicle deployment and closed-loop verification

The last part introduces several key problems related to the model when the real vehicle is closed-loop.

First of all, the model must be quantified and compiled before deployment. Professional quantitative processes and methods, we also arranged an open class to share later. I mainly look at this matter from the perspective of a user.

For the general model, such as CNN-based, we directly single-task float and directly train qat after training, which basically does not lose points. A freezebn will be added in the middle of multiple tasks, so that the counted bn can be applied to each task.

For complex models, a step calibration will be added. The key point here is calibration. Take our end-to-end model deployment as an example. As far as the single-task model is concerned, there are many drop points in the early end-to-end direct float training qat. After consulting my colleagues in the tool chain, I suggest that we do calibration. However, after calibration, it is found that although qat has been greatly improved, it still has a big gap with float. Colleagues in the tool chain suggest fixing the scale of weight or feature. Actually, it is more effective to fix the scale of the feature, but it does not completely solve the problem of qat output of the above tasks from end to end.

So what’s the problem? I also went to some pits. In fact, it is very simple to think about it now. We need to calculate the appropriate feature scale and select the appropriate data when doing calibration. For example, in the early stage, we used the data of urban scenes to estimate the feature scale of speed, and found that the qat index of the trained qat model in high-speed scenes was worse than that of the float. Later, through the tools of the tool chain, the model was analyzed layer by layer and it was found that the problems on the model could not be found. If there is nothing wrong with the model, it is a problem with the data. Finally, we use a high-speed data set. Because calibration itself has few training steps, it is necessary to select the quantity that can cover the perception and reach the upper and lower limits of the maximum and minimum values, so as to estimate a more suitable quantitative scale.

Despite this step, the problem of quantification has been greatly solved. However, the standard of tool chain is generally that the gap between qat and float cannot be greater than 1%. After these two steps, it still can’t reach this level. So what else went wrong? Later, it was also a groping, and it was found that many quantities of 3D perception on BEV were physically meaningful. The final conclusion is to fix the scale for some physical computing layers. Where does the fixed scale come from? For example, as mentioned earlier, the feature on the query index BEV has warping operation, and it has clear physical significance to calculate the two inputs of offset. When the model structure is determined, the maximum and minimum values of the meshgrid on BEV, as well as the maximum and minimum values of the query index, have been determined, so that the maximum and minimum values of the matrix can be calculated, and then the fixed scale can be calculated.

For example, taking odometry as the model input, the data of calibration may be collected at a medium speed, but the speed of the self-propelled vehicle may also change during the actual large-scale data training. Therefore, the maximum and minimum values can also be obtained for this physical quantity with clear rules. With a similar idea, check some numerical calculation layers with physical significance in the network and calculate the fixed scale. Through these operations, the qat problem of the end-to-end model is solved, and it is also a lot of experience. Let’s share it with you.

Quantization is compilation. Compilation means that the compiler directly converts the intermediate format hbir from qat, and finally gets the hbm format deployed on the real board. The specific details are also shared and introduced later. Here is mainly about the performance of BEV perception in actual deployment.

The large-scale BEV is the perception range of 100 forward, 30 backward and 50 left and right respectively, and the small-scale BEV is the perception range of 20 forward and 10 meters in the other three directions, so as to do the element perception on BEV. On the single core of Journey 5, such as a small parking area, the multi-task model of single core and single frame can reach more than 70fps; The wide range of driving can also reach more than 30fps. Even with end-to-end, the model directly output to trajectory prediction can reach more than 20fps, which is in the case of single core. There are two cores on Journey 5, and the frame rate can be further improved in model scheduling.

At the time of deployment, the generalization of the model is tested. Because the model of the customer’s car is different, the corresponding camera installation position and orientation may be different. Our BEV model, especially in the prototype development stage, has many customers who have been verified in the early stage, so a model can support the deployment of multiple models as much as possible, which requires a high generalization of the model. We have also explored a lot, and finally found that the four-plane spatial fusion method introduced earlier has laid a good foundation at the beginning. The example given here is that the training data are all collected by SUV, and the data of cars are used for evaluation. If it is a single plane, it has more than seven drop points compared with four planes.

On the basis of better generalization of the four planes, we will develop some enhancement strategies for training. There are two effective methods here: one is that the BEV model disturbs the image by the camera rpy in one stage, simulates the bumps in the process of vehicle driving, and enhances the image; In addition, it is assumed that the plane is in the place where the angle of view is converted, and then the plane enhancement is made on the plane where the camera leaves VCS, which is also assumed to be the disturbance of rpy.

With these two disturbance strategies, this performance (AP 72.60) can be achieved in the training and training of SUV models and measured in the car data set, which is similar to the performance of an adaptive car model that we have trained with nearly 1 million data collected in about 20 days. Therefore, these strategic feature ensure the generalization of our current BEV perception model in actual deployment.

After deployment, the speed of closed-loop iteration of the model is tested. Especially in the verification stage of the previous prototype scheme, the demo closed-loop verification of different real vehicle installation and deployment is supported through a total version. For the BEV training framework, any camera configuration can be supported. For example, 11v/9v/7v, 7v may replace the 4v panoramic view with 4v fisheye, or any other multiple perspectives, all of which can participate in the model training. When deploying, compile according to the corresponding camera configuration, and then you can do the corresponding test.

The other is the training speed of the model, especially after the time series fusion. Without optimization, if a single frame is trained for 5 days and 10 frames are linear, it will bring 10 times the training time, which is definitely unacceptable. We definitely need to do optimization, and some students who have developed the framework specially guide us to do optimization. At present, the training speed has increased by 56% after optimization.

Specifically, at present, the multi-task release, multi-task with more than a dozen task heads, and the end-to-end training of time sequence can be completed within one week. The later evaluation or the case CICD of some historical data are all automated, thus ensuring the efficiency of the training and distribution step.

Another important factor, especially in the early stage of real vehicle testing, will feed back some non-working case-bad case data. How to use these data in training? There are generally two kinds of optimization for Badcase: one is to mine from the collected data, which is more conventional; The other is to be able to use the returned Badcase data directly.

For things like 2D perception, the link we did in mass production before was relatively mature. For BEV perception, the difference is to see how the model of the brush library comes from or how the data sent to the target comes from. For dynamics, a pure visual large model is used, which is not limited by on-board op and computational power. We have a big model team, and the pure visual BEV big model specially developed has also been used in the dynamic Badcase processing link to generate a pseudo GT to participate in the training. Static, a purely visual mapping scheme, can also send the base map to the standard, and has been deployed to the static perception Badcase link on BEV. In fact, after the deployment of the model, many of them are infrastructure problems. At present, the infrastructure of horizon’s perception of BEV is basically mature.

That’s all I shared today, mainly to convey a few meanings. First of all, based on the fact that Journey 5 can do many things, we have also done many things on it. For the BEV sensing scheme, we can see that we have a better baseline for reference and iteration, so the conclusion is relatively solid.

In addition, if some online students are developing based on Journey 5, or are about to develop based on Journey 5, when you encounter quantitative problems, don’t give up too early. Besides considering the model structure, analyze the data from the perspective of physical meaning and give it a suitable scale.

Finally, I wish everyone a smooth development, and my sharing today is over. Thank you!

　　Xinhua News Agency, Taiyuan, August 18th (Reporter Fan Xinyang, Zhang Zhe) From early morning till late at night, the emergency department never "closes". Whether it is the first aid in the middle of the night or the ward round in the morning, every moment of persistence is awe and commitment to life.

　　August 19th is the Physician’s Day in China. The reporter recorded the 24-hour working status of the emergency department of Shanxi Bethune Hospital (Tongji Shanxi Hospital) in Taiyuan City, Shanxi Province.

　　17 o’clock

　　5 pm is the time when many people are ready to get off work, but for the emergency department, the real busy period has just begun. At this time, outside the emergency room, patients have begun to line up in turn, and emergency doctors respond to every "critical and urgent" patient quickly and orderly, guarding every life in need with professionalism and dedication.

　　18 o’clock

　　At 8 am and 6 pm, it is the emergency shift time. Each round of emergency doctors need to be on duty for about 12 hours, and there are usually a new group of patients from 8 am to noon. The emergency department in the afternoon is a little quiet, and the emergency department enters a busy period at 6 pm.

　　19 o’clock

　　At 7 o’clock in the evening, the head nurse organized new nurses and intern nurses to study the theoretical knowledge of emergency and practice training in the conference room, and one of them was reporting her own topic.

　　20 o’clock

　　Entrusted by the emergency doctor, the nurse, together with the patient’s family, accompanied the patient to do brain CT. In the emergency department, all examinations, instruments and equipment are on-line all the time to protect patients’ lives and health at all times.

　　<扑克游戏> Blackjack <时间> 9 p.m./nine o’clock at night

　　Unlike other departments that sort out cases at fixed points, in emergency, doctors will sort out cases at any time and recycle them to the medical record department in time. Medical record recovery plays an important role in protecting patients’ privacy, improving medical quality and safety, and assisting medical research and education.

　　22 o’clock

　　At 10 o’clock in the evening, the nurse first established venous access for patients entering the emergency room.

　　23 o’clock

　　At 11 o’clock in the evening, an 88-year-old man suddenly suffered from renal failure in the emergency room. The emergency doctor performed femoral vein puncture for him and performed hemofiltration at the bedside.

　　0 o’clock

　　The emergency room ward in the middle of the night is different from the wards of other departments in the hospital. New patients may flood in at any time, and existing patients may also have new emergencies. In the early hours of the morning, compared with the tranquility of other wards, emergency doctors, nurses and patients’ families are still busy in the ward.

　　1 o’clock

　　At 1 o’clock in the morning, an old man in the emergency ward was diagnosed with intracranial infection, and the emergency doctor called the doctor on duty in the neurology department for consultation. According to the regulations, under normal circumstances, patients can’t stay in the emergency department for more than 24 hours, so emergency doctors need to find the most suitable treatment plan for patients within a limited time. Call doctors from all departments of the hospital at any time to assist in diagnosis and treatment, in order to facilitate the patient’s subsequent hospitalization.

　　2 o’clock

　　The early morning is a busy time in the emergency surgical rescue room. Patients injured in unexpected situations such as car accidents were sent to the emergency department. After transporting a patient injured in a car accident, the 120 ambulance team is cleaning up the blood stains on the ambulance.

　　3-4 o’clock

　　The emergency room in the middle of the night is rarely quiet. In the corner of the emergency hall, there are several stretchers on standby. "We definitely hope that there will be fewer patients, and it is best not to use these stretchers." An emergency doctor said.

　　5 o’clock

　　At dawn, the emergency department returned to some tranquility, and the emergency doctor on duty finally had time to lie in the rest room for a while, preparing for the morning shift and rounds.

　　6 o’clock

　　At 6 o’clock in the morning, the emergency doctor on the night shift finally had a chance to eat something to replenish his strength. The doctor on duty was sending breakfast pancakes to the lounge and informing other doctors and nurses in the WeChat group to take time to eat.

　　7 o’clock

　　At 7 o’clock in the morning, many people just got up to go out to work, and emergency doctors have been on standby for a long time, always ready to deal with emergencies. At this time, the instruments in the emergency ward are fully on standby, ready to provide services for new patients. The difference between the emergency department and other departments is that all kinds of rescue equipment are concentrated here, and you can find a transfer ventilator, Saab resuscitator, electrocardiogram machine and so on in one ward. Emergency doctors not only need to respond quickly, but also operate these devices skillfully, and strive to rescue patients effectively in the first time.

　　8 o’clock

　　At 8 o’clock in the morning, the emergency doctors on the night shift began to hand over to the doctors on the day shift, from the triage desk, nurses to doctors to introduce the existing patients in the ward in turn. Beginning with the handover, but not limited to the handover, the emergency director usually discusses the patient’s situation and the follow-up treatment at the handover meeting.

　　9 o’clock

　　After handing over the basic situation, two classes of doctors will come to the ward of the emergency room to further confirm and discuss the patient’s data and complete the final handover between day and night.

　　ten o’clock

　　The patients in the emergency observation room are a relatively minor group in the whole emergency ward. Compared with other emergency patients, they may be lucky enough to leave the emergency room after infusion.

　　11 o’clock

　　Near noon, several workers were in the emergency room, and their arms were injured while working on the construction site. Among the patients admitted to the surgical emergency department, people engaged in high-risk manual labor account for a relatively high proportion.

　　12 o ‘clock

　　Family members of patients bring hot porridge cooked at home for patients with mobility difficulties. Family care and love is the most simple and warm scene in the emergency room.

　　13 o’clock

　　At 1 o’clock in the afternoon, outside the emergency room, the patient’s family hurriedly pushed a patient. The patient was unconscious and lost consciousness. The nurse hurriedly pushed the patient into the emergency treatment room and quickly informed the emergency doctor.

　　14 o’clock

　　120 Emergency Center personnel go to the triage desk to connect the patient information and situation with the nurse after completing the patient transportation. Race against time and life, the shirts of 120 ambulance workers have been soaked with sweat.

　　15 o’clock

　　In the afternoon, the emergency department is a relatively relaxing time, and it is rare to be quiet in the emergency department. Families in twos and threes rest in the empty corridor.

　　16 o’clock

　　If there are no new patients in the emergency rescue room, nurses will use their spare time to practice the rescue practice skill-"simple respirator assisted breathing", which can assist patients with ventilation disorders to increase ventilation and improve ventilation function.

　　Through the moments recorded by the camera, we can see that whether it is waiting in the morning or racing against time in the evening, the emergency department doctors and nurses are always in the front line, striving for precious time for every life in need with selfless dedication and professional skills.

　　On the occasion of China Physician’s Day, I pay tribute to these medical workers who are guarding the front line of life.

　　Moral education curriculum is the most important carrier of moral education in primary schools. Reviewing the changes of moral education curriculum in primary schools since the founding of New China 70 years ago, and summarizing the experience of moral education curriculum construction will help to better implement the fundamental task of cultivating people by virtue and cultivate socialist builders and successors.

　　Four stages of the development of moral education curriculum in primary schools and their characteristics of the times

　　Before the reform and opening up &mdash; &mdash;

　　There is no unified moral education curriculum.

　　In March, 1952, the Ministry of Education promulgated the Provisional Regulations for Primary Schools (Draft), pointing out that primary education should "give children a comprehensive basic education", in which the purpose of moral education is to make children have good qualities such as patriotism, national morality, honesty, courage, unity, mutual assistance and discipline, and the main content is the "five loves" education of loving the motherland, people, labor, science and public property. In 1953, the State Council issued the Instruction on Rectifying and Improving Primary School Education, and primary school moral education began to emphasize the education of daily behavior norms. The first primary code, published in 1955, put forward specific requirements for the daily behavior norms of primary school students. Generally speaking, from the founding of New China to 1956, moral education in primary schools focused on the cultivation of moral quality and behavior habits, which was more in line with children’s characteristics. However, with the expansion of the "anti-Rightist" struggle in 1957, this situation has undergone great changes.

　　In April 1958, the Central Committee of the Communist Party of China held a national conference on education. The meeting pointed out that education is a tool of class struggle and should serve politics and production. In September of the same year, the Instructions of the Central Committee of the Communist Party of China and the State Council on Education clearly stated that "the Party’s educational policy is that education serves the politics of the proletariat and combines education with productive labor". Since then, moral education courses have shifted from paying attention to moral education to political education. Jiangsu, Zhejiang and other places took the lead in setting up political courses in primary schools, and then gradually expanded to most parts of the country. At the same time, the Ministry of Education requires primary schools to add a class meeting every week to educate students on current affairs and politics, and the political tendency of moral education in primary schools begins. During the ten-year "Cultural Revolution" that began in 1966, the normal school education order was destroyed and school moral education was completely politicized.

　　Reform and opening up to the end of the 20th century &mdash; &mdash;

　　From political lessons to ideological and moral lessons

　　Before the reform and opening up, there was no unified national curriculum for moral education in primary schools. In 1978, the Ministry of Education promulgated the "Trial Draft of Full-time Ten-year Primary and Secondary School Teaching Plan", which stipulated that politics classes should be offered in the fourth and fifth grades of primary schools, with two class hours per week, mainly to carry out preliminary communist ideological education and necessary political knowledge education. The unified political course has not changed the political tendency of moral education in primary schools, but it was abolished in 1981, so it can be regarded as a transition. However, it is the first time in New China to explicitly set up a political course in the teaching plan, which is of great institutional significance for moral education to get on the right track.

　　From April 22 to May 7, 1979, the Ministry of Education held a national symposium on ideological and political education in primary and secondary schools. After the symposium, the Minutes of the National Symposium on Ideological and Political Education in Primary and Secondary Schools were issued, which criticized the formalism and adult practices in moral education and pointed out that "the ideological and political work of primary and secondary school students must proceed from reality, pay attention to the age characteristics of teenagers, be targeted and stress practical results". This has played a positive role in correcting the politicization and adult tendency of primary school political lessons. In March 1981, the Ministry of Education promulgated the "Full-time Five-year Primary School Teaching Plan (Revised Draft)". In the "Explanation on Revising the Teaching Plan of Full-time Five-year Primary School", it is pointed out in particular: "At present, the political lessons in the fourth and fifth grades are divorced from the students’ ideological reality, and the effect is not good. According to the spirit of adhering to the Four Cardinal Principles and strengthening ideological education for young people, the current political class will be changed into an ideological and moral class, with one class hour per week for grades one to five. " From the primary school political lesson in 1978 to the primary school ideological and moral lesson in 1981, this important change has effectively corrected the tendency of politicization and adulthood of primary school moral education, and turned primary school moral education into cultivating students’ moral quality.

　　In 1982, the Ministry of Education promulgated the "Teaching Outline of Ideological and Moral Courses for Full-time Five-year Primary Schools (Trial Draft)", stating that the purpose of ideological and moral courses for primary school students is to "make primary school students initially have communist moral quality and good behavior habits, and aspire to be workers with ideals, morality, culture and discipline, so as to lay an ideological foundation for training them to be successors of the proletarian cause". Around this goal, the ideological and moral course takes "five loves" (love the motherland, love the people, love labor, love science and love socialism) as its basic content, and combines with the implementation of primary code to educate primary school students on the moral quality and behavior norms that citizens in socialist countries should have, and strives to arrange the teaching content reasonably according to the age characteristics of primary school students. This is the first time that New China has systematically and scientifically constructed the content system of moral education courses in primary schools. Later, according to the requirements of social development and the needs of the situation, the syllabus of ideological and moral course in primary schools (1986), the syllabus of ideological and moral course in full-time primary schools with nine-year compulsory education (preliminary draft) (1990) and the syllabus of ideological and moral course in full-time primary schools with nine-year compulsory education (for trial implementation) (1992) were promulgated successively. Through the continuous revision of the syllabus, the content of ideological and moral course is more in line with the age characteristics of primary school students, and it is more moral enlightenment and life-oriented for primary school students.

　　In 1994, "Several Opinions of the Central Committee of the Communist Party of China on Further Strengthening and Improving Moral Education in Schools" was promulgated, pointing out that the moral education system in schools should be planned as a whole. To implement this opinion, in 1997, the State Education Commission issued "Curriculum Standards for Ideological and Moral Courses in Primary Schools and Junior High Schools in Nine-year Compulsory Education (Trial)", which is the first time to replace the syllabus with curriculum standards, and to determine the teaching objectives and requirements of moral education courses in primary schools and junior high schools as a whole, plan the teaching content system of ideological and moral courses in primary schools and junior high schools, and complete the task of integrating ideological and moral courses in primary schools with junior high schools.

　　Compared with the previous syllabus, the curriculum standard of primary school ideological and moral course in 1997 emphasized the cultivation of good moral quality and civilized behavior habits, and highlighted the foundation and extensiveness of moral education. In the form, it emphasizes the hierarchy, stage, continuity, step by step and spiral rise of teaching.

　　New Curriculum Reform in the 21st Century &mdash; &mdash;

　　Offering courses on morality and life, morality and society in stages.

　　In 2000, the general offices of the General Office of the Central Committee of the CPC and the State Council issued the Opinions on Further Strengthening and Improving Moral Education in Primary and Secondary Schools to Adapt to the New Situation, proposing that we should proceed from reality, thoroughly study the current ideological and moral characteristics of students, revise the curriculum standards of ideological and moral courses in primary schools and ideological and political courses in middle schools, further reform and improve the teaching content, and strive to build a moral education curriculum system in primary and secondary schools to meet the needs of development in the 21st century. According to this opinion, the Ministry of Education made necessary revisions to the curriculum standards of ideological and moral education in 1997, and in 2001, it promulgated the Curriculum Standards of Ideological and Moral Education in Primary Schools and Ideological and Political Education in Junior High Schools for Nine-year Compulsory Education (Revised). However, with the start of the new curriculum reform in 2001, the ideological and moral course has been changed into moral and life, moral and society, with new curriculum standards. In 2001, the curriculum standards of ideological and moral education in primary schools only played a transitional role.

　　In June 2001, the Ministry of Education promulgated the Outline of Basic Education Curriculum Reform (Trial). The "Outline" proposes "to set up a nine-year compulsory education curriculum as a whole". In primary school, comprehensive courses are the main courses, and morality and life are offered in lower grades, while morality and society are offered in middle and high grades. In 2002, the Ministry of Education officially promulgated the Curriculum Standards of Morality and Life in Full-time Compulsory Education (experimental draft) and the Curriculum Standards of Morality and Society in Full-time Compulsory Education (experimental draft).

　　From ideological and moral course to moral and life, moral and society, these two course standards and ideological and moral course standards have changed greatly in course nature and design ideas. The changed course name emphasizes activity and comprehensiveness more, which is more suitable for the characteristics of primary school students in low and middle grades. Moral and life curriculum is connected with kindergarten curriculum, which is an active comprehensive curriculum based on children’s life and aimed at cultivating children with good moral character, willingness to explore and love life. It is designed according to three axes: children and self, children and society, and children and nature. Morality and Society course is a comprehensive course based on children’s social life and promoting students’ good moral character formation and social development. It focuses on children’s social life, from individual, family, school to community, hometown, motherland and the world, and forms six modules, such as "I am growing", "I am with my family", "I am with my school", "I am Chinese" and "approaching the world". In 2011, the state promulgated the curriculum standards of Morality and Life, Morality and Society (2011 edition), which kept pace with the times in content and reflected the requirements of the times. At this stage, the management of teaching materials is "one syllabus and many books", which is examined and approved by the textbook review Committee of primary and secondary schools of the Ministry of Education.Multiple sets of teaching materials are selected for use at the same time.

　　Entering a new era &mdash; &mdash;

　　Use the unified textbook "Morality and Rule of Law"

　　On October 23, 2014, the Fourth Plenary Session of the 18th CPC Central Committee adopted the Decision of the Central Committee of the Communist Party of China on Several Major Issues Concerning Comprehensively Advancing the Rule of Law, which proposed that the rule of law education should be integrated into the national education system, and the rule of law knowledge courses should be set up in primary and secondary schools. To implement this Decision, in June, 2016, the Ministry of Education, the Ministry of Justice and the National Law Popularization Office jointly issued the Outline of Youth’s Legal Education, requiring timely and corresponding revision of moral education curriculum standards in primary and secondary schools to complete the teaching content required by the outline. Starting from the fall semester of 2016, the state has changed Morality and Life, Morality and Society in primary schools and Ideology and Morality in junior high schools into Morality and Rule of Law, and set up special books on the rule of law in the second volume of grade six and the first volume of grade eight.

　　On the one hand, the compilation of the textbook Morality and Rule of Law for primary schools is based on the curriculum standards of Morality and Life, Morality and Society and the Outline of Education for Teenagers under the Rule of Law; on the other hand, it is based on the fundamental task of cultivating people in the new era, highlighting the guidance of socialist core values, and strengthening the education of Chinese excellent traditional culture, revolutionary culture, rule of law, national sovereignty awareness and national unity. "Morality and Rule of Law" is compiled by the Ministry of Education, with "one syllabus and one book", reviewed by the National Textbook Committee and used nationwide. Since 2017, the unified textbooks have been used in the first and seventh grades, in the second and eighth grades in 2018, and in the autumn of 2019, all grades will be fully covered. In January 2019, the Ministry of Education initiated the revision of the curriculum standards for compulsory education, and the curriculum standards for Morality and Rule of Law are currently being formulated.

　　Future-oriented,Constructing the overall moral education curriculum suitable for children

　　Since the founding of New China 70 years ago, moral education courses in primary schools have grown from scratch, from political lessons to ideological and moral lessons, from ideological and moral lessons to morality and life, morality and society, and then to morality and rule of law in the new era. The course has both a changing side and a constant side. What remains unchanged is the initial intention of moral education curriculum &mdash; &mdash; To cultivate all-round socialist builders and successors, the contents and organizational forms of moral education have changed, such as from a single political education to paying attention to moral education and then to both morality and law, from instilling political dogma to constructing children’s moral life, from meeting the requirements of society to meeting the common needs of social development and individual development, from "one program with many books", choosing to use one program with one book, and using it in a unified way.

　　Looking forward to the new era, the development of moral education curriculum in primary schools should achieve four points: first, put the moral education curriculum in primary schools into the overall framework of "the integration of moral education in colleges, middle schools and primary schools" and design the moral education curriculum in primary schools step by step and spirally. Second, take children as the center, construct children’s moral life, including children’s communication life with themselves, others, society, country and the world, transcend individuals and realize the integration of individuals and society. Third, construct the content system of "Great Moral Education" course. Moral education is not only a political course, but also an ideological and moral course. It is a "grand moral education" that includes ideological and political education, moral education, rule of law education, psychological education and traditional culture education. The content of moral education not only has a stable side, but also keeps pace with the times and embodies the times. Fourth, highlight the national will of moral education curriculum. General Secretary of the Supreme Leader pointed out: "Ideological and political course is the key course to implement the fundamental task of Lide Shuren." In the new era, we must adhere to the Party’s overall leadership over the construction of ideological and political courses, make unremitting efforts to cultivate people with Socialism with Chinese characteristics Thought, the supreme leader of the new era, strive to cultivate new people of the times who are responsible for national rejuvenation, and cultivate socialist builders and successors who are fully developed morally, intellectually, physically and artistically.

　　The Central Rural Work Conference was held in Beijing from December 28th to 29th. The meeting put forward the road of rural revitalization in Socialism with Chinese characteristics for the first time, and clearly defined the timetable and road map of rural revitalization strategy. The meeting made it clear that by 2020, important progress will be made in rural revitalization, and the institutional framework and policy system will basically take shape; By 2035, decisive progress will be made in rural revitalization and agricultural and rural modernization will be basically realized; By 2050, the countryside will be fully revitalized, and strong agriculture, rural beauty and farmers’ wealth will be fully realized.

　　The 19th National Congress of the Communist Party of China clearly put forward the strategy of rural revitalization for the first time. This is the general strategy to promote China’s agricultural and rural modernization in the future, and it is also the general starting point for China’s "three rural" work in the future. To truly revitalize the countryside, we must use the idea of reform and innovation to remove all kinds of obstacles that hinder the development of agriculture and rural areas, stimulate the potential of various rural elements and the vitality of various subjects, and continuously inject new kinetic energy into the development of agriculture and rural areas.

　　First, closely focus on the fundamental goal of simultaneous modernization of agriculture and rural areas

　　Since the beginning of the new century, how to build a well-off society in an all-round way has become a top priority for China’s economic and social development. The 16th, 17th and 18th National Congress of the Communist Party of China are all based on the strategic goal of building a well-off society in an all-round way in 2020, and put forward requirements and arrangements for the work concerning agriculture, countryside and farmers. The 16th National Congress of the Communist Party of China clearly pointed out that it is an important task for building a well-off society in an all-round way to coordinate urban and rural economic and social development, build modern agriculture, develop rural economy and increase farmers’ income. The 17th National Congress of the Communist Party of China emphasized that it is necessary to strengthen the basic position of agriculture, take the road of agricultural modernization with China characteristics, establish a long-term mechanism to promote agriculture through industry and bring rural areas through cities, and form a new pattern of integration of urban and rural economic and social development. The 18th National Congress of the Communist Party of China once again stressed that the integration of urban and rural development is the fundamental way to solve the problems concerning agriculture, rural areas and farmers. It is necessary to intensify the overall planning of urban and rural development, enhance the vitality of rural development, gradually narrow the gap between urban and rural areas, and promote the common prosperity of urban and rural areas. Under the correct leadership of the CPC Central Committee, in the process of building a well-off society in an all-round way in the past decade or so, China’s agricultural and rural development has made historic achievements and undergone historic changes.

　　While affirming the achievements, we should also be soberly aware that the dual structure of urban and rural areas is obviously still the biggest structural problem in China at present, and the lagging development of agriculture and rural areas is the most prominent manifestation of insufficient development imbalance in China. From the perspective of income and consumption, although the income and consumption expenditure of rural residents have increased faster than that of urban residents in recent years, in 2016, the per capita income and consumption expenditure of urban residents in China were still as high as 2.72 times and 2.28 times that of rural residents, respectively, and the penetration rate gap of household cars, air conditioners, computers and other durable consumer goods between urban and rural residents is still very large. From the perspective of overall labor productivity, in 2016, non-agricultural industries reached 121,300 yuan per capita, while agriculture was only 29,600 yuan, the former was 4.09 times that of the latter. From the perspective of infrastructure, in 2016, 46.2% of rural households in the country used ordinary dry toilets, and even 2% of households did not have toilets; 26.1% of village domestic garbage and 82.6% of village domestic sewage have not been treated centrally or partially; 38.1% of the main roads in the village have no street lamps. From the perspective of basic public services, in 2016, 67.7% of the villages did not have kindergartens or nurseries; 18.1% of villages have no clinics, and 45.1% of villages have no licensed (assistant) doctors. From the perspective of social security, the current rural minimum living security, new rural insurance and new rural cooperative medical insurance standards are also significantly lower than those of urban residents and urban workers. This is only the gap in quantity. If we look at the quality, the gap between urban and rural areas will be even greater.

　　According to the deployment of the 19th National Congress of the Communist Party of China, China will basically realize socialist modernization in 2035, which is 15 years ahead of the previous deployment. In 2050, China will be built into a prosperous, strong, democratic, civilized, harmonious and beautiful socialist modernization power, which is higher than the goal described before. Although new changes and progress will take place in the process of building a well-off society in an all-round way in the next three years, the dual structure of urban and rural areas in China will still be quite prominent when the goal of building a well-off society in an all-round way is achieved in 2020. From this starting point, China will enter a new journey of building socialist modernization in an all-round way. How to keep up with the pace of national modernization in agricultural and rural development is a major challenge before us. If the key to a well-off society depends on fellow villagers, then it can also be said that the key to modernization is agriculture and rural areas. The fundamental starting point of implementing the rural revitalization strategy is to keep the modernization of agriculture and rural areas in sync with the modernization of the whole country.

　　Second, firmly grasp the two principles of priority development and integrated development

　　Under the background of the obvious dual structure of urban and rural areas, in order to promote the synchronization of agricultural and rural modernization and national modernization, we must deepen our understanding of the important assertion that "the problem of farmers in agricultural and rural areas is a fundamental problem related to the national economy and people’s livelihood" and truly "always solve &lsquo; Agriculture, countryside and farmers &rsquo; The issue is the top priority of the whole party’s work. " In particular, it is necessary to implement the new development concept and adhere to the priority development of agriculture and rural areas and the integration of urban and rural development.

　　Adhering to the priority development of agriculture and rural areas means giving full play to the role of the tangible hand of the government and making efforts to make up for the shortcomings of national modernization. The focus is on two aspects: first, promote the priority allocation of public resources to agriculture and rural areas. This is an urgent need to eliminate the stock gap of basic public services between urban and rural areas, and it is also an inevitable requirement to prevent the incremental gap of basic public services between urban and rural areas. After years of hard work, the "four beams and eight pillars" of the rural basic public service system have been set up, realizing a historic change from "nothing" to "something". At present, the main problem is that the gap between urban and rural areas in the field of public services is still too large, and the level of protection of rural public services is too low. We should take "having" as the main direction, continue to promote the integrated development of urban and rural compulsory education, focus on improving the quality and convenience of rural compulsory education, improve the basic old-age insurance system for urban and rural residents, focus on increasing farmers’ basic pension, improve the unified basic medical insurance system and serious illness insurance system for urban and rural residents, focus on increasing the proportion of farmers’ reimbursement, coordinate the urban and rural social assistance system, and focus on improving the standard and coverage of rural minimum living security. Increase investment in rural roads, water supply, power supply, communications and other infrastructure, and accelerate the construction of rural domestic garbage and sewage treatment capacity. The second is to improve the effectiveness of agricultural support and protection policies. In recent two years, the state has begun to adjust and improve agricultural support and protection policies.Such as the implementation of cotton target price subsidy pilot, the implementation of corn "market acquisition+producer subsidies", and the promotion of agricultural "three subsidies" system reform. In the future, China’s agricultural support and protection policy should continue to increase, and the key is to adjust the focus of the policy. We should highlight the direction of competitiveness, increase investment in farmland water conservancy, land consolidation, agricultural science and technology, and professional farmers’ training, so as to promote agricultural cost reduction and efficiency improvement. We should also highlight the direction of green ecology, increase investment in returning farmland to forests, returning farmland to wet areas and beaches, water-saving irrigation, farmland fertility protection, reduction of fertilizers and pesticides, recovery of agricultural wastes, over-exploitation of groundwater and treatment of areas polluted by heavy metals, so as to promote the sustainable development of agriculture.

　　Adhering to the integrated development of urban and rural areas means giving play to the role of the invisible hand of the market and making great efforts to promote the quality change, efficiency change and power change of agricultural and rural development. China’s agriculture and rural areas have changed from a high-speed growth stage to a high-quality development stage. To achieve high-quality development requires the rationalization of urban and rural resource allocation and the integration of urban and rural industrial development. In the future, solving the problems concerning agriculture, rural areas and farmers will depend on the strength of towns, and solving the problems of cities will also depend on the strength of villages. Cities and villages should be harmonious, interactive and interdependent. First, rural areas should respond sensitively to the new needs of cities and towns. The demand of urban residents for agricultural products has been well met, but the demand for agricultural products quality has not been well met; Rural areas are required to provide not only sufficient and safe material products, but also ecological products such as clean air, clean water, quiet rural scenery, and spiritual products such as farming culture and homesickness. To catch these new demands, we should accelerate the transformation of agricultural development from increasing production to improving quality, and vigorously develop new industries and formats such as rural leisure tourism and old-age care. Second, cities and towns should respond sensitively to the new needs of rural areas. To develop resource-saving and environment-friendly agriculture, new fertilizers and low-toxicity and high-efficiency pesticides are urgently needed; To promote "machine substitution" in the agricultural field and improve agricultural labor productivity, agricultural machinery with high cost performance is urgently needed, especially small agricultural machinery suitable for hilly and mountainous areas and cash crop production; Improve the rural living environment, improve the quality of life of farmers,There is an urgent need for new building decoration materials, solid and durable garbage and sewage treatment equipment, economical and applicable kitchen and bathroom and other household necessities. To catch these new demands, we should speed up the adjustment of the technical structure and product structure of industrial departments and improve the pertinence and efficiency of "industrial products going to the countryside".

　　Third, earnestly grasp the three keys of "people, land and money"

　　The implementation of rural revitalization strategy is a systematic project, which requires scientific planning and comprehensive promotion of various revitalization measures in accordance with the general requirements of "prosperous industry, ecologically livable, civilized rural customs, effective governance and affluent life". The core is to grasp the three keys of "people, land and money":

　　(a) to promote the decline in the proportion of rural population and structural optimization. In 2016, the proportion of rural population in China is still as high as 42.65%, and the proportion of employment in the primary industry is also as high as 27.7%. A considerable part of the urban resident population from rural areas has not been fully integrated into the towns where they are employed and live. Generally speaking, China is still in the development stage of "to be rich, farmers must be reduced". We must unswervingly promote the new urbanization with people as the core and continue to promote the rural population to enter cities and the transfer of agricultural labor force. At the same time, we should also note that the rural population entering the city and the transfer of agricultural labor force in China are characterized by "elite immigrants", and the population entering the city and the transferred labor force are obviously superior to those staying in the countryside in terms of age, education level and gender ratio. To realize rural revitalization, we must pay attention to optimizing the rural population structure and improving the quality of rural human capital while promoting the decline of the proportion of rural population. It is necessary to optimize the structure of agricultural practitioners and speed up the training of modern young farmers, leaders of new agricultural business entities and agricultural professional managers. We should not only pay attention to discovering and cultivating new professional farmers from those who are still in rural areas, but also pay attention to guiding some willing migrant workers to return home, college students who have come out of rural areas to return home, and all kinds of talents who have grown up in cities to the countryside, and introduce modern science and technology, production methods and business models into agriculture and rural areas. Speed up the training of a "three rural" work team that understands agriculture, loves the countryside and loves farmers.Comprehensively improve the ability and level of national civil servants, scientific and technological personnel, teachers and doctors in rural areas.

　　(2) Accelerate the establishment of a land security mechanism for rural revitalization. Deepening the reform of rural land system is an urgent need to promote the construction of modern agriculture and develop new industries and formats in rural areas. First, we should improve the method of "separation of powers" in rural land with the goal of agricultural modernization. With the changes in the employment structure, income structure and even residence of contractors, the gradual withdrawal of the "first generation of farmers", the reluctance of Nong Erdai to farm, and the improvement of the social security system in urban and rural areas, the livelihood guarantee function of contracted land is declining, and the function of production factors is highlighted. Therefore, we should adjust and improve the empowerment of collective ownership, farmers’ contracting rights and land management rights to prevent land abandonment and excessive increase in land rent. Second, we should improve the management policy of agricultural facilities land. More flexible and relaxed management policies should be implemented for facilities such as cold chain, primary processing, leisure picking and storage of agricultural products, and supporting land such as parking lots, toilets and restaurants. Third, we should optimize the layout of urban and rural construction land. Effectively implement the existing policy of "determining a certain proportion of the annual new construction land plan indicators to support new rural industries and new formats". Prudently improve the operation methods of linking the increase and decrease of urban and rural construction land and balancing the occupation and compensation of cultivated land, leave land space for rural revitalization, and do not rush to relocate rural construction land to cities or underdeveloped areas to developed areas. Fourth, we should explore effective ways to revitalize rural idle homesteads. On the premise of not buying and selling rural homesteads,Actively explore specific ways to effectively use rural idle homesteads. For example, rural collective economic organizations can save construction land such as village renovation and homestead consolidation, and develop rural leisure tourism and pension industries and rural three-industry integration projects by means of shareholding and joint venture. For another example, rural collective economic organizations can make full use of idle farmhouses and homesteads through leasing and cooperation.

　　(3) Establish and improve the institutional mechanisms conducive to the flow of all kinds of funds to agriculture and rural areas. Whether it is to achieve "industrial prosperity" or "ecological livability", it needs a lot of capital investment. We should raise funds for rural revitalization from various channels such as finance, finance and social capital. First, we must reform the financial input mechanism for supporting agriculture. On the one hand, we must persist in taking agriculture and rural areas as the priority areas of fiscal expenditure and ensure a moderate increase in investment in agriculture and rural areas; On the other hand, we should focus on innovating the way of use and improving the efficiency of supporting agriculture. Do a good job in two articles: "integration" and "incitement". "Integration" means giving full play to the leading role of planning, bundling all kinds of agriculture-related funds as much as possible to form a joint force. "Inciting" means giving full play to the leverage of financial funds and guiding financial and social capital to invest more in agriculture and rural areas by means of awards, interest subsidies and guarantees. Second, we must accelerate rural financial innovation. A considerable part of rural deposits can not be converted into investment in rural areas, and it is an urgent practical problem to flow to cities through the siphon effect of financial institutions. It is necessary to take a two-pronged approach from "building mechanisms" and "building institutions". "Building a mechanism" is to implement the incremental incentive policy for agricultural loans.We will implement differentiated supervision and assessment methods for financial institutions that have reached a certain proportion of agriculture-related businesses, appropriately decentralize the business examination and approval authority of county branches, and solve the problem of insufficient enthusiasm for putting in loans for agriculture, rural areas and farmers. "Building institutions" is to optimize the establishment mode of rural banks, improve the coverage of counties and cities, carry out internal credit cooperation of farmers’ cooperatives, support existing large financial institutions to increase county outlets, and solve the problem of insufficient market participants in lending to agriculture, rural areas and farmers. Third, we should encourage and guide social capital to participate in rural revitalization. Encourage social capital to develop modern breeding, agricultural service, agricultural product processing, leisure tourism and pension industries suitable for enterprise management in rural areas. Innovate the interest linkage mechanism and guide social capital to drive farmers instead of replacing them. Strengthen the protection of property rights and stabilize investors’ expectations.

According to the recommendation of Dietary Guidelines for China Residents, adults should eat 200-400g of fruit every day. The 200-400g here refers to the weight of the pulp eaten, excluding the peel, seeds and stones. Take apples as an example. A Fuji apple weighs about 250 grams, and there are 200 grams left after removing the core, so the amount of 400 grams a day is roughly equivalent to eating two apples.

Eating fruit is also very particular. Most fruits have high dietary fiber and sugar content. Eating too much will cause stomach pain, abdominal distension and increase blood sugar. Experts remind that eating fruits should pay attention to diversity. For example, eat an apple, and then eat some strawberries, oranges, etc. in moderation, which not only ensures enough food, but also enriches nutrition.

In the way of eating fruit, many citizens like to drink freshly squeezed juice, which is delicious and simple. In fact, juicing is not as good as eating directly, because juicing will lose dietary fiber, vitamins, reduce satiety and increase the rising speed of blood sugar. Others consider whether the fruit is cooked and eaten well. Some fruits with low vitamin C content and thick meat, such as apples, pears, peaches and bananas, can be considered cooked if they feel uncomfortable or not delicious when eaten raw. Stewed, steamed and roasted taste good. But some fruits are better eaten raw, such as strawberries, grapes, watermelons and other juicy fruits.

The time to eat fruit is also particular. After a night’s rest in the morning, the function of the gastrointestinal tract is still recovering, so it is best to choose fruits that are not too acidic and astringent. People with poor gastrointestinal function should not eat fruits at this time, especially persimmons, oranges and hawthorn. Bananas are also not suitable for eating on an empty stomach, which will speed up the movement of the stomach and increase the burden on the heart. When eating fruit between meals, fructose and glucose in the fruit can be quickly absorbed by the human body. For example, fresh dates are best eaten before meals, but eating too much may cause hyperacidity and bloating. Pineapples can be eaten after lunch, and watermelons are best eaten two hours after meals. Eating fruit 1 hour after a meal helps digestion, and you can choose fruits with high organic acid content such as pineapple and hawthorn. But don’t eat a lot of fruit after dinner, which is not good for digestion, and it is easy to turn fructose into fat and accumulate in the body because of eating too much.

Some fruits are not suitable for everyone, such as kiwi fruit, mulberry, strawberry and other seeded fruits, which can promote defecation, and are more suitable for people with constipation. If it is easy to have diarrhea, don’t eat more. Pineapple, kiwi, mango, fig and other fruits may cause allergic and intolerant reactions in a few people. If there are uncomfortable reactions such as swelling of throat mucosa, headache and stomachache after eating, you should avoid eating them. The sour taste in bayberry, plum, plum and other fruits will stimulate gastric mucosa together with gastric acid, which is not suitable for patients with ulcer disease.

Out of concern about pesticide residues, many people will worry about eating the peels of apples, pears, peaches and other fruits. In fact, they can eat them safely as long as they are carefully rinsed or soaked in salt water before eating. If you are still worried about the safety of the peel, peel it and eat it.

There are many ways to store fruits. It’s best to put apples, pears and other temperate fruits into plastic bags first, and then put them in the refrigerator for preservation. Tropical fruits can’t be put in the refrigerator, or they will be frozen. Just put them in a cool place at room temperature, and leave a little mouth in the bag, and check them frequently to avoid rot.

Experts especially suggest that fruits should not be piled up in a box to avoid squeezing each other. Eat the soft and ripe fruits first, and take out the diseased or moldy fruits immediately to avoid infecting other fruits. Wash those with dirt or mold on the surface gently. If you really can’t finish eating, you can make some fruits into jam, soak them in fruit wine, or soak them in honey.

For obese people, as long as it is not sour fruit, eating before meals is conducive to a sense of fullness, reducing the amount of food for the next meal, and is beneficial to controlling blood pressure and weight. On the contrary, those thin and malnourished people may affect their appetite for dinner if they eat a lot of fruit before meals. (Zheng Haiyan, Wang Biao)

　　[car home Information] Mr. Zhang’s Audi Q7 had a minor accident, and the insurance company later set a loss of more than 80,000 yuan. This price is really not cheap on an ordinary car, but as an imported car, the victim Mr. Zhang does not have much doubts. It’s just that a car lamp with a price of more than 50 thousand yuan appeared in the insurance loss list. In fact, the car lamp was not damaged in the accident. Although Mr. Zhang was puzzled, he still trusted the 4S shop and did not question it. After half a year, Mr. Zhang saw in the maintenance record that the last total maintenance cost was only more than 10 thousand yuan, and where did the remaining less than 70 thousand yuan go? Did it go into the pocket of a 4S shop?

●　In the case of a minor accident, the staff of the 4S shop fixed the damage on their behalf, and the amount of fixed damage was as high as more than 80,000 yuan, and the undamaged headlights were fixed at 50,000 yuan.

　　The 2019 Audi Q7 55TFSI technology driven by Mr. Zhang was out of danger on February 3 this year. The time when Mr. Zhang was out of danger coincided with the Spring Festival, so he was dragged to work on February 7 after the holiday to go through the relevant loss determination procedures. It was the employees of the 4S shop who gave Mr. Zhang a loss determination.

"2019 Audi Q7 55TFSI technology type"

　　According to the vehicle inspection photos taken by the 4S shop, the right front face, the right front fender and the right front wheel of the vehicle are all bruised to varying degrees. The insurance company’s loss-fixing records show that the car’s loss-fixing replacement amount is 82,534 yuan, of which the most expensive accessory is the right front headlight assembly with a loss-fixing price of 50,254 yuan, followed by the front bumper with a loss-fixing price of 13,086 yuan, followed by the right front fender with a loss-fixing price of 6,220 yuan.

"Mr. Zhang’s Audi Q7 test photo"

　　In the inspection photos, the right fender was the most seriously damaged, basically all the fenders were deformed, and there were many scratches on the paint surface and the wheel eyebrows were damaged, so it was really necessary to replace them. The bumper only has scratches on the right front side, and obvious scratches can also be seen on the right wheel rim. However, the right front headlight of the vehicle is not damaged, and it can still be lit normally, and no visible scratches can be seen.

Mr. Zhang’s inspection photos of Audi Q7 right front headlight showed no obvious damage.

　　All the damage assessment procedures went smoothly. After the damage assessment documents came out, Mr. Zhang only had doubts about the damage assessment of the right front headlight. Mr. Zhang said that the right front headlight was inspected on the day of the accident, and there was no damage, but I don’t know why the damage was given. The after-sales staff of the 4S shop said that there was a hole behind the right front headlight, so it needed to be replaced. Although Mr. Zhang had doubts about this, he didn’t think much about it. He thought that the 4S shop should not be faked, so he didn’t pursue it again.

●　Mr. Zhang accidentally found something fishy. 4S shop: The accessories are genuine, but they are not original parts. I hope to sum up for fear of being fined.

　　Mr. Zhang’s car was later repaired by the 4S shop. After half a year, a dramatic scene happened. Before preparing for a major maintenance, Mr. Zhang wanted to check the last maintenance record, so he downloaded an App from FAW Audi. Later, Mr. Zhang found the maintenance record entered by the 4S shop during the last Spring Festival, which showed that the maintenance amount was 13,863 yuan, which was 68,671 yuan lower than the previous loss amount of 82,534 yuan. So where did the 68,671 yuan go? In the 4S shop maintenance record provided by Mr. Zhang, the most expensive right front headlight assembly in the previous damage assessment document did not appear in the maintenance list.

"Mr. Zhang’s Audi Q7 has a fixed loss of 82,534 yuan. Click on the picture to see a bigger picture."

　　Mr. Zhang felt that the 4S shop was tricky, so he directly called the 400 customer service of FAW Audi manufacturer, and the complaint immediately took effect. The 4S shop then contacted Mr. Zhang to communicate. Mr. Zhang said that during the negotiation, the after-sales staff of the 4S shop said that the most expensive headlight group was genuine and had a customs declaration form, but it was not originally purchased by Audi, which means that the headlights were sub-factory parts. The explanation given by the after-sales staff of the 4S shop is that the original accessories of Audi are very expensive. This statement was subsequently confirmed in the 400 customer service of FAW Audi, saying that the 4S shop has two systems.

"The maintenance fee that Mr. Zhang found on Audi App is 13,863 yuan."

　　Mr. Zhang believes that it is naked fraud for 4S stores to replace the original parts with deputy factory parts. According to Article 55 of the Consumer Protection Law, fraud should be refunded for one and compensated for three. Mr. Zhang filed a claim for compensation with the 4S shop and hoped to get at least 2.5 times the compensation. 4S stores may face hundreds of thousands of penalties for fear of fines from manufacturers, so they seek reconciliation from Mr. Zhang, and hope that Mr. Zhang can cancel the complaints from manufacturers and agree with Mr. Zhang’s demands, saying that it will satisfy Mr. Zhang.

　　Ten days after Mr. Zhang withdrew the lawsuit, the 4S shop changed its tone again, saying that Mr. Zhang’s car was a bus, so it was not suitable for the relevant laws of returning one and losing three. Mr. Zhang said that his car is a personal car, only bought in the name of the company, not a business car.

"Statement given by Mr. Zhang"

　　Later, Mr. Zhang complained to the manufacturer’s 400 customer service again. However, after this complaint, the 4S shop ignored Mr. Zhang’s appeal, and neither the manufacturer’s customer service nor the 4S shop gave any follow-up compensation plan, only saying that the relevant accessories could be replaced. Mr. Zhang said, "In the follow-up, more than a dozen complaint calls were made. The manufacturer was more like a microphone. At first, there was a reply. Later, even the reply was gone, and no substantive problem was solved."

　　Two weeks ago, Mr. Zhang complained about this matter to the Changsha municipal hotline. On November 21, a market supervision administration in Changsha called Mr. Zhang and said that the 4S shop had a requisition, which could prove that the parts replaced for Mr. Zhang were not sub-factory parts. Mr. Zhang said that the regulatory authorities have never called themselves before and have not communicated accordingly. But last Friday, Mr. Zhang received WeChat from the after-sales staff of 4S shop. "The industrial and commercial department has stepped in and will talk to both parties later. Please know!" Mr. Zhang has doubts about the relevant investigation links, because no one has inquired about the victims.

　　At present, the 4S shop only promises to replace the parts that Mr. Zhang has doubts about, but does not give any compensation. Mr. Zhang’s own appeal is that the accessories can be replaced according to the insurance loss. At the same time, the 4S shop should make a refund for fraud.

●　Related practitioners: 4S stores do have hidden rules for purchasing accessories through non-original channels, and consumers will not be informed.

　　Practitioners of relevant 4S stores said that the maintenance of 4S stores must use the original authorized accessories, but at present, some 4S stores do have hidden rules in the industry, that is, one is to order authorized original accessories from formal channels, and the other is to buy accessories from non-original channels. Although the manufacturer explicitly requires that the 4S store must purchase accessories from the manufacturer, the 4S store has accessories purchasing indicators every year, and some indicators are almost the same, or the ordering cycle of the original accessories is too long, the 4S store will consider purchasing from outside, and the 4S store will have a fixed cooperation channel for outsourcing. However, 4S stores usually don’t take the initiative to tell consumers which are original accessories and which are not. In fact, these are all non-compliant. Consumers usually think that 4S stores provide original accessories.

"The picture is only a sign, and has nothing to do with the case."

　　At the same time, when determining the damage, the insurance company will authorize the brand that the accessories and maintenance prices of 4S shops are higher than those of ordinary repair shops, in order to be able to pay the related expenses of original accessories. After all, the price of original accessories is higher, and the use of non-original accessories for 4S shops is nothing more than making more money. It is also non-compliant for a 4S shop to handle the loss-fixing business for an insurance company.

●　Lawyer: In case of suspected consumer fraud, court proceedings will be the best way to obtain strong evidence.

　　Relevant lawyers said that there were many doubts about the operation of Audi 4S shop, and some accessories seen in the fixed loss were not seen in the maintenance list, which was directly suspected of consumer fraud. According to the 4S store, Mr. Zhang’s car is a bus, so the Consumer Protection Law is not applicable, but in fact, the Consumer Protection Law protects all citizens, regardless of public or private, and it does not affect the conclusion of consumer fraud. The company is also a consumer subject. Local legislatures almost unanimously believe that units are also the main body of legislative protection of consumer rights and interests, and the rhetoric of 4S stores obviously does not comply with relevant laws.

"The picture is only a sign, and has nothing to do with the case."

　　Lawyers suggest that if Mr. Zhang goes to relevant departments to obtain evidence, any link in the middle will be wrongly identified by unprofessional people, which will lead to Mr. Zhang’s failure to realize his claim. The shortest way for Mr. Zhang to solve this problem is to defend his rights through court proceedings and let the court intervene, so that the 4S shop as the defendant will have to bear the burden of proof. If the 4S shop continues to commit perjury, it can be directly identified as consumer fraud. According to the relevant provisions of the Consumer Protection Law, the court can directly punish the 4S shop according to law. If the evidence of the 4S shop is true, the court finds that there is no case of replacing the original parts with the deputy parts, and the items on the maintenance list are consistent with the actual risk assessment, then it can be judged that there is no fraud in the 4S shop.

　　According to the relevant provisions of Article 55 of the Law on the Protection of Consumers’ Rights and Interests, if a business operator commits fraud in providing goods or services, it shall increase the compensation for the losses it has suffered according to the requirements of consumers, and the amount of compensation shall be three times the price of the goods purchased by consumers or the cost of receiving services; If the amount of additional compensation is less than 500 yuan, it is 500 yuan. Where there are other provisions in the law, such provisions shall prevail.

"The picture is only a sign, and has nothing to do with the case."

　　Mr. Zhang previously said that there was evidence such as recordings of conversations with employees of 4S stores, but when the court made a judgment, it would combine other evidence to make a judgment in addition to the recorded evidence. Lawyers said that the court, as the main adjudication organ of disputes over civil legal relations, can achieve the most efficient and authoritative one-stop dispute settlement effect, especially when the time is relatively long and the two sides hold their own words, and court litigation is the most effective solution.

●　Write at the end:

　　Although insurance maintenance does not require consumers to pay any fees, it does not mean that it can be careless, and there are often hidden rules of profiteering in the middle. Before maintenance, consumers should confirm the relevant maintenance items, accessories and other information and ask for maintenance documents. Minor defects, major repairs, minor damage, direct replacement of new accessories, and use of non-original accessories may all occur. The quality of using non-original accessories cannot be guaranteed. If you are fully responsible, the cost of going out of danger may also affect the premium for the second year. Therefore, to remind consumers, we should still be vigilant and avoid mistakes in easy-to-neglect links. (Text/car home Qin Chao)

　　In the light snow solar terms, Hangzhou is still bathed in the warm sun. Our traditional culture in China pays attention to "don’t eat from time to time", and now it’s the season to eat cherries, and a new batch of cherries from abroad have been listed in China one after another.

　　"It sold for more than 1,000 yuan a week ago." On November 22nd, after visiting the fruit wholesale market and a number of chain fruit retail stores in Hangzhou, Chao journalists found that the price of cherries was still high, and foodies had to wait to realize the freedom of cherries.

　　The price is "prohibitive"

　　Some merchants did not purchase goods directly.

　　"Up to 3 or 4 boxes a day." When talking about the shipment of their own yellow cherries, the proprietress of Hangma Fruit Store shook her head again and again. "The purchase price is expensive, and I don’t dare to take more every day."

　　Wenhui fruit wholesale market. Reporter Yan Xinei photo

　　In Zhejiang Wenhui Fruit Wholesale Market, the reporter walked down and found that there were 30 or 40 merchants in the whole market, and many merchants only put four or five boxes of cherries in their stores. Some bosses simply didn’t buy any, and the reason was very direct, that is, the price was too high.

　　Subsequently, the reporter went to a number of fruit retail stores in the urban area. Many shopkeepers said that the price of cherries is too expensive now, and fewer people buy them, so they didn’t purchase them. Some chain stores have already started to sell, but the price is "prohibitive".

　　Generally speaking, the bigger the cherries are, the better the quality, such as 14 grams of 4J single fruit, 12 grams of 3J single fruit, 10 grams of 2J single fruit and 8 grams of single J single fruit. For example, a Dayong fruit shop on Tiancheng Road sells cherries with specifications of 3J this year at a retail price of 128 yuan per catty. If it is converted into a box, it should be 600 yuan at least. On the other hand, at a fresh fruit shop opposite, you can see that the signboard of "Fresh Wild Ace, here comes cherries" has been hung at the door, but at present, it is mainly for publicity, and the clerk said that it has not arrived yet.

　　Did Hangzhou Shangchao serve cherries, and what was the price? The reporter opened the APP search of "Box Horse" and "Sam" and found that a catty of cheap 2J cherries is around 100 yuan, and a catty of 3J cherries is around 120 yuan. A kilo of ordinary cherries on the online take-out platform is around 180 yuan.

　　Sea cherries haven’t arrived in Hong Kong yet.

　　It will take two weeks to realize the freedom of cherries.

　　Every November, imported cherries will be listed in China. Chile, Australia and New Zealand are the main producing areas of imported cherries in China. However, at the end of November this year, the long-awaited freedom of cherries came late.

　　"At this time in previous years, the price of cherries in Hangzhou has fallen for a long time. This year is different, and now the price is still running at a high level." Sister Mao, who has been engaged in fruit wholesale for many years in Zhejiang Wenhui Fruit Wholesale Market, told Chao News reporter, "Last year’s cherries were packed in a box of 5 kg, and the general price was more than 300 yuan. Now they are sold in 500 yuan. 4. The quality of 500 yuan is not so good. The better mulberry Tina (cherry variety) is now sold in more than 700 boxes."

　　Jianqiang Fruit in Wenhui Fruit Wholesale Market also sells cherries. "Now 2J black cherries sell a box of 350 yuan, with a box of 5 kg. The specifications of 3J are larger and the price is more than 400 yuan." The proprietress said that this year’s price is indeed higher than the same period of last year, and the price a few days ago is even higher than now. "A few days ago, 5 kg was sold to 1000 yuan. I have dropped some in recent days. "

　　Why is it so expensive? The proprietress of Jianqiang Fruit revealed: "The main reason is that the newly listed cherries are all shipped by air from Chile, and the freight is much more expensive than that by sea. When the cherries shipped by sea arrive in Hong Kong two weeks later, the price of cherries will drop sharply."

　　It is understood that nearly 90% of Chilean cherries are exported to China. Because Chilean cherries shipped by sea arrived in Hong Kong later than last year, the fresh cherries on the Hangzhou market are basically airlifted from Chile.

　　The proprietress estimated the price according to previous years. "After two weeks, the price of 5 kg is more than 200 yuan a box, which can be nearly half cheaper, depending on when the goods arrive."

　　However, the proprietress also said that her goods had just arrived by air on the same day, "fresher than by sea."

　　There are many varieties of cherries.

　　It depends on the variety.

　　"Is there a yellow car?"

　　"Yes, it is expensive, a box of 4 kg and 4 Liang is more than 600 yuan."

　　Near noon, some customers came to the fruit wholesale market to buy yellow cherries, because the owner of the fruit shop offered a higher price. Finally, customers gave up buying yellow cars and bought cheaper mangosteen instead.

　　The customer said helplessly: "The yellow car is crisp and sweet, which is delicious, but the price is too much."

　　The reporter wandered around the market and found that the price of yellow cherries was the most expensive. When asked, the bosses all say that this is mainly because of the variety.

　　According to Mao Jie, an old merchant selling imported cherries, the origin of imported cherries in Hangzhou is mainly Chile, and there are many varieties. The market often sells black cherries such as Santina and Cordia, red cherries such as Brooks, Rabins and yellow cherries such as Rennie.

　　"The taste of cherries depends on the variety, such as Cordia and Santina, which are more delicious than the average variety of black cherries." Sister Mao said that when choosing cherries, you should choose "long legs"-the fruit handle is long and thin. "Under the same freshness, the varieties with long handles will taste better than those with short handles."

　　Reporter Yan Xinei photo

　　She also reminded that if you want to buy high-quality cherries, you should pay attention to the variety of cherries in addition to the 4J label that everyone is familiar with now. "Although you look at the color, the varieties are different, and the price will be much worse. Take yellow cherries as an example. Now the best varieties are sold for more than 800 boxes."
