Haval big dog

Dealer’s quotation: 10.59-14.19 million

Manufacturer’s guide price: 11.99-15.59 million.

One disadvantage of the owner:Generally speaking, this car is still very good, but there are always some annoying flaws. The smell in the car can be ignored. After all, new cars are like this, but to talk about the noise problem, the noise of the engine and the poor sound insulation of the interior lead to the noise inside the car!

Owner 2 Disadvantages:What I’m not satisfied with is that the tire noise is obvious, because the tread is wide, and the friction with the road surface is obvious. At low speed, it has little effect, so at high speed, it is a little bit. If this can be improved, my border grazing will be more perfect.

Three shortcomings of the owner:The sound insulation effect is average. When you step on the accelerator, you can feel the roar of the engine is a bit loud, and then the high-speed wind noise and tire noise are still quite obvious, which also affects a certain driving experience, but overall it is quite satisfactory. After all, it is quite good at this price.

Four shortcomings of the owner:I just feel that this central control car still has a lot of room for improvement, the response speed is really slow, and ergonomics is not very good.

Five shortcomings of the owner:The smell of the new car has not been completely eliminated. I have read many methods to eliminate the smell on the Internet, and I have used them, but the effect is not so good.

Six shortcomings of the owner:The disadvantage is that the steering wheel will make abnormal noise not long after the new car, especially when it is cold at night, and it will creak loudly, and it will disappear after a while. Keyless door opening is not very effective most of the time, which is a big problem.

Seven shortcomings of the owner:The dissatisfaction is that the new car smells, and there is sound insulation. If the speed is fast, some noise can still be heard in the car.

Eight disadvantages of the owner:I think the smell inside the car is quite strong, maybe because of the new car. Generally, when I drive, I will lower the window from time to time to change the air inside.

Owner’s nine shortcomings:The Haval Big Dog and Horse Dog version I chose can be said to have everything, so there are really not many short boards. If I have to say something unsatisfactory, it is because the model has a high center of gravity. The height of this trunk is a bit high, and it is a bit inconvenient to take an enlarged piece or a heavy suitcase.

Ten shortcomings of the owner:I haven’t been picking up the car for a long time, and I don’t have much experience with the trendy hard-core SUV Haval Big Dog. After all, the new car is still in the running-in period, and there are not many requirements for buying a car. The trunk space is slightly small. When I see a rider vomiting, my personal experience is not bad.

On March 29th, 2024 Huanxin was listed. As an annual redesigned model, the new car will be upgraded with new color matching and intelligent configuration. However, in the face of Xiaomi’s aggressive attitude, how many chances can Aouita 12 have after the change?

As far as the price is concerned, the 2024 Aouita 12 has launched four models, the price range is 265,800-400,800 yuan, and the overall price is about 60,000 higher than that of the popular one. However, from the car purchase policy, except for the newly-added 700 three-laser rear-drive intelligent version, all other models can enjoy the discount of 5,000 yuan deposit deducting 27,000 yuan, which is really attractive.

From the product point of view, the new car, as an annual redesigned model, naturally has not changed much in terms of face value. It continues the design concept of the current "Future Aesthetics" vehicle, with a simple closed grille and curved belts on both sides, and then it is integrated with triangular headlights, which not only emphasizes the sense of integrity, but also has a strong sci-fi charm.

In addition, with the blessing of future aesthetic design, the car has a body size of 5020/1999/1460(1450)mm and a wheelbase of 3020mm, while the axle length ratio of 0.61, the width-height ratio of 1.38, and the wheel height ratio of 0.514 are combined. Moreover, the new car has introduced a new appearance color of Hui Jin, just like the "chameleon" paint surface, which can show the effect of "floating gold" at a specific angle.

Arriving in the car, the new car adopts the minimalist design concept of Gentle Tech, and the panoramic digital encircling induction cockpit is full of the scientific sense of the new car. 35.4-inch 4K panoramic widescreen, 15.6-inch central control screen equipped with HarmonyOS Huawei HarmonyOS car system on both sides, plus double zero-gravity seats in the front row as standard, and listening to the panoramic sound field of CST coaxial speakers, upgrade the luxury car experience from all dimensions of vision, hearing and touch.

Seeing this, you may already feel that this has not changed much, no! This rejuvenation is actually an improvement in intelligence and security systems. First of all, it is intelligent. The new car comes standard with 3 laser radars and 29 intelligent driving sensors, and is equipped with Huawei’s latest advanced intelligent driving HUAWEI ADS 2.0. In addition, starting from March 28th, Aouita 12 will open the NCA for smart driving, which does not rely on high-precision maps, so as to truly achieve nationwide opening. At the same time, a number of functions are optimized through OTA, including tidal lane and bus lanes, and a new lateral obstacle anti-collision system (LOCP) is added to further enhance people’s intelligent travel safety.

In terms of safety, Aouita 12 adopts ultra-high-strength steel-aluminum hybrid cage body in passive safety, with aviation-grade aluminum and high-strength steel accounting for more than 80%, and has 19 intelligent active safety configurations, and is equipped with 3 laser radars and a general obstacle perception network to realize 360-degree surrounding collision protection. In addition, in order to protect the battery safety, the new car adopts the Contemporary Amperex Technology Co., Limited customized H-type with high-strength 6 series aluminum alloy battery protection case.

On the power level, the maximum power of the 2024 Aouita 12 single-motor model is 313 HP, and the CLTC cruising range is 700km；; The four-wheel drive model is equipped with Huawei DriveONE dual-motor system, with a total power of 578 HP and a CLTC cruising range of 650km. The battery pack has a capacity of 94.5kWh and supports super fast charging. In addition, the new car is also equipped with an air suspension system that can realize active damping adjustment and has the functions of 45mm stroke height adaptive adjustment.

I have to say that the upgrade of Aouita 12 seems small, but in fact, it has greatly improved its intelligence and safety, which will not only consolidate the stronger product strength of its peers, but also give consumers a unique travel and life experience. In the face of the strong invasion of Xiaomi SU7, the new car backed by Chang ‘an, Contemporary Amperex Technology Co., Limited and Huawei is obviously full of confidence and fearless.

　　When the "data visualization" full of science and technology meets the classical Tang poetry and Song poetry, what kind of spark will it spark?

　　Recently, a group of visual data works, Song Ci, Where to Draw the World (hereinafter referred to as Song Ci) and Tang Nv Poets Group (hereinafter referred to as Tang Poetry), have been screened in the circle of friends. The work was completed in half a year by the State Key Laboratory of CAD&CG of Zhejiang University and the Data and News Department of Xinhuanet.

　　The team analyzed 55,000 Tang poems and 21,000 Song poems, and interpreted classical Tang poems and Song poems with big data technology, and unexpectedly found many hidden information.

　　Big data display

　　The place where Su Dongpo went the most was Hangzhou.

　　What does this work look like? Qianbao reporter opened the web version of Song Ci.

　　There are many blank spaces, ink illustrations and elegant color matching style. The style of this work is "close to landscape painting as a whole".

　　It is understood that "Song Ci" takes "Song Ci" as a sample. In order to complete this interpretation, the team analyzed nearly 21,000 ci poems, nearly 1,330 poets and nearly 1,300 epigrams. The basis of the works of Tang Poetry is the data analysis of 55,000 Tang poems.

　　The reporter observed that the web version of Song Ci is composed of Shi Kongtu linked by the poet’s trace map and the life map of the year, as well as the cloud map, image emotion map and prosodic map of Song Ci.

　　In the chronological life map, the reporter selected the broken line representing "Su Shi". According to the diagram, a broken line of "first leveling, then rising and leveling" was displayed, which tried to reflect the ups and downs of Su Shi’s career.

　　On the track map linked with the life map, brown points with different sizes appear synchronously on the map, which are connected by lines, and the size of each point is determined by the number of times Su Shi set foot. This shows the trajectory of Su Shi’s life. From the point line diagram, Su Shi’s footprints are almost all over the territory of the Song Dynasty. Among them, the biggest place is Hangzhou City, which shows that Hangzhou is the place he visits most.

　　The word "east wind"

　　It appeared 1264 times in Song Ci.

　　With the drop-down of the page, what comes into view is the "cloud picture of words" in Song Ci. According to the analysis of the number of words used in Song Ci, the more times they are used, the bigger the font size, the darker the color and the more centered the position. The reporter saw that the word in the middle was "Dongfeng", which was used 1264 times. Followed by "where", it was used 1157 times. The third place is "human world", which appeared 1061 times in Song Ci.

　　"We used to understand the poems of the Song Dynasty and the Tang Dynasty, and more of them were understood and appreciated separately. This study allows us to find the hidden information behind the poems from the big data level." Theway, design director of the State Key Laboratory of CAD&CG of Zhejiang University, told Qianbao reporter.

　　The research lasted for half a year, and the works of Song Ci and Tang Poetry produced by Zhejiang University team and Xinhua News Department were all presented in the form of web pages, which contained quite rich information. Among them, the most informative and complicated work is Song Ci.

　　"In the media industry, such mature visual data news works on traditional cultural themes are still rare." Theway said that this is also the first attempt by the visualization team of Zhejiang University.

　　The poet mentioned "wine" in his works.

　　Half is thinking, 30% is happy.

　　The team not only analyzed the superficial information of the text of Song Ci, but also deeply explored the image meaning expressed by Song Ci and integrated it into an image emotion map.

　　30 common words such as "moon" and "wine" are selected in the image emotion map, represented by 24 prolific poets such as Su Shi and Li Qingzhao. Through the analysis of big data, the emotions expressed by these image words are obtained, and the emotions are divided into five types — — "Think about emotions", and then use pie charts to show the proportion of different emotions expressed by various words.

　　For example, when poets write "wine", nearly half of the images they want to express are nostalgia and thinking. Lu You wrote "Red Crispy Hands, Huangteng Wine", or Yan Shu wrote "A new song and a glass of wine, the weather was old last year", all of which are reminiscing about old friends and thinking about life. There are nearly 30%, which is similar to Zhu Dunru’s "a cup of wine is full every day, and flowers bloom in the small garden".

　　Then, how did big data technology observe the poet’s mood at that time from the lines of Song Ci?

　　First of all, the team needs to sort out the typical images that basically only represent a certain emotion. Theway said that in order to be more accurate, the team specially invited Dr. Hu Qiuyan from Zhejiang University College of Literature to check.

　　Pan Rusheng, who is in charge of data analysis and front-end development, told reporters that they will use big data to analyze the context, calculate the probability that the word belongs to a certain emotion according to typical images, and get the emotion that the poet is most likely to express.

　　To put it simply, for example, the poet Zhang Zai wrote in "The Old Cypress Courtyard of Xinglong Temple": "The peony blossoms in the south and the peony blossoms in the north, and the young people look for fragrance several times. Only the old cypress tree in your family seems to have never come. " Among them, "pine and cypress" expresses an emotion of "remembering". In the context, it can be concluded that what "Peony" and "Spring Breeze" want to convey is also "thinking".

　　Through visual data presentation

　　Make Tang poetry and Song poetry truly popular and easy to understand

　　When asked about the difficulty of this research, Theway first mentioned the choice of charts. In order to find the most suitable data presentation, many charts are easy to draft.

　　Appropriate charts should not only be beautiful, but also cover the information that needs to be presented. At the same time, they should be intuitive and interact with readers smoothly, which really makes the team spend a lot of time. According to Theway, the team tried to use the view of "small mountain peak" to express the cadence of words, but considering that the overlapping of images affected the impression and was not conducive to the placement of imagery images, they finally gave up.

　　"People are visual, and the visual form of popular science means can make obscure ancient poems easy to understand, and let popular science get rid of preaching or boring stereotypes, thus playing a role in promoting traditional culture." Chen Wei, deputy dean of the School of Computer Science and Technology of Zhejiang University, said.

　　The orientation of this research is popular science, so the object of analysis is mainly the most basic content of Tang poetry and Song poetry. Theway said: "This product is not made to draw a certain conclusion, but to provide people with an interesting tool to explore Tang poetry and Song poetry." Therefore, more interesting conclusions remain to be discovered by readers.
