Original Geely Boyue L interior design new highlights interpretation, emotional interaction or the direction of future model development

Geely BoyueLRecently, the interior design of the car was exposed, and the concept car was adopted. "VIsion SThe interior design idea of "tarburst" has added many new design features to the interior, BoyueLThe interior design of Geely Automobile can be said to be the latest design idea of Geely Automobile, from which we can also see the interior design features of Geely Automobile’s next models. There are also some new details in the details, which are very interesting. Let’s take a look today.

Geely officials say BoyueLThe interior design is "Digital Symphony Technology Aesthetics" design concept, which can also be seen from the name, BoyueLThe interior design takes digitalization, intelligence and technology as the main theme of interior design. Among them, Geely launched the first in the brand13.2Inch straight waterfall large screen, surround emotional light curtain, crystal diamond stopper, headrest sound and other details further highlight BoyueLThe sense of interior technology. Interior color scheme BoyueLYes.2A different scheme, one is brown+Blue "Autumn Field Brown", the other is white+Blue "Winter Snow Mountain White".

In terms of interior materials, a large number of suede materials are used in the car, and the use of a large number of soft materials also enhances the luxury experience of users’ daily cars. With the first-ever wraparound emotional light curtain, it is even more interesting. The wraparound emotional light curtain is these vertical strips of different lengths in the interior, and there are a total of light strips27Group, surround the entire center console and the door panel of the front door. The light strip can present lighting effects such as voiceprint, breathing, and water flow changes. When the vehicle is in different states such as music rhythm, nap mode, voice interaction, and air conditioner linkage, it can present different light effects to realize the user’s "emotional" linkage, so that the machine also presents a certain sense of "emotion". This function is personally preferred. Now many young users have similar lighting designs when building their own study or e-sports room. Adding such a design in the car makes the car have "temperature".

BoyueLcarried on13.2Inch touch multimedia screen with a resolution of1440x1920,It is close to the vertical screen in size.4What is it?3Screen, in terms of pixel density, the clarity should be better, and you need to wait for the real car experience. This is also the first time Geely has used it.13.2Inch size screen, the surface of the screen has been treated with anti-fingerprint (oleophobic coating), anti-reflection coating, and anti-glare film, and the effect under strong light is worth looking forward to. The large screen is pre-installed with Geely’s Galaxy.OSIntelligence systemAIR version (specially adapted)13.2Inch brand new version). The screen can also be followed by10.25Inch full LCD meter and25.6inchAR-HUDHead up display linkage, to achieve three-screen linkage function.

Milky WayOSIt is the mainstream on-board intelligent car system on Geely Automobile. The current mainstream configuration is YikatongE02Chip, match12.3Inch multimedia screen. But BoyueLUsed on13.2Inch multimedia screen, and not surprisingly, it will be powered by Qualcomm Snapdragon.8155The car-grade chip acts as the brain of the car-machine system (Xingyue)LAlso carry8155)So in order to adapt to the new hardware, Geely Automobile developed the GalaxyOS AIR version, compared to the mainstream galaxyOSVersion,AIR version adoptsFReed TOuch lightnessUIDesign (that is, the new system interface design), the use of short URL design in the operation interaction, the user’s commonly used functions are just a click away, improve the user’s efficiency.

BoyueLEquipped with a sound system from HARMAN Infinity. Of course, if there is no accident, this is the top configuration, and it may also be presented in the form of an optional package. There are total sound systems11A speaker, among which the more special is the headrest sound arranged at the driver’s headrest, which can separate the driving signal from the entertainment signal, that is, the music and navigation signals are played separately, so that the music navigation does not interfere with each other. The sound system has three music modes: private, driving and sharing. In recent years, Geely cars have often carriedBOSESound system, HARMAN Infinity audio is generally used by Lynk & Co, so BoyueLThe music experience is still worth looking forward to.

BoyueLIt is not a model with an antibacterial steering wheel. Among other Geely models, the antibacterial steering wheel is already one of the more mature configurations. For example, ColorfulCOOL,JiajiLAnd other models are equipped with antibacterial steering wheels or antibacterial interiors. The antibacterial steering wheel will add nano-silver ions to the material during production. Through the sterilization effect of nano-silver ions, common pathogenic bacteria such as Staphylococcus aureus and Escherichia coli can be killed to protect the health of the occupants. BoyueLThe antibacterial steering wheel is designed with an e-sports handle, which is functional in terms of suppression, sterilization, disinfection, and deodorization. Perhaps its process is different from that of other models.

BoyueLThis time, a newly designed electronic stopper is adopted, which is different from other Geely models. Geely’s current electronic stopper handles still have many shapes, XingyueL,EmgrandSThe aircraft-style stopper on the aircraft, the Jiaji Platinum Edition, the diamond-shaped stopper on the Boyue Asian Games Edition, the ColorfulCOOL,BinruiCOOLUse the Thor Black Block handle etc. onLThe crystal diamond stopper used on the phone is more eye-catching than other stoppers, and the shape is thicker. The inner laser of the stopper is engraved with "Thor Power".logo,It’s still nice.

BoyueLThe seat design on the car adopts a new shape, compared to other Geely models, the BoyueLThe seat design strengthens the waist support and shoulder support, and the sitting feeling is worth looking forward to. The waist support position is made of suede, and the use of fur material can also strengthen the friction at the waist to ensure the driver’s intense driving feeling. Compared with other Geely models, BoyueLAdjustable leg rests are added to the seat, making it easier for users of different heights to find a more suitable posture for them. The seat is equipped with seat suction, heating, memory and other functions in the details, and the functionality is in the past.

BoyueLThe sun visor on has made a unique design, and the sun visor adoptsPCOptical materials can block ultraviolet rays during the day and prevent high beams from facing the car at night. Functionally, it is similar to the design of sunglasses. At present, there are no other models on the market with similar designs, but there are similar sunshade accessories sold in some online stores. But from personal experience, it remains to be seen whether sunglasses visors have any value before drawing conclusions. After all, most users will place special sunglasses in the car, and the effect of some advanced polarized sunglasses will definitely be better than that of sunglasses visors. But taking a step back, the industry must have some avant-garde designs if it wants to upgrade and progress. No matter how many functions these new designs have, it is a brave attempt and exploration.

Nongfu Spring earned 4 billion in the first half of the year, and Zhong returned to the throne of the richest man

Text | Business at a glance, wooden fish

Editing | Xue Xiang

On the evening of August 25, Nongfu Spring released its 2021 semi-annual report.

In the financial report, Nongfu Spring experienced good growth in revenue and net profit in the first half of 2021.

In the first half of the year, Nongfu Spring’s revenue was 15.17 billion yuan, an increase of 31.4% year-on-year; net profit was 4.013 billion yuan, an increase of 40.1% year-on-year; gross profit margin rose from 59.9% in the same period last year to 60.9%.

This is the best growth rate of Nongfu Spring since 2017. For the increase in revenue and net profit, Nongfu Spring said in the financial report that this is mainly due to the increase in the company’s product sales, the change of product structure and the effective control of the cost of PET (the material used in the bottle).

Let’s take a look at the main business segments of Nongfu Spring, including packaged water, tea beverages, energy drinks, juice drinks, and other innovative categories.

The financial report shows that in the first half of the year, the revenue of Nongfu Spring packaged drinking water products was 8.919 billion yuan, an increase of 25.6% year-on-year; the revenue of tea drinks was 2.18 billion yuan, an increase of 36.4% year-on-year; the revenue of functional drinks was 2.004 billion yuan, an increase of 38.4% year-on-year; the revenue of fruit juice drinks was 1.224 billion yuan, an increase of 29.9% year-on-year.

It is worth noting that although the sparkling water of its innovative category in the first half of the year was accused of false propaganda due to its Japanese advertisements, it encountered a marketing "rollover" storm, but it did not hinder the growth of Nongfu Spring related fear of you getting tired. According to the financial report, "other categories" including Nongfu Spring soda, gas-flavored drinks, coffee drinks, plant yogurt and other new products earned 846 million yuan in the first half of 2021, an increase of 86.8% year-on-year. 2. png

 We should also see that the rapid growth of Nongfu Spring’s revenue in the first half of the year was due to the increase in marketing expenses. According to the financial report, Nongfu Spring’s sales and distribution expenses increased by 860 million yuan to 3.554 billion yuan in the first half of the year, an increase of 31.92% year-on-year. This is also the period when Nongfu Spring has invested the highest amount in marketing expenses since 2017.

Let’s take a look at management data again.

The gross profit of Nongfu Spring is amazing. The financial report shows that during the reporting period, the gross profit of Nongfu Spring was 9.241 billion yuan, an increase of 33.7% year-on-year, and the gross profit margin reached 60.9%; the net profit was 4.013 billion yuan, an increase of 40.1% year-on-year, and the net profit margin increased by 1.6 percentage points year-on-year, reaching 26.54%. More than the competitor Master Kong, the unified 30% gross profit margin is nearly twice.

From the financial report, the improvement of Nongfu Spring’s net profit is due to the reduction of Nongfu Spring’s management fees and financial expenses. In the first half of the year, Nongfu Spring’s management fees (administrative expenses) decreased by 5.16%, and financial expenses decreased by 20.69% year-on-year.

3. pngOf course, compared with the bright results of the first half of the year, Nongfu Spring’s performance in the secondary market is very dismal. Since January 8 this year, Nongfu Spring’s share price reached the highest point of HK $67.75 per share, Nongfu Spring has begun to fall all the way. As of August 25, the entire share price has fallen by more than 40%, and the market value has evaporated more than 300 billion Hong Kong dollars. The decline in market value has also caused the price of Nongfu Spring’s helmsman, Zhong Sui, to shrink significantly. From January 8 to the end of June for more than 5 months, Zhong Sui’s worth has evaporated by about 270 billion Hong Kong dollars, which also made him lose the throne of the richest man in Asia and China.

It is reported that as of today’s Hong Kong stock close, Nongfu Spring’s share price fell 2.96% to HK $39.3/share, with a total market value of 441.986 billion Hong Kong dollars. In the Forbes real-time rich list, Zhong Shanyuan ranked second on the Asian rich list with a price of 66.70 billion US dollars and returned to the position of the richest man in China.

After the release of this financial report, the downward trend in the share price of Nongfu Spring may have eased.

Lighting | deep learning empowers spectral imaging

Writing | Huang Longqian

Recently, from the School of Optoelectronics, Zhejiang University Hao Xiang The team of researchers is "Spectral Imaging with Deep Learning"The topic is Lighting: Science & Applications Published a review paper, sorted out the spectral imaging technology based on deep learning, explained the principle and research summary of its various technical routes, and organized the current spectral imaging dataset, outlining the possible future trends and challenges.

First, spectral images

The image we usually see in the display screen is an RGB three-color image, which has three channels of red, green and blue, that is, the color of each pixel is formed by superimposing the three colors of red, green and blue. If the three-color image is expanded to ten colors, hundred colors, and thousand colors, then our control and rendering of the image color will be extremely fine. An image with so many bands is a spectral image (term explanation >): it has more than three bands, which can be thirty or even hundreds.

Figure 1 Schematic diagram of a spectral image composed of 9 bands

The spectral information of a substance can fully reflect its internal physical structure and chemical composition. When there are enough wavelength bands in the image, each part is a spectral curve – reflecting the structural composition of the place. Therefore, the spectral image not only reflects the spatial characteristics of the imaging target, but also contains its structure and composition characteristics. Therefore, in addition to fine image rendering, the key application of spectral images is material composition analysis, which is widely used in remote sensing, medical detection, food detection and other fields.

Second, spectral imaging

Spectral imaging is a combination of imaging technology and spectral detection technology, and the main technical goal is to obtain spectral images. Traditional spectral imaging technology is scanning(Including point scanning, line scanning, band scanning)By constantly moving the spectrometer to obtain the spectrum of each point, a two-dimensional image is finally obtained. This scanning spectral imaging system is bulky and slow, which has been criticized.

Figure 2 Scanning spectral imaging (from left to right, point scan, first scan, and band scan)

With the development of computational optics, computational spectral imaging has become a new spectral imaging method. The method uses some coding to make the hidden spectral information enter the detector in a certain way, and finally uses the optimization algorithm to reconstruct the spectral image. The traditional computational spectral imaging method is iterative. Although it has effectively reduced the size of the system compared with the scanning spectral imaging, it has a great computational burden, often requires several minutes or even hours of iteration, and the reconstruction accuracy is relatively average.

The huge burden of data computing prompts people to think and look for more effective spectral reconstruction algorithms. In recent years, deep learning has developed rapidly, and the powerful pattern recognition and feature extraction capabilities of deep neural networks after good training have been favored by spectral imaging researchers. Deep learning methods have become the object of exploration, and deep learning has gradually empowered spectral imaging.

Methods of deep learning

The process of computational spectral imaging coding sampling system design and spectral image reconstruction, deep learning technology can be applied in every aspect of the process. How to effectively classify these different techniques is a key issue. The review proposes to classify according to the properties of light, that is, the computational spectral imaging system is divided into amplitude coding, phase coding and wavelength coding according to different coding methods.

(1) Amplitude-encoded spectral imaging

Figure 3: The spectral coding process in a coding aperture system

Amplitude-coded spectral imaging is achieved through a coded aperture system(CASSI)Conducted, using coding aperture(Amplitude mask)Amplitude coded spectral imaging based on deep learning replaces the iterative algorithm of compressed sensing recovery with deep neural networks, and performs efficient spectral reconstruction through codec co-optimization, iterative expansion neural networks, and untrained networks.

(2) Phase-encoded spectral imaging

Figure 4: A phase-encoded spectral imaging system

Phase-encoded spectral imaging through diffractive optics(Diffraction Optical Elements, DOE)Phase coding is achieved by designing the two-dimensional height profile of the DOE to achieve specific phase delays at different positions. Phase coding affects different spectral components through Fresnel diffraction, and then by modeling the diffraction process, the original spectral image can be reconstructed by the algorithm. Due to the complexity of diffraction calculation after phase coding, traditional iterative algorithms are difficult to achieve effective recovery of spectral images. This problem has been solved after the emergence of deep learning. At present, the spectral recovery of phase coding is mainly carried out through deep neural networks. Compared with amplitude coding, phase-encoded spectral imaging has the advantages of small light energy loss and compact system.

(3) Wavelength-encoded spectral imaging

Wavelength-encoded spectral imaging directly encodes the image in the spectral dimension and can be performed through optical filters. RGB images can be regarded as a kind of spectral coding. At present, the mainstream wavelength coding methods use existing RGB or design optical filters, and the encoded spectral reconstruction mostly relies on deep learning technology.

Direct spectral reconstruction based on RGB images is a very hot direction. With the NTIRE 2018 and NTIRE 2020 spectral reconstruction competitions, many deep learning technology teams participated, greatly expanding the existing deep learning spectral restoration techniques. The researchers analyzed the RGB spectral reconstruction and filter design spectral reconstruction involved in deep learning, and divided the reconstruction methods into point reconstruction and block reconstruction, so as to introduce each reconstruction method.

Figure 5 Codec Cooperative Design Spectral Imaging Technology [
1] [
[2] (Source: Advanced Theory and Simulations)

Wavelength coding based on custom optical filters is an emerging spectral imaging technology in recent years. By designing wide-spectrum filters, greater coding freedom can be obtained than RGB filters. Combined with effective deep learning technology, compact, fast and accurate spectral recovery can be achieved.

IV. Future Outlook

Based on current deep learning techniques and spectral imaging techniques, the researchers have made some suggestions for the future development of deep learning-based spectral imaging. These include the large-scale and normalization of datasets, and the use of large neural networks(For example Transformers)Introduce additional information such as object categories, solve the problem of layer disappearance in the process of codec collaborative design, and use neural networks architecture search technology.

Jackie Chan visited Taiwan four years later to raise money for poor school children (Photos)



    China News Agency, Taipei, June 18 (Reporters, Xu Xiaoqing, Geng Jun) After four years, the famous artist Jackie Chan visited Taiwan again on the 18th. Jackie Chan, who is Taiwan’s son-in-law, said here that "I am afraid of my hometown, and this trip is a special trip to raise money for poor children in Taiwan."


    At the invitation of TVBS Caring for Taiwan Cultural and Educational Foundation, at 1 pm, Jackie Chan appeared on the 84th floor of the "One? One" building in Taipei to attend the "Baby Our Hope – Jackie Chan Endorsement Fundraising Press Conference". This is Jackie Chan’s second appearance in Taiwan after many years, which has attracted the attention of many media.


    Jackie Chan said that as a Taiwanese son-in-law who married a Taiwanese wife, he was "half Taiwanese." He said that after living in Taiwan for a long time many years ago, he loved to eat Taiwan’s cold noodles and red rice, and he had a deep affection for the streets of Zhongxiao East Road and Dunhua South Road in Taipei, and even the grass and trees. In fact, he has always wanted to do something for Taiwanese children.


    At the press conference, Jackie Chan met face-to-face with poor school children from Taitung, Yunlin, Taipei and other counties. He confessed to the children that "when I was a child, I was similar to you, or even more bitter, and I didn’t have schooling." He encouraged Taiwanese children who received funding to cherish the good environment created by social charity groups, study hard and thrive.


    According to Li Tao, a veteran TVBS host, Jackie Chan is keen to participate in Taiwan’s philanthropy and is an "activist" who talks less and does more. Jackie Chan himself also admitted that he often watches Taiwanese TV programs at home in Hong Kong, especially some news about visiting the poor, hoping to learn about the groups in Taiwan that need urgent care.


    According to reports, Jackie Chan recently learned through a TV news that the football team of Fengli Primary School in the mountainous area of Taitung has been short of funds for a long time. He immediately donated a sum of money to help the caddies buy jerseys and provide travel expenses for the football team to participate in large-scale competitions. This time, Jackie Chan endorsed TVBS charity activities, hoping to raise 60 million NT dollars this year as a bursary for 10,000 poor school children.


    Jackie Chan also revealed that in addition to caring about the physical and mental health of Taiwanese children, he is non-stop mobilizing the Asian entertainment industry to raise funds for the relief of the Wenchuan earthquake. He said that after the Sichuan earthquake, not only Hong Kong people from all walks of life took action, but also Taiwan compatriots did a lot for it. Everyone is very concerned about the earthquake.


    Jackie Chan’s "whirlwind" appearance in Taiwan this time. He called on the media: focus more on children’s charities and less gossip. End

How to sweep the world without sweeping a house? Large spot checks on the official website of car companies

  The executive introduction clicks in empty without a word; the most recent one in the marketing newsletter is still 2010; the website has not been introduced to its own model after reading it; the vertical version is arranged in the title picture with text style news newsletters, and there is no picture for the new general manager. Under the title, it is empty and white. Where have you been, general manager? All kinds of mistakes make people laugh and cry, what happened to the official website of the car company…

  If a person is sloppy and untidy, without paying attention to details, would you like to believe that he is serious, reliable, and trustworthy?

  "People rely on clothes, horses rely on saddles", the official website of a car company, as the most direct way for users to recognize the brand, is it not the face of the company facing consumers?

  In today’s automotive society, automakers with annual sales of hundreds of thousands or millions of vehicles and turnover of tens of billions or hundreds of billions of yuan are all big guys, and it is common to spend millions of yuan on brand activities. But why, more or less, there are such and such mistakes on the official website, and some even make people laugh and cry.

  In the Internet age, the industry talked about Internet thinking every day. Auto e-commerce was also a buzzword of the moment, but the most basic network was a prerequisite for everything…

  Product introduction, enterprise dynamics, service categories, and online interaction with consumers are all functions of the official website, and they are also the most efficient means for users to understand the enterprise.

  Take the two most basic functions of news information and model display, which attract the most attention from users, as an example.

  The author consulted the official websites of 25 industry companies. According to yesterday’s deadline, a total of 403 news articles were released from May to July, and the average company released only 5 news articles per month. Among them, Dongfeng Yueda Kia is the best, publishing a total of 52 news articles, which is about 17 articles per month. Consumers can keep abreast of the latest developments of the company in detail. BMW Brilliance updates are the most lagging. There is no news release from May to July. The most recent one was published on April 15.

  FAW Toyota’s website uses 36 pictures to occupy the center position, which is about the size of the entire screen to display product information. Including model introduction, car purchase discount information, consumer interaction activities, etc., the information basically covers all its models, which is convenient for users to browse and can grasp first-hand information without going to the store. On the contrary, Geely, which has nearly 20 models, has only 4 pictures in the same position, which fails to make full use of the promotion on the official website. And BMW Brilliance is even worse, and the model introduction cannot be found on the homepage…

  Dongfeng Nissan: Where have you been?

  In fact, in terms of page layout and aesthetics, Dongfeng Nissan’s official website can be called exquisite workmanship. A big picture with Xuanyi, Teana, Xuanyi Classic, TIIDA, Qashqai, Sunshine, Liwei Qixiong debuting, Dongfeng Nissan is waiting for you to compare, and it is domineering.

  But when the author clicked on the news center column, he was really shocked. So far in July, there has only been one news release, and the vertical version is arranged as a news bulletin with a title picture and text style. When I saw the new general manager take office, there was suddenly no picture. Under the title "Daiyue Jin Appointed as the New General Manager of Dongfeng Nissan", there was nothing. General Manager, where have you been?

  Similar mistakes have appeared 4 times in the first 22, which is really not right. At least you can’t lose the boss…

  BYD: Missed to meet customer service classmates

  New energy vehicles are currently a hot topic, with news such as exemption from purchase tax, elimination of local protection, and unified fast charging of national standards continuing recently.

  Although the location of the news center on BYD’s official website was obvious, there was only one news item for each of the three months of May, June, and July, which was really pitiful. Old Wang also knew how to praise his own melons. BYD, which had always claimed to be in the leading position of new cars, should also be at the forefront of promotion.

  However, the manufacturer’s activities and preferential promotion columns are frequently updated and rich in content, allowing consumers to keep abreast of the latest corporate information.

  But when I opened the online car purchase column and watched the "BYD e-purchase anniversary celebration" event, the customer service who was specially prompted that you must contact in advance before payment could not display the corresponding information after clicking, which made the author feel ashamed. It’s a good event, why is the most critical step stuck?

  Finally, I couldn’t help but shout. As of 5:00 am on July 24th, my companions had all fallen asleep, and Xiao Ai, who was still fighting at night, still had no chance to meet at this moment…

  Ford: Executives, where are you?

  Ford’s website was simple and clean, and the page settings were quite standard. Under the News Center column, the setting of the "Reporter Zone" was unique and unique in this reading of the official website.

  Corporate dynamics is a daily compulsory course for every media teacher. Is this project designed for the release of hot topics in the enterprise? I just wanted to like it, but I almost flashed my waist when I didn’t think about it… The author was surprised to find that the sub-column, "Introduction to senior executives of the company", was blank after clicking on it, and there was not a word. Executives, where are you? "If I knew this earlier, why did I have to start", there is nothing, and why waste this column on emotions…

  Return to the homepage, the bottom row of navigation bar. There are several sub-sections under the Client Server, used cars, and news center columns, but there is nothing under Ford Technology. Click to browse the secondary page, and it can be seen that it is divided into four aspects: fuel economy, safety performance, dynamic driving, and easy control. Since there are, why can’t it be displayed on the homepage to facilitate users to choose their favorite areas? Details, or details.

  Dongfeng Citroen: Fork, are you a fork or not?

  It has to be said that Dongxue’s official website design is the most unique one.

  Magazine page-like promotional graphics are novel in style, with horizontal dragging left and right. The 18 images clearly display the latest dynamic information of the enterprise.

  Under the News and Events column, the "Test drive the champion model or participate in WeChat interaction, that is, have the opportunity to win the World Cup surprise package" activity displayed in the first position reminded the author of the earlier days of the night battle, so click to view the details.

  The first thing that came into view was the pop-up window of the winning list, which was very envious. Although I didn’t know about this event earlier to try my luck, surprises always came unexpectedly. When I tried to turn off the pop-up window, Fork Fork Jun got angry, eh? Can’t turn it off… Although the event ended on the 14th of this month, you can’t be so naughty…

  When a colleague tested it on his computer, we were convinced that he was really not a fork! He just looked similar and looked the same…

  BMW Brilliance: What did you do last March?

  Simplicity and cleanliness are the first impressions that the official website page of BMW Brilliance gave me. But after a cursory browsing, I quickly discovered its biggest feature. Hey, there is no car?

  As the official website of a luxury car brand, BMW has continued its trend-setting characteristics and is at the forefront of fashion. It is the only company on the official website of this statistics that cannot see any product information on the homepage.

  You can only see the product production information from 2003 to 2009 on the company information – products and operations – model overview page. At the bottom of the homepage, click the links of BMW China and authorized dealers to see the relevant product information on the jump page.

  In addition, in terms of news release, BMW Brilliance is also the only company that has not released a news release in May, June, and July. The most recent one dates back to April 15.

  FAW Toyota: 36 Big Pictures Let You See Enough at Once

  "1, 2, 3, 4, 5, 6… 35, 36!" There were actually 36 display pictures of FAW Toyota’s central area, which was much more generous than the other "cheapskates" who only had 3 or 4 pictures.

  Corolla, Vios, RAV4, Crown, Corolla Full Interpretation, Latest Financial Services Solution, Lander Cool Luze, Prado Self-Driving Tour Recruitment, Prius, 86 Zero Distance…

  It includes model introduction, car purchase discount information, consumer interaction activities, etc., basically covering all its models. Users can easily browse and gain first-hand information without visiting the store.

  The layout doesn’t cost money, and it’s not how you want to organize it!

  Great Wall: Online scoring, whether it is good or not, the user has the final say

  Auto e-commerce is a buzzword, but at the moment, there are really few people who are in full swing on their official website, including Great Wall Motors. Just like the dazzling sales performance, the official website of the Haval brand also made my eyes really brighten.

  The most attractive thing for the author is the activity page for ordering Haval H2 online. There is a 360 ° product static display area that integrates appearance and interior. Users can freely choose the full picture of the interior and exterior of the vehicle, including 13 spray paint colors and 8 interior colors. You can control all the information of the model without leaving home.

  In addition, the most outstanding part of the column design is also the only one among all websites. Users can rate products online. Including space, power, control, fuel consumption, comfort, appearance, and interior seven aspects, with a maximum score of 5 and a minimum score of 1.

  At the same time, users can also write a comment of at least 30 words, together with the above scoring items, which will be displayed on Haval’s official website in real time. It can be said that whether it is good or not, the user has the final say. (Reporter, Liu Ye)
