From January 1, 2025, China will adjust the tariff rate of some commodities.

Expanding domestic demand and promoting high-level opening to the outside world
From January 1, 2025, China will adjust the tariff rate of some commodities.

A few days ago, the State Council Customs Tariff Commission issued the "Tariff Adjustment Plan for 2025" (hereinafter referred to as the "Plan"). Guided by Socialism with Chinese characteristics Thought of the Supreme Leader in the New Era, the Plan thoroughly implements the spirit of the 20th National Congress of the Communist Party of China and the Second and Third Plenary Sessions of the 20th Central Committee, adheres to the general tone of striving for progress while maintaining stability, expands independent opening and unilateral opening in an orderly manner, and adjusts the import tariff rates and tax items of some commodities. The implementation of the "Program" from January 1, 2025 will help increase the import of high-quality products, expand domestic demand, promote high-level opening up, and solidly promote high-quality development.

In order to enhance the linkage effect of two resources in the domestic and international markets, in 2025, a provisional import tariff rate lower than the MFN tariff rate will be imposed on 935 commodities. First, support scientific and technological innovation to lead the development of new quality productivity, and reduce import tariffs on automatic gearboxes of special-purpose vehicles such as cycloolefin polymers, ethylene-vinyl alcohol copolymers, fire engines and emergency repair vehicles. The second is to protect and improve people’s livelihood in development, and reduce import tariffs on sodium zirconium silicate, virus vectors for CAR-T tumor therapy, and nickel-titanium alloy wires for surgical implantation. The third is to promote green and low-carbon development and reduce import tariffs on ethane and some recycled copper and aluminum raw materials. In addition, according to the domestic industrial development and changes in supply and demand, within the scope of China’s commitment to join the World Trade Organization, the import tariffs on some commodities such as syrup and sugar-containing premixed powder, vinyl chloride and battery separators will be increased.

In order to expand the global network of high-standard free trade zones, in 2025, some imported goods originating in 34 countries or regions under 24 free trade agreements and preferential trade arrangements will be subject to agreed tax rates. Among them, the China-Maldives Free Trade Agreement came into effect on January 1, 2025 and implemented tax reduction. After the final tax reduction is completed in the future, nearly 96% of the tax items of both sides will achieve zero tariff.

In order to help the least developed countries develop and achieve mutual benefit and win-win, in 2025, we will continue to give 100% tariff treatment to the products of the least developed countries that have established diplomatic relations with China. At the same time, we will continue to implement preferential tax rates on some imported goods originating in Bangladesh, Laos, Cambodia and Myanmar in accordance with the Asia-Pacific Trade Agreement and the exchange of letters between China and relevant ASEAN member governments.

In order to serve the development of the industry and the progress of science and technology, in 2025, domestic subheadings such as pure electric passenger cars, canned Pleurotus eryngii, spodumene and ethane will be added, and the expression of tax items such as coconut juice and made feed additives will be optimized. After adjustment, the total number of tariff items is 8960. At the same time, in order to promote the scientific and standardized tariff system, in 2025, domestic subheadings such as dried laver, carburettor and injection molding machine will be added, and the expression of domestic subheadings such as liquor, wood activated carbon and thermal printer will be optimized.

Huaxia film Hai Cheng Zhao

Promote the transformation of Huaxia film from distribution service to copyright company



Hai Cheng Zhao, Party Secretary and Chairman of Huaxia Film, couldn’t hide his excitement when he revealed to Lan Yu the plan and strategic layout of the transformation of Huaxia Film. As a distribution service company, Huaxia films have achieved fruitful results, but they still have new enthusiasm and are determined to set their sights on the whole film industry chain and take a solid step in production. The series of films directed by Zheng He’s Journey to the Western Seas will be an important position for China’s transformation.

Light-chasing animation in Yuzhou

Team China tells the story of China well.



In the light-chasing animation, Lan Yu was pleasantly surprised to find many letters and gifts sent by fans. Their sincere words encouraged all the staff of light-chasing to move on. In fact, the production of animated films requires a lot of time and energy. One second of beautiful pictures may be followed by more than ten hours of continuous work, but fortunately, every second presented on the big screen is watched enthusiastically by fans.



This craftsman spirit and silent tacit understanding with fans have kept the pursuit of light high-yield. Last summer, the pursuit of light set off a movie-watching frenzy, but it was too late to stop. I was still nervously preparing for the next few works. This year’s Tanabata is about to meet the audience with a comedy love movie, which will be a creative story about classic legends.



The presentation of China traditional culture and a new interpretation of the stories familiar to the audience are the key points of the light-chasing animation creation. Next year, animated films will also be released, and it is planned to be released next summer vacation. After Three Wan Li in Chang ‘an, the creation of The Three Kingdoms Part I: Fighting for Luoyang, the second part of the "New Culture" series, has also been put on the agenda, and it is planned to be released in the summer of 2026. One step at a time, the pace of chasing light animation "chasing light" will never stop.

Yitong making Chen Sicheng

Creators must take the initiative to seek "change"



Talking to Chen Sicheng, Lan Yu sensed his enthusiasm as a creator. It’s just ten years since the film version was released this year. In the past ten years, Chen Sicheng, as a film director, has launched many "explosions", but he still explores various possibilities of film shooting. Seeking "change" and seeking a breakthrough on his own initiative is, in his view, what the creator must accomplish. While he is creating, sometimes he is still groping, but this uncertainty just stimulates him, and in his second decade as a director, he is thoroughly remoulded.



As the operator of a film company, Chen Sicheng has a more overall and macro perspective. He is willing to help the film to complete the creation in different capacities, and also plans the in-depth development of multiple IPS. For example, he revealed that "manslaughter 3" will be an original script. In addition to the return of the leading actor, more new actors will join.



At the same time, Chen Sicheng merged his identity as an operator and a creator, set up a later company and provided systematic services, which was a business behavior and also hoped to provide more convenient and free space for creation. Multiple identities converge on Chen Sicheng, closely surrounding the core, and still remain the purest love for film art.

Guangxian Communication Wang Changtian

Help China’s film industrialization development.



If we use two key words to summarize the current situation of light media, the first is pluralism, just like the ubiquitous spectrum and color bars in the base camp of light, from animated films that have made brilliant achievements to realistic films and youth films with specific social influence, light is still trying to expand the content of various fields. Wang Changtian, chairman of Light Media, revealed that after waiting for the film, they will start new cooperation with the director.



In the "mythical universe" that animation film fans are looking forward to, the light also has "big moves", and more than 20 films will be released one after another. Light is still participating in the China Film World Project in Yangzhou, trying to provide assistance for the industrialization of China films. They are ambitious and more confident that they can blossom in an all-round way.



The second key word of light media is youth. Actors such as,,,, and have all completed their debut in the light, and have also become emerging high-quality newcomers. At the same time, the light not only actively promotes the first works directed by many newcomers, but also internally has the "321 Project" to train 30 producers, 20 screenwriters and 10 directors. Boiling fresh blood and a sense of mission to the film will help the light go further.

Jaco, Maoyan Entertainment

The high-quality development of movies is inseparable from the diversified ecological environment.



In early spring, Lan Yu followed Jaco, president of Cat’s Eye Pictures, to experience the day’s work arrangement of film practitioners. The first job is the job interview for new employees, which not only represents the addition of fresh blood, but also reflects Cat’s Eye’s sense of responsibility for talent cultivation in the film and television industry. This year, they will launch the Guan Peisheng program to provide employment opportunities for more young people who love movies, and also to transport more talents to the industry.



The second job is the announcement and resumption meeting of the Spring Festival films. In the past year, Cat’s Eye cooperated with the film channel to carry out a series of live media activities, which not only helped the whole industry, but also innovated the mode of film promotion.



The third job is a discussion with the creator. Cat’s Eye has a direct dialogue with the creator to provide services for the new film. At the same time, Cat’s Eye also directly contributes to the industry in content production. Taking stock of the next new film reserve of Cat’s Eye, Jaco revealed that Jiangyuan Lane will be a highly completed work. The director spent seven years on this film and polished a detail on the shooting scene many times. In addition to being mysterious for seven years, it is also expected to make a heavy debut in the second half of this year, bringing surprises to the audience.


In addition, Cat’s Eye will also test the water to independently develop animated films and meet the audience in succession. Cat’s eyes, sensitive to data, are the first to catch the signal of spring in the air of China movies. They will also catch up with spring with practical actions and reach a bright future with the whole industry.

Chen Zhixi, WANDA CINEMAS

Tap the charm of light and shadow to make young people fall in love with movies



The place where Lan Yu talked with Chen Zhixi was Wanda Studios, where Chen Zhixi started a new chapter in her work and was also a "blessed land" that accompanied her whole career. Wanda has 916 cinemas all over the country, connecting audiences all over the country, and it is also a place where every filmmaker meets and communicates with audiences. Since childhood, Chen Zhixi has a deep affection for the cinema, and she also hopes that through her own actions, more people will enter the cinema and fall in love with movies. To this end, she hopes to innovate the cinema format and attract young audiences.



This goal also requires front-end content delivery, which is an area that Chen Zhixi has always been very familiar with and good at. She has accompanied many filmmakers to become mature creators from their debut. In her view, selecting projects means selecting people. Only by finding the characteristics of each director and discovering their talents can we achieve high-quality works.



Next, Wanda, led by Chen Zhixi, will send more talents and fill the market with more content.

Shanghai Film Group Wang Jianer

Developing new quality productivity and renewing IP content



The last time Lan Yu talked with Wang Jianer, the head of Shanghai Film Group, "Fanhua" was still to be released, and now the splendor of "Fanhua" has been appreciated by countless audiences. In the past year, Shanghai Film Co., Ltd. handed over other works, which are accumulated over the years. Shanghai Film Co., Ltd. has full patience in creation and production.

Starting from 75,800 yuan, the five-seat version of Wuling Binguo SUV was officially launched.

On September 20th, the five-seat SUV was officially launched. The new car is available in three configurations: 330km, 401km and 510km, and the price range is 75,800-95,800 yuan.

Bingo PLUS upgraded to Bingo SUV.

Everyone should have seen that the five-seat version of Bingo SUV was upgraded from Bingo PLUS, and the core change was from four to five. In addition, the new car has added a 330km version, which means that the threshold for buying this car is lower.

The new car has added two new car colors, milk coffee white and glass red, plus the previous storm gray and aurora green, and there are four color schemes for everyone to choose from. The interior is available in two interior colors: empty green and warm sand white.

In addition, the new car has all adjustments in the chassis and NVH, which further improves the comfort of this car.

It is necessary to upgrade five seats.

It is very necessary to adjust the Wuling Bingo SUV to five seats, because the car itself is not small and can be made into a five-seat version. Through investigation, Wuling also found that more people would choose five seats than four seats. In addition, competitors BYD and Geely are also five-seaters, so it is a key adjustment to upgrade Wuling Bingo SUV to five-seater, so that it can be in an equal position with competitors.

In terms of battery life, only 401km and 510km were provided before. Wuling hopes to win the favor of consumers through longer battery life, but its starting price is not low because of its longer battery life. However, a large number of consumers buy this car if they take a fancy to its large space. In fact, the daily life can be slightly shorter without affecting it. In order to meet the needs of these consumers, Wuling has added a 330km version, and the entry price is lower.

We also saw BYD Yuan UP, which only provides 301km and 401km battery life, but does not provide a 500km version, because the price of its 301km version is 96,800 yuan. If the 500km version is introduced, the price will overlap. After Wuling added a 330km version, the entry price dropped to 75,800 yuan, which was more than 20,000 yuan lower than BYD UP, and the cost performance was much higher.

Large seating space and large storage space.

Although Wuling Binguo SUV is a small SUV, it has a lot of space. The new car is built on the platform of Tianyu Architecture -M, with the length, width and height of 4090*1720*1575mm and the wheelbase of 2610 mm. The long wheelbase makes the distance between two rows of seats reach 882mm, and the lateral space utilization rate is as high as 78.4%.

The trunk is designed to be sunken. After the backrest of the rear seat is leveled, a large trunk space of 1,450 L can be formed, which fully meets the needs of users for more loading scenes. There are 23 storage compartments in the car, so everyone has enough storage space when the family travels.

Strong power and long battery life

In terms of power, the five-seat version of Wuling Binguo SUV is equipped with a 75kW three-in-one water-cooled flat wire motor, with a maximum torque of 180N·m, and it takes only 3.7s to accelerate the start at 0-50 km/h. The starting speed of electric vehicles is very fast, so it will be very cool to use cars in cities. In addition, its top speed can reach 140km/h, and it is not a big problem to run at high speed.

The battery life is 330km, 401km and 510km, all of which correspond to 31.9kWh, 37.9kWh and 50.6kWh respectively. The power consumption per 100 kilometers is only 10.1kW·h, and the operating cost per 100 kilometers is less than that of 6 yuan. In addition, all new cars are equipped with fast charging as standard, and the SOC from 30% to 80% takes only 30-35 minutes.

After the Wuling Bingo SUV has been upgraded by five seats and added a 330km version with lower battery life, I have a hunch that its sales will be greatly improved, because the upgrade points are what everyone wants, what do you think?

Many netizens spit out her "tearing style" and described her as a bangs moth. The overall shape seems to lack beauty. Some people even think that this combination exposes her body defects.

This model was interpreted as a bold attempt, but it received a polarized evaluation. Some netizens believe that this is a breakthrough in fashion, a challenge to traditional aesthetics, and shows Zhao Lusi’s attitude of boldly trying new styles. However, some people think that this collocation is too avant-garde, looks a bit "too shabby", is not coordinated enough, and does not conform to her always fresh and natural image.

Especially the tattered black socks were criticized by some netizens for being too messy, which made the whole look a bit untidy. It was even pointed out that such clothes exposed the defects of Zhao Lusi’s figure and became the focus of discussion among netizens. Although this fashion experiment has caused controversy, some fans think that Zhao Lusi dares to challenge his image and pursue an unusual sense of fashion. This brave attitude is worth encouraging.

In order to suppress HarmonyOS’s bad moves, Google is anxious

Android (Android) platform .apk File, you should be familiar with? All software and applications used by Android users are application packages based on. apk.

Through the. apk file, Android users can freely share the installation package on other platforms. You don’t need an app store, as long as you can download it, you can install it.

but .apk The existence of the installation package can get rid of the bondage of the application store.Download, share and install freely.The required software, not to mention the convenience.

Similarly,Huawei HarmonyOS OS At present, it is in the initial stage, and the development team also uses the Android compatibility layer considering the development cost, difficulty and learning cost of native applications.

At present, the software environment in HarmonyOS is dominated by Android applications.. It is a good thing to be compatible first and then independent, which is beyond reproach. Otherwise, it will become "a clever woman can’t cook without rice."

* Win10 Mobile died in the dilemma of no software available.

Recently, when Guo was browsing the Android developer’s documentation, he suddenly found such a thing:The application package will be updated to. aab format, and. apk may become history in the future.

And this iteration of the application package format update, the fruit feels like "the meaning of drunkenness is not in the wine", which is likely to beSuppress HarmonyOS OS software environment.

What is the specific situation? Listen to me slowly.

What is aab?

. aab is a brand-new application publishing format for Android, and its full name is:Android App Bundle , its status is consistent with. apk.

This time,Google App StoreIt is announced that starting from August 2021, applications that require new Google Play must use Android App Bundle.

So the new format What are the advantages of aab? What are the disadvantages? Why do you say it may be to suppress HarmonyOS OS? ?

Before I explain, let’s take a look at Android. . apk subcontracting extension and splitpk.

Subcontracting expansion

In domestic App stores, when people download large-scale apps, such as games.

Usually, you need to download an. apk installation package with a capacity of more than 1 g.

But this large-capacity. apk is in the Google App Store.Not allowed,Instead, use the .obb Files-also known as APK extension file.

use apk + obb The purpose is to optimize the user’s transmission and download, and the developer’s maintenance experience.

For example, WeChat installed by everyone (The package name is: com.tencent.mm) domestic version, the installation directory will be in /data/app/ Down.

And the Google version still needs to be /Android/obb/ The directory stores the. obb data package of WeChat, which is necessary.Missing or mismatch will lead to application running problems.

Similarly, large-scale game software also uses this scheme, as shown in the picture, the. obb expansion package of League of Legends Mobile Games is being downloaded.

Split APK

The above introductionSubcontracting expansion,It solves the problem that users and developers deal with large-scale applications.

And in essence, the efficiency and speed of the application.Not much improvement..

Therefore, Google introduced Split APK Concept.

Simply put, before installation, the user’s hardware configuration will be automatically detected, and thenInstall the application in the form of multiple. apk..

As the picture shows the installation directory of YouTube client, it can be seen that Split APK is adopted.

Among them, the file name suffix xxhdpi is 1080P resolution.Layout file, zh is simplified Chinese.Resource file, arm64_v8a is 64-bit processor architecture lib library file.

In this way, it is convenient for developers to maintain and improves the user’s experience of downloading, installing and running efficiency.But it also brings a series of problems.

Permission collection

At present, users can’t directly extract and install applications using Split APK, and they all need to use third-party tools to back up and install them.

This means that it will be more and more difficult for users to download and install applications on third-party platforms other than Google App Store in the future.

* Two well-known Android application download platforms

Although. aab Modular characteristics, which greatly improves the convenience of developers’ update and maintenance, and saves users’ time and storage space when installing applications.

Because of the existence of. aab, the installed applications may be different with different devices and environments.The application is also "incomplete".

Moreover, through the official documents, we found that using app bundle, developers canYou must join the Google Play application signing program..

Signing is equivalent to putting on a unique electronic label.Therefore, if the application is extracted and shared in an abnormal way, it may lead to the change of the signature and ultimately affect the operation of the application.

Unless, the developer provides it on a third-party platform.Complete application installation package.

You can only download, apply "incomplete" and share restrictions through the designated app store.

These restrictions have affected Android users.

Face challenges

If the. aab application format is implemented, for Android users, it only increases the difficulty for third parties to download applications.

Then for HarmonyOS OS,This may be a huge challenge.

As mentioned at the beginning, most of HarmonyOS’s OS software is mainly based on Android applications. Therefore, if Google fully uses. aab, it will definitely create unfavorable conditions for HarmonyOS.

At present, Huawei cannot use Google, so it has established its own application ecosystem. AppGallery .

However, in the future, the application of. aab can’t be put on the shelves, and users can’t download and install it. These problems need to be solved.

Some people may say that it is only overseas Android, and it should not affect China.

But the fruit is to say, don’t be too optimistic.

For example, the current customization system of Android 11,Can no longer access the data directory, which is mandatory by Google.

Windows 11 will also face this problem.The front foot just supported the installation of Android apk, and as a result, Google is playing this trick now, which makes users have to think that this is a monopoly.

Fruit always hopes that HarmonyOS can launch Native as soon as possible. . app and. hap Applications, really make their own ecology, break the monopoly.

Google, I advise you, you can’t achieve mutual benefit, at least you can win!

In addition, chief producer Shen Xiaoying, production designer Zhai Tao, styling director Dora Ng, voice directors Du Duzhi and Shu-Yao Wu, original music director Jianqi Chen, editing directors Ching-Song Liao and Jinglei Kong are all outstanding in their respective industries.


With such a group of professionals and three actors, Jing Bo Ran, Zhou Dongyu and Tian Zhuangzhuang, the quality of Later Us is guaranteed. Five days before the screening, the first-day pre-sale box office of "Later Us" has exceeded 50 million yuan, accounting for nearly 50% of the films, and continues to lead the May 1st file.


Peggy Chiao, a well-known filmmaker and former chairman of the Golden Horse Award for Taiwanese films, Wang Zhonglei, the boss of Huayi Brothers, directors Chen Kexin, Huang Jianxin, Gu Changwei, Zhang Jiajia, Li Yu, Chen Sicheng, Han Yan, Dapeng, animal Xiaoxing Yi, Mai, actors Huang Xiaoming, Wang Baoqiang, Song Jia, Liang Jing, Li Xia, Li Jing and Du Jiang all watched. To everyone’s surprise, The Later Us is not only touching the love story of Lin Jianqing (Jing Bo Ran) and Fang Xiaoxiao (Zhou Dongyu), but also the love of Lin Fu (Tian Zhuangzhuang) for his children. When the movie ended and the lights came on, the auditorium was really crying, and the audience was moved by the movie.


 Wang Baoqiang spoke first and said "special" eight times in a row.


As soon as director Rene Liu came to power, Wang Baoqiang, who was sitting in the audience, was so excited that he shouted "especially beautiful"; When producer Zhang Yibai took the stage with three leading actors, Wang Baoqiang was the first to speak: "First of all, congratulations on my sister’s film, which was so beautiful. I can also feel the investment in your shooting, which is particularly vivid, very good, very good and very real, and the director’s technique is very mature … … Especially beautiful, I cried and laughed several times, and I was moved by laughter. It’s really beautiful. I believe it will explode after the release. At first glance, it is an explosion, and it must be a big sale, surpassing all movie box offices. "


In his short speech, he said "special" eight times, and Wang Baoqiang was the most intimate "audience" of Later Us. Wang Baoqiang and Rene Liu became attached to each other because of the film directed by Xiaogang Feng, and since then they have always been regarded as siblings. Wang Baoqiang also said that he had already made two movies and invited relatives and friends to watch them. Moreover, "I will always make up for it later, because many friends around me really want to see it."


How good is Later Us? Chen Kexin boasted about Rene Liu.


It was not only the movie that moved people to tears, but also the words of director Chen Kexin that made Rene Liu cry. He laughed and said that he envied Rene Liu, because in the era when he first started as a director: "The romantic film (the hero and heroine) must be together in the end, and now the romantic film must not be together. I feel very envious and very beautiful." He turned his head and praised Zhou Dongyu and Jing Bo Ran: "Zhou Dongyu, as always, is good every time; But this time I think it’s finally time to wait for Jing Bo Ran. Small fresh meat must grow up, and finally wait until you grow up, congratulations. "


These words drew Rene Liu to tears on the stage. She said modestly that she still doesn’t know what making a movie is, "but I just think … … I really hope to do something sincerely, that’s all. Leave the rest to others. Thank you very much. I am very excited to be here today. There are too many people who have followed me all the way. Thank you. "


It’s hard for a female audience to watch Later Us without crying.


"Later Us" is simply a "tear artifact" for female audiences. At yesterday’s premiere, more than 90% of female audiences cried. Director Li Yu said that her brain swelled because the film was "sincere, affectionate and devoted to telling such a sorry story, although sad, but not desperate". She even said that when watching the film, she recalled those days when she first started drifting north.


Song Jia, Nicole, Li Xia and Li sat quietly together, while Dapeng, who was sitting in front of them, described it as "hearing a runny nose all the time" in the process of watching movies. Song Jia admits that he seldom cries when watching movies, but "I just secretly shed tears several times … … I haven’t seen such a real love movie in the movie for a long time "; Liang Jing said that she couldn’t help it; Li Xia described his heart as "deeply touched, because it is particularly precious to miss too much"; Li Jing directly described the film as "perfect".


Huang Xiaoming’s "concluding remarks" life is often missed.


But in fact, crying at the movies is by no means a patent for female audiences. In addition to Wang Baoqiang, Huang Jianxin also boldly admitted that he shed tears four or five times and was "moved"; Xiaoxing Yi, the animal, declared that this was his "most tears in the cinema".


Gu Changwei said that he was not such a tearful person, but "he was very, very moved later"; Han Yan admitted that he "had been controlling his emotions just now", and he also declared that he would "watch it again quietly" after the film was released. Dapeng quickly answered the phone and asked Han Yan to make an appointment with him.


What is the point that everyone is moved by? Huang Xiaoming summed it up particularly well — — "In fact, life is really so perfect? Life is often missed, lost, and back and forth, which constitutes a unique life. Why care about the result, as long as you have worked hard and loved. "


Starring in acting, Chen Sicheng envied Jing Bo Ran and Zhou Dongyu.


In addition to the film itself, the performances of the three leading actors also conquered all the audience. Huang Jianxin laughed that he was made to cry by Zhou Dongyu three times; Zhang Jiajia contributed a golden sentence, "I like this movie every second", while Jing Bo Ran and Zhou Dongyu are the "best and most glorious CP" in movies related to youth and love in recent years. Li Yu, Huang Xiaoming, Song Jia, Liang Jing, Li Xia, Li Jing and Du Jiang all praised the performances of the three leading actors.


Chen Sicheng, the director who is also an actor, also said with envy: "I especially envy Zhou Dongyu and Jing Bo Ran for getting such a good role." He also praised the two leading actors and said, "Zhou Dongyu just won an award, so why should he win another award?"? Xiaojing, I hope you also get an award. " As for Rene Liu’s first directorial work, he also spoke highly of it as "very mature, with a unique female director’s perspective and nuanced".


RAV4 will release the 2022 style upgrade, taking you to bid farewell to boredom

  SUV models can be said to be one of the most popular models in China, with spacious interior space, wide driving vision, and flexible storage space, which can meet the various needs of family travel. However, with the increasingly fierce competition in the SUV market, more and more car brands are targeting Chinese users’ love for space and pursuit of rich configuration, and the research and development direction of SUV models has become more and more single, so that the huge SUV model market is highly homogeneous and lacks innovation. And the mindless stacking of space and configuration has also caused most domestic models to deviate from the original intention of SUV versatility.

RAV4 will release the 2022 style upgrade, taking you to bid farewell to boredom

  When it comes to the original intention of SUV models, one has to mention the founder of SUV models that are popular around the world – Toyota RAV4. 30 years ago, SUVs were still the representative of hardcore off-road vehicles, focusing more on the passing of unpaved roads in the suburbs. In 1994, when the first generation of RAV4 models met with the majority of users, the concept of off-road and urban models opened people’s eyes. Good urban road handling performance, rich configuration to meet daily transportation comfort, and good off-road capabilities almost redefined the connotation of SUV models, which is what we call urban SUVs.

RAV4 will release the 2022 style upgrade, taking you to bid farewell to boredom

  As the pioneer of urban SUVs, the first generation of RAV4 has set off a boom in the global SUV market since its launch, and has always led the development trend in this field in the nearly 30-year model history. In 2018-2021, RAV4 ushered in the highlight moment of the world’s largest SUV cumulative sales. In 2018, it also won the most fuel-efficient SUV in "CONSUMER REPORT", the top ten interiors of Ward in 2019, the 2019-2020 CAR OF THE YEAR JAPAN Model of the Year Award, and the highest rating in E-NCAP and IIHS tests. Today, the RAV4 has further advanced the charm of the 2022 model, through three major upgrades: "Wild Upgrade", "Color Upgrade", and "Configuration Upgrade", inheriting the off-road model concept of taking into account the city, and further bringing SUV users in large cities, which is different from other models and surpasses the previous colorful travel experience.

  The kit has more wild charm next to the body

  Fans who follow the RAV4 Rongfang must be deeply impressed by the arrival of the fifth-generation RAV4 Rongfang in 2019, that is, the new RAV4 Rongfang. Its platform architecture has been upgraded to the same TNGA-K platform as flagship models such as the Asian Dragon and Lexus ES. Under such a reborn innovation, the strength of the model has not only leapt in an all-round way, but also the body design has more sharp lines, outlining a strong hardcore off-road style, adding a bit of wild charm to the domestic SUV market, which has been widely praised by users. Today, the RAV4 Rongfang 2022 model has leapfrogged the excellence of the new RAV4, first of all, to cater to users’ preferences for hardcore style, and further highlights the wild charm of its off-road attributes in appearance and interior.

RAV4 will release the 2022 style upgrade, taking you to bid farewell to boredom

  The RAV4 Rongfang 2022 model adds an off-road appearance kit for the 2.0L four-wheel drive version, including a more three-dimensional front/rear bumper guard, increased width and non-metallic wheel eyebrows with square texture design in its central part, as well as a more textured new dark gray wheel hub paint and a cool black exterior mirror cover.

  The redesigned front and rear bumper guards change the original inward concave shape to a square three-dimensional shape that protrudes outward, which has great visual impact. And the sharper lines and corners make the RAV4 Rongfang 2022 model further strengthen the hardcore atmosphere on the original basis. In order to meet users’ demands for a hardcore off-road feel, the RAV4 Rongfang 2022 non-metallic wheel eyebrows have increased the width on the basis of the original design, making it more visually robust and powerful. At the same time, a square texture design is added to the middle part of the wheel eyebrows, which enhances the roughness of the model and also has exquisite design details, which is enough to highlight the user’s ultimate taste.

  In addition, the new car also adds non-metallic door trim, which not only enhances the sense of stiffness, but also protects the body from the impact of sand and gravel branches in harsh road environments. At the same time, the RAV4 Rongfang 2022 has launched a new dark gray wheel hub paint, which is more delicate than the previous smoked black paint. With the addition of the new cool black exterior rearview mirror, it can create a more advanced visual sense, atmospheric dynamic, and better reflect the user’s exquisite taste.

RAV4 will release the 2022 style upgrade, taking you to bid farewell to boredom

  You know, RAV4 Rongfang was awarded Ward’s Top Ten Interiors in 2019, not only because of its better ride experience, but also because of its interior atmosphere, which is more wild and charming under the off-road style atmosphere. Now, RAV4 Rongfang 2022 has been upgraded again on the basis of the top ten interiors. The newly added off-road style high-end seat adopts a visually more off-road atmosphere and a more textured high-end fur material in the contact with the human body, and is embellished with diamond-shaped suture texture to make the off-road atmosphere of the interior more intense. At the same time, in terms of details, the new car interior dashboard, armrest box, and door guard stitches are all made of more wild and personalized colors, highlighting the interior texture while allowing you to feel the off-road atmosphere the moment you open the door.

  Configuration improvement More human care

  Although under the concept of off-road and urban models, the wild charm and off-road performance of RAV4 Rongfang are huge advantages that far exceed the competitors at the same level, the technological configuration required for daily transportation in the city has never been ignored. This time, FAW Toyota started with user requests, and on the basis of the old model, the practical configuration of the model has also been upgraded.

RAV4 will release the 2022 style upgrade, taking you to bid farewell to boredom

  For example, on the basis of the original electric folding exterior rearview mirror of the old model, the new car has been upgraded to an automatic folding exterior rearview mirror, and a parking radar system has been added to some models. The improved configuration can provide more convenience for daily travel. In addition, the new car also adds a kick sensing function on the basis of the original electric tailgate configuration, which highlights the sense of technology and allows more users to experience the charm of technological configuration.

  All-round genes are more fun to drive

  The all-round strength of RAV4 Rongfang is not only derived from the inheritance of the concept of urban SUV models in the past 30 years, but also from the technical strength shown after the iteration of generation models. Whether it is the combination of power and fuel consumption of the TNGA 2.0L DYNAMIC FORCE engine, the expedition endurance of the TNGA 2.5L dual-engine hybrid system (THS ⅱ) with a tank of fuel for 1,000 kilometers, or the three rare four-wheel drive systems of the same class, the all-round strength of the city SUV is vividly displayed.

  Of course, good driving control texture not only comes from the surging and efficient power, but also the control experience brought by the vehicle architecture and suspension system is particularly important. Under the blessing of the TNGA-K platform, RAV4 Rongfang has a GOA body, of which high steel, lightweight body, using hot stamped rigid, the highest 1.18 quadrillion Pa high-strength steel plate and aluminum application, while achieving high steel and lightweight, laying a good foundation for its superior control experience, and also to a certain extent to improve the passive safety of the vehicle.

Suing the Trademark Office for dispute, who is the legal representative of Wahaha?

  A few days ago, the Beijing No. 1 Intermediate People’s Court confirmed to the media that it has received a complaint from Hangzhou Wahaha Food Co., Ltd. against the Trademark Office of the State Administration for Industry and Commerce. The complaint contains the name of Fan Yimou, the vice chairperson of Hangzhou Wahaha Food Co., Ltd. It is understood that the Beijing No. 1 Intermediate People’s Court has accepted the case.


  The prosecution immediately attracted the attention of all parties and also attracted various controversies.


  "We did not file a lawsuit against the Trademark Office of the State Administration for Industry and Commerce with the Beijing No. 1 Intermediate People’s Court, but asked the court who used our name to sue, and asked to withdraw the lawsuit, reserving the right to pursue the impostor’s legal responsibility," said Shan Qining, a Wahaha spokesperson, in a statement sent to this newspaper. The statement ended with the official seal of Hangzhou Wahaha Food Co., Ltd.


  Who has the authority to represent the joint venture company?


  Obviously, from the above situation, Fan Yimou represented the identity of the major shareholder of the Wahaha joint venture company and played the role of the legal representative of the joint venture company. The Chinese side of the Wahaha joint venture company was obviously unwilling to recognize Fan Yimou’s legal representative identity. For a time, the battle for control of the Wahaha joint venture started again.


  A few days ago, some media reports said that Danone believes that it has the right to sue the Trademark Office on behalf of the Wahaha joint venture. However, Wahaha is unwilling to admit the facts and asks to withdraw the lawsuit. So does Fan Yimou really have the right to sue the State Trademark Office on behalf of the joint venture?


  "We have no comment." Danone said the reports were false, as did Shan Qining, Wahaha spokesperson.


  "Whether the vice-chairperson can exercise legal rights on behalf of the company can be debated." Yan Yiming, a well-known rights lawyer in Shanghai, said that there are three situations in which legal rights are generally exercised on behalf of a company. The first situation is the chairperson, who is the legal representative; the second is the official seal; and the third is that if the vice-chairperson wants to exercise legal rights on behalf of the company, it must be approved by the board of directors. In addition, the general manager of the company represents the company and exercises management power internally.


  In response, Zhang Malin, a lawyer at Jiangsu Zhibang Law Firm, said that if Fan Yimou is an interested party, it should be possible to sue the State Trademark Office in the name of an individual, but if he is suing in the name of a company, it depends on whether he can have evidence to exercise his rights on behalf of the company. He said that the Beijing No. 1 Intermediate Court has now accepted the lawsuit, indicating that the court believes that the evidence is sufficient, so it is inferred that the complaint should have the official seal of Hangzhou Wahaha Food Co., Ltd.


  However, it is strange that the statement sent by Wahaha spokesperson Shan Qining to this newspaper ended with the official seal of Hangzhou Wahaha Food Co., Ltd., which shows that the official seal should be on Wahaha’s side. So how did Fan Yimou put the official seal on the complaint, but Wahaha’s side was "unaware"?


  Zong Qinghou’s resignation was not completed?


  On June 7 this year, Zong Qinghou, the chairperson of the Wahaha joint venture, wrote his resignation letter to the headquarters of Danone in France because he was "intolerable". Danone said it accepted Zong Qinghou’s resignation and appointed Fan Yimou as the interim chairperson of the joint venture.


  In late June, Fan Yimou convened the board of directors of Wahaha’s seven joint ventures, demanding that he be elected as the chairperson of the company and that Wahaha hand over its official seal and business license, but the meeting failed to reach any agreement and ended in a farce.


  According to the joint venture articles of association between Danone and Wahaha, the two sides agreed that the chairperson should be elected by the board of directors. Since Wahaha’s Chinese side strongly resisted Fan Yimou and claimed that according to the articles of association, the chairperson of the joint venture company should be appointed by the Chinese side. From this point of view, Fan Yimou should not have been successfully elected as the new chairperson of the company.


  "Zong Qinghou’s resignation application should be effective, but the final resignation process should not be completed." Yan Yiming said that resignation does not mean that the legal representative status is automatically lost. It must be approved by the board of directors and the registration of legal person change must be completed at the local industry and commerce bureau. The entire resignation procedure is considered to be completed.


  Yan Yiming also said that from the current media reports, it is difficult to say who wins and who loses. It should be said that both sides have the opportunity to win the lawsuit, but it does not rule out the possibility of automatic settlement between the two sides when the lawsuit is halfway through.


  Wu Dong, deputy director of the company law committee of the Shanghai Bar Association, said that one of the most important roots of the Danone-Wahaha dispute was related to China’s original approval system for Sino-foreign joint ventures, and the "administrative inaction" of the State Trademark Office was one of the reasons for the contradiction. This is also the reason why Danone began to sue the State Trademark Office.


  Wu Dong said that Danone and Wahaha knew that the trademark transfer agreement could not be passed, so they signed a trademark license contract. It is ridiculous that now Danone and Wahaha both claim to solve the problem through legal means. Why did they circumvent Chinese law in the first place? If the Chinese law was strictly followed at that time, the two sides would not have such disputes.


  According to media reports, the State Trademark Office will not comment until the final result comes out. (Fu Guangyun)

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.
