Huawei recently launched the world’s first largest and thinnest commercial three-fold screen mobile phone, which not only triggered a pre-sale boom, but also caused widespread discussion at home and abroad. The advent of this product highlights the rapid development of domestic mobile phones in technological innovation. For a long time, domestic mobile phones have followed Apple, Samsung and other brands and constantly pursued innovation. Although the concept of three-fold screen mobile phone has long been put forward, the leap from concept to mass production involves the comprehensive upgrade of production objectives, design concepts, technical maturity and market positioning. Compared with double folding, triple folding is not only an innovation in appearance, but also a major breakthrough in hinge and screen technology, which effectively responds to consumers’ demands for equipment reliability, thinness and screen quality, and fully demonstrates the technical strength of domestic mobile phones.

This further consolidated the leading position of domestic mobile phones in the high-end market. With the smartphone market entering a saturated state, consumers’ replacement cycle is prolonged, industry growth slows down and consumption upgrades go hand in hand. Faced with the high cost of R&D and innovation, domestic mobile phone brands are advancing to the high-end market one after another. Folding screen mobile phone is the highlight of high-end market. Huawei’s leading three-fold screen mobile phone marks the change from following to leading. Especially in the case of releasing new products at the same time as Apple, this move is regarded by overseas media as a direct manifestation of brand influence and the scientific and technological strength of China and the United States.

Although it is uncertain whether the three-fold screen mobile phone will become the mainstream form of the future folding screen mobile phone, it does bring new ideas to the market. At present, the folding screen mobile phone has shown many forms, such as horizontal internal and external folding and vertical folding, and the three-fold mainly meets the specific needs of business people and technology enthusiasts. The price of nearly 20,000 yuan announced by Huawei triggered some netizens’ feedback about the high price. Due to the high cost of technology and configuration, the three-fold screen mobile phone is currently positioned in a niche market, and it is difficult to achieve large-scale popularization and substantial price reduction in the short term. In addition, improving thinness and durability is essential to attract more users.

It should not be ignored that the three-fold screen mobile phone is an important step to promote the evolution of smart phones. It can be seen from netizens who dubbed it "LCD TV that can be put into pocket" that smart phones are evolving towards a larger screen. Since 2018, global smartphone sales have declined, but the folding screen mobile phone has maintained steady growth. Its unique form successfully combines portability and large screen, providing users with a brand-new experience. Therefore, regardless of the form, the pursuit of larger display area is the inevitable trend of the development of smart phones.

The emergence of three-fold screen mobile phones has also brought new vitality to the smart phone market. This year, with the centralized release of new technology mobile phones such as artificial intelligence, folding screen and 5G, the market demand has been released, which will help the market recover and achieve growth. The mass production of three-fold screen mobile phones not only opens up new growth points in the market, but also promotes the improvement of the industrial chain, bringing more development opportunities for upstream and downstream enterprises.

Li Keqiang presided over the the State Council executive meeting.
Deploy and improve the accelerated depreciation policy of fixed assets to promote technological transformation and entrepreneurial innovation of enterprises
Decided to further open the domestic express delivery market and promote fair and orderly competition between domestic and foreign investors.

　

　

　　　　　　　On September 24th, Li Keqiang, Premier of the State Council of the People’s Republic of China presided over the the State Council executive meeting, deployed and improved the accelerated depreciation policy of fixed assets, promoted technological transformation of enterprises, supported the entrepreneurial innovation of small and medium-sized enterprises, and decided to further open the domestic express delivery market and promote fair and orderly competition between domestic and foreign investors.

　　　　 The meeting pointed out that in order to conform to the trend of the new technological revolution and push China’s economy to the middle and high-end level, we must make greater efforts to promote technological transformation of enterprises. It is of great significance for traditional industries to "break through the cocoon", enhance the stamina and vitality of economic development, and achieve quality upgrading, efficiency upgrading and sustained and stable growth by improving the current accelerated depreciation policy of fixed assets, reducing the tax burden, speeding up enterprise equipment renewal, scientific research and innovation, expanding manufacturing investment and promoting mass entrepreneurship. The meeting confirmed that, first, the newly purchased instruments and equipment for R&D in all industries after January 1, 2014, with a unit value of no more than 1 million yuan, are allowed to be included in the current cost at one time and deducted before tax; If it exceeds 1 million yuan, the depreciation period can be shortened by 60%, or the depreciation can be accelerated by methods such as double declining balance. Second, fixed assets with a unit value of no more than 5,000 yuan held by enterprises in all industries are allowed to be included in the current cost at one time and deducted before tax. Third, for the fixed assets newly purchased by enterprises in biopharmaceutical manufacturing, special equipment manufacturing, railway, shipbuilding, aerospace and other transportation equipment manufacturing, computer, communication and other electronic equipment manufacturing, instrumentation manufacturing, information transmission, software and information technology service industries after January 1, 2014, it is allowed to shorten the depreciation period by 60% of the specified period, or adopt accelerated depreciation methods such as double declining balance to promote the expansion of imports of high-tech products. According to the implementation, timely expand the scope of the industry to which the policy applies.The meeting called for speeding up the implementation of the above policies, striving to arm "Made in China" with advanced technology and equipment, and launching products with higher added value and stronger market competitiveness.

　　　　 The meeting held that expanding all-round active opening-up and creating a business environment in which domestic and foreign-funded enterprises are treated equally and compete fairly is a major policy orientation that China has long adhered to. At present, China’s international express delivery business has been basically opened to foreign investment, and domestic express delivery business in major cities has also been opened to some foreign-funded enterprises in batches. According to China’s commitment when it joined the World Trade Organization, further opening up the domestic market and allowing domestic and foreign express delivery enterprises to compete on the same stage will help to force domestic enterprises to improve their management and service level, so that consumers have more choices. At the same time, promoting the express delivery industry to become the "dark horse" of the development of modern service industry can also promote the logistics industry to a higher level, further invigorate circulation, stimulate domestic demand, increase social employment, and actively contribute to stabilizing growth, restructuring and benefiting people’s livelihood. The meeting decided to fully open the domestic parcel delivery market, and issue business licenses to foreign-funded express delivery enterprises that meet the licensing conditions according to the approved business scope and business area. The meeting stressed that it is necessary to adhere to the combination of release and management to ensure the orderly and healthy development of the express delivery industry. First, improve the business licensing procedures and strengthen the qualification review. Simplify procedures and improve efficiency. The second is to promote the joint development of express delivery, e-commerce and manufacturing, smoothly connect with the comprehensive transportation system, and support the solution of problems such as the difficulty of urban express delivery vehicles. Ensure the safety of delivery. The third is to encourage the merger and reorganization of express delivery enterprises, and improve and implement the systems of reorganization filing and review of foreign mergers and acquisitions. Strengthen the management of agents and franchisees, and seriously investigate and deal with illegal business operations, out-of-scope business operations, illegal agency and other acts. Make express delivery, a sunrise industry, more prosperous and create conditions for stimulating residents’ consumption.Convenient for the vast number of businesses and hundreds of millions of people.

　　　　The meeting also studied other matters.

　 　 1905 movie network news Since the launch news was exposed, it has attracted much attention. How to shoot a sequel to a classic film, whether Liu Zhenwei, who has been short of masterpieces in recent years, can grasp the IP in his hand, and whether the newly added Han Geng Jason Wu can continue the myth have all become questions in the hearts of the media and fans.

　 　　On June 13th, "A Chinese Odyssey 3" held a press conference in Shanghai, announcing that it was scheduled for August 19th. Han Geng revealed that he had rejected the role three times, and Jason Wu even revealed that he and Han Geng had a kiss in the film, which caused his wife Iola to complain on the spot that "all the actors who cooperated with him can become CP, can I still stop!"

Han Geng once refused to appear for three times, exposing Wu Jing to kiss and eat garlic first.

　 　　His first two films are classics of Chinese movies, and they are also important works to establish the status of Stephen Chow film industry. Han Geng admits: "There is a mountain like Xingye in front, so I pushed it three times. After that, the director has been talking to me. After the entanglement, I still don’t want to lose this opportunity."

　 　　As the latest in the series, the film has added some new points of view compared with the original. Jason Wu said that it was "the first time that he had such a shameless intimate lover and intimate scenes". This close lover is Han Geng. When talking about kissing, Han Geng said with a smile, "He is very bad. He took a bite of garlic, and I really couldn’t talk."

　 　　Speaking of this, Iola, a family member of Jason Wu, first said, "Why do I feel like the heroine of this play?" Then he complained, "All the actors he worked with can become CP, first Zhang zhen, and now Han Geng. Can I stop?"

Jason Wu first sang the golden song "only you" and wanted to play mother and son with Iola.

　 　　In the movie "A Chinese Odyssey 3", Jason Wu, who plays the Tang Priest, could not help singing "only you". Because Luo Jiaying’s version was too classic, Jason Wu was under a lot of pressure at first. Later, with the help of the original author Lu Guanting, he "sang a new feeling with the voice of martial arts" and "sang Sun Nan, and this time I sang Lu Guanting."

　 　　As a more successful kung fu star, Jason Wu rarely plays a role of pure literary drama. In order to play the sermon of Tang Priest, Jason Wu admitted to learning from his wife, Iola, and became more eloquent. Iola also said that after marrying Jason Wu, her action scenes became more and more. In the film, she played the role of Princess Iron Fan with many action scenes.

　 　　However, the two missed the opportunity to play the husband and wife file. In this regard, Jason Wu does not feel sorry. In his view, it is best if the two can play mother and son: "The audience is always watching us show love, which is boring. If Jason Wu is called Iola’ Mom’, the effect will definitely be good."

　　China Meteorological News correspondent Dong Yongchun Wang Ting

　　Recently, the "Guangdong Province Air Pollution Prevention and Control Strengthening Measures and Division of Labor Plan" (hereinafter referred to as the "Strengthening Plan") issued by the General Office of the Guangdong Provincial Government proposed that "all localities should fully consider the long-term impact of climate change when planning, designing and approving urban infrastructure construction and renovation projects, and prohibit the construction of new high-rise buildings on urban ventilation corridors." This is also the first time that urban ventilation corridors have been written into Guangdong’s environmental protection policy.

　　In recent years, Beijing, Hangzhou, Wuhan, Xi ‘an, Chengdu, Guangzhou, Huizhou and other places have brought ventilation corridors into the vision of planning and decision-making. Among them, Guangzhou was listed as the second batch of national urban design pilot cities by the Ministry of Housing and Urban-Rural Development this year. The overall urban design of Guangzhou, which is being compiled, also requires further establishment of a more detailed ventilation corridor scheme.

　　Why do ventilation corridors attract the attention of more and more cities? How should it be planned and constructed, and will the areas along the line face large-scale demolition and construction? With these questions, the author interviewed Wang Chunlin, deputy director of Guangzhou Climate Center and a senior engineer at the research level.

　　Why build it?

　　-It can reduce air pollution and alleviate the urban heat island effect.

　　As early as two or three years ago, urban ventilation corridor has been included in the research field of Guangdong meteorological department. According to Wang Chunlin, the leader of the research team, the urban ventilation corridor is a passage for introducing fresh cold and humid air to the urban area with the purpose of improving the air mobility of the city, alleviating the heat island effect and improving human comfort. Generally speaking, the "ventilation corridor" is just like the "urban air duct", similar to a long and narrow ventilation duct, which can make the urban wind "pass through the hall".

　　"Our ventilation corridor planning is mainly based on the Technical Guide for Urban Ventilation Corridor Planning issued by China Meteorological Bureau at the end of 2015." Wang Chunlin said that many developed countries and regions have already started in this respect. Munich, Germany began the practice of introducing ventilation corridors into urban planning in the 1970s. Tokyo, Japan has long established a five-level ventilation corridor system combining mountains, valleys, sea, land and parks.

　　In 2006, the Hong Kong Planning Standards and Guidelines set out the definition and function of urban ventilation corridors (air ducts) in urban planning for the first time: ventilation corridors should be connected by large open areas, such as main roads, connected open spaces, beautification zones, non-construction sites, construction line backward zones and low-rise buildings. Ventilation corridors should extend in the direction of prevailing winds, and if feasible, other natural gas flows, including ocean, land and valley winds, should be maintained or guided to blow to urban areas.

　　Wang Chunlin believes that ventilation corridors have many advantages. "First, they can effectively alleviate the various impacts caused by urban heat island effect; second, they can help urban air flow and pollution diffusion; and third, they can greatly improve human comfort in terms of temperature and urban air quality."

　　Take Beijing as an example. In 2012, when the heat island area of six districts in the city center was serious, it accounted for 77% of the total area. In recent years, the trend of urban wind speed decreasing is also obvious. In this regard, He Yong, deputy director of the Planning Research Office of Beijing Urban Planning and Design Institute, said that the ventilation corridor is not to "create wind", but to make the cold air in the suburbs flow to the urban area more smoothly and "change" the hot air in the urban area, thus effectively reducing the urban temperature.

　　How to lay out?

　　-big data analysis of wind environment and planning according to local conditions

　　For cities with different geographical conditions, how to set the direction and route of ventilation corridors?

　　At present, the team led by Wang Chunlin is studying and experimenting to analyze the urban wind environment through huge data analysis and computer simulation experiments, which is an important basis for planning urban ventilation corridors. He introduced that at present, the analysis of urban wind environment mainly adopts the Mesoscale Meteorological Model (WRF), which is a new generation of mesoscale forecasting model and assimilation system jointly developed by American meteorological circles. The land surface process model in WRF is coupled with the Urban Canopy Model (UCM). By adjusting the regional urban parameters such as urban reflectivity and roughness, it has a good simulation ability for urban heat storage effect, flow field and precipitation distribution.

　　"To analyze the wind environment, we must first master a large number of urban underlying surface data and wind observation data." Regarding the design principle of urban ventilation corridor, Wang Chunlin said that the data of urban underlying surface include the distribution, height and geometric structure of buildings, as well as the distribution of terrain height, green space and water bodies. Wind observation data include wind force, wind direction and other elements. Taking Guangzhou as an example, the available wind observation data include the data of five national weather stations in Guangzhou in recent 30 years and about 300 regional weather stations in recent 10 years.

　　"Secondly, the fine-grid meteorological dynamic model is an important tool to carry out urban wind environment analysis and ventilation corridor planning effect evaluation." Wang Chunlin said that Guangzhou Meteorological Department has a large number of historical data and 400 trillion supercomputers per second, which can make statistical analysis on the output results of massive models and quantitatively compare the ecological benefits of different ventilation corridor planning schemes.

　　In the planning process, adapting to local conditions is an important principle. On the one hand, the existing ecological cold sources such as green space, parks, forests, rivers and lakes should be included in the wind gallery, which can better protect the ecological cold sources and make them play the role of purifying the air and reducing the urban heat island effect. On the other hand, the existing urban pattern should be fully respected, and the planning of wind corridors should try to avoid the existing large-scale buildings and avoid a large number of demolition.

　　"Just like urban roads have roads and paths, ventilation corridors are divided into first-class corridors and second-class corridors." Wang Chunlin said that the first-class corridor is equivalent to the main road and is the main ventilation corridor; The second-level corridor should be built along the area with great ventilation potential, and try to make up for the "broken" corridor area that the first-level corridor cannot guarantee.

　　At present, there are five or more main ventilation corridors in Beijing, Hangzhou, Chengdu and other cities, and there may be more secondary corridors.

　　On the principle of division of labor and design, the design of the first-class ventilation corridor should be as parallel or nearly parallel as possible to the dominant wind direction of the city, and make full use of the ecological cold sources such as green space, mountains and rivers with large area and good ecological environment. The setting of the secondary corridor should play the role of assisting and extending the ventilation efficiency of the primary ventilation corridor, and communicating and connecting the local ecological cold source and the areas with poor wind environment. With the help of urban trunk roads, squares, water systems and other open spaces, the final "wind corridor network" should be formed. The setting of the width, length, direction and land use control of the wind corridor should be combined with the refined wind and heat distribution characteristics and realistic construction conditions in the urban area.

　　What are the design principles?

　　-determine the direction of the wind corridor according to the prevailing wind direction in the city.

　　During the implementation of urban ventilation corridor planning, the stipulation that "no new high-rise buildings are built on urban ventilation corridors" mentioned in Guangdong’s "Strengthening Plan" has attracted much attention.

　　Does this mean that the existing buildings will be demolished and built? Wang Chunlin believes that the existing high-rise buildings should not be demolished artificially, but should be demolished by natural elimination after reaching the service life, so as not to waste resources.

　　It is forbidden to build new high-rise buildings on urban ventilation corridors for two reasons: first, high-rise buildings will increase the roughness of urban underlying surface and reduce the air circulation efficiency of air corridors, which is the bottleneck area of air flow. Second, the high-rise building on the wind gallery has a large windward wind speed, which has many disadvantages: a large area of quiet wind zone is formed at the back of the high-rise building, which will be extremely stuffy in summer and affect comfort; If there are pollutants in the back of it, it will cause air pollution in the near-surface layer and affect human health.

　　"Even if some buildings are very tall, whether they will have a great impact on the wind gallery requires specific analysis." Wang Chunlin said. It is assumed that the new central axis of Guangzhou, which extends from Tianhe North Road to flower city square, is also set as a ventilation corridor, and the towering small waist (also known as Guang Zhouta) is just in the middle below the central axis. However, due to the slender structure of the small waist building and the hollow design, it will not cause great obstruction to the wind corridor.

　　The prevailing wind direction in the city is the decisive factor affecting the direction of the wind corridor. Wang Chunlin said that taking many cities in the Pearl River Delta, such as Guangzhou, for example, the southeast wind prevails in summer and the northerly wind prevails in winter, and the north-south wind corridor is conducive to utilizing the ecological cold source in Conghua and other places in the north and the ocean cold source in the south.

　　At present, the Master Urban Design of Guangzhou, which is being compiled in Guangzhou, also clearly requires that the main corridors where the dominant wind direction enters the city should be determined, and the strategy of "making wind, gathering wind and ventilating" should be put forward to establish the urban wind corridors, water corridors, green corridors and visual corridors in Guangzhou.

　　How to implement the plan?

　　-there is still a lack of unified standards, and all localities are exploring.

　　When the Eight Immortals crossed the sea, they all showed their magical powers. In fact, at present, there is no uniform standard for urban ventilation corridors in mainland China, and all localities are still groping for it in practice.

　　Wang Chunlin revealed that Guangzhou was listed as the second batch of urban design pilot cities this year. In this year’s overall urban design of Guangzhou, the planning and design department initially planned and designed the ventilation corridor system of Guangzhou based on the numerical simulation of Guangzhou’s wind environment.

　　However, many cities that are more advanced in the research and planning of ventilation corridors also face some confusion in practice. For example, in many ventilation corridors planned and built in Beijing, there are still many high-rise and dense building communities, which will become the bottleneck area of air flow.

　　Wang Chunlin believes that the planning and improvement of urban ventilation corridors need to be fully discussed and communicated with urban planning departments to jointly promote the planning and implementation of ventilation corridors.

　　In fact, in addition to directly planning urban ventilation corridors, many places have also taken some measures to improve urban microclimate. For example, Shenzhen will treat the first floor of real estate as an overhead floor into the overall urban planning, and rationally arrange the layout of urban buildings; Thirty pilot cities, including Xiamen, Chongqing and Nanning, have accelerated the construction of "sponge cities".

　　Wang Chunlin revealed that the changes of local ventilation volume and heat island intensity before and after ventilation corridor planning can be accomplished by means of numerical simulation, field observation or wind tunnel test. Among them, the fine simulation of local wind environment can be carried out by computational fluid dynamics (CFD). He introduced that CFD is a combination of modern fluid mechanics, numerical mathematics and computer science. Using electronic computer as a tool, it applies various discrete mathematical methods to conduct numerical experiments, computer simulations and analytical studies on various problems of fluid mechanics in order to solve various practical problems. However, due to the huge demand for computing resources, CFD technology is usually applied to the simulation and analysis of wind field in residential areas, and a wider range of applications can be tried in the planning of urban ventilation corridors in the future.

　　Link: Controversy about Ventilation Corridor

　　There is a classic line in the movie "Be there or be square": Blast the Himalayas into a 50-kilometer-wide hole, let the warm and humid air from the Indian Ocean blow into the Qinghai-Tibet Plateau through Nepal, completely change the harsh ecological environment there, take off the backward hat there, and turn the Qinghai-Tibet Plateau into a beautiful and rich land of fish and rice. This line is also used to ridicule the ventilation corridor. Indeed, a new engineering design is still in the stage of scientific demonstration, which will cause a lot of controversy.

　　One of the focuses of controversy is whether the smog can be blown away. Opponents believe that the main reason for the smog in winter is that the cold air is weak, and the warm and humid air from the south goes north, and after the stalemate, it forms static weather. If you want to disperse the smog through the ventilation corridor, you must have wind first, but there is no wind in calm weather. Supporters believe that the existing research proves that the formation of ventilation corridor network in the central city is effective in improving the microclimate and has a certain auxiliary role in promoting the diffusion of pollutants.

　　Another focus of controversy is whether successful experiences can be replicated. According to reports, there is a burning wind every year in Munich, Germany, and five urban ventilation corridors are planned and built locally to let the burning wind pass through the city and take out the dirty air in the city. The effect is very good. However, some opponents believe that the wind burning in Munich is caused by the geographical factors on the northern slope of the Alps. Unlike the climate background of many cities, it is still unknown how much the ventilation corridor can play in other cities.

　　There are still some controversies surrounding the practical difficulties in construction. Some people think that urban construction is basically taking shape, and the landing of ventilation corridors in the future depends on urban planning, which is difficult to achieve overnight. Others question whether smog and heat waves will affect the surrounding areas if they are successfully dispersed by ventilation corridors. Supporters said, first, there is no need to "make a big move" on urban construction, just make a slight adjustment; Second, the pollutants carried away by air flow will not only spread to the open areas around the city, but also spread to the sky, and it is a process of gradual dilution, which will not affect the surrounding areas.(bian Ji)

　　(Source: China Meteorological News August 21, 2017 Third Edition Editor: Tang Miao)

　　

　　Bauhinia. com (special correspondent Wang Yichuan) Beijing comprehensive report on June 22nd: At present, the new energy vehicle market is still a scene of "loud thunder and little rain". In the past two years, the state has issued a series of support policies and incentives for the development of new energy vehicles, but the overall market is worse than expected.

　　According to the data released by China Association of Automobile Manufacturers, the sales volume of new energy vehicles in China in 2015 was 330,000, far below the planned target of 500,000. Faced with the advantage of subsidizing more than 100,000 yuan for a car, why don’t consumers buy it?

　　"There are certainly factors such as slow construction of charging piles and limited travel radius of car owners, but the most fundamental thing is that consumers have a lot of concerns." An auto industry analyst pointed out that in the current auto industry structure in China, most consumers are still skeptical about domestic auto brands, not to mention new energy vehicles with low battery research and development level, which is the main crux of consumers’ lack of confidence.

　　Mr. Chen, the owner of Tengshi, who lives in Dongcheng District, Beijing, has been troubled by battery failures many times recently. As a pure electric vehicle positioned in the mid-to-high-end market, Tengshi is jointly produced by BYD and Daimler. The manufacturer BYD Daimler New Technology Company is located in Shenzhen, and it is mainly sold in Beijing, Shanghai, Guangzhou, Tianjin, Hangzhou, Shenzhen and other cities where the number of cars is limited.

　　"The car price is nearly 400,000 yuan. After deducting the state subsidy of more than 100,000 yuan, we paid 291,000 yuan for the car and bought a distinguished version of Tengshi." Mr. Chen said that it was only nine months since he bought the car, but since April this year, the car has had three battery failures, the most recent of which was in early June. At present, his car is still parked in the 4S shop, waiting for the opinions of dealers and manufacturers.

　　According to informed sources, Tengshi has been sold in Beijing for more than a year, and many cars have experienced power battery failures. "The heart of the fuel vehicle is the power system, and the heart of the new energy vehicle is the battery system." The source said that although the country spared no effort to support, manufacturers and distributors of new energy vehicles also shouted loudly, but if they did not work hard on the battery system, they would undoubtedly be blinded by the clouds and eventually abandoned by the market.

　　The "battery king" is badly hurt.

　　When it comes to BYD, many people will think of its leading position in rechargeable batteries. Especially in the context of the global promotion of green environmental protection and China’s vigorous implementation of the concept of sustainable development, BYD has continued to increase the pace of expansion.

　　In 2010, BYD "overtook" Daimler Group and joined hands with Nuggets to explore the China new energy vehicle market with unlimited potential. In September, 2014, this "perfect match" marriage came to fruition, Tengshi pure electric vehicle jointly developed by both parties went on sale, and round after round of marketing offensive also rolled in.

　　However, judging from the situation of Tengshi owner Mr. Chen, the marriage between BYD and Daimler is not as beautiful as it looks. "On September 9, 2015, we bought a Tengshi Premium Edition car at Pangda Xinhong New Energy Automobile Sales Company in Yizhuang, Beijing. At present, it only travels more than 1,700 kilometers, but there have been three serious safety problems of car battery failures in the past two months." Mr. Chen said angrily that Tengshi has repeatedly claimed that "battery power technology is our housekeeping skill", but facts speak louder than words, and Tengshi’s frequent battery failures also make its marketing offensive look pale and powerless.

　　According to Mr. Chen, on April 7, 2016, I planned to send my children to school by car, but I found that the car parked in the basement could not be started, so I called Tengshi rescue. After the maintenance personnel came to check, it was called a small battery failure, and some treatment was carried out. To his dismay, when he was ready to send the children the next morning, he couldn’t start again, so he called the rescue phone. The rescuer said that "the second rescue will be charged" and suggested that they call the 4S shop after-sales phone; After the 4S shop maintenance personnel came to check, the cause of the failure was not clear. Mr. Chen and his family immediately requested to replace the power battery, but the maintenance personnel said, "We should drive the car back to the 4S shop for testing." One day later, the 4S shop verbally informed Mr. Chen that "the small battery was replaced".

　　On the morning of June 6, Mr. Chen and his family drove to the 4S shop to film, and at the same time upgraded the system due to navigation problems. When preparing to return, I found that the car could not start again, showing "power system failure". After preliminary inspection by maintenance personnel, it was said that the fuse of the power battery was blown. Mr. Chen waited for several hours in the 4S shop without results, so he had to return home. For more than 10 days, the car has been parked in the huge Xinhong 4S shop, and Mr. Chen is still anxiously waiting for the handling opinions.

　　"No matter who knows, how important the safety of batteries is for pure electric vehicles." Mr. Chen said that three battery failures occurred in just two months, and he felt very depressed and uneasy. The serious quality problems made them afraid to use the car again, so they repeatedly requested the replacement of the car to Huge Xinhong and BYD Daimler Company.

　　For more than 10 days, Mr. Chen and his family have had difficult communication with dealers and manufacturers. "We called the service number many times to clearly put forward our reasons and demands, but neither the dealers nor the manufacturers responded to us voluntarily, not to mention any sincere apologies." Mr. Chen said that he was very enthusiastic before buying a car, but he adopted "delaying tactics" when the vehicle went wrong. The practices of dealers and manufacturers will not only make the majority of Tengshi car owners feel chilling, but also discourage other consumers.

　　Commitment to the market

　　Recently, several important news in the automobile market have been hotly debated by the majority of car owners:

　　First, Mitsubishi Motors intends to compensate the 625,000 car owners involved in the "fuel consumption gate" with a compensation amount of $1,000 per person, and the resulting taxes and fees will also be paid by Mitsubishi Motors.

　　Second, Dongfeng Honda decided to recall 1.03 million vehicles from July 31, 2016, because there are defects in airbags, which may bring safety hazards to passengers;

　　Third, SAIC-Volkswagen decided to recall nearly 150,000 cars from June 24, 2016, because there is a hidden danger of overheating failure of the car lamp fuse.

　　Earlier, relevant data showed that in May this year, a total of 12 domestic brands of multiple models issued a recall notice, with a total of more than 2.26 million vehicles, a record high in the same period. Among them, Aston Martin, Maserati, Lexus, Mercedes-Benz and other famous cars are involved.

　　"No car manufacturer dares to make a 100% quality guarantee, and millions of luxury cars are no exception." The insiders believe that under the current situation that people pay more and more attention to automobile safety, some automobile manufacturers dare to face up to product quality problems and take responsible measures, and their market credibility will be further enhanced.

　　Hearing about these bold measures taken by car companies, Mr. Chen felt that the attitude of Tengshi dealers and manufacturers was unreasonable. In Tengshi Service Manual, the warranty clause clearly stipulates: "During the warranty period and the three-guarantee period, if DENZA‘ Tengshi brand family car products have serious quality problems, you can handle quality assurance matters such as repair, replacement and return according to relevant national regulations."

　　Previously, the Provisions on the Responsibility for Repairing, Replacing and Returning Household Automobile Products promulgated by the State Quality Supervision, Inspection and Quarantine at the end of December 2012 also clearly pointed out that "in order to protect the legitimate rights and interests of consumers of household automobile products and clarify the responsibility for repairing, replacing and returning household automobile products (hereinafter referred to as" three guarantees "), household automobile operators shall not deliberately delay or refuse consumers’ requirements for three guarantees that meet these provisions without justifiable reasons".

　　The "Regulations" further clearly stipulates that "if serious safety performance failures have been repaired twice, and serious safety performance failures have not been eliminated or new serious safety performance failures have occurred", "if consumers choose to replace or return, the seller shall be responsible for replacing or returning".

　　"The General Administration of Quality Supervision, Inspection and Quarantine issued this Regulation a few years ago, mainly for fuel vehicles, and there are no specific provisions for new energy vehicles." A lawyer from the Lawyers Group of China Consumers Association believes that for pure electric vehicles, battery failure is a "serious safety performance failure", and dealers should pay attention to and properly handle Mr. Chen’s appeal.

　　Experts believe that with the rapid improvement of people’s living standards, China’s automobile industry has developed rapidly, but overall, the current automobile market is still competing in the low-end market. Thousands of joint venture brands and foreign brands have made a fortune in the China market, while a handful of independent brands are still slow.

　　"The vast majority of consumers are willing to choose foreign automobile brands, mainly because the quality of others is better. They not only dare to make commitments to consumers, but also dare to take responsibility and actively practice their commitments." Relevant experts believe that the domestic automobile industry should strive to keep up with market changes, provide detailed services to consumers and promote the healthy and sustainable development of enterprises.

　　Only when you are stable can you achieve far-reaching goals.

　　Judging from the global trend, new energy vehicles are the general trend. In China, the new energy automobile industry has been regarded as one of the strategic emerging industries focused on national development, and favorable stimulus policies such as subsidies for new energy vehicles and charging piles have been introduced frequently, which has injected great impetus into the development of the industry.

　　According to industry insiders, in first-tier cities such as Beijing, Shanghai, Guangzhou and Shenzhen, the sales of new energy vehicles have increased in the past two years, while in second-and third-tier cities, there are few. "According to incomplete statistics, three-quarters of the sales of new energy vehicles in 2015 were concentrated in cities where restrictions and purchases were imposed, and some consumers only bought new energy vehicles when they had to." The person said.

　　Ms. Li, who lives in Xicheng District, Beijing, said that she and her husband both participated in the car lottery in this city, and they failed for three consecutive years. However, children need to pick up and drop off in kindergarten, so the rogue had to take the road of new energy vehicles.

　　"The government supports new energy vehicles, shakes the number separately, and travels without limit. Just use it as a means of transportation." Ms. Li said that she and her family compared several new energy vehicles. Finally, because the children liked the appearance of Tengshi, they gritted their teeth and bought a fashion version. The price of the car was 369,000 yuan, after deducting 55,000 yuan from the central government subsidy and 55,000 yuan from the local government subsidy, the actual purchase price was 259,000 yuan.

　　"This price is really a bit high." Ms. Li believes that new energy vehicle manufacturers not only earn a lot of government subsidies without risk, but also sell cars at a high price. "When testing a pure electric vehicle with an original price of 230,000 yuan and a subsidy of about 100,000 yuan, the sales staff also said that this car is worth 40,000 yuan." Ms. Li said that the core of the new energy vehicle is the battery, but the battery is updated quickly, which means that the car also depreciates quickly.

　　After a period of use, Ms. Li realized the inconvenience of new energy vehicles. The first is charging. Because there is no fixed parking space in the community, it is impossible to install charging piles, while the charging piles in some public parking lots are either occupied or out of order. "When there were dozens of kilometers left, I began to worry about charging. There was really no way, so I ran to the 4S shop to charge."

　　Judging from the charging time, a car needs to be full, ranging from more than 2 hours to more than 6 or 7 hours. "It’s not like a fuel truck. It takes a few minutes to refuel." Ms. Li believes that for new energy owners, charging is also a kind of time investment, and it can’t be as free and easy as fuel owners.

　　From the cruising range, most of the mileage advertised by various new energy vehicles have a certain amount of water. "Tengshi’s advertisement says,’ achieve a cruising range of up to 300 kilometers’, but most cars can only drive to 260 kilometers; On the weekend, my friend invited me to visit Gubei Water Town. When I saw that it was 140 kilometers one way, I had to give up. " Ms. Li said that compared with fuel vehicles, the travel radius of new energy owners is greatly limited. "Going to the suburbs to see the flowers and flowers is a luxury."

　　Since the beginning of this year, the relevant ministries and commissions of the state have carried out investigations on "fraudulent compensation", which has affected the nerves of the entire new energy automobile industry. Since 2009, the Ministry of Finance has made a decision to give subsidies to the new energy automobile industry, and give corresponding subsidies according to the cruising range. In 2015, the state and local subsidies for new energy vehicles exceeded 30 billion yuan, but several billion yuan of them were tricked into the bag by enterprises.

　　Relevant experts believe that the "cheat to make up the door" in the new energy automobile industry is mainly to make a fuss about batteries, which can be described as a variety of tricks, but the investment in battery research and development is not enough. In this regard, Liu Xinwen, general manager of Chery New Energy Vehicle Technology Co., Ltd. also admitted that "battery technology has become the biggest shortcoming of new energy vehicles in China."

　　The "vote with your feet" market is the best tester. For Tengshi, which is known as "having German car-making technology and advanced battery power technology", it is also "not looking at advertisements, but looking at the curative effect". Data show that from January to April 2016, the national sales volume of electric vehicles was 38,472 units, the sales volume of Beiqi E-series electric vehicles was 792 units, and Tengshi sold 667 units.

　　"Occupy the weather, location, people and advantages, but the sales volume is so bleak, which will become the biggest crisis of Tengshi." Song Nan, a senior commentator in the automotive industry, believes that once the Tesla 3 with a price of 350,000 yuan is successfully localized and Toyota, GM and Peugeot Citroen quickly catch up, it will bring a fatal blow to Tengshi.

　　"The tide receded and I didn’t know who was swimming naked. In the next 10 years, if the state cancels the preferential policies for new energy subsidies, how should China new energy vehicles face market competition? " Zhu Jun, deputy director of SAIC Passenger Car Technology Center, pointed out that the core technology is a difficult and breakthrough point in the development of new energy vehicles, and efforts must be made on core technologies such as batteries to promote the healthy development of the new energy vehicle industry.

If you want to find a model with the top configuration in the price range of 200,000, it should be the Extreme Yue 01. Whether it is the world’s first Qualcomm 8295 chip, or the world’s first application of the 35.6-inch 6K true integrated screen, or even the AI ? ? big model getting on the bus, the Extreme Leap 01 has reached the ceiling level.

However, there is another voice that the configuration of Extreme Yue 01 is really high and the corresponding price is also high, which is not as cost-effective as Zhiji LS6.

So, what is the smart price ratio of the two cars? Whether the price of the high-configured Extreme Yue 01 is inflated, and whether the low-priced Zhiji LS6 can bring a satisfactory experience. Today, we will talk about it for everyone.

Let’s start with the price. The official starting price of Zhiji LS6 is 229,900 yuan, and the official starting price of Extreme Yue 01 is 249,900 yuan. After using the official car purchase rights of 70,000 yuan, the equivalent price of Extreme Yue 01 is almost 230,900 yuan. In terms of price, Extreme Yue 01 is more expensive than Zhiji LS6 in 1000 yuan.

Smart cabin comparison: I spent more 1000 yuan, bought top chips and a 35-inch 6K big screen.

What configuration can I buy if I spend more money on 1000 yuan? Let’s start with the smart cockpit panel.

The ultra-Yue 01 is equipped with Qualcomm 8295 chip, and its dual NPU computing power is as high as 60TOPS, which is comparable to the latest Qualcomm Snapdragon 8GEN3. Zhiji LS6 is equipped with Qualcomm 8155 chip, which is the product of the same era as the 855 chip of Qualcomm mobile phone terminal. Their performance is close, and their computing power is only 7TOPS. That is, one 8295 chip is worth eight Qualcomm 855 chips. With such sufficient computing power, you can ensure that the ultra-01 will not be stuck for 10 years.

Not only that, the ultra-over 01 intelligent cockpit supports immersive 3D visual interaction effects, which meets the full-screen, dual-screen and three-screen arbitrary partition experience, and all kinds of interactions such as dragging, zooming and three-finger operation are not smooth, and the fluency exceeds that of mobile phones. As for Qualcomm 8155, the computing power of this chip is not strong, and most models equipped with this chip have been stuck in the new car period, let alone used in the future.

Since the second half of 2023, the integrated screen has become the mainstream configuration of high-end smart cars. However, there are many doorways for integrated screens. Extreme Yue 01 is equipped with a 35.6-inch 6K true integrated screen, and the whole screen is seamless, which perfectly cures the obsessive-compulsive disorder of the game party and the film party. In terms of interactive experience, the intelligent cabin of Extreme Yue 01 supports a variety of third space modes, including movie viewing hall, game hall and KTV. This space is "suspended" on the water surface. When the finger slides on the water surface, it will produce a real-time 3D dynamic effect of "waves moving with the hand", as if the virtual space is at the fingertips.

At the same time, the details in different modes make the intelligent cabin full of immersion. For example, in the game hall mode, the customized version of Wild Racing not only shows the visual impact brought by the 8295+6K integrated large screen, but also perfectly calls the electric air outlet, ambient light, vehicle sound system and seat belt pre-tightening, just like a real driving competition. It is these details that make the smart cockpit experience of Extreme Yue 01 smoother and more immersive.

The integrated screen of Zhiji LS6 is made up of multiple screens. As long as the screen is powered on, it will light up the huge black border in the splicing area. If you are the main driver of Zhiji LS6, you can see that the main driver’s screen and the co-driver’s screen are divided into two by an ultra-wide border. If you want to play a full-screen game, you can only play it in the main driver’s car, and the auxiliary driver’s screen will completely ignore any game needs of the main driver.

The reason why Zhiji LS6 uses splicing screen is because it cuts off the 8295 chip with higher cost and uses the 8155 chip with lower cost. This chip cannot support 4K resolution because of its low computing power, and if the resolution of the integrated screen is lower than 4K, the clarity and fineness will be greatly reduced. Zhiji LS6 can only use splicing without increasing the cost.

The experience of the car system determines the upper limit of the intelligent cockpit. Due to the strong computing power of Qualcomm 8205 chip, Extreme Yue 01 took the lead in fully localizing the speech AI algorithm. The full-end speech recognition speed of off-line speech is as fast as 500 ms, and the end-to-end speech response speed is within 700 ms.. The voice ability of Extreme Yue 01 has completely got rid of the dependence on network signals. It will not become "artificial mental retardation" in weak or broken network environments such as tunnels and basements. In contrast, because the chip computing power of Zhiji LS6 is not enough, voice dialogue can only be realized in areas with networks.

In terms of the advanced configuration of the cockpit, Extreme Yue 01 is more sincere than Zhiji LS6, including the multi-directional electric adjustment of the steering wheel, four-door electric adjustment, rear multimedia screen, three-zone automatic air conditioning, rear privacy glass and other configurations that can experience advanced feeling.

Comparison of intelligent driving: spend more on 1000 yuan and buy advanced intelligent driving that can be opened in the whole country by pure self-research

The second biggest killer of the two cars is smart driving. In terms of intelligent driving, Extreme Yue 01 needs to be equipped with high-level intelligent driving, and the price after the selection is 230,900 yuan. Zhiji LS6 is standard. The difference between the two is mainly in experience. Extreme Yue 01 adopts Baidu’s pure self-developed high-order intelligent driving scheme, providing high-speed NOA+ NOA+AVP unmanned autonomous parking in urban areas, and the whole set of intelligent driving is ready to use without waiting.

Although Zhiji LS6 provides high-speed NOA and urban NOA, all models can’t use urban NOA, and high-speed NOA only opened nine cities in half a year. Moreover, because the intelligent driving of Zhiji LS6 is provided by a third party, the OTA upgrade is very slow and the bugs keep on.

Finally, let’s briefly describe the mechanical properties and three-electricity warranty of the two cars. There is no need to worry about the mechanical performance of Extreme Yue 01. After all, there is no weakness in the vast platform of SEA, and both the previous Extreme Krypton and Volvo can give consideration to sports and comfort. The four-wheel drive model also provides a high-power motor with a maximum power of 400 kW and a peak torque of 686 Nm. The acceleration per 100 km is only 3.8S, and it supports 0.4s lightning to switch the four-wheel drive mode, which can improve the cruising range of CLTC under comprehensive working conditions of 34 km.

It’s worth mentioning that you can still enjoy the welfare package of double 11 wheel hub when you buy Extreme Yue 01 now. The original price of the 21-inch wheel bag is 10,000 yuan, and now you can enjoy four 21-inch wheels, four 21-inch high-end tires and four sets of Brabo’s advanced brake calipers for only 2,000 yuan. Let’s just say that this kind of welfare is only a second. The driving quality of Zhiji LS6 is not limited by the "platform", and the chassis in sports mode is too hard and unfriendly to passengers, and the chassis in comfort mode is too loose and the driving quality is average.

In the aspect of fast charging and recharging, the charging power of Extreme Yue 01 can reach 240KW, and the maximum charging power of Zhiji LS6 is only 105KW, although it does not have 800V fast charging. In terms of charging time, it only takes 30 minutes for both the 71.4kWh battery and the 100kWh battery of the Extreme Yue 01 from 10% to 80%, and it takes 30 minutes for the Zhiji LS6 even from 30% to 80%.

Vehicle comparison: Spend more 1000 yuan, enjoy lifetime warranty and 2 years free charging.

In terms of car purchase rights and warranty, Extreme Yue 01 provided more than 70,000 yuan of car purchase rights, including 19,000 yuan of listing rights, as well as 15,000 yuan of optional fund, lifetime warranty of vehicle and Sanpower, two years of free charging, and six months of advanced intelligent driving experience.

In contrast, Zhiji LS6 even reduced the basic vehicle and the three-power lifetime warranty. If you want to enjoy the lifetime warranty of the whole vehicle on Zhiji LS6, you need to pay 6880 yuan, and you need to pay 9880 yuan to enjoy the lifetime warranty of Sandian, totaling 16760 yuan.

I think everyone should be very clear about this. Although Zhiji LS6 is cheaper than Extreme Yue 01 in 1000 yuan, it needs to spend 16,760 yuan to enjoy the warranty of the whole vehicle and the three electric appliances. As for Qualcomm 8295 chip, 35.6-inch 6K integrated screen, out-of-the-box high-order intelligent driver, four electric doors, two-year free charging and other hard-core configurations, it is needless to say.
