Beginners on the road may be at a loss in the face of difficult scenes such as narrow road sticking and turning around in place. Don’t worry, your car will automatically "pass"; When the city is congested, the car will automatically adjust (shock absorber, and at the same time control the opening of the switch or the braking force to cooperate), so that bad experiences such as starting to look up and nodding the brakes will no longer occur; The road ahead is sharp, and the car senses it earlier than you do. Steering, braking and suspension work together to reduce the turning radius, making the turning safer and more comfortable …

If the smart car is compared to a person, then the car also needs a smart "cerebellum", that is, the vehicle central coordinated motion controller (VMC) to dominate the whole body movement. As we all know, the brain is an organ that regulates the body’s functions and controls people’s movements and feelings, while the role of the cerebellum is to regulate muscle movements and maintain the balance of the human body. The cerebellum feeds back the information from the exercise to the brain, thus playing the role of regulating and correcting the exercise. The "cerebellum" of the intelligent chassis is not simply executed after receiving the instructions from the central computing and decision-making unit "Brain", but comprehensively considers the current application scenarios, optimizes the handling performance and ride comfort on the basis of ensuring vehicle safety, and then distributes the instructions to steering, braking and suspension, and finally realizes the coordinated control of six degrees of freedom (front and rear, left and right, up and down) in X, Y and Z directions, "muscle" and ""

In the next three years, SAIC will devote itself to building a brand-new "scientific and technological life". Including "intelligent brain", "agile body" and "strong heart". Among them, the "agile body" is the first to achieve a breakthrough in the "VMC technology of the whole vehicle", which keeps the vehicle body stable in different driving modes and various road conditions. It is reported that VMC will be first applied to the new Zhiji car next year. At present, SAIC’s intelligent solution integrating people, vehicles and environment is undergoing research and development, testing and verification.

Chassis by wire or smart car
The last piece of "puzzle"

In the new electronic architecture, the automobile execution system is also undergoing changes. From traditional chassis to electric chassis, and then to intelligent chassis, automobile chassis is welcoming brand-new changes.

Vehicle control is nothing more than longitudinal control represented by braking, lateral control represented by steering, and suspension control represented by up and down, which corresponds to six degrees of freedom of automobile movement. In order to meet the strict requirements of faster response speed and higher control accuracy of automatic driving, intelligent chassis needs brake, steering and suspension components by wire, and intelligent chassis has also become a wire-controlled chassis.

Chassis-by-wire system transmits the driver’s operation command to the actuator through the electronic controller, replacing the connection and execution from the traditional mechanical structure such as steering wheel and pedal, so it has the advantages of high precision, high safety and high response speed. By controlling the chassis with digital signals, the mechanical decoupling of the control system and the execution system can be realized. The drive-by-wire chassis can not only meet the requirements of higher-level automatic driving, but also enrich the imagination space of the intelligent cockpit and bring a safer and more comfortable driving experience to the occupants.

The chassis by wire mainly includes three core components: brake by wire, steering by wire and suspension system. Among them, brake-by-wire can not only meet the requirements of rapid response of automatic driving, but also meet the rigid requirements of energy recovery and increasing cruising range of new energy vehicles, and the market penetration rate is rapidly increasing. At present, the electro-hydraulic braking EHB system has been widely used in high-end pure electric vehicles. Although additional safety redundant equipment is needed, the intelligent Two-Box scheme is still more common in the short term, and the penetration rate of the intelligent One-Box will be significantly improved in the next few years.

Steer-by-wire steering is a rigid demand in the intelligent driving stage, which is gradually emerging. At present, it is in the stage of research and development verification and just getting on the bus, and it will also become a technical hotspot in the next few years. In the next 10 years, the penetration rate of steer-by-wire will reach 50%.

Since the beginning of this year, the air suspension system has been put on the market with some models, and the market popularity has also climbed once.

From the reality, with the acceleration of intelligent by-wire control system in smart electric vehicles to improve the competitiveness of brand models, by 2025, the domestic smart chassis market is expected to expand rapidly, which is expected to reach more than 50 billion yuan. Among them, the technical reserve of brake-by-wire is relatively mature, and the market is expected to grow at a compound annual growth rate of 34% from 2022 to 2025; In the next 4-5 years, the improvement of its assembly rate will provide a core increment for the smart chassis market, while steer-by-wire and air suspension are expected to enter the pre-assembly lead-in period in 2025.

Cross-domain fusion
Flexible deployment

From a technical point of view, at present, there is a trend of integration of various systems of automobiles, such as intelligent cockpit and intelligent driving, which are being integrated across domains. Zhang Ying, president of Bosch Chassis Control System in China, said that compared with the traditional chassis control system, in which all components are relatively independent for longitudinal, lateral and vertical vehicle dynamic control, VMC can adapt the chassis that was basically "just for itself" to the trend, and integrate the functions of transmission system, driving system, steering system and braking system into multiple systems, which greatly improves the vertical integration ability of chassis development, and can be flexibly deployed in pairs.

Steering and braking integration. It is very difficult for ordinary drivers to slam the steering wheel or make a big correction if they turn a corner on the icy road. When steer-by-wire and brake can be combined, the steering wheel angle and brake controller of steer-by-wire can be controlled in coordination, and the brake and actuator of steer-by-wire are integrated. Ordinary drivers can turn with the help of technological innovation, without worrying about oversteering or understeering, avoiding obstacles successfully and easily turning corners smoothly.

Brake and suspension fusion. Suspension system should not only meet the requirements of comfort, but also take into account the requirements of handling stability. Comfort is also related to the braking system. If the braking is too urgent, there will be phenomena such as braking nodding and unstable control. Comfortable braking function makes you an "old driver" in seconds. Through the precise software control of the system, a part of the braking pressure can be released smoothly in an instant before the vehicle stops, which can greatly alleviate the vehicle nodding and ensure the vehicle to stop very safely.

Integration of braking and power system. When the car starts on smooth roads such as snow and ice, the driving wheels may slip and the direction will be out of control, which will lead to danger. The driving torque vector control and braking control are combined with each other, and the acceleration potential of the vehicle is fully tapped, the curve limit is exerted and the dynamic response is optimized through the optimal distribution of axle or wheel torque.

Integration of VMC and ADAS. In order to meet the richer functional experience in NAD autopilot scene, the chassis needs to provide a bearing platform for autopilot system, cockpit system and power system. In the NAD autopilot scenario, VMC can integrate four-wheel drive distribution, brake-by-wire and variable suspension functions to maximize the dynamic performance of the vehicle, while supporting high-level autopilot scenarios. Through FOTA upgrade, it can be flexibly upgraded and quickly iterated.

Safety and comfort
Have your cake and eat it.

As a safety component, intelligent chassis has the highest functional safety level requirements. Functional safety is the core requirement of intelligent chassis and autonomous driving development. If the high-order automatic driving system comes, redundant braking and fail-safe will become the most important. Only on the basis of safety can driving be pleasant, comfortable, agile and personalized.

When the smart car develops to L3 or above, the driver will no longer control the car for a considerable part of the driving process, and the main responsibility of driving has changed from the driver to the system itself, which brings great challenges to the performance and safety of the whole chassis. For the drive-by-wire chassis, the most important requirements are safety and redundancy, and redundancy is also safe in essence. VMC has two backup schemes of independent actuators. When the main controller fails, the redundant controller takes over, which can systematically reduce the risk of failure of key functions.

The intelligent chassis is divided into two important parts: one is the chassis execution part, which realizes the coordinated control in X, Y and Z directions and the coordinated wire control optimization; Second, the chassis domain control system, based on the advantages of strong hardware and high performance chassis, further realizes the whole domain fusion control and rapid iteration of chassis through experience drive.

With the development trend and evolution of centralized electronic and electrical architecture, chassis control will be promoted to the concept of "domain". Combined with the chassis hardware system, the intelligent chassis domain controller can comprehensively design and adjust the chassis comfort and handling.

VMC can uniformly adjust and control air spring height, shock absorber damping, electronic parking and other functions. The controller detects the vehicle state through the signal received by the sensor, determines the optimal parameter instruction according to the algorithm or control strategy, adjusts the spring stiffness and damping state of the shock absorber, and increases the correction of pitch and roll to enhance the control of the vehicle body. For example, when driving in the field with poor road conditions and encountering a protruding obstacle in front, VMC system will "command" the air spring to raise the height of the car body, and at the same time adjust the electric shock absorber to make the vehicle smooth. In the face of bumpy roads, the system will also use compensation braking to alleviate jitter.

Thanks to VMC, after adjusting a large number of key components such as tires, air suspension and steering system, each car realizes the combination of comfort and handling, and develops various driving modes such as sports, comfort and energy saving according to road conditions and driving habits of users to meet the individual needs of users. At the same time, VMC relies on continuous collection and identification of users’ personalized driving data, and provides driving experience that meets users’ psychological expectations through human-vehicle interaction and self-learning iteration.

Different routes
"Zero" requires cooperation.

The Roadmap of Intelligent Chassis Technology for Electric Vehicles establishes the development goal of intelligent chassis, and the overall goal is that by 2030, intelligent chassis will meet the requirements of first-class products and leading technology. "The next 10 years will be a major strategic opportunity period for China’s intelligent chassis technology innovation and industrial development." Li Jun, then chairman of China Automotive Engineering Society, pointed out at the 2023 Electric Vehicle Intelligent Chassis Conference. At the same time, the intelligent chassis industry has also entered a critical stage of technical competition. Among them, the chassis domain controller has become a battleground for intelligent chassis development.

In the past, the international Tier 1 controlled the core of chassis control technology and provided "black box" chassis solutions for car companies. Many car companies, especially China brands, are highly dependent on suppliers’ development support, and the development time is long and the constraints are high, resulting in the lack of deep-seated chassis function integration development ability of the main engine factory, which makes the vehicles only meet some simple basic driving experiences, with few extended functions and relatively single driving experience.

On the one hand, with the rapid launch of new models, car companies urgently need to change the current situation. In the view of some OEMs, the high integration of software and hardware and cross-domain integration control ability are the core competencies that car companies must have in the era of smart cars, and they must be in their own hands. At present, some OEMs, such as BYD, Ideality and Weilai Automobile, have started full-stack self-research in this respect, and tend to plan chassis domain, convergence domain and other architectures, and lead the development of application software, and also put forward the requirements of "white box" delivery software for suppliers.

On the other hand, the international Tier 1 will obviously not give up the current market interests. Bosch China said that ABS and ESP are one of Bosch’s main products at present, and we are taking smart chassis as our next goal. ZF and Jidu have jointly developed the next generation of intelligent chassis technology to support automobile robots to "move freely".

With the continuous upgrading of R&D technology, coupled with the advantages of stable supply chain, rapid development and market response, China suppliers are likely to catch up with others. Among them, since the mass production of One-box line control products in 2021, Bethel has carried a number of models to the market. At the same time, local start-ups such as Nathan, Tongyu, Likun and Grubo have successfully mass-produced brake-by-wire products based on the Two-box scheme, achieving a new breakthrough in localization.

There are various indications that in the field of intelligent chassis, especially in VMC, the boundary between OEMs and suppliers in the technical field has become blurred, and the technical route of domain controllers will also be "contended by a hundred schools of thought". Borders are often fought out, but at the same time, there are opportunities for cooperation in competition.

Zhang Jinhua, chairman of the China Society of Automotive Engineering, suggested that we should advocate adhering to the sense of cooperation, deepen the whole-scale cooperation, cross-border cooperation and international cooperation, and deepen the synergy between the industrial chain.

Although the full-stack self-developed chassis domain control allows the main engine factory to master more autonomy, it also needs to consider the cost and efficiency. The drive-by-wire chassis products need a lot of adjustment work and the full cooperation of the parts manufacturers. The advantage of the main engine factory is to integrate the parts control provided by suppliers. In the future, the direction of cooperation between the two parties is likely to be to jointly define the system architecture and development design, and all parties will contribute their own "points" and unite to achieve a "breakthrough". Specifically, the supplier may only be responsible for providing the hardware and doing the underlying driver, and then open the control right to the OEM to do in-depth joint development with the OEM, so as to improve the development efficiency and software reusability, speed up the iteration and reduce the cost.

[Those things in China] Foreign "online celebrity" is optimistic about China’s business opportunities. US media: Keep up with the trend and tap high-quality content to be competitive

  China Daily Online, January 11th In recent years, China’s "online celebrity" economy has grown exponentially. According to the data released by consulting organizations, the number of "online celebrity" with more than 100,000 fans in 2017 increased by 57.3% compared with 2016. For China, a market with 1 billion mobile phone users, foreign "online celebrity" have also found huge business opportunities. Nowadays, more and more foreign faces appear on various social platforms in China.

  According to the American news website The China First News, in 2018,’s "online celebrity" economy was about $14 billion (about 96 billion yuan). The huge fan base and lucrative advertising fees have made a fortune for domestic "online celebrity", and now foreigners are competing to join in the fun. In order to stand out from the fierce competition, foreigners follow the trend and meet the needs of China fans to the greatest extent by providing distinctive content.

  Launch its own brand

  According to the article, foreigners who were famous in China in the past were either international celebrities themselves or lived in Asia. The latter can attract people’s attention for two reasons. First, it is as unconventional as a "bearded spice girl" who has been a wrestler; The second is to become a China hand like a mountain.

  Nowadays, a new type of foreign celebrities has begun to rise. They have often become popular on social media abroad. Although he can only speak a few simple Chinese, the English level of young people in China has improved, and fans often translate subtitles spontaneously, which attracts the attention of many fans in China. In short, these content creators always have something that interests China audiences.

Gavin’s screenshot of Weibo

  Gavin Thomas, an 8-year-old "smirk boy", is an example. In many Asian countries, in order not to offend people or ease the embarrassing atmosphere, people always squeeze out a fake smile. Gavin’s "embarrassed and polite smiles" aroused people’s resonance and made him gain a lot of fans.

  In July 2018, Gavin opened a Weibo account, and the number of Weibo fans has reached 1.95 million, exceeding his fans on Facebook, Twitter and YouTube. Gavin has cooperated with Taobao and launched a series of co-branded products, such as sweaters with his head, which is a change in the way foreign online celebrity realized in China.

  In 2018, there seems to be a new trend among foreign bloggers. They should not only produce high-quality content, but also integrate themselves into all aspects of life in China and form their own distinctive cultural brands. In 2019, foreign "online celebrity" may pay more attention to the interaction with netizens in China, create an influential independent brand in China and realize its realization.

  Multi-platform operation

  The article points out that WeChat and Weibo are the largest social media platforms in China. In addition, social media platforms such as Youku Tudou, Tik Tok, Xiaohongshu, Meipai, and Bili also have many users.

  Previously, foreign "online celebrity" bloggers were mainly active in WeChat and Weibo, but in 2018, a short video boom started in China, with domestic bloggers shooting short videos on various platforms, and foreign bloggers also followed the trend.

  Some of them hang out on short video platforms such as Li Li, some settle in Xiaohong’s writing product evaluation, and some specialize in making funny videos. Some foreign bloggers even have fans in Zhihu. Marie from England can speak fluent Chinese. On social media in China, her name is Tan Manru. Going to Zhihu and making videos made her famous in China.

  In 2015, Tan Manru and China’s popular Chen Han Siri filmed a video, which was posted on Mile Mile, Youku and YouTube, and the number of hits exceeded 37,000. The video released by Chen Han Siri focuses on letting China audience know about western culture.

  When answering questions from Zhihu, Tan Manru often gives her own unique views on cultural differences and explains her understanding of China culture in a humorous way. She won more than 130,000 endorsements and 41,580 collections on Zhihu. After becoming popular on Zhihu, Tan Manru also began to enter other platforms. She settled in the knowledge question-and-answer platform "Be a little better" to provide paid question-and-answer service for fans.

  In 2018, social media in China flourished, and various platforms emerged one after another. Especially with the rise of short videos, creating richer content to help major platforms attract users has become a must for foreign "online celebrity".

  Seek institutionalized operation

  The article thinks that 2018 is the era of short video, with second shot, Aauto Quicker and Tik Tok leading the way. The video ecosystem has also changed in other ways.

  However, as foreign "online celebrity" clustered in China content market, more and more people encountered difficulties in cross-cultural communication and entering the China market. At this time, MCN(Multi-Channel Network) operation mode shows certain advantages. Slivki Show, a Ukrainian video blogger on YouTube, is an example of the cooperation between content creators and MCN organizations. Slivki Show will share interesting scientific experiments and life tips, such as how to squeeze 2 liters of orange juice from an orange. It has more than 1 million fans and 191 million video hits on Youtube. In 2017, Slivki Show settled in Weibo and added Chinese subtitles to the video.

  MCN institutions explore and sign talents, and then push them to various media platforms. Yoola, a MCN company working with Slivki Show, manages more than 72,000 channels on YouTube. Yoola localizes the channels that it thinks are suitable for China audiences.

  People may not have noticed that many foreign entertainers have settled in China social media websites or cooperated with MCN organizations. American model Carly Klaus settled in Little Red Book in May. Actor Robert Downey Jr., singers Taylor Swift and Britney Jean Spears, basketball player Dwyane Wade all opened Weibo, and Radiohead of British rock band also used Weibo. Many of these people’s social media accounts in China are managed by the Fanstang of MCN. And creative rookies can cooperate with many small MCN organizations to localize their content in China market.

  The article points out that in the future, there will be more foreign "online celebrity" active on social media platforms in China, especially those YouTube foreign bloggers who have many fans. They won’t miss the market of China, and they will be more active in 2019.

Live broadcast with goods can not be consumed "trust"

  A number of online celebrity’s recent "tragic auction" incident caused widespread concern. They deliberately design scripts and words, and deceive well-meaning consumers through live broadcast and false marketing. Due to the huge amount involved, the social impact is extremely bad.

  Fake help to farmers, really bring goods. Selling miserable false marketing is indifferent to feelings, unreasonable to reason, and unacceptable to law. What needs to be reflected is that similar farce has been staged repeatedly, and there have been many criticisms on the Internet for a long time. Why can online celebrity, who is under the banner of helping farmers, repeatedly bluff and cheat?

  The cost of traffic fraud violation is low. A script, several actors, through fictional experiences on the Internet platform, can gain the sympathy of netizens, bring goods live openly, and even sell fake and shoddy products. This practice not only infringes on consumers’ right to know, but may also be suspected of constituting a crime. Low risk and huge returns have become the driving force for some live broadcast operators and online celebrity to take risks.

  Live broadcast with goods lacks rigid constraints. In recent years, online celebrity’s economy has developed rapidly. Under the commercial packaging, many anchors have become popular and quickly realized their traffic. Due to the profit-seeking nature of capital, shanzhai is in power and counterfeit goods are rampant frequently. This shows from the side that the live broadcast industry is developing rapidly, but the industry standards and norms that match it should also keep up in time.

  It is difficult to prove consumer rights protection. There are a large number of online celebrity scattered on major live broadcast platforms, and most businesses do not have physical stores. The duration of false propaganda is generally short, so it is not difficult to obtain evidence directly. It is difficult for ordinary consumers to trace the true source of goods, and it is even more difficult to prove online celebrity’s false propaganda. Under normal circumstances, only after the business is subject to administrative punishment can consumers complain with the punishment record.

  The chaos has been repeatedly banned, and the platform is hard to blame. In the pursuit of value that traffic is king, some platforms have become distribution centers for fake goods, which are full of labeled sales and fake and shoddy goods. In the long run, these platforms will overdraw the trust of consumers, leading to the gradual loss of users, and ultimately the loss will outweigh the gain. Therefore, in order to develop healthily in the long run, the platform should strictly filter user content and truly implement disciplinary measures.

  The auction and false marketing not only overdraw the goodwill of the public, but also corrupt the social atmosphere. Online celebrity should realize that the fan economy is a trust economy, and if trust is consumed wantonly, the consequences will be very serious once it is overturned. Since false marketing will cause harm to all parties, it is necessary to strictly investigate the live broadcast accounts that violate public order and good customs to defraud netizens, cut off traffic empowerment and illegal profit-making channels, and also clear the space for online consumption.

Talking about the development of hydrogen energy, the second international fuel cell vehicle conference was held in Rugao

  CCTV News:On November 9th, the 2nd International Fuel Cell Vehicle Conference was successfully held in Rugao, Jiangsu. The conference was hosted by International Hydrogen Fuel Cell Association (to be established) and China Automotive Engineering Society, and was undertaken by Nantong Municipal People’s Government and Rugao Municipal People’s Government. Nearly a thousand political elites and industry giants from more than 20 countries and regions attended the meeting.

  At the opening ceremony, Deputy Director of the High-tech Development and Industry Department of the Ministry of Science and Technology continued to read a congratulatory letter from Vice Chairman Chinese People’s Political Consultative Conference, Chairman of China Association for Science and Technology and Minister of Science and Technology Wan Gang. The congratulatory letter emphasized the strategic position and important role of developing hydrogen fuel cell technology in implementing the strategy of new energy vehicles and realizing the transformation and upgrading of the automobile industry. It also emphasized that the development of fuel cell vehicles must take the road of "innovative development and systematic promotion", and "cooperation, synergy and win-win" will be the fuel cell vehicle technology and industry for a long time to come. Fu Yuwu, Chairman of China Automotive Engineering Society, Chang Hexi, Secretary of China International Economic and Technological Exchange Center of Ministry of Commerce, and Deputy Director Guo Bie of the United Nations Development Programme Representative Office in China attended and delivered speeches.

  At present, environment and energy are common challenges facing the whole world. Hydrogen energy has become an important choice for international energy reform because of its ubiquitous and clean nature, and it is also the main direction of transportation energy transformation. Since the beginning of this year, several developed countries have announced the timetable for traditional fuel vehicles to withdraw from the historical stage, and well-known foreign automobile manufacturers have also acted accordingly. As one of the leading countries in the layout of new energy vehicles in the world, China has given sustained and high-intensity support to new energy vehicles, including fuel cell vehicles, in research and development, industrialization and application, and it is clear that mass production and large-scale demonstration application of fuel cell vehicles will be realized by 2020. In this context, the theme of the conference was "Integrated Development and Industry Win-Win". Experts and scholars from Dalian Institute of Chemical Engineering, Shenhua Group, SAIC Motor, Anglo American Resources, Hyundai Motor, Great Wall Motor and Honda Motor of Chinese Academy of Sciences shared and exchanged the latest development achievements in the field of fuel cell vehicles, and jointly discussed the commercial application of fuel cell vehicles.

  On the theme of "Rugao Hydrogen Energy and Fuel Cell Development and Application Practice", Chen Xiaodong, secretary of Rugao Municipal Party Committee, made a conference exchange. He said that Rugao is the only longevity town in the world located in an economically developed area, and the green ecology is Rugao’s greatest wealth, greatest advantage and biggest brand, and the hydrogen energy industry is highly compatible with Rugao’s green ecological concept. Since meeting hydrogen energy for the first time in 2010, Rugao has continuously paid attention to and developed hydrogen energy, and regarded the hydrogen energy industry as the key development industry in the "Thirteenth Five-Year Plan", mainly because the expectation of the development of hydrogen energy industry has strengthened Rugao’s confidence and determination to develop hydrogen energy, and the strategic consideration of future development has determined that Rugao must plan ahead and plan ahead. The affirmation and support of provincial and municipal leaders for Rugao’s hydrogen energy industry has increased the courage and motivation to move on. In recent years, Rugao has devoted itself to the research and development of hydrogen fuel cell technology, promoting the integrated development of fuel cells and automobiles, compiling a roadmap for the development of hydrogen energy in Rugao, demonstrating the application of fuel cell products, participating in the research and formulation of fuel cell technical standards, promoting the construction of fuel cell testing centers, researching and publishing the China hydrogen economic development index, and accelerating the implementation of hydrogen production projects, and has successively owned Nantong Baiying Energy, Zehe New Energy, Nantong Yaman, Shenhua Group, Jiangsu Qingneng and Nantong Ansi.It has become an area with early development layout of hydrogen energy and fuel cell automobile industry and high concentration of industrial chain enterprises in China. He said that in the future, the United Nations "hydrogen economy demonstration city" will be promoted as the starting point, and the national "first batch of hydrogen energy industrialization demonstration bases" will be the goal, and a good ecosystem for the development of hydrogen energy and fuel cells will be built with all efforts to explore the way for the politics, production, learning and research of the international hydrogen energy industry.

  In the high-level interview session, under the auspices of President Zhao Fuquan of Tsinghua University Automotive Industry and Technology Strategy Research Institute, Ma Jinhua, member of the Standing Committee of Rugao Municipal Committee, Xu Guo, member of the Standing Committee of Foshan Municipal Committee, Hehe Dayang, head of Toyota Technology, academician of China Academy of Engineering, Li Jun, chief engineer of China FAW Group Corporation, Mai Kaiwen, CEO of Ballard, Bruno Forget, President of Hydrogen Energy Company of Liquefied Air Division, Shouzhi Fujimoto, Minister of Hydrogen Energy Division of Iwatani Industry, and other political and business representatives.

  The conference lasted for 2 days, and on the second day, there were 4 special sub-conference venues to discuss and exchange topics such as "Market Application of Hydrogen Fuel Cell Technology", "Development and Application of Hydrogen Production and Hydrogen Storage Technology", "Fuel Cell Stack and Key Parts" and "Standards, Regulations and Testing Technology".

  The conference adopts the way of exhibition, paying attention to the on-site experience and interaction of the delegates. The latest fuel cell vehicles, such as Toyota, Hyundai, Honda and SAIC, were displayed centrally outside Rugao Automobile Culture Center, and at the same time, test rides and test drives were carried out. The delegates also went to Nantong Baiying Energy, Shenhua Hydrogen Station and other enterprises in Rugao Development Zone for technical visits.

Liars stare at the Tik Tok card collection platform to remind them not to be fooled.

  As the Spring Festival is approaching, many platforms have launched the activities of collecting cards and redeeming red envelopes, and the exchange of cards such as Fuka and Zanka among friends has also become the current trend. Unexpectedly, some scammers are also eyeing this "market". A few days ago, many netizens reported that in the process of collecting Tik Tok gold cards, they wanted to spend money to buy one from others because the gold card corresponding to the word "Fa" was not received, but as soon as the transfer was made, the other party was blacked out and lost contact. In response to this situation, the Beijing Youth Daily reporter learned from Tik Tok yesterday that it is not reliable to resell gold cards online, and the card collection page exposed by scammers is not consistent with the actual situation. "After the cards are collected, the buttons will change, so don’t be fooled."

  Weibo broke the news.

  Buying a Tik Tok "hair" card meets a liar

  The reporter of Beiqing Daily noticed that according to the introduction of related activities in Tik Tok, the top 1,088 people collected five gold cards corresponding to each word of "Make a fortune in China", and they could get a 10,000-yuan koi fish red envelope. As of 15: 30 on January 18th, 319 people had collected their gold cards.

  Wang Wei (not his real name), who lives in Hainan, saw someone posting the Tik Tok Card Collection page in Weibo on the 17th. The screenshot shows that the other party has collected six "Fas". As it happens, there is only one "hair" missing from the card I collected, so I contact the other party actively, hoping that the other party can share a "hair" with me. After Wang Wei passed the consultation in Weibo, the other party said that "fat" was rare and there were many people who wanted it. If they really wanted it, they needed to pay some money. After that, the two parties agreed that Wang Weixian would transfer money to 300 yuan, and the other party would share the card before giving it to 200 yuan, and added WeChat to each other to facilitate contact. However, after Wang Wei transferred money to 300 yuan via WeChat, the other party repeatedly shirked it on the pretext of poor signal on the road, delayed sharing the card, and completely blacked out Wang Wei after Wang Wei proposed to report to the police, and lost contact from then on.

  Wang Wei said that he had consulted the local police, but it was difficult to file a case only for 300 yuan’s losses. Therefore, Wang Wei left a message at the bottom of the other party’s Weibo that night, exposing the scam, hoping to prevent others from falling for it as much as possible. In addition to Wang Wei, many netizens also reported encountering similar scams: "I just got cheated by Tik Tok’s card issuance for 100 yuan, suffocating." "I was cheated by 30 yuan, and I didn’t have much money, but I was still angry."

  Netizen analysis

  10,000 yuan red envelope makes the competition more intense.

  In fact, many netizens are busy collecting blessings and praises. Compared with Alipay’s activities in Five Blessingg, why is Tik Tok’s "Year of Making a Rich in China" so popular that it is targeted by scammers?

  Meng Xi (pseudonym), who has participated in such activities for several years in a row, told the reporter of Beiqing Daily: "This year, Alipay, Tencent News, Aauto Quicker, Tik Tok and other platforms have activities, and it is still uncertain how many red envelopes other platforms will receive after collecting cards. Grab ‘ according to previous years; Dedication ’ Experience, the amount of red envelopes after the collection is not too high. In contrast, Tik Tok’s activity is to explicitly promise that the top 1,088 collected users will get 10,000 yuan in red envelopes, which is relatively large, and they have to be ahead of so many netizens in the country, so the competition is fierce, and some people are even willing to spend thousands of dollars to buy the most scarce ‘ Send ’ Card. "

  Journalist experience

  Claiming to be "delivered" but still charging.

  According to netizens, among the five gold cards in Tik Tok’s activities, the word "Fa" has the lowest probability. Many people are stuck in this card, and most scammers cheat on the pretext that they have extra "Fa".

  The reporter of Beiqing Daily searched yesterday and found that in the user comment area where they have already exposed their own redundant "hair" cards, many netizens left messages saying that they want to buy one. The reporter of Beiqing Daily contacted Mike (a pseudonym), one of the users who claimed to have extra cards. The other party said that he had an extra one, "which can be given to the right person at random".

  After the reporter of Beiqing Daily contacted his private letter, Mike said that there are too many people who want this card, and it depends on sincerity to decide who to give it to, and said, "You make a price first." When the reporter of Beiqing Daily offered to go out to 300 yuan to buy a card, the other party quickly sent a two-dimensional code for collection, requesting to transfer money first. When the reporter of Beiqing Daily asked "What if you don’t give the card if you give the money", the other party suggested that you can turn half first. The reporter of Beiqing Daily rejected this suggestion and asked the other party to leave a contact information that can ensure that he can be contacted, so as not to find someone when it is dark.

  After that, the other party sent a QQ account as a guarantee, and asked the reporter of Beiqing Daily to transfer money as soon as possible after adding him as a friend. The reporter of Beiqing Daily found that the relevant personal information in the QQ account it provided had been hidden, and the WeChat account associated with the account showed that "the account status was abnormal and could not be displayed".

  Tik Tok reminded.

  The page buttons will change after the cards are collected.

  The reporter of Beiqing Daily noticed that the gold card collection page provided by Mike showed that the cards he had collected ranged from 2 to 10, and the rest were consistent with the pages of users who had not collected all the cards. Some netizens suggested that if five cards have been collected, the red button "Increase the number of cards drawn immediately" at the bottom of the page should be changed into other words, and it is suspected that there are many screenshots of "hair" pages on the Internet. Some netizens reminded me that "10,000 yuan has to be sold in hundreds or dozens, and people are trying to figure it out." It is not credible when you listen. "

  Yesterday afternoon, the reporter of Beiqing Daily learned from the Public Relations Office of Tik Tok that according to the activity setting, users will automatically enter the stage of collecting diamond cards after collecting all the gold cards, and the page buttons will change accordingly. At the same time, Tik Tok’s public relations stressed that at present, the platform has released rumors about the online reselling of gold cards. "Remind everyone, don’t trust those online ‘ Selling cards ’ Or ‘ Cheats for selling flashcards ’ All the people are fake. "

  Chongqing Liangjiang New District, a State-level New District along the Yangtze River: "Half Mountain and Half City" Writing Green Development Road

  Zhongxin. com, Chongqing, May 15 (Reporter Han Lu) The water of the Yangtze River has given birth to life and civilization along the river. In the 679 kilometers that the Yangtze River flows through Chongqing, there is a shining "star" — Following Shanghai Pudong New Area and Tianjin Binhai New Area, Chongqing Liangjiang New Area is the third national development and opening-up area in China approved by the State Council.

  On the 14th, the second day of the "Beautiful China Yangtze River Tour Chongqing Station" activity, the delegation came to Liangjiang New District in Chongqing. Liangjiang New Area focuses on green smart cars, emerging electronic information and high-end equipment manufacturing. Here, a number of high-tech enterprises with environmental protection are stationed.

  "Ecological civilization construction is the key work of Liangjiang New Area. From production to life, all development and construction must adhere to ecological priority, eliminate pollution from the source, and once the plan is formulated, it must be unswervingly implemented to the end." The relevant person in charge of the Management Committee of Liangjiang New Area told the reporter that in recent years, Liangjiang New Area has completed more than 10 professional plans, achieved full coverage of the plans, and delineated the blue line, green line and ecological red line, providing a basic guarantee for protecting the mountains and water in Liangjiang New Area.

  On the same day, the reporter walked into the China Automotive Engineering Research Institute and Huaneng Liangjiang Gas Engine Factory in Liangjiang New Area to explore the green development road of Liangjiang New Area.

  Cars have already "entered the homes of ordinary people". With the consumers’ demands for automobile safety, intelligence, comfort and health, it is getting higher and higher.

  "Noise, vibration and safety can be said to be a concentrated expression of the quality of passenger cars." The person in charge of the State Key Laboratory of Automobile Noise, Vibration and Safety Technology of China Automotive Engineering Research Institute said that as the technical shortcoming with the biggest gap between independent brands and foreign brands, automobile noise, vibration and safety are also the most concerned and easily perceived performance of consumers.

  According to the person in charge, the State Key Laboratory of Automobile Noise, Vibration and Safety Technology, which belongs to China General Technology Group China Automotive Engineering Research Institute Co., Ltd., was established with the approval of the Ministry of Science and Technology in 2010. It is the only state key laboratory of automobile enterprises in the Yangtze River Economic Belt. Since its establishment eight years ago, the laboratory has focused on three aspects: automobile noise and vibration, automobile active and passive safety and automobile electronic control.

  According to reports, as far as scientific research conditions are concerned, the laboratory currently has the research and development conditions that reach the level of international first-class scientific research bases, and the related scientific research equipment and instruments reach 400 million yuan. Among them, the semi-anechoic room, full anechoic room, abnormal sound laboratory, multi-angle vehicle collision laboratory, trolley collision laboratory, crash dummy, 10m anechoic room and intelligent networked vehicle test demonstration area have reached the international advanced and domestic leading level.

  In the research of automobile passive safety technology in the laboratory, we not only focus on the research of common technologies in the field of automobile passive safety, but also provide a complete set of star-rated development optimization schemes for enterprises in the development of automobile passive safety vehicles and parts. In the field of passive safety of new energy vehicles, the collision protection technology of power battery pack is put forward, which provides a systematic solution for enterprise research and development and design.

  The person in charge of the laboratory revealed that at present, the laboratory has the world-class third-party collision test capability. It has the ability of vehicle-to-vehicle collision, real vehicle rollover test, pedestrian protection test and collision simulation test with different angles from 0 to 180.

  On the basis of the research on automobile safety and maintainability, the laboratory also cooperated with the insurance industry across disciplines to establish and publish the "C-IASI Test and Evaluation Procedure of China Insurance".

  In the water and soil industrial park not far from China Automotive Engineering Research Institute, a modern energy station is providing a steady stream of green power for the development of Liangjiang New District, which is Huaneng Liangjiang Gas Turbine Power Plant. Here, the definition of thermal power station is green, energy saving and environmental protection.

  When the reporter walked into the production area, he couldn’t see the traditional chimneys, couldn’t hear the roar of machines, and all kinds of pipes like cobwebs disappeared. The clumsy feeling of traditional factories was replaced by garden-style factories.

  According to reports, Huaneng Liangjiang Gas Turbine Power Plant has such a "beautiful" appearance, because the factory has put on a "coat" for the main buildings by transforming the appearance, which not only pursues fashion and beauty, but also has the functions of noise reduction and fire prevention; The appearance of the chimney adopts hotel-style design, which changes the hyperbolic cooling tower design of the traditional power plant, adopts mechanical ventilation tower, and is designed as an office building, with a silencing wall at the bottom, which makes the power plant "not like a power plant" & HELIP; …

  "Our gas turbine adopts a low-nitrogen burner and simultaneously builds a denitrification device. The emissions of pollutants such as sulfur dioxide and nitrogen oxides are far below the national standards." Bao Yong, general manager of Huaneng Chongqing Liangjiang Gas Turbine Power Generation Co., Ltd., said that after calculation, for every 100 million kWh of power generated, Huaneng Liangjiang Gas Turbine Power Plant can reduce nitrogen oxides by 22.2 tons, equivalent to the annual emissions of 37,000 cars; It can reduce the emission of sulfur dioxide by 63.4 tons, equivalent to the emission of 23,000 tons of coal; Reducing carbon dioxide emissions by 51,000 tons is equivalent to reducing carbon dioxide emissions by 13.36 tons per mu of forest, which is equivalent to planting 38,000 mu of trees.

  Liangjiang New Area has been using and exploring green energy and clean energy. Huaneng Liangjiang Gas Engine Factory is the first gas in Southwest China — The comprehensive clean energy station with steam combined cycle combined cooling, heating and power supply gives full play to the advantages of green, low carbon, cleanliness and high efficiency. The emission of sulfur dioxide, the main pollutant, is only one tenth of the national standard, and nitrogen oxides are less than half of the national standard, which has made contributions to energy conservation and emission reduction.

Che Baoluo, a Hong Kong actor, frequently makes hot searches. Please remember these licorice actors!


Special feature of 1905 film network "In Hong Kong, there are a group of actors called licorice actors.They will always be the back and side (supporting roles) in their lives.Because we are willing to be green leaves, we are called licorice actors. "Recently, the actor’s interpretation of "licorice actor" has been searched hot.



He has been in the business for 42 years, with more than 70 works and numerous classic supporting roles.But it seems that until today, the audience really got to know this lovely 63-year-old "little old man".


Che Baoluo frequently boarded hot search.


There are many "licorice actors" like Che Baoluo who are willing to be green leaves and achieve their roles.Today, let us get to know them again. The "ordinary" life of the supporting role is equally wonderful!


Paul Che

"If there are still people who need it at the age of 80, I am absolutely willing to serve."


"I have made more than 70 plays, some with names and some without names.""But the quality of an actor is that every play and every announcement must be completed in a professional spirit."It is this humble, elegant and particularly serious attitude that makes Che Baoluo numerous.



After 42 years in the business, Che Baoluo has left many memorable roles with his special appearance.The most popular works are "famous works".Jordan chaneditionThe Duke Of Mount DeerFat Buddhist monk in the middle school.Growing up with countless audiences is still talked about by people.



In the "golden age" of Hong Kong’s film and television circle, Che Baoluo also made numerous films.existMiracle, Death JudgeIn big movies, they all had guest roles.



However, how can I expect that things change, and after the climax, it is lonely.In 2003, the TV station offered him a renewal basic salary of only HK$ 2,000 per year.In order to make a living, he has received relief money and worked as a security guard, carrier and other handyman.At the most difficult time, even the mother’s funeral expenses could not be raised.Che Baoluo, who was in the trough, once sincerely lamented: It’s hard to climb to heaven, and it’s even harder to ask for help!



Nowadays, Che Baoluo’s job is to supervise the market, except occasionally taking on plays.It is his daily work to solve the problems of water, electricity and drainage, divert traffic and help the neighborhood.



Che Baoluo loves acting, and he also accepts that it is true to return to life.Just like his promise to the audience in front of the camera: "If you still need me at the age of 70 or 80, I am absolutely willing to serve."


In 2019, Che Baoluo starred in a short film.The old man and the dog


Wenbiao Huang

"I want to be an actor, not a star"


"If Brother Xiang is useful to Tengmou, Tengmou is willing to render his services."Many people know Huang Wenbiao through.Teng Yi, Xiang Shaolong’s sworn brother.


Huang Wenbiao is found in both the drama version and the film version of Qin Xun Ji.


He is also known as "Tai Tai Royal Bad Boy" because he is good at playing all kinds of "traitors" such as bullies, creditors and kidnappers.For example, Tianqi with a ponytail and earrings in "Sniper by School Police";The big ear hole in "Clean Government Action";The white-headed tiger in The Apostle 2 has left a deep impression on the audience.


Sniper by the school police


Huang Wenbiao paid no attention to the stereotype of "specialized debt collectors"."Hundreds of artists, it’s good to be the first to find a debt collector and the second to think of me."He said he didn’t envy the main characters. They may earn a lot of money, but it’s hard to do it all their lives.Just to be a supporting role in the third and fourth lines, there will always be a play, and it can be played all the time.



Returning to life, another important identity of Huang Wenbiao is an ordinary fisherman, who helps with transportation in a friend’s fish stall.It is not shameful for actors to sell fish part-time. "If you have hands and feet in Hong Kong, just do it."



For Huang Wenbiao, the happiest moment was when the audience recognized him and said: I like your play."I’m notgorgeousyoung manDon’t mind being a supporting role. I am an actor, not a star. "



"The joy of performing can’t be bought with money."


"I am’ Mai Bao’ Changqing Mai, and you can also call me Extraordinary Brother."Changqing Mai, 54, is used to introducing herself like this.The "extraordinary brother" he portrayed in "The Heroic Love of a Woman" won him the best supporting actor.In the internet age, this role has once again become popular and become a hot second-generation material.



In addition, Changqing Mai’s representative roles include the sand monk in The Journey to the West, You Tanzhi in Dragon’s Eight Branches, Zhao Junhao in Love with Thieves, and so on.



He has appeared in nearly 100 plays, and there are many classic works. However, Changqing Mai said frankly: In Hongkong, it is difficult to support a family by acting alone."Many older actors have to work several jobs to stick to this line."



For the sake of family livelihood, Changqing Mai once moved furniture, made publicity and opened a restaurant.During the epidemic, business was sluggish, and he personally delivered takeout.



In Changqing Mai’s view, life should go on, and acting dreams should also be adhered to."I really enjoyed playing an excellent role, and that feeling can’t be bought with money. That sense of accomplishment is something that another industry can’t give you. "



"It is this drama addiction that has made me do it for decades."


In 2014, 68-year-old Liu Jiang won the TVB Starlight Achievement Award.Honored guestAndy LauKindly call him "Lao Dou" (Dad), and their cooperation dates back to the 1982 TV series.Falcon.


Andy Lau introduced Liu Jiang as follows: In the past 30 years, Mr. Liu Jiang has made more than 100 dramas for TVB.



Many mainland audiences may not remember Liu Jiang’s name, but they will always remember his wonderful performance in a Jin Yong play.In his 56 years as an artist, Liu Jiang has appeared in Jin Yong’s dramas for 17 times, which is the only Hong Kong drama bone that has performed Jin Yong’s martial arts.



In the 83rd edition of Legend of the Condor Heroes, he is the ambitious Yan Hong Honglie;96 editionthe legendary swordsmanIn the middle, he is Xiang Wentian, who is known as the "Heavenly King Lao Zi";In the 97th edition of Dragon and Eight Branches, he became the abbot of Xuan Ci.There is also the 84 th edition of "Swordsman"rivers and lakesThe wind is clear; In the 94 th edition of The CondorironwoodReally, Prince Kang in the 98 version of The Duke Of Mount Deer. …


Liu Jiang plays Temujin in the 94th edition of The Condor.


The treatment of "licorice actors" in Hong Kong entertainment industry is not high, and Liu Jiang once bluntly said:"I enjoy acting myself, but it’s hard to eat."



In order to support his son’s high tuition, Liu Jiang had to work around the clock.Shooting on TV during the day and dubbing part-time at night, there is almost no time to sleep.But like other actors, Liu Jiang never complained."It’s hard, but I also feel lucky. As long as you are willing to do it, you will have something to do without sleeping."



Today, 76-year-old Liu Jiang is still active in the front line. In 2020, he was nominated for the best supporting actor with the Golden Jubilee Building.


For him, acting is a "play addiction"."When I play the role, that kind of enjoyment will make me smile when I look back.""People think I’m crazy, but it’s this feeling, like being addicted, that has kept me doing it for decades."



The above mentioned ones are just the epitome of countless "licorice actors" hidden behind the characters.They are willing to be green leaves and achieve their roles, but they often get a meager salary, and it is difficult to make a living by acting alone.


I once lamented in an interview that licorice actors are always the one who is ignored on the set, and the last scene that stays up all night is often left to the oldest actors, which is unfair.



In traditional Chinese medicine, "licorice" is mostly a drug introduction, not the protagonist, but it is indispensable.


The same is true of "licorice actors". They have no superstar in front of the curtain and no star aura behind the scenes, but they really shape every role with their heart.


So, please try to remember their names. These licorice actors who play seriously and live hard deserve more respect from the industry and us.


Young artists trapped in the "suicide curse" in Korean entertainment circle have died one after another.

CCTV News:Recently, there was another bad news in the Korean entertainment circle. The 27-year-old Korean male artist Che Renhe was found dead at home. This is the third young Korean artist who died suddenly in just over a month. The first two were women and both committed suicide. Tragedy happens frequently, and people can’t help sighing. What happened to the Han Yu circle? Some people even say that the Korean entertainment circle seems to be caught in a "suicide curse".

On December 3, South Korean actor Che Renhe was found dead at home.

Che Renhe, 27 years old, debuted in July 2017, when he was a member of the actor group Surprise U, and later appeared in many online dramas and hit TV series.

Cherenhe usually gives the impression that he is an optimistic big boy. The day before his death, he posted on social media Instagram, urging fans to take care of themselves in the cold winter.

This made fans feel very confused about the death of Che Renhe.

At present, the police are investigating the cause of Cherenhe’s death.

In just 50 days, this is the third time that the Korean entertainment circle has heard the death of a young artist.

On October 14th, Sulli, an artist of SM, a famous Korean entertainment company, was found dead at home at the age of 25. At present, the police speculate that his death was due to suicide.

The agent said that Shirley suffered from severe depression before her death.

After Sulli’s death, Koo Hara, her good friend and idol artist, broadcast live on social media and wept bitterly:Shirley,My sister is in Japan,I can’t see you off, I’m sorry!When you get there,I hope everything will be as you wish,Sister will work hard to live together for you.

However, Koo Hara finally "reneged".

On November 24th, one month and ten days after Shirley’s death, 28-year-old Koo Hara was found dead at home.

Like Shirley, Koo Hara, who debuted as a women’s group at the age of 17, is well-known in South Korea.

She sang, appeared in TV series and participated in variety shows, but she also suffered from depression because of various pressures.

It is speculated that Sulli’s death may be the last straw to crush Koo Hara.

Young artists with beautiful youth and bright future have died one after another, which makes people have to re-examine the Korean entertainment circle.

"45 degrees out of the way" screen traffic police to dispel doubts: pressing the solid line will not deduct points.

  Chloe Wang cartography

  The traffic police directed the vehicle to make way for the fire engine behind him.

  In the past two days, the "45-degree way" has suddenly been screened on major social platforms, and many people have defined it as "the necessary skills for driving in 2020".

  In an animated simulation video, a three-lane road is congested, and there is an ambulance behind it that sounds the alarm and needs to urgently transport the patient forward. In order to let the ambulance pass through the congested road section as soon as possible, all vehicles turned sideways at a 45-degree angle to their left and right, which made a narrow "life passage" for the ambulance.

  Is it really feasible to brush the screen with a 45-degree way? What if I press it to the solid line? The reporter learned from the traffic police and the fire and emergency departments that this law is not only feasible, but also has been staged in Hangzhou more than once.

  Is it feasible to give way at 45 degrees? The traffic police said: feasible

  Will it be deducted if it is pressed to the solid line? The traffic police said: No.

  The relevant person in charge of the traffic police department said that everyone is obliged to give way when they drive on the road and encounter an alarm from an emergency vehicle (such as an ambulance, a fire truck, a police car, etc.) performing a task behind them. At present, there is no authoritative statement on how to give way, and drivers can operate according to the actual situation. "For example, on an elevated or expressway, if there is a road queue congestion and there is an emergency vehicle in the rear, everyone should try to lean to the sides and give way in the middle while ensuring safety ‘ Life channel ’ Come. "

  Therefore, the "45-degree way" is feasible in theory, but in practice, all vehicles need to cooperate with Qi Xin. "There are not only cars on the road, but also large trucks and buses with different lengths. In addition, if the vehicles are not well coordinated or the driver’s own operation is wrong, other scraping accidents may occur during the road."

  A driver asked: "If you press into a solid line or run a red light because you make way for an emergency vehicle, will you be deducted?"

  The traffic police said: In an emergency, life is the priority. "If you make way for emergency vehicles such as ambulances, fire engines and police cars in the case of congestion on expressways and elevated roads, you will not be penalized if you can prove it."

  In the morning rush hour, the fire alarm was blocked.

  The traffic police directed the private car to stage a textbook concession.

  In Hangzhou, a textbook-level "45 degrees out of the way" was recently staged.

  It happened on the 23rd of last month, when the squadron of Yuhang Town, Hangzhou received the dispatch — — On the east-west avenue of Yuhang Street, a spontaneous combustion accident of a new energy electric vehicle occurred on the roadside less than Wen ‘er West Road. After receiving the alarm, Yuhang Town Squadron dispatched two cars and 14 people to the scene for disposal.

  It was the morning rush hour, and the road leading to the scene of the incident was very congested. Especially in places less than 500 meters away from the scene of the incident, the traffic volume was so great that the fire truck could not travel smoothly. Looking at the black smoke from the scene not far away, the firefighters on the fire truck were extremely anxious.

  Just then, some vehicles in the traffic began to lean on both sides of the road to make way for the fire truck. A traffic policeman also arrived in time to direct the vehicles to move to both sides to clear the road for the fire truck. With the cooperation of the traffic police command and the on-site car drivers, the fire truck finally arrived at the scene smoothly and put out the fire in time.

  In order to get praise from drivers, the fire department urged drivers and friends, such as Lu Yu fire engines, ambulances, police cars and other special vehicles that are performing emergency tasks, to let them go first and make way for their lives on the premise of ensuring safety.

  Ambulance driver:

  The front of the front car is biased, and the rear car will follow the example of Qi Xin and work together to make way for life.

  After a night of tossing, at 8 o’clock yesterday morning, 46-year-old Shen Huigang finally got off work with a tired body.

  He is the driver of the first-aid point of the First People’s Hospital of Hangzhou. His main job at ordinary times is to drive an ambulance, and he will assist the doctor when he meets a critical patient. He has been driving here since the first aid point was set up in 2009. Previously, he had driven a bus and worked as a car attendant … … In short, he has dealt with all kinds of cars. When he applied that year, he was the only Vivi who stood out from more than 300 people.

  Master Shen’s night shift is from 6 pm the previous day to 8 am the next day. Last night and this morning, he drove seven times, which was a small number, and there were more than 10 times when there were many. On the Internet, Master Shen also noticed the "45-degree giving way method". As a witness, Master Shen is still very emotional — —

  "To tell the truth, there is still a big difference between driving an ambulance and other cars. When encountering critically ill patients, the requirements for our drivers are fast and stable, and we have to have a map in our hearts, including many small streets and alleys, just to save time and cost. " Master Shen said.

  As for the "45-degree way", Master Shen thought it was completely operable, and he also encountered it. "At 50 meters in front of the ambulance, a car heard the sound, and the front of the car was biased, which was not so accurate as 45 degrees, but it was done. The next few cars will follow suit, and we can pass more smoothly. This requires the concerted efforts of all of us, Qi Xin, and we all have such awareness. To be honest, cars that grab the driveway also exist, and we are very helpless. " Master Shen said that the Zhonghe Elevated Road and Times Elevated Road, which they often pass, are the most prone to congestion. As long as they are not blocked and can pass slowly, they can operate the 45-degree way.

  Driving on the road, Master Shen personally felt the change — — In recent years, everyone’s quality has gradually improved. When they see an ambulance, more and more drivers take the initiative to give way. "For example, on the viaduct, many cars will slow down when they hear the ambulance. Our vehicles can also take the middle lane, and there are many such news in the media. I think that no matter who sees an ambulance or hears its sound, they should have a sense of giving way, and pull over or stop. We are transporting emergency patients. After all, it is a life channel to save people! "

  Article 53 of the Road Traffic Safety Law:

  Police cars, fire engines, ambulances and engineering rescue vehicles can use alarms and sign lamps when performing emergency tasks; On the premise of ensuring safety, other vehicles and pedestrians should give way without being restricted by driving route, driving direction, driving speed and traffic lights.

  Paragraph 3 of Article 21 of the Procedures for Handling Illegal Acts of Road Traffic Safety:

  If there is evidence in the illegal behavior information recorded by traffic technology monitoring equipment or entered into the road traffic illegal information management system that it is caused by rescue or emergency avoidance, it shall be eliminated. If the penalty notice is finally received, the owner can appeal to the traffic police department, which will give priority to verification and write it off at the first time.

Animation: Beyond Entertainment and Accompanying Growth

  Guangming Daily reporter Yang Sa

  Animation is an important part of most people’s childhood memory and growth.

  Cartoons are a way for some parents to "kill time" for their children.

  Cartoons will inadvertently shape children’s value orientation and behavior, and the importance of children’s growth is self-evident. This "June 1st", let’s talk about how to make children watch cartoons better and see better cartoons — —

  Recently, Jiangsu Consumer Protection Committee (hereinafter referred to as "Consumer Protection Committee") conducted a survey on the consumption safety of minors in the animation field, and found that 1,465 problems were sorted out in the 21 cartoons surveyed, mainly focusing on terms, scenes, plots and so on. For a time, it caused a heated discussion among netizens. Some people think that some cartoons do have a lot of content that is not suitable for children to watch, and it is urgent to find out. Others think that cartoons have little influence on children and should not be made a fuss.

  Why do cartoons have these "problems"? According to Song Lei, director of the development research department of China Animation Group, the so-called "young" cartoons for children are the most difficult to do. "It needs to be supported by a strong theoretical basis of chromatics, acoustics and psychology, and our domestic ‘ Younger children ’ Many cartoons are written by writers simply according to their own preferences, and the directors simply shoot according to their own ideas, so there will be various inappropriate languages, actions and plots investigated. "

  1. The plot is green and healthy, which can cultivate aesthetic sentiment and see the world with imaginative eyes — —

  Children’s cartoons should meet three levels of needs.

  When his son was four or five years old, He Li (a pseudonym) found that he especially loved watching fighting cartoons, and usually used toys to imitate the scenes in cartoons. Referring to the impact of these fighting scenes on her son, He Li is "not very worried". She is more worried that the simple setting of cartoons will make her son "stupid". "Many cartoons have presuppositions, assuming that the world should be like this, but it is not. There are many possibilities in the world. And this kind of cartoons are all the same routine, and I feel that my cognition of children is not very good. " He Li said.

  Zhong Xiaolin, an associate professor at the School of Primary Education of Capital Normal University, often watches cartoons with children in kindergarten. In her view, cartoons are related to aesthetic education, moral education, and education of life experience and common sense. Zhong Xiaolin is very concerned about the sense of lines in cartoons. "For example, in the 1960s, Shanghai Fine Arts Studio’s" Make a scene in Heaven ",its overall color matching is very particular, and the lines of characters are also very soft, all with radian lines, which are very aesthetic. If some characters in cartoons have sharp lines, the message that may be conveyed to children is not so harmonious. "

  "Moral education in cartoons not only refers to the value orientation of the overall content, but also is reflected in the speech acts of animated characters in many cases. For children before the age of 5, black and white characters are more conducive to their acceptance. What is wrong is wrong, and what is good is good. If the role is designed to be too complicated and vague, it is not conducive to children of this age to distinguish right from wrong. " Zhong Xiaolin said.

  However, Zhong Xiaolin also said that sometimes it is difficult to judge that an animation is bad from individual bad pictures. "Maybe there is a plot in which a child bullies another child. What is important is what kind of influence this behavior has brought to the bullying child. If children who bully others find that they have no friends, they can educate children who watch cartoons and let them know that bullying has bad consequences. However, if there is no positive value guidance after bullying, such cartoons are definitely not good. "

  Different parents will pay attention to the different characteristics of cartoons. How can it be regarded as cartoons suitable for children? In this regard, Song Lei pointed out that children’s cartoons should meet three requirements: "The first level is safety. The plot should be green and healthy, the action should not have imaginary violence elements that can be easily imitated, the sound should not be big and small, and the light color should not flash too fast. The second level is beauty. This kind of beauty should meet the psychological needs of children, and it has aesthetic feeling in character design, prop design, scene design, sound design and so on, which can cultivate children’s aesthetic sentiment. The third level is creativity. Animation is an art of imagination, which should be fully creative in plot structure and world outlook structure. Look at the world with imaginative eyes. The screenwriter of children’s animation needs to make the plot develop beyond expectations but reasonably from the perspective that children can accept. I heard many primary school students complain that some cartoons are too ‘ Naive ’ Yes. This kind of ‘ Naive ’ In fact, there is no creativity and no imagination. "

  2. Social cognition can’t keep up, creative consciousness can’t keep up, and grading won’t have a good implementation effect — —

  The animation grading system needs to be gradual.

  In the investigation of Jiangsu Consumer Protection Committee, 828 parents, accounting for 80.7%, asked whether the screening scale of cartoons in the market needed to be further strictly controlled. For the introduction of the animation grading system, 562 parents expressed great support, accounting for 54.8%; 389 parents expressed their support, accounting for 37.9%.

  Animation grading system refers to the classification of different audiences of animation works according to their age groups, and stipulates the corresponding broadcast range, broadcast time and audience for different levels of animation works.

  In order to allow people of all ages to watch suitable cartoons, there was also public opinion that the cartoon grading system should be adopted. At the National People’s Congress in 2018, Wang Jiajuan, a deputy to the National People’s Congress and a teacher of Liaoyang No.1 High School in Liaoning Province, pointed out that in order to attract more people of all ages to watch, some cartoons were mixed with some violence and vulgarity, but they could attract high-age audiences. She called for the implementation of a grading system for domestic cartoons, so that children can learn real knowledge in the process of watching cartoons, develop a correct outlook on life and values, and give children a happy and healthy good work, not just satisfying temporary entertainment.

  In this regard, Zhong Xiaolin believes that cartoons need to have a bottom line, and those that violate socialist core values, laws and basic family ethics must not be included. If the cartoons are graded, the objects should also be considered. For example, the cartoons watched by children of different ages, such as preschool, lower primary school and middle and high primary school, should also be differentiated. From the content, value guidance, music, picture color and other aspects, we need to have certain indicators to measure.

  "It is an international practice to implement hierarchical management of cultural content products, which is the general trend in the long run. Establishing a grading system will not only help us to protect children in the domestic cultural market, but also help our products to connect with the international market and make children’s animation works that are more in line with international needs and can go overseas. " Song Lei said.

  However, Song Lei maintains a cautious attitude towards the grading system. "The establishment of a grading system will not happen overnight. First, its policy cost is relatively large. The upgrading of hardware and software related to classification and the popularization of knowledge all require huge investment. Second, its implementation effect depends on the overall level of China audience’s cultural quality. Parents call for grading, but a few parents really know what grading is and how many grades it is divided into. How to guide children to recognize grading? From the enterprise level, do you understand the characteristics of works of different levels and have the ability to create works of various levels? I’m afraid it’s difficult. It is very likely that the government has promoted it, but the social cognition can’t keep up, and the awareness of creation can’t keep up, so it won’t have a good implementation effect. "

  In the absence of grading system, how to ensure that cartoons can have a positive impact on children? "The grading system should be gradual. First, popularize the knowledge of classification and classification, encourage and guide enterprises to create classified works without classification, and the audience will watch them in classification. When the overall social cognition reaches the requirements of the grading system, the creative ability of enterprises reaches the level required for grading, and then it is fully rolled out, perhaps the effect will be better. " Song Lei thinks, first of all, we should work hard on the theme. Create more works on the themes of Chinese excellent traditional culture, revolutionary culture and advanced socialist culture, and subtly sort out the cultural identity and cultural self-confidence of children by the theme content. Secondly, we should consciously implant the value orientation. Let children experience truth, goodness and beauty by watching animation. Finally, let the animated characters play the role of behavior demonstration. Children can easily imitate the language and actions of characters in animation, so we should give full play to the behavior demonstration function of animated characters. Sometimes, if animated characters say two more words of "thank you" and "sorry", it may make children develop the habit of being polite to others. On the contrary, if animated characters have impure language and rude behavior, it is easy for children to be adversely affected.

  3. The "hands-off education" of "shaking the phone" can make parents save effort, but it cannot guarantee the efficiency of children’s information reception — —

  Parents need to deal with the relationship between customs control and children’s independent choice.

  "Under what circumstances will children be allowed to watch cartoons?" According to the survey results given by Jiangsu Consumer Protection Committee, more than half (50.9%) parents checked the rewards for their children who have other things to attend to and spare time after school, and 45.6% parents allowed them to distract their children when they were noisy. This kind of "mobile phone-throwing" "hands-off education" undoubtedly saves parents energy, but it cannot guarantee the efficiency of children’s information reception.

  This phenomenon has also been confirmed by Zhong Xiaolin. She found that in most families, if cartoons are used as a family learning method, it is a spontaneous, observation-based and infiltration learning method. "So this kind of daily learning method basically fails to see parents’ purposeful and conscious educational design. In the playful learning, the child is in the stage of relaxation, and absorbs the information conveyed by cartoons with the interest accumulated slowly in his own life. "

  What Zhong Xiaolin doesn’t quite agree with is that parents make too many purposeful, planned and lead-in designs and settings for their children to watch cartoons. "Cartoons can be used as children’s free time, positioning cartoons in the family’s entertainment life, and children can also learn during such entertainment time." Zhong Xiaolin said. "And as children learn and grow from infancy to primary school, they will gradually form their own appreciation. From this perspective, children should have more autonomy in what kind of cartoons they watch."

  "But what parents really need to do is to check the periphery of cartoons." Zhong Xiaolin believes that in the scene where parents and children watch cartoons, it is better to take a more compromise approach. It is necessary to respect the children’s choices and give positive guidance. What Zhong Xiaolin often takes is to watch with the children. For example, the characters in cartoons have violent words and behaviors, and Zhong Xiaolin will patiently say to the children, "Is this yelling very noisy? Is it uncomfortable to listen?" That means this behavior is wrong. " "Fade the bad influence to children in time" is what Zhong Xiaolin called "participatory intervention".

  "Parents need to deal with the relationship between the control and the children’s independent choice, and properly guide the children so that they can re-recognize and re-learn the behavior scenes presented in cartoons. This is how the most natural family education happens. " Zhong Xiaolin said.
