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.

Xiaomi car first exposure! Is it exciting to open books at a low price？

Author | Li Yan Source | Brand Front Page

Some time ago, Lei Jun’s annual speech was screened on the Internet.

Some netizens found that in the three-hour discussion about brand growth and cognitive breakthrough, Lei Jun didn’t say anything about building a car, which suddenly triggered various speculations.

Just a few days ago, it was revealed that Xiaomi had been successfully approved by the planning department and had the qualification to produce electric vehicles.

What followed was the photo that Lei Jun recently posted on the social platform. The banner read "Fight for Xiaomi Car!"

Laman expectation

On August 23, some media reported that Xiaomi had been successfully approved by the planning department and had the qualification to produce electric vehicles.

This indicates that,Xiaomi Auto is one step closer to the goal of mass production early next year.

Xiaomi has also become the fourth company approved to build a car since the end of 2017.

It is reported that if a company wants to enter the field of new energy vehicles, it needs to obtain "double qualifications" to meet production and sales. The acquisition of double qualifications is extremely difficult.

This is one of the reasons why Weilai, Tucki and other new car-making forces choose OEM.

As can be seen from other media reports, Xiaomi has investment layouts in five major areas: intelligent driving, intelligent cockpit, intelligent network connection, intelligent electric power and car cloud service.

As the industrial chain matures, Xiaomi Automobile will be officially on the road soon.

In fact, Lei Jun basked out."Fight for Xiaomi Automobile"At the time of the banner, some netizens posted spy photos of Xiaomi cars galloping on the highway in Xinjiang.

At the same time, Hu Zhengnan, a partner of Shunwei Capital Investment, also exposed the energy consumption performance of Xiaomi Automobile during Lei Jun’s release of a series of Weibo trends located in Xinjiang.

Under normal circumstances, a medium and large car, such as Tucki P7, Tesla Model S and other single-motor models, whose energy consumption per 100 kilometers is less than 15kWh is an excellent level.

The Xiaomi car under test has an energy consumption data of 8.8kWh, which is far lower than the current average of 15.8, and it can be regarded as excellent performance.

As soon as this data came out, it directly filled the expectations of rice noodles.

It is reported that,Xiaomi plans to produce about 100 thousand electric vehicles next year. At the same time, it is confirmed that the battery suppliers at this stage are Zhongchuang Singapore Airlines and Contemporary Amperex Technology Co., Limited.

As the attention continues to rise, the design of Xiaomi car’s configuration, laser radar, frameless door and closed grille exposed by bloggers in May this year is even more eye-catching …

Mass production is imminent

As early as Xiaomi Investor Day in October 2021, Lei Jun said that Xiaomi Automobile is expected to be officially mass-produced in the first half of 2024.

In the past three years, news about Xiaomi automobile has emerged from time to time. News such as the completion of the first phase of the factory and the purchase of spare parts confirmed the steady progress of Xiaomi’s car.

At present, there seems to be more and more "breaking news" about Xiaomi Automobile.

According to media reports, the photos of Xiaomi’s new car road test show that the first model will be a coupe with a slip-back design.

The seemingly long front of the car is slightly different from the inherent impression of netizens on pure electric vehicles. At the same time, the new car is expected to have a closed front end design to further optimize aerodynamic performance.

In addition, although the car body is covered with "camouflage", it can still be seen that lidar equipment is mounted on the top of the car.

Some netizens boldly gave an "irresponsible" guess through the details of the pictures-at least there are two versions with and without lidar.

The first one is that the roof is equipped with a laser radar, and the wheel hub adopts a hollow Y-shaped hollow shape, as well as a "high-equipped" version of the yellow brake caliper.

The other is that there is no lidar on the roof, and the hub shape is more focused on reducing air resistance than the previous hollow design.

Of course, in addition to configuration, netizens are more concerned about the pricing of Xiaomi Automobile.

After all, Xiaomi can quickly occupy the minds of young consumers by maximizing the cost-effectiveness advantage.

In June of this year, Xiaomi’s intelligent AI assistant "Little Love Classmate" made an own goal of "Xiaomi Car Pricing" when answering questions from users.

The head of public relations of Xiaomi Group denied rumors in Weibo: "Xiaomi Auto will be released next year, so how can there be a price now? Xiao Ai’s reply was to grab a report on speculation in 2022. "

However,According to the price of "online transmission", the high-end version may cost 299,000 yuan, and the low-end version is 199,000 yuan..

Xiaomi insiders said that the price will be adjusted according to the market situation next year, and this price may not be the final pricing.

If this price is true, it seems to be a little far from "the first electric car for young people".

What we prefer to believe is that Mr. Lei has "persuaded the board of directors overnight".The overall profit margin of Xiaomi’s hardware will not exceed 1%.. As for the profit point, it depends on software services and ecosystem.

In those days, Lei Jun beat down the price of mobile phones by "overnight persuasion", and consumers used high-priced products with real prices.

Therefore, the profit rate of "persuading executives overnight" will not exceed 1%, which makes netizens have the expectation that "good things are about to happen".

Intellectual priority

In fact, in the new energy track, the profit margin of no more than 1% is basically a beautiful imagination.

For any car company, it needs to rely on huge scale effect to achieve it.

The "small profits but quick turnover" often mentioned in the consumer market, if you want to maintain the daily expenses of car companies, I am afraid it is a bit difficult to even "plug your teeth".

Take BYD, the industry’s "profit extreme", as an example.

Some investment banks have done rough calculations. The cost price of BYD’s 2023 Qin Plus DM-i is 99,000 yuan, while the starting price of this model is 99,800 yuan.

This also means that selling a BYD may only earn a few hundred yuan, and the profit rate is even less than 1%.

▲ Source: BYD Weibo

From the data point of view, its net interest rate in the first quarter of 2023 was only 3.64%, even lower than the 7.15% of Toyota, a traditional fuel vehicle company.

As a new energy head brand, this is still the case. It just means,At present, the "model" of hardware comprehensive profit rate in the automobile market is less than 1%, which is really a beautiful imagination..

However, BYD has perfect upstream and downstream industries, and many factors are affecting the profit margin of the brand.

For BYD, the premise of "small profits but quick turnover" is the efforts of cost control such as upstream and downstream connection and mass production, as well as the revenue support of multiple explosions at the same time.

For Xiaomi Automobile, the advantage lies in the sound volume of Xiaomi brand and the cognitive label of "cost performance".

The existence of these stickers made Xiaomi, which sold 33.2 million mobile phones in the second quarter of 2023, still attractive in the eyes of consumers.

Nowadays, the automobile market has reached its peak. Whether Xiaomi Automobile can once again come up with a cost-effective "killer" to conquer consumers is another matter.

Some netizens believe that the new energy track may only be low enough to subvert the industry.

In my opinion,Sufficient low price is based on cost control, showing the leading edge of intelligent driving, chips, power batteries and other fields..

Since the new energy track was opened, the price is not the only consideration for consumers to buy, but the better product "intelligence" and user experience are.

In March, 2021, when Lei Jun officially announced that Xiaomi was building a car, he said: "I am willing to put all my reputation in life and personally lead the team to fight for Xiaomi Automobile."

When the mass production of Xiaomi car is just around the corner, will this dream of building a car with Lei Jun’s reputation in life conquer more young people?

We will wait and see.

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. "

The national six b emission standards will be fully implemented, and what changes will the automobile industry welcome？

　　Xinhua News Agency, Beijing, May 23rd　Question: the national six b emission standards will be fully implemented, and what changes will the automobile industry welcome?

　　Xinhua News Agency reporters Zhang Xinxin, Yan Fujing, Gao Kang

　　The Ministry of Ecology and Environment, the Ministry of Industry and Information Technology and other departments recently jointly issued an announcement. From July 1, 2023, the national sixth emission standard 6b stage will be fully implemented, and it is forbidden to produce, import and sell cars that do not meet the national sixth emission standard 6b stage.

　　The "boots" of the emission standard policy have been put on the ground, accelerating the automobile industry to enter a new stage of green development. What changes will the full implementation of National Six B bring to the automobile market? Will the fuel vehicle market usher in a "price reduction tide"? Will it accelerate the promotion of new energy vehicles?

　　The car market share of "National Sixth B" exceeds 90%, and the industry has entered a new stage.

　　"National Six Standards" is a standard for preventing and controlling motor vehicle pollution emissions and improving ambient air quality. The "National Six Standards" for light vehicles set two emission limit schemes, National Six A and National Six B, which were implemented in 2020 and 2023 respectively.

　　National Sixth B is about to be fully implemented, but the preparation of the market and industry is not limited to the present.

　　"Since ‘ National Six Standard ’ Since its release, most enterprises have directly carried out product research and development and production in accordance with the requirements of the National Six B standard. The industry is equivalent to implementing the National Six B standard in advance, and the National Six B vehicles occupy a major market share. " The relevant person in charge of China Automobile Industry Association said that many models have already completed the transformation of National Six B, and there is no technical difficulty from the perspective of enterprise production. It is understood that since the implementation of the standard, the proportion of light-duty vehicles in the national six B vehicles has exceeded 95%, and the market share of the national six B vehicles has exceeded 90%.

　　Guangzhou Automobile Group said that all its fuel vehicles have been switched to the National Six B standard; Changan Automobile also shows that there is no pressure for the arrival of National Sixth B, and the newly launched Yida is in line with the National Sixth B standard … … Facing the implementation of standards, manufacturers are ready.

　　The reporter interviewed a number of industry experts and said that from the perspective of the new car market, the implementation of the National Sixth B will not have much impact on the auto market. The National Sixth B Standard has been promoted in advance in first-tier cities such as Beijing and Shanghai, and the implementation of the new regulations has little impact on the automobile market in these cities. In other cities that haven’t implemented the national six-B standard, if there are relatively many vehicles in stock in the national six-A, there will be a certain price drop in the short term, but this will be experienced in all previous emission standard switches. The development trend of green and low carbon in automobile industry itself is the embodiment of market demand, which will also accelerate the transformation of automobile enterprises and industries.

　　Half-year sales transition period, to promote the smooth continuation of the market.

　　The release of the national six emission standards has given the market a long adjustment window. Implementing standards in advance in key areas is conducive to alleviating the industry pressure when the policy is formally implemented.

　　At the same time, the announcement made it clear that for some light-duty vehicle models such as National Six B, which were reported as "monitoring only" in the actual driving pollutant emission test (RDE test), a half-year sales transition period was given and sales were allowed until December 31, 2023. This move is also to enable manufacturers and distributors to rationally plan the layout and complete the product switching and sales as soon as possible.

　　The reporter learned from China Automobile Industry Association that China Automobile Association has established an inventory scheduling mechanism with the top ten automobile groups and other member units to organize and schedule industry inventory data on a monthly basis. By the end of January 2023, there were more than 1.89 million vehicles in stock that did not meet RDE requirements.

　　The person in charge of China Automobile Industry Association believes that the current inventory pressure is caused by objective factors. Among them, there are some factors such as "demand contraction, supply shock, expected weakening" and other factors such as the poor performance of the automobile market, and it takes some time for product production to switch, and new energy vehicles accelerate the replacement of traditional fuel vehicles. After months of promotion, the inventory has fallen sharply.

　　"The policy gives a half-year sales transition period, which is conducive to stabilizing the mentality of dealers and enterprises, orderly destocking, and helping the car market to make a smooth transition." Cui Dongshu, secretary general of the National Passenger Car Market Information Association, said.

　　Accelerate the guidance of green intelligence and promote industrial iterative upgrading.

　　The industry believes that the full implementation of the national six B emission standards has a positive role in promoting the iterative upgrading of the fuel vehicle market and the new energy vehicle market.

　　Recently, the the State Council executive meeting deployed to speed up the construction of charging infrastructure. The National Development and Reform Commission and the National Energy Administration issued the "Implementation Opinions on Accelerating the Construction of Charging Infrastructure to Better Support the Rural and Rural Revitalization of New Energy Vehicles". A series of policies to encourage automobile consumption, especially to support the consumption of new energy vehicles, have been introduced to accelerate the upgrading of the industry to green and intelligent.

　　With industrial orientation and policy support, car companies have accelerated their layout, and the market is constantly exploring model innovation: Chery recently announced preferential measures for going to the countryside, and its "QQ Ice Cream" went to the countryside to launch 1000 yuan/Taiwan car purchase subsidies; Charging service providers can promote the penetration of business in rural areas, forming a charging service network covering 55,000 stations and 575,000 charging guns nationwide; Hangzhou Longyuan Electric Power Co., Ltd. and related units jointly worked out the optimal power supply scheme of charging station, and monitored the working state of charging pile and charging protection system in real time through digital technology & HELIP; …

　　The proportion of freight new energy vehicles is constantly increasing, and the market promotion of new energy vehicles is accelerated. Take Lala as an example. In October last year, the proportion of new energy truck drivers on the platform reached 25%. According to the prospectus of Cargo Lala, by the end of last year, Cargo Lala had over 35,000 electric vehicle charging stations in over 270 cities in China.

　　"Industrial upgrading is the general trend." Xu Haidong, deputy chief engineer of China Automobile Industry Association, believes that both the implementation of emission standards and the promotion of consumption policies will further promote the green transformation of the entire automobile industry and accelerate the popularization and application of new energy vehicles. The next step is to do a good job in policy implementation and continuously improve the overall competitiveness and development quality of the automobile industry.

Domestic flights of most domestic airlines will completely resume hot food supply.

China Eastern Airlines passengers ate hot meals.

　　With the gradual improvement of the domestic epidemic situation, the civil aviation industry has ushered in a rapid recovery. Beijing Youth Daily reporter learned from China Eastern Airlines that China Eastern Airlines resumed the supply of hot meals on domestic flights except Xinjiang and Dalian on August 16th.

　　In July, passengers of China Southern Airlines, Hainan Airlines and other airlines have enjoyed steaming meals.

　　In August, with China Eastern Airlines, Air China and Shenzhen Airlines resuming hot meals on domestic flights in batches, by mid-August, domestic flights of most domestic airlines will completely resume hot food supply.

　　China Eastern Airlines launched more than 500 kinds of aviation meals.

　　Since August, China Eastern Airlines’ domestic flight volume has exceeded 2,400 flights per day, which has returned to more than 95% of the normal level, and simultaneously launched "Fly with Your Heart 2.0" & mdash; — "Fly at will in the morning and evening" aviation products. Faced with the rapid recovery of the civil aviation market, according to the relevant requirements for the prevention and control of normalized epidemic situation in various places, China Eastern Airlines began to resume hot meals on domestic flights in an orderly manner in August. From business boutique routes in Beijing, Shanghai and other places to routes in most parts of the country, China Eastern Airlines launched more than 500 kinds of aviation meals for passengers to taste.

　　In the newly launched "Cloud Food", first-class and business-class passengers will not only taste the "China Eastern Airlines Bowl of Noodles" again, but also taste local specialties such as Longjing Shrimp, Rib Rice Cake and Crab Powder Lion Head.

　　The "Mother’s Taste" series of meals in economy class will also return, and passengers will be able to taste the home-cooked flavors such as pickled pork noodles, fried tofu pork rice and bacon rice again.

　　In addition to dinner, the "Yicai Edainty" series of fine dim sum meals will continue to be served on board. Mung bean cakes, Swiss rolls, energy tarts and other dim sum will be packaged in Chinese style, and will be presented in "hand-held" boxes or paper bags that are convenient to carry according to different shipping spaces.

　　China Eastern Airlines provides meals for domestic flights over 91 minutes.

　　In the process of making meals, China Eastern Airlines has taken a number of measures to manage production personnel and food raw materials on the basis of the original food safety control system, further strengthening the control of food hygiene. In the process of meal production, we not only do a good job in health examination and temperature measurement of employees in strict accordance with epidemic prevention requirements, but also suspend the purchase and use of imported frozen seafood raw materials, and use beef, pork and other related meal dishes to improve the taste of meals while ensuring the safety and hygiene quality of meals.

　　It is reported that after the full recovery of hot meals on August 16, China Eastern Airlines will provide hot meals for all cabin passengers during the morning, noon and evening dinner hours for domestic flights with actual flight time exceeding 91 minutes; In addition, the business class of Xiamen-Shanghai and Changsha-Shanghai routes will also serve hot meals before 8: 30 pm. China Eastern Airlines also practices "CD Action" together with passengers and says "no" to "food waste" through measures such as fine catering, providing more delicious and exquisite meals and verbal tips from flight attendants.

　　Earlier, since August 1st, China Eastern Airlines has resumed hot food supply in all round-trip flights on 12 domestic business boutique lines (Shanghai-Beijing/Guangzhou/Shenzhen/Chengdu/Kunming/Chongqing/Xi ‘an, Beijing-Guangzhou/Shenzhen/Chengdu/Chongqing/Xi ‘an).

Do you remember these little common sense of life when the cold wave strikes？

　　CCTV News:

　　Cold wave strikes, high-risk groups should be alert to cardiovascular and cerebrovascular diseases.

　　With the sudden drop of temperature, cardiovascular and cerebrovascular diseases will also enter a period of high incidence, and the elderly and patients with chronic diseases such as hypertension and diabetes need to be vigilant.

　　Low temperature is easy to cause diseases such as myocardial infarction and cerebral infarction.

　　Cold weather can lead to vasoconstriction, stimulate blood pressure to rise and heart rate to accelerate, and easily induce angina pectoris, myocardial infarction, cerebral infarction and other diseases. People with high risk factors such as the elderly, obese people and smokers, and people with chronic diseases such as hypertension, hyperlipidemia and diabetes should be more vigilant. Drugs for lowering blood pressure, blood lipid and blood sugar cannot be stopped without authorization; In the event of sudden increase in blood pressure, chest tightness, chest pain and other uncomfortable symptoms, you should see a doctor in time.

　　Ma Changsheng, director of anzhen hospital Cardiology Medical Center and Arrhythmia Center:We say that angina pectoris is not necessarily painful, for example, boredom and suffocation are angina pectoris. Or if our chest is depressed and painful for 10 minutes or even more than ten minutes at rest, it means that his coronary heart disease is serious.

　　Acute cardiovascular and cerebrovascular diseases should be treated as soon as possible.

　　Experts stressed that for acute cardiovascular and cerebrovascular diseases, time is life, and the earlier treatment after onset, the better.

　　Ma Changsheng, director of anzhen hospital Cardiology Medical Center and Arrhythmia Center, said: "The most important time for acute myocardial infarction is prime time. The sooner, the better, and the best is within 60 minutes. For the public, you should know that you should act as soon as possible, call 120 or drive at home and go to the emergency department of the hospital as soon as possible. Within 60 minutes, we (the hospital) will open the patient’s blood vessels. "

　　What parts should you pay attention to when you travel outdoors to keep warm?

　　Experts suggest that outdoor activities should be avoided as much as possible during the cold wave. If you have to go out, you should pay attention to cold and warmth. Usually people wear thick down jackets and warm shoes when they go out, but one part is often overlooked, and that is the head. Because of the dense blood vessels, the head is very sensitive to the cold and the body is warm, but the exposure of the head to the cold wind will also cause blood vessels to contract. A warm hat and a mask that is worn regularly are not only conducive to epidemic prevention and control, but also can effectively resist the cold wave.　

　　"Drinking can keep out the cold" is a misunderstanding.

　　Young people should pay attention to the cold wave, regardless of age. Some young people don’t wear long pants or expose their ankles even in winter, which experts think is not advisable, and there is a risk of cardiovascular and cerebrovascular diseases. "Drinking can keep out the cold" is also a misunderstanding. After alcohol enters the human body, it will cause blood pressure to drop, blood vessels to dilate and blood circulation to accelerate, but at the same time it will also accelerate heat dissipation, and the body temperature will become lower and lower. When blood pressure drops, it will also lead to an increase in heart burden. Going out after drinking alcohol in cold weather is likely to have serious consequences.

　　Cold wave strikes, walking in rain and snow to prevent falling.

　　Cold wave strikes "wrestling" in rainy and snowy days is learned.

　　The road is slippery on snowy days, because sudden diseases such as fractures caused by wrestling also occur from time to time. In particular, osteoporosis in the elderly, walking on ice and snow roads, a little carelessness may lead to fractures. So, when wrestling is inevitable, will you "fall"?　

　　Most of the fractures after snow are concentrated in the wrist, ankle and waist.

　　Clinically, fractures after snow are mostly concentrated in the wrist, ankle and waist. When slipping, many people will subconsciously hold their hands on the ground. Because of the great instantaneous force when they touch the ground, it may be transmitted to the wrist and shoulder, resulting in wrist and shoulder joint fractures. If you can make a correct response when you fall, you can greatly reduce the chances of injuries such as fractures.

　　Sun Fenglong, director and chief physician of the Second Department of Orthopaedics, Beijing Rehabilitation Hospital affiliated to Capital Medical University:We can make an action as much as possible in the process of falling, with our hands protecting our heads and our forearms close to our chest, which is similar to this action. We can protect our important organs and avoid further injuries in the process of sliding forward or backward.

　　Don’t get up after falling to avoid secondary injury.

　　Don’t get up in a hurry after falling, so as to avoid secondary injury. To ensure safety, first feel the physical condition.

　　Sun Fenglong, director and chief physician of the Second Department of Orthopaedics, Beijing Rehabilitation Hospital affiliated to Capital Medical University:First of all, move the joints all over the body, including the important head, cervical vertebrae and joints of limbs, and move the waist. If there is severe pain, it means that there may be a serious fracture, or at least one part has a fracture. In this state, don’t try to stand up by yourself.

　　Rescuers should not blindly drag, pull, carry the injured. The correct way is to set up signs to warn passing people and vehicles, and at the same time call 120 emergency number to be rescued by professional medical staff. If you have to move the injured person, you should move the injured person as a whole and slowly, and don’t bend, twist or move the injured person greatly.
