How much does the express "invisible face sheet" attract attention to protect personal information?

  The main reasons for the frequent disclosure of personal information in the express delivery industry are that a few express delivery companies are not strict in internal control and do not pay attention to the protection of personal information. Paying attention to the protection of personal information means increasing investment, which means cost, and increasing cost means decreasing income. On the other hand, buying and selling information can also make money, which leads to the disclosure of personal information becoming the norm.

  The current laws, including the Consumer Protection Law and the Cyber Security Law, all mention the protection of personal information. The key is to enhance the operability, litigation and arbitrability of the law for the protection of personal information.

  In order to better protect users’ personal information, YTO Express, a courier company, recently launched an "invisible face sheet".

  In this regard, Weibo, the official of the State Post Bureau, announced that YTO Express implemented an "invisible face sheet", which did not show all the information of name, mobile phone number and address, but only part of it.

  To what extent can the "invisible face sheet" protect personal information? In this regard, the "Legal Daily" reporter interviewed industry experts.

  The meaning of "invisible face sheet" may be limited

  Once the "invisible face sheet" was launched, it immediately attracted the attention of all walks of life.

  According to Tan Shuhua, senior director of YTO Express R&D Center, at present, the "invisible face sheet" mainly has three "hidden functions", which can encrypt the user’s mobile phone number, name and address. For example, for the user’s mobile phone number, some numbers will be hidden by technical means.

  The official Weibo of the State Post Bureau also published photos about the "Invisible Face Sheet".

  How much can the "invisible face sheet" play in protecting personal information?

  "For the protection of personal information, ‘ Invisible face sheet ’ It can still have a big effect. There are mainly two aspects. First, the courier can’t see all the personal mobile phone numbers and other personal information of consumers. Second, people who receive express delivery instead of consumers, such as property and security guards, can’t see the personal information of consumers. Of course, ‘ Invisible face sheet ’ Certainly not foolproof. " Liu Junhai, vice president of China Consumers Association and a professor at Renmin University of China Law School, said.

  “‘ Invisible face sheet ’ Can play a role, because ‘ Invisible face sheet ’ Encrypted by technical means, it is impossible for individual courier brothers to sell express orders and collect personal information. In other words, it is becoming more and more difficult for couriers to buy and sell personal information directly. " Lawyer Qiu Baochang, a member of the Expert Committee of the China Consumers Association, said.

  “‘ Invisible face sheet ’ It is already available abroad, but the amount of application is not large, mainly used for some items involving special value and special privacy. " Xu Yong, chief consultant of Express Logistics Consulting Network, said that the "invisible face sheet" is actually a two-dimensional code technology, which needs to be scanned before you can see the relevant information of the recipient.

  Judging from the published photos, YTO Express’s "Invisible Face Sheet" belongs to bar code.

  Xu Yong believes that bar codes belong to one-dimensional codes. The QR code has more information. The "invisible face sheet" can be a two-dimensional code or a one-dimensional code. One-dimensional code may be used to save costs, and sorting is not affected. If two-dimensional code is used, scanning equipment needs to be replaced.

  "There are many links in express delivery. As far as the traditional express delivery industry is concerned, express delivery is directly received by couriers, which involves personal information, which is an unavoidable problem in the traditional express delivery industry. It is also worth considering how personal information works well in the background of the courier company and how to properly protect it. " Qiu Baochang said.

  “‘ Invisible face sheet ’ Its role in protecting personal information is limited. Because from the perspective of personal information disclosure, it is too expensive to collect personal information through express delivery sheets. From the perspective of buying and selling personal information, it makes sense to buy thousands of pieces of personal information. For the problem of personal information disclosure in the express delivery industry, everyone should still treat it rationally. The courier list belongs to a single personal information and has limited value. " Xu Yong said, "‘ Invisible face sheet ’ The real significance is that it shows that our express delivery enterprises are becoming more and more mature and have a stronger sense of service, and can provide personalized services. I think ‘ Invisible face sheet ’ The significance of this aspect is greater than that of personal information protection. "

  Employee training and education is the key.

  News about the disclosure of personal information in the express delivery industry has been exposed in the media from time to time.

  After the Xu Yuyu case, some media reported that "after the express waybill passed through many links, such as e-commerce, consignee, sorting and entry, many times personal information had already been leaked and sold on the Internet".

  "The main reason why the express delivery industry has repeatedly leaked personal information is that a few express delivery companies are not strict in internal control and do not pay attention to the protection of personal information. Paying attention to the protection of personal information means increasing investment, which means cost, and increasing cost means decreasing income. On the other hand, buying and selling information can also make money, which leads to the disclosure of personal information becoming the norm. " Liu Junhai said.

  Xu Yong believes that there are mainly the following channels for express delivery to disclose personal information: one is that "hackers" attack to steal personal information. In the Internet age, it has become a new illegal and criminal channel to make profits by using network loopholes and illegal operations, which is characterized by a large amount of illegal access to personal information. For example, a large express delivery company was exposed to 13 information system security vulnerabilities, and "hackers" used this to steal more than 30,000 customer information. The characteristic of this channel for obtaining customer information is that it needs technical means, and it obtains the most personal information of customers, which is difficult for ordinary people to do. Another channel is duty crimes committed by couriers and related personnel. In order to obtain illegitimate interests, some couriers and related personnel use their positions to sell customers’ personal information to so-called "buyers". The characteristic of this channel for obtaining customer information is that it is generally done by employees, and the amount of personal information obtained by them varies. The third channel is that e-commerce related personnel sell customer information. The personal information of customers held by e-commerce is consistent with the information of express waybill, and express delivery is the downstream of e-commerce. In order to increase personal income, some e-commerce workers resell customer information to their peers or through the Internet to obtain illegitimate income.

  "There are also online bulk purchases or sales of customer personal information to earn the difference. The price of each courier information varies from a few cents to several yuan according to the quantity and classification. Most buyers and sellers complete transactions through the Internet, and the buyer’s transaction volume is tens of thousands or even tens of thousands. Some websites can also meet special needs such as designated receiving and delivery locations. To expand ‘ Business scale ’ Personal information wholesalers are also recruiting agents all over the country. This channel for obtaining customer information is characterized by the largest amount of customer personal information and the most profit. " Xu Yong said.

  Weibo, the official of the State Post Bureau, also mentioned that companies such as SF Express and Suning had introduced similar measures through data desensitization technology. Through scientific and technological means, express delivery companies are carrying out more and more humanized, safe and informative service practices, which can effectively protect consumers’ personal privacy.

  While express delivery companies are upgrading their technical means to protect personal information, industry experts generally believe that it is essential to strengthen employee education.

  "Express companies should strengthen the education of employees. Sometimes express employees disclose personal information because they don’t know the law, ignorant people are fearless, and the cost of violating the law is not high. When employees join the company, it is necessary to make it clear that personal privacy must be respected and protected. It is also necessary to increase penalties for employees who violate regulations. " Liu Junhai said.

  "Overall, the use of technical means by express delivery companies is more effective in protecting personal information. The focus of employee education and training is to abide by laws and regulations. If the legitimate rights and interests of consumers are harmed, there should be some penalties. Let employees know the relevant laws and regulations, not to disclose and buy or sell personal information. If such behavior occurs, in addition to punishment, it should be publicized. We know that the courier brothers are very hard now. However, the courier company can still take a little time every week to train them in laws and regulations. " Qiu Baochang said.

  According to Xu Yong, as early as June 2015, "Three Links and One Reach"+SF Express entrusted Bee Network to develop the express logistics credit information system, and 30 kinds of express delivery personnel (even if they resigned) including leaking customer information have been included in the query system for untrustworthy personnel. The information in the "blacklist" of the express logistics credit information system will be kept for five years; The "blacklist" has been opened for free to express logistics credit cooperative enterprises. There are nearly 400 free open query interfaces. In the recruitment of these express delivery companies, thousands of "blacklisted" personnel were refused to be recruited through inquiry and comparison, so that these "blacklisted" personnel could not work again in the express logistics industry.

  Enhance the operability of the law

  As an important part of e-commerce, the express delivery industry is also becoming an important part of personal information protection.

  According to media reports, the e-commerce law (draft) reviewed at the end of last year clearly defined the responsible subjects such as e-commerce platform, merchants, payment and express delivery in several chapters. According to the draft, the maximum penalty for failing to fulfill the obligation of personal information protection is a fine of 500,000 yuan, and it is ordered to suspend business for rectification until the business license is revoked. If the case constitutes a crime, criminal responsibility shall be investigated.

  Xu Yong believes that although it is clearly stipulated in the Postal Law that postal enterprises and their employees are not allowed to disclose user information, otherwise, enterprises will be confiscated of their illegal income, fined between 10,000 yuan and 50,000 yuan, and may be ordered to suspend business for rectification or even revoke their business licenses; The illegal income of the relevant personnel will also be confiscated and a fine ranging from 5,000 yuan to 10,000 yuan will be imposed. If the circumstances are serious, it will be handed over to the public security organ for criminal responsibility. The criminal law also stipulates that the collection and reselling of personal information shall be investigated for criminal responsibility according to the circumstances. However, in the actual supervision, express delivery companies are faced with difficulties in finding, investigating, obtaining evidence and punishing, that is, stealing customer personal information is more difficult to find than stealing express mail, which is very concealed.

  "In the e-commerce law, it is necessary to further write down the relevant clauses realistically. The current laws, including the Consumer Protection Law and the Cyber Security Law, all mention the protection of personal information. The key is to enhance the operability, litigation and arbitrability of the law for the protection of personal information. " Liu Junhai said that the relevant departments can also consider establishing a "red list" system, so that those enterprises that respect consumers’ privacy rights can get more opportunities to develop and enjoy certain convenience in financing, rating and procurement.

  "From a legal point of view, it is necessary to strengthen the legal responsibility of the express delivery industry, and also enhance traceability and operability. Now a key problem is that the source of personal information leakage is not easy to find out. Personal information disclosure involves many industries, not just the express delivery industry. How to effectively combine tracing and punishment, I think this should be considered in law. " Qiu Baochang said.

Starting from 126,900 yuan, Chery Tiggo 8 double cars joined the "championship" competition.

In 2023, both the new energy market and the fuel vehicle market have entered a state of fierce competition. The major car companies are crazy about the price and allocation of vehicles, and the reason is also to make the market share up. Among them, BYD has brought the champion model with lower price, which has indeed added a lot of help to its sales. Now Chery’s champion model has arrived as scheduled.

A few days ago, Chery Automobile announced that the Tiggo 8 PRO Champion Edition and PHEV Champion Edition models were officially launched. The price range of the Tiggo 8 PRO Champion Edition was 126,900-163,900 yuan, and the price range of the Tiggo 8 New Energy Champion Edition was 137,900-159,900 yuan.

In terms of car purchase benefits, Chery has also brought you a six-fold car purchase gift, including paying 1,000 yuan to 10,000 yuan in cash-filled red envelopes, enjoying a replacement subsidy of 15,000 yuan at the highest level, a lifetime warranty for the whole vehicle, a financial discount of 7,000 yuan, and a lifetime free basic flow, etc., which is full of sincerity.

Both cars are sincere.

In terms of appearance, the new car focuses on adding time gray body color, and adjusts the shape of the new car’s air intake grille, providing a fiercer air intake grille, a shiny Chery Logo and decorative strips. In addition, the new car also provides larger body wheels, such as 18-inch and 19-inch wheels and different styles, which greatly improves the visual effect. In terms of body size, the length, width and height of the new car are 4745/1860/1745mm and the wheelbase is 2710mm respectively.

The interior and configuration are basically the same, and the interior is the same as the cash. It adopts a three-spoke flat-bottomed steering wheel, equipped with a 12.3-inch curved double screen, and adopts the Lion car system. A large number of metal decorative pieces are used in the interior, which further enhances the luxury of the interior.

Among them, the Tiggo 8 PRO Champion Edition has added a black and light brown color scheme. As a medium-sized SUV, it also provides a seven-seat layout that can be used in an emergency. The new car has also introduced the well-received Queen’s co-pilot seat, but it has changed greatly in terms of the car. It has been replaced with a more mainstream Qualcomm Snapdragon 8155 chip, which can realize the functions of video playback with 4K resolution, 3D navigation, panoramic images and so on, and supports 5G network and V2X car networking technology.

In addition, the Tiggo 8 PRO Champion Edition also provides a series of comfort configurations and intelligent configurations such as 540-degree reversing image, electric heating of exterior rearview mirror, driving recorder, inductive tailgate, front seat heating, lane keeping, reversing side warning, HUD head-up display and so on.

Among them, the 1.6T turbocharged engine has a maximum power of 145kW and a maximum torque of 290 N m; The maximum power and torque of 2.0T engine are 187kW and 390 N m respectively. The transmission system is matched with a 7-speed dual-clutch gearbox, and the high-equipped models will also be equipped with a four-wheel drive system.

Tiggo 8 New Energy Champion Edition is equipped with the power combination of 1.5T super-efficient engine and dual motors for hybrid power. The comprehensive power of the system is 240kW, and the comprehensive torque is 545N.m It only takes 7.2 seconds to accelerate 100 km, and at the same time, it realizes super power output in full speed range, 2 seconds for 0-30km, 3.1 seconds for 30-70km and 3.8 seconds for 60-100km.

Tiggo 8 New Energy Champion Edition is equipped with a hybrid special 3-speed DHT electric hybrid system and a hybrid special ternary lithium battery, which can achieve a comprehensive battery life of 1000km+. At the same time, the car is also a "fuel-saving weapon", and the minimum fuel consumption under WLTC working condition is 5.95L/100km, which fits the user’s pursuit of fuel economy to the maximum extent. Moreover, the Tiggo 8 New Energy Champion Edition supports fast/slow charging, and the 220V power supply can be charged at will. It takes only 25 minutes to charge the power from 30% to 80%, making it more convenient for users to travel long distances.

Can you break the championship battle?

Since the beginning of the year, China auto market is experiencing an unprecedented price storm, which has spread to every corner of fuel vehicles and new energy sources. It is this storm that broke the traditional product pattern and consumption concept in the past. If Tesla’s official demotion at the beginning of the year was the first shot to start this year’s price war, then BYD Qin PLUS DM-i Champion Edition was the most powerful response of its own brand, and one after another "Champion Edition" models that followed it completely brought the story to a climax.

Especially in BYD Song plus, a market segment, it has become the king. It not only beat down the price of cooperative brand SUVs, but also made independent brand SUVs follow suit crazily, and launched brand-new products to compete with it, such as Geely’s Galaxy L7, Harvard’s Xiaolong and other new energy products, which made the competition in this market segment more intense. Now the sales of the latter two have steadily increased, which is enough to show that the market is very inclusive as long as the product strength and price are appropriate.

In addition to the Tiggo 8 PRO Champion Edition with high cost performance, the Tiggo 8 New Energy Champion Edition has launched a 55km leading edition, a 100km glory edition and a 100km king edition to meet the diversified car needs of users. At the same time, with the price range of 130,000-150,000 yuan and the Tiggo 8 New Energy Champion Edition, it achieved "the same price of oil and electricity" and entered the increasingly competitive mixed market, becoming the best solution in the minds of potential users.

Since its launch, Chery Tiggo 8 series has won the market and reputation with its excellent product strength and high cost performance. It sold 20,440 new cars in July, and the cumulative sales from January to July this year reached 117,799. Now Chery has brought a lower-priced champion model on the basis of the high product strength of the Tiggo 8, and there is also a new energy champion version of the Tiggo 8 with the same price of oil and electricity. I believe that in the future, it will also seize and occupy a place in the increasingly "involuted" mixed market, so that more users can have more suitable and higher-value new choices, and at the same time, the sales of the Tiggo 8 series will be further improved.

When the body control system has a sense of autonomy, a comprehensive analysis of BYD Yunqi

ChatGPT was born, which triggered a global hot discussion and thinking. In just a few weeks, people both lamented the rapid development of artificial intelligence and were shocked by the great changes brought by new technologies to life and production, as if suddenly, computers really had self-awareness.

Artificial intelligence, as a substitute for human labor force, is only the tip of the iceberg. What kind of changes can be imagined when ChatGPT is applied to the automobile field? At present, technology has developed to pre-process the influence of each terrain and road condition on the car body, so as to adjust the suspension in advance to improve comfort, handling and safety, but most of them are limited to high-end models of luxury brands and have not been systematically popularized. However, with the release of BYD Yunqi Intelligent Body Control System on April 10th, this situation will be completely changed. From passive suspension to active suspension to intelligent body control, the awareness of body is awakening.

First, create the highest level of global body control system. 

BYD Yunqi System is the industry’s first exclusive intelligent body control system for new energy. The full name of Yunqi is Yunqi intelligent adaptive body control system, which is an intelligent body control system developed by BYD for five years and costing billions of dollars. Including Yunqi -C intelligent damping body control system, Yunqi -A intelligent air body control system, Yunqi -P intelligent hydraulic body control system and unlimited Yunqi -X control system.

Yunqi represents the highest level of the global body control system, which brings subversive improvement to new energy vehicles of BYD Auto’s brands, covering different use scenarios such as home, sports, administration and off-road, and creating an all-round and luxurious driving experience for users. When the new energy vehicle has no traditional engine and gearbox, the impact of chassis technology on the driving experience of the whole vehicle will be further amplified, so the brand of electric vehicle has higher and higher requirements for chassis and suspension. Independent research and development is costly and time-consuming, and it is usually unbearable for brands with poor product matrix, which leads most car companies to choose outsourcing chassis technology, which is easily affected by technical bottlenecks and soaring costs.

Second, from perception to decision-making to implementation, break the monopoly of foreign car companies in one fell swoop.

Electrification has brought about the transformation of the whole vehicle architecture, and the vehicle control has changed from mechanical control to electrical signal control, and the accuracy, efficiency and intelligence have been greatly improved. The body control system, which integrates software and hardware technologies such as perception, decision-making, control and interaction, can not only surpass the past, but also provide rich car scenes. This is the intelligent body control system of Yunqi, and the following three levels are the core of Yunqi technology.

Perception is the premise of cloud chariot.

The first key problem of Yunqi is road perception technology, which is the first step to realize intelligent body control. The preview system deeply integrates multiple road surface sensing elements such as monocular/binocular cameras and laser radar to identify road surface features and elevation curves within the range of 5-150m in front of the vehicle, and the recognition accuracy is as high as 3 mm, and the recognition accuracy is over 99% within 15m. It not only realizes the functions of road surface recognition and all-terrain monitoring, but also can quickly adjust and adapt with the suspension system.

Accurate decision-making is the key to Yunqi.

After mastering the core technologies such as software architecture, strategy formulation, algorithm design, etc., BYD’s self-developed Yunqi Intelligent Computing Center has multi-core and efficient processing capability, supports multi-signal interfaces, and can drive various actuators. Through cloud computing, it can process information such as road state, body posture and wheel load, and output the best control strategy in real time.

Take high-speed cornering as an example. Usually, the center of gravity of the vehicle will tilt to the inside of the corner, thus reducing the comfort and handling performance. Yunbi can automatically adjust the suspension located inside the corner, reduce the movement frequency by increasing damping, and achieve the purpose of hardening the suspension. From the completion of road preview, to intelligent decision-making and implementation, Yunqi Supercomputing Center has realized highly centralized integrated control.

Efficient execution is the guarantee of Yunqi.

For the implementation level of Yunqi, BYD independently developed and controlled the whole process through structural design, performance simulation, test methods and other aspects, and combined with the full-stack self-research of system software, it can achieve the perfect adaptation effect of suspension software and hardware. Yunqi intelligent adaptive body control system achieves millisecond response adjustment from the state identification of sensing parts, to the information processing decision of Yunqi Supercomputing Center, and then to the control execution of the whole vehicle.

In addition, users can also control the suspension height and damping mode through the voice control or manual adjustment interface at the APP end of the mobile phone and the Pad end of the vehicle, thus gaining more fun.

Third, "devolve" luxury and make "value" upward.

Next, we interpret Yunqi -C, Yunqi -A and Yunqi -P respectively to see what contribution they have made to chassis awareness.

Yunnian -C intelligent damping body control system-popularization of technology, entering the homes of ordinary people.

Yunqi -C is the first active suspension product in China to realize full-stack self-research in system design, calculation, modeling, simulation, matching and adjustment. The system architecture includes key components such as perception component, decision component and execution component. The suspension system of Yunqi -C can actively control the electronically controlled shock absorber according to the road condition information, and the damping can be adjusted steplessly, which mainly serves the comfort and sports modes.

When the vehicle passes through the bumpy road, the comfort control strategy of high frequency and small damping is adopted to make the chassis "soft", which can effectively buffer the road excitation input and quickly restrain the vertical movement of the car body. Under the condition of 60km/h continuous vibration road surface, Yunqi -C can help the whole vehicle achieve 96% vibration isolation rate, which greatly improves the comfort compared with the traditional suspension. The roll speed of 100km/h double lane can also be reduced by 39.7%.

Yunqi -C is mainly used to improve daily driving comfort and handling performance, such as body pitch, corner roll and steering angle at medium and high speed, etc. This is a popular version of product matrix. At present, more than 80,000 vehicles have been loaded on BYD Han EV, Tang and Tengshi D9, and the product experience has been well received by the market. Later, it was officially upgraded to Yunqi -C through OTA software.

Yunnian -A Intelligent Air Body Control System-Breaking the monopoly, luxury and comfort are no longer far away. 

Yunqi -A intelligent air body control system is the first suspension product in the world to realize full-stack self-research in system design and calculation, simulation selection, function and strategy development, software algorithm development and integration, matching and adjustment technology and key parts design. The system architecture includes sensing, decision-making, execution components, and key components such as adjustment part. Its biggest highlight lies in the high integration of three adaptive adjustments of suspension height, spring stiffness and damping hardness with the adaptive adjustment function of dynamic embracing seat, which is of pioneering significance in the industry.

The total lifting stroke of Yunqi -A can reach up to 150mm, which can restrain the acceleration of the car body and brake pitching by more than 25%, and provide two modes of manual and automatic adjustment. In addition, the suspension height is adjusted adaptively with the change of vehicle speed.

BYD also creatively integrated the self-adaptive adjustment function of the dynamic embracing seat into Yunnian-A. In order to suppress the inertia deviation caused by the roll of the vehicle when cornering at high speed, the dynamic embracing seat provides airbag support at the waist of the seat, so that the user can maintain a good driving posture and ensure the safety and comfort of high-speed driving. According to the news of the press conference, Yunnian -A will be the first to ride on Tengshi N7.

Yunnian -P intelligent hydraulic body control system-the world’s first new energy, providing a strong off-road gas field.

Yunqi -P is the world’s first new energy exclusive intelligent hydraulic body control system developed by BYD. It efficiently integrates three core subsystems, namely mechanical, hydraulic and electronic control. The system architecture includes sensing components, decision-making components and more complex execution components. It has the functions of one-button leveling, single-wheel lifting, four-wheel linkage, simultaneous adjustment of height, stiffness and damping. The working environment covers -40℃ to 85℃, with an altitude of 6000m, which is suitable for extreme and harsh environments such as high temperature, cold, high humidity and high corrosion.

The biggest difference between Yunqi -C and Yunqi -A is that Yunqi -P can stably bear the sprung load weighing up to 5 tons. It is an intelligent hydraulic body control system with the maximum load-bearing capacity for new energy passenger cars among the active suspension products released in the industry. In addition, Yunqi -P has a wide range of suspension height active adjustment and four-wheel linkage capabilities. The total adjustment stroke of the front suspension and the rear suspension is 200 mm. When facing off-road scenes such as bullet holes and cross shafts, all four wheels can touch the ground as much as possible to provide sufficient tire grip and balance. And when camping on uneven ground, the four-wheel suspension can be lifted independently to keep the car body level.

As BYD’s first million-class luxury car, I hope U8 will not only surpass the predecessors of traditional SUVs, but also bring the safety, comfort and intelligence of intelligent chassis, and also bring the luxurious and comfortable feeling of integrating technology, new energy and new platform, covering all kinds of car scenes such as transportation, off-road, leisure and business.

To sum up, three different intelligent car body control systems actually correspond to three different consumption and car use scenarios, and the significance of cost performance and popularization brought by Cloud -C; Yunqi -A Active Road Perception and Advanced Air Suspension: Yunqi -P’s cross-era off-road innovation makes users feel the significance of intelligent body awakening from different levels of high school, middle school and low school.

Fourth, the autonomy of production equipment to software and hardware is the core of cloud technology.

From the perspective of global automotive technology, in addition to Rolls-Royce, there are three intelligent body control systems familiar to domestic consumers, namely, the magic body control system applied by Mercedes-Benz in GLE, the magic carpet intelligent air suspension of BMW 7 Series and Audi A8L active suspension technology.

BYD’s cloud technology not only fills the last short board on the traditional chassis, but also combines the pre-control with the wire-controlled chassis, creating a new integrated technology of vertical integration and realizing the straight-line overtaking of traditional car companies and new forces.

The core components of Yunqi released by BYD this time, such as compressors, distribution valves, testing instruments and so on, are all developed and produced by BYD, and the product matrix is subdivided into Yunpan -C, Yunqi -A and Yunqi -P, which comprehensively covers all civilian use scenarios to correspond to different models and consumer demands respectively. This chess game can be said to make opponents dream of it.

Five, R&D investment broke 20 billion, BYD technology is king.

Although the active body control system is not new, the whole technology of Yunqi is self-developed by BYD, which not only gets rid of the dependence of domestic brands on parts suppliers, but also realizes the independence of core technologies, which is the most admirable place. Especially when this system is endowed with perception layer and decision-making layer, the "self-awakening" suspension will bring us unprecedented experience and fun.

In order to increase its core competitiveness, BYD has made great efforts in technical input and output in recent years. In 2022, the accumulated R&D investment was 20.223 billion yuan, up 90.31% year-on-year. By the end of 2022, BYD had applied for more than 39,000 patents and authorized more than 28,000 patents worldwide, with nearly 70,000 R&D personnel. Under the research and development and investment at any cost, the peak technologies such as blade battery, DM-i super hybrid, E platform 3.0, CTB battery body integration and "Easy Sifang" have been released one after another, and the emergence of Yunqi has enabled BYD to keep ahead in technology, and at the same time, it has provided consumers with the best choice, no longer subject to the serious premium of joint ventures or imported cars, and truly fulfilled the significance of technology changing their lives.

The arrival of "snow and ice fever" Ski beginners must collect this Raiders →

Chongli, Hebei Province has received more than 420,000 tourists since it started skiing on November 8, and Altay, Xinjiang has received more than 2 million tourists since mid-October.

Since the winter, people’s enthusiasm for ice and snow has continued to rise. However, skiing also requires doing your homework in advance. For example, how to choose a suitable ski resort? What are the precautions when choosing equipment? What are the safety knowledge and skills of skiing? How to deal with unexpected situations and injuries? Next, we will answer your questions one by one.

one

Skiing enthusiasts gather and it is important to choose the right ski resort.

As the venue of the snow events in Beijing Winter Olympics, Chongli in Zhangjiakou has just successfully held the alpine skiing points competition of the International Snow Federation. In this snow season, nearly 30 high-level snow events at home and abroad will be held here, including the International Snow Federation U-venue World Cup, the 14th National Winter Games platform skiing and nordic combined. Excellent snow quality and high-end events have attracted skiers from all over the country to worship. How to choose the right snow field? The relevant person in charge of Chongli Sports Management Department said that the state and local governments have unified standards for the hardware level of ski resorts.

Xia Zeyu, Director of Winter Sports Management Center of Sports Bureau of Chongli District, Zhangjiakou: In Chongli, for example, the thickness of our snow rolling must be greater than 30 cm. There needs to be a protective net around each snow trail to prevent some out-of-control tourists from rushing out of the snow trail and play a role in protecting tourists. This snow trail must be flat, without those debris, and it must be flat at the end area.

In addition, the choice of ski resort depends on whether the protective facilities and rescue facilities are complete. A compliant ski resort needs to be equipped with relevant cable car facilities, and at the same time, professionals are needed at the location where the cable car gets on and off to ensure the safety of skiers. In addition, in the emergency facilities, in addition to the normal emergency rescue equipment, snowmobiles, snow patrol personnel and rescuers should be equipped, so that skiers can get timely rescue and treatment when they are injured.

Choose appropriate ski equipment protection to ensure safety.

Skiing requires speed, passion and protection. For beginners, how to choose the right ski equipment?

The reporter at the reception desk believes that with the arrival of the snow season, more and more skiers join the ski army. How to make everyone ski safely, let’s learn from the choice of ski equipment and ski trails.

Ma Guolong, coach of a ski resort in Altay City: It is very important to choose a snowshoe that suits you, and the size should be suitable. The size of the snowboard is long or short. Generally, we say that the snowboard can reach our chin. Generally speaking, our elbows are bent at 90 degrees, and the tip of the stick just falls to the ground. Next, choose a helmet, and then snow goggles. The ultraviolet rays are relatively strong in sunny days, so we can choose the reducing mirror to prevent tanning and sunburn, and it also has a certain protective and windproof effect when the sliding speed is relatively fast. In addition to the reducing mirror, there are also intensifying mirrors, which are generally suitable for skating at night, and are also used in cloudy days.

In addition, professional ski suits that are breathable, warm and elastic should generally be selected, and it is best to have the effect of keeping warm and drying quickly. There will be subtle differences between single board and double board in the choice of ski equipment. Generally speaking, you should choose the ski equipment that suits you.

Master safety knowledge and skills and enjoy skiing.

After wearing ski equipment, you need to correctly choose the ski trail and master the basic safety knowledge and skills of skiing.

According to reports, snow trails are generally divided into primary, intermediate and advanced snow trails according to different slopes. After the ski equipment is ready, you can choose your own ski trail according to your own level. In the process of skiing, it is necessary to avoid skiing outside the snow trail. For beginners, there are several "basic skills" that need to be mastered before going on the snow trail.

Wu Peng, Vice President of Altay Ice and Snow Association: The basic posture of skiing is that the body should lean forward slightly, the calf should press the tongue of snowshoes, and the center of gravity must not be backward. There is also a skill to master before going on the snowy road, that is, how to wrestle. When you are out of control and about to fall, throw away your poles, put your arms around your shoulders, bend, and naturally go sideways. You can’t fall back and forth, but fall left and right.

Avoid "secondary injuries" in case of skiing accidents.

High-speed sports have their own risk points, so does skiing. How to minimize accidents in skiing? What should I do after an accident? Come and listen to the opinions of professional coaches and rescuers.

Sun Wenhao is a ski instructor and a second-level referee of snowboarding. Sun Wenhao, who has been teaching for 8 years, has encountered many incidents in which skiers fell or collided with each other and were injured.

Sun Wenhao, a ski instructor in Chongli District, Zhangjiakou: Many beginners will choose to sit in the same place after falling, which is a wrong behavior. After the fall, we should move to the side of the snowy road in time to adjust. There is a blind spot in skiing, and you should also observe the rear more when skiing.

If skiers are injured on the snowy road, they should call for rescue at the first time and wait for rescuers to arrive for transshipment.

Zhang Yuefan, captain of the patrol team of a ski resort in Chongli District, Zhangjiakou: If you are slightly injured, you can move to the edge of the snowy road and rest in the same place. Call the rescue number on the snowy road and wait for rescue. If you fall to the caudal vertebra or lumbar vertebra and move yourself, it may cause secondary injury. Try not to move on the snowy road, call other snow friends, call for help and wait for rescue.

five

Warm up before skiing and don’t blindly increase the difficulty.

Expert advice: Before skiing, you should make full warm-up preparations and don’t blindly increase the difficulty.

Experts say that some skiers often cause many accidents during the exercise because they don’t prepare for the warm-up beforehand.

Zheng Ya ‘an, vice president of Chongli Campus of Peking University Third Hospital: Doing high-speed or high-risk sliding exercise often leads to muscle strain, joint sprain and ligament contusion. Physical recovery training, especially the stretching of joints and ligaments, should be carried out before skiing. It is suggested that skiers choose their own trails according to their physical conditions, and don’t blindly overweight themselves too early to increase the difficulty, speed and height.
