It is reported that it will be OEM. On October 19, in response to the above rumors, BAIC Blue Valley responded that the company did not receive relevant information.

Beiqi Blue Valley rose 22.18% for three consecutive trading days in recent days. On the evening of October 18th, it was announced that the daily operation of the company had not changed significantly.

According to reports, informed sources revealed that Xiaomi had approached at the end of August this year to discuss matters related to OEM new energy vehicles, but the two sides failed to reach a final cooperation.

In addition, it is reported that Xiaomi has negotiated with Chery, Brilliance and other car companies, which may be responsible for production, while Xiaomi is responsible for sales, but the specific results are not yet known.

Xiaomi Automobile plans to build a vehicle factory in Yizhuang, Beijing in two phases. The first phase of the factory has been basically completed and put into use, with a production capacity of 150,000 vehicles per year. Lei Jun’s goal in 2024 is to sell 100,000 vehicles.

It is reported that after the first coupe model of Xiaomi Automobile, it plans to launch an SUV model, but it does not consider rebuilding the production line, so it turns to negotiate OEM production with other automobile manufacturers to achieve two-track advancement.

According to the plan, Xiaomi Automobile will be officially mass-produced in the first half of 2024, and it is getting closer and closer to the first half of 2024.

In terms of investment, the financial report shows that Xiaomi’s investment in innovative business such as smart electric vehicles in 2022 is RMB 3.1 billion. By the end of 2022, the size of the R&D team of automobile business was about 2,300 people.

Regarding the configuration and price of Xiaomi car, there have been many reports on the Internet, and even the road test data have been sent online. Insiders pointed out that the high-end version of Xiaomi Automobile is priced at 250,000 yuan to 300,000 yuan.

It seems that everything is ready for Xiaomi to build a car. However, regarding the qualification of building a car, there is no clear official news yet.

There are indications that Xiaomi Automobile is progressing smoothly and getting closer and closer to the press conference. However, at this time, Bloomberg gave rice noodles full of expectations.Spilled itA pot of cold water, they reported that Xiaomi has not got the qualification to build a car.

It is also reported that Xiaomi has obtained the production qualification of electric vehicles, but the official has not officially responded. The mass production of Xiaomi automobile may be unknown before it is officially qualified to build a car.

Since the official announcement of the car in March 2021, more than two years have passed, and Xiaomi has not let consumers see the real appearance of the car. The so-called official map that flowed out before always gave people the feeling of still hiding half her face from us behind her guitar.

So far, all kinds of news about the progress of Xiaomi Auto’s car-making have basically come from the network. The news seems to be a lot, but it is difficult to distinguish between true and false.

Say a few more words

According to Lei Jun, the goal of Xiaomi Automobile in the future is to strive to enter the top five in the world within 15 to 20 years, and Lei Jun also said before that to enter the top five, the annual sales may exceed 10 million.

Xiaomi, who is eager to catch up with the wind, is the only choice for Xiaomi, compared with Baidu, Huawei and other enterprises, and it is a little late to enter the game. However, Xiaomi’s research and development expenses are not too much in the entire automobile industry chain.

In fact, there is not much time left for Xiaomi automobile to enter the market, but if it is to form differentiated competitiveness in a short time, time is even more urgent.

Rumors about Xiaomi automobile are flying all over the sky.For this car company, the core asset is actually Lei Jun.To put it more directly, it is the credibility of Lei Jun.. After all, Xiaomi’s mobile phone has dominated the rivers and lakes for so many years, and Lei Jun’s credibility is still very high, which is much stronger than Jobs who still stays in the United States.

On December 28th, 2023, Beijing and Xiaomi held the Xiaomi Automobile Technology Conference, and the first model of Xiaomi Automobile "Xiaomi SU7" was displayed on the screen. Vision china diagram

Xiaomi car, which has not disclosed the official price, is still the focus of public opinion.

On January 8th, Lei Junfa Weibo, founder of Xiaomi Group, said that for Xiaomi Automobile, friends are concerned about many topics, and they will focus on answering the most typical 100 questions, which will be answered separately in three days.

"This time we just held an automotive technology conference, and the heat was so high that it exceeded our expectations. On the one hand, the huge heat represents the user’s expectation of Xiaomi car, and we are really happy. On the one hand, a large number of false information, rumors and malicious smears are also swarming. We will clarify in time, and we will resolutely pursue the legal responsibility of those who make rumors and smear. " Lei Jun said.

On December 28th, 2023, Xiaomi held the Xiaomi Automobile Technology Conference in Beijing, and Xiaomi SU7, the first product of Xiaomi Automobile, made its first public appearance. This model is positioned as a C-class high-performance coupe, and it is planned to be mass-produced in the first half of 2024. In addition, this conference officially revealed the breakthroughs in the five core technologies of Xiaomi Automobile, including key areas such as electric drive, battery, large die casting, intelligent driving and intelligent cockpit.

At the press conference, Xiaomi SU7 was almost spoiled, but the price remained mysterious, which became the focus of hot discussion.

For the price of Xiaomi car, Lei Jun once again stressed that it will not be 99,000, 149,000 or 199,000. The final pricing will be announced at the official press conference of Xiaomi SU7. "The prices of Xiaomi cars on the Internet are all false news, and we have not yet determined the final price."

There are also many netizens who are curious about whether the seemingly "expensive" Xiaomi SU7 will launch a low-end version, such as the "beggar-in-the-middle" version or the "Redmi version". In this regard, Lei Jun said that Xiaomi Automobile has a fully consistent product project criteria, and "experience priority" has always been put in the first place. Xiaomi SU7 is the standard version, and there is no plan to launch Redmi Automobile at present.

For the color of Xiaomi SU7 to be released in the future, Lei Jun revealed that more colors will be extrapolated beyond the disclosed Gulf Blue, Olive Green and Elegant Grey.

Previously, Lei Jun replied in the comments of netizens, "Is there an opponent within 500,000 (Xiaomi Automobile)?" In this question and answer session, Xiaomi reiterated that although this is a joke, it is also serious. "We are pragmatic and will not set those outrageous flag, so we are still very confident that Xiaomi SU7 has no rivals within 500,000 at present."

As for Lei Jun’s recent time allocation, Xiaomi responded in the Q&A that Lei Jun is still very concerned about the technology research and development of the mobile phone business. At this stage, his time and energy allocation is roughly as follows: at least 1/4 time is still spent on the mobile phone research and development business, 1/4 is concerned about the operation and management of the group, and 1/2 time is spent on the automobile business.

[The following is the full text of the question and answer]

1. A lot of rice noodle feedback. There are so many rumors about Xiaomi Automobile recently. Does Xiaomi Legal really have a job? When will the relevant progress be announced?

This time, we just held an automobile technology conference, and the heat was so high that it exceeded our expectations. On the one hand, the huge heat represents the user’s expectation of Xiaomi car, and we are really happy. On the one hand, a large number of false information, rumors and malicious smears have swarmed in, and we will clarify them in time, and we will resolutely pursue the legal responsibility of those who spread rumors and smears.

2. What is the pricing of Xiaomi Auto SU7? When will it be announced?

We really haven’t set a final price yet. Mr. Lei also introduced it at the Xiaomi Automobile Technology Conference. It is indeed a bit expensive, but it will be "expensive for a reason".

Not 99,000, not 149,000, not 199,000. The final pricing will be announced at the official launch conference of Xiaomi SU7.

3. There is a lot of news about the price of Xiaomi car on the Internet. Is it true?

The selling prices of Xiaomi cars are all false news, and we haven’t determined the final selling price yet.

The final selling price will be announced when Xiaomi Automobile is officially released.

4. Is the main content of Xiaomi SU7 basically finished?

On December 28th, 2023, the technical conference of Xiaomi Automobile was held. This time, we only introduced the five core technologies of intelligent electric vehicles, and the products are only a brief introduction. We still have a lot of technologies and product contents that have not been developed. I will introduce it to you in detail at the official conference of Xiaomi SU7.

5. Is the greater the pressure, the better? Why is Xiaomi die-casting 9100t?

What we often talk about here is the clamping force of large die casting. The determination of clamping force is designed by die casting. After millet integrated die casting, the floor is larger and more complex than Tesla Model Y, so the rated clamping force of 9100t is finally selected. In actual use, the maximum clamping force of millet under super high pressure is 9500t, and the stable value can reach 9300t t.

Clamping force is not the only index of large die casting technology. The properties of heat-free alloy raw materials, die-casting island cluster design, defect detection and so on are the core indexes to measure the large die-casting technology. Xiaomi is currently the only car company in the world and the only one in China with self-developed heat-free alloy materials and self-developed large die-casting island clusters.

6. Someone on the Internet said that Xiaomi’s big die casting was directly renamed from Haitian’s existing 8800t die casting machine. Is this true?

Of course not. Xiaomi Super Die-casting is 9100t (ton), which is not the model, but the actual rated clamping force. In fact, the clamping force of Xiaomi Super Die-casting Cluster in normal operation can reach 9500t. It is worth noting that Xiaomi’s super-large 9100t die casting machine was jointly developed by Xiaomi and Haitian. Based on the existing die casting machine technology, Xiaomi’s R&D team carried out 11 patent design innovations, most of which were invention patents, such as A I actively optimized the injection parameter setting system. But the die casting machine is only a link. Xiaomi has developed the whole die casting cluster system, including 60 equipments and 433 process parameters. For details, please click this link: Learn about Xiaomi Super Die-casting Cluster.

7. If it really hits a large die casting, how high is the maintenance cost of Xiaomi?

The tail of Xiaomi SU7 adopts a three-stage design, and the buffer zone is designed on the basis of the integrated large die-casting floor. Conventional collision only needs to replace the buffer collapse zone, and the maintenance cost is the same as that of the traditional design. When encountering extremely high-speed collision, the integrated large die-casting floor can provide better safety protection.

Generally speaking, the integrated floor design of Xiaomi SU7 after large die-casting is: the maintenance cost of small collision is not painful, and the big collision is stronger to protect your safety. It is the best solution at present.

8. Is the yield of millet die casting high? Will it bring quality problems if you use large die casting as soon as you come up?

Large die casting technology is a typical long-term technology, and it is also a ticket for future head car companies. From the very beginning, Xiaomi Automobile decided to research the whole stack and invest in two sets of die-casting island clusters at one time. In order to ensure foolproof, we also added a set of traditional stamping schemes at that time, and three schemes were done at the same time. Finally, the Xiaomi Super Die Casting Project landed smoothly.

At the same time, our self-developed technologies related to large die-casting island include temperature control system, aluminum liquid transfer system, injection system, pouring and drainage system, etc., and through our self-developed AI defect detection system, we can ensure the yield of millet SU7 integrated large die-casting floor.

9. What is the actual performance of Xiaomi Titan alloy? Is the self-developed alloy just to save costs?

Xiaomi Titan alloy is excellent in die-casting performance, mechanical properties, durability, recyclability, economy and so on. Xiaomi Titan alloy is also added with 40% recycled aluminum, which is very environmentally friendly. Xiaomi has become the only automobile manufacturer in China and the only one in the world with mass-produced self-developed large die-casting materials. As for why the alloy materials were developed by ourselves at that time, I also talked about it at the press conference. It was because the requirements of large die casting for alloy raw materials were extremely harsh. At that time, the supplier’s formula could not meet our requirements, so we had to develop the materials by ourselves. The cost of self-developed materials was definitely much higher than that of directly using mature schemes.

10. Is Xiaomi Titan alloy really self-developed?

Yes Some netizens may have been misled by the wrong information before. What everyone saw was the chat record of Professor Yang of a university. In fact, Professor Yang quickly clarified it. Praise for Professor Yang’s spirit of seeking truth from facts, and also regret the misunderstanding caused by it. I hope everyone can help me forward and clarify.

11. What’s the difference between the specific formula of Xiaomi Titan alloy?

Related patents have been publicly available, and the proportion of eleven elements used in the alloy has also been disclosed. (Patent number ZL 2023 1 0604165.9)

12. How much of the Xiaomi super motor series is self-developed?

We have officially released three types of motors, and at the same time disclosed a pre-research motor that has been experimentally realized. Among them, Xiaomi super motors V6 and V6s are jointly developed with UMC and Huichuan respectively, with a rotating speed of 21,000 rpm. At the same time, Xiaomi has developed the Xiaomi super motor V8s with a speed of 27,200 rpm, and this information has also been publicly disclosed by Huichuan on the interactive platform of A-share investors.

13. Is Xiaomi Motor V6 an old product of UMC? Why are the models and names the same?

Xiaomi motor V6 is a brand-new motor jointly developed by Xiaomi and UMC. Through the joint efforts of both parties, the stress topology structure of the motor rotor has been improved, and the speed and power density of the motor have been greatly improved, and relevant patents have been obtained.

The so-called "Xiaomi Motor V6 is an old model motor of UMC TZ220XS000 in 2020" is purely a rumor. TZ220XS000 is named only for national standard rules: TZ stands for permanent magnet synchronous motor; 220 represents the outer diameter of the motor; X represents a resolver position sensor; S stands for water cooling and heat dissipation; 000 is the brand code of UMC. The same internal name does not mean the same motor, which can be known from the publicly available information in the industry.

14. Is the V8s motor mass-produced?

The V8s has been mass-produced and will be put on the train in 2025. At present, some automobile evaluation media have measured the engineering vehicles loaded with V8s motors, and the measured V8s speed can reach more than 30,000 revolutions. However, the relevant test is the limit test, and the rated speed of V8s is still calibrated at 27,200 rpm.

15. How did Xiaomi’s super motor achieve a high speed of 35,000 rpm? Xiaomi was more powerful than Tesla for the first time.

Behind the high speed of 35000rpm, there are many innovative efforts in structural design, material technology and so on. Among them, the most important thing is that Xiaomi used "laser in-situ curing carbon fiber winding technology" to carry out innovative design of rotor sleeve of high-speed motor, and obtained relevant authorized rotor patents.

Compared with the wet winding method of carbon fiber, which requires brushing resin for curing after carbon fiber winding; In the laser in-situ curing winding process of millet, carbon fiber prepreg tape is used instead of carbon fiber precursor and resin glue, and the curing of carbon fiber prepreg tape is realized by laser while winding on the same station equipment. The process is simple, one station is completed, and the tension is directly maintained during the winding process.

16. Is CTB inverted battery really the first in the industry?

The battery core is inverted, which has happened in the industry; The pressure relief valve is inverted, which has happened before. However, the CTB battery cells which are inverted at the same time have never been inverted before. This technical solution pioneered by Xiaomi is to ensure the ultimate battery safety and the ultimate space utilization.

CTB is Cell to body, which is the design ability of automobile manufacturers. It is not only the technology of battery manufacturers, but also the integration of battery pack and body. The upper cover of battery pack is directly the floor of passenger compartment. Xiaomi has 36 core patents. The structural design of CTB integrated top cover, side wall design, bottom protection and composite fiber backbone are all designed by Xiaomi. The low conductivity coolant, battery management software, Che Yun integrated safety early warning system and high voltage architecture are also designed by Xiaomi.

17. What specific benefits can Xiaomi CTB inversion technical scheme bring?

Xiaomi CTB battery pack adopts the inverted battery cell design. Compared with the traditional upright battery cell, the pressure relief valve faces downwards. With the only nonporous high-strength steel upper cover design in China and the most stringent thermal runaway safety standard in the world, the passenger compartment is completely isolated from the battery compartment in the limit state.

Even if the heat is out of control at 55 degrees Celsius, there is no open flame and heat spread, and the pressure relief valve is facing down and the cover is non-porous, which constitutes the ceiling of the battery safety protection ability.

18. How high is the aerogel content of Xiaomi battery? Is it standard?

Xiaomi SU7 adopts the industry’s top 17 layers of high-voltage insulation protection, and customizes the strongest active cooling technology in the industry: the cooling area of double large surfaces reaches the highest level of 7.8m2, which is four times the industry average. At the same time, 165 pieces of the most advanced aerogel insulation materials in the industry are laid on both sides of the battery cell, which can resist the high temperature of 1000°C at the highest.

During the test, our engineers were extremely confident in innovative materials and processes, and dared to put their hands close to aerogel materials and directly burn them with a 1000°C spray gun flame on the other side, which was still safe and sound.

19. Some netizens wonder whether the thermal management of Xiaomi SU7 can only reach -20℃ because it can adapt to low temperature. Is this true?

At present, there is no strict specification about the working scope of heat pump in the industry. Some enterprises claim that it can be as low as -30℃, but it is not a pure "air source heat pump", but a heater or water source heat pump is working.

It was revealed at the Xiaomi Automobile Technology Conference that -20℃ relies on a pure air source heat pump and can still obtain heat from the air.

If we follow the same caliber of the above-mentioned related companies and add heaters, the overall thermal management ability of Xiaomi Automobile can be as low as -30℃ or even lower. Therefore, Xiaomi automobile can challenge the "king of winter trams", and it can be said that "trams have no fear of winter".

20. Is the Modena platform of Xiaomi Automobile completely self-developed?

The Modena platform of Xiaomi Automobile is a self-developed automobile platform of Xiaomi. There have been rumors that Xiaomi Automobile uses other car factory structures, which is completely inaccurate.

100 "first", "only" and "most" design goals were established at the beginning of the research and development of the modena platform of Xiaomi Automobile. Some achievements were also shared with you at the Xiaomi Automobile Technology Conference, and there are still more achievements. We will report to you in detail when Xiaomi Automobile is officially released.

21. Have you actually achieved the design goal of "100 first, only and most"?

We talked about "design goals" at the press conference. In fact, most of them have been achieved. Because of time constraints, we only talked about some of the leading technologies and functions of Xiaomi Automobile. More points, we will introduce to you in the future until the official release of SU7.

22. What can Xiaomi’s intelligent driving achieve the goal of "entering the first camp in the industry in 2024"?

The intelligent driving of Xiaomi automobile adopts a full-link self-research scheme. Moreover, the starting point of Xiaomi is very high. Based on the latest generation of the underlying algorithm-BEV+Transformer+occupation network, the large model technology is fully integrated into it, and the end-to-end perceptual decision-making large model is applied to the production car for the first time in the world.

23. Xiaomi SU7′ s elk test score of 82km/h is based on what standard?

Xiaomi SU7 elk test was carried out in full accordance with the international standard ISO 3888-2, and the elk test score was 82 km/h. If you are careful, you will find that the road width in the middle section of the test is slightly narrower than the national standard, which makes it extra difficult for yourself. Elk test is a comprehensive test that reflects a series of capabilities such as handling and body stability. After Xiaomi SU7 is officially listed, the media are also welcome to compare and measure it.

24. Will Xiaomi make a beggar-in-a-beggar version in order to lower the starting price?

Please rest assured that Xiaomi Automobile has fully consistent product project criteria, and "experience priority" is always in the first place. Xiaomi SU7 is the standard version.

25. Is a five-star safety collision standard? Is there a difference in collision safety performance between the standard version and the MAX version?

No matter which version of the car, the safety crash test results are top-notch. We chose the most stringent standards to design our products. Xiaomi SU7 series has reached the five-star safety standard of C-NCAP 2024, the five-star safety standard of E-NCAP 2023 and the excellent safety standard of C-IASI 2023 3G+.

26. Does Xiaomi car have only three colors? Will the production version have white and black? Will there be macho powder?

This time, we announced three colors of Xiaomi SU7, namely Gulf Blue, Olive Green and Elegant Grey. All three colors are very beautiful on the real car. Our design team has made great efforts in color research and development and car paint technology.

We also see many users asking if there is a classic black and white color scheme. We do have more colors to choose from, which will be fully introduced to you when it is officially released.

27. Why didn’t Xiaomi consider redesigning a new car logo?

We are very satisfied with the logo design of Xiaomi Automobile, which is in the same strain as the Xiaomi brand logo. It is our important brand asset, and aesthetics is a subjective matter. We will also listen to your different voices with an open mind.

28. Why was the first car called Xiaomi SU7?

"SU" is the abbreviation of Speed Ultra, and "7" is the series positioning determined according to the usual cognitive habits of vehicle positioning in China. The size of the vehicle is about the same as that of BMW 5 Series. High performance is Xiaomi’s gene. Tesla said not to build a slow train, and we did the same. As for how to pronounce it, we also discussed it seriously internally. In the end, everyone thought it would be called "Su 7", just like calling a friend’s name, which is more cordial.

29. Will Xiaomi SU7 be sold globally?

At present, we will focus on the official release and listing in China. But our ultimate goal is to make Xiaomi cars gallop on every street in the world.

30. Will Redmi cars be launched in the future?

Without this plan, at present, we are still focusing on the whole chain of production and sales of Xiaomi car, even specifically, our first car, Xiaomi SU7.

31. When can I see the real car of Xiaomi car in the Xiaomi home around me?

After the official release of Xiaomi SU7, we will provide you with a real car experience in Xiaomi Home in key cities across the country. We are actively preparing for this work, and please wait patiently for a while.

32. Mr. Lei said that Xiaomi had no rivals within 500,000 yuan. Was it a joke or serious?

This is a sentence that General Lei replied to netizens in the comment area at that time. Although it was a joke, it was also serious. At the press conference, we made a number of comparisons including design/performance/endurance/vehicle safety with Porsche Taycan Turbo/ Tesla Model S. The actual comparison results are very clear to everyone, and the pricing of these two cars is also very clear to everyone. We are pragmatic and will not set those outrageous flag, so we are still very confident that Xiaomi SU7 has no rivals within 500,000 at present.

33. Is General Lei focusing on building cars? Do you still have the energy to build a good mobile phone?

Mobile phone is still the core business of Xiaomi and the core foundation of our strategy of "people, cars and homes are all ecological". Mr. Lei is still very concerned about the technology research and development of mobile phone business. Last year, Mr. Lei said that at this stage, his time and energy distribution is roughly that at least a quarter of his time is still spent on mobile phone research and development business, a quarter is concerned about group operation and management, and a half is spent on automobile business. ????

　　The upsurge of online consumption brought by "double 11" has not completely dispersed, and many problems about online consumption have begun to appear. As a new way of online shopping, online celebrity’s "live broadcast with goods" attracted many netizens to place orders, but at the same time, many chaos broke out.

　　"Live broadcast with goods" is tricky

　　Because online celebrity or the stars themselves have their own traffic, bringing goods through them can not only broaden the brand’s popularity, but also guide the merchants to drive the sales of goods. However, the chaos such as false propaganda and brushing in the "live broadcast with goods" has gradually attracted everyone’s attention. The reporter saw on the live broadcast platform that online celebrity, with millions of fans, became the "king of goods" of double 11. A female anchor in the "live broadcast with goods" mask, in just one hour, thousands of people placed orders to buy. Some insiders told reporters that the influence of online celebrity anchor can’t be ignored, but the order data are not all true, some have the phenomenon of swiping orders, and some products exaggerate publicity and mislead consumption.

　　Online celebrity’s false propaganda should be jointly and severally liable.

　　Meng Huixin, assistant analyst of Legal Rights Department of E-commerce Research Center, believes that "live broadcast with goods" in online celebrity is a new e-commerce model compared with traditional e-commerce, so in this process, it is illegal for online celebrity to sell goods through live broadcast platform, or for other e-commerce platform merchants to sell goods through different channels, as long as there are acts of swiping bills and buying comments. In addition, "live broadcast with goods", as a new format of Internet sales promotion, has been admired by many consumers. In the Advertising Law, advertising is defined as the direct or indirect introduction of the goods or services promoted by oneself through certain media and forms. The expression of "live broadcast with goods" is more lively and interactive, and its essence is the same as that of traditional TV advertisements, both of which are advertising behaviors. Therefore, if the goods promoted by the live broadcaster involve the life and health of consumers or the false advertisements of services cause damage to consumers, they need to bear joint and several liability.

　　"online celebrity brings goods" is easy to fall into the dilemma of rights protection

　　Although online celebrity’s "live broadcast with goods" has been welcomed by many consumers, some "online celebrity with goods" have taken advantage of the lack of perfection in the content review mechanism and supervision and management of the live broadcast platform, and made false publicity by virtue of their own traffic, resulting in such problems as fraudulent live broadcast data, too many "three no products", false advertisements, and difficulties in protecting consumers’ rights. Meng Huixin said that due to the poor quality of goods, some payment methods of live broadcast platforms are mostly privately traded through convenient means such as WeChat, and some live broadcast merchants sell fake and inferior goods and then take them off the shelves, resulting in consumers not having purchase vouchers. Once a consumer dispute occurs, the later return and exchange cannot be guaranteed, and it is difficult to protect rights. As consumers, we should first improve our ability to judge commodities, and rationally purchase low-priced and niche commodities; Secondly, consumers should have the awareness of obtaining evidence and safeguarding rights when purchasing goods, and keep pictures and videos recommended by online celebrity as evidence in time; Finally, when encountering the "bottleneck" of consumer rights protection, you can choose to complain to the Consumers Association and other departments, or even bring legal proceedings. Finally, the development of the industry needs parallel platform supervision, the platform should strengthen the management mechanism, and the regulatory authorities need to strengthen law enforcement. (Reporter Zheng Yan)

Although the folding screen did not usher in the expected explosion, the layout of various manufacturers also did not fall. Different from traditional mobile phones, there are various forms of folding screens, including vertical folding screen mobile phones mainly based on Samsung Galaxy Z Filp4 and horizontal folding screen products, but the folding screen products mainly based on horizontal folding scheme are the representatives of this category.

Up to now, mainstream manufacturers in the market have launched their own new folding screen products. At the same time, the unique experience of folding screen has become an important reason why many consumers are willing to start folding screen mobile phones. In terms of software experience, in the face of the 8-inch large internal screen with an aspect ratio of 4:3.55, vivo X Fold+ has also made many deep adaptations. Through this big screen, users can work, entertain and create more efficiently!

The folding screen takes into account both the traditional mobile phone and the tablet experience, and the application gameplay has become more diverse. Take vivo X Fold+ as an example, it can not only support full-screen display of applications, but also support split-screen display, small window form and small window hanging in sidebar.

In applications that support split screen, you can open split screen mode by sliding up with three fingers. In split-screen mode, users can run two tasks at a time. You can chat while bilibili is chasing fans, or video conference while recording work notes, or search while reading …

In addition, in split-screen mode, we can open two additional applications in the form of small windows, which means that we can do four things on the same big screen at the same time, and we can make full use of the advantages of the big screen. This experience is actually very similar to that of a tablet computer, with higher efficiency than that of a traditional mobile phone. The key folding screen is still relatively portable, and the folding volume is similar to that of a straight board computer.

In addition to a variety of multi-tasking experiences, vivo X Fold+ is also more suitable for the experience of folding screens. For example, in split-screen state, three dots in the middle of the screen provide operation options such as quitting split-screen, exchanging application positions, displaying on the right desktop, and switching to split-screen arrangement.

In addition, we can also save two commonly used split-screen applications to the desktop in the form of shortcut icons, so that we don’t need to open the split-screen separately when we use it next time, and it is very convenient to open it directly with one button.

For the small window, after opening the application, you can enter the small window mode by sliding inward from the lower left corner of the screen. In addition to supporting multi-opening tasks, the small window can also be stored in the sidebar, which can be called by sliding the sidebar when necessary. The overall operation is very smooth and easy to learn, and even the first-time user can get started quickly.

We know that folding screen phones have a unique function, that is, screen hovering, but not all folding screen phones support screen hovering, which mainly depends on the design of hinges.

Vivo X Fold+ adopts aerospace-grade floating wing hinge, and the "skeleton" is made of zirconium alloy, which also provides support for the whole hinge structure. The hinge design imitates the wing structure of birds and can be opened and closed smoothly.

In order to achieve hovering of about 60-120, the hinge of vivo X Fold+ is also equipped with NdFeB magnets, which, together with gravity sensors, gyroscopes and Hall sensors on both sides of the fuselage, bring a folding feel with moderate damping.

Hover operation brings more gameplay to vivo X Fold+. For example, when shooting, you can stand your mobile phone on the desktop, and half the screen is used as a "tripod", which is much more stable than hand-held shooting. It is not only suitable for self-timer and video, but also can take some delayed photography and long exposure proofs, which is still highly practical. For people in the workplace, hovering video conferencing will be a good usage. After the mobile phone is placed on the desktop and the screen is folded, the screen will be split in two, and video calls can be displayed at the top, and typing can be performed at the bottom, which is very efficient.

For myself, I don’t usually use vivo X Fold+ to take photos and work, and I like it best to watch video dramas. Similarly, we can hover the mobile phone on the desktop, watch movies on the upper screen, and do some simple video control on the lower screen, such as fast forward and fast backward, pause playback control, video volume and brightness control, and so on.

Finally:

Compared with ordinary mobile phones, folding screens with different shapes are still unfamiliar to most consumers. On the one hand, the price is really not cheap, and the price of 10,000 yuan has discouraged many users. On the other hand, in addition to hardware, software also has a great influence on folding screen mobile phones, which also tests the ability and determination of manufacturers to adapt to the application ecology. Due to the constraints of many conditions, it is a popular trend for folding screens to replace traditional mobile phones. In fact, there is still a long way to go.

Of course, if you are looking for a more novel experience, then vivo X Fold+ is perfect. Vivo X Fold+ has a mature software system, good hardware specifications, and exquisite business design, which is worthy of early adopters.

If you want to escape from the hustle and bustle of the city, but don’t want to go to mature scenic spots to watch the crowds, then it’s better to find another way to experience a camping trip that truly integrates with nature in this spring day when grass grows and warblers fly.

Camping has become a fashionable way of life for young people. Playing on the grass, watching the sunset on the waves and snorkeling the audience fish are comfortable and pleasant, but they also need a lot of preparation, attention and aftermath, and let Xiaobian summarize it for you.

What equipment do you need for camping

1. Tent

Generally, there are three quarterly accounts, four quarterly accounts and alpine accounts. According to the number of users, it can be divided into single, double, triple and multi-person accounts. The most common is the three-season double account, which is commonly used in ordinary leisure camping activities in spring, summer and autumn. The structure is divided into double-layer and single-layer accounts. Double-layer outer account is windproof and rainproof, and the inner account is breathable. The tent poles are divided into glass fiber poles and aluminum alloy poles. Aluminum alloy poles are lighter but more expensive, while glass fiber poles are slightly heavier but cost-effective.

Leisure camping in spring doesn’t require high tents. Just buy 3-4 people around 300 yuan. When choosing, we should pay attention to the fact that the outer account should be sun-proof and waterproof, the inner account should be spacious and breathable, and the weight and volume should not be too large.

2. Sleeping bag

According to different climatic conditions, choose sleeping bags according to the temperature scale (the index of the warm temperature of sleeping bags). The filling medium is fiber cotton or down. Down sleeping bags are more and more popular because they are easy to compress, small in size and light in weight, but the price is also more expensive. Once they get wet, the heat preservation will be much worse, so we should pay attention to moisture prevention. Fiber cotton sleeping bags are less effective in keeping warm, but the price will be much cheaper.

It’s still a little cold at night in spring. You don’t need to bring down sleeping bags this season, just choose cotton ones. When choosing a sleeping bag, it is based on the comfortable temperature scale, and the filler can be fiber cotton, because the fiber cotton sleeping bag is not only much more affordable than the down sleeping bag, but also has the advantages of moisture resistance and simple maintenance. Of course, if you travel by car, it is ok to bring your own quilt.

3, moistureproof pad/air cushion

In order to protect your body, you must pay attention to moistureproof and antifreeze when camping, which is used to isolate from the ground moisture and maintain your body temperature and sleep quality.

Dampproof pad is very important! Its main function is to isolate the ground moisture, prevent moisture and prevent freezing. If you want to spend the night safely, you can’t do it without a damp-proof pad. At present, there are generally two kinds of foam moisture-proof mats or self-inflating mats on the market.

4, wash bag

A washing bag that can hold towels, toothbrushes, toothpaste, combs, soaps, shampoos and other toiletries is a must-have item for outdoor travel. It is best to choose the style with multiple storage bags and built-in lenses, which is convenient to use.

5, wind rope

The function of windbreak rope is to fix the external account. If not, it will be windy and windy at night, so you can’t sleep. If it rains, we will watch the sea in the tent.

6. Ground nails

Diding is to a tent what the foundation is to a house. Without Diding’s tent, the wind blew and ran away. It is even more unsafe if it is windy and rainy.

7. Rainproof cloth/shade cloth

There is nothing to say about this, just to protect against wind and rain. If it is sunny, it will be more free to take shade cloth to build a simple shed than in a tent.

8.pillows

Children’s shoes that are inseparable from pillows should be prepared by themselves, or DIY with clothes and other items is also good.

9. Camping lights

Outdoor lighting includes camp lights, flashlights and headlights. You must remember to bring one kind of lighting tool, which will be used for camping at night. Camp lights are the most practical choice for outdoor camping. They are small, light and easy to carry.

Even if you don’t walk at night, you still need lamps when you walk around. Besides, if you play cards and games at night, how can you be high without camping lights?

10. Outdoor first-aid medicine box

Specifically, a well-stocked first aid kit should include:

Bandages, gauze of various sizes, antibiotic ointment, sterilized dishcloth, washing liquid, painkillers, tweezers, scissors and knives, spray for relieving sunburn pain, and antidiarrheal drugs. So, what accidents will we face during camping in spring-the most common ones are cuts and bruises. When we are playing outside and camping, some trivial things may become dangerous, such as: shuttling through small trees, prickly Woods, encountering cacti, cooking outside, bonfire parties, insect bites, etc., which may cause us unexpected minor injuries, so we should make full preparations in advance.

When you encounter cuts and abrasions, you may wish to use bandages, and at the same time, you can use clean and disinfected rags and antibiotic ointment. Hydrogen peroxide comes in handy when cleaning wounds.

If you sit close to the bonfire and ashes blow into your eyes, you can wash your eyes with salt water. This is a good way.

When bitten, scratched or cut by mosquitoes, you might as well use painkillers, which has a good effect.

If you are unfortunately stabbed by a thorn or a small piece, you can ask tweezers to help you pull out the small piece and thorn, and then use scissors or a knife to cut the bandage and rope.

When you have a headache, you can use aspirin and acetaminophen to relieve the pain. When you have gastrointestinal problems and your stomach is uncomfortable, you can take antidiarrheal drugs prepared in the first aid kit.

In addition to the drugs mentioned above, you need to prepare aloe cream to relieve the pain immediately after sunburn; In hot summer, you should arm yourself with lip balm and sunscreen to protect your skin. In addition, it is also very important to prepare a first-aid medicine box for snake bites.

Finally, Xiaobian wants to remind campers that the first-aid medicine box should be checked regularly, and then the necessary supplies should be added, and the expired drugs should be replaced immediately. Remember: whenever you go camping, you must prepare an adequate and practical first aid kit in advance and be a smart camper.

How much does camping cost?

In a parent-child TV program, the scene of participants building tents is still fresh in everyone’s memory. There is a hole in the spacious tent, and there are two rooms, one for bedroom and the other for cooking.

In fact, the simplest camping doesn’t need such a big tent, and the simplest two-person tent is enough. Camping tents are divided into three-season tents (spring, summer and autumn), four-season tents and alpine tents, and the three-season tent is usually used for camping. If you don’t look for well-known outdoor brands, you can win a cheaper double tent online for more than 100 yuan.

There are three kinds of sleeping bags: cotton sleeping bag, fleece sleeping bag and down sleeping bag. The price of cotton sleeping bags is generally about 100-200 yuan.

Choosing a sleeping bag should be based on the specific conditions of the campsite, mainly depending on the comfort temperature. Generally, the comfort temperature of a thick cotton sleeping bag is about -8℃ to -10℃, but it is just right to use it at 0℃ to -5℃. When the weather is warm and hot, the sleeping bag liner and ordinary air conditioning quilt are enough.

Many online shops sell camping suits, the most famous of which only cost 300-400 yuan, including tents, sleeping bags for two, inflatable cushions, tent lights, flashlights and other large items needed for camping.

Another important content of camping is cooking by yourself, so stoves are essential. The average stove head price is less than 100 yuan, and a complete set of cookware for more than 4 people is about 200 yuan.

If there is a hiking plan, large-capacity hiking bags, trekking poles, headlights, etc. are essential. 50-70L hiking bag is suitable, and the price is about 200-600 yuan, and the basic price of hiking poles is between 70-160 yuan.

In other words, a set of the simplest and complete camping equipment only needs about 600 yuan, and of course, necessary items such as maps, compasses and matches also need to be carried. As most camping sites are free, accommodation is basically free. Accommodation in Hong Kong and Macao costs thousands of dollars. Once camping, the equipment fee is basically earned back, which is really an excellent choice with unique flavor and saving money.

These things can’t be done

Taking a tent and camping in the seaside or mountains with your lover or friends is a very romantic thing for many people. Therefore, it is understandable to add some small links that can create a romantic atmosphere in the process of implementation, but note that some imagination is not suitable for turning into reality, otherwise your beautiful camping life will be ruined.

There is a tent by the water.

It is an ideal camping life for many people to pitch a tent at the water’s edge, by a gurgling stream or on a beach at low tide and fall asleep with the gentle sound of water or waves. Have you ever dreamed of it? However, it is very dangerous to wake up and put your tent near the water. Rising water, flash floods and storms may come at any time, putting you in danger. Therefore, tents should not be tied near water.

In the candlelight by the bonfire

Playing a guitar by a raging bonfire, or lighting candles in a tent to talk with your lover or friend, are you going to try it in this camping trip? However, don’t forget that most tent materials are not fireproof, and some of them burn very quickly. Therefore, don’t use open flames, including candles, in tents, and light bonfires far away from tents. If you want to create an atmosphere, you can use camp lights or headlights instead. If you can, put a fire bucket full of water outside the tent in case of emergency.

Look at the stars on the high hills.

In the high hills, the wind is also quietly, and in the deep and dark sky, stars are like gems, blinking. So, you decided to set up your tent on a high hill and prepare to enjoy the rare night scenery quietly? Please don’t do this. The weather is changeable, the weather is unpredictable, and the high wind strikes first, which will make you unprepared.

Casual clothes and trousers on a spring night

Want to wear casual clothes when camping? I advise you not to do this. In spring, there are many insects outdoors, especially at night, it is best to wear close-fitting long trousers to avoid mosquito bites and branches hanging. If the clothes are wide, you can tie up your trouser legs and cuffs.

Therefore, you need to be careful when choosing a camp. When determining the location of Anza tent, first take out the inflatable cushion and try to spread it on the target ground, and lie down to check whether it is too inclined or has obvious protrusions. In addition, the campsite should be as close to the water source as possible to facilitate washing and cooking.

In addition, it is also necessary to beware of mosquito "harassment". Especially in the south, mosquitoes are inevitable in spring, summer and autumn. This situation will be more serious at night when there is no wind. Therefore, when choosing a camping site, you should not choose the side of a dead pond and dense grass, which are the "hardest hit areas" for mosquito breeding. In addition, mosquitoes will not gather in ventilated places, so when choosing a camp, you can choose a place close to the wind, such as between two mountains or a ventilated tunnel. It is best to prepare some mosquito bite drugs, such as unparalleled drops and essential balm, to prevent mosquito bites.

What else should I pay attention to?

1. In early spring, the temperature is unstable and the temperature difference is very large. When camping, it is inevitable to encounter cold and rainy weather, dense fog, strong convective weather and lightning weather. Therefore, it is necessary to pay attention to wearing appropriate clothes, not too much, not too little. Generally speaking, you must obtain the local climate information of the tourist destination in advance, and remember to bring a warm coat with you to prevent catching cold.

2. Pay attention to hygiene when going out, and don’t stay in crowded places. Choose places with good air quality, such as climbing mountains, or going to the seaside and forests.

3. In early spring, rain is inevitable. Rain gear is something that must be carried with you when camping. It is best to bring a small folding umbrella or a disposable convenient raincoat. When playing outside in rainy days, you should pay attention to anti-skid, anti-fall and anti-fall when taking pictures, and put personal safety first.

4, shoes must be comfortable, ladies do not wear high heels when traveling. If your feet are red and swollen, soak your feet with hot water before going to bed to dredge the meridians.

When you go out, remember to keep a booklet with you, which records some important contact numbers and other information, which will be of great use when you need help. If it is waterproof, so much the better!

6, spring is a humid season, mosquitoes and bacteria are particularly easy to breed, therefore, we should try to avoid drinking raw water and eating unsanitary food.

7. If you have a history of motion sickness, seasickness and airsickness, you should not eat too much before going out. You should take drugs such as halo tablets in advance or chew gum and foods containing glucose, choose some ventilated places to sit, and deal with them immediately if you are uncomfortable.

8. If there is lightning in the hotel, disconnect the power cord of the indoor electrical appliances and close the doors and windows, so that people can keep a certain distance from the doors and windows.

9, don’t sit in a cool and humid place, so as not to get wet and get sick.

10. People with a history of allergies should pay more attention to the spring outing sites they choose, avoid places with flowers as much as possible, or take anti-allergic drugs such as chlorpheniramine or Anqimin orally in advance to prevent pollen allergy.

11. It’s a good time for outdoor photography with beautiful spring and sunny weather. Before traveling abroad, it is best to check the performance of the camera. The battery should be fully charged and never let the camera get wet.

12, because it is difficult to accurately estimate the length of climbing, should prepare enough drinking water and food and commonly used drugs, such as mosquito repellent, antidiarrheal drugs, mercurochrome, etc.

13, carrying lighters, binoculars, multifunctional knives, etc., can get more fun in the wild.

Matters needing attention after camping

1. Camp cleaning after camping

To protect the natural environment in the wild, the fire must be completely extinguished when the camp is withdrawn. Garbage waste should be taken out as far as possible and put in the designated place. When it is impossible to take it away under special circumstances, the garbage can be dug and buried.

2. Cleaning and maintenance of camping equipment

Tent: After each camping trip, clean up the internal and external tents, tent poles and ground nails. Generally, tents can’t be cleaned by washing machine, but can be washed with non-alkaline cleaning agent. After the tent is finished, it is placed in a ventilated place to dry in the shade, and then placed in a dry and cool place.

Sleeping bag: dry the sleeping bag as much as possible after use and keep it dry. Give priority to local cleaning, minimize the overall cleaning times, and avoid lowering the use index of sleeping bags. Hand washing is recommended, and try not to twist it. Dry it naturally after cleaning to avoid high temperature drying. After drying, pat it gently and store it after natural expansion.

　　CCTV News:Since 2016, China has stipulated that the use of mobile phones must be registered with real names. However, for a long time, there are still a number of mobile phone cards that do not comply with the regulations of real-name registration system, and have no real names or fake real names, so they are called mobile phone black cards.

　　Such a mobile phone card has also become the most popular crime tool for criminals, because even if the police track the mobile phone number, it is difficult to track the offender himself. Where did such a mobile phone card come from?

　　Card vendors told reporters that users only need to upload their ID cards online to handle these virtual operator cards, and they can also pass them with other people’s ID cards. Many people can’t help but break into a cold sweat when they see this. May my ID card information be registered as a "black card"?

　　Mobile phone "black cards" are still publicly sold online.

　　The reporter searched related qq groups with the keyword "Beijing mobile phone number" on qq, and various qq groups popped up immediately. The introduction of many groups clearly wrote: "Sales Unicom, Mobile and Telecom mobile phone numbers, cash on delivery".

　　Subsequently, the reporter met a card vendor in Xingtai, Hebei Province on the grounds of purchasing a mobile phone card. He told the reporter that the operators of mobile, China Unicom and telecom entities are now in tight control, and this so-called "regular card" must go to the business hall in person, and the face scanning can only be processed after it is consistent.

　　In addition to the "regular cards" in the card vendors’ mouths, there are also "irregular cards" with numbers of 170 and 171, etc. On the back of these cards, they are also marked with "Registration with real identity information" and "Please show me your valid certificate to handle the number".

　　It is understood that these cards belong to virtual operator "Longma Mobile" and "Telephone World" respectively. Card vendors told reporters that users only need to upload their ID cards online to handle these virtual operator cards, and they can also pass them with other people’s ID cards.

　　Then, can virtual operator find out if someone else’s ID card is used to cheat mobile phone cards?

　　Langma Mobile Human Customer Service Staff: It is really impossible to verify whether the uploaded photos are me or not, but as long as the uploaded photos meet the requirements, they can be approved.

　　After testing, the reporter found that these calling cards in virtual operator can be used normally, whether they are calling, sending short messages or registering online platform accounts.

　　Police in Chaozhou, Guangdong province detected the case of "black card" of mobile phone.

　　For a long time, a large number of criminals have been hiding behind the "mobile phone black card" and doing evil at will. In order to crack down on crimes from the source, the public security organs have taken a high-pressure attack on "black cards of mobile phones". Last year, police in Chaozhou, Guangdong Province cracked a typical case of "black card of mobile phone".

　　At the end of 2017, Guangdong Chaozhou police received a report from Chaozhou Mobile Company, saying that it found that there were about 2,000 Chaozhou mobile phone numbers that were connected to the network in 2015.

　　Police handling the case of Criminal Investigation Brigade of Xiangqiao Public Security Bureau: These cards took advantage of the loopholes of the mobile company, and immediately applied for card downtime protection after handling the 588 yuan package. They only needed to pay the card protection fee of 5 yuan every month, and then these cards bought traffic through the online APP, and cashed these phone bills online, thus making illegal profits.

　　Soon, a criminal gang with a large number of mobile phone cards, registered WeChat accounts and other online accounts for profit surfaced. In the end, the police successfully arrested 16 suspects and seized nearly 1.7 million sets of black cards for mobile phones.

　　After examination, the gang defrauded Chaozhou Mobile Company of nearly 2 million yuan, and registered 5.07 million online accounts.

　　At present, the people involved have been sentenced to imprisonment for the crime of infringing citizens’ personal information and the crime of contract fraud.

　　Downstream "black production" needs big mobile phone "black card" as an accomplice

　　What are these mobile phone cards used for? After an in-depth investigation by CCTV reporters, the industrial chain of a mobile phone black card was finally clearly presented.

　　The reporter learned that there are three main sources of mobile phone black cards, one is the entity operator card, the second is the virtual operator card, and the other is the overseas calling card. Mobile phone black cards are mainly sold offline, while online sales are mainly carried out through instant messaging tools or e-commerce platforms.

　　It is understood that at present, mobile phone black cards are widely used in cybercrime, because a large number of network platforms need mobile phone number registration. For example, many criminals use a device called "Cat Pool" to control a large number of mobile phone black cards, register accounts on various network platforms, and illegally profit from various network activities.

　　Weng Jie, deputy detachment leader of the network police detachment of Chaozhou Public Security Bureau, Guangdong Province: Internet fraud, online gambling, or water army, or network bonus hunter, these black products are in great demand for this kind of mobile phone black card.

　　Yang Dong, deputy dean of the Law School of Renmin University of China: These online illegal products illegally take ID cards and personal information, register a large number of mobile phone numbers, and make illegal profits. If this profit reaches a certain amount, it is suspected of theft. If it is obvious and subjective, it is suspected of fraud.

　　At present, on the one hand, relevant departments are stepping up their efforts to crack down on mobile phone black cards, on the other hand, they are advancing the legislative process and trying to eliminate the problem of mobile phone black cards from the source.

　　In fact, we often receive harassing calls and fraudulent calls, many of which are paragraphs 171 and 170. These are all telephone numbers in virtual operator, and it is so easy to handle calling cards with these numbers.

　　Experts believe that from the perspective of industry governance, the leading operators should strengthen the management of virtual operator and stop the loopholes in the operation of virtual operator. If we want to restrain virtual operator effectively, we must punish him severely enough. Only when the meat hurts will they dare not be willful.
