Officer Lei announced： Xiaomi SU7 will be unveiled on December 28th.

On December 25th, Lei Jun, founder and CEO of Xiaomi Technology, issued a message on the official social platform, saying: "This time, only technology will be issued, and no products will be issued. See you at 2 pm on December 28 (this Thursday). " The picture is the chassis of the vehicle. It is worth mentioning that the official Weibo of Xiaomi Automobile has also been officially launched, and the poster has been released simultaneously with the text "See you at 2 pm on December 28." . According to the available information, Xiaomi SU7, the first medium and large car owned by Xiaomi Automobile, will be unveiled on the same day (December 28th).

The new car has been declared before, and several versions will be launched, which are divided into three versions: standard version, Pro and Max. Available in four endurance versions of 628km, 668km, 800km and 750km.

Presumably, you are already familiar with several declaration drawings of Xiaomi SU7, but as a rule, let’s simply review it. Xiaomi SU7 was designed by Li Tianyuan, a designer of BMW iX, and applied the popular elements at the design level. The whole car is concise and sporty. Specifically, the car adopts a rounded polygon headlight group, and the interior adopts a light cavity structure similar to a herringbone element, which is matched with a large trapezoidal air inlet below, so that the recognition degree is high.

From the side of the car body, the car uses embedded hidden door handles to optimize the drag coefficient of the car. At the same time, the car adopts double five-spoke rim shape to enhance the sporty atmosphere. In terms of tail, Xiaomi SU7 adopts a penetrating taillight group, which is fashionable and personalized with the unique diffuser decoration below. In terms of body size, the length, width and height are 4997/1963 /1440mm and the wheelbase is 3000mm respectively.

The new car is expected to provide three versions: basic version, Pro and Max, which are different in configuration, such as laser radar, which is also the usual practice in the industry. In terms of power, Xiaomi SU7 will provide a front and rear dual-motor version and a single-motor version. The former has a front and rear motor power of 220 kW/275 kW; The motor power of the latter is 220kW.

At the same time, according to the announcement information, Xiaomi SU7 will be equipped with two battery pack options, 73.6kWh and 101kWh, of which 73.6kWh is a lithium iron phosphate battery provided by Foday, with a 400V voltage platform, battery life of 628km and 668km respectively, and the total mass of the battery pack is 579kg；; 101kWh is a ternary lithium battery provided by Contemporary Amperex Technology Co., Limited. It adopts 800V high-voltage platform, and its battery life is 800km and 750km respectively, with a total mass of 645.8kg.

The security of M7 is ＂far ahead＂ because Contemporary Amperex Technology Co., Limited is far ahead.

After Huawei’s Mate60 Pro flagship mobile phone became popular all over the network, the M7, which was jointly built by Huawei and Cyrus, also ushered in its own "Mate moment" and became another "far ahead" product in Yu Chengdong’s mouth.

One of the core selling points of M7 is "super security". At the press conference, when Yu Chengdong mentioned "five-fold safety structure, safety should be high above", he cued Contemporary Amperex Technology Co., Limited, a battery partner under the stage. Obviously, Yu Chengdong’s confidence comes from Contemporary Amperex Technology Co., Limited to a great extent. Compared with high-level intelligent driving and price, the author is more concerned about how M7 can achieve a far-reaching lead in the century-long problem of battery safety.

Battery safety is "far ahead", Contemporary Amperex Technology Co., Limited’s "handwriting" and Huawei’s "wonderful pen"

How safe the battery pack is depends on whether there are top-notch battery technologies, reasonable battery protection measures and effective thermal runaway solutions.

Based on Contemporary Amperex Technology Co., Limited’s assistance in battery safety technology, the battery pack of the world M7 has passed a number of thermal safety experiments. Just as Yu Chengdong said, "the battery pack, circuit design and safety overheating protection all reach the highest level". In fact, Contemporary Amperex Technology Co., Limited not only helped Huawei develop this extremely safe battery, but also relied on the extreme manufacturing capacity to mass-produce it quickly. This also proves that Yu Chengdong’s "far ahead" and "safety is paramount" are not empty talk.

The test standard is "far ahead" and the safety is "high above"

Yu Chengdong mentioned that the sub-frame is the lowest point of the chassis, which fundamentally reduces the risk of battery scratching. The "high" here is not only as simple as the structural location layout, but also because Huawei and Contemporary Amperex Technology Co., Limited have set "high safety standards" ahead of the industry.

Contemporary Amperex Technology Co., Limited’s battery pack has obtained extremely high mechanical strength through the unique CTP technology reinforced box design. The test results of this battery far exceed the national standard several times.

For example, in the vibration test, the national standard requires to simulate the mechanical vibration test of 300,000 kilometers of the battery wrapped in the whole vehicle for 10 years, and Contemporary Amperex Technology Co., Limited has also met Huawei’s unique high-standard speed bump vibration test requirements on the basis of the national standard; In addition, the test results of key indicators of batteries such as collision test and extrusion test all exceeded the national standard several times, and performed well.

It’s not hard to understand why, in the face of doubts, Yu Chengdong can confidently express that he is "not afraid of any slander", and even threatened to ask the world that the new M7 is far safer than the 500,000-class mainstream luxury car currently on sale.

Technology is far ahead, and Contemporary Amperex Technology Co., Limited is the guarantee of high performance.　　

In addition to safety, Contemporary Amperex Technology Co., Limited also added a lot of black technology to the 41.89kWh ternary lithium battery in Wenjie M7.

For example, with the help of Contemporary Amperex Technology Co., Limited’s CTP technology, the M7 can fully demonstrate the high performance of pure electric mode. Contemporary Amperex Technology Co., Limited has optimized the structural parts of battery pack. By using the structural parts made of composite materials and the lower box made of aviation aluminum, the energy density of the battery pack has reached 160Wh/kg, which can easily achieve the excellent effect of battery life of up to 230 kilometers.

In addition, Contemporary Amperex Technology Co., Limited achieved extremely high discharge power by optimizing the battery cell design, and reduced transmission loss by optimizing the whole package high-voltage connection and reducing power consumption at the Pack level. Therefore, this battery pack can provide continuous acceleration power of 315kW and maximum torque of 720N·m for the M7, and its zero-hundred-acceleration is as low as 4.8 seconds, and its power performance is comparable to that of a 3.0T displacement twin-turbo luxury fuel vehicle.

Write at the end:

Ten thousand people hold bows and shoot strokes together, all of which are successful.

Whether HI mode or Smart Choice mode, Huawei gives priority to cooperation with Contemporary Amperex Technology Co., Limited. Obviously, behind the M7 fire, Huawei and Contemporary Amperex Technology Co., Limited share the same idea, that is, the ultimate scientific and technological innovation and the unremitting pursuit of "high above" safety.

Recently, brands such as Aouita and Wenjie invited Contemporary Amperex Technology Co., Limited’s "platform" at the press conference. After all, Contemporary Amperex Technology Co., Limited’s market share of power batteries ranked first in the world for six consecutive years. In the future, consumers may really want to know whether they are equipped with Contemporary Amperex Technology Co., Limited’s batteries before purchasing electric vehicles.

Xu Lin, President of Sailisi Automobile Co., Ltd. (rotating)： Building a new energy car in China and creating a global smart car brand.

Acceptance speech:　

It is a great honor to be elected as "Top Ten Influential People of Chongqing Manufacturing Industry". I would like to thank the leaders of the Propaganda Department of the Municipal Party Committee, the Municipal Economic and Information Committee, the Chongqing Daily Newspaper Group and the upstream news for organizing this selection activity, and also thank the jury.The experts’ recognition of me!

Last month, Jin Kang New Energy Automobile Co., Ltd. was renamed Sailisi Automobile Co., Ltd., the headquarters of Xiaokang Group and related business clusters of Sailisi moved to a new location, and our customer M5 also achieved the fastest record of "delivering more than 10,000 cars in 87 days". These achievements can not be achieved without the care and support of leaders and partners from all walks of life.

We will continue to focus on the development of high-end smart cars and contribute to the transformation, upgrading and high-quality development of Chongqing’s automobile industry! thank you

Building a car: Sailis lays out two smart factories to develop new energy vehicles.

On December 23rd last year, Sailis Automobile Co., Ltd. (hereinafter referred to as "Sailis") officially released its high-end smart car brand AITO, and the first model M5 was delivered in March this year. By the end of May, the cumulative delivery exceeded 10,000 vehicles.

Wenjie M5 is produced in Sailisi Liangjiang Smart Factory, which meets the industrial 4.0 standard.

What standard is Industry 4.0?

Xu Lin said that the Sailisi Liangjiang Smart Factory, which was put into use in 2019, has the world-class high-standard intelligent manufacturing capability, and has achieved a high degree of automation and intelligence. It has more than 1,000 intelligent robots, 100% automation of key processes, and 24-hour online inspection, which effectively reduces labor costs while making manufacturing accuracy and product quality reach first-class standards. It was awarded the "Lighthouse Factory" in Chongqing in 2021.

In order to avoid the potential danger caused by battery PACK operation under high voltage of more than 300 volts, the production module in the battery pack workshop of Liangjiang Smart Factory is produced by automatic AGV, and the most advanced precision high-speed aluminum wire welding technology is adopted in the key welding process, which realizes automatic on-line monitoring of welding.

"Such a factory guarantees the rapid production and high-quality delivery of our vehicles," he said. In addition to Liangjiang Smart Factory, we are building a second smart factory in Fenghuang, Shapingba District, which is also built according to Industry 4.0 standard. It is expected to be completed and put into use in the second half of this year, with a maximum annual production capacity of 150,000 units.

R&D: Cross-border integration of Huawei and Cyrus creates three precedents.

On May 29th, the reporter went to the headquarters of Xiaokang Group in Shapingba District Enterprise Innovation Service Center.

New headquarters, new starting point.

"The relocation of the headquarters of Xiaokang Group and its related business clusters to new homes is a new stage of development for Celestial Automobile at a higher starting point, and it is also a new starting point for Celestial to make efforts to lead global intelligent enterprises." Xu Lin said.

In December 2017, Xu Lin was transferred from Chief Technology Officer of Xiaokang Group to Celes, and began to transform new energy vehicles from traditional car tracks.

Xu Lin said that traditional cars are different from the new forces of the Internet. Internet companies have certain inherent advantages in entering the new energy automobile industry. First, they have their own scientific and technological attributes, and they have certain advantages and persuasiveness in the intelligent aspects of vehicles, such as autonomous driving and intelligent cockpit. Secondly, many technology companies have their own relatively mature user circles and their own fans, so it is easier to find their target audience after the vehicle is built.

Traditional car companies have a complete vehicle supply and production system, and the established brand reputation, vehicle performance experience, technical strength and workmanship have occupied certain advantages.

At the same time, traditional car companies have accumulated many years of experience in vehicle chassis, power, interior and exterior design, and both adjustment and design are quite mature.

"Cyrus has a good partner, Huawei." He said that many people say that the cross-border integration of Huawei and Cyrus is a wonderful move. Combining the strengths of all parties, it will become a global intelligent leading enterprise in the future. I agree with this statement.

The transformation of new energy automobile industry shows a trend of borderless integration, and ecological development and mutual win-win are more important, and the cross-border alliance between automobile enterprises and technology companies is bound to be further strengthened. The cooperation between Cyrus and Huawei is also the general trend, and the pragmatic values of "customer-centered, quality first" are the consensus of the two sides, and the two sides have already started cooperation in 2019.

At present, Celestial and Huawei, through the mode of mutual empowerment and in-depth cooperation, further promote cooperation in the field of intelligent terminals around technologies, products and channels, jointly create high-performance and intelligent mobile travel solutions, and integrate the digital world into every car.

Both Cyrus and Huawei are "technology houses" that focus on technology research and development. Huawei is a global leader in scientific and technological innovation and is committed to building a smart world with the Internet of Everything.

Cyrus also pays attention to the investment in research and development, and has mastered more than 1,000 new energy-related technology patents. It is also the first enterprise in China to master the core three-electricity technology and have the qualification to produce new energy vehicles. It is precisely because they have the same pursuit in the technical field that the cooperation between the two sides is quite effective.

Huawei has more than 5,000 experience stores in China and 730 million smartphone users, which can provide a huge traffic portal for the sales of intelligent products.

"The cross-border integration of our joint business with Huawei has created three precedents." Xu Lin said: First, it has created a precedent for the deep integration of new energy automobile enterprises and ICT technology enterprises; The second is to create a precedent for cars to enter mobile phone stores for sale, and realize the first channel interoperability between technology brands and automobile brands in the world; The third is to create a precedent for the release of mobile phones and cars together.

Planning: The M7 will be mass-produced soon, and a number of mid-to-high-end smart models will be available in five years.

Recently, Celestial Phoenix Smart Factory is working overtime for the final debugging stage.

"Wenjie M5 is produced in Liangjiang Smart Factory, and the upcoming Wenjie M7 will be produced in Phoenix Smart Factory." Xu Lin said. The M7 is positioned as a "luxury smart large electric SUV" and will be officially released soon.

"For the M7, which is about to be mass-produced, there has been a solid foundation and good reputation laid by the M5 before, and with the technical support of Huawei, we think the future can be expected." 　

At present, Chongqing’s automobile industry has a huge scale and outstanding industrial advantages. Sailis will actively respond to the strategy of building a world-class automobile industry cluster in Sichuan and Chongqing, closely follow the new round of scientific and technological revolution and the trend of "new four modernizations" of automobiles, and accelerate the digital transformation of enterprises.

"We will still adhere to the concept of self-sustaining technology, maintain an open and cooperative mentality, actively cooperate with outstanding enterprises in relevant chains, promote the optimization of the whole industrial chain, and jointly promote the development of the new energy automobile industry." He said that Cyrus will firmly promote the automobile energy transformation and create a smart mobile life, adhere to the in-depth cooperation with Huawei, and strive to become a global smart car brand enterprise. In the next five years, it will plan a variety of mid-to-high-end smart models to meet the needs of more users.

Xu Lin said that in the future, Sailis will still take users as the center, define car functions based on user usage scenarios, define configuration and technical solutions based on functions, and divide cars into hardware bases, software bases and application layers to gradually realize "software-defined cars" and realize "pluggable hardware, programmable scenes, ecology on demand and self-evolution of the system".

Supervising the 6-board demon was tortured by the soul.

　　On Thursday (November 16th), the three A-share indexes weakened collectively, with a total turnover of 850.7 billion yuan in the two cities, shrinking by 139.3 billion yuan from the previous trading day. As of the close,Down 0.71%,Down 1.23%,It fell by 1.85%.

　　In terms of plates,、, photoresist, etc. are among the top gainers; BC、, optical modules, etc. were among the top losers.

Many foreign investors expressed optimism.

　　On Thursday, the market failed to hit the 3080 resistance level, which was an important support level in the early stage. After falling below it, it formed an important counter-pressure level, and it was also a 60-day moving average. It was not easy to stand up effectively at once.

　　UbsChina’s stock strategyLei Meng said that since the third quarter, China’s national debt, yield to maturity, has rebounded, and the commodity price index has also rebounded, indicating that they may be pricing China’s macroeconomic rebound.

　　"The positive impact brought by the continuous efforts of policies will continue to be reflected, and A-share earnings are expected to continue to rebound in the next six months, thus driving the A-share market to usher in repair." Lei Meng said.

　　It is believed that although the A-share market has rebounded obviously in the past few weeks, this is only a repair of the previous oversold, and the subsequent A-shares are still worthy of optimism. In the investment direction, the fund said: "We are optimistic about the technology sector that really benefits from the rapid development of the AI industry, the high-end manufacturing sector with a high level of prosperity and continuous overweight policies, andMedicine and other sectors with steady growth rate. "

The 6-board demon suddenly fell.

　　In the case that the market wind was suppressed on Thursday, the old hot.I began to show fatigue. I walked out of 6 days and 6 boards before.Conceptual bibcockOn Thursday, it suddenly fell below the limit, with more than 20,000 orders closed, and the turnover exceeded 600 million yuan, with a cumulative decline of over 15% in the past two trading days.

　　On October 26th, on the interactive question-and-answer platform, it was indicated that some pallet products in the company’s automobile lightweight business passed.Enterprises indirectly supply series products to the world. At present, its proportion in the company’s automobile lightweight business is not high, so investors should pay attention to investment risks.

　　Since then, the company’s share price began to change, and it closed up 7.6% on October 31. Since then, although it has been mixed, the bottom has been rising. On November 7, a word board suddenly appeared, and after six trading days, it went out of six consecutive boards, with a cumulative increase of over 77%.

"soul torture" in Shenzhen Stock Exchange

　　The stock price change has also attracted regulatory attention. On November 14th, Haomei New Materials received a letter of concern from Shenzhen Stock Exchange, which focused on automobile lightweight business.

　　Shenzhen Stock Exchange requires the company to explain the business development of automobile lightweight business, and at the same time explain whether the company has direct cooperation with BMW, Huawei and other companies, whether it is a supplier of BMW, Huawei and other companies or only a supplier of related enterprises.

　　On November 15th, Haomei New Materials stated in the reply letter that the company’s current automobile lightweight business mainly includes pallets, anti-collision beams and sub-frames.Materials and components of components, shock-absorbing brackets, power brackets and other products, among which battery tray and anti-collision beam materials and components are the most important products.

　　In the above reply letter, Haomei New Materials stated that most of the lightweight materials and components provided by the company need to be processed and assembled by enterprises and then supplied to the OEM, and the company’s position in the supply chain is the second-tier supplier or the third-tier supplier of the OEM.

　　Haomei New Materials also said that BMW, Mercedes-Benz, Honda, Toyota, Guangzhou Automobile Aian mentioned in the investor relations record form,, Huawei Wenjie, Changan and other automakers are not direct customers of the company, and the company does not directly sell related products to the above automakers. The corresponding direct customers of the company are, casma,Such as auto parts enterprises, the related products supplied by the company need to be processed and assembled by the above-mentioned auto parts enterprises before they can be supplied to the automobile factory.

　　As of September, 2023, the revenue from the lightweight business of Haomei New Materials Automobile was 840 million yuan, accounting for 19.81%.

　　Haomei New Materials specifically pointed out that the increase in the shipment amount in October 2023 compared with January-September 2023 was mainly due to the increase in the company’s shipments through parts companies after mass production of M7 in Wenjie.

"Cross-border" optical communication was also inquired.

　　In addition, Haomei New Materials previously disclosed that the company plans to cut into the field of optical communication.

　　According to the foreign investment disclosed on November 6,, Haomei New Materials plans to make a D round investment in Sols Optoelectronics at US$ 2.6179 per share, with an investment amount of US$ 40 million (about RMB 290 million according to the current RMB exchange rate).After the exercise, it acquired 15,279,400 shares of Sols Optoelectronics, accounting for about 5.79% of the shares of Sols Optoelectronics after the investment was completed. Haomei New Materials said that this investment in Sols Optoelectronics, the world’s leading supplier of optical communication components, will help the company share the opportunities brought about by the rapid development of optical modules.

　　This investment was also inquired by Shenzhen Stock Exchange, asking Haomei New Materials to explain whether to invest in Sols Optoelectronics to acquire its relevant equity or subscribe for its convertible bonds, the reasons and necessity of the company’s cross-border acquisition of assets in optical communication-related fields, and whether the company has the feasibility of the above-mentioned cross-border acquisition in terms of staffing, technology research and development, market development, etc., and whether there are speculative concepts and hot spots.

　　In this regard, Haomei New Materials replied that the investment in Sols Optoelectronics is due to its optimistic development prospects for the optical module industry. After the investment is completed, the company will not participate in the daily operation and management of Sols Optoelectronics. However, it should be noted that Haomei New Materials has no relevant reserves in personnel allocation, technology research and development, market development, etc. in the field of optical communication.

　　Fierce game of hot money seats

　　Some market participants said that hot money speculation pays attention to a "hazy beauty", which is often referred to as the imagination space. After continuous pulling, there is an impulse to cash in at a high level, and the expectation of overlapping imagination is broken, and short-term funds naturally profit and flee.

　　From the data of the Dragon and Tiger List on Thursday, the top five seats of Haomei New Materials Trading were dominated by the hot money business department. The net purchase of the top five seats was 45.73 million yuan, and the net sale of the top five seats was 54.55 million yuan.

After NMN, AKG, an epic anti-aging substance, has become a new anti-aging force.

An internationally renowned scientist at Harvard Medical School, one of the most influential figures in Time magazine, and the best-selling book Life: Why We Aging — — And why we don’t have to age, David Sinclair (David Sinclair), an anti-aging tycoon, followed NMN and resveratrol to promote another life-prolonging anti-aging substance on Twitter — — α -ketoglutaric acid (AKG)

After NMN, AKG, an epic anti-aging substance, has become a new anti-aging force.

The "epic" anti-aging substance AKG can actually reverse the "aging clock" for 16 years.

On September 1st, 2020, the world’s first professional research institute on aging — — Barker Institute of Aging published the research on AKG’s anti-aging in Cell Metabolism, and the title of the paper was "alpha-ketoglutarate, an endogenous metabolite, stretches lifespan and compressors in aging mice". The content is as follows: Experiments show that AKG can reduce the biological physiological age by 8.5 years on average, and even by 16 years at most. These results are based on the clinically relevant markers of healthspan, which is the first time in the research involving mammals.

After NMN, AKG, an epic anti-aging substance, has become a new anti-aging force.

Image from cell metallurgy, 2020, doi: 10.1016/j.cmet.2020.08.004.

The so-called AKG means α Alpha-Ketoglutarate (AKG), an important metabolic intermediate in the tricarboxylic acid cycle, is a key node connecting carbon-nitrogen metabolism in cells. AKG determines the overall rate of trihydroxy acid cycle. AKG can regulate longevity by affecting mitochondrial function, inhibiting mTOR signal, inhibiting ATP synthase expression and indirectly activating Sirtuins protein.

As early as 2014, AKG attracted people’s attention as a possible anti-aging tonic. At that time, the research report of the British magazine Nature said: "Adding α -Ketoglutaric acid can prolong their life by about 50%. "

Professor Brian Kennedy, a genetic biologist who is the main person in charge of the project, said: "We screened dozens of compounds related to aging, and the last molecule that jumped out was α -Ketoglutaric acid, so I finally decided to carry out further research that is not as good as animals. "

According to the interim data published in the first half of this year, about two-thirds of the subjects showed the effect of reducing life expectancy, with an average life expectancy of 12% and an average incidence of 46%. According to the final experimental data, the subjects fed with AKG scored more than 40% higher in the "weakness" test, which was based on 31 physiological attributes, including hair color, hearing, gait and grip strength.

After NMN, AKG, an epic anti-aging substance, has become a new anti-aging force.

It is worth noting that the life span of female mice in the experiment is 8% to 20% longer than that of the control mice, and if compared with humans, it is equivalent to extending the life span by up to 16 years.

And then professor Brian KennedyAnother heavy experimental result published in Nature further proves the influence of AKG on human anti-aging.

After NMN, AKG, an epic anti-aging substance, has become a new anti-aging force.

In the experiment, Professor Kenney’s team organized 42 middle-aged and elderly people (with an average age of 63 years) to supplement for 7 months.AKG and vitamin compound preparation. Seven months later, the researchers re-measured the physiological indexes of this group of middle-aged and elderly people. The results showed that after 7 months of AKG intervention,The physiological age of this group of middle-aged and elderly people is 8 years younger on average.. At the same time, the participants’ sleep quality and other indicators have also improved significantly.The energy level jumped by about 50%.

Professor Kenney believes that this result confirms his initial guess: "In a sense, the level of AKG will decline with age. So we need to supplement it and let the body return to a younger level. "

At the same time, he also cautiously indicated that AKG needs further experiments to develop in view of the objective problems such as the small number of samples in this experiment.

Unlock the time code and refuse to grow old meekly.

Professor Kenney once said with confidence: "There is no reason why you can’t be interfered when you get old" and "Please don’t meekly accept getting old".

After NMN, AKG, an epic anti-aging substance, has become a new anti-aging force.

There is still a long way to go to study AKG, and how to use it better is the focus of people’s attention. It is reported that AIBORST (Albers Special), a well-known American anti-aging brand, recently announced the news that its first dietary supplement with AKG as the main body, Gene Kangyuan AKG18000, will land in the China market. I believe that in the future, with the deepening of AKG research, a new era that belongs to the health of the whole people and is rooted in anti-aging will soon open.

In the face of Huawei’s new product launch without Mate50 mobile phone, several families are happy and worried.

Since its release three years ago, HarmonyOS has continuously brought new functions and new experiences to consumers, becoming the fastest-growing intelligent terminal operating system in the world. The super terminal allows multiple devices to cooperate and help each other, and the control is simple and convenient. The universal card allows services to flow across terminals conveniently, and the smooth performance makes the devices easier to use, and the privacy protection makes everyone feel more at ease …

At the press conference, HarmonyOS was used as a series, and all products were told together, instead of releasing this and that separately like friends, just because it is called HarmonyOS and everything is based on HarmonyOS.

HarmonyOS is not only a system, but also an intelligent terminal and a super terminal.

The device itself is no longer an island, but interacts and connects different devices through distributed communication technology, and the degree of intelligence is greatly enhanced. Cross-end circulation, small art assistants … Barabara a lot, too rich in functions, I didn’t keep up … Let’s talk about equipment.

The first color inkjet printer equipped with HarmonyOS, which can be pulled at once and super printed. Primary color printing engine, natural color, what you see is what you get. Dual-frequency and dual-antenna, stable connection. Simple operation, free printing, make life more colorful!

The new watch is naturally equipped with HarmonyOS 3.0 system, and the watch is no longer an island device, but has become one of the control terminals in HarmonyOS. Support super linkage, which can efficiently link Huawei mobile phones, Huawei smart screens, Huawei headsets, and other treadmills to upgrade smart life.

Independent call, independent taxi, watch control, not only independent GPS, but also watch navigation, support watch WeChat and super battery life mode. Added ECG ECG analysis. Huawei’s ECG analysis prompt software has obtained the second-class medical device registration certificate of the Drug Administration. Touch the side electrode of the wrist watch with your fingertips to collect ECG signals for 30 seconds, and cooperate with Huawei’s ECG analysis and prompting software to generate ECG reports, prompting sinus rhythm, atrial fibrillation, ventricular premature beats and atrial premature beats in adults.

You can wear hands and feet … more professional motion sensing.

All-round health management, with female physiological cycle function. The original version supported independent GPS, and this one was simply downgraded to the glory watch ES (I didn’t see about independent GPS), which was not good enough.

Then there is the voice interaction designed for the visually impaired, and the AI subtitles designed for the hearing impaired-how to say that God closed a door for the disabled, and Huawei specially opened a window for them. This is called people-oriented science and technology, and it is praised by every enterprise that cares about society.

The performance version uses Snapdragon 888 processor to perform very well on the tablet, at least there is no space limit, and heat dissipation is not a problem; The 11-inch 2.5K large screen made of OLED has better display effect and higher brightness; In terms of design, it is the lightest, thinnest and highest screen ratio in the world, which is described in two words-"flagship"; 16MP in front, 13MP+8MP in rear, four channels and six yang, HarmonyOS 3 system. The standard version is Snapdragon 870 processor, so buy it on demand.

By the way, I got a new color M-Pencil. And a matching tablet keyboard.

As a light and light business book in the MateBook family, there are two color schemes of brocade white and ink blue. Personally, I like brocade white-beautiful notebooks are the same, and white notebooks are unique. Huawei MateBook X Pro is the flagship level in configuration, screen and body. On the basis of the original 90Hz high brush and 3.1K primary color full screen, it is equipped with the follow-up Intel 12th generation processor, which has stronger performance and lower power consumption. In addition, with the blessing of HarmonyOS cross-screen collaboration, the introduction of AI remote operation, innovative gestures and pressure touchpad makes it more like a duck to water in office and other scenes.

The name is already obvious, the new 86-inch smart screen. The big TV doesn’t reflect light, and it adopts AG anti-glare technology to watch movies more clearly. After the addition of HarmonyOS 3 system, the smart screen is tight and perfect in function, and the S86 Pro 98% accounts for 98% of the large screen with 2.7mm ultra-narrow metal frame, showing an unbounded vision; Magnetic AI eye, which can be turned on and off to protect privacy. 3 kinds of suspension methods, suitable for every kind of life.

The high-end earphone product line has also been added. This is the world’s first HWA certified TWS earphone. In official terms, it is "a new leap in the domestic audio industry"-it is in the ear. Huawei FreeBuds Pro 2, which integrates super-sensing acoustic dual units, builds the flagship of Huawei earphone sound quality, and realizes a new experience of super-sensing digital acoustics, so that you can enjoy it and feel the charm of the original sound.

Active noise reduction+wind noise resistance, in a word, looks like a cow X, but as a flagship model, its waterproof performance is slightly lower, and only IP54 is splash-proof.

AITO brand’s first pure electric vehicle-Aito Wenjie M5EV will be officially released in September! Continue AITO brand family design, closed front face and exclusive "warm nebula" color matching to meet the personalized car purchase needs of urban consumers. It is equipped with a HarmonyOS smart cockpit that is often used and has a smooth experience. Pure electric travel is more intelligent.

In a word, it is cheaper than M7 and more expensive than Wuling Hongguang EV.

Many consumers, even friends, still laugh at HarmonyOS 1.0. When HarmonyOS 2.0 came out, they felt ordinary; Now that HarmonyOS 3.0 is released, many people are surprised. If nothing else is said, in terms of interconnection, both the Android ecosystem and the APPLE ecosystem have been left behind by HarmonyOS 3.0. If we say that in this track of the Internet of Everything, friends are still entangled in whether they can accelerate the 10s family car in 100 kilometers, then Huawei has mass-produced 5s super-running. Printers, headphones, cars, smart screens, tablets and notebooks are all connected to the HarmonyOS ecosystem, which makes them full of charm. Throughout the conference, we also saw various fitness equipment such as treadmills, mobile phones, cameras and even various products, from lighting to shading, from smart homes to fresh air, from security to audio and video, which almost covered the "clothing" and "housing" of our daily life.

Different from the ecological circle of friends and businessmen, almost all operations need mobile phones; HarmonyOS items do not leave the mobile phone, but each item can be used without a mobile phone. HarmonyOS super terminal allows multiple devices to cooperate and help each other. Mobile phone is only one of the ecological chains, but it is not the main line. In addition, not all products are made by Huawei (or called Zhizao), and those brands that join Huawei’s ecological circle early and become "Huawei’s intelligent travelers", just like the passengers of the giant ship, are destined to conquer more markets with the warship HarmonyOS.

So does anyone still think HarmonyOS is an Android case?

Top 10 prefecture-level cities with GDP in 2020： Suzhou will ride five cities and exceed one trillion.

　　In addition to municipalities directly under the central government, cities with separate plans and provincial capitals, there are also some ordinary prefecture-level cities with very strong economic strength.

　　According to the statistics of the First Financial Reporter, the top ten ordinary prefecture-level cities with GDP in 2020 are Suzhou, Wuxi, Foshan, Quanzhou, Nantong, Dongguan, Yantai, Changzhou, Xuzhou and Tangshan. Among them, a total of five cities broke through the trillion yuan mark, and Suzhou broke through the 2 trillion yuan mark. In the top ten, Jiangsu Province accounted for half.

　　Table: Top Ten Prefecture-level Cities in GDP

　　Five cities have exceeded one trillion, and Suzhou is far ahead.

　　In 2020, the number of cities with GDP exceeding one trillion reached 23, an increase of 6 over the previous year. Among them, there are five ordinary prefecture-level cities that exceed the trillion yuan mark, an increase of two over the previous year, and the new entrants are Quanzhou and Nantong.

　　Among them, Suzhou, the "leader", is far ahead in prefecture-level cities, and its GDP is 1.6 times that of Wuxi, the second place. It is known as the most cattle prefecture-level city, and many indicators can be described as "invincible" in prefecture-level cities. According to the data of Suzhou Municipal Bureau of Statistics, the GDP in 2020 will reach 2,017.05 billion yuan, an increase of 3.4% over the previous year at comparable prices. This is also the sixth city in China whose GDP has exceeded 2 trillion yuan, and the only ordinary prefecture-level city that has exceeded 2 trillion yuan.

　　It is worth noting that in 2020, the contribution rate of Suzhou’s scientific and technological progress reached 66.5%, and the number of high-tech enterprises declared, recognized, net increased and effective reached a record high. At the end of the year, there were 9,772 effective high-tech enterprises, ranking fifth in the country and leading the new first-tier cities. At the same time, the city’s general public budget revenue reached 230.3 billion yuan, an increase of 3.7% over the previous year, ranking fourth among large and medium-sized cities in China for the first time.

　　Ding Changfa, an associate professor in the Department of Economics of Xiamen University, analyzed the first financial report. Suzhou is backed by Shanghai, and the spillover effect of Shanghai is particularly obvious. Strong scientific and educational resources and modern service industries have promoted the transformation and upgrading of Suzhou, Wuxi and other southern and central Jiangsu regions.

　　On the other hand, several county-level cities under the jurisdiction of Suzhou, such as Kunshan, Zhangjiagang and Changshu, have long been among the top 100 counties in China. Among them, Kunshan has been ranked first in the ranking of the top 100 counties and cities in China for more than ten years, and is known as "the strongest county in China". In 2020, the city’s GDP will be 427.68 billion yuan, and the current price growth rate will be 5.7%; The total industrial output value has historically reached a new level of one trillion yuan; The total retail sales of social consumer goods was 139.81 billion yuan; The actual utilization of foreign capital was US$ 1.05 billion, and the growth rate of 40.3% reached a new high in the past five years.

　　After Suzhou, Wuxi, also from southern Jiangsu, ranked second, and was in the echelon of 1.2 trillion yuan with cities with separate plans and provincial capitals such as Ningbo, Qingdao, Changsha and Zhengzhou. It is worth noting that in 2019, Wuxi’s per capita GDP ranked first among ordinary prefecture-level cities.

　　Foshan ranks third among ordinary prefecture-level cities, and ranks third after Shenzhen and Guangzhou, the first economic province. Foshan is a big industrial city in China, and its industrial output value ranks among the best in the country, with outstanding industrial economic strength in equipment manufacturing, household appliances, ceramic building materials and metal products.

　　Quanzhou and Nantong are the new cities that entered the trillion-dollar mark this year. The data shows that in 2020, Quanzhou’s GDP was 1,015.866 billion yuan, an increase of 2.9%. In the closing year of the Thirteenth Five-Year Plan, Quanzhou’s total economic output exceeded 1 trillion yuan for the first time, ranking first in Fujian for 22 consecutive years.

　　As an ordinary prefecture-level city, Quanzhou can overwhelm Fuzhou, the provincial capital, and Xiamen, a sub-provincial city and a city with separate plans, and become the first city with a GDP of one trillion yuan in Fujian, relying on a solid real economy and private economy. Ding Changfa said that a major feature of Quanzhou’s economic development is that the county economy is very developed, and the county economy has formed a very complete industrial chain. Jinjiang, Shishi, Nan’ an, Anxi and other places under its jurisdiction have outstanding flagship industries.

　　According to the data released by Nantong Municipal Bureau of Statistics, according to preliminary accounting, the city’s GDP for the whole year was 1,003.631 billion yuan, an increase of 4.7% at comparable prices, and the growth rate was 2.4 and 1.0 percentage points higher than that of the whole country and the whole province respectively. The GDP has exceeded one trillion yuan, which indicates that Nantong’s comprehensive strength and production capacity have reached a new level.

　　It is worth noting that in recent years, the net outflow of Nantong population has shown a decreasing trend year by year, which is formed by the combined effect of the decrease of the out-of-town population and the increase of the foreign population year by year. In 2020, the resident population will historically exceed the registered population.

　　Compared with Quanzhou and Nantong, Dongguan, which was expected to exceed one trillion yuan in 2020, was temporarily stranded due to various factors. In 2020, the GDP of Dongguan is 965.019 billion yuan, ranking sixth among ordinary prefecture-level cities.

　　Hu Gang, president of South China Urban Research Association and a professor at Jinan University, said that Dongguan has the highest degree of economic extroversion, and will be greatly impacted by the export-oriented economy in 2020. Affected by the epidemic, a large number of migrant workers found it difficult to return to their posts in the first quarter of 2020, and many orders could not be completed; After April, the export was blocked again. However, with the rebound of orders, according to the current situation, Dongguan’s GDP will stand at the trillion-dollar mark in 2021.

　　Jiangsu, the top ten cities, accounts for five.

　　Judging from the regional distribution of the top ten cities, all of them come from the eastern coastal areas, including three in the northern region, namely Yantai, Xuzhou and Tangshan; There are seven in the southern region.

　　In terms of provinces, Jiangsu, the second largest economic province, has the largest number, and there are five in the top ten, namely Suzhou, Wuxi, Nantong, Changzhou and Xuzhou. These five cities have become attached to the subway at present.

　　Besides Jiangsu, the other five cities are from Guangdong, Fujian, Shandong and Hebei. Among them, two cities in Guangdong are Foshan and Dongguan, ranking third and fourth in Guangdong. Quanzhou ranks first in Fujian for a long time, Yantai ranks third in Shandong, and Tangshan has been pushing Shijiazhuang, the provincial capital, to rank first in Hebei.

　　Judging from the development paths of these 10 cities in recent years, there are great differences. Among them, several prefecture-level cities located in the Yangtze River Delta and Pearl River Delta have gained more spillover from first-tier cities and second-tier leading cities, and in recent years, the transformation and upgrading have shown positive results, such as Suzhou, Dongguan, Wuxi, Nantong, Foshan, Changzhou and other cities.

　　For example, Shenzhen, with a local area of less than 2,000 square kilometers, has become increasingly saturated with land development space, so many industries in Shenzhen have spilled over to the surrounding areas, and Dongguan has benefited the most from its proximity to the moon. At present, an industrial complementary cooperation system of "you have me and I have you" has been formed between Dongguan and Shenzhen.

　　Nantong, from the central Jiangsu area and the north bank of the Yangtze River estuary, adheres to the general idea of "all-round integration into southern Jiangsu, all-round docking with Shanghai, and all-round promotion of high-quality development" to build a strong fulcrum city in the core triangle of the Yangtze River Delta integration. According to local media reports, Ji Jianlin, a professor at the Party School of Nantong Municipal Committee, said that the deep docking with Shanghai is an important driving force and source for Nantong’s GDP to exceed one trillion yuan.

　　Niu Fengrui, a researcher at the Center for Urban Development and Environment Research of China Academy of Social Sciences, analyzed the First Financial Report that the spillovers of energy and radiation from first-tier cities and top-tier cities are closely related, and the closer they are to high-energy cities, the stronger they will receive radiation, so that the high-tech spillovers of core cities will first choose neighboring cities.

　　The elements of modern service industry in first-tier cities and second-tier leading cities have accelerated the transformation and upgrading of surrounding manufacturing cities. However, for some ordinary prefecture-level cities such as Quanzhou and Yantai, which are far away from the three economic circles and the first-tier cities, there are still more ways to go for their transformation and upgrading and structural adjustment.

　　Take Quanzhou, the first economic city in Fujian, as an example. At present, the leading industries in Quanzhou are still light industries such as clothing, shoes and hats. Compared with similar cities, there are fewer high-tech enterprises in Quanzhou, the modern service industry is weak, and there is a bottleneck of insufficient talents in transformation and upgrading. For example, the data shows that in 2020, the number of high-tech enterprises in Quanzhou reached 1037, a net increase of 352 over 2019. However, compared with Dongguan, Suzhou, Wuxi, Foshan and other ordinary prefecture-level cities with large economic aggregates, there is a huge gap.

　　The situation in Yantai is similar. Last year, the total number of high-tech enterprises in Yantai reached 1,120, an increase of 36% over the previous year, ranking third in the province in terms of new number and total number respectively. However, compared with similar cities in the Yangtze River Delta and the Pearl River Delta, the gap is far away.

　　For such cities, it may be necessary to strengthen their internal strength, improve the business environment, accelerate the construction of central cities, accelerate the development of modern service industries, and accelerate the upgrading and development of industries on the basis of existing manufacturing industries.

　　Niu Fengrui said that these cities need to have their own special orientation in the industrial structure and direction. They don’t have to follow the fashion and trends, but they should choose industrial sectors with comparative advantages according to their own resource endowments, regional characteristics and original industrial base, and focus on development. "In the geographical division of labor, we must have our own positioning, depending on whether there is a comparative advantage and whether there is a relatively lower production cost, which is the key to future development."

Parents should be careful! This ＂online celebrity balloon＂ will burn through the wool cap in an instant when it explodes.

　　CCTV News:At present, a "online celebrity balloon", named Bobo Ball, is selling well on the street, which is highly sought after by children and couples. And just recently, this "online celebrity balloon" exploded:

　　When a man was smoking, he accidentally spilled sparks on the balloons, and all six balloons exploded.Four people were burned to varying degrees, and the most serious was second-degree burns.

　　Balloon exploded and 4 people were burned.

　　The structure of luminous balloon is very simple, and its components include a transparent balloon, a string of colorful LED strip and two batteries. Although "beautiful in appearance", there are certain security risks.

　　A few days ago, four people were injured by online celebrity balloon, and two of them were badly burned. The 26-year-old Mr. Zhao (changed his surname) still has a lingering fear when he recalls that scene.

　　He said that after a group of four people had finished their meal that night, they saw someone selling such balloons on the road. They thought it was quite good and bought five or six balloons. Then four people got into a taxi with balloons. At that time, a brother lit a cigarette and touched the balloon, which suddenly exploded.

　　Mr. Zhao: At that time, the power was too great! I’m confused!

　　According to the doctor, when these people arrived, they all had different degrees of burns, two were slightly injured and two were seriously injured. Mr. Zhao is the most seriously injured, and the initial diagnosis,His face and limbs were burned to the second degree.The specific injury needs further diagnosis; There is also a woman with burns on her face.

　　Network hot-selling filling gas is unknown

　　The reporter found in some online shopping platforms that this kind of luminous balloon, also called "bobble ball", is also very popular in online sales, and many shops have sold tens of thousands of pieces. The price is very cheap, and the ordinary model includes a wave ball, a LED strip and three batteries, and the price is 5-8 yuan.

　　As for what gas is filled in the balloon, vendors have different opinions, some say it is hydrogen, and some say it is helium. There are also many shops that directly indicate that it is safe to use air instead of helium.

　　According to the investigation, a 13-liter helium tank needs 72 yuan, which can fill 15-17 balloons. On average, each balloon costs about 5 yuan.And if filled with hydrogen, the average cost of each balloon is only a few hairs.

　　According to the doctor, there have been mass accidents of hydrogen balloon burning and explosion in the past, butNow, for the sake of safety, generally speaking, balloons are filled with helium.Helium is an inert gas, which is relatively safe.However, it is not excluded that some vendors use hydrogen instead of helium in order to save costs.

　　Hydrogen is flammable and explosive, andHydrogen balloons and helium balloons are difficult to judge from the appearance.Judging from the description of the explosion power of this balloon by the injured, it is likely that the balloon they bought was pretending to be helium with hydrogen.

　　Has been issued a consumer warning by the European Union.

　　As early as March this year, the European Commission’s non-food rapid warning system (RAPEX) issued a consumer warning to balloon toys with LED lights of unknown brands made in China.

　　The reason for this warning is expressed by the EU as follows:

　　“The product is at risk of chemical, asphyxiation and injury.Because the balloon is easy to burst, releasing small parts including button cell, LED lights and sharp nails, and may be swallowed by children, causing injury or suffocation to organs including esophagus and stomach;The product does not meet the requirements of toy safety directive and related European standard EN 62115."

　　Measured the power of "online celebrity Balloon"

　　So, how dangerous is this online celebrity balloon? The reporter went to the Peking University Squadron of Fengtai District Public Security Fire Brigade for an experiment.

　　Experiment 1 Burning with an open flame gives off a pungent smell.

　　First, firemen simulate what might happen when the bobo ball meets an open flame.

　　The reporter saw thatThe balloon was ignited at the moment when it touched the open flame of the lighter.The burnt drips on the table continue to burn and catch fire, and turn into black glue with obvious pungent smell.

　　“The burning of this substance will produce toxic gas, which will cause burns to people’s respiratory tract, and once the dripping directly touches the skin, it will cause burns to the skin.Fang Chen, the squadron leader of Yuquanying Fire Squadron in Fengtai District, said.

　　Experiment 2 Drops burn through the hat

　　 The reporter put the prepared winter children’s hat under the balloon to simulate the situation that the melt accidentally dripped on the clothes when the balloon was ignited by fire.

　　The reporter saw thatDrops dripped on the wool hat, and the surface quickly burned and burned through.The fiber on the surface of the hat has been burnt black, and on the other hand, the inside of the hat has been burnt through by black glue.

　　Fang Chen said that this situation is very dangerous and will cause serious burns to the skin on the head surface.

　　The fire department reminds:

　　△ When buying such balloons, be careful not to choose those containing hydrogen, helium and other combustible gases;

　　△ Secondly, carefully check whether there are cracks on the surface of the balloon and the connection point, and you must choose a regular manufacturer to buy it;

　　△ When playing with balloons, try to stay away from fire sources and sharp objects to prevent dangerous situations such as burning and explosion.

Why is it difficult to protect consumers’ rights and interests？

A few days ago, a car blogger posted that his friend bought an AITO Wenjie M5, and due to the epidemic prevention and control, licensing in special areas and the continuous high temperature, he informed the store to pick up the car later. But not long after, AITO issued her an order invalidation notice, saying that the order was invalid and the deposit would not be refunded.

This notification letter pointed out that it has been more than 10 working days since the consumer was notified to pick up the car, and the remaining car purchase money has not been received so far. According to the AITO Car Subscription Agreement, it is regarded as having given up buying a car.

In this regard, the consumer believes that he has not signed this agreement and has not agreed on the time of car purchase. Interface News tried to contact the consumer and got no response.

The relevant person in charge of Huawei’s automobile brand told the interface news that after discovering the complaint, the user center tried to communicate with the consumer, but it was not able to contact him yet.

"Our new delivery specialist didn’t hand over the work well and didn’t understand the previous communication situation. He directly sent an order invalidation notice, which was not in accordance with the standard process." The person in charge said that the consumer’s order was not cancelled and the deposit was not confiscated.

As a high-end new energy brand jointly built by Cyrus and Huawei, AITO currently sells models of Wujie M5 and Wujie M7, among which the first pure electric model, Wujie M5 EV, was released on September 6th, and the reservation was started. On the first day of listing, the order volume of M5 EV has exceeded 30,000.

However, with the increase of orders, the disputes between AITO and consumers began to increase. The interface news noticed that in the relevant complaint platform, most of AITO’s complaints were linked to the deposit, and focused on the non-refundable deposit and the sales concealment to induce the order.

A consumer complained that when he paid the deposit, the sales did not clearly tell whether the deposit could be refunded and the time limit for withdrawal; Another consumer told the interface news that he applied for a refund during the hesitation period of the deposit, but the refund process took a long time and waited for nearly three months. On the complaint platform, many consumers have been waiting for a refund for more than two months.

Interface News called a Huawei experience store as a consumer, and the car sales consultant of the store told Interface News that you can pay a deposit through online channels such as Huawei Mall to buy a brand car. The sales reminder, within 72 hours without confirming the lock order, the deposit can be refunded.

"Now, the M5 pure electric version has just been listed, and there is still a small order stage. You can pay 1000 yuan’s intention to reserve the rights and interests first, and the small deposit can be refunded at any time."

When asked about the deposit contract, the seller said that an electronic version of the contract would be issued when the deposit was paid. However, it was not until the final payment that the reporter noticed a line of small-print reminders, asking for the approval of the AITO Automobile Subscription Agreement and the AITO Automobile Privacy Policy. These two agreements will not pop up automatically, and consumers need to read and understand them themselves.

According to "AITO Automobile Subscription Agreement", 72 hours after the subscription deposit is paid belongs to the hesitation period. During the hesitation period, the subscription agreement can be terminated by unilateral notice. When the notice is delivered, all the subscription deposit paid will be refunded. Beyond the hesitation period, it is deemed that the unilateral termination right has not been exercised or waived, and the subscription deposit will not be refunded.

The above agreement also emphasizes the terms of the offline car purchase contract. The agreement requires consumers to go to the designated user center to sign the car purchase contract and pay the remaining car purchase price within 10 working days after receiving the notice. If it is not signed within the time limit, AITO has the right to decide to cancel the order and deduct the deposit paid.

Lawyer Gu Pan of Beijing Dacheng (Xi ‘an) Law Firm said in an interview with Interface News that the signed subscription agreement is a formal sales contract and is binding on both parties.

During the period of repentance agreed in the contract, the consumer notifies the merchant to return the deposit without a lock, and the merchant shall return the deposit according to the contract, otherwise the merchant will constitute a breach of contract; On the other hand, if the consumer fails to pay the final payment within the time limit stipulated in the contract, he will also be liable for breach of contract. Therefore, when buying bulk consumer goods such as automobiles, consumers should carefully browse the contract and understand the specific terms.

"If the seller makes false propaganda and misleading, causing misunderstanding among consumers, then the misled party can demand to terminate the contract and return the paid fees through litigation."

Gu Pan stressed that in practice, it will be more difficult for consumers to prove that they have not been informed or misled in advance, so it is necessary to pay attention to fixed evidence. When returning the deposit within the prescribed time limit, you should also remember to keep the written notice evidence to safeguard your rights and interests.

Zhang Xiang, a special expert of China Bolian think tank, told the interface news that the current car reservation system started from Tesla, and new forces have started booking processes such as small booking and big booking. Car owners who order in advance can enjoy more rights and pick up the car first.

"Most of the new car-making forces have a policy of free refund of the deposit. Only when they are about to go bankrupt or have no cash on their accounts will they not get the deposit back."

Zhang Xiang believes that it takes a long time for the brand to refund the deposit. On the one hand, the process cycle of refunding the deposit is really long, on the other hand, it also reflects Huawei’s lack of attention to consumer rights. "The contract does not clearly state the time requirement for refund, and the seller will naturally delay."
