Country Garden finally "showdown"?

In the past year, the domestic real estate industry experienced an unheard-of thunderstorm. From leading real estate enterprises such as Evergrande and Sunac to small and medium-sized Taihe and Huaxia Happiness, many real estate enterprises fell into debt and broken capital chains because of their "three highs" (high leverage, high debt and high risk) business model.

Even Country Garden, once known as "the first real estate enterprise in the universe", has ushered in a thunderstorm moment. In fact, this matter has long been a clue.

First, in mid-October last year, Country Garden, which couldn’t pay interest on time due to a US dollar debt, declared a formal breach of contract, and the group fell into a liquidity crisis. After several months of advance notice, Country Garden recently announced on the Hong Kong Stock Exchange that its creditors filed a liquidation petition with the court, involving unpaid term loans and interest of up to HK$ 1.6 billion.

In addition, according to public information, as of the end of last year, Country Garden’s total liabilities were about 1.36 trillion, which was second only to Evergrande’s 2.38 trillion in the liabilities of a number of housing enterprises.

Affected by this, Country Garden shares became "fairy shares", and the price per share fell below $1, which directly led to its market value falling again and again. However, in sharp contrast to the plummeting stock price, many Country Garden executives quickly cleared their shares, including Yang’s father and daughter, and exposed the news that "the founder’s family paid dividends of 42 billion yuan", which made people feel sorry: after all, they followed Evergrande’s footsteps!

Yang Guoqiang, who came from a peasant family, believed that "land is wealth" at the beginning of his business, and he understood that the land profit in the county town has a lot of room for operation. Therefore, the buildings in Country Garden are generally located in remote suburbs or even at the foot of the mountain in the hinterland.

Relying on the mode of "rural encircling the city", Country Garden frantically borrowed money to encircle the land. According to its financial report, Country Garden successfully went public in 2007 with a land reserve of 19 million square meters, and Yang Guoqiang’s second daughter Yang Huiyan’s net worth was as high as 121.15 billion, surpassing Wang, Xu, Ma and other bosses to become the richest man in China, and was the richest new generation.

However, Country Garden can become the "first real estate enterprise in the universe", and it has to start from 2015. At that time, it was at the time when the monetization of sheds was implemented in China, and the monetary income of sheds in third-and fourth-tier cities was changed, which made Country Garden earn a lot of money and further opened up crazy expansion.

In 2006, Country Garden’s total debt was only 13.836 billion yuan, which soared to 933.1 billion yuan in 2017, and then increased to 1,758.8 billion yuan in 2017, reaching a historical commanding height. In just 14 years, the total debt has more than 127 times!

Borrowed so much money, where did it go? Naturally, it is enclosure and dividend.

As a well-known "king of enclosure" in the domestic real estate industry, Country Garden’s land reserve area once increased to 282 million square meters. The more debt, the harder the dividend. As the actual controller, the Yang family has taken 42 billion dividends since its listing in 2007, and the family members can get at least 15 million annual salary. Although Yang Huiyan once donated 20% of his equity to Guoqiang Public Welfare Foundation, this move was also criticized as "left-handed and right-handed".

In contrast, another real estate tycoon, Hong Kong Fuli, is much more stable. Not only was he very cautious in land acquisition, but he also sensed the tightening of domestic real estate dividends in advance, decisively cashed out, and transferred a large amount of money into the territory of Huangpi Medicine and "Jinzhiyin".

In 2021, Hutchison Pharmaceuticals successfully rang the bell on the Hong Kong Stock Exchange, and the market value soared to 70 billion that day, helping the Li family’s commercial map to add a solid tile. The above-mentioned biotechnology has been confirmed by Harvard, Qingbei and other scientific research institutions, which can maintain the vitality of the organism, extend the life span of organisms by 30%, and play a positive intervention role in the process of aging.

As early as 2017, Hong Kong Fuli began to use the predecessor of "Golden Cause". At that time, the cost of taking it was as high as 1.28 million times. Perhaps it was his persistence that paid off. After the photo of his 96th birthday party came out, netizens paid attention to it: "I am in good health and look more like a 69-year-old."

With the support of capital and scientific research, only Hong Kong Fuli, Pan Paopao and others enjoyed the scientific and technological dividend a few years ago. Now, the iteration of the same name "Jin Zhi Yin" has landed in Beijing-East and Tian-Cat, helping millions of Chinese people to improve their quality of life, but Yang’s father and daughter failed to catch up with this bus.

Looking back, it’s self-inflicted that Country Garden will "storm". A few months ago, Evergrande was exposed to the suspension of trading, but Country Garden, as the same style of doing things, did not realize the truth of stopping in time, and still invested heavily in overseas assets. Is it because these years have been too smooth and smooth, and all business vigilance and reflective ability have been discarded?

However, it is worth noting that, although like Evergrande, it likes crazy enclosure and huge dividends, Country Garden is at least desirable in its attitude. For example, Yang’s father and daughter have sold their private assets several times and paid their debts voluntarily.

Although compared with the trillion-dollar debt, the money can only alleviate the "urgent need", at least it is expressed. I hope Country Garden can work hard to hold on, otherwise its "leveling" power will be no less than Evergrande’s.

At the group management meeting in April, the management of Country Garden put forward the working policy of "one floor, one guarantee and delivery" in view of the current main tasks. In addition, we should seize the opportunity and strive for more projects to enter the "white list".

On April 7, Country Garden issued an announcement to disclose the progress of its overseas debt restructuring and the appointment of legal counsel. After Country Garden announced on October 10, 2023 that it was seeking a comprehensive solution, it cooperated with creditors and main consultants and made positive progress in overseas debt restructuring. The company has set up a coordination committee representing bank creditors and a project team representing bondholders. At present, the two sides are discussing the information sharing mechanism and fee arrangement.

Country Garden is conducting feedback on due diligence issues, and referring to international best practice guidelines, including the Second Edition Statement of Principles on Global Experiences of Multi-creditors in Solving Debt Problems without Court Procedures and the Code for Handling Financial Difficulties of Hong Kong Enterprises.

Country Garden said that the main financial consultants are continuing to advance the preparation of the cash flow model. In addition, in order to provide a common information platform for creditors, the company has hired De Anhua to analyze the independent debt recovery rate of the group on the premise of being cautious to creditors, so as to help creditors make better rational judgments when examining the company’s operation in the future.

It continued that Country Garden plans to establish a regular communication mechanism with overseas creditors and update the restructuring process to overseas investors in a timely manner. The company reiterates that we are determined to promote a comprehensive solution that can ensure the long-term development of the Group, safeguard the rights and interests of all stakeholders and ensure fair treatment of all creditors.

Country Garden also said that the company has appointed Nianlida Law Firm as the main legal adviser for overseas debt restructuring. Nianlida Law Firm will work with the company and its main consultants to ensure a transparent and constructive dialogue between the company and overseas creditors.

At the end of February, Country Garden announced on the Hong Kong Stock Exchange that the company was informed of the liquidation petition filed by Ever Credit Limited to the High Court of the Hong Kong Special Administrative Region on February 27, 2024, concerning the unpaid term loan with a principal of about HK$ 1.6 billion between the petitioner (lender) and the company (borrower) and accrued interest. The company will strongly oppose the petition.

On March 28th, Country Garden announced that it would delay the publication of the 2023 performance report. The explanation given by the company for delaying the publication of financial reports is that the industry continues to fluctuate and the business environment faced by the company is becoming increasingly complex. It needs to collect more information to make appropriate accounting estimates and judgments. Affected by this, Country Garden shares have been suspended since April 2.

In 2024, the word "trade-in" has received unprecedented attention.

At this year’s National People’s Congress, the government work report stated this year’s tasks: stabilize and expand traditional consumption, encourage and promote the trade-in of consumer goods, and boost the mass consumption of intelligent networked new energy vehicles and electronic products.

This is the third time recently that the Central Committee has mentioned trade-in at a heavy meeting.

The reporter interviewed relevant departments, enterprises and experts in Chongqing, all of whom were eagerly awaiting this round of trade-in, hoping that the national policy would be more powerful and targeted.

But this time it’s obviously different. First, the scope of this trade-in is wider. As can be seen from the contents of the central meeting, it covers household appliances, automobiles and industrial and agricultural equipment updates. Second, the supporting role of current consumption in economic development has become more prominent, which means that more funds and resources will be invested in this round of trade-in. According to the data of the Ministry of Commerce, the contribution rate of consumption to economic growth reached 82.5% in 2023, while the average annual contribution rate of final consumption expenditure to economic growth in China in the past 10 years was 50.4%. It is not difficult to see behind the digital changes that this round of trade-in of consumer goods will be expected to be higher. Third, related consumer goods have entered a window period of upgrading. Wang Wentao, Minister of Commerce, introduced at the economic theme press conference held at the Second Session of the 14th National People’s Congress that there are more than 16 million passenger cars in use in China, of which more than 7 million are over 15 years old. On average, about 270 million household appliances exceed the safe service life every year. Wang Wentao judged that the potential renewal demand of consumer goods has entered a concentrated release period. According to the estimation of Pacific Securities Research Report, according to the average selling price of new cars of 170,000 yuan, the replacement of old vehicles is expected to bring about 1.3 trillion yuan of consumption scale increase in 2024.

Lang Xuehong, Deputy Secretary-General of china automobile dealers association, said in an interview with the media that by the end of 2023, there were about 340 million cars in China, but only 20 million new energy vehicles, accounting for only about 6% of the total number of cars. The replacement cycle of traditional fuel vehicles is about 6 to 8 years, and that of new energy vehicles is about 3 to 5 years. "From the perspective of the whole society, 40% of the increase in new car consumption this year will come from trade-in." Combined with the consumption of about 25 million new cars in China last year, Lang Xuehong judged that the market size of trade-in was about 10 million.

And the scale of equipment renewal is even larger. At the economic theme press conference of the Second Session of the 14th National People’s Congress, Zheng Shanjie, director of the National Development and Reform Commission, said that recently, the National Development and Reform Commission, together with relevant departments, studied and formulated the Action Plan for Promoting Large-scale Equipment Renewal and Trade-in of Consumer Goods, focusing on the implementation of the "four major actions" of equipment renewal, trade-in of consumer goods, recycling and standard improvement. Taking equipment renewal as an example, the focus will be on seven fields: industry, agriculture, construction, transportation, education, cultural tourism and medical care. With the deepening of high-quality development, the demand for equipment renewal will continue to expand, and it is estimated that it will be a huge market with an annual scale of more than 5 trillion yuan.

Mo Xin, vice president of Suzhou Institute of Environmental Innovation in Tsinghua, once participated in the research and formulation of the "trade-in" policy for automobiles and household appliances in 2009. He said that the new round of large-scale equipment renewal and trade-in of consumer goods are greatly different from the past in terms of implementation areas and subsidy standards, and are expected to be broader and higher.

The reporter learned from the Municipal Commission of Commerce that the 2024 "Aishang Chongqing" green smart home appliances promotion campaign to enter towns, streets and communities was launched on the 8th. Various home appliance enterprises will take home appliances to the countryside, trade-in subsidies, full reduction and discount, etc., and carry out various forms of green smart home appliances trade-in to benefit the people. Enterprises participating in the activities will give consumers who meet the scope of trade-in subsidies a maximum subsidy of 10%, and consumers will write off subsidies or deduct the actual price according to the corresponding standards when paying and settling accounts.

For example, Chongbai Trading Co., Ltd. will organize its 41 stores to carry out the promotion activities of "315 billion yuan subsidy" to benefit the people. Suning carried out activities such as trade-in and high subsidy of 10%; JD.COM will carry out the 315 Home Appliances Life Festival, and trade in the old for the new to make up for the 1000 yuan and other promotional activities; Midea Electric has carried out activities such as trade-in of all its categories and subsidizing 1000 yuan.

The "Smart Home Dishwasher Festival" was also launched on the same day. Citizens can enjoy the subsidy of the Supreme 1000 yuan Association when buying dishwashers, and can recycle old household appliances for free, and enjoy the recycling subsidy of the Supreme 300 yuan.

On March 9th, Chongqing Custom Home Furnishing Association and Chongqing Household Electrical Appliances Service Federation will organize more than 100 brands of various types to hold "315" home industry promotion activities at the main venue of Guanyinqiao Business Circle, launch "home trade-in start-up activities, and launch welfare packages such as full subsidy coupons and discount for old goods evaluation". According to reports, the Municipal Commission of Commerce will provide special funds to support the "Aishang Chongqing" Green Home (Spring) Huimin Expo, which started on March 7, and support key enterprises to trade in old smart home appliances.

Liu Yi, vice chairman and president of Chongqing Akita Gear Co., Ltd., told the reporter, "We are also waiting for this policy to come out. It can be said that we have been waiting for a long time." Liu Yi said that Akita Gear spends more than 100 million yuan on equipment upgrading every year, mainly for technical transformation and expansion of production capacity, and both domestic and foreign equipment are being purchased. In 2023, Akita Gear spent 160 million yuan to update high-end motorcycle gear processing equipment and new energy vehicle gear processing equipment. Liu Yi believes that the demand for equipment renewal in Chongqing’s manufacturing industry is considerable, and the new round of policies will accelerate the overall upgrading of Chongqing’s manufacturing industry.

The reporter then interviewed Yang Qiang, the equipment supervisor of the assembly workshop of Changan Automobile Liangjiang Factory. He told reporters that with the explosion of sales of Changan Automobile, there are three kinds of equipment to be upgraded in this year’s workshop: one is adaptive cruise and panoramic image calibration equipment, the other is initialization and ECU comprehensive electrical inspection equipment, and the third is antifreeze filling machine, all of which are used for the manufacture of intelligent networked new energy vehicles.

Chen Jiawei, head of marketing planning of Chongbai Electric Strategy Department, told the reporter, "We are very much looking forward to the introduction of this trade-in policy. Now our sales platform and manufacturers are jointly doing trade-in. It is not enough to rely on our strength. The country and the government will pull it together and the strength will be even greater. " Chen Jiawei said that Chongbai Electric has paid more attention to the stock market and put it on the old-for-new, and is very much looking forward to this policy. "Not only us, but almost all electrical appliance sales platforms, Suning and JD.COM, have great expectations for this policy, hoping to set off a wave of trends. Judging from our exchanges with electrical appliance manufacturers, regardless of Haier, Midea, Gree and Changhong, they are vigorously promoting trade-in this year, which is their focus this year. " Chen Jiawei believes that now everyone has paid more attention to health. From the sales situation, green smart home appliances are now attracting more attention from consumers, such as fresh air conditioners, dishwashers and dryers in air conditioners, which bring great convenience to life.

Hu Yangji said that in 2023, Chongqing Zhongtian Electronic Waste Treatment Co., Ltd. and Chongqing Zhongjia Environmental Protection Engineering Co., Ltd., the two largest recycling enterprises of old household appliances in Chongqing, recycled 2.32 million sets of old electrical appliances. From this, he speculated that the current actual renewal in Chongqing is 4 million sets per year. If we calculate according to the life cycle of general household appliances of 8-10 years, this round of old-for-new trade-in may bring 10 million sets of replacement to Chongqing market every year.

Hu Yangji believes that last year, the municipal government invested 10 million yuan in financial subsidies, which were used up in a few days, thus boosting sales by more than 400% year-on-year. "This round of central policies has not yet come out, but we are looking forward to it. The activities organized at the government level have stronger credibility and better results than those organized by the merchants themselves. " Hu Yangji hopes that compared with last year’s subsidy of 200 million yuan in Jiangsu and 100 million yuan in Shanghai, from the perspective of Chongqing’s market size, it should at least catch up with Shanghai’s subsidy level and reach 100 million yuan.

Mo Yuanming, a researcher at the chongqing technology and business university Chengdu-Chongqing Shuangcheng Economic Circle Collaborative Development Center, believes that in recent years, both the Central Financial and Economic Committee meeting and the the State Council executive meeting have emphasized the trade-in of old products and accelerated the upgrading of products, resulting in the scale effect of upgrading. This government work report proposes to encourage and promote the trade-in of consumer goods and boost the mass consumption of intelligent networked new energy vehicles and electronic products, which is in line with the spirit of the above meeting. This series of policy measures shows that "trade-in" has become the key measure to promote the steady growth of consumption this year.

On the other hand, boosting consumption needs intelligent networking, new energy vehicles, electronic products and other large-scale consumption to drive. This means that mass consumption of intelligent networked new energy vehicles and electronic products is becoming an important thrust to stimulate consumption and expand domestic demand, and also an important engine to stimulate economic growth.

　　Is it easy to lose weight when frozen? Children with severe heating radiation are prone to leukemia? Exposing the ankle leads to a clever bag?

　　Just after first frost, a wave of cold air hit again. Some "precautions" about winter have also spread. For example, we often hear some old experiences, such as "protecting your head and preventing colds"; Cold can activate brown fat, so wearing less in winter is easy to lose weight; A WeChat article said that heating radiation should be paid attention to in winter, which may lead to leukemia. There is also an article saying that wearing ankle-length pants in winter or getting ovarian chocolate cyst … … Are these rumors really correct?

　　Myth 1: Cold can activate brown fat. Wearing less is easy to lose weight.

　　When the weather is cold, there is less exercise, and it seems more difficult to lose weight. Recently, an article said that the researchers did experiments on mice. After putting obese mice in an environment of 5 degrees Celsius for a week, they lost an average weight of 14%. So there are rumors that cold can make people thin, right?

　　"This statement is not scientific." Ma Jie, director of the Center for Prevention of Diseases of Sichuan Second Hospital of Traditional Chinese Medicine, said that under the stimulation of cold, human beings will use two ways to generate heat quickly to maintain their body temperature. One is shivering to produce heat, which is commonly known as "shaking", which provides heat through the contraction of skeletal muscle. The other is non-shivering thermogenesis, also known as metabolic thermogenesis, which is mainly accomplished by lipid decomposition and oxidation in brown adipose tissue.

　　"Although brown fat has the effect of burning fat, it only exists in a large number of babies or small mammals, such as mice. In adults, only a small amount of brown fat remains, mainly in the neck. Therefore, it is unscientific for adults to lose weight by stimulating brown fat with cold. " Ma Jie said.

　　Wang Chunxiang, director of the Nutrition Department of Zhongda Hospital affiliated to Southeast University, said that although it is called "fat", the function of brown fat is more like muscle. It is responsible for decomposing white fat that causes obesity, and converting glucose and white fat into carbon dioxide, water and energy, without storing calories. Brown fat has a high thermal efficiency. A small piece of brown fat can burn a lot of calories, and even white fat stored in other parts of the body can be used as its "fuel".

　　"But brown fat is rarely distributed in the adult body." Wang Chunxiang said, "For adults, brown fat only exists on both sides of the neck, on the upper back, around the clavicle and spine, and around the great blood vessels." In a normal adult’s body, there is about 60 grams of brown fat, and through CT and other imaging comparisons, the distribution of brown fat in obese people is less than that in thin people, and the distribution of brown fat in men is less than that in young women.

　　Myth 2: Severe heating radiation can lead to childhood leukemia.

　　Heating can be said to be the standard in northern winter. Recently, a WeChat article said that severe heating radiation may cause children to suffer from leukemia. Is this statement correct?

　　Ethan, director of hematology department of the Ninth Hospital of Xi ‘an, said: "I have been a doctor for more than 20 years, and I have never met or heard that floor heating causes children to suffer from leukemia in outpatient clinics and academic conferences. At present, the pathogenesis of childhood leukemia is generally recognized as physical factors, chemicals, ionizing radiation, genetic factors and so on. Among them, ionizing radiation includes nuclear radiation, X-rays, etc. It has been medically confirmed that it can cause bone marrow suppression, cause gene mutation, and lead to leukemia, but I have never heard of the statement that floor heating causes leukemia. "

　　Li Jieping, deputy chief physician of the Department of Hematology, Changsha Central Hospital, said that the exact cause of leukemia has not yet been fully clarified. Many factors are thought to be related to the onset of leukemia.

　　"Virus may be the main factor. The leukemia effect of RNA virus on animals such as mice, cats, chickens and cows has been affirmed. Most leukemia caused by this kind of virus belongs to T cell type. The second factor is genetic factors. People with chromosomal aberrations have a higher incidence of leukemia than normal people, as well as congenital aplastic anemia, and the probability of leukemia is much higher. " Li Jieping said that in addition, radiation and radiation are also the main factors. All kinds of ionizing radiation can cause human leukemia. The occurrence of leukemia depends on the dose absorbed by the human body. The whole body or part of the body can be induced by moderate or large doses of radiation. It is still uncertain whether low doses of radiation can cause leukemia.

　　"Chemical poisons or drugs and other factors can also induce leukemia. Benzene and its derivatives, chloramphenicol, phenylbutazone, ethyldimorpholine, alkylating agents, cytotoxic drugs, etc. can induce leukemia, such as breast cancer, ovarian cancer and lung cancer after chemotherapy. It is also prone to secondary leukemia. In recent years, there have been many reports that indoor decoration and furniture and toy pollution are a major cause of the increase in the incidence of leukemia among urban children. " Li Jieping said.

　　Myth 3: Exposing your ankles and getting cold easily leads to chocolate cysts.

　　Exposing ankles has become a feature of young people’s dressing. Recently, an article said, please put down your trouser legs! A 16-year-old girl, for the sake of beauty, has been wearing ankle-length pants in winter, but she got ovarian chocolate cyst.

　　However, there is no direct evidence that there is a causal link between ankle exposure and chocolate cyst. Xiangyang, chief physician of Obstetrics and Gynecology Department of Peking Union Medical College Hospital, said that ovarian chocolate cyst, also known as ovarian endometriosis cyst, is a pathological change of endometriosis.

　　Under normal circumstances, the endometrium grows in the uterine cavity and falls off once a month under the influence of female hormones in the body, forming menstruation. If the fragments of endometrium shed during menstrual period enter the pelvic cavity through the fallopian tube with menstrual blood countercurrent and are planted on the surface of the ovary or other parts of the pelvic cavity, ectopic endometrium is also affected by sex hormones, and it falls off and bleeds repeatedly with menstrual cycle. For example, if the lesion occurs on the ovary, there will be local bleeding during each menstrual period, which will enlarge the ovary and form a cyst containing old hematocele, that is, "ovarian chocolate cyst".

　　"Because the etiology is unclear, its histology is complicated and cannot be completely prevented. According to the possible etiology and epidemiological results, prevention can be carried out from the following aspects: preventing menstrual blood reflux; Drug contraception; Prevent iatrogenic ectopic endometrial implantation. " Xiangyang said.

　　Zhou Wei, an attending physician of obstetrics and gynecology in Xiangtan Maternal and Child Health Hospital, also said that the cause of ovarian chocolate cyst is not clear, but it is closely related to intrauterine surgery, which is mainly induced abortion. Therefore, the implementation of contraceptive measures and the elimination of induced abortion are helpful to prevent the occurrence of ovarian chocolate cysts.

　　Myth 4: It is easy to catch a cold without wearing a hat at most.

　　In winter, we often hear some old experiences, such as "protecting your head against colds". It is rumored that in winter, your head loses the most heat, and if you go out without a hat, you will obviously get colds and other diseases. Is this true?

　　"For adults, there is no necessary connection between wearing a hat and catching a cold. Wearing a hat has two functions, one is to prevent the head from catching cold, and the other is to prevent the sun from drying, which is not necessarily related to colds. " Zhang Xuan, the attending physician of the Affiliated Hospital of Zunyi Medical College, said that for children, the baby’s physique will not be affected by wearing a hat or not.

　　According to a survey made by American Pediatrician magazine, about 40%— 50% parents believe that low temperature will make their children catch a cold. However, according to the American Academy of Pediatrics, colds are common in cold weather because children will stay indoors more and have closer contact with other students at that time, which provides a more convenient channel for the spread of the virus.

　　The saying that "the head has more heat dissipation" can be traced back to the 1850s. The U.S. Army decided to conduct several tests in extremely cold conditions and then measure the heat lost from the body. The soldiers wore the latest polar survival equipment all over, but they didn’t wear hats. Later, the experiment found that the head did lose a considerable part of the body heat, but in this case of being fully armed and not wearing a hat, of course, the human body must first lose most of the heat through the head. So American Army scientists concluded that 40% of the human body & mdash; 45% of the heat is lost through the head.

　　However, according to an article published in the British Medical Journal, researchers from the Health Policy Center of Indiana University said, "If ‘ The head loses the most heat ’ The statement is really correct, then a person who goes out without a hat will obviously be as cold as a person who goes out without trousers, but we all know that this is obviously not the case. "

October 30 th news, last week’s Xiaomi 澎湃 OS andXiaomi 14 At the launch of a series of new products, Lei Jun announced the launch of one. For 256GBXiaomi 14 Pro, users can get an extra 8GB of space, and for 512GB of Xiaomi 14 and Xiaomi 14 Pro, users can get an extra 16GB of space.

Today, Zhang Guoquan, director of Xiaomi’s mobile phone system software department, interpreted this function, saying that the "UltraSpace storage expansion" function will not cause life risk to UFS at all.

In addition, Xiaomi has contributed the standard to the UFS Association. In order to respect originality, Xiaomi asked chip manufacturers to do a little time protection.

The complete contents of IT House are as follows:

With regard to the storage and expansion function of Xiaomi 14 conference, I have read your feedback these days, and I feel it is necessary to talk about the ins and outs of this function. The text is very long, and students who are not interested in technology can only look at the questions and the answers in the first paragraph.

Why do you want to do this function?

Speaking shamefully, in the past few years, MIUI has been burdened with the nickname of "bloated", and has been vigorously rectifying in the past two years. From last year’s razor plan to this year’s storage expansion, it is a line of succession, and it is necessary to bid farewell to bloated completely.

In Razor Plan 1.0, except for some basic functions, other system applications can be uninstalled. In Razor Plan 2.0, the system firmware should be minimized, and the storage capacity should be expanded to ensure the maximum space available to users.

Ultra-thin Xiaomi 澎湃 OS is not only extremely brisk, but also saves a lot of space. Plus 8GB of hardware expansion, compared with the flagship of Friends, it can get up to nearly 20GB of extra space. In addition, the file deduplication and dynamic compression functions in the OS also improve the storage efficiency, which is not only large, but also more "durable". Taken together, after long-term use, it can store more than 30 or even 40G of data.

What is the technical principle? Will UFS have a life risk?

Not at all, everyone can use it with confidence, believe in the professionalism of Xiaomi and chip manufacturers, and don’t be rhythmic.

Simple science about bad block replacement management, because memory devices can only be replaced with reserved space units after bad blocks are found, once there is not enough reserved space, the memory chip will be completely unusable. We not only reserve enough space according to users’ habits, but also optimize the management of Cache to reduce the occurrence of erasure and bad blocks. At the same time, we support cloud control to adjust the reserved area of bad blocks according to users’ conditions after long-term use to ensure the stability of the system. According to the current model of heavy users, under the condition of writing 40GB of data every day, the expansion chip of 256GB can still be guaranteed for more than 10 years, and the expansion chip of 512GB can be guaranteed for more than 20 years. Please rest assured.

In order to ensure the best storage experience, it is necessary to realize the deep collaboration between the host file system and UFS, which has been reflected in the FBO’s refreshing storage function before. With the same concept, Xiaomi also deeply intervened in the resource management of UFS on the host side based on file management, realizing "data unnecessary non-writing (UFS)" through software, and "writing data unnecessary non-migrating" through software+firmware, reducing the amount of writing and achieving better wear-leveling.

Can the old model be upgraded and supported?

Need mobile phone manufacturers, supply chain manufacturers to match, and to do calibration when mobile phone production, so the old model does not support.

Why don’t some versions support the same Xiaomi 14?

For the sake of supply chain security, we purchased a number of memory chips. Although Xiaomi share all the technologies from the supplier, some manufacturers haven’t had time to adapt. In fact, there were objections a few days before the listing. Finally, General Manager Lei made a decision: Don’t waste good technology, just make it clear to everyone. If it is more than 8G/16G, it is normal to enjoy the technology. I hope everyone will understand.

Driven by Xiaomi, mainstream memory chip manufacturers at home and abroad will adapt one after another.

Can other manufacturers use this technology?

Xiaomi has contributed the standard to the UFS Association. In order to respect originality, we ask chip manufacturers to do a little time protection. In the near future, major mobile phone manufacturers should adapt to this function. Since its establishment, Xiaomi has always hoped to promote the progress of the industry with all manufacturers. This needs no explanation. It should be obvious to all.

According to Lei Jun’s previous introduction, the actual real space of a nominal 256GB mobile phone storage actually exceeds 275GB. Among them, 93.1% of the space is really available to users, and the remaining 6.9% is called Over Provision, or OP for short, which is the space occupied by internal management of the memory. This part of the space cannot be used during the use of the mobile phone.

Xiaomi has worked closely with memory manufacturers. . This process requires a deep understanding of the working principle of the memory to ensure that the OP area space is compressed without affecting the performance and life of the memory. After many tests and optimizations, Xiaomi found an ideal balance point.

. In this process, Xiaomi needs to deeply customize the file system to ensure that it can manage this new space correctly and efficiently. Xiaomi’s engineers have finally achieved this goal after countless experiments and optimizations.

Scan the code with your mobile phone and enter with the green code. Nowadays, scanning the health code has become the habit of most Chinese people when they go in and out of communities, companies, shopping malls, or take transportation or even go to the vegetable market to buy food.

The small "health code", like a necessary "life pass", has played a great role in preventing and controlling the COVID-19 epidemic and promoting the resumption of work, production and business. The "health code" rooted in mobile internet technology is replacing the traditional proof method to help people flow safely and orderly during epidemic prevention. According to incomplete statistics, since the outbreak, 31 provinces across the country have achieved full coverage of health codes.

How did the health code appear? How does it achieve "one yard goes to the world"? What role does it play in the construction of smart cities and social public governance?

It is very convenient to pass on the code.

Take out your mobile phone, enter a social platform, click on the "Guizhou Health Code" applet, and register my information by scanning the code-61-year-old Wang Yinghua, a citizen of Guiyang City, Guizhou Province, knows this "program" by heart. Whether going for a walk in the park or going to the vegetable market to buy food, he will first take out his mobile phone and do it again.

"With the health code, you can see the health status at a glance, so you don’t have to be so troublesome as before." Wang Yinghua said that before there is a health code, for the sake of epidemic prevention and control, it is necessary to register personal name, address, mobile phone number, ID number and other information when entering and leaving communities, hospitals and parks. "It is too inconvenient and there is no other way." When the epidemic was serious, he once took his grandson to a community hospital and waited in line for half an hour before entering the door.

Nowadays, health code has become an important tool for people to seek medical treatment, work, shop and travel. This kind of "code" traffic makes people travel more conveniently and quickly, and also makes the epidemic prevention and control more efficient and the city operation more scientific and orderly under the background of normalization.

"I feel particularly at ease when I see the health code, especially when I see the residents scanning the green code." Yan Yan, deputy director of Jingshan Street Community Construction Office in Dongcheng District, Beijing, has been on duty at the community prevention and control bayonet since the Spring Festival this year, and was removed a few days ago. Like many colleagues, she was deeply impressed by the changes brought by scanning code.

Yan Yan introduced that since the outbreak, there have been more than 400 workers in Jingshan Street who are responsible for returning to Beijing and returning personnel, and sinking cadres and volunteers on duty in the community. In the past, their main energy was spent on manual investigation and manual registration of residents’ information through "knocking on the door" and telephone calls.

At the beginning of March this year, health codes began to be used in Beijing. This not only lightens the workload of Yan Yan and his colleagues, but also greatly improves the work efficiency. For example, she said that relying on the cooperation of health code and residents’ travel code, staff can quickly understand the authenticity and accuracy of epidemiological investigation information of relevant personnel, the situation of floating personnel and residents’ statements, so as to make epidemic prevention and control more accurate.

Statistics show that the whole country has basically achieved full coverage of health codes except Hong Kong, Macao and Taiwan. The people’s think tank recently conducted a questionnaire survey on 5,928 respondents through the Internet and WeChat public platform. The results show that over 90% of the respondents have applied for health codes, and the public feels better about the use of health codes as a whole, and has a high recognition of its role in epidemic prevention and control.

"From a macro perspective, the health code has solved the problem of people’s safe and orderly flow across regions in the context of local epidemics and promoting the resumption of work and production, and has further improved the grid service system while helping the prevention and control of community epidemics." Wang Hong, a researcher at the People’s Think Tank, said.

Safe, accurate and not disturbing.

At the beginning of February this year, many residents in Shenzhen were surprised to find that they don’t need to fill in information or apply for a temporary pass at the gate to enter and leave the community. They just need to log in to the platform such as "Shen I You" at home to enter health information, get the exclusive health code, and light the "code" when entering and leaving the community. With the launch of health codes, Shenzhen has become the first city in China to realize "traveling by codes".

Can you make a "code" that can replace the paper pass, so as to reduce the direct contact between people and the repeated filling of information? This is the original intention of Tencent Cloud government team to develop Shenzhen Health Code.

"From paper proof to digital code, it seems simple, but actually it takes a lot of hurdles." Li Xiaohui, technical director of Tencent Cloud’s government affairs industry, said that from the process point of view, it is necessary to assist the local government to quickly define and establish data collection standards, and design a set of technical architecture that can support tens of millions of users online and ensure its availability. From the goal, health code should realize the function of quickly transmitting relevant data from the front line to government decision-making institutions, and timely transmitting government decision-making and service information to residents and enterprises; At the same time, enterprises only build channels and platforms, and do not keep relevant data to ensure the data security of public information.

Despite the difficulties, the first version of Shenzhen Health Code took only seven days to go online, and the version was constantly updated according to local needs. Behind the innovative speed is the full commitment of Li Xiaohui and his colleagues. "Almost all our departments are involved, and other product teams and security teams of the company guarantee the whole process. It can be said that the company is supporting it."

Today, Internet companies such as Tencent and Ali are providing technical support for health codes in more and more cities.

Generally speaking, the health code systems in different places have many common characteristics. First, they are convenient and fast, and they fully consider the age and education level of residents. For example, Hangzhou Health Code launched the agency application, and the health code was displayed by swiping the citizen card, which solved the problem of using the health code for people without smart phones. The second is safety. For example, the Beijing Municipal Government stipulates that all data of "Health Treasure" shall be kept in the municipal government and used only for epidemic prevention work; And every time the day expires, all relevant data will be invalid, so as to achieve automation of information protection and standardization of data storage. The third is accuracy. Through the verification and comparison with the national databases such as confirmed and suspected case database, close contact database and inter-provincial health code database, and the data of health care, public security, railway, civil aviation and other departments, authoritative and reliable results are generated.

"In the prevention and control of the epidemic, the health code only helps and does not add chaos." Pan Helin, executive director of the Digital Economy Research Institute of Zhongnan University of Economics and Law, said that the health code only obtains basic information and health information of residents; In the use process, mainly through color recognition, and only part of personal information is displayed, which greatly reduces the risk of personal privacy exposure.

Let social governance have more temperature.

With the normalization of national epidemic prevention and control, how to unify local health code standards and truly realize "one code goes to the world"?

At the end of April this year, a series of national standards of Personal Health Information Code were released, which means that the personal health information code will realize the unification of coding system, display mode and data content. Experts said that to fully realize the mutual recognition of health codes in different places, it is necessary for all places to further improve the prevention and control system and mechanism, recognize the health codes produced by outsiders, and upgrade the local health code system according to the new national standard.

Li Xiaohui suggested that relying on the existing national integrated government service platform as the central hub, the local health code systems should be opened, so that each province’s health code connected to the central hub can realize "one access and all mutual recognition". "Use the central hub position of the national platform to connect and manage the distributed health code services in various places."

Regarding the future trend of health code, the survey results of People’s Think Tank show that over 90% of the respondents hope that health code will play a more important role in the post-epidemic era, especially in the fields of health, urban governance, transportation and entertainment.

Li Xiaohui said that Health Code is a product that serves the people’s livelihood, and many new ideas have been hatched in the research and development process. For example, in the future urban governance and urban service scenarios, digital map code is a good channel to connect residents, governments, legal persons and social organizations, and more services can be provided through technological upgrading in the future.

Only by improving the relevant institutional mechanisms can health codes play a greater role. Dong Yizhi, a lawyer of Shanghai Zhengce Law Firm, suggested that laws and regulations should be improved as soon as possible, and the authority of government departments to capture and use data and information related to the epidemic, as well as the supervision mechanism and legal responsibility should be clarified. In the future, the government can purchase services to ensure the public welfare of projects and effectively supervise R&D enterprises.

"Health code brings a lot of inspiration to social governance innovation and smart city construction." Pan Helin said that the rapid establishment of a cross-provincial mutual recognition mechanism for health code information has accumulated experience for the national unification of other types of government information in the future; This health code comprehensively applies artificial intelligence, big data, mobile communication, cloud computing, blockchain and other technologies for actual combat training, providing a new means of refined, accurate and rapid management for social governance.

"When everyone can submit their personal needs to the public platform conveniently and quickly, it means that urban governance will pay more attention to humanistic care in the future, and social governance will be more temperature-sensitive." Pan and Lin said.

Hangzhou put a health code on the road.

The municipal road health monitoring system "Smart Road Chief", an important module of the third phase of the "Cloud City Management" launched in Xiacheng District of Hangzhou, Zhejiang Province, has recently been launched. The system divides the pavement in the downtown area into millions of square meters, and each square meter corresponds to a red, yellow and green "health code". Red means "unhealthy", yellow means "sub-health" and green means "healthy". The system puts corresponding positioning and information labels on millions of points, and feeds back 16 diseases such as potholes, subsidence, cracks and defective manhole covers on the points to the cloud in real time through the "intelligent sensing equipment" that moves 24 hours, so as to achieve real-time monitoring, classification and identification, intelligent push and continuous follow-up. "We use health codes to manage roads, inspired by epidemic prevention and control." Zhang Yiheng, director of the Xiacheng Urban Management Bureau Office, said.

The core of "Smart Road Length" is the calculation and transmission of big data. How to make data more secure and reliable and realize sharing? The system uses blockchain technology. The data analyzed and output by the system is authorized by the blockchain encryption algorithm and certificate permission, and the function of "road information storage and certificate sharing" is implanted in the "road intelligent system", which not only can effectively ensure that the road maintenance index is safer, more authentic and more convenient, but also can share the generated data with traffic police, transportation, municipal administration and other departments. After ordinary citizens install mobile phone sensors to upload data, they can also be converted into incentive values to get rewards, thus truly realizing "road surface can be read and managed with temperature".

At present, Xiacheng District has achieved information coverage for nearly 200 roads and millions of points in the area. The average time for finding pavement problems has been shortened from 5-7 days to 1-2 days.

According to reports, the "Smart Road Length" system will be upgraded in the next step, and problems such as road surface water and road garbage will be included in the monitoring scope.
