Traffic law enforcement was once unable to effectively target

Cheng Xinghuan, a reporter from Jinyang. com, reported: On the Guangdong Minsheng Hotline today (28th), Wang Fumin, deputy director of Guangdong Province, revealed that at present, more than 20 online car rental platforms have obtained business licenses in Guangdong Province, and 52,260 online taxi driver’s licenses and 50,138 online taxi transportation licenses have been issued, accounting for 17.7% and 30% of the national total respectively, ranking first in the country. However, in the management of online car, Didi Chuxing, a monopoly, has refused to accept data access for supervision, both in Guangdong and in the whole country.

However, for the rapid development of network cars, the supervision of the industry has lagged behind, especially in Yueqing, Wenzhou. On the evening of 26th, Guangdong Provincial Communications Department, Guangzhou Municipal Communications Commission, Shenzhen Municipal Communications Commission and Dongguan Transportation Bureau talked about Didi respectively. In Shenzhen, according to the network car data transmitted by Didi Platform to the government supervision platform (the ride data has not been transmitted), there are still nearly 5,000 drivers and nearly 2,000 vehicles in the platform that have not obtained the operating documents. In Dongguan, there are 19,492 drivers (including 15,584 drivers who obtained the taxi qualification certificate before November 2016), and only 5,204 vehicles have obtained the network car transportation certificate. However, Didi Platform has more than 30,000 drivers and more than 20,000 vehicles providing online car service in Dongguan.

However, even if the government departments intervened early, Didi still "went its own way". In the notification of the interview in Dongguan, the rectification measures promised by Didi Company have not been effectively implemented. For example, it promised not to distribute orders to non-Dongguan license plate vehicles from June, but some citizens still reported that non-Dongguan license plate vehicles would take orders at night. In this year, Dongguan investigated and dealt with 292 cases of illegal network car service, including 61 cases of illegal network car service provided by Didi Company. This number is not worth mentioning compared with the operation of nearly 10,000 driving without a license and 15,000 unlicensed vehicles.

As to why government departments can’t supervise these "black cars", Wang Fumin said that Didi refused to access data to government departments for supervision not only in Guangdong, but also in the whole country, and refused to provide detailed data on drivers and operating vehicles, so it was impossible to carry out targeted law enforcement and could only rely on the original containment. After the rectification of Didi at the end of September, all management departments will obtain the complete data uploaded by Didi, and then effectively retreat, which is expected to be completed before the end of the year.

In addition, after the Wenzhou Yueqing hitchhiking case, Wang Fumin predicted that the next step would be to introduce a policy to put aside the customer service and directly connect with the public security organs.

It is always difficult for people to remember the second and third, but they can always remember the first clearly.

You may forget what it feels like to hug the opposite sex for the second time, but you must remember the throbbing of the first hug. Just like you may not remember the second car you took and drove, but you are impressed with the first car.

So, do you remember what was the first car you sat in and drove? I believe most people’s answer is only three words:.

People who came from the era of "owning Santana and traveling all over the world are not afraid" always have a memory in their minds, that is, the square front, the VW logo carved on the plastic grille and the classic "Shanghai Volkswagen" tail logo …

When the time train galloped past forty platforms, the meaning of "SAIC Volkswagen" was very different for China automobile industry and even everyone. During these forty years, SAIC-Volkswagen witnessed the rise of China’s automobile industry and the great achievements of reform and opening up. At the same time, it also gained its own prosperity as the first joint venture automobile company in China.

Yesterday, SAIC Volkswagen opened a neon for the China auto market.

Let’s temporarily adjust the time back to the time node that crossed in the 1970s and 1980s.

At that time, there were not many small cars running in China, except for Beijing 212 and Shanghai brand cars. Old friends who came from that era probably have the impression that there are always several dark green 212 cars and several white or blue-green Shanghai cars parked in the tree-lined government compound.

In that era when the global automobile industry entered prosperity, China automobile industry can still be described as "barren".

After the tide of reform and opening up came, the state decided to vigorously develop the automobile industry. So in 1978, China made initial contact with German audi ag. After many arguments, in 1984, Shanghai Car Factory and German Volkswagen formally signed the joint venture and cooperation regulations, and the two sides jointly established Shanghai Volkswagen Co., Ltd.

The first car introduced into China market by Shanghai Volkswagen Joint Venture Company is the "Santana" which will be popular all over the country in the next 30 years. However, as the first joint venture car in China, Santana’s landing road is also quite tortuous.

China in the 1980s did not have a modern automobile industry base. Therefore, the first batch of Santana cars launched by Shanghai Volkswagen for the China market can only be produced by CKD parts imported and assembled. On the assembly line, the workers of Shanghai Volkswagen can only assemble the whole vehicle by hand.

In fact, while bringing Santana, Shanghai Volkswagen also shoulders an important mission, which is to bring advanced production technology and manufacturing technology of western automobile industry to China after the establishment of the factory. In other words, Shanghai Volkswagen shoulders the responsibility of "starter" of China Hyundai Motor Industry.

After a period of "extensive production", Shanghai Volkswagen invited experts from German Volkswagen to Shanghai for guidance in order to improve production capacity and efficiency, and introduced international manufacturing standards and production equipment. Through the intensive production line upgrade, Shanghai Volkswagen has increased the annual production scale of Santana to more than 50,000 vehicles in just six years. However, at this time, Shanghai Volkswagen still lags behind the development goal of "within 7 years, the localization rate of Santana will exceed 80%".

Then, after establishing the modern production process and manufacturing technology, the next plan of Shanghai Volkswagen is to establish a complete automobile supporting supply chain industry in China based on Santana.

In the TV series Blossoms Shanghai, No.120 Jinxian Road left an impression on the audience.

In reality, No.120 Jinxian Road is the original site of Shanghai Piston Factory. When Shanghai Volkswagen was determined to establish a modern automobile supply chain system, Shanghai Piston Factory signed a technology license transfer contract with German Kolbenschmidt Co., Ltd. to introduce piston manufacturing technology to purchase key manufacturing planes and test equipment.

Starting from the piston factory, Shanghai Volkswagen has also established a large number of spare parts suppliers since the 1990s, and established quality standards in China that meet German Volkswagen and international standards. At this point, China automobile supply chain industry has also entered a stage of prosperity and development.

It can be said that Shanghai Volkswagen, which started in the 1980s, not only brought brand-new Santana cars to the China market, but also brought a brand-new beginning to the automobile industry in this ancient land.

This joint venture car company is the first to introduce foreign capital, global standards and advanced manufacturing systems into China’s automobile industry. To some extent, the development history of Shanghai Volkswagen is the development history of China automobile industry marketization. As a pioneer of the whole industry, Shanghai Volkswagen is worthy of the title of "industry beacon".

Today, SAIC Volkswagen sets an industry benchmark with tens of millions of trust.

Today, the production and sales scale of SAIC Volkswagen has already exceeded 10 million, and it has become the first passenger car enterprise in China with a cumulative output exceeding 28 million. 40 years, 28 million, these data reflect the stable and prosperous development of SAIC Volkswagen.

Today, SAIC Volkswagen has three brands, Volkswagen, Audi and Skoda, and continues to play a leading role as a joint venture car company with an annual sales of one million. Of course, the achievements made by SAIC-Volkswagen in the past 40 years are not only remarkable achievements in the market.

More importantly, SAIC Volkswagen has always created a new situation in the automobile industry.

If we say that during the period from the 1980s to the 1990s, SAIC-Volkswagen was introducing advanced technologies from the western automobile industry to help China’s modern automobile industry grow sturdily; Then, during the period from 2000 to 2000, SAIC Volkswagen made more wonderful contributions to the automobile industry with its own progress.

Since the Santana 2000 project at the beginning of the new century, SAIC-Volkswagen has started the road of independent research based on the global technical and design advantages of Volkswagen and the actual demand of China local market. As the first joint venture car company in China, SAIC Volkswagen has also become the first joint venture car company in China to independently develop new models.

When SAIC Volkswagen has the tradition of independent research, it has brought many refreshing products.

Volkswagen, through its insight into the needs of domestic household consumers, has created a large-space body and brought a quality experience to a total of 5 million home users; Volkswagen, on the other hand, deeply observes the young user groups and has become a travel partner of more and more young people with high value built by face value and performance; Volkswagen, as a large-size SUV with superior volume, is deeply favored by domestic middle and high-end users, and has gone abroad to dominate the North American market under the name of Atlas.

In fact, SAIC Volkswagen has many self-developed models, such as today’s L Pro, which not only brings a new experience to domestic consumers. More importantly, this new car pioneered the in-depth cooperation between SAIC Volkswagen and DJI, a China science and technology enterprise, and helped SAIC Volkswagen, which has a history of 40 years, formally enter the intelligent era with its intelligent performance comparable to that of new forces.

"Innovation" is the best summary of SAIC Volkswagen today.

From self-developed models to the development of advanced intelligent technology, SAIC Volkswagen has been at the forefront of the times every time. Undoubtedly, with the spirit of innovation as the basis of enterprise development, SAIC Volkswagen will definitely open up a new situation in the future.

What will the future of SAIC Volkswagen look like in 2040?

On the 40th anniversary of the establishment of SAIC Volkswagen, SAIC Motor Group, which came from Shanghai Car Factory step by step, signed an extended joint venture agreement with audi ag. According to the agreement, the joint venture period of SAIC Volkswagen will be extended for another 15 years to 2040.

The decision of the two parties to the joint venture also directly opened the door to the future for SAIC Volkswagen. We can’t help wondering what kind of situation SAIC Volkswagen will create when the era of intelligence and electrification comes.

The pulse of the times is constantly beating, and SAIC Volkswagen is always moving forward. As early as 2021, when, and ID.3 slowly drove off the production line of Anting MEB factory, SAIC Volkswagen opened the prelude to the future.

It can be seen that in the face of the surging intelligent electric era, SAIC Volkswagen has actively planned the enterprise transformation layout. At the same time, the three major ID. series models built on MEB platform have stood firm in the joint venture camp. In November, SAIC Volkswagen ID.3 delivered more than 14,000 new cars and became the king of pure electricity sales among joint venture brands.

When SAIC Volkswagen’s new energy pace is getting faster and faster, this joint venture car company has also begun to think about a "philosophical question" that all traditional car companies must consider-facing the future, should we take the new energy route or keep the fuel route?

SAIC Volkswagen, which has developed for 40 years, has already accumulated a strong system strength, and the answer it brings is "all want". In the field of fuel vehicles, SAIC Volkswagen is committed to promoting environmental protection, high efficiency and intelligence of fuel vehicles. After popularizing more efficient 300TSI power, SAIC-Volkswagen also launched the strategy of combining oil with electricity. The Volkswagen Tiguan L Pro, which has the same intelligent performance as the smart electric model, has also become a popular model at present.

Based on the sales support of fuel vehicles, SAIC Volkswagen can also explore the new energy field more quickly. In November 2024, SAIC Volkswagen launched a brand-new luxury brand AUDI on the basis of Audi, and made its debut in the first concept car. After starting the alphabet, SAIC Volkswagen will further promote the transformation of high-end new energy.

It is reported that AUDI’s first new car, AUDI E, was designed by Audi’s German team. At the same time, the core three electrical components and intelligent system of this car came from SAIC Volkswagen’s supply chain system. In the close cooperation between SAIC and Volkswagen, we believe that the brand-new AUDI brand can create intelligent electrification products with strong strength for China users.

Of course, SAIC Volkswagen also showed a faster speed.

In 2025, AUDI E, the first model of the new brand, will be delivered in mass production. At the same time, within three years, the AUDI brand under SAIC Volkswagen also plans to launch three electric vehicles, covering the B-class market and the C-class market, and quickly seize the high-end smart power camp highland.

Conclusion:

?

From the time when the first Santana was produced by knocking, to the time when Pro/ Tiguan L Pro and other models were rolled off the assembly line from a clean and tidy smart factory, SAIC Volkswagen took 40 years to set countless firsts in the history of China automobile industry.

I believe that many friends’ love for SAIC Volkswagen comes from their feelings. But what the author wants to say is that when we get out of the feelings of the years and the memories of the past, SAIC Volkswagen has always been a trendsetter standing on the top of the wave.

Nowadays, what SAIC Volkswagen is facing is not only the glory of the past forty years, but also the opportunity of the next fifteen years and the next fifty years. We are also willing to believe that in the next era, SAIC Volkswagen will bring us more touches and more surprises.

Xinhua News Agency, Beijing, November 15th Topic: Face-to-face hot spots: Focus response of COVID-19 vaccine immunization.

Xinhua News Agency reporter Peng Yunjia, Mu Tiecheng

Why do you need a booster shot? Who needs to fight? When will you call? What kind of booster is inoculated? The National Health and Health Commission responded to the hot issue of vaccination with booster shots in COVID-19 on the 15th.

Focus 1: Why do you need a booster shot?

From the research results at home and abroad, the complete vaccination of COVID-19 vaccine has a remarkable effect in preventing severe illness and reducing mortality. However, after vaccination for a period of time, the protective effect of the vaccine on some people may be weakened. Strengthening immunization at the right time can make the neutralizing antibodies that have been gradually reduced grow or rebound rapidly, thus producing better protective effect.

Focus 2: What is the age range of people who can get booster shots at present? Who are the target groups?

According to the needs of epidemic prevention and control, strengthen immunization among people aged 18 and above who have been vaccinated with the above vaccine for 6 months.

At present, priority is given to strengthening immunization among people at high risk of infection, key personnel and elderly people who guarantee the basic operation of society in Covid-19. For other people who meet the requirements and need vaccination, they can also be vaccinated according to their needs.

Focus 3: How long is the interval between vaccination booster and whole immunization?

At this stage, intensive immunization will be implemented after 6 months of vaccination. That is, after the second dose of inactivated vaccine is inoculated in Covid-19, it is generally required to have an interval of 6 months before the booster dose can be inoculated again. Six months after inoculation of adenovirus vector vaccine, booster immunization was carried out.

Focus 4: At this stage, what vaccines can be used for booster shots?

According to the progress of vaccine research and development in Covid-19 and the research and demonstration of relevant departments, there are inactivated vaccines from Sinopharm Zhongsheng Beijing Company, Beijing Kexing Company, Sinopharm Zhongsheng Wuhan Company and adenovirus vector vaccine from Tianjin Kangxinuo Company.

Focus 5: What kind of booster shots should individuals get?

At this stage, the original vaccine has been used to strengthen immunization.

Among them, people who used the same inactivated Covid-19 vaccine to complete two doses of vaccination should, in principle, use the original inactivated vaccine for one dose of booster immunization; People who use different inactivated vaccines to complete two doses of vaccination should, in principle, give priority to one dose of booster immunization with the same vaccine as the second dose of inactivated vaccine. In case that the second dose of the same vaccine cannot be supplied any more, they can use the same vaccine as the first dose of inactivated vaccine for one dose of booster immunization. People vaccinated with adenovirus vector vaccine should use the original vaccine to strengthen immunization.

Focus 6: Where to strengthen the needle? What are the precautions?

In principle, the relevant units shall organize and implement the immunization of people infected with high-risk groups and key positions to ensure the basic operation of society; Other people can make an appointment for vaccination at the designated vaccination unit in the jurisdiction. See the official information released by the local health department or CDC for specific vaccination information.

Before vaccination, according to the previous vaccination certificate, confirm whether you have been vaccinated all the time and have completed the whole vaccination for more than 6 months. You need to carry your ID card, vaccination certificate, etc. during vaccination, and do personal protection according to local prevention and control requirements, and cooperate with the on-site vaccination staff to ask; Doctors should be informed of their past diseases and whether they have used drugs recently.

After inoculation, observe for 30 minutes according to regulations; Keep the skin of the inoculated area clean and avoid scratching the inoculated area with your hands.

　　"The increasing blockade and sanctions imposed by the United States have caused Cuba’s current economic difficulties. But Cuba will not wait for the enemy to correct its criminal policy. Cuba must persist in its efforts and seek ways to overcome US sanctions and blockades with wisdom, dedication and creativity. "

　　On July 26th, local time, Cuban Vice President Valdez made the above statement at the commemoration of July 26th National Uprising Day in the country.

　　More than 60 years ago, the United States broke off diplomatic relations with Cuba after the revolution, and then began a long blockade of this socialist country. In the American think tank — — According to the Center for Economic Policy Research, the US sanctions against Cuba are the "oldest and most restrictive" of all existing economic pressure mechanisms.

　　In a recent report, the think tank pointed out that although the government has made some progress in restoring diplomatic relations with Cuba and relaxing certain trade restrictions, these measures have basically been completely reversed during the government’s term of office. After the Biden administration came to power, it still maintained most of the policies toward Cuba during the Trump era.

　　Decades of harsh blockade have seriously affected Cuba’s economic development and people’s lives. For nearly 30 years, the United Nations General Assembly has passed a resolution every year demanding that the United States end its blockade of Cuba. However, in the face of the world’s just voice, the United States still goes its own way.

　　Even many American politicians are increasingly worried that the "sanctions superpower" of the United States will eventually push itself into a desperate situation.

　　Sanctions target: more than the world60%Low-income countries and regions

　　Washington post recently published a long investigative report, pointing out that sanctions have become a key tool of American foreign policy.

　　Up to now, the United States has imposed unilateral sanctions on one third of the countries in the world, with more than 15,000 effective sanctions, ranking first in the world, and far ahead of other countries and organizations.

Washington post chart

　　The survey found that the number of targets sanctioned by the United States has increased dramatically in recent presidents, especially Trump and Biden.

　　Since the beginning of this year, the US government has continued to introduce sanctions at a record speed. Washington post’s analysis based on the income data summarized by the World Bank shows that more than 60% of low-income countries and regions in the world are suffering from some kind of sanctions imposed by the US government.

Washington post chart

　　According to the report of the Center for Economic Policy Research in the United States, the evidence that unilateral economic sanctions have caused serious harm to civilians around the world is "overwhelming".

　　As we all know, extensive sanctions will hinder the overall economic growth of a country, and sometimes lead to or prolong the economic recession or even depression of the target country. Sanctions also hinder the target countries from obtaining necessities such as food, energy and medicine, hinder humanitarian assistance, and thus create more poverty, hunger, disease and a large number of avoidable deaths.

Screenshot of official website, Center for Economic Policy Research in the United States

　　This report specifically mentions that the legitimacy of American unilateral sanctions has been widely questioned by the international community.

　　Some people think that only the UN Security Council has the right to legally impose sanctions. On the contrary, any unilateral sanctions or multilateral sanctions without the approval of the Security Council violate the principle of national sovereignty and undermine the international rule of law.

　　At the same time, the unilateral economic sanctions imposed by the United States also violate the spirit of multilateral documents such as the Charter of the Organization of American States, which the United States itself participated in.

　　In addition, many economic sanctions imposed by the United States also violate international human rights law and a series of treaty obligations, including the Vienna Declaration and Programme of Action and several resolutions of the United Nations Human Rights Council.

　　More importantly, many US sanctions are based on unreliable domestic laws. Most of them are implemented according to the International Emergency Economic Powers Act of 1977, which gives the U.S. government the power to determine that a specific country "poses a special threat to U.S. national security, foreign policy or economy."

　　However, the above report pointed out that in many cases, such statements — — For example, the political situation in Venezuela or Zimbabwe poses an "extraordinary threat" to American national security to some extent — — There is almost no basis.

Screenshot of official website, Center for Economic Policy Research in the United States

　　Must we choose it between diplomacy and war?

　　More and more illegal unilateral sanctions are not only being scolded constantly, but also their actual effects are seriously in doubt.

　　American sanctions against Cuba, Iran and North Korea have been going on for decades, but it has been proved that these countries have never given in, although they have been greatly hurt by sanctions.

　　The latest example is Russia.

　　After the outbreak of the conflict between Russia and Ukraine, the United States led western allies to impose more than 16,000 sanctions on Russia in order to effectively reduce Russia’s "war resources". But more than two years later, both on the battlefield and economically, the western abacus of "making Russia" has almost disappeared.

　　To the west’s surprise, Russia’s economy not only grew significantly by 3.6% last year, but also seems to continue to maintain a strong growth momentum.

　　The latest World Economic Outlook report released by the International Monetary Fund (IMF) predicts that Russia’s economic growth rate will exceed that of all developed economies including the United States this year. It is estimated that Russia’s gross domestic product (GDP) will increase by 3.2% and 1.8% respectively this year and next, both higher than previously expected.

　　Former official of the US Department of Commerce, currently working for a Washington think tank — — Bill Reinsch, an international business expert at the Center for Strategic and International Studies, said that sanctions "as the only thing between diplomacy and war" have become the most important foreign policy tool of the United States. "However, no one in the (American) government can be sure whether the whole sanctions strategy will work."

　　What is more terrible than this embarrassment is the anti-bite effect of American unilateral sanctions.

　　Washington post reported that since financial sanctions became a new tool of American unilateral sanctions with the help of dollar hegemony, American policy makers began to use this power more and more frequently.

　　However, with the increasing sanctions, challenges have emerged. Not only Wall Street and America’s European allies may be hurt by secondary sanctions, but also more countries are looking for ways to get rid of dollar dependence in order to avoid sanctions, which leads to the gradual erosion of dollar hegemony.

　　A poll earlier this year found that most Americans believe that if American sanctions violate international law, interfere with humanitarian assistance, damage the livelihood of ordinary people, or hinder climate change cooperation between countries, the United States should cancel these unilateral coercive measures.

　　Even some people at the top of the US government have realized the risk of abusing unilateral sanctions.

　　Jacob Lew, the US Treasury Secretary during the Obama administration, publicly warned that the excessive use of unilateral sanctions must be curbed, because it "may eventually weaken our ability to implement effective sanctions".

Diversified business is hard to say success, and channel reform still needs to be promoted.

Author Wang Yuanlei

Dong Mingzhu is never short of topics.

On December 13th, a video of Dong Mingzhu’s speech at the induction ceremony of Gree’s 2023 college students was circulated on the Internet. In his speech, Dong Mingzhu criticized Meng Yutong again, which attracted a lot of attention.

Dong Mingzhu is well versed in marketing.Ten years ago, I gambled with Lei Jun, the founder of Xiaomi, and earned enough traffic for Gree. Two years ago, I made a bold statement to train Meng Yutong, a fresh student, as a successor, and saved hundreds of millions of advertising fees for Gree.

But the problem is that the tougher Dong Mingzhu is, the weaker Gree’s performance is. Although the innovative business has blossomed, Gree is still highly dependent on the air-conditioning business, and its overall revenue and profit are less than expected. Moreover, the channel reform that Dong Mingzhu urgently wants to implement is not ideal.

In early August this year, the 2023 Fortune Global 500 list was released.fail (in) an examination.

When asked "Are you sad?", Dong Mingzhu’s response is still tough: "What’s so sad? It’s not sad at all. It’s better to see the company so healthy and happy than the Fortune 500. What is the significance of the world’s top 500? Just look at the sales revenue. Whether the enterprise is good or not, I know what I know, whether I am sick or not, and I know it. "

Gree’s moat

Gree’s main business is air conditioning, and the difficulties it faces are also mainlyFocus on air conditioning distribution channels.. To understand Gree’s channel dilemma, the story should start from the air-conditioning industry.

The development of air-conditioning industry has a history of one hundred years. From "refrigeration and heating" to "conversion of constant frequency air conditioning" to "intelligent noise reduction and comfortable air supply", air-conditioning technology has been continuously iterated, and the industry has gradually formed giant enterprises such as Gree and Midea, which control most of the market share.

Based on this industry pattern, the competition in the air-conditioning industry is mainly concentrated in three aspects, namelyMarketing, channel and price war. Let’s look at these three points:

In terms of marketing, Dong Mingzhu is recognized as a marketing genius. The "1 billion bet" made Gree earn enough traffic and "cultivated Gree’s successor", and directly promoted his assistant to online celebrity. Dong Mingzhu people were also malicious, and even their own people were embarrassed. They often went to hot search and became Gree’s veritable marketing spokesperson by virtue of people’s appointment.

In terms of price wars, Gree has fought countless price wars in the course of decades of development, from offline store discounts to online live broadcasts, and Gree has repeatedly participated in industry price wars.

In addition to marketing and price factors, looking at the development process of air-conditioning industry, the iterative speed of air-conditioning technology update is slow, and it is basically difficult to open the gap.The real gap lies in the channel..

Any leading enterprise has a strong moat. The channel is the moat of Gree. In the development of more than 30 years, Gree has formed a solid sales channel system-Provincial regional sales companies, county levelAgent, terminal sales outlets.

Among them, Gree holds shares in provincial regional sales companies, and the provincial sales companies directly control county-level agents, and Gree and county-level agents do not settle accounts.

In addition, during the seasonal change in Xia Dong, Gree responded to fluctuations in production byProvide discounts for dealers and return funds for goods.In turn, it is deeply bound with dealers.

Under this channel model, Gree has formed a solid sales channel system in the whole country, which has become the main factor for Gree to sit firmly on the throne of air conditioning overlord for a long time.

02

Fist products are not hard.

However, judging from the development in recent years, Gree’s leading position is being shaken, and one of the main manifestations-fist products are not hard.

As a leader in China’s home appliance industry, Gree’s performance in the secondary market is remarkable. When the stock price is the highest, it is about 62 yuan per share.distribute bonusIn fact, it is a proper "cash cow", so that Dong Mingzhu once said to the outside world, "We have paid more than 100 billion dividends to the stock market, and paying dividends to shareholders every year is the most balanced return on investment."

Behind this is the performance support of fluctuating growth. In July 2019, Gree was selected into the Fortune Global 500 for the first time with a revenue of 198.153 billion yuan, ranking 414th, and its revenue increased by 0.02% year-on-year.net profitIt reached 24.697 billion yuan. Since then, GreecontinuouslyList the top 500 in the world, ranking 436th, 488th and 487th respectively.

In 2022, Gree’s revenue was 189 billion yuan, a year-on-year increase of 0.6%. "When the moon is full, it will lose money, and when the water is full, it will overflow." Gree’s development track seems to confirm this truth. In this year’s list of the world’s top 500 companies, Gree and the top 500 companies have a revenue difference of 35 billion yuan, which is a pity.

This is not without warning. Since December 2020, Gree’s share price has continued to fall, and it is currently about 33.14 yuan per share.The higher point has dropped by about 45%.The market value evaporated by nearly 200 billion yuan.

On the other hand, its performance is hardly satisfactory. Even in the past three years, Gree’s revenue has not increased significantly. (see the picture below)

Air conditioning is the lifeblood of Gree, accounting for 71.36% of its revenue in 2022. However, in terms of air conditioning, the most competitive product, Gree’s air conditioning revenue has not increased significantly in the past three years (see the figure below). as soon asmarket shareLook, in 2022, Gree’s home air conditionerThe market share has lost the first place in the market.The throne of.

These two years have followedCooling of air conditioning marketThe continuous negative growth of domestic air-conditioning market, coupled with the gradual weakening of air-conditioning season sales by live broadcast, has affected Gree’s overall performance, resulting in unsatisfactory performance.

However, it is worth noting that Midea and Haier continue to grow. As of December 15th, the market value of Midea was 353.5 billion yuan.The market value is 191 billion yuan, and the market value of Gree is over 186.4 billion yuan.Gree is in itAlready at the bottom 2..

Moreover, when Gree fell out of the world’s top 500, Midea and Haier remained among the top 500. Midea has been selected into the Forbes world’s top 500 for eight consecutive years and ranked 278th this year.

Obviously, this can’t be explained by the phrase "poor external environment". In order to promote Gree’s performance growth, Dong Mingzhu has made business adjustments to find a second growth curve.

0three

Gree attacked from all sides.

Knowing and doing are two different things.

Many years ago, Dong Mingzhu has been exploring diversified businesses, but so far, they have all performed poorly. At the two sessions this year, Dong Mingzhu said in the face of media questions, "I think (Gree)Has been transformed successfully, realizing the transformation from a single air conditioner to a full range of household appliances. "

The so-called "all-category household appliances" in Dong Mingzhu include household central air conditioners, household appliances, refrigerators, washing machines, water heaters, water dispensers and various intelligent products, covering all sub-sectors of household appliances.

In addition to the continuous expansion in the field of home appliances, Gree is also involved in many fields such as completely unrelated new energy and intelligent equipment, including cars, energy storage, mobile phones, prefabricated dishes and so on.

The reason why an enterprise is strong is not because of how extensive its products and businesses are, but because it can continuously improve its products and keep innovating. “One meter wide and one hundred meters deep."Is the wisdom of enterprise development.

In the diversified business, one of Gree’s well-known businesses is the acquisition of Yinlong New Energy. In that year, Dong Mingzhu joined Wanda Group in his own name.Five companies, regardless of the opposition, increased their capital by Yinlong New Energy and jointly invested 3 billion yuan.

In 2021, Gree won 47.93% of the voting rights of Yinlong New Energy by participating in the public auction of judicial auction, and Yinlong New Energy became a holding subsidiary of Gree. According to Gree’s 2022 performance report, Yinlong New Energy (now Gree Titanium) has lost more than 1.9 billion yuan and its asset-liability ratio has reached 99%.

In addition to this acquisition, the mobile phone business has also made Dong Mingzhu frequently out of the circle. In 2016, Dong Mingzhu boasted in a speech, "I am proud to say that my mobile phone is the first in the world, not the first in sales. At least I promise consumers that my quality is the first."

But the question is, is the quality of Gree mobile phone really the best in the world? Up to now, Gree mobile phones have launched a total of six models. No matter from which point of view, Gree mobile phones are hardly successful.

These are diversified businesses promoted by Gree. On the whole, Gree’s business is mainly divided into five sections, namelyAir conditioning,life electric、industrial product、intelligent equipmentandGreen energy. In addition, there are some innovative businesses with relatively low revenue, includingMedical health, prepared vegetables, semiconductorsWait.

Judging from the layout timeline, doing what the track fires can, to a certain extent, summarize the diversified business characteristics of Gree, which is doomed to be difficult to achieve success.

In 2020, Dong Mingzhu started live broadcasting with goods in Tik Tok, and over 10 live broadcasts were conducted that year, with a total of nearly 50 billion yuan of goods. With its own efforts, Dong Mingzhu achieved Gree’s sales performance in the last quarter.

This also made Dong Mingzhu see a new direction-live broadcast with goods, so Meng Yutong came to the stage. In September, 2021, Dong Mingzhu recruited Meng Yutong as a secretary, and made a strong platform for Meng Yutong, publicly expressing that he would train Meng Yutong as his successor. During this period, Meng Yutong frequently appeared in online live broadcast rooms.

However, it is worth noting that live delivery has indeed increased the proportion of online sales, but in this way, it has had an impact on Gree’s existing distribution channel system.

0four

Disadvantages of channels

During the "June 18th" promotion in 2020, Dong Mingzhu took the goods off the live broadcast, setting a new record that the single live broadcast sales exceeded 10 billion. Interestingly, however, two days later, Jinghai Internet, a provincial distributor alliance, reduced its holdings of Gree. In July of that year, Jinghai Internet reduced its holdings again.

This is the provincial regional sales company expressing its dissatisfaction with Gree. Dong Mingzhu’s first live broadcast performance was bleak, but in the later live broadcast, the performance was getting better and better, and the reason could not be separated from the help of dealers.

Dong Mingzhu launched offline dealer drainage in the live broadcast. Consumers placed orders through the exclusive QR code shared by dealers, and Gree headquarters directly delivered them, and thenBypass the provincial regional sales companies.. As a result, there was a scene of the counterattack of the provincial marketing department.

In fact, Gree’s sales channels have always had disadvantages. In the course of perennial operation, Gree has formed a community of interests with all links in the channels, but there are obvious problems in this deep binding relationship.

First of all, Gree should be the channel.Leave enough profit margin.Once the profit is reduced, all links in the distribution will lose the motivation to sell goods. Secondly, Gree does not have direct settlement with county-level agents, and there is no direct contact. Gree does not have much right to speak in the intermediate link between provincial sales companies and county-level agents.

In order to develop live broadcast with goods and increase the proportion of online sales in Dong Mingzhu, it is necessary to go beyond the level of provincial sales companies. Moreover, under the background of the great cooling of the air-conditioning market, Gree’s channel system is even more bloated.

There has never been a smooth reform. If Dong Mingzhu wants to move the channel system, it will naturally encounter a lot of resistance. So far, it is still hard to say success. However, the transformation of Gree’s old rival Midea has achieved results.

In 2017, Midea changed its sales company into an operation center. As a result, it changed from earning the difference to earning the service fee, and finally the beauty was formed.twoLevel sales system-factories and distributors.

This change not only reduces the intermediate links, further reduces the cost, but also strengthens the brand’s control over the terminal. Whether it is a price war or a promotion of new products, Midea is more handy.

In 2019,Midea overtook Gree in market share.Since then, the air-conditioning market has been easy to attack and defend, and Gree’s hegemony has changed hands.

according toAccording to the 2022 performance report, according to the data of Aowei Cloud, Midea’s products are online and offline in China in six categories, including household air conditioners, desktop microwave ovens, electric heaters, induction cookers and electric kettles.Market share ranks first in the industry..

Among them, the offline market share of household air conditioners is 33.7%, and the online market share is 33.6%.Ranked first in the industry..

0five

Dong Mingzhu can’t solve this problem.

While reforming the channel system, Gree has been promoting the development of diversified businesses in the past decade, changing the single air-conditioning business structure into an air-conditioning business system driven by multi-core businesses.

However, many business lines that have been tried to develop are average. In 2022, Gree air-conditioning business revenue was 134.859 billion yuan, accounting for 71.36% of the total revenue. Compared with 70.11% in 2021, the proportion of air-conditioning business has not decreased, but has increased by 1.25%.

Looking at the timeline, diversified business attempts, although not ineffective, have indeed declined in the proportion of air-conditioning business, butIt still accounts for more than 70% of total revenue.For a behemoth like Gree, it is hard to say that it is a success. (see the picture below)

At the same time, rivals such as Midea, Haier and Oaks are actively transforming. In addition to the changes in channels, Midea is relatively more successful in business, and has formed a business system focusing on HVAC and consumer appliances, andThere is a small gap between the two businesses in revenue.The overall safety margin is high. (see the picture below)

In 2022, Midea achieved a total revenue of 345.7 billion yuan, a year-on-year increase of 0.68%, which has exceeded Gree by hundreds of billions of yuan.

In 2021, after Meng Yutong joined Gree in a high profile, Dong Mingzhu praised Meng Yutong in the early stage, saying that Meng Yutong "is a person who will not be tempted by external things" and "hopes to spend five years (so that she can) in a very high position", and even went so far as to cultivate a successor.

Now the ending is clear. Meng Yutong left after less than two years in Gree, and managed the "Pearl Feather Boy Selection" (changed to "Gree Pearl Selection")Tik Tok account successfully sucked nearly 3 million powder.. However, it should be noted that live broadcast with goods is difficult to become the fundamental path for Gree to solve problems, and in terms of brands,live-streamingBring goodsIt is also a "double-edged sword".

This year is the first year out of the epidemic. Although the epidemic has ended, the economic development is still under great pressure. The development of domestic investment, consumption and export is less than expected, and the pessimism in the real estate market still exists. Affected by the development of the real estate industry, the air-conditioning industry has also been affected.

At the same time, live e-commerce and interest e-commerce have developed rapidly, the pattern of white electricity market has been rapidly reshaped, and online direct sales have surged. Gree’s distribution system is losing its advantages in the offline era, and it is even more powerless to cope with market changes.

Dong Mingzhu was born in 1954, and now he is 69 years old. Although Dong Mingzhu has repeatedly stressed that "I think my mind is young, like 25 years old", time and tide wait for no man. Facing the ever-changing technological changes, market environment and young consumers’ demands, I’m afraid Dong Mingzhu can’t untie the knot that Gree has unscrewed.

0six

tag

In 2013, on the CCTV stage, faced with the proposal that Lei Jun’s millet turnover could surpass Gree in the next five years, he wanted to bet one yuan. Dong Mingzhu boldly said that he would "bet one billion".

This is a confrontation between the traditional "one brother in manufacturing" and the new economic enterprises. Five years later, standing at the time of 2018, Xiaomi lost Gree. At that time, Gree’s performance was still growing, and Dong Mingzhu also had enough confidence to fight Xiaomi.

However, shortly thereafter, Lei Jun talked about the second gambling contract, while Dong Mingzhu changed his old car-scrapping, symbolically responding "He is willing to renew, of course I can". The reason is self-evident. Dong Mingzhu knows better than the outside world that Gree has reached the top of the mountain on the ramp of air conditioning.

Over the top of the mountain, it is downhill..

After leaving his post, Meng Yutong, the former secretary, talked about topics such as work intensity, working hours and salary on social platforms.

Dong Mingzhu repeatedly responded to Meng Yutong’s departure on different occasions. On November 6, in an interview with Caijing Langyan, he said frankly, "It is impossible to advertise on the platform of Gree and then go outside. This is definitely illegal."

According to the video shared by Tik Tok user "Jeanette Mud Duck", Dong Mingzhu once again mentioned Meng Yutong in his induction speech, saying that he only wanted to use Gree platform as his own online celebrity, which had a bad influence in the company. And said that just thinking about making more money is no different from walking dead.

The grey line of grass snake is a thousand miles long. By comparing Dong Mingzhu’s attitude towards employees and the concept of employing people, it is not difficult to understand Gree’s present situation.

In the face of the accelerated new era of artificial intelligence, the younger generation with more diversified needs, and the changes in online direct sales channels, I am afraid that Gree can win the next battle through the cycle.It will take time to test..

　　[rumor]

　　◎ Our reporter Chen Xi

　　These days, there has been a cold wave weather in China, and the temperature in most areas has plummeted. The cold wave not only affected a wide range, but also was accompanied by rain and snow.

　　Some rumors related to winter have also taken advantage of this cold wave to brush a wave of "existence": "triple" La Nina brings three times the cold, velvet is the warmest clothing material at present, the longer the car is hot in winter, the better, and the frost on persimmon is a preservative … … These rumors mislead the masses and have a negative social impact.

　　Today, the reporter of Science and Technology Daily took stock of the rumors in November one by one and smashed them with the power of science.

　　"Triple" La Nina brings triple cold?

　　Truth: La Nina is just one of the factors that affect winter temperature.

　　According to the latest data released by the World Meteorological Organization, the La Ni? a event that has lasted for a long time (hereinafter referred to as La Ni? a) is likely to continue until the end of this year or longer, which will be the first time in the 21st century that there will be a "triple" La Ni? a, that is, there will be three consecutive La Ni? a winters in the northern hemisphere.

　　As soon as the news came out, it immediately attracted widespread attention, and some netizens gave their own "interpretation": "triple" La Nina will definitely bring three times the cold.

　　In this regard, Zhou Bing, chief expert of climate service of National Climate Center, said that "triple" La Nina is not triple La Nina. "Triple" La Nina means that three consecutive winters from 2020 have been affected by La Nina. The impact is not constantly superimposed year after year, nor does it mean that the climate impact will double year by year.

　　La Nina refers to the phenomenon that the sea surface temperature in the eastern and central equatorial Pacific Ocean continues to be abnormally cold, also known as the anti-El Ni? o phenomenon. When La Nina appears, it is usually accompanied by global climate chaos. At this time, China is prone to cold winter and hot summer, and the number of tropical cyclones landing in China will be more than normal, resulting in the phenomenon of "drought in the south and waterlogging in the north". In Indonesia, eastern Australia, northeastern Brazil and other places, there will be more rainfall; The equatorial regions of Africa and the southeastern United States are prone to drought.

　　In the winter when most La Nina reaches its peak, the cold air that affects our country will appear more frequently. According to statistics, from 1990s to February 2022, in autumn and winter when La Nina appeared, cold air affected China 141 times, of which 27 times reached the level of cold wave.

　　"However, there are many factors that determine the temperature in winter, and La Nina is just one of many factors." Zhou Bing emphasized that the winter temperature in China is not only closely related to the intensity of winter monsoon in East Asia, but also related to factors such as Arctic sea ice, Eurasian snow and atmospheric circulation system. Therefore, although there is a greater probability of cold temperature in La Nina’s winter, it does not mean that there will be cold winter.

　　After 1986, the frequency of "meeting" between La Nina and warm winters increased, among which 1998 and 2020 were strong warm winters. The National Climate Center pointed out in the Forecast of Climate Trends in Winter 2022/2023 and Spring 2023 released on November 3, 2022 that it is expected that the cold air intensity affecting China will be weak in general this winter (December 2022 to February 2023), and the temperature in most parts of the country will be close to the same period of the year or high.

　　Experts from the National Climate Center said that climate prediction is a highly professional scientific research business, which needs to be based on a large number of climate observation data and supported by high-resolution numerical forecasting products, so as to conduct comprehensive judgment and analysis, and finally draw scientific conclusions cautiously.

　　Deron is the warmest garment material at present?

　　Truth: There are many materials similar to its warm-keeping effect.

　　As soon as the weather turns cold, many people begin to buy thermal underwear. Go to the e-commerce platform to search for "thermal underwear", and many products have the words "Derong" on their packages. Derong has almost become the most frequent thermal clothing material this year. Many related businesses claim that Deron can generate heat by itself, and it is the warmest garment material at present.

　　So, what is the truth?

　　"Deron is a transliteration of the English word Dralon, which is an acrylic fiber developed by an international life science group in Germany. The main component is polyacrylonitrile fiber." Xu Lei, an associate professor of tianjin polytechnic university Textile Science and Engineering College, said in an interview with Science and Technology Daily that Deron is not a new thing, and it entered the Chinese market as early as 2011.

　　"Derong’s principle of keeping warm has nothing to do with self-heating, but is mainly related to the thermal conductivity of air." Xu Lei said that the thermal conductivity of an object represents its ability to transfer heat, and the low thermal conductivity of air means that its ability to transfer heat is low, that is, heat is not easily lost, so the more air the fabric can store, the better its warmth retention effect. Deron’s cross-section is double-T-shaped, which not only makes the fabric fluffy and thick, but also enables it to "lock" more still air, thus forming an insulation layer and reducing the heat dissipation of human body.

　　"However, ‘ Deron is the warmest garment material at present ’ The statement is incorrect. " Xu Lei said that although the thermal conductivity of Deron is only 0.05 W/m Kelvin, which is relatively low among thermal insulation materials, there are many materials with similar thermal insulation effects among fiber materials.

　　In addition, the moisture absorption performance of cashmere is also relatively general. In contrast, cashmere material is also very warm, and it is soft, comfortable, hygroscopic and elastic. Another example is the down jacket, whose high bulkiness can also retain a large amount of static air, thus playing a warm role and not easily generating static electricity.

　　Is the frost on persimmon a preservative?

　　Truth: Frost is a natural persimmon frost.

　　Persimmon is a cake-like food made of persimmon, and it is also one of the most anticipated foods in winter. Everyone who has eaten persimmon knows that there is more or less a layer of white powder on persimmon, but most people don’t know what this layer of frost is, so it is circulated on the Internet that it is an artificially added preservative.

　　In this regard, Tian Shufen, a professor from tianjin agricultural university, said in an interview with the Science and Technology Daily that the white frost on persimmon is called persimmon frost, which is a naturally formed icing in the production process of persimmon, and is not a preservative, which is harmless to the human body, and consumers can safely eat it.

　　When making persimmon, you need to peel the persimmon first, and then dry the peeled persimmon. In the process of drying in the sun, persimmon will separate out nutrients such as fructose and glucose. After the water evaporates, these nutrients will gradually accumulate and crystallize, and finally persimmon cream will be formed.

　　"Persimmon cream has the effects of moistening lung, relieving cough, stopping bleeding, promoting fluid production and relieving sore throat, and has certain curative effect on symptoms such as sore throat and cough." Tian Shufen introduced that persimmon cream is rich in vitamin B_2, which also has a certain therapeutic effect on aphtha.

　　Generally speaking, the amount of persimmon cream on the outer layer of persimmon is determined by the temperature and drying time. The colder the weather and the longer the drying time, the sweeter the persimmon will be and the more persimmon cream will be. In the process of storage and transportation, if the ambient temperature rises, persimmon frost may melt and become less, which is what we often call "returning frost".

　　However, consumers don’t need to excessively pursue the amount of persimmon cream. They need to be wary of unscrupulous merchants who artificially sprinkle flour, starch and other substances on persimmon in order to improve the "face value" of persimmon. After artificial "whitening", the persimmon looks even, but as long as it is shaken gently, the white powder on it will fall off, and its taste is not the sweet feeling of persimmon cream.

　　The longer the car is hot in winter, the better?

　　Truth: Overheating a car can damage the engine.

　　Before exercise, people usually warm up in advance in order to reduce the harm caused by exercise. Before a car runs, it also needs a "hot car". Experienced old drivers know that in winter, after the car is started in outdoor low temperature environment, it needs to run at idle speed (make the car engine run in neutral position) for a period of time before driving normally.

　　Recently, however, many people said that the longer the warm-up time is, the better, because it is too cold outdoors in winter, which can make the engine warm up more fully.

　　Does this statement make sense?

　　In this regard, Liu Jun, a teacher from the School of Automotive Engineering of Tianjin Vocational College, said in an interview with the Science and Technology Daily reporter that in winter, due to the low outdoor temperature and poor fuel atomization, it is best to gradually heat up the engine when starting it outdoors, and it is not appropriate to use the engine with accelerated and afterburner, so as to reduce the wear of the engine and improve fuel economy.

　　In addition, under the condition of low temperature, the fluidity of engine oil will decrease and the viscosity will increase, so it is difficult to lubricate the engine quickly. Therefore, it is necessary to warm up the car before driving in winter, but the damage to the car caused by excessive warm-up is not small.

　　"There are two main aspects of the damage to the car when the hot car is too long. First, it will make the engine produce carbon deposit (a burnt substance produced by unsaturated olefin and gum in fuel at high temperature during engine operation), which will further affect its performance, especially shorten the service life of engine spark plugs. Second, in the process of idling, the fuel concentration is high, and idling for a long time will waste fuel, increase pollutant emissions, and increase the workload of three-way catalytic converters and particle traps (OPF). " Liu Jun explained.

　　For pure electric vehicles, Liu Jun reminded that the driving device of electric vehicles is mainly composed of motors, power batteries and control systems, and the energy for driving pure electric vehicles comes from batteries, so there is no hot car problem. However, it should be noted that the hybrid vehicle needs to be warmed up. When its mileage exceeds the cruising range in pure electric mode, it needs to be switched from pure electric mode to fuel mode. At this time, if it is not warmed up, it will also damage the engine. Therefore, in this case, the driver had better warm up the car in fuel mode before driving normally.

Country Garden’s response came.

On June 5th, in response to the news that its Country Garden Venture Capital may sell the equity of Changxin Storage, a memory chip manufacturer, thus raising 2 billion yuan, Country Garden responded to a reporter from China, a brokerage firm, saying that the company is actively considering various strategies aimed at optimizing the asset-liability structure, including carefully evaluating the asset portfolio and exploring potential asset disposal opportunities.

Country Garden is still in difficulties. Due to the failure to publish the 2023 annual report on schedule, Country Garden has suspended trading since April this year. At the same time, Country Garden is also facing a debt liquidation hearing. At present, the Hong Kong High Court has ordered that the petition hearing be postponed until June 11.

Country Garden, which is in trouble, heard the news of disposing of assets.

Some foreign media reported that Country Garden Venture Capital, a subsidiary of Country Garden, is seeking to sell its shares in Changxin Storage Technology Co., Ltd. (referred to as "Changxin Storage"), raising about 2 billion yuan. However, the sale time is still under negotiation, and the final result is inconclusive.

According to official website, Changxin Storage is an integrated memory manufacturing company, focusing on the design, research and development, production and sales of dynamic random access memory chips (DRAM). It is a competitor of Micron Technology and Samsung Electronics. Changxin Storage was founded in 2016. Changxin Storage is headquartered in Hefei, Anhui, and has several R&D centers and branches at home and abroad.

In response to the above news, Country Garden insiders told China, a brokerage firm, that the company is committed to actively exploring various strategies to optimize the asset-liability structure, including prudent assessment of the asset portfolio and potential asset disposal opportunities.

"If there is any substantial progress or specific decision, we will disclose it to the market in a timely manner in accordance with relevant regulations." The above insiders said.

According to Tianyancha information, Country Garden holds 1.6805% of the shares of Changxin Technology Group Co., Ltd. (hereinafter referred to as "Changxin Technology") through the equity investment partnership (limited partnership) of No.5 Huibi, Nanhai District, Foshan City under Country Garden Venture Capital, and the latter holds 100% of the shares of Changxin Storage.

In March this year, the listed company Zhaoyi Innovation (603986.SH) announced that it planned to make a strategic capital increase of 1.5 billion yuan for Changxin Technology. After the capital increase is completed, Zhaoyi Innovation will hold about 1.88% of the equity of Changxin Technology. Before this capital increase, Zhaoyi Innovation held about 0.95% equity of Changxin Technology, which also indicated that the valuation of Changxin Technology may increase from the previous 139.982 billion yuan to 161.29 billion yuan, and Country Garden held more than 2 billion yuan.

Country Garden seeks to save itself from difficulties.

In fact, due to its predicament, it is not surprising that Country Garden sold its equity to cash in funds to save itself.

On June 5th, Country Garden announced that in May this year, the contracted sales attributable to shareholders’ equity of the Company reached 4.29 billion yuan. The contracted sales floor area attributable to shareholders’ equity of the Company is 440,000 square meters.

In the first five months of this year, Country Garden realized the contracted sales attributable to shareholders’ equity of the Company of 21.65 billion yuan, down 80.8% from 112.76 billion yuan in the same period of last year; The contracted sales floor area attributable to shareholders’ equity of the Company was 2.251 million square meters, down 84.39% from 14.42 million square meters in the same period of last year.

On May 13th this year, at the monthly management meeting of Country Garden, Yang Huiyan, chairman of the Board of Directors of Country Garden, said that although the company was experiencing market tests, its balance sheet remained relatively healthy. She revealed that the Group is actively optimizing its asset structure and reducing financial risks to ensure that it can quickly seize opportunities when the market recovers.

Yang Huiyan also said that the policy is gradually improving. As long as we persist in the trough, the real estate industry will surely usher in spring.

Country Garden announced on the Hong Kong Stock Exchange in March this year that it is expected that it will take longer to complete the preparation of the consolidated financial statements for 2023, and it will not be able to publish the annual results for 2023 on schedule. In view of this, Country Garden has been suspended since the beginning of April this year.

Country Garden will also face a liquidation hearing. The petitioner, Ever Credit Limited (Jiantao Group), filed a liquidation petition with the High Court of Hong Kong in February this year due to the unpaid term loan and emergency interest of about HK$ 1.6 billion, and the first hearing was held on May 17.

In May this year, after the two parties went to court, Country Garden applied for an adjournment to prepare more evidence. The two sides subsequently agreed to postpone the case until June 11th.
