On-the-spot report of Jinan waste oil case: 500 tons of fake cooking oil was sold to many provinces, and three brothers were severely punished.

According to the Shandong Provincial People’s Procuratorate, in some rural markets and grain and oil stores, bulk edible oil in plastic barrels will be placed. They are bright in color and cheap, and look the same as the soybean oil we usually eat with the naked eye. They are deeply loved by some catering industries. But can you believe that there is a disgusting truth behind these seemingly excellent bulk oils? Chili, leftovers, duck heads, chicken bones and other kitchen waste are transformed into edible oil by people with ulterior motives and served on people’s tables.

It’s incredible, right? But my friends, these real things are not far away from us. Before 2011, many ordinary people ate this kind of oil.

And this situation continued until the appearance of a tip-off, which tore open a corner of the shady county. The investigation authorities followed the trail and pursued it with all their strength, and finally found that there were more than 7,000 tons of waste oil involved, of which 500 tons were sold as edible oil in Anhui, Liaoning, Henan, Shandong and other places. How is this 500 tons of waste oil produced and sold, swaggered into the market and put on people’s tables? How to guard the safety on the tip of the tongue of ordinary people? Please listen to the story of Sun Ying, deputy director of the investigation and supervision department of Jinan People’s Procuratorate, the most beautiful prosecutor in Qilu.

Part 1

Pingyin is a suburban county in Jinan City, Shandong Province. Pingyin country, known as the tradition of operating oil mills. In September, 2011, a news came that it was like a bombshell between Pingyin and urban areas: there was actually an oil processing factory in the county that had been engaged in the production of waste oil!

In April 2011, under the unified command of the Ministry of Public Security, public security organs in Zhejiang, Shandong, Henan and other places cracked a series of cases in which Jinan wesen Energy Co., Ltd., located in Rose Town, Pingyin County, used waste oil to manufacture and sell edible oil for the first time, destroying the "waste oil" criminal network involving 14 provinces.

When the big case was solved, the investigators finally put their minds at ease. But who would have thought that just three months later, a tip-off letter touched people’s nerves again.

Sun Ying, Deputy Director of the Investigation and Supervision Department of Jinan Municipal People’s Procuratorate:

According to the report letter, there are other oil production enterprises in Pingyin County that are also engaged in the production of waste oil. Reminiscent that when the police asked the product distributor of Green Company, they overheard similar statements. After many investigations, an oil supplier named Yang Chuanqing came into the police’s field of vision.

Who is Yang Chuanqing? Is he also engaged in processing waste oil? All this has to start from the beginning.

Yang Chuanqing is a salesman of Jinan Fada Oil Industry Co., Ltd. located in Guoliugou Village, Kongcun Town, Pingyin County. When it comes to developed companies, we have to say that the rich stars in Guoliugou Village, Kongcun Town-three brothers, Yang Chuanfeng, Yang Chuanbo and Yang Chuanqing.

It is said that brothers are clear about accounts, and no matter how good their feelings are, they can’t do business together. However, the partnership between the three brothers went smoothly. In the early years, they were all born to kill pigs, and later they switched to open flour mills and grain and oil wholesale stores together. In 1999, the three brothers jointly invested, and Yang Chuanfeng registered and established the Guoliugou Village Oil Factory in Kongcun Town, Pingyin County. Over the years, the villagers have never heard of any conflicts between the three brothers because of business, and the enterprise has grown from a small workshop in the countryside to a large factory with three workshops and more than 20 workers.

Part 2

If nothing else, the investigators only inquired about the industrial and commercial registration of their company, and they can almost conclude that the business of the three young brothers is not simple!

Sun Ying, Deputy Director of the Investigation and Supervision Department of Jinan Municipal People’s Procuratorate:

After inquiring about the industrial and commercial registration, it is found that the business scope of developed companies is the production and sales of biodiesel, the acquisition of animal oil, and the sales of industrial oil, fatty acid, oleic acid and stearic acid. There is no edible oil in the company’s business scope, but it sells edible oil to the outside world, which is definitely tricky.

According to a villager’s report to the police, the business of developed companies is very busy: large trailers carrying raw materials from other places are 20 to 30 meters long and full of diesel barrels, and there can be at most five or six vehicles a day. The tankers that come from other places to pull oil usually come at night or Saturday and Sunday.

On July 20, 2011, the police summoned Yang Chuanfeng, the actual person in charge of the developed company. Faced with all kinds of evidence, Yang Chuanfeng, who was already guilty, quickly explained the process of the crime.

Guoliugou Oil Plant is jointly operated by three young brothers. Among them, Yang Chuanfeng is responsible for production, Yang Chuanbo is responsible for staff management and cashier, and Yang Chuanqing is responsible for purchasing and selling. In March 2009, Yang Chuanfeng registered and established Jinan Fada Oil Co., Ltd. on the original basis, and its business scope includes the production and sales of biodiesel, the purchase of animal oil and the sales of industrial fatty acids, oleic acid and stearic acid.

At first, the three young brothers were more disciplined, mainly producing oleic acid, stearic acid and vegetable asphalt for industrial use. In order to reduce the cost, under the temptation of huge economic benefits, they used their crooked brains.

According to the industry standard of feed-grade mixed oil, they have no license to produce feed oil and no relevant certificate. But with luck, in order to make more money, the three brothers still took the risk of breaking the law and used hogwash fat to produce feed oil used in feed processing, and then sold it to a feed factory in the name of soybean oil. By 2011, they had purchased raw materials such as hogwash fat and clay from Beijing, Sichuan, Tianjin, Liaocheng, Tai ‘an and Inner Mongolia, and processed and produced more than 7,000 tons of feed oil, involving more than 56 million yuan.

According to Dou Mou, a worker in a developed company, hogwash fat, the raw material for producing feed oil, is mostly purchased from a Beijing dealer specializing in selling hogwash fat, which is mixed with garbage such as peppers, vegetable leaves, duck heads and chicken heads. The color of the produced feed oil is similar to that of soybean oil, yellow and odorless.

Part 3

People’s hearts are insufficient, and it is difficult to fill their wants. Seeing that there has been no accident in secretly producing feed oil for several years, the Yang brothers began to play the idea of cooking oil again.

"Some people came to our factory to buy feed oil. I knew at a glance that he bought feed oil and went back to sell it as edible oil. But he won’t talk, and I won’t ask. We both know each other. In addition, from my years of experience, the other party sells edible oil, and some cars are printed with the words "special vehicle for edible oil". Although Yang Chuanfeng knew that it was risky to sell it to them, after a period of time, he found that nothing happened, so he arranged for his younger brother Yang Chuanqing, who was in charge of product sales, to sell waste oil which was much cheaper than the market price in Jinan and Liaocheng in the province and Shanxi and Hebei outside the province.

In 2009, after Yang Chuanfeng changed suppliers and improved technology, the price of feed oleic acid was low, which was not much different from that of edible oil in color, smell, consistency and solidification temperature. It was difficult to distinguish it from edible oil simply by observation, so they began to boldly sell the inferior oil originally used to add to pig feed as edible oil.

Sun Ying, Deputy Director of the Investigation and Supervision Department of Jinan Municipal People’s Procuratorate:

According to Yang Chuanfeng’s account, the raw materials for the company’s production are shipped from Beijing, Sichuan, Tianjin, Shandong and other places, and most of them are refined from the leftovers of restaurants, and some of them are refined from the discarded oil of fried foods and animal fats. The raw materials of gutter oil factory are called "crude oil" by the industry. The refining site of crude oil is generally extremely dirty. The crude oil is heated to 100 degrees Celsius by a boiler to evaporate water, and then clay is added to absorb impurities in the oil and lighten the color. After deodorization, filtration, deacidification and degreasing, industrial fatty oil and defatted oil that can be added as feed are finally produced.

The three Yang brothers’ industries are getting bigger and bigger, and their profits are also considerable: in 2011, the purchased crude oil was more than 5,000-6,000 yuan per ton, the sales price of red oil was about 8,300 yuan per ton, the production loss per ton of red oil was about that of 800 yuan, and the production cost was about 600 yuan. Processing one ton of crude oil could earn about 500-600 yuan.

Investigators extracted seven oil samples from the oil storage tanks in the developed company’s hospital and sent them to Beijing Food Safety Monitoring Center for inspection. After identification, the oil for inspection contains polycyclic aromatic hydrocarbons; Some oil products have excessive acid value, peroxide, high cholesterol and high conductivity. Among them, polycyclic aromatic hydrocarbons (PAHs) are listed as carcinogens by the International Center for Research on Cancer, which may cause cancer if consumed seriously for a long time; If the acid value and peroxide value exceed the standard, aldehydes, ketones and acids produced by oxidation will destroy the digestive tract of human body.

Even such huge profits did not fill the desire of the three young brothers.

Because the purchased hogwash fat has no special invoices for input value-added tax, it is necessary to issue special invoices for output value-added tax to the other party when selling oleic acid and stearic acid products. In order to deduct the tax, the defendant Yang Chuanqing signed a false contract with 11 companies in Shandong and Shanghai through an intermediary in the name of a developed company without actual purchase and sale business, and asked the other party to issue special invoices for value-added tax to the developed company, helping the developed company to obtain 53 special invoices for input value-added tax, with a total amount of more than 3 million yuan and a total tax amount of more than 1.7 million yuan.

Part 4

Due to the long-term operation of developed companies, the criminal means are more secretive, especially the source and sales destination of raw materials are wide and large, involving many provinces and cities across the country. In the process of investigation, it is very difficult for criminal suspects to destroy and hide the evidence involved.

Sun Ying, Deputy Director of the Investigation and Supervision Department of Jinan Municipal People’s Procuratorate:

In order to grasp the key nodes and the main direction of attack, we have invited the relevant departments of the Provincial Animal Husbandry Bureau, the Municipal Bureau of Quality Supervision and the national experts in grain, oil and chemical industry to inspect the production plants of the units involved. According to the relevant production equipment and processes, it is analyzed that the production lines and production processes of developed companies are far beyond the production scope of industrial and commercial registration, and they all have the ability and characteristics to produce a large number of "gutter edible oil".

After a period of understanding and examination, prosecutors agreed that almost all the problems in this case, such as legal application, amount determination, subjective aspects, criminal evidence, judicial expertise, etc., revolved around one theme-qualitative. The qualitative problem of the case runs through the whole litigation process and becomes the key point of the success or failure of the case.

Sun Ying, Deputy Director of the Investigation and Supervision Department of Jinan Municipal People’s Procuratorate:

In 2011, the processing and sale of "cooking oil in gutter" was in the gray area of legislation, lacking clear legal basis and testing standards. With the in-depth investigation, various problems gradually emerged, mainly as follows: it is difficult to obtain evidence, and the company’s sales "off-line" involves 17 commercial, grain and oil enterprises in many provinces, and the verification workload and difficulty are extremely great; It is difficult to determine the nature. There is no precedent for determining the crime of producing and selling food that does not meet the safety standards in China, and the evidence system and specifications for determining the facts of the crime need to be further reached.

The final flow direction and actual harm of oil are very important to determine the nature of the case. In order to form a solid and strict evidence chain, the prosecutor has made sufficient preparations.

Sun Ying, Deputy Director of the Investigation and Supervision Department of Jinan Municipal People’s Procuratorate:

On the basis of mastering a large number of criminal facts about the company, we sealed up a grain and oil industrial company in Liaocheng, which bought "gutter oil" from a developed company and sold it as cottonseed oil to food processing vendors, and arrested the company’s person in charge and accountant, as well as the manager and driver of a company in Jinan. The seizure of the above-mentioned company personnel has played a key role in clarifying the production and sales network.

The case was decided on January 7, 2014. Defendant Yang Chuanfeng was sentenced to death, suspended for two years, deprived of political rights for life, and confiscated all personal property; Yang Chuanqing and Yang Chuanbo were sentenced to life imprisonment, deprived of political rights for life, and confiscated all personal property. Other defendants in this case were sentenced to fixed-term imprisonment ranging from 15 years to 5 years.

After the defendant refused to accept the appeal, the Jinan Intermediate People’s Court formed a collegiate bench according to law. After reading the papers, interrogating the appellant and listening to the opinions of the defenders, it considered that the facts of the case were clear, dismissed the appeal and upheld the original judgment.

Sun Ying, Deputy Director of the Investigation and Supervision Department of Jinan Municipal People’s Procuratorate:

In the case of gutter oil detected by the police, the industrial upgrading of gutter oil production and sales from small workshops to large factories reflects the lack of supervision mechanism and measures. In the past, China’s food safety was supervised according to the territory, and cross-regional supervision in many places basically became no matter who. Once the waste oil industry chain puts different links in different regions, such as purchasing crude oil from Sichuan, Zhejiang and other places, deep processing in Shandong and other places, and selling it to Henan and other places, the supervision of "cleaning the snow before the door" will lose its effect.

It has been more than four years since the case was filed again, because the social environment and legal environment in which the case was handled, the puzzles and problems it faced, are still of typical significance in this ever-changing period when the rule of law is in urgent need of perfection. As the prosecutor said in the court statement: "Food producers should engage in this industry with their conscience, not only for the sake of not being punished by punishment, but also for the healthy operation of the whole society and the happy life of their future generations …"

Knowledge: What you should know about the Middle East.

Xinhuanet Beijing, January 19th When it comes to the Middle East, your first reaction is … chaos? Indeed, the Middle East gives people the impression that it is chaotic: there are many wars, many problems and many concepts … These tangled chaos in the Middle East are really the "news spots" that the media like to report, but is "chaos" really the whole of the Middle East? Of course not!

What you see and hear may be true, but it may not be comprehensive. Besides, American and western media are still dominant in the world, and what they tell you may not be true.

So, what is the real Middle East like? Ordinary foreigners who have worked and lived in the Middle East will tell you this: a long history, splendid civilization, rich products, simple people … The mosque in Saudi Mecca is solemn and sacred, the Egyptian pyramids and the Nile River shine brightly, the bazaar in Tehran, Iran is busy and lively, street vendors, mysterious robes, exotic music and dances, lush date palm groves … where tranquility and noise are intertwined, and tradition and modernity are combined.

The picture shows tourists riding camels to visit the pyramids in Cairo, the capital of Egypt.

The Middle East is "chaotic", but the disputes and conflicts between Syria, Iraq, Yemen and Palestine and Israel are only partial and few. Most parts of the Middle East are not chaotic, where there is a basic production and living order in a normal country, and ordinary people should eat, drink and lead a normal life …

Understand the "chaos" and "no chaos" in the Middle East. Under this basic understanding, let’s discuss what is the correct way to understand the Middle East. First of all, we must understand some concepts.

Middle East

First of all, the Middle East is a generalized geographical concept, specifically referring to most parts of West Asia and North Africa.

Most of the Middle East is Islamic countries, except Israel and Cyprus. The Middle East is mostly Arab countries, except Turkey, Iran, Israel and Cyprus. Therefore, the words Middle East, Arab countries and Islamic countries cannot be equated.

Next, the conceptual misunderstandings that are easy to get around are popular.

[Islamic countries and Arab countries]

Islamic countries, also known as Muslim countries, refer to countries and regions where Islam is the national religion and most residents believe in Islam. Muslims are people who believe in Islam. Both Islam and Muslims are transliterated in Arabic with the same root.

Arab countries refer to countries dominated by Arab peoples. The people mainly speak Arabic and believe in Islam, and have similar cultures and customs. Arab countries are mainly distributed in West Asia and North Africa, that is, the Middle East.

The picture shows the Babel of the Great Mosque in Samarra, Iraq.

To put it simply, Middle Eastern countries are divided by geography, Islamic countries are divided by religion, and Arab countries are divided by ethnicity. The Middle East is mainly Arab countries, and the Arab nation mainly believes in Islam, and Islam spreads in the world, not only in the Middle East and Arab nations, so Islamic countries are more widely distributed.

Understand the above concepts, you can immediately understand what is the Organization of Islamic Cooperation and the League of Arab States. The former is an international organization composed of Islamic countries, and the latter is a regional international organization composed of Arab countries.

The picture shows the scene of the GCC summit in Riyadh, Saudi Arabia, on December 10th, 2015.

There is also the Cooperation Council for the Arab States of the Gulf (GCC), which, as its name implies, is the main organization of Arab countries in the Gulf region. The Gulf here refers to the Na Pianhai between Iran and Arabian Peninsula. The "Gulf" of the Gulf War refers to it. Iran calls it Persian Gulf, and Arabs call it Arabian Gulf. It can be seen that there are many stories about the Gulf.

Ethnic group

In all the concepts mentioned above, ethnic and religious issues can’t be avoided. Let’s increase our knowledge immediately.

The main ethnic groups in the Middle East are Arabs, Persians, Jews and Turks. They all have their own countries, namely Arab countries, Iran, Israel and Turkey. There is also a relatively large ethnic group, Kurds, but they do not have their own country, mainly scattered in many countries in the Middle East.

From history to reality, the harmonious coexistence of these major ethnic groups is the mainstream, and there are different degrees of grievances in different periods, so ethnic contradictions are one of the reasons for the chaos in the Middle East.

[Islam]

People in the Middle East mainly believe in Islam, Judaism and Christianity, and Jerusalem is the holy land of the three major religions in the world. Religious issues have always hampered the history and present of the Middle East, both within and outside the region.

We mainly talk about Islam, the main religion in the Middle East.

Islam means "obedience" and "peace", and its meaning shows that Islam advocates peace, which can also be seen from the green color in the national flags of many Islamic countries.

The picture shows pilgrims praying at Mount Arafat in Mecca, Saudi Arabia, on September 23, 2015.

Islam obeys and believes in Allah, while the Prophet Muhammad is said to have accepted "enlightenment" and "been ordained to be holy" to carry out the "mission" given by Allah, spreading Islam and making it the dominant position in the Arabian Peninsula at that time. Muhammad is actually equivalent to a great missionary.

While preaching, Muhammad was also a politician. At the end of 631 AD, he completed the political unification of Arabian Peninsula, and all tribes converted to Islam one after another, and also recognized his leadership. He established a political power that combines politics and religion. Therefore, Muhammad is both a religious leader and a political leader.

[Shiites and Sunnis]

Speaking of which, it’s time to explain the sectarian problem. After Muhammad’s death, there have been two major factions of Islam, Sunni and Shia. The main difference between them lies in who is the legal heir of Muhammad. This is both a religious issue and a political issue. Simply put, who should inherit power.

Shiites believe that only Muhammad’s son-in-law and cousin Ali and his direct descendants (that is, Muhammad Hashemite family) are the legal heirs, while Sunnis believe that the caliph (meaning heir) is the legal heir and the leader of Islamic politics and religion.

The picture shows a mosque in southern Tehran, Iran.

Over the past 1000 years, these two factions have met each other at war and lived in harmony for a long time. It was not until modern times that the sectarian problem became prominent and sharp because of the intervention of western powers in the Middle East.

Sunnis are the largest, accounting for more than 80% of Muslims in the world. Shiites are mainly distributed in Iran, Iraq, Syria, Bahrain and other countries. Iran, Iraq and Syria are the only Shia countries in the world.

There are so many differences between countries in the Middle East, and the most basic difference is the political system. Some are monarchies such as Saudi Arabia, and some are constitutional monarchies such as Kuwait and Jordan. Some are parliamentary republics, such as Turkey and Israel. Some are presidential republics, such as Egypt and Lebanon.

Petroleum

There is another important reason for the turmoil in the Middle East, besides the geopolitical game of external forces and the internal ethnic, sectarian and institutional factors, and that is oil. It took about a hundred years for the Middle East to be rich in oil, which not only produced great wealth, but also made the West covet it, which brought great troubles to the Middle East’s politics and economy.

It is true that the Middle East is called the "world oil depot". Among the top ten countries in the world in terms of crude oil reserves, five countries are recognized as coming from the Middle East, of which Saudi Arabia accounts for about 20%, ranking first in the world, and Iran, Iraq, Kuwait and the United Arab Emirates each account for about 10%.

Two-thirds of the members of the Organization of Petroleum Exporting Countries (OPEC) come from the Middle East. The changes in the output and export volume of these countries have a great impact on the world market and oil prices, which can be called the "wind vane" for observing the world oil market.

Any trouble in the major oil producing countries in the Middle East immediately affects the nerves of the world oil market. This can explain why any policy actions taken by the West towards the Middle East will make a huge noise in the oil market, such as the Iraq war, sanctions against Iran, and the turmoil in West Asia and North Africa, which have all triggered violent reactions in the world oil market.

High temperature yellow warning! Many places in China are "hot".

Since July 6, affected by high temperature, many places in China are in full swing, with high temperature above 35℃ in many provinces. At 8: 30 on July 8, China Meteorological Bureau launched a four-level emergency response to major meteorological disasters (high temperature).

Which areas are specifically affected by this round of high temperature process? How will the high temperature trend develop in the future? What are the defense suggestions? Fu Jiaolan, chief forecaster of the Central Meteorological Observatory and senior engineer at the research level, interprets them one by one.

High temperature above 35℃ occurred in 18 provinces (autonomous regions and municipalities).

The actual situation in the past few days shows that high temperature weather above 35℃ has occurred in parts of southern Xinjiang basin, eastern northwest, northern China, eastern southwest, Huanghuai, Jianghan, Jianghuai and eastern Jiangnan.

Fu Jiaolan introduced that since July 6, a total of 18 provinces (autonomous regions and municipalities) have experienced high temperature above 35 C, mainly distributed in Xinjiang Nanjiang Basin, central and western Inner Mongolia, Gansu, northeastern Qinghai, Ningxia, Shaanxi, central and southern Shanxi, Tianjin, central and southern Hebei, Henan, Shandong, Sichuan, western Hubei, Anhui, Jiangsu, Zhejiang, Shanghai and Fujian. Among them, the daily maximum temperature in some areas of Ningxia, central and western Gansu, central and western Inner Mongolia, central and southern Shaanxi, southern Hebei, western Henan, Sichuan Basin, central and eastern Zhejiang, Shanghai and southern Jiangsu even reached 37℃ to 39℃, and the local maximum temperature in Sichuan Basin, Shaanxi Guanzhong Plain, Hanzhong Plain and Ankang Basin exceeded 40℃. Fu Jiaolan said that the daily maximum temperature in Gansu, Ningxia, northeastern Qinghai, southwestern Shaanxi and Sichuan Basin has exceeded or reached the historical extreme value in the same period.

Precipitation will ease the high temperature in the north and the high temperature in the south will continue

On July 9, the Central Meteorological Observatory continued to issue a yellow warning of high temperature. It is expected that the high temperature in the above areas will continue, and the temperature in some areas will remain above 35 C.

So, how will the high temperature trend develop in the future? Is most of China still the "site" of subtropical high?

In this regard, Fu Jiaolan analyzed that from July 9 to 10, there were still high temperature weather in Xinjiang Nanjiang Basin, western Inner Mongolia, south-central Shaanxi, southern North China, Huanghuai and other places. After 11th, the high pressure in Iran has obviously weakened, and there will be a heavy precipitation process in northern China, which can alleviate the impact of this round of high temperature on the north.

However, in the next 10 days, the subtropical high will further extend to the west and lift to the north, controlling most of southern China. The high temperature weather in the south will further develop, and there will be continuous high temperature sunny and hot weather in the eastern part of southwest China, Jianghan, Jianghuai, Jiangnan and northern South China. Among them, the local temperature in Sichuan Basin and Zhejiang can reach above 40 C.

High temperature defense measures are indispensable.

In view of the current high temperature weather in many places in China, Fu Jiaolan said that high temperature weather will have adverse effects on power supply, water resources allocation, human health and agricultural production, especially in the middle and lower reaches of the Yangtze River and Sichuan Basin, where continuous high temperature weather occurs, attention should be paid to relevant preventive work. At the same time, Inner Mongolia, Shaanxi, Henan and other places also need to prevent the adverse effects of high temperature weather.

At present, it is the summer vacation. Fu Jiaolan reminds parents and students that if they have travel plans, they need to take measures to prevent heatstroke, guard against heatstroke, pay attention to weather forecast and early warning information in time, and make reasonable arrangements for travel.

Runze Technology has been investigated by 84 institutions: at present, the maximum air cooling capacity of the company can be more than 40KW, and the company will mainly deliver high-power cabinets in

  () The Record Form of Investor Relations Activities was released on January 30, and the company was investigated by 84 institutions on January 29, 2024. The types of institutions are QFII, insurance companies, others, fund companies, overseas institutions, securities companies and Sunshine private equity institutions. The main contents of investor relations activities are introduced: 

  I. Ms. Shen Jingwei, the director and secretary of the company, introduced the overall situation of the company in 2023. Dear investors, good evening, I am Shen Jingwei, secretary of Runze Technology. Thank the Changjiang team for organizing this meeting for us, and welcome everyone to attend the 2023 annual performance forecast exchange meeting tonight. In the last month, the market expectation was weak, and there were many market corrections, but we are still full of confidence in the market, and we also cheer everyone up. I hope everyone will have confidence. The company has been deeply involved in the field of digital economy for 15 years, and has always insisted on continuous and large-scale investment in the fields of intelligent computing power and computing power infrastructure. Although the competition in the data center industry was fierce in the past year, it was also the biggest opportunity in the data center industry in the past decade. In the industry, we think that 2023 is the "first year of liquid cooling" and also the "first year of intelligent calculation". In terms of technology, the power of single cabinet in the market has jumped, and new liquid cooling technology has been gradually applied. In terms of demand, there are large AI artificial intelligence model customers in the market, and the demand is growing very fast. Let me briefly talk to you about the latest performance of the company in 2023. Financially, the company achieved a net profit of 1.75-1.85 billion yuan in 2023, a year-on-year increase of 46.05%-54.39%; The net profit after deducting non-homecoming was 1.74-1.84 billion yuan, a year-on-year increase of 52.91%-61.70%. Since its establishment in 2009, the company has always adhered to the super-large-scale park-level model, and has been in the early stage of investment loss for the first ten years.In 2019, it began to make a profit, and in that year, it realized a net profit of 108 million yuan, which was not returned to the mother. Up to now, it has achieved rapid growth for four consecutive years, with a compound annual growth rate of 100.26%-103.08%. Business: 2023 is a very important milestone year for the company. Before 2022, all the company’s income came from Langfang Park. In 2023, foreign parks were put into operation one after another, and the company officially entered a new stage of contributing income from one park to three parks. In 2023, the company delivered five new data centers, three from Langfang, one from the Yangtze River Delta and one from Guangdong-Hong Kong-Macao Greater Bay Area, with a total delivery of about 3w cabinets. By the end of 2023, the company had delivered 13 data centers and nearly 8w cabinets, and the number of cabinets delivered increased by 65.22% compared with the end of 2022. In addition to the rapid growth in the number of deliveries, the cabinet power delivered by the company in combination with market demand in 2023 has also been greatly improved compared with previous years. In 2023, the company delivered the whole pure liquid-cooled intelligent computing center with a single cabinet power of 21.5KW and the high-density air-cooled data center with a single cabinet power of 10.5KW, and gradually upgraded the low-power cabinets in Langfang Park. In terms of shelving rate, the original data center still maintains a high shelving rate, and the shelving speed of the newly delivered data center is in line with expectations, with the shelving speed of liquid cooling and high-density air cooling reaching the best level in history. The stable operation of the original data center and the gradual delivery of the new data center provide a stable profit source and cash flow increment for the company’s performance development.Power supply: The company’s self-built 220KV substation was put into operation this month. The substation is very high in configuration, with a total capacity of 4 * 240,000 KVA transformers, and the maximum power supply is as high as 960MW. The power supply of the whole Langfang Park is directly increased by more than 2 times, which can at least meet the rapid development of Langfang Park in the next five years and provide the most powerful guarantee for the company to undertake the growing demand of digital economy industry in Beijing, Tianjin and Hebei. New business of AIDC Intelligent Computing Center: In 2023, the company delivered the first pure liquid-cooled intelligent computing center in the industry. With a deep customer trust foundation, the company established a strong first-Mover advantage and accumulated rich experience in the design, research and development, construction and operation and maintenance of liquid-cooled intelligent computing centers. Benefiting from the rapid growth of demand for intelligent computing driven by the application of liquid cooling solutions and the outbreak of AI artificial intelligence, the company is cooperating with its ecological partners in the industry, Qi Xin, to deploy large-scale computing modules. The large team has the full link delivery capability of computing modules and the technical level is leading in the industry. New layout: 2023 is the third year for the company to acquire resources, and it is located in Danzhou, Hainan, with an overall planning of about 30,000 cabinets.

  Second, investors are more concerned about the issue

  Q: The performance has exceeded the market expectation. What about the traditional IDC customers, customer structure and the proportion of head manufacturers?

  A: There is no essential change in the customer structure of the traditional IDC business, but the main change is the increase in the power of the delivered single cabinet. At present, the market demand for high-power cabinets is relatively strong, and the demand for cabinets below 5KW is gradually shrinking. Therefore, the shelves of high-power air-cooled and ultra-high-power liquid-cooled cabinets delivered by our mainstream in 2023 are very fast.

  Q: What is the current market competition pattern? What is the market demand and when will the inflection point appear?

  A: First of all, let’s limit the scope: first-tier cities and surrounding areas. 2023 is the most competitive year for traditional IDC. On the supply side, the market is constantly clearing out, even if it has not reached the inflection point, it is approaching the inflection point. This can refer to whether the shelf rate of first-tier cities is improving. If the improvement indicates that the inflection point has appeared; On the price side: In 2023, there were many large-scale accidents in Internet companies, cloud vendors and even financial industries all over the country, which will force end customers to pay more attention to the quality of service and the price will improve. Therefore, we judge that the inflection point of first-tier cities, whether on the left or on the right, is very close to the current time. Secondly, let’s talk about the current market situation. There are three types of cabinets in the market: traditional IDC rooms, modern IDC rooms and future AIDC rooms. Traditional IDC computer room: mainly produced in 2016 -2019, this kind of cabinets seized the dividend of the rapid development of mobile Internet. At that time, the market was in short supply, and the cost was recovered very early and the profit was realized. The characteristics of this kind of computer room are: small scattered points and average overall quality. At present, the difficulties are: after the servers that were put on the shelves gradually expired in 2017 -2019, they were continuously put off the shelves. Due to the small scale, high PUE and difficult transformation of such computer rooms, the head Internet or cloud vendors will not return their rents after they are taken off the shelves. They are under great pressure to take off the shelves and also face great transformation pressure. Modern IDC computer room: mainly produced in 2021 -2023,Due to the shortage of traditional IDC computer rooms before 2019, and the encouragement of new infrastructure at that time, many new market entrants poured into the industry, and this part of computer rooms were put into the market one after another in 2021, resulting in short-term oversupply in the market. With the introduction of policies such as "double carbon" and "calculating from the east to the west", the supply balance was alleviated to some extent. Due to centralized supply, and the traditional computer room has recovered its cost, it is also constantly reducing its price. At present, this kind of computer room is facing a low shelf rate and is in a difficult stage of recovering its cost. The future AIDC computer room was mainly produced in 2023. Due to the rapid outbreak of AI demand, the market put forward higher requirements for computing power per unit area. Now the IDC computer room can’t meet the transformation needs of AIDC. At the same time, AIDC needs multi-parties to participate in the planning and design, which is technically difficult and the investment scale is relatively large. Because the existing IDC participants were injured in previous years, their overall participation enthusiasm is not high. On the contrary, there are more cross-border participants, but the future AIDC computer room needs more. Let’s talk about our situation again. Since its establishment, Runze Technology has been focusing on ultra-large-scale park-level data centers, and there is no pressure on the removal of traditional IDC rooms. At the same time, the company actively controlled the delivery pace. The early delivery rate of eight modern IDC rooms exceeded 90%, so it has the resources, technology and strength to develop AIDC rooms. Regarding the market demand, it is divided into two parts: 1. As for the general server, because the market traffic is still increasing,The total number of servers in the overall market is still increasing. Although the growth rate of server demand is declining due to various capital expenditure plans, some new large-scale bidding orders can still be seen in the open market. 2. In terms of high-performance servers, AI broke out in February 2023, when the market was in a wait-and-see state. In the second half of the year, the market began to really invest. At present, the overall investment of customers who insist on making large models is not small, and foreign large models are also developing rapidly. Although domestic chips are limited to some extent and the development speed is also very fast, we should have full confidence in domestic related manufacturers.

  Q: What is the difference between traditional IDC services and AIDC services? Is AIDC technically difficult?

  A: Traditional IDC mainly serves general-purpose servers, that is, traditional X86CPU servers. Traditional IDC mainly focuses on how many basic resources we have, how many cabinets we can build and how many servers we can carry from the perspective of our own resources. AIDC business mainly serves high-performance servers, that is, GPU servers. AIDC mainly focuses on how much computing power the customer requires per square meter to provide and how large a computing power cluster to build. Therefore, the whole building of AIDC is equivalent to a super server. AIDC manufacturers need to organize the design of the internal architecture of this super server, and at the same time, they need to pay attention to "short distance", "high density", "high speed", "network architecture" and "expanding resources". I’ll give you some concrete technical examples. A computing POD is 64 high-performance servers, which is a layer of network. The two-tier network is spine-leaf. According to the calculation of 8 high-performance servers with a single port of 400G, the two-tier network of high-performance switches can interconnect 256 high-performance servers, and the three-tier network is core-spine-leaf, which can interconnect 8192 high-performance servers at the maximum. At the same time, the power demand of a high-performance server is 10KW, which also puts very high demands on the cabinet side. Therefore, it is very difficult to achieve such a large cluster interconnection. At present, there are very few manufacturers in the market who have built a three-tier network architecture.However, our joint ecological partners belong to a few who can do it, whether it is IB networking or RoCE networking. In addition, with regard to the delivery of large clusters, it is the first step to have equipment, but also to be able to buy enough auxiliary materials (cables and modules) to understand the track optimization of IB network. At the same time, it has the debugging ability of IB network, the tuning ability of server side, the understanding of large model communication library, and even the need to write monitoring software. Many factors are superimposed to have the full link delivery ability of large clusters, and even large manufacturers generally have their own "disassembly, modification and distribution" workshops. Because the motherboard design ideas of different brands of servers are different, when the same cluster involves multiple brands and specifications, it needs to be configured in a unified way. At this time, a "disassembly and assembly" workshop is needed to carry out standardization operation to improve efficiency, and at the same time, it is necessary to understand the motherboard design topology of different models of server manufacturers in order to facilitate the optimization of large clusters. It is difficult for any single manufacturer to do these things. We have also combined with many eco-partners. Qi Xin worked together to build a computing module to understand these things. Our technology and resources in this area are in the leading position in the industry.

  Q: What is the revenue and net profit of IDC business and AIDC business in 2023? Why did the actual profit in 2023 communicate better than that in the performance briefing of the third quarterly report, and what part of the contribution mainly came from?

  A: In 2023, the company’s operating income was about 4.4 billion yuan, of which AIDC business was less than 1 billion yuan, including our liquid cooling business and intelligent computing related business. Due to more company deliveries this year, the gross profit margin and net profit margin of traditional IDC business have been affected. The overall gross profit margin of AIDC business is about 40%, but it has developed rapidly. The actual profit in 2023 was better than that in the performance briefing of the third quarterly report, mainly due to the rapid growth of demand for intelligent computing driven by the application of liquid cooling solutions and the outbreak of AI artificial intelligence, the smooth expansion of new AIDC-related businesses and the continuous expansion of corresponding revenue scale.

  Q: What is the future delivery plan communicated with customers and the future capital expenditure?

  A: Our business model is based on sales and production. At present, there are still 4-5 data centers under construction in China. If customers have a clear demand for new orders, the company can complete the delivery quickly and need some new capital expenditure. Since the second half of 2023, the company has felt that the demand for AIDC business is relatively strong, so Heping Lake in Langfang Area B is planned according to AIDC mode. The company’s Langfang A data center has grasped the wave of mobile Internet in 2016-2019 and achieved good development. Pinghu, Zhejiang plans to become an intelligent computing center, hoping to seize the opportunity of AI development. At present, this piece of progress is relatively smooth, and it has also achieved a certain market position and popularity. The local government has also given some basic resources support. At present, the company has also established a stable ecological partnership with end customers, network cards, switches, servers and other manufacturers, and jointly completed the design of AIDC computer room. Business development stems from design, and design promotes customer strategy, which has formed a benign positive cycle.

  Q: The specific composition of the company’s business, the removal of traditional IDC friends, and the company’s leaseback.

  A: In 2022, the company’s traditional IDC business income was 2.7 billion, and in 2023, the traditional IDC business income was about 3.5 billion, an increase of 30%. The increase mainly came from: two buildings were full this year, and two new traditional buildings were added, and the shelves were not bad. During the reporting period, the company took the initiative to speed up the upgrading of low-power cabinets. The power of cabinets delivered in the early stage was mainly 4.4KW. At the end of the service of the servers carried by the aforementioned low-power cabinets, the company quickly upgraded them. At present, some low-power cabinets have been upgraded and have begun to be rented back. AIDC business mainly includes liquid cooling and intelligent calculation business.

  Q: What is the synergy between AIDC business and traditional customers? How many traditional customers have been introduced into AIDC business? How many AIDC customers are waist customers? How long is the signing span of AIDC business?

  A: Big model customers need computing power, algorithms and data. At present, there are mainly two types of customers in the market, one is large Internet companies and cloud vendors, and the other is entrepreneurial AI model companies, which is what everyone calls waist customers. We think that 2023 is the "first year of smart calculation". After another 3-5 years, waist customers will run out of great companies. Regarding the types of customers, we have signed a strict confidentiality agreement with our customers, and even the company will give customers a code name, so it is not convenient to say too much.

  Q: How to predict the company’s performance in 2024, and are you confident in the completion of its performance commitment in 2024?

  A: The company is full of confidence in its performance in 2024 and more confident in its performance commitment in 2024. In 2024, the company will continue to take the differentiation strategy: first, in terms of traditional IDC business, the company will mainly supply high-power cabinets that are scarce in the market in the future. The five data centers delivered in 2023 will continue to steadily increase the shelf rate in 2024, and make steady contributions to the performance together with the original eight data centers. Second, in terms of AIDC business, many AIDC customers of the company are growing sturdily and the demand for AIDC is increasing. Therefore, the company will continue to cooperate with ecological partners to the greatest extent, create an ecological circle of computing power, provide the most effective computing power, and then obtain business orders from the reasoning side with a larger market scale. Third, in 2024, the company will still combine the market demand and gradually deliver multiple data centers in Beijing-Tianjin-Hebei, Yangtze River Delta, Chengdu-Chongqing, Guangdong, Hong Kong and Macao to meet more customer needs and steadily improve the company’s performance.

  Q: Is Foshan IDC or AIDC?

  A: The first building delivered by Foshan is still a traditional data center, and there are also customers communicating, which can be transformed according to customer needs. AIDC is also an important development direction in the future.

  Q: What is the progress and shelf rate outside Langfang?

  A: Pinghu was put on the shelves slowly in the first three months, but now it is put on the shelves quickly. Foshan just delivered it at the end of the year, and the early stage is in the running-in stage, which is also in line with the company’s expectations. At present, the time is short and there is no reference.

  Q: What is the trend of AIDC gross profit margin?

  A: There was no AIDC business in previous years.

  Q: What is the proportion of high-power cabinets in 2024?

  A: Langfang Area B and Pinghu Phase II are both planned by the Intelligent Computing Center. In addition to high-power liquid cooling, at present, the company’s air cooling can be up to 40KW, and the company will mainly deliver high-power cabinets in the future, and the lowest power delivered in the future can also be 7KW, and the low power will be mainly used as cache nodes.

  Q: Will the structure of IDC and AIDC change further in 2024? Will it maintain a steady year-on-year growth in 2024?

  A: The traditional IDC business will continue to grow steadily. AIDC is not easy to predict. On the one hand, supply will affect business development, and on the other hand, the outbreak time of AIDC application side is uncertain. If it breaks out, the growth will be very rapid.

  Q: What is the company’s dividend expectation?

  A: At present, the company’s dividends are relatively stable, and it is also actively giving back to institutional shareholders and small and medium investors. The specific plan needs to wait until the annual board of directors puts forward a plan;

Focusing on the future industry, leading the layout of synthetic biology and new quality productivity Tianjin University established the College of Synthetic Biology and Biomanufacturing.

On May 15th, 2021, the Tianwen-1 lander landed in the southern part of the Utopia Plain of Mars. "Steady!" Jiang Mingjing, who stood in front of the TV, saw the news and stood up from his chair excitedly, holding his fist and cheering.

This report three months ago gave the reporter the idea of interviewing Professor Jiang Mingjing from the School of Architecture and Engineering of Tianjin University. During these three months, the reporter contacted him many times. As a result, Professor Jiang was either on a business trip or on his way. The background of several calls was the voice of the plane broadcast urging him to turn off his mobile phone. Professor Jiang’s busyness made reporters both surprised and helpless, and even had the idea of giving up the interview. Finally, these days, Professor Jiang returned to Tianjin to tutor graduate students, and the reporter seized this "hard-won" opportunity.

According to the report, in order to make Tianwen-1 land smoothly, Jiang Mingjing and his team spent two years simulating the construction of a Mars surface in Huailai County, Hebei Province. Mars, which is tens of millions of kilometers away from the earth, is an unknown field that needs to be explored urgently. It sounds impossible to "move" it to the earth, but Jiang Mingjing succeeded.

"My major is studying’ soil’, and all kinds of’ difficult soil’, such as Mars’ soil, are actually only a small part of my research content." Jiang Mingjing, a native of Jiangsu Province, speaks an authentic "soft language of Wu Nong". It never occurred to him that the tenderness and delicacy of the water towns in the south of the Yangtze River cultivated such a "hard-core" professor who was willing to deal with clods and stones.

"I studied undergraduate in 1982 and have been engaged in geotechnical research for more than 30 years." Looking at Jiang Mingjing’s resume alone, there are nearly one page: Professor, Doctoral Supervisor, Department of Civil Engineering, School of Architecture and Engineering, Tianjin University; bachelor’s degree and master’s degree in engineering from Hohai University in 1986 and 1993, and doctor’s degree in engineering from nanjing hydraulic research institute in 1996. In 1998, he was a special researcher at Osaka Institute of Soil Testing (now Japan Institute of Regional Site Environment); in 1998-2000, he was a special researcher at Kyoto University in Japan; in 2000-2003, he was a postdoctoral fellow at Lavalle University; in 2003-2004, he was a postdoctoral fellow at the University of Nottingham in the United Kingdom; in 2004-2006, he was a professor at Tongji University School of Civil Engineering. Since 2018, he has been a professor and vice president of the School of Civil Engineering of Tianjin University. Since 2010, he has served as the vice chairman of TC105 Committee of the International Association of Soil Mechanics and Geotechnical Engineering (reelected), won the National Natural Science Outstanding Youth Fund in 2009, and was selected into the National Million Talents Project in 2014. The 22nd Huang Wenxi Lecturer, a highly cited scholar in China published by Elsevier (2019 and 2020), and a top 2% scientist in the world published by Stanford University (2020). Experts from the Advisory Committee of the Ministry of Industry and Materials of the National Natural Science Foundation, experts from the Water Conservancy Association, experts from the National Natural Science Award, and young and middle-aged experts who have made outstanding contributions to the country.Enjoy the special post of the State Council government …

There is no need to say anything about the difficulty and gold content of a doctor more than 30 years ago. "At that time, the scientific research conditions were really bad, but the overall academic atmosphere was very positive. Everyone was engaged in research and everything was for scientific research." Jiang Mingjing said that he was lucky to meet a group of good teachers, which not only pointed out the direction for him, but also paved the way for his future scientific research. "When I was studying for a master’s degree, my teacher applied for an exam-free PhD and advanced placement for me, which was unprecedented. At that time, it was the only one in our school." During Jiang Mingjing’s Ph.D. study, the personal research funds totaled only 6,000 yuan in three years. "Although the price was low at that time, it was still far from enough. The teacher took out his funds from the National Natural Science Foundation and made a special application for me. A total of 45,000 yuan was spent on my research projects."

Shoulder the heavy responsibility and live up to expectations. It used to be a worldwide problem to simulate large voids in structural soil. Through analysis, Jiang Mingjing thinks that adding ice particles into soil materials at low temperature can artificially form large voids, and finally the structural soil can be artificially prepared. For this reason, he made a detailed experimental design, which was quickly recognized by the teacher. Although the idea is good, where can we find such a low temperature environment? Until Jiang Mingjing saw the cold storage in the school canteen. "I told the teacher that I have found a way to do the experiment, but I have to trouble you to say hello to the school logistics department."

I heard that Dr. Jiang was going to do the experiment, and the logistics readily "gave the green light". Nanjing in midsummer is as hot as fire, just like Jiang Mingjing’s mood of looking forward to the experiment. "In order to do a good job in the experiment, we made all kinds of preparations as comprehensively as possible, such as equipment, cotton trousers, cotton-padded jacket … that day, we were all very excited, but we were dumbfounded as soon as we entered." The young student was ready for the experiment, but forgot to be mentally prepared-the cold storage belongs to the canteen, and all kinds of "animals" are completely frozen inside. "It’s funny to think of it now, but at that time, several classmates and I were scared to have nightmares at night."

The cold storage experiment was successful, and Jiang Mingjing pursued the victory. "As long as I am engaged in scientific research, I will always be full of combat effectiveness." In order to get the data as soon as possible, he kept his hands on the experimental equipment. The air compressor was used in the experiment, which was very loud, especially in the dead of night. "I am used to it myself, that is, I suffered the residents nearby. At first, some people reported to the director. Later, when everyone knew that they were doing the experiment, they all expressed their support and understanding. I am very moved by it in retrospect."

Thick accumulation can make thin hair. Jiang Mingjing’s research achievements have attracted wide attention in the world. He has not yet graduated from a doctor, and many world-renowned universities have sent him warm invitations. At the beginning of 1998, he went abroad and worked as a postdoctoral researcher in Osaka Soil Experimental Institute, Kyoto University, Lavalle University, Manchester University and Nottingham University. In 2006, with the belief of serving the motherland, he resolutely returned to Tongji University to teach.

During the interview, the reporter always had a feeling that scientific research was not a career for Jiang Mingjing, but a belief, a belief engraved in his bones and willing to follow him all his life. Like, love, obsession … These are not enough to describe his persistence in scientific research. "When I first returned to China, the salary I got a month was only 1,500 yuan, and the rent was 1,850 yuan. For a long time, I was supplemented by my previous savings."

The firm belief has brought Jiang Mingjing to this day step by step, and time has proved it best. In recent years, with the continuous strengthening of China’s comprehensive strength, the scientific and technological strength is also making rapid progress. Aerospace, deep-sea exploration … These sophisticated fields have left more and more China and China footprints. During this period, Jiang Mingjing and his team also undertook project research in many related fields. "In addition to the Martian soil just mentioned, the deep-sea soil is also the focus of our research in recent years. Recently, we are preparing to carry out exploration, development and environmental protection of combustible ice and other resources in Hainan. "

Adhere to the problem-oriented and face the major needs of the country. As an expert and scholar in the field, Jiang Mingjing is well aware of our current shortcomings and weaknesses. "Some key technologies, important equipment, new energy technologies and other fields that are related to the urgent needs and long-term needs of the country must be in our own hands, so we must speed up the pace and work hard in this direction."

From Jiang Mingjing’s words, the reporter can strongly feel his urgent and expectant mood. From a grain of sand to a piece of soil, from a mountain to a star, Jiang Mingjing has always closely linked scientific research with actual needs. Knowing the heavy responsibilities, but having the courage not to be afraid of failure; I also know that the road is far, and I still have the enthusiasm to concentrate on research.

At the end of the interview, the reporter asked Professor Jiang if he expected to visit space in the future. The professor smiled and said, "Of course! Space travel has been realized, which is not far from us. " Only after the hardships of being down-to-earth can we have the courage to look up at the stars. Similarly, we also expect Professor Jiang Mingjing to lead us to see a higher and further world with his scientific research achievements.

Exclusive dialogue

Reporter: Can you briefly introduce your research field?

Jiang Mingjing: My research field is soil mechanics, which is an applied discipline to study the stress-strain or stress-strain-time relationship and strength of soil under the action of force. It is a branch of engineering mechanics. The research object of soil mechanics is soil and soil closely related to human activities, including artificial soil and natural soil, and groundwater closely related to the mechanical properties of soil. Soil mechanics is widely used in the design of foundations, retaining walls, geotechnical structures and dams, and is an important branch of engineering disciplines such as civil engineering, geotechnical engineering, engineering geology and energy engineering.

The development of soil mechanics should be initiated by Coulomb, which can be roughly divided into three historical stages: germination period (1773-1923), classical period (1923-1963) and modern soil mechanics (1963-present). Modern soil mechanics is a system based on macroscopic test results, continuum mechanics method and macroscopic constitutive theory of soil, and numerical analysis methods such as finite element and finite difference are used as tools, which plays an important role in geotechnical engineering practice.

At present, with the continuous expansion of geotechnical engineering in space, especially the promotion of deep, deep-sea and deep-space engineering ("three-deep engineering"), researchers and engineers need to face more complex environmental conditions (high geostress, high/low temperature, high water pressure, high vacuum, low gravity, strengthening chemical action, etc.) and difficult geotechnical materials, such as structural soil (temperature, pressure and force coupling, T-

Reporter: After successfully completing the Mars exploration project, what is your current research focus?

Jiang Mingjing: Recently, I am mainly engaged in deep-sea engineering projects. With the rapid development of China’s coastal economy, the proposal of the "Belt and Road Initiative" and the promulgation of the "Thirteenth Five-Year Plan" for the development of the national marine economy, offshore engineering projects such as offshore wind power, cross-sea bridges, submarine tunnels, offshore oil drilling platforms, seawater power generation, submarine pipeline laying, land reclamation and marine nuclear energy are constantly increasing, and offshore engineering projects are constantly growing and enriching. Ocean engineering has changed from traditional engineering projects to new engineering projects, and gradually developed from offshore and shallow sea to far sea and deep sea. The scale of the projects is also expanding, which puts forward higher requirements for the sensitivity, safety and durability of ocean engineering. A series of marine resources development is accompanied by many engineering and technical problems that need to be solved urgently, such as the safety of mining platforms and submarine optical cables, and the early warning and mitigation of natural disasters such as submarine earthquakes and seabed landslides are also the core issues of global concern.

Taking the exploitation of deep-sea natural gas hydrate resources as an example, the decomposition of hydrate will inevitably lead to the deterioration of the mechanical properties of the seabed, and improper exploitation methods may induce large-scale disasters (such as landslides) or the collapse of pile foundation platforms. How to choose a safe mining mode and area to reduce the impact of mining activities on the marine environment has become the primary problem in the actual hydrate mining process. It is very difficult to conduct on-the-spot investigation and research on the seabed, and it is expensive to simulate the deep-sea environment by laboratory tests. Therefore, we need to strengthen scientific research and comprehensively analyze the promotion of marine engineering to ensure its safety and feasibility.

Reporter: After listening to your introduction, we probably know the practical application of soil mechanics. What are your professional opinions on the future development opportunities in this field?

Jiang Mingjing: A new key field of soil mechanics has emerged-macro-micro soil mechanics. In the past 40 years, macro-micro soil mechanics has experienced germination, embryonic form and growth period, so it can be said that it is now welcoming the stage of accelerated development. I think the development opportunities of macro and micro soil mechanics in the future mainly include the following four aspects.

The first is to establish an efficient calculation method suitable for various geotechnical engineering problems. The research in this field may involve the physical and mechanical mechanism on the molecular or nanometer scale, and it also needs efficient coupling calculation methods. Because hundreds of millions or even trillions of particles need to be calculated, this will require high computing power. With the rapid development of computer technology, this contradiction will gradually weaken.

Secondly, according to the real working environment, the model of the difficult rock and soil mass of the "Three Deep Projects" and the relationship between the structural evolution and the macro-characteristics are established. The research in this field not only needs the micro-and micro-scale experimental technology to simulate extreme environments such as high/low temperature, high water pressure, high vacuum and chemistry, but also needs to solve the contradiction between the scale effect of representative units and the limitation of experimental testing accuracy, and also needs to develop the extraction, processing and analysis technology of micro-and micro-structural information in three-dimensional soil. However, with the development of multifunctional, high-precision and large-range X-ray CT, these problems are expected to be solved step by step.

The third is to establish a practical theoretical model, and solve all kinds of complex and difficult core problems in geotechnical mechanics and engineering of "three deep projects" to help improve the engineering design level. In different geotechnical engineering problems, the stress path experienced by soil is different, so it is difficult to accurately obtain the stress path and mechanical properties of undisturbed soil in the field by current geotechnical testing technology. Therefore, it is a research idea to establish a practical constitutive model by using appropriate methods for simulation and corresponding indoor experimental research.

Fourth, the four branches of macro-micro soil mechanics and modern soil mechanics and the cross-development of other disciplines. Macro-micro soil mechanics can not only cross theoretical soil mechanics, computational soil mechanics, experimental soil mechanics and applied soil mechanics in this discipline, but also cross other disciplines, such as rock mechanics and near-field dynamics in mechanics disciplines. This will not only contribute to the self-development of macro-micro soil mechanics, improve modern soil mechanics, but also promote the rapid development of other disciplines.

In a word, macro-micro soil mechanics has become one of the most dynamic research directions, and its accelerated development period is coming soon. To this end, we need the participation of many young scholars with solid foundation and prime of life, as well as the care and support of senior researchers who have been fighting in the front line of scientific research for a long time and have a deep understanding of difficult and key problems in geotechnical engineering.

(Editor Liu Xiaoyan Han Jingfeng)

Dust pollution occurred in many places in northern China, and the local PM10 concentration exceeded 3600.

Country Garden announces new progress in overseas debt restructuring! A project team has been established.

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.

TGA’s best game inventory of the year: reviewing the excellent games of that year since eight years ago

The Game Awards, a new activity sponsored by Sony, Microsoft, Nintendo and Villefort, replaced VGA and VGX. The Game Awards is also known as the Oscar in the game industry. It has been eight times since it was founded in 2014, and the outstanding works that have been born in these eight years have all been nominated or won prizes at TGA. Then let’s review the winners of the current eight annual game awards and the competitors nominated that year.

2014 (First Session): Longteng Century: Trial

Nomination:

Bayonetta 2

Dark Soul 2

Hearthstone

Middle-earth: Shadow Mordor

Longteng Century: Trial is the third work in the series, and its development studio Bioware continues its consistent style. Created an interesting RPG world. Of course, there are some obvious shortcomings, its content is a little lengthy, and there are a lot of fragmented exploration content. However, in general, the defects are not hidden, and the high scores given by the media also make its first TGA annual game truly deserved. The other nomination games also set off a wave in that year. However, the volume is still slightly insufficient, so it is not too controversial that Longteng Century: Trial won the first TGA annual game.

2015 (Second Session): Wizard 3: wild hunt

Nomination:

Blood source

Radiation 4

Made in Super Mario

Metal gear 5: Phantom Pain

"Wizard 3: wild hunt" is indeed the pinnacle of CDPR, with rich game content; Fascinating plot, and the cooperation between witchcraft and fencing; And the Kunte brand game as a small egg. There is no doubt that you can feel the intention of CDPR at that time, and finally it won the best game of TGA in 2015. However, this year’s nominated lineup is Starlight Glimmer, Fromsoft’ware’s PS exclusive masterpiece Blood Source: Curse, the fourth generation of Radiation series, Nintendo’s popular series "Made in Super Mario" and Kojima Show’s last work in Kelemei "metal gear 5: Phantom Pain"; In this lineup, deus ex’s "Wizard 3" is even more valuable.

2016 (Third Session): Watching the Pioneer

Nomination:

Doomsday 4

《Inside》

The Fall of Titan 2

Mysterious sea 4: the end of thieves

If you want to ask what is the hottest game in 2016, then I’m afraid nine out of ten people will tell you that you are a watch pioneer. When Blizzard officially launched the game, it became popular all over the network. On the basis of adding skills to the FPS game in Legion Fortress 2, Blizzard further refined and designed various heroes. And then it was a great success. At that time, the most powerful competition of the annual game of Watching Pioneer was "Mysterious Sea 4: The Thief’s End" from the naughty dog studio. I privately thought that the game was the pinnacle of naughty dogs. At that time, both the exquisite picture and the design of checkpoint battles tended to be a perfect posture. Of course, in the end, Watch Pioneer still won the championship successfully. Compared with Mysterious Sea 4, Watch Pioneer’s phenomenal performance won it the annual game of that year.

2017 (4th): the legend of zelda: The Breath of the Wilderness.

Super Mario: Odyssey

Playerunknown’s Battlegrounds

Unusual Records of Goddess 5

Horizon: at dawn

That year’s TGA was a fairy fight, but the legend of zelda: The Breath of the Wilderness still stood out successfully. The breath of the wilderness handed in a perfect answer sheet in the production of open world games, and with the game mechanism, countless ways of playing can be played; Different designs of temples. The biggest winner in that year was Nintendo, which once again proved to the world that as long as the game is fun, it has nothing to do with the excellent picture quality. Even in the poor function of NS, you can appreciate the charm of this annual game.

2018 (Fifth Session): god of war 4

Nomination:

Marvel Comics Spider-Man

Fistful of dollars 2

Assassin’s Creed: Odyssey

Monster Hunter: The World

Blue

Santa Monica shows people what it means to be poor, and god of war 4 has changed a series of consistent combat modes. In the use of a new combat mode, Santa Monica still makes it very solid; Under the background of brand-new stories and myths, god of war 4 has succeeded in reinventing a world. What is more regrettable that year is fistful of dollars 2 from R star, which has a flavor from the western United States in picture performance, story narration and fighting mechanism. Even after many years, many players are still playing this game.

2019 (Sixth Session): "Only Wolf: The Shadow Dies Twice"

Nomination:

Control

Death stranded

Nintendo Star Wars

Resident Evil 2: Remastered Edition

Outer world

Hidetaka Miyazaki, who was full of malice, finally won his victory that year, and all the games owned by FromSoft were full of soul. And only the wolf uses the righteous hand and all kinds of moves to fight against Boss, and then it is natural to win the annual game award on the basis of the excellent fighting of the soul series.

2020 (Seventh): The Last Survivor 2

Nomination:

"gather! Animal Forest Friends Association

Doom Warrior: Eternity

Final fantasy 7: remastered version

Soul of Tsushima Island

Hades

Last year’s best game of the year was awarded to The Last Survivor 2, which was also controversial at that time. On the one hand, The Last Survivor 2 was the top one at that time in terms of play and picture quality, on the other hand, As an RPG, The Last Survivor 2 caused some players’ dissatisfaction in plot. Therefore, many players think that the annual game should be awarded to "Soul of Tsushima Island", and the Soul of Tsushima Island is a masterpiece with a solid gameplay and a distinctive artistic style.

2021 (Eighth Session): "Walking for Two"

Nomination:

Death cycle

Mitterrand: Fear of Survival

Brain pilot 2

Ricky and Tinker Bell: Time Jump

Resident Evil 8: Village

This year is recognized as a small game year, and there are few loud masterpieces released this year. As far as the quality of "Two in a Row" itself is concerned, it has successfully won the first prize. The very interesting play mechanism and excellent level design make this small game look very delicate.

Netease Cloud Music presented a song at the 20th anniversary of Netease, calling for Dad all the time.

[Text/Observer Network Zhuang Yi] This is a record company that has been delayed by enterprises and pigs, and there is no one.

On the occasion of the 20th anniversary of Netease, Netease Cloud Music specially launched "Ode to Netease’s Dad", reviewing Netease’s glorious history and sending blessings to one of the earliest Internet companies in China.

Whether it is lyrics, arrangement, singing or song cover, it can be called high-end atmosphere, low-key luxury and connotation. The catchy melody makes people unconsciously be substituted into it and hum softly, "Netease Dad ~"

It’s better to turn on the song and read the text

In a short time of 4:02, I sang the slogan that Netease Guangzhou is not easy to get rich, Netease News has an attitude, and the social intention of music.

Among them, the word "dad" appeared in the song for 10 times, which profoundly and vividly showed the gratitude and filial piety of the "good son" to his father, which was moving.

In addition, the beginning and the end echo, "I love work, and work makes me happy."Sing the voice of all office workers,"Overtime brings happiness"It is a wonderful experience that everyone can’t refuse.

It’s really gratifying to have such a "good son" ~

I love work, and work makes me happy.

Do you still remember the summer of memory?

The southeast coast of the motherland has a very developed economy.

My Netease father was in high spirits.

He started in Guangzhou with a unique eye.

Oh, bless dad. Bless dad

You are easy to surf the internet for the people.

This ideal, this great ideal

Take firm steps all the way

Ah, thank you, dad. Thank you, dad

(Please turn the page for excerpts of complete lyrics) …

That’s it? No, this song also has a companion piece-"Netease YEATION Refunds Money".

Please consciously bring in the tune of "cordate telosma" and hum it. Is it catchy?

There was an article a few days ago.

Dirt YEATION’s towel.

The boss said hum was super unpleasant.

Tell you what, the price will drop.

Is twelve yuan a strong one?

What should I do if I buy it before the price is reduced (what should I do ~ what should I do ~)

What about expensive users (what to do ~ what to do ~)

The boss said again, little fool

It’s easy. We’ll refund the money.

Every order is refunded.

Refund the money

Netease, a famous pig factory in Hangzhou, Zhejiang, has been recruited on the Internet.

Yun Music Cloud Classroom YEATION Koala Beishangguanghang Beishangguanghang

If you want to recruit, you have to recruit 1,800 people. When you see the demand, HR will be stupid.

We have no, no way, no way to do school recruitment by internal promotion.

All colleges and universities that originally wanted 985211 were exempt from screening.

No screening, no screening, no screening, no screening, no screening.

……

It’s enough for a record company delayed by an enterprise to sing without saying anything …
