"Qin Shu" fragrant Sanqin

Shaanxi Daily (11th edition, May 5, 2022)

On April 11th, Zhu Weibing (right), the person in charge of the base, and Liu Mengjun, an associate professor at the Agricultural College of Northwest A&F University, exchanged sweet potato seedling techniques at the seedling base of Yangling Golden Potato Seed Technology Co., Ltd..

April 15thWorkers are harvesting sweet potato seedlings in Tianxi Village, Rougu Town, Yangling District, Yangling Demonstration Zone.

■ The total planting area of sweet potato in Shaanxi is about 800,000 mu, and the yield per mu is about 2,000 kg.

■ After more than half a century, sweet potato breeding experts in our province have bred a series of new sweet potato varieties, among which the promotion area of "Qinshu No.5" accounts for about 80% of the total sweet potato planting area in our province.

■ Heichi Town, Heyang County, Weinan City, Ganguyi Town, Baota District, Yan ‘an City, Cuijiawan Town, Suide County, Yulin City, and Guo Wang Zhen, Fengxiang District, Baoji City, the four major sweet potato industry towns in our province are famous in the northwest.

Most people have a sweet potato complex-planting several ridges of sweet potato seedlings in farmland and digging sweet potatoes in autumn is really interesting; Take out a few sweet potatoes from the cellar and put them into the fire. The most primitive cooking method makes them delicious …

In fact, sweet potato is an exotic product. Since it was introduced to China for more than 400 years, it once became an important crop to replace people’s staple food, which provided food security for China’s population growth and played a great role in avoiding famine and disaster. The sweet potato buried deep in the soil still cherishes people’s deep memories, forming a unique sweet potato culture in China, which nourishes our lives to this day.

In recent years, the concept of diet balance has been deeply rooted in people’s hearts, and the "sweet potato fever" has risen again. Sweet potato, once used to fill the stomach, has become synonymous with health and nutrition. Driven by the large-scale, technical and green planting standards of sweet potato, the four major towns of sweet potato in our province are famous in the northwest, and the deep processing industry of sweet potato has a strong development momentum. Sweet potato not only brings sweetness to people, but also opens a way to get rich.

"Sweet potato fever" has risen again.

Yangchun March is not only the most beautiful season in the world, but also the season of cultivation and sowing. In this season of "planting melons and beans", Yangling, an agricultural city, entered the busiest time. From the beginning of April, customers who came to buy sweet potato seedlings in the sweet potato seedling base of Yangling Golden Potato Seed Technology Co., Ltd. were in an endless stream.

In recent years, the total planting area of sweet potatoes in our province is about 800,000 mu, mainly for edible commercial potatoes, and the yield per mu is about 2000 kg. Every year, about half of the sweet potatoes produced in Shaanxi are supplied to the local market, and the rest are sold to Gansu, Xinjiang, Ningxia and other places. Moreover, in order to ensure the variety of sweet potatoes in the market, Shaanxi also purchases local sweet potatoes from Shanxi, Henan and other places every year.

"Sweet potato contains a variety of nutrients, especially it is rich in lysine. Eating sweet potato with rice and flour can make the nutritional composition more comprehensive. Sweet potato is low in fat and heat energy, and contains nutrients that can regulate the acid-base balance of human body, inhibit cholesterol production, lower blood sugar level, and prevent sub-health and cardiovascular and cerebrovascular diseases. It can be called health food, longevity food and anticancer food. " Ren Yamei, an associate professor at the College of Food Science and Engineering, Northwest A&F University, introduced.

Shaanxi sweet potato has good quality and taste, which is very suitable for steaming and roasting, and it is often in short supply in the market. Driven by interests, every link of the sweet potato industry chain, such as seedling raising, planting, storage and processing, has become a "magic weapon" for people to increase their income and get rich.

On April 15th, farmers from Fufeng, Wugong and Ganxian came to the sweet potato seedling base in Tianxi Village, Rougu Town, Yangling District, Yangling Demonstration Zone to buy seedlings. In the fields, rows of greenhouses are warm and harmonious, and sweet potato seedlings are growing vigorously. "There are 18 sweet potato seedling greenhouses in Tianxi Village, and more than 10 million virus-free sweet potato seedlings are cultivated every year, which are mainly supplied to the surrounding sweet potato farmers." Liu Xinmin, head of Tianxi Village sweet potato seedling base, said.

"Driven by the sweet potato seedling industry and under the guidance of experts and professors from Northwest A&F University, there are 15 villagers in Tianxi Village developing 26 sweet potato seedling greenhouses, and the average annual income of sweet potato seedling farmers exceeds 100,000 yuan." Tian Xiaoxiong, secretary of the Party branch of Tianxi Village, said.

With the popularity of sweet potato, sweet potato storage has become a business. It is understood that about half of the sweet potatoes harvested in autumn in our province are directly listed, and some sweet potatoes are stored in earthen pits to ensure that they can be sold all year round, and can be supplied from October to March next year. Pit-stored sweet potatoes are listed during the Spring Festival, avoiding the low price period caused by the large supply of fresh potatoes in season, and most of them can sell at good prices.

In recent years, Shuguang Sweet Potato Professional Cooperative in Heichi Town, Heyang County has carried out in-depth development of sweet potatoes on the basis of developing fresh sweet potatoes, producing a series of products such as sweet potato flour, sweet potato vermicelli, sweet potato starch and sweet potato old sugar, and promoting the diversified development of sweet potato products.

Sweet potato love between two generations

In 1950s, Sheng Jialian, a Chinese sweet potato breeding expert, brought back sweet potato breeding resources from the United States and Japan, and gave some of them to Professor Niu Lianxing of Northwest Agricultural College (now Northwest A&F University). As a student of Professor Niu Lianxing, Zhu Junguang began to work on sweet potato breeding, and after more than half a century, he developed a series of new sweet potato varieties.

In the 1990s, a new sweet potato variety "Qinshu No.4" bred by Zhu Junguang and others was demonstrated and popularized in our province. Its outstanding feature is that it can be used for both steaming and starch processing, and farmers affectionately call it "market potato". In 2006, Zhu Junguang and others bred a new sweet potato variety "Qinshu No.5" and gradually popularized it. At present, the promotion area of "Qinshu No.5" accounts for about 80% of the total sweet potato planting area in our province.

During the sweet potato breeding, Zhu Junguang learned from the traditional sweet potato planting methods, such as oblique planting, direct planting and flat planting, and summed up a "horizontal improved cutting method" that is suitable for the local area and ensures survival. First, the sweet potato seedlings are inserted into the soil to take root, then the sweet potato seedlings are laid down and buried shallowly, and finally the long vines at the top of the sweet potato seedlings are exposed, and the sweet potato seedlings are deeply inserted to protect the seedlings and buried shallowly. This method can not only ensure the survival rate, but also effectively increase the potato yield.

After many years of practice and exploration, Zhu Junguang summed up a set of practical techniques for planting sweet potatoes suitable for farmers-"high ridge to grow big potatoes and raise big fish in deep water" means that sweet potatoes are suitable for ridge planting, and high yield can only be achieved by "eating and drinking well"; "A litter of ashes, sweet potatoes in piles" means that potash fertilizer should be the main fertilizer for sweet potatoes …

"Breeding work is hard and tiring, and you can’t make money. At the beginning, I didn’t want to do this. " Zhu Weibing said. In 1997, under the guidance of his father Zhu Junguang, Zhu Weibing "drilled" into the sweet potato breeding greenhouse. At that time, Zhu Junguang was well-known in the sweet potato breeding industry in China.

In 1998, Zhu Weibing began to develop market-oriented breeding of sweet potato seedlings on the basis of his father’s breeding of new sweet potato varieties. At that time, Zhu Weibing had only two greenhouses for seedling raising, and about 400,000 sweet potato seedlings were sold every year. At that time, a farmer in Famen Town, Fufeng County purchased "Qinshu No.4" sweet potato seedlings from Zhu Weibing and planted them. In that year, he earned more than 6,000 yuan by selling steamed sweet potatoes.

High-quality sweet potato seedlings bring real money to farmers. At this time, Zhu Weibing felt that the market-oriented breeding of sweet potato seedlings had great prospects. Around 2000, Zhu Weibing established a seed company, specializing in sweet potato seedling raising.

How to breed high-quality sweet potato seedlings in batches? Zhu Weibing took a lot of thought. First, let the seed potatoes sleep "Simmons", combine the electric hotbed with the solar greenhouse, and adopt the technology of centralized germination and separate bed potato arrangement to make the sweet potato seedling grow quickly and economically. The second is to let the seed potatoes eat "western food", create soilless sweet potato seedlings, and use all-organic nutrient fertilization technology to solve the problems of easy pollution of nutrient solution for hydroponic seedlings and the prevalence of soil-borne diseases in traditional seedlings. Thirdly, the virus-free technology is combined with multi-stage, rapid and efficient seedling raising methods to effectively improve the propagation coefficient of sweet potato seedlings.

Today, Zhu Weibing has 28 sweet potato seedling greenhouses, and about 10 million sweet potato seedlings are bred every year, which are mainly supplied to large sweet potato growers in the province. "Sweet potatoes have the habit of asexual reproduction, so the income from seedling breeding is limited. We are considering more to promote the excellent varieties of sweet potatoes on a large scale, so that more farmers can benefit from it. " Zhu Weibing said frankly.

The regional characteristics of "Qin Shu"

Today’s sweet potato has become a spice in people’s lives. At present, sweet potatoes are distributed in Guanzhong, northern Shaanxi and southern Shaanxi. Some sweet potatoes in northern Shaanxi are soft and sweet varieties. The dried sweet potatoes in Guanzhong are delicious and suitable for steaming and roasting. The sweet potatoes in southern Shaanxi are mainly used to produce starch and feed. There are different varieties and processing channels of sweet potato in northern and southern Shaanxi, and farmers’ cognition of sweet potato is also different.

In recent years, our province has vigorously developed the sweet potato planting industry, and has formed four major sweet potato industry towns: Heichi Town, Heyang County, Weinan City; Ganguyi Town, Baota District, Yan ‘an City; Cuijiawan Town, Suide County, Yulin City; and Guowang Town, Fengxiang District, Baoji City. The sweet potato planting industry has gradually changed from decentralized operation to large-scale, technical and green.

On April 17th, in the planting base of Jinshuyuan Agricultural Cooperative in Guowang Village, Wang Zhen, Fengxiang District, Zhang Jianke, the person in charge, was leading the workers to plant sweet potato seedlings. In 2020, Zhang Jianke and his partners established the Golden Potato Garden Agricultural Cooperative, and accumulated 120 mu of land to grow sweet potatoes.

"Every year, the cooperative’s commodity sweet potato output is more than 200,000 kilograms. In the sweet potato harvest season, merchants parked their trucks on the ground to grab the goods. This year, the cooperative plans to introduce a sweet potato vermicelli processing factory to further process some sweet potatoes to increase profits. " Zhang Jianke said.

At present, Wang Zhen has planted 15,000 mu of sweet potato, and radiation has driven the surrounding towns and villages to develop 30,000 mu of sweet potato planting. "Guo Wang Zhen has formed an integrated industrial chain of sweet potato breeding, planting and deep processing. In the next step, we plan to introduce sweet potato starch processing plants, pet feed factories and other enterprises to further enlarge and strengthen the sweet potato industry and drive the people to increase their income and get rich. " Xing Wenrang, vice mayor of Guo Wang Zhen, said.

It has become a trend to plant sweet potatoes in contiguous areas in our province, and behind the large-scale planting is the effective application of new technologies and new machinery. In mid-April, in the sweet potato planting base in Ganguyi Town, Baota District, farmers were turning over the ground and ridging to prepare for planting sweet potatoes. "The sweet potato planting area in Ganguyi Town is about 10,000 mu. The sweet potato planting base is equipped with machinery such as rotary tillage, ridging, deep ploughing, film mulching and harvesting. Farmers can also modify the machinery according to actual needs, and the sweet potato industry is fully mechanized from planting to harvesting." Guo Qiping, mayor of Ganguyi Town, said.

In 2019, Ganguyi Town cooperated with Northwest A&F University in "Industry-University-Research" to build the first town-level sweet potato science and technology expert compound in the province, and hired technical experts to take the pulse for the development of sweet potato industry in Ganguyi Town. In order to solve the problem of quality degradation caused by long planting time of local sweet potatoes, experts from Ganguyi Town jointly detoxified local sweet potato seedlings, which fundamentally solved the problem of productivity decline and quality degradation of sweet potatoes.

With the change of people’s consumption concept, healthy nutrition has become one of the important standards of food production and processing. During the development of sweet potato industry, Heichi Town vigorously promoted the use of organic biological fertilizer, bacterial fertilizer and physical pest control measures to ensure the green and healthy sweet potato products. Heichi Town also signed an eco-agricultural technical service agreement with scientific research institutes to carry out green ecological sweet potato production technology experiment and demonstration.

The old-fashioned famous enterprise Digital Source Technology has fallen and made a living by building affordable housing.

K figure 000909_2

  Zero growth in market value after 14 years of listing, the secretary-general has no idea about the basic business.

  Among the 244 A-share listed companies in Zhejiang, nothing is more tangled than Digital Source Technology Co., Ltd. (00090, hereinafter referred to as "Digital Source Technology").

  This company in the name of "science and technology" has been a high-tech enterprise in Zhejiang Province since its listing, enjoying 15% income tax concessions. The company is not without high-tech products. The digital source brand set-top box it produces is the largest purchasing brand of China Digital Media (000156), a listed company in the same city. In 2012, China Digital Media purchased 69.73 million yuan of digital source technology, accounting for 9.23%.

  However, in the stock trading software, Digital Source Technology has been classified as "real estate industry". Because the real estate business (including the construction of a large number of affordable housing) has already constituted the main profit source of this "high-tech enterprise".

  In 2012, the profit of Digital Source Technology’s real estate business reached 57.70%, while its real main business, audio and video products, accounted for only 21.92%.

  When it was listed in 1999, the leading product of Digital Source Technology, "Xihu Brand" color TV, was famous in China, especially in Zhejiang. However, times have changed, and Digital Source Technology has long since faded out of public view and become a declining brand that almost no one has mentioned.

  After 14 years of listing, Digital Source Technology has almost stagnated, and there is no refinancing behavior such as an additional issuance. The share capital has remained in the state of listing for 14 consecutive years; The company has not paid dividends for 11 consecutive years, and only paid dividends twice in 2001 and 2012, with a dividend amount of only 39 million yuan.

  What is even more ironic is that this high-tech listed company, which works in the best location in Hangzhou, uses computers with huge CRT monitors, and the company is in a gloomy atmosphere. The secretary-general of the company, who has served for more than ten years, even has no idea about many businesses of the company.

  The next year after listing, it lost money for 11 years without dividends.

  The controlling shareholder of Digital Source Technology is Xihu Electronics Group Co., Ltd. (hereinafter referred to as "Xihu Electronics"), which currently holds 53.23% of the shares. Xihu Electronics was established in September 1995 (formerly known as Hangzhou Dongfeng TV Factory was founded in 1973). It is a comprehensive enterprise group controlled by Hangzhou Municipal Government, which integrates many industries such as industry, microelectronics, commerce, economy and trade, transportation and real estate development. It is a leading enterprise in the electronics industry in Zhejiang and Hangzhou, and one of the 520 large state-owned enterprises in China. Today, Digital Source Technology and West Lake Electronics are both working in No.1 Jiaogong Road, Hangzhou, which is the top location in Hangzhou and is located in the core of Hangzhou Huanglong Business Circle. West Lake Electronics covers an area of 290,000 square meters, and its land assets alone are several billion yuan.

  In July, 1998, Xihu Electronics, as the exclusive sponsor, discounted its assessed operating net assets of three wholly-owned subsidiaries, namely Hangzhou Xihu Electronic Industry Co., Ltd., Hangzhou Xisha Electric Appliance Corporation and Xihu Electronic Group Injection Mould Co., Ltd., and established Digital Source Technology by way of fundraising.

  In May 1999, Digital Source Technology went public with 60 million shares at an issue price of 5.18 yuan. Its P/E ratio is 17 times, the lowest in Shanghai and Shenzhen stock markets in 1999.

  According to the Prospectus of Digital Source Technology, the digital processing color TV set developed by the company is in a leading position in China, reaching the advanced level of international similar products in the mid-1990s. The company’s main digital technology electronic products belong to the latest technical trend in the world, with "very broad prospects".

  At that time, the main products of Digital Source Technology were Xihu brand color TV sets, with sales accounting for more than 90% in 1996-1998. Xihu brand color TV was once one of the famous color TV brands in China. It won the first prize in all previous evaluations in 1980s and 1990s, and won the titles of National Silver Award, National Customer Satisfaction Product and Top Ten Best-selling Color TV in China Market in 1995. After the listing of Digital Source Technology, it was once popular in the market. In February 2000, its share price reached as high as 26.9 yuan, more than five times its issue price.

  The scenery of digital source technology is only a flash in the pan.

  Ironically, Digital Source Technology, a high-tech brand, has just been listed, and the situation of domestic color TV industry has turned sharply, becoming a traditional industry and even a sunset industry. After years of "price reduction war" for domestic color TV sets, by 2000, the color TV industry with excess capacity suffered losses in the whole industry. According to statistics, the profit rate of the whole industry in 2000 was only 2%, and the total profit was only 540 million yuan.

  In this context, in the first half of 2000, Digital Source Technology suffered a huge loss of 16.72 million yuan, while the after-tax profit before listing in 1998 reached 50.45 million yuan. The retail price of some color TV sets of the company is lower than the cost price, and even several models are lower than the material price.

  After listing in 1999, the total share capital of Digital Source Technology was 196 million shares. This capital structure has been maintained for 14 years, and the market value of the company has not increased at the time of listing. The company has not paid dividends for 11 consecutive years, and only paid dividends twice in 2001 and 2012, with a dividend amount of only 39 million yuan.

  In April this year, Digital Source Technology released the plan of converting 10 shares of common reserve fund into share capital. By June 18th, the total share capital of the company will be changed for the first time, reaching 294 million shares.

  In the past, famous scientific and technological enterprises became developers of affordable housing

  According to media reports, in November 2000, West Lake Electronics, which suffered serious losses, ranked second among the 520 key supporting enterprises in China, and faced the fate of being merged or bankrupt.

  Digital source technology is also struggling on the edge of loss. From 2000 to 2007, the company’s net profit has been less than 5 million yuan, and in 2008 it suffered a huge loss of 18.59 million yuan.

  Since 2009, the performance of Digital Source Technology began to pick up, with a net profit of 20,261,400 yuan. Since then, the annual net profit has remained above this base.

  However, this is basically thanks to Hangzhou Zhongxing Real Estate Development Co., Ltd., a wholly-owned subsidiary of Digital Source Technology. In 2012, ZTE Real Estate contributed a profit of 54,963,300 yuan. The profit accounted for 57.70% and the gross profit was 30.13%.

  Hangzhou Zhongxing Real Estate Development Co., Ltd. was jointly invested and established by Digital Source Technology, Hangzhou Yihe Network Co., Ltd. and Xihu Electronics Group Co., Ltd., and was incorporated in November 2000. At this time, Digital Source Technology has just been listed for more than one year.

  The original registered capital of the company is 13.15 million yuan, of which Hangzhou Yihe Network Co., Ltd. (formerly a joint venture between Xihu Electronics and Digital Source Technology, which is now wholly owned by Digital Source Technology) contributed 12.4925 million yuan, accounting for 95.00% of the registered capital; Xihu Electronics contributed 657,500 yuan, accounting for 5% of the registered capital.

  In 2001, ZTE Real Estate increased its capital, and Digital Source Technology exclusively invested 46.85 million yuan, holding 78.08% of the shares. In 2006 and 2008, Digital Source Technology increased the capital of ZTE Real Estate twice. The registered capital of the company reached 200 million yuan, and Digital Source Technology accounted for 93.42% of the shares. Since then, through equity transfer and indirect shareholding, ZTE has become a wholly-owned subsidiary of Digital Source Technology. With the gradual control of ZTE’s real estate by Digital Source Technology, the proportion of real estate business in Digital Source Technology is increasing.

  There are more than ten project companies under ZTE Real Estate, including eight "Jing" prefix companies located in Hangzhou, such as Jingran, Jingcan, Jinghe, Jingjing, Zhongxing Jinghe, Zhongxing Jingzhou and Zhongxing Jingtian. These companies are almost all affordable housing construction projects in Hangzhou. In 2012 alone, there were eight affordable housing projects under construction in Hangzhou.

  For example, ZTE Jingtian was established in October 2005, and the development project is the affordable housing "Ding Qiao Jingyuan" located in Ding Qiao, Hangzhou; Zhongxing Jingzhou was established in June 2006, and its development projects are affordable housing "Jingzhou Apartment" and "Jingcui Apartment" located in Yang Jiacun, Xiacheng District, Hangzhou. These projects have been put into use.

  At present, the affordable housing projects under construction by other subsidiaries of Zhongxing Real Estate include the demolition and resettlement houses in Hangzhou Huayuangang Village, affordable housing in Hangzhou Jingran Jiayuan, affordable housing and low-rent housing projects in Hangzhou Changmu large residential area, affordable housing in Sandun North plot in Hangzhou, and special housing for talents in the north of Hangzhou Economic Development Zone (agent construction project).

  However, the gross profit margin of affordable housing construction is very low, basically only about 3-5%. In 2012, the gross profit margin of ZTE real estate was as high as 30.13%, which was obviously the contribution of commercial housing projects. Among them, two foreign projects, Hefei West Lake Garden and Zhuji Jingcheng Jiayuan, account for the most important.

  Employees who have not implemented equity incentives muddle along.

  In the eyes of many investors, although Digital Source Technology, which has been listed for 14 years, has many concepts such as affordable housing, 3D, equity investment and digital TV, its operating profit has not improved greatly, and it has almost been forgotten by institutions. Eight of the top ten shareholders of the company are natural persons, and their shareholding ratio is less than 0.3%. In the whole year of 2012, Shanghai Zexi Investment Management Co., Ltd., a subsidiary of Xu Xiang, a well-known private equity firm, was the only company to conduct on-site investigation.

  "West Lake Electronics has been shackled by state-owned enterprises, but this shackle is not tangible-even the government departments have been laissez-faire in the development of West Lake Electronics, and the’ state-owned enterprise disease thinking’ of the planned economy is the real shackle." Zhang Guojing, who became the general manager of West Lake Electronics in 2001 (as the chairman after August 2003) and the chairman and general manager of Digital Source Technology, once told the media. Zhang Guojing was only 38 years old at that time, and was highly expected by the higher authorities, hoping to lead Digital Source Technology and West Lake Electronics back to life.

  In the view of Zhang Guojing at that time, West Lake Electronics, including Digital Source Technology, suffered from a serious "state-owned enterprise disease". "West Lake Electronics used to be a bureau-level unit in Hangzhou, and its institutional style was still quite popular."

  Although under the leadership of Zhang Guojing, Digital Source Technology and West Lake Electronics have made a lot of market-oriented efforts, Ceekay, a state-owned enterprise, is far from being able to change overnight. Today, Zhang Guojing, who earns an annual salary of 857,600 yuan, is 50 years old and no longer young. Digital Source Technology has returned to its former state, and even the large computer display screen that has long been eliminated by the market is too lazy to update.

  Some people familiar with the matter believe that this may be related to the fact that the company has not implemented equity incentives.

  In December, 2005, Digital Source Technology passed the share reform, becoming the first state-controlled listed company with successful share reform in Zhejiang.

  At that time, Zhang Guojing believed that the share reform into digital source technology had gained unprecedented strategic development opportunities, and it would be easier to carry out mergers and acquisitions through the capital market, and it would be more feasible to integrate industries, eliminate the fittest and introduce international strategic investors.

  "Digital Source Technology will set up an equity incentive plan under the institutional arrangements of the SASAC and the China Securities Regulatory Commission to ensure the long-term development of listed companies." Zhang Guojing once said with confidence that besides the company’s management, the company’s technical backbone, sales backbone and production backbone will be the key incentive targets.

  However, in the past eight years, equity incentives have not been followed, and the foreign acquisitions and mergers that Digital Source Technology hopes for have become a dream. Because of the bleak performance, Digital Source Technology was once rumored by the market that it would be backed by China Digital Media, and it has been supported by real estate business until today.

  "Without an incentive mechanism, most people in the company are muddling along." An industry insider familiar with digital source technology told the Times Weekly reporter.

  A case in point is that when the reporter interviewed Yi Ding, the company’s director-general, he didn’t know all the basic questions about the company’s profit composition, what real estate projects were settled in 2012, and why the gross profit margin of real estate companies was high. He said that he would ask the finance department before giving a reply, but there was no news since then. Similar to Zhang Guojing, Yi Ding has been the Secretary of the Company for 12 years, with an annual salary of 626,600 yuan.

Attack the big model! ByteDance AI software and hardware ecology is taking shape.

Science and technology innovation board Journal, December 18th (Reporter Huang Xinyi)At the Force conference in Volcano Engine, Tan Dai, president of Volcano Engine, announced that as of mid-December, the daily average usage of tokens of the bean bag universal model had exceeded 4 trillion, which was 33 times higher than that when it was first released seven months ago.

The previous list of monthly active users in the world shows that the MAU of Bean Bag App is close to 60 million, ranking second in the world after ChatGPT of OpenAI.

At the meeting, ByteDance officially released the visual understanding model of bean bags, the 3D generation model of bean bags, and the comprehensive upgraded universal model of bean bags, such as pro, music model and Wensheng diagram model. Among them, the input price of the visual understanding model of bean bags is only 3%, and one yuan can handle 284 720P pictures. The conference also announced that ByteDance will launch version 1.5 of the video generation model of Bean Bag with longer video generation capability in the spring of 2025, and the end-to-end real-time voice model of Bean Bag will be launched soon.

The science and technology innovation board Journal reporter learned exclusively that,Volcano Engine Edge Cloud and Runxin Technology jointly create AI voice toys, and its Wi-Fi module adopts Hengxuan Technology. Graffiti Intelligence also participates in providing related modules and docking platforms..

From the live experience, consumers can interact with the AI toy "puppy" in voice, so that they can answer questions and provide companionship.

Some people in the industrial chain expressed optimism about the follow-up sales of AI voice toys. He told the science and technology innovation board Journal reporter,It is expected that the first batch of AI toys will be listed at the end of this year and early next year. It is expected that a large number of players will join the competition in the industry in the first half of next year.However, the landing of AI toys also has certain challenges. "First of all, AI toys need to be based on high-quality knowledge bases of different age groups in order to achieve better human-computer interaction. Besides,The daily interaction frequency of AI toys is high. For users, the cost of cloud reasoning will be a big expense, and it is also a difficulty that affects its landing.. "

At the meeting,Volcano Engine Video Cloud, Lexin Technology and ToyCity jointly launched the AI+ Hardware Smart Jump Program., combined with the big model of bean curd, Volcano Engine’s anthropomorphic voice dialogue technology, ToyCity tide play design, as well as the AI chip of Lexin Technology and other product strengths, to promote the popularization of AI tide play. It is reported that Lexin Technology will provide a one-stop hardware solution for AI Chaowan, including end-side audio and video processing.

In terms of robots,Horizon’s sweet potato robot and Volcano Engine Edge Cloud are developing intelligent robots based on large model gateways.A robot intelligent perception and control system scheme based on edge large model gateway is built.

Facing the robot call scenario, the big model gateway can make use of the edge to call the big model service nearby based on the originating position of the end-side request, and improve the response speed and ensure the call stability through the product capability of the edge big model gateway, so as to realize the near access and query acceleration of the big model for robot equipment and call it on demand at a lower price and faster speed.

In addition, Leju Robot also cooperates with the bean bag model. At present, Leju robot is mainly used in scientific research, exhibition hall tour, etc., and is also exploring the application in the industrial field.

In terms of end-side AI, the bean bag model has been connected to many smart terminals such as mobile phones and PCs, covering about 300 million terminal devices, and the call volume of the bean bag model from smart terminals has increased by 100 times in half a year.

It is reported that HONOR’s magic retouching and AI abstract functions are provided by the bean bag model, and vivo mobile phone adopts the bean bag music model, which provides music creation ability for photo album users. Bean bag music model will create AI lyrics and songs according to the materials provided by users, and generate personalized movies for users.

Tan Dai told science and technology innovation board Daily that most Android phones in China are cooperating with Doubao. “For mobile phone manufacturers, bean bags will be used in some scenes, other large models will be used in some scenes, or a certain scene will be mixed.. For enterprise users, a cloudy or multi-model strategy is definitely needed, which I think is normal. In the end, the ability is better and the cost is lower. Who will be used? This account is easy to calculate. "

The reporter of science and technology innovation board Daily found on the spot that a large number of application scenarios have been explored based on ByteDance’s AI agent development platform button.

For example, cooperate with Supor to explore the generation of AI personalized recipes and improve the service level of cooking machines.

AI fish farming in cooperation with Ji Zhiyun, the agent automatically provides users with an optimization scheme according to the real-time data of fish tank equipment. For example, when the water quality is not up to standard, the agent can automatically adjust the operation mode of the pump to improve the growth environment of fish or plants.

It is reported that there are more than 1 million active developers in the agent development community of Button, and more than 2 million agent applications have been created.

In terms of car companies, Dongfeng Motor, Zhiji Automobile, and Mercedes-Benz’s SMART Car have cooperated with the bean bag model in smart cockpits and other aspects. Tan Dai said that more than 80% of domestic mainstream automobile brands are cooperating with the big model of bean bag.

ByteDance is expected to launch version 1.5 of the video generation model of bean curd with longer video generation capability in the spring of 2025. Talking about the possible computational challenges, Tan Dai said, "The Volcano Ark provides MaaS reasoning service for the large model of bean curd, which I think is sufficient from our own reserves. It is for this reason that we can now provide the industry’s largest TPM and RPM. When the user is stuck or blocked, this is not necessarily the reason for insufficient computing power. After all, you are using an application and a system. Even if there is something wrong with the user’s authentication, it will affect the fluency of the whole system, including whether there is engineering optimization. This is actually not just a simple calculation problem. "

For the market competition in the future big model field, Tan Dai said that it is still in the early stage of the market. "To be honest, from my point of view, I don’t care much about competition now, because this market is still very early, and maybe one thousandth of this market has just been developed. At this time, you don’t really have to care about competition. What you care about is what users’ needs are not met. "

The man lost 170,000 yuan in smuggling gambling six times, and was arrested and brought to justice by the police for suspected crimes.

  Smuggling gambling in Myanmar not only lost all property, but also violated the criminal law. On March 29th, the Public Security Bureau of Jianghan Oilfield in Hubei Province informed that Tian, a man suspected of smuggling into the country (border), was arrested and brought to justice according to the clues of his superiors.

  Tian, 59, is from Jianghan Oilfield. In April 2019, Tian planned to travel to Myanmar when traveling in Yunnan, and then went to Daluo Port in Menghai County, Yunnan Province for consultation. The port staff told him that he could not enter the country without applying for a Myanmar visa.

  "Tian was accosted near the port, and the other party said that only 300 yuan could help him sneak into Myanmar. Tian readily agreed and sneaked into Myanmar by motorcycle." The police investigating the case told Jimu journalist that after arriving in Myanmar, a person soliciting customers for the casino recommended the casino to Tian, and said that "accommodation, accommodation and shuttle bus can be provided. If the money is lost, you can return part of it and help book the air ticket for free. " Out of curiosity, Tian entered the casino. As a result, I soon lost all my 20,000 yuan in cash and 36,000 yuan in credit cards. Tian, who was forced to do nothing, had to call back to China and borrow money from relatives and friends to return home.

  The police investigating the case said that after receiving the money, Tian reserved a part of the tolls, then entered the casino again to gamble, and soon lost again.

  "He booked a plane ticket to return to China at that time. Because the flight was half a month later, he found a job driving a truck in Myanmar for half a month and then returned to Yunnan by smuggling." The police investigating the case introduced that in June 2019, after Tian returned to China, he sold his house in Qianjiang and paid off his credit card debt. At this time, he received a phone call from the Myanmar casino and invited him to gamble.

  It turned out that after selling the house to pay off debts, Tian had 70,000 yuan left on hand. After receiving the invitation, Tian, who was "bent on turning over the book", booked a ticket to Yunnan. Under the arrangement of the casino, Tian once again sneaked into Myanmar and entered the casino to "catch up". It didn’t take long to lose all the 70,000 yuan he brought. After the money was lost, Tian sneaked back to China again and then flew back to Wuhan.

  According to the police investigating the case, in January 2020, Tian, who was "unwilling to change", once again raised 40,000 yuan for gambling and went to Yunnan to sneak into Myanmar in the same way. Not surprisingly, 40,000 yuan of gambling money also hit Shui Piao. In February 2020, due to the epidemic situation, the Myanmar police investigated foreigners staying in Myanmar, and then sent Tian to Daluo Port on the China-Myanmar border and handed him over to the local border police station.

The man lost 170,000 yuan in smuggling gambling six times, and was arrested and brought to justice by the police for suspected crimes.

  The suspect was arrested and brought to justice.

  "After returning to China two years ago, Tian has been staying in China." According to the police investigating the case, on March 23 this year, the exit and entry administration department of Jianghan Oilfield Public Security Bureau immediately launched an investigation with the May 7th police station in the jurisdiction after receiving the instructions from the superior, and summoned Tian to the police station according to law. After investigation, Tian was addicted to gambling on weekdays. After the termination of the labor contract with the unit, he was bent on "making a fortune" in Myanmar casinos. During 2019-2020, he went to Yunnan Province many times, without going through the entry and exit documents according to law. In the case, he entered Myanmar by smuggling and participated in gambling activities in local casinos.

  After being brought to justice, the suspect Tian confessed the fact that he illegally crossed the border between China and Myanmar six times in two years, and participated in gambling in Myanmar, and successively lost his personal savings, credit cards, real estate sales and family loans totaling about 170,000 yuan.

  At present, Tian is under the surveillance of Jianghan Oilfield police for violating the relevant provisions of the Criminal Law of People’s Republic of China (PRC) and being suspected of smuggling into the country (border).

  Baoqiang Wang


  Wang Baoqiang ignored the voyeuristic rumors and was busy attending five Spring Festival Galas.


  Wang Baoqiang is a celebrity, but also a busy man. He attended five Spring Festival parties in various places alone. The night before last, Wang Baoqiang was supposed to attend the recording of the "Chinese Stars (Listening to Songs) Spring Festival Gala" of Oriental TV, but he bumped into the rehearsal of CCTV Spring Festival Gala. Wang Baoqiang had to fly to Shanghai the night before last, and then hurried back after recording the program. Although rumors such as "forgetfulness" and "voyeurism" have been aroused recently, Wang Baoqiang is in the excitement of work every day, and he admits that he has no mind to pay attention to these boring things.


  About voyeurism:


  I don’t want to jump into the trap


  Recently, someone posted in various forums, exposing Wang Baoqiang’s "bad" behavior when he was not famous, such as voyeurism.


  When the reporter asked Wang Baoqiang about this, he said, "It seems that whoever has more exposure will have this kind of thing. In fact, people with discerning eyes will know what kind of mentality and purpose this person holds, so I don’t want to pay attention to it, and I don’t have the mind to pay attention to it. I don’t want to jump into their trap. I was born in the countryside, and I don’t understand the truth, but I do understand the truth of being honest and doing things seriously. I didn’t do anything wrong, of course, my heart was frank. "


  About singing:


  I have been unable to find the key.


  Wang Baoqiang will appear in two programs in CCTV Spring Festival Evening this year: the song "Song of Migrant Workers" and the sketch "Bus Concerto" with Feng Gong.


  Wang Baoqiang’s new song "Have Money to Go Home for the New Year" has attracted attention, but it has also attracted criticism. Many netizens think that he "sings too amateur", so that everyone is worried about his performance in CCTV Spring Festival Gala. In this regard, Wang Baoqiang said frankly: "In fact, I have never been able to find a tune in singing, and now it is beyond imagination to complete a song. I think my poor singing is excusable. After all, I am not a professional. During the production of "I have money to go home for the New Year", I got a lot of musical exercises. Now CCTV Spring Festival Evening’s "Song of Migrant Workers" is the second song. I am ready, and it is definitely better than the first song. "


  Last Friday, CCTV Spring Festival Evening held its first rehearsal with machine and makeup. Wang Baoqiang, who was on the stage for the first time in the Spring Festival Gala, was a little at a loss. When he co-starred in a sketch with Feng Gong and others, he just fell down and dropped the microphone in the middle of the performance. Thanks to Feng Gong’s quick wits, the rescue was successful. In this regard, Wang Baoqiang said in an interview with reporters: "It is inevitable that I will be uneasy for the first time on the Spring Festival Evening, but I will adjust slowly, and everyone will definitely see my best state."


  Some time ago, an online poll was conducted on "Who do you want to marry most after watching Soldier Assault", and "Xu Sanduo" was among the best, so what about Wang Baoqiang in life? Wang Baoqiang said shyly, "My brother and my mother said that it seems that many girls do write letters to our home. I have always felt that I have no appearance or figure, and I have nothing to ask for. What everyone likes is actually’ Xu Sanduo’, not necessarily me. " (Wang Linna)

What should I do if I inexplicably become an "emergency contact" for online loans? If you are harassed by the phone, you can record it and leave a certificate.

  "The former boss hasn’t contacted me for two years, but the phone call for debt collection calls me every day. It’s really annoying." "I don’t have any impression of the people who borrowed money. The people who collected it don’t believe it, or they call every day." Recently, many readers reported that because someone listed himself as an emergency contact in the online platform loan, after the borrower overdue repayment, the platform’s collection phone kept calling, which was annoying and didn’t know how to solve it.

  The reporter of Beijing Youth Daily found that there were more than 13,000 complaints about "emergency contacts" on the black cat complaint platform. Almost all of them complained that the loan platform "have no martial ethics" harassed emergency contacts all day, and some borrowers even showed up to ask the platform to stop this operation.

  phenomenon

  Become an emergency contact without knowing it.

  A survey by the reporter of Beiqing Daily found that many people have inexplicably become someone’s "emergency contact" on the online lending platform. Some people said they knew the borrower, but the other party never told themselves about it; Others said that they simply couldn’t remember who the borrower was.

  After receiving the call, Yu Chen (a pseudonym) learned that he was listed as an emergency contact by his former boss. Two years ago, he briefly worked in a small company for several months in administrative logistics. Unexpectedly, the former boss borrowed money from several platforms and didn’t pay it back. He also regarded Yu Chen as an "emergency contact". The call for collection came from both ends every three days, and asked Yu Chen to tell his former boss to pay back the money quickly. But Yu Chen has long lost contact with each other, and I don’t know where to find him. The person who collected the money didn’t listen to the explanation at all, but still persistently harassed Yu Chen. The phone number changed from time to time, and the interception function of the mobile phone was useless, which made Chen Yuyou afraid to answer any strange phone calls for a long time.

  Xiaolin, a company employee, was tired of her ex-boyfriend who had broken up for many years. She said that she was set as an "emergency contact" for online loans by her ex-boyfriend without knowing it at all. In fact, she has broken up with her ex-boyfriend for many years, and the two sides have not contacted each other during this period. When she received the call for the first time, she explained the situation to the other party, but the other party said that she could not contact her ex-boyfriend and could only ask her for help. In the next month, almost every day, collection calls or text messages came in turn, which seriously affected her life.

  Yu Chen and Xiaolin at least had a certain friendship with debtors in the past, and many people didn’t even know debtors, so they became "emergency contacts" inexplicably. Mr. Lin once received a collection call and asked if he knew the borrower and asked him to contact the borrower for handling, otherwise he would have to go through legal procedures. He said "I don’t know" and hung up the phone. As a result, he received dozens of text messages as soon as he put down his mobile phone.

  find

  You can’t apply for a loan if you don’t fill in the emergency contact.

  It is understood that when the borrower applies for an online loan, the platform requires the name and mobile phone number of the emergency contact. If you don’t fill it out, the loan application will not be submitted or the loan amount will be greatly reduced.

  For example, the Privacy Policy of a loan App owned by a consumer finance company with a download of nearly one million clearly stipulates: "In order to provide you with consumer loan services and complete the approval of the application for the use of credit line, we need to fully evaluate your demand for money and risk qualification, so you also need to fill in the loan period and use information (if necessary) and two emergency contact information (name and mobile phone number). If you do not provide the necessary information, you will not be able to successfully submit the loan application and credit line.

  Another loan App stipulates: "In order to enable you to pass the approval of the loan amount of credit institutions more quickly, based on the specific needs and entrustment of credit institutions, you may need to provide us with your educational level, mobile phone number, gender, industry and occupation information after your separate consent. And the photos of the front and back of the ID card, emergency contact information, face information, income information, debt information and residence address (province/city/district) that may be collected according to the verification process. If you refuse to provide us with the above information, we cannot provide you with a higher credit institution quota, but it will not affect your access to a lower credit institution quota. "

  question

  The loan platform does not check with the emergency contact person.

  Since you have to fill in an emergency contact, can you just fill in a name and phone number that doesn’t exist? Netizen Xiao Li said that according to his experience, some lending platforms can do this, even if emergency contacts are filled in at will, it will not affect the quota approval.

  Xiao Li once fabricated the names and telephone submissions of two contacts and successfully obtained a loan of 15,000 yuan on a certain platform. "However, most platforms will let you open access to the address book. When filling in emergency contacts, you must choose in the address book." Xiao Li said.

  Many citizens who inexplicably became emergency contacts said that they had never received a call from the platform for advice or formal notification before receiving the call for collection. If borrowers are not overdue, they will never know that they have been listed as "emergency contacts" for online loans.

  The privacy policy clause of a lending platform App stipulates that the platform needs the borrower to provide two emergency contacts and mobile phone numbers in order to get in touch with the borrower in order to remind him of overdue repayment. At the same time, the platform does not need to contact an emergency contact person for verification, and the lender itself bears the legal risks brought by false information.

  Why can the platform be so "big"? Some insiders in the consumer finance industry have analyzed that the reason why the platform does not verify whether the emergency contact person knows and agrees is that the workload is too heavy, and on the other hand, the borrower does not want others to know that he is borrowing money. In addition, many loan apps can access the address book through user authorization, and can also ensure that the emergency contact is indeed an acquaintance of the borrower. The more important reason is that the emergency contact person is a contact channel, which does not affect the borrower’s credit review and solvency, nor does it assume the role of guarantee.

  statement

  Be careful when filling in the emergency contact and inform in advance.

  However, this does not mean that the platform and borrowers can "do whatever they want" with emergency contacts. Lawyer Xu Guilin, a partner of Beijing Times Jiuhe Law Firm, pointed out that borrowers need to be careful when filling in emergency contacts, and should truthfully inform them of the situation. Because personal information such as mobile phone number is protected by law, others have no right to disclose it without my consent. Especially in the case of malicious harassment of the emergency contact person, if the borrower fails to inform in advance, it may bear corresponding legal responsibilities.

  Xu Guilin suggested that borrowers should list relatives and friends or trusted people as emergency contacts and ensure that they can contact themselves through this emergency contact when necessary. Some borrowers fill in emergency contacts or make up fake numbers, in fact, they want to avoid debts when borrowing money, so that they can "play missing" after borrowing money. This practice can’t reduce the debt, on the contrary, it is very unfavorable to the borrower himself. Because even if the defendant’s whereabouts are unknown and he does not appear in court, the court can directly make a judgment by default, and the lender can also apply for enforcement. At that time, the borrower will face a series of adverse legal consequences, such as fines, detention, and being investigated for refusing to commit crimes.

  pay close attention

  The emergency contact person is not responsible for the guarantee.

  Should the emergency contact bear legal responsibility? On this issue of concern to everyone, Chen Yue, assistant judge of Zhejiang Longyou Court, said that emergency contacts do not have to bear the guarantee responsibility and will not affect personal credit information.

  Chen Yue pointed out that Articles 6 and 13 of the Guarantee Law stipulate that "the guarantee mentioned in this Law refers to the act that the guarantor and the creditor agree that when the debtor fails to perform the debt, the guarantor will perform the debt or assume the responsibility according to the agreement" and "the guarantor and the creditor shall conclude a guarantee contract in writing". It can be seen that to become a guarantor, I need to sign a written guarantee contract with the creditor. Therefore, there is no need to worry about being listed as an emergency contact by the online loan borrower.

  point out

  If you are harassed by collection, you can leave a certificate to report to the police or complain.

  Although the emergency contact person does not need to bear the legal repayment responsibility, no one can stand being harassed by the collection phone for three days. Faced with this situation, how to deal with it?

  Chen Yue, assistant judge of Zhejiang Longyou Court, suggested that, first of all, it is necessary to stabilize the "morale" and realize that the other party’s threats are exaggerated. The purpose of harassing and scaring you is to make you "carry the pot", and the emergency contact person does not have to bear any repayment obligations for the borrower’s loan. Secondly, we should keep good evidence, record the harassing phone call in time, and tell the other party that we have sent total recall, warning the other party not to call again, or we will seek legal relief. If the other party is still adamant, after collecting the evidence, he can report the case to the public security organ or complain to the administrative department for industry and commerce in time.

  Netizen Xiaoyu has been listed as an emergency contact by two unreliable friends. In the process of "fighting wits and courage" with the collection staff, Xiaoyu summed up a set of experiences. He suggested that when you receive a strange phone call for the first time, when the other party says your name and asks if you know someone, don’t answer immediately. You should first find out the identity of the other party and the purpose of looking for you. Once you find out that it is a loan urging company, immediately tell the other party that you don’t know the borrower, that you are not the person he is looking for, that the other party dialed the wrong number, and then hang up. If the other party calls again, yell at him several times and tell him that he has dialed the wrong number, so that the other party will generally stop harassing. If they still insist, they will intercept all strange numbers or set up call forwarding. If the situation is more serious or even threatened, you can call total recall, intercept the phone records, complain to the number operator and call the police at the same time.

What is the level of 100,000-level intelligent driving? Experience BYD Eye of God C

Y car review yautoshow

| Take the facts away and leave the opinions behind |

This program is 7 minutes and 29 seconds long. It is recommended to watch it in Wi-Fi environment.

A while ago, BYD officially announced that "all people will drive with wisdom", which can be said to have dropped a heavy "bomb" on the car circle.

BYD Eye of God Intelligent Driving System, which is dedicated to "intelligent driving and equal rights", is currently divided into three levels of ABC, corresponding to three levels of vehicles, namely, high, medium and low. Whether it is an entry-level seagull or a high-end U8, it has achieved full coverage of intelligent driving.

The Eye of God C system we experienced this time is installed on BYD’s entry-level model, but the actual level of intelligent driving is not entry-level. It adopts the solution of camera and millimeter-wave radar. Although the experience is a non-mass production version, it is quite comprehensive in function and can realize the high-speed and high-order intelligent driving function of the city loop.

On the high-speed loop, its performance is very stable, which is mainly reflected in the aspects of crossing the ramp, actively overtaking and changing lanes, keeping the distance between cars and identifying obstacles. Its driving style belongs to a kind of relatively stable, and it will try to change lanes to overtake and improve traffic efficiency on the premise of ensuring safety.

In the scene of automatic parking, this system can not only park in unmarked parking spaces, but also park in ultra-narrow parking spaces, and the process of parking is relatively smooth, basically less than 25 seconds, which improves the practicability of automatic parking.

At present, all major brands are making efforts to drive the track intelligently, and BYD’s Eye of God has actually given more consumers the opportunity to use smart driving. I believe that the development of smart driving system will become more intelligent and reliable under the background of AI.

Why is strong convective weather the most difficult to report?

  In the flood season, lightning, hail, strong winds and short-term heavy rainfall occurred one after another. Even on June 23 this year, Yancheng, Jiangsu Province suffered a tornado and hail disaster, which all meant the arrival of a high incidence of strong convective weather in China. As the saying goes, "hail hits one line", "rain crosses another road" and "sunrise in the east and rain in the west" all illustrate the characteristics of convective weather.

Comic "Sunrise in the East and Rain in the West"

  Extremely destructive and local.

  The reason why the forecast of severe convective weather is the most difficult of all weather types is to start with what it is and how it happens.

  Strong convective weather refers to severe convective weather that occurs suddenly, changes dramatically and is extremely destructive, often accompanied by thunderstorms, hail, squall lines, tornadoes and short-term heavy precipitation. Strong convective weather is easy to cause disasters, which is destructive and influential. In addition, it has strong locality, small spatial scope and short duration or life span, but it can release powerful forces in a short time. This feature makes every weather phenomenon in the strong convective weather family have extremely strong destructive power and disaster.

  In China, strong convective weather often occurs in spring and summer, and the impact of strong convective weather in these two seasons on cities and rural areas is also different. In spring, hail and strong winds often appear, which are easy to damage buildings and even cause casualties; For agricultural production, it will destroy crops and destroy agricultural facilities. Strong convective weather mostly occurs in summer, during which the temperature is high and the humidity is high, which provides favorable temperature stratification and water vapor conditions for convection. Convective weather often forms in the afternoon to the evening in a day, and sometimes lasts until the first half of the night, which is closely related to the daily change of temperature. In summer, short-term heavy rainfall, thunderstorms and strong winds are often visited. Cities with poor drainage facilities may cause waterlogging, while in areas with weak geological structure, natural disasters such as mountain torrents, landslides and mudslides are prone to occur. Short-term heavy rainfall will also cause rivers and lakes to rise rapidly in a short time, causing floods, threatening people’s lives and property safety.

  Severe convective weather forecast is a worldwide problem.

  The weather system with small scale and rapid development is a difficult point in meteorology. Under the current observation conditions, not only China, but also all countries in the world do not have a comprehensive grasp of its information, so there are still some limitations in the understanding and understanding of this weather. The unpredictability of severe convective weather is a common understanding of experts and scholars engaged in meteorological prediction and scientific research at home and abroad.

  At present, the predictions of possibilities in all countries in the world are only potential forecasts, that is, in a relatively long period of time, convective weather may occur in a certain area. Because of the long time period, only a large-scale forecast can be given comprehensively, which is not particularly targeted. Therefore, in order to provide targeted services, countries all over the world adopt the approach of approaching early warning to strengthen services and guidance.

  Short-term heavy precipitation is a kind of weather phenomenon which is easy to predict in strong convection family. In summer, a lot of rainfall is a mixture of stable precipitation and convective precipitation, and convective precipitation often has a large amount of precipitation in a short time, which also has a great impact. In recent years, the forecast accuracy of short-term heavy rainfall in China has been steadily improved year by year, while the forecast of hourly rainfall intensity has improved the fine level and service ability of severe convective weather forecast.

  Lightning disaster is one of the main disasters caused by severe convective weather. Because of the rapid formation of lightning, it has brought great difficulties to its early warning and forecasting. Researchers and professionals at home and abroad have done a lot of research on short-term lightning forecasting, using mesoscale observation systems, radars, satellites and lightning positioning systems to obtain observation data and numerical forecasting model products, and carried out the development and business operation of lightning weather approaching forecasting technology. For example, the United States can now give the cumulative point probability products after 3 hours. The research and development of lightning early warning and forecasting technology and methods in China has just started in recent years, mainly focusing on lightning approaching forecasting products and lightning early warning and forecasting systems. However, due to the lack of understanding of the physical process of lightning itself, there is no very mature business system so far.

  Tornadoes are small-scale weather systems or small-probability events with strong randomness in time and space. At present, most meteorological detection equipment and detection systems cannot effectively monitor and track the occurrence and development of tornadoes. Therefore, even in the United States, although tornado forecasting and monitoring have been carried out for many years, the distance between meteorological monitoring stations is decreasing year by year, and the radar network is becoming more and more perfect, it is still difficult to accurately forecast and the early warning time is still limited.

  There are also great difficulties in forecasting hail. As long as the atmospheric conditions are suitable, there will be hail everywhere. At the same time, the characteristics that indicate the appearance of hail are easily concealed by weather characteristics such as heavy precipitation, thunderstorm and strong wind, which makes the forecast more difficult. At present, numerical weather forecast can give some meteorological factors related to hail formation, but it can’t directly give the final forecast result of hail size. The forecast of hail is mainly obtained by the forecaster’s grasp of various weather elements and comprehensive analysis based on historical data. At present, the focus of hail forecast is to predict the size of hail, which involves more factors and more complicated mechanisms. At present, it can only be a rough estimate and cannot be applied to business. Meteorologists try to identify the size of hail particles by radar echo, and judge the probability of hail of various sizes and the probability of strong hail by hail detection algorithm, and estimate the maximum hail diameter. This method can be used to forecast the weather within one hour, but it is not mature at present, and its effect needs to be tested. In the hail forecast, at present, we can only rely more on Doppler radar for continuous monitoring, and try our best to find the hail characteristics near the strong convective weather, and release them to the public in time through early warning.

  A variety of strong weather forecast and early warning products

  Weather forecast can be divided into immediate forecast, short-term forecast and short-term forecast from the time limit of forecast service. The near forecast is the weather forecast within 0-2 hours, the short-term forecast refers to the weather forecast within 2-6 hours, and the weather forecast over 6 hours is classified as short-term forecast. There are forecast and early warning products for severe convective weather in these three kinds of time-limited forecasts.

  At present, the Central Meteorological Observatory can provide all kinds of severe convective weather forecast products for up to 72 hours, issue severe convective weather warning before severe convective weather occurs, and give early warning of possible severe convective weather according to the time and scope. Meteorological departments at all levels will also issue early warnings for a certain weather phenomenon, such as lightning warning, hail warning, gale warning, etc.

  Aggregation forecasting products help forecast and early warning.

  Because the system causing severe convective weather belongs to small and medium-scale weather system, it is difficult to be captured by conventional meteorological observation network, so unconventional observation data (automatic station, radar, satellite, lightning global positioning system, wind profiler radar, etc.) and their fusion, assimilation data and mesoscale numerical model data are the main data basis for short-term and imminent forecast of severe convective weather. At present, the United States, Britain, Canada, Australia, France, Japan, South Korea and China have established short-term forecast systems for severe convective weather.

  Ensemble forecasting products provide forecasters with more possibilities for their reference. Convection-scale ensemble forecasting system has higher temporal and spatial resolution, can describe the fine structure of weather system and assimilate more information, and the physical process is closer to the actual situation. Therefore, this system can better simulate the local disastrous weather on a smaller scale and accurately forecast the convective weather system with a larger vertical spatial scale and more vigorous development. In the early warning of severe convective weather, the rapidly updated geostationary meteorological satellite image as an important auxiliary means of monitoring, combined with the radar image as the main monitoring tool, can help forecasters release early warning information for a longer time in advance.

Interview with Wang Jingwu, Vice President of ICBC: Commercial banks face great challenges in climate risk management.

Zhongxin Jingwei, November 1st (Wang Quanbao, Wei Wei) It is one year since China officially put forward the goal of "double carbon". In the practice of promoting "double carbon" for one year, the role played by finance has become more and more prominent.

"ICBC’s green loan balance has reached 2.15 trillion yuan, and all major indicators of green investment and financing are in a leading position in the market. The green and low-carbon transformation of investment and financing has achieved remarkable results." Recently, Wang Jingwu, vice president of China Industrial and Commercial Bank, revealed this in an exclusive interview.

Grasp the rhythm of investment and financing transformation

Zhongxin Jingwei: In the past year, banks have been actively deploying "carbon finance". In your opinion, what challenges does the banking industry currently face in helping achieve the goal of "double carbon"?

Wang JingwuAchieving peak carbon dioxide emissions and carbon neutrality is an extensive and profound systematic economic and social change, which means that China’s economic and social development will undergo a comprehensive green transformation, and the energy structure, economic structure and industrial structure will all undergo major changes, which put forward new requirements for commercial banks’ risk management ability and management ability.

What we want to make clear is that commercial banks face great challenges in climate risk management. It can be said that climate risk is an important consideration of systemic financial risks.

Specifically, the challenges are divided into two aspects: first, the assessment and response to climate risks are facing great challenges, banks have not fully understood the correlation between environmental change factors and financial risks, and their understanding of physical risks and transition risks brought about by medium and long-term climate change is not enough, so risk assessment and stress testing methods need to be studied; Second, the basic work of climate risk prevention needs to be improved, such as the international and domestic unification of standards such as green finance and brown assets, the acquisition of corporate climate risk and carbon emission data information, etc. Banks are facing the challenge of information asymmetry in the process of preventing corporate environment and climate risk.

Zhongxin Jingwei: China officials have proposed that carbon dioxide emissions should reach the peak by 2030 and strive to achieve carbon neutrality by 2060. The service "30 60" target puts forward higher requirements for commercial banks. What business transformation does the bank need to make in order to help peak carbon dioxide emissions achieve the "30 60" goal of carbon neutrality?

Wang JingwuIn the long run, banks need to promote their own operations and low-carbon transformation of assets. In terms of low-carbon transformation of self-operation, the office and business premises of banks are relatively scattered, and the carbon emissions are relatively wide.Low-carbon transformation needs systematic planning and institutional arrangements, among which the first task is to find out the background of its own carbon emissions and conduct its own operating carbon accounting..

In the aspect of low-carbon transformation on the asset side, banks need to deeply study the transformation of China’s economic structure, energy structure and industrial structure under the background of peak carbon dioxide emissions and carbon neutrality, and its impact on medium and long-term investment and financing risks, especially pay attention to grasping the rhythm of investment and financing transformation, and how to handle the relationship between transformation and security, short-term and long-term, and emerging industries and traditional industries.

Help the national industrial transformation

Zhongxin Jingwei: In the past year, what efforts has ICBC made to help achieve the goal of "double carbon"?

Wang JingwuFocusing on the goal of "double carbon", ICBC has fully implemented the national decision-making arrangements on "double carbon" work, relied on the long-term accumulated experience and advantages in the field of green finance, and based on the low-carbon development trend of China economy, adjusted the investment and financing layout in a forward-looking way, and continued to promote the low-carbon transformation of investment and financing, climate risk prevention and control, and carbon financial product innovation, so as to contribute to serving the national goal of "double carbon" and helping the national industrial transformation.

First, steadily promote the low-carbon transformation of investment and financing.. On the one hand, ICBC has continuously increased its support for low-carbon industries around four main lines: low carbon, zero carbon, carbon reduction and negative carbon. In the field of "zero carbon" and "low carbon", we will focus on supporting industries such as clean energy, green transportation, green building and green manufacturing; In the field of "carbon reduction", actively support enterprise energy-saving transformation, energy efficiency improvement projects and energy-efficient equipment; In the field of "negative carbon", we actively support frontier projects such as carbon capture and the construction of carbon sink forests. Taking the energy sector as an example, ICBC’s clean energy loans have become the main part of loans in the power industry, and the proportion has increased significantly. In particular, new energy power generation loans such as wind power and photovoltaics have grown rapidly, and the loan balance and proportion have obvious advantages in the industry.

On the other hand,ICBC actively supports the low-carbon transformation and development of "high carbon" industries.For high-carbon industries such as "two highs", we will continue to implement the credit policy of "customer classification, security and pressure", support key enterprises to save energy and reduce emissions, update equipment, and continue to withdraw from backward production capacity.

Secondly, innovate to build a carbon financial product system.. ICBC launched the first batch of "carbon-neutral" bond investment and financing business, and underwritten 12 "carbon-neutral" bonds, leading the market in underwriting scale. ICBC actively participated in the National Green Development Fund, fully docked the construction of the national carbon market, and innovatively supported the construction of the green financial reform and innovation pilot zone, and achieved positive results.

This year, ICBC actively innovated financial products in the capital market, and launched the first ESG theme fund in the market, the "carbon neutral" asset allocation index, and the first wealth management product with the theme of green finance.

Third, continue to strengthen climate risk management.. ICBC has incorporated climate risk into comprehensive risk management, continuously promoted climate risk management among various risks such as credit risk, market risk and strategic risk, embedded climate risk elements into the whole process of investment and financing policies and business management of various industries, and adopted reasonable risk control measures for high-carbon enterprises with prominent climate risks.

Recently, under the guidance of the People’s Bank of China, ICBC has also completed the pilot work of climate risk stress testing and achieved good results.

Guiding the flow of credit resources to green areas is one of the key tasks.

Zhongxin Jingwei: As the leader of state-owned banks, what comparative advantages does ICBC have in green finance?

Wang JingwuIt can be said that green finance is the traditional advantage of ICBC, with its early start, rich background and solid foundation. ICBC has integrated the requirements of green finance into development strategy, corporate governance, policy system, business process and risk management, and established a perfect green finance development system, which has effectively played the role of pioneer and leader in the development of domestic green finance.

In recent years, ICBC’s green investment and financing scale has continued to lead the industry. By the end of June, the balance of ICBC’s green loans exceeded 2 trillion yuan, reaching 2.15 trillion yuan; The balance of green bond investment, green non-standard agency investment and green lease financing is more than 400 billion yuan, and the cumulative issuance of green financial bonds is nearly 10 billion US dollars. The main indicators of green investment and financing are in the leading position in the market.

First, the green financial strategy promotion system is perfect. As early as 2007, ICBC took green finance as its development strategy and vigorously promoted the construction of green credit from top to bottom. China Industrial and Commercial Bank’s Green Credit Development Strategy, published in 2015, clearly regards the promotion of green credit construction as one of the important long-term strategies of the whole bank, and is committed to building a leading international green credit bank and becoming a green bank with a good international reputation. Over the years, ICBC has continuously improved the governance structure of green finance, and formed a green financial strategy promotion system with the overall leadership of the Board of Directors and the Green Finance Committee, coordinated division of labor among all departments, active innovation of branches and full participation.

Second, the green financial policy system is solid and effective. ICBC has formulated investment and financing policies in 16 sectors and 50 industries, fully highlighted the "green" orientation, and continuously increased the support and control of differentiated policies. In the enterprise dimension, the enterprise technology, environmental protection, energy consumption and other indicators are embedded in the key industry customers and project selection criteria; In the industry dimension, key areas such as clean energy, green transportation, energy conservation and environmental protection will be positioned as active or moderate entry industries, and differentiated management measures such as economic capital occupation, authorization, pricing and scale will be supported.

Third, the forward-looking research on green finance has achieved remarkable results. ICBC took the lead in publishing the results of environmental risk stress test among domestic peers, and it is also one of the earliest financial institutions in the world to carry out environmental risk stress test research. ICBC has also released ESG index and "One Belt, One Road" green finance (investment) index, which provide methods for the global financial industry to quantify environmental risks. In addition, ICBC also took the lead in the pilot project of environmental information disclosure under the framework of China-UK dialogue, and explored the environmental information disclosure standards of the financial industry.

Fourth, international cooperation in green finance is vivid. In 2017, under the guidance of the People’s Bank of China, Industrial and Commercial Bank of China launched the "Belt and Road" inter-bank cooperation mechanism (BRBR) in propose to create. In 2018, it assisted the Green Gold Committee and the City of London to jointly draft the Belt and Road Green Investment Principles (GIP) and became the first signing institution. In addition, ICBC actively contributes to the formulation of international rules with the help of relevant UN platforms. In 2018, as the only invited Chinese bank, it participated in the "Responsible Banking Principle" project initiated by the financial initiative of the United Nations Environment Programme and became the first batch of contracted banks. In 2019, as the only Chinese-funded institution, ICBC was invited to join the Global Investor Alliance for Sustainable Development (GISD) initiated by UN Secretary-General Guterres.

Zhongxin Jingwei: Green credit plays an important role in promoting green economic transformation. How does ICBC guide credit resources to the green field?

Wang JingwuGuiding the flow of credit resources to the green field can be said to be a key point of ICBC’s green finance work. Industrial and Commercial Bank of China has issued a series of incentive and safeguard measures, and the intensity is still increasing.

The differentiated investment and financing policy I mentioned earlier is one of the important aspects. In addition, ICBC has arranged a variety of incentive mechanisms.

First, make an annual plan for green loans, arrange a certain special scale of green loans, and give priority to ensuring the credit supply of green industries. The second is to implement internal transfer price (FTP) incentives for green loans. Third, strengthen the assessment of green credit, incorporate green credit into the performance assessment index system of branches, and focus on the assessment of key indicators such as the proportion of green loan balance and the growth rate of green loans. Fourth, carry out special audits of green credit, regularly select some branches to conduct special audits of green credit every year, and objectively evaluate the implementation of green credit policies by branches.

Prevention and control of environmental and social risks is an important part of green finance.

Zhongxin Jingwei: Environmental and social risks are important contents of green finance work. How to improve the ability of environmental and social risk management?

Wang JingwuPrevention and control of environmental and social risks is an important part of green finance, which is of great significance to restrict investment in ecologically destructive projects, guide financial resources to invest in eco-friendly fields and promote financial stability.

In this regard, it can be said that ICBC has established a relatively complete environmental and social risk management policy, system and process, strictly abides by the red line of ecological protection, the bottom line of environmental quality, the online utilization of resources, land, health, safety and other hard constraints, and strictly formulates environmental access standards and risk control measures.

First, implement green classified management of investment and financing.According to the "green" degree of investment and financing and the degree of environmental and social risks, investment and financing are divided into four levels and twelve categories, and differentiated investment and financing policy management is implemented.

The second is to strengthen risk management in environmentally sensitive industries., reasonably control the financing of environmentally sensitive industries, improve the requirements for key indicators such as enterprise technology, energy consumption, technology and environmental protection, and proactively withdraw from corporate financing with high environmental and social risks, especially for industries involving heavy metal emissions. Strict investment and financing control regulations have been formulated.

The third is to implement the whole process management of environmental and social risks., in the due diligence, examination and approval, contract signing, fund disbursement, post-loan management and other links, the corresponding environmental and social risk management requirements are embedded.

Fourth, intelligent management of investment and financing environment and social risks.. For many years, ICBC has always adhered to the mechanism of enterprise risk information collection and prevention and control that the head office and branches are responsible for. Recently, ICBC pioneered an intelligent management system for environmental and social risks in the industry, and used big data analysis to realize intelligent prompt and control of environmental and social risk information.

Zhongxin Jingwei: What are the explorations and attempts in financial technology to help environmental and social risk management?

Wang JingwuWith the rapid development of financial technology, it can be said that financial technology has great potential in environmental and social risk management. ICBC continues to explore and innovate in this respect. The recently launched intelligent management system for environmental and social risks is a case. This system can automatically complete the collection, collation, distribution and transmission of risk information, greatly saving manpower and material resources, and truly making risk management timely, accurate and effective.

In the future, ICBC will also explore new fields such as investment and financing carbon accounting, ecological protection red line map and climate risk identification by means of financial technology, and continuously improve its environmental and climate risk management capabilities by means of new technologies such as big data, Internet of Things and artificial intelligence.

Zhongxin Jingwei: Looking forward to the future, what plans does ICBC have in the "double carbon" work of financial services?

Wang JingwuIt is an important strategic task for financial institutions and an inevitable requirement for their long-term development to implement the deployment requirements of "peak carbon dioxide emissions and carbon neutrality". In the future, ICBC will make efforts in the following five aspects:

The first is to strengthen scientific planning. Consistent with the inherent requirements of the national "double carbon" goal, we should consider the relationship between green and low-carbon transformation of investment and financing, energy security and financial stability, respect the objective laws of economic and social transformation, and scientifically grasp the pace of work.

The second is to strengthen service entities. Rationally allocate resources, actively support the development of green and low-carbon industries, reasonably control the financing of high-carbon enterprises, and effectively serve the low-carbon transformation and high-quality development of the real economy.

The third is to strengthen overall development. Co-ordinate the work of double carbon, green finance, ESG investment and other related work, co-ordinate the work of double carbon under the framework of green finance, and rely on China’s relatively perfect green financial system to carry out the work.

The fourth is to strengthen system promotion. Coordinate the financial support of green and low-carbon industries and the prevention and control of climate risks in investment and financing, actively improve their carbon performance and vigorously promote the low-carbon transformation of their own operations.

The fifth is to strengthen exploration and innovation. Strengthen research on new modes and formats in the fields of carbon finance and climate investment and financing, and provide all-round and distinctive innovative products and services. (Zhongxin Jingwei APP)
