Enhance the sense of innovation and do scientific research with taste.

Innovation is the key to scientific research. According to different research attributes, innovation has different types: original innovation, cutting-edge innovation, technological innovation, integrated innovation, applied innovation and so on. No matter what kind of innovation, the innovation subject needs to have innovative consciousness, put forward innovative ideas, carry out innovative practice and produce innovative results. Innovation consciousness is the premise of scientific innovation activities. Researchers should consciously enhance their innovation consciousness, not follow others’ advice, follow the crowd and chase hot spots, think independently, dare to be the first and find a new way, and on the basis of predecessors’ work, through profound insight, rich imagination, careful thinking and concrete practice, find problems, raise problems and then solve them.

Academician Gao Dingsan, the founder of the Institute of Electronics of Jida University, was keenly aware of the importance of semiconductor devices in the mid-1950s, and took the lead in developing high-power germanium rectifiers and point-contact germanium diodes in China, which started the research of semiconductor devices in China. This innovative consciousness and spirit can be passed down and carried forward among the new generation of young scholars. Professor Feng Li, winner of the National Outstanding Science Foundation and State Key Laboratory of Supramolecular Structures and Materials, used the solid physical and device foundation laid during his undergraduate and doctoral years in the School of Electronics and combined with his years of research practice in the field of organic optoelectronics, put forward and verified a new concept of organic electroluminescence with two-line exciton emission, which broke through the limitations of closed-shell molecules of organic electroluminescent materials, opened up a new field of free-radical open-shell molecular electroluminescence, and wrote a strong stroke for China scholars in the field of organic optoelectronics.

Innovation needs taste. Taste is awe of the profession, demanding of oneself and respect for peers. Taste also reflects the pride, persistence, perfection and craftsman spirit of researchers. Teachers in Jilin University should cultivate innovative consciousness, carry out tasteful research, contribute to mankind, serve the country, serve the society and achieve themselves.

Adhere to the spirit of seeking truth from facts and do meaningful scientific research.

Seeking truth from facts is the key to scientific research. Seeking truth is to pursue scientific truth, discover real phenomena, obtain real data, reveal the essence and connotation of science, and then expand the boundary of human cognition, and use it to transform the world and make it a better place. The process of seeking truth from facts is a painful and happy one, and this process will inevitably encounter many difficulties and challenges, some of which are confusion of thinking methods, some are lack of hardware conditions, and some are shortcomings of the research team. However, no matter what kind of situation you encounter and what kind of situation you are in, as long as you are realistic and do not change your mind, you will open roads and bridge rivers, overcome all kinds of difficulties and obstacles, and finally reach the other side of scientific truth.

Jilin University has an academic tradition of seeking truth from facts, and the old president of Tang Aoqing is a model of seeking truth from facts. In 1986, Mr. Tang Aoqing stepped down as the principal and became the director of the National Natural Science Foundation of China. In addition to his busy management work, he still insisted on the research of polymer solidification theory and scale. In five years, he wrote 104 personal letters to his collaborators and doctoral students in Beijing to discuss the progress of research and the problems he encountered. As early as 1960s, Mr. Tang Aoqing got the sol-gel distribution formula by using the theory of dynamic random branching, and he wanted to get the polymer solidification theory on this basis. However, when dealing with the problem of internal Aa cross-linking, Mr. Tang found the shortcomings of previous work. In his letter to his collaborator, he wrote: "I found that there was an error in the previous derivation of the problem of internal Aa cross-linking. I was aware of this problem when I visited West Germany. After reading your letter, the problem became clearer. I re-derived the formula and attached it. Please ask Comrade Zesheng to do some concrete calculations and verify it to see if it is correct." (Quoted from Tang Aoqing and His Disciples, Xiamen University Press, November 2015, p. 161) Between the lines, Mr. Tang’s scientific spirit of seeking truth in learning is reflected, which is a model for our people to learn, and a scholarly character and spiritual wealth that Jilin University should cherish and inherit.

Professor Liu Shiying, the late famous optoelectronics scientist in the Institute of Electronics, is also a good teacher who is realistic. Mr. Liu is a founding veteran of the Institute of Electronics and one of the founders of the State Key Laboratory of Integrated Optoelectronics. He has made outstanding research achievements in integrated circuits, semiconductor lasers, integrated optoelectronics and organic optoelectronics. He is not only active in thinking, rigorous in academic research, and realistic, but also teaches young teachers and students by example. Whenever young teachers and graduate students report on their scientific research work, Mr. Liu will ask about the details of the experiment and the physical nature of the experimental phenomenon. The young teachers and graduate students who were questioned felt humiliated and embarrassed at that time. However, after they calmed down, they will feel that this kind of realistic style of study is very important, and they will strictly demand themselves and then teach them to their own students, gradually forming a rigorous and realistic style.

Stick to academic integrity and be a convincing good scholar

Academic integrity is the life of academics and also the life of scholars. Academic misconduct or academic anomie not only destroys the atmosphere of academic community, leads to the prevalence of unhealthy trends, but also misleads and interferes with the research of other scholars. If papers based on false data are published, peer scholars will track, repeat and verify these results. When they don’t get the same or similar results, peer scholars will first suspect that there is something wrong with their own experimental methods or details, thus spending a lot of time, energy and resources to repeat experiments, resulting in a lot of waste of time and resources, which is a direct damage to peer scholars. Therefore, adhering to academic integrity is the basic requirement and professional bottom line of scientific research teachers.

In recent years, the alienation tendency of evaluation criteria has led to impetuous wind. Aiming at publishing papers with high impact factors, keeping up with hot spots, frequently switching research directions, not deeply exploring experimental phenomena, not excavating the scientific essence and connotation, and lacking in depth and systematicness in research are also bad habits that need to be broken urgently. Every year, I spend more energy on revising project applications for some teachers. Most of the applications are novel and innovative, and the key scientific issues are concise and accurate, and the research content and scheme are concrete and feasible. The application is carefully written and can express the research to be carried out in the demonstration with accurate language and strict logic. However, some teachers’ project books are in contrast with the published research papers. The reason is that these teachers only pay attention to the appearance of research, neglect to ask and think about the connotation of their own research, and lack deep insight and understanding of the development trend in this field. Pursuing scientific truth and carrying out innovative research, like teaching and educating people, is a sacred and lofty cause and an important mission of universities. We should cultivate the sense of innovation, adhere to the spirit of seeking truth from facts, adhere to academic integrity, and be a good teacher with taste, character and bottom line.

　　Recently, "end-to-end" has been on fire in the car circle! Tesla’s benchmark demonstration effect based on the "end-to-end" FSDV12 (fully autonomous driving) scheme, and the rumors of joining China, have driven companies such as "Wei Xiaoli" and service providers such as Huawei and Horizon to turn around and add end-to-end autonomous driving technology.

　　The so-called "end-to-end" actually comes from the concept of deep learning, and English is "end-to-end (E2e)", which means that through an AI model, the final result can be output as long as the original data is input. When it is applied to the field of automatic driving, it means that only one model is needed to convert the sensing information collected by sensors such as camera, millimeter-wave radar and laser radar into specific operating instructions such as the steering angle of the vehicle, the stepping depth of the accelerator pedal and the braking strength, so that the vehicle can realize automatic driving. In the words of He Xiaopeng, the founder of Xpeng Motors, it is "very silky" and more like "human drivers driving".

　　Previously, most autonomous driving systems on the market were traditional modular, that is, a mix-and-match system with artificial and intelligent worlds: perception relied on neural networks, and planning and control used algorithms designed manually by humans. The advantage of this system is that the division of labor is clear, and it is convenient to check and solve the defects in modules. But the problem is that this modular automatic driving system performs well in relatively simple driving tasks, and its ceiling is obvious in the face of complex driving tasks. Even the so-called advanced intelligent driving function of the city, which is far ahead, still has a sense of machinery, and it will also stop when it merges into the expressway and passes through a large intersection.

　　Considering that the core challenge of autonomous driving is to solve endless edge scenes, the cost and time of solving the infinite long tail problem with limited manpower are incalculable, and data and modeling have become an inevitable trend. However, end-to-end, it is also a difficult technical job that needs careful polishing by the master.

　　On the one hand, end-to-end needs massive high-quality data "feeding" training. Unlike the big language model, which can crawl a large amount of text data on the Internet for training, the cost and difficulty of obtaining video data for end-to-end intelligent driving are extremely high. Take Tesla as an example. At present, its FSD has accumulated more than 20 million human driving video clips, and the data collection cost of this scale only needs 5 billion to 8 billion yuan.

　　On the other hand, end-to-end needs the support of powerful computing power. Automatic driving involves technologies and solutions such as lidar, image perception and V2X vehicle-road coordination. Powerful computing power is not only conducive to real-time processing of massive data, reducing data transmission delay, but also better supporting the whole scene for smart cities, smart transportation, high-level autonomous driving and so on. However, the computing power growth of domestic enterprises such as Huawei BU, Baidu Jiyue, Weilai, Ideality, Geely, Great Wall, Tucki, etc. are currently facing major bottlenecks.

　　The problem is that the constraints of computing power and data will significantly affect the development of the algorithm. Although UniAD, an end-to-end autopilot model put forward by domestic academic circles, won the Best Paper Award of CPVR in 2023, which provides a reference direction for domestic enterprises, but UniAD developed under the open-loop verification system and small sample data still needs some engineering transformation and large-scale data training.

　　In addition, the upper and lower limits of the autopilot system will be enlarged end to end. Because the end-to-end construction is a neural network black box, in the process of obtaining a higher upper limit, some of the interpretability of the traditional module scheme is transferred. How to retain the interpretability in the autopilot system and characterize the rules that should not be overstepped, such as don’t run a red light, into the neural network to ensure the end-to-end application and evolution safely, will also be an important topic for regulatory engineers.

　　There are two routes to climb Mount Everest: one is the northern slope of Tibet, China, and the other is the southern slope of Nepal. Whether you choose to climb from the south slope or the north slope, you will eventually reach the same peak. This is similar to the current development path of autonomous driving. Although it is still difficult to determine that end-to-end is the optimal solution or final solution of autonomous driving, this does not hinder the innovation and exploration of enterprises. After all, end-to-end can handle extreme cases better than traditional modular methods, and it represents a more efficient way to reduce the dependence on manual coding. Based on this path, perhaps autonomous driving can lead to a higher stage. (Yang Zhongyang)

Due to the supplier’s production deviation, the mechanical joint between the spline shaft on the transmission shaft and the ball cage on the universal joint is not completely fixed for some vehicles within the scope of this recall, resulting in that the safety clamp spring at the mechanical joint cannot be completely locked in a specific fixing slot, which may damage the universal joint of the transmission shaft, and the damage degree will increase with time. This will lead to unbalanced transmission of the transmission shaft, resulting in jitter, which will then be transmitted to the bottom of the vehicle. In extreme cases, jitter will affect the SRS (Auxiliary Protection System) control unit assembled above the gearbox, and it will be misjudged by the control unit as acceleration or deceleration caused by a collision accident, and the front airbag will be triggered incorrectly, increasing the risk of injury and collision of front passengers; In addition, if the owner continues to drive the vehicle for a long time by ignoring abnormal conditions such as abnormal noise and jitter, the parts will be worn to a certain extent, which will affect the power transmission of the vehicle and even cause power loss, which has potential safety hazards.

Fujian Benz Automobile Co., Ltd. will check whether the transmission shaft is within the affected production date range for the vehicles within the recall range through its authorized service center, and if so, replace the transmission shaft to eliminate potential safety hazards.

Fujian Benz Authorized Service Center will notify relevant users of the recall by registered mail.

Original title: "Emergency recall! Attention Puyang car owners! 》

Read the original text

　　　Yue Kaihan, a German student majoring in China from Zhejiang University who graduated with a master’s degree this year, spent nearly 100 days riding a bicycle from Mohe City, Heilongjiang Province to Sanya City, Hainan Province, with a journey of more than 5,800 kilometers.On the way, he would ask the strangers he met along the way: "What is your China dream?"

　　The answer he got from Wan Li Road becameHis master’s thesis — — The Chinese Dream of the Common People.

　　"The school has always been very supportive of students majoring in China to get out of the classroom and books and get to know the real China through field visits. Yue Kaihan proposed to the instructor to get to know China by riding, and focused on the common people in China ‘ Chinese dream ’ Our understanding has been supported and encouraged by our teachers. The school also specially applied for the project funds for his research. " On November 27th, Lu Yuan, a teacher of China Studies Center of Zhejiang University, told The Paper.

　　Exploring the "Chinese Dream" of Ordinary People by Riding

　　Yue Kaihan’s Chinese name was taken by a friend. His real name is Jorg, and he is 28 years old. He came to China for the first time in 2011. In one year, he learned to use chopsticks and learn Chinese in Chengdu, Sichuan. Out of interest in China culture, Yue Kaihan went to China Center of Zhejiang University to study for a master’s degree in China in 2015.

　　It is understood that the China Studies Center of Zhejiang University has started to recruit and train masters in international cooperation since 2010. Up to now, it has recruited more than 350 international students from more than 50 countries around the world. This major is designed to systematically study China’s social, political, economic and historical degree courses in English, so that students can improve their Chinese level, feel China culture, integrate into China society, and carry out research on China issues.

　　Lu Yuan introduced that China studies is not limited to the classroom, but also encourages students to go deep into China society and let them contact ordinary Chinese, such as farmers and citizens. Through interviews and investigations, they find the problems faced by China society and propose solutions. To this end, on the basis of classroom teaching, each course will set up a field investigation class, and the examination is not limited to the examination paper, but more in the form of project report.

　　"Yue Kaihan thought is mature, have their own ideas, action, he has been to many cities in China. Before the opening report of the paper, he proposed to the instructor to learn about China by riding. The instructor suggested that he combine the research with the topic and write the riding experience as a paper. " Luyuan told The Paper.

　　　Yue Kaihan said that he first heard the word "Chinese Dream" in 2013, and now it has become a high-frequency word in China.But he doesn’t know what the "Chinese dream" is in the eyes of ordinary people in China. To solve this problem, we must visit historical sites and modern buildings in China, visit cities, stop in the countryside, climb mountains and rivers, and ask questions to people of different ages and classes.He also wants to learn more about China.

　　He chose cycling to get to know China, which he thought was natural, environmentally friendly and friendly, and also had high flexibility and freedom. Two months before departure, he conducted assault training, from riding 30 kilometers to 80 kilometers, and then riding from Hangzhou to Shanghai.

　　In order to make the "Riding China" plan not affect his studies, Yue Kaihan completed all the postgraduate courses in one year. He also planned his cycling route very rigorously — — It spans 12 provinces (autonomous regions and municipalities directly under the Central Government) in China, with a total distance of over 5,800 kilometers. He chose Arctic Village, Mohe, Heilongjiang as the starting point of his journey, which is the northernmost place in China, and ended in Sanya, Hainan, passing through big cities such as Beijing and Wuhan, as well as historical sites such as Shaolin Temple and Yin Ruins, as well as many small towns.

　　　Open WeChat official account to write cycling experience.

　　　On May 1, 2016, Yue Kaihan took the second-hand simple folding bicycle given to him by a friend, carried a big backpack, got on the train from Hangzhou to Harbin, and then took the bus to Mohe Arctic Village.

　　　His big backpack is equipped with tents, inner tubes, pumps, cloth strips and other items, as well as electronic products such as mobile phones, tablets, charging treasures and cameras. There are only two sets of clothes to change.

　　　Before the trip, Yue Kaihan also registered on WeChat WeChat official account "Where is Brother Yue going" to record what he saw during the trip. On the day of the trip, he wrote: "If I will pass through the city where you live, please contact me. I am very happy to know your city, listen to your story, and be a couch potato in your home. "

　　　Every time he goes to different cities and meets impressive people, he will write these stories in WeChat official account. For example, on the 57th day of cycling, he was in the birthplace of Chenjiagou Tai Ji Chuan in wen county, Henan Province, and Mr. Li, a teacher from Tai Ji Chuan, provided him with free accommodation. During the conversation, Yue Kaihan found that Mr. Li was originally a solar engineer … …

　　On the way, Yue Kaihan will focus on the differences between urban and rural areas in China, and the different concerns of young people and the elderly. He found that older people are less concerned about economic interests and have no desire to earn a lot of money. They are more concerned about the stability and fairness of the whole society. Young people will talk more about education and personal future development, and occasionally mention personal interests, fitness and other issues. The difference between urban and rural areas is obvious. People in the village want to live a happy and peaceful life, while people in the city want to do what they want.

　　　Asking people along the way "What is your dream of China" is a question that Yue Kaihan must ask everywhere. He repeated this question hundreds of times.

　　　He thinks the answer he got is very true.The "Chinese dream" of a female restaurant owner in Mohe Arctic Village is to help the elderly improve their quality of life and reduce the burden on the younger generation. A worker in Yangshuo, Guangxi dreams of a well-off and rich material life; A computer student in Changchun University hopes to realize his personal ideal and make contributions to society … …

　　Yue Kaihan came to the conclusion that in the eyes of most ordinary people, the "Chinese dream" is related to the improvement of living environment, the prosperity of the country, social harmony and social reform. The "Chinese dream" of individual citizens mainly focuses on practical aspects, such as wealth, happiness, self-realization and family. Officially, the "Chinese Dream" is the rejuvenation of the whole country and nation. Even though the people are vague about the specific ways to realize their dreams, they all agree that only the rejuvenation of the nation can bring happiness to the small family.

The business review of the 2022 annual board of directors of Kede CNC is as follows:

　　I. Discussion and analysis of business conditions

In 2022, the company around the annual business objectives, relying on the advantages of the whole industrial chain and product technology, continued to strive to open up the market, increase production capacity, break through the influence of various unfavorable factors, and maintained a good momentum of steady growth. The income from main business, net profit after deducting non-recurring gains and losses, new orders and output all increased rapidly. The net profit attributable to owners of the parent company decreased slightly year-on-year due to the higher government subsidies included in non-recurring income in the same period of last year.

(a) the main business situation

In 2022, the company’s operating income was 315 million yuan, a year-on-year increase of 24.39%; The net profit attributable to shareholders of listed companies was 60,453,800 yuan, a decrease of 17.04% compared with the same period of last year. The main reason for the decrease in net profit was the high amount of government subsidies included in the current non-recurring gains in 2021, which had a great impact on the current net profit growth (specifically, the impact of non-recurring gains and losses on net profit in 2022 was about 22,264,600 yuan, and the impact of non-recurring gains and losses on net profit in 2021 was about 22,264,600 yuan). The net profit after deducting non-recurring gains and losses was 38,189,100 yuan, a year-on-year increase of 45.12%; Gross profit margin of main business is 42.40%; The output of the whole machine was 230 units, up 45.57% year-on-year; During the reporting period, new orders increased by 30% year-on-year.

(2) New breakthroughs have been made in market expansion.

The company insists on import substitution as the core, and on the basis of deepening cooperation with original customers and deepening and strengthening the aerospace field, it strives to open up new fields, new customers and other industrial fields. In 2022, the company made new progress in overseas orders, new energy vehicles, energy, knives, machinery and equipment.

The company’s products are characterized by the customization function on the general platform, so as to meet the individual needs of different customers. Therefore, the company generally adopts the production mode of "fixing production by sales", based on the order contract, carries out product design and development according to the needs of users, formulates the process route, and organizes production in combination with the delivery plan and production capacity. For the standard components, based on market forecast and historical order trend in the same period, moderate pre-production will be carried out.

In terms of production organization, the company generally follows the principle of "fixing production by sales and keeping reasonable inventory of standard components", and according to the sales plan and actual sales situation, formulates the production plan and issues it to the production workshop to organize production. For highly customized products, because different users have different requirements on product configuration, performance, parameters, etc., the company will deliver the customized requirements to the R&D center for design and development. After both parties reach an agreement, they will sign a sales contract for stocking and production.

In terms of production operations: the production department strictly implements the process control requirements determined by the design department and the production technology center, and implements the production plan. The Quality Management Department sets up key control points according to product performance requirements and related processes, and formulates control items and target values, and supervises production operators to strictly implement process requirements and operation instructions.

The company entrusts some non-core processes and non-core parts to external units for processing and production, and the external processing expenses account for a low proportion of the current main cost. External processing price is mainly based on processing difficulty, processing cost and other factors, and is determined through price comparison and negotiation.

3. Sales model

(3) the industry situation

1. The development stage, basic characteristics and main technical threshold of the industry.

The company is a high-tech enterprise engaged in the design, research and development, production, sales and service of five-axis CNC machine tools and their key functional components, and high-end CNC systems. It is one of the few innovative enterprises in China that independently master high-end CNC systems and high-end CNC machine tools. According to the National Economic Industry Classification (GB/T4754-2017), the company’s industry is "C342 Metal Processing Machinery Manufacturing"; According to the Guiding Catalogue of Key Products and Services of Strategic Emerging Industries (revised in 2016), the company’s main products conform to "2.1 Intelligent Manufacturing Equipment Industry 2.1.4 Intelligent Processing Equipment" in the catalogue.

Five-axis CNC machine tool is a kind of machine tool with high technology content and high precision, which is specially used for machining complex curved surfaces. It has the advantages of wide application range, fine machining quality and high working efficiency, and is considered to be the most important machining tool for machining key components in aerospace, shipbuilding, precision instruments, power generation and other industries. According to the data released by QYResearch, the global five-axis CNC machine tool market sales will reach US$ 6.755 billion in 2020, and will increase year by year thereafter. It is estimated that it will reach US$ 13.835 billion in 2027, with a compound growth rate of about 10.79% from 2020 to 2027. In 2020, the domestic five-axis CNC machine tool market will be 665 million US dollars, accounting for 9.85% of the global market, and it is expected to reach 1.589 billion US dollars by 2027, when its share in the global market will reach 11.49%, with a compound growth rate of 13.25% from 2020 to 2027, which is higher than the global market.

The development of five-axis CNC machine tools needs strong precision machine tool design and manufacturing technology, and it can only be realized by close cooperation with cutting-edge CNC technology, so it is extremely difficult to develop and industrialize products. The development of five-axis CNC machine tools in China started late. At present, there are few domestic enterprises that can independently develop and produce, and the supply of domestic products is difficult to meet the domestic market demand. The domestic market is mainly occupied by multinational companies with hundreds of years of machine tool production experience in developed industrial countries such as Germany, Japan and the United States. However, in recent years, a number of five-axis CNC machine tool enterprises, including companies, have emerged in China, and their products have gradually been recognized by the market, gradually forming an import substitution trend.

2. Analysis of the industry position of the company and its changes.

The company is one of the few innovative enterprises in China with dual R&D systems for high-end CNC systems and high-end CNC machine tools. Through years of continuous R&D and innovation, it has formed the product layout of high-end CNC system products, high-end CNC machine tools and key functional components with independent intellectual property rights and core technologies. It can realize the R&D and manufacturing of various types of products in aviation, aerospace and other high-end equipment manufacturing, with independent and controllable core technologies and strong "import substitution" ability. The company’s main products are rich in specifications and comprehensive in layout, and have distinctive characteristics in the domestic high-end machine tool manufacturing field.

On the one hand, international advanced high-end machine tool enterprises, such as Haas, Otaru, Madzak, Fanuc, Demaji, and Fidia, have continuously extended their own technology chains and industrial chains, adopted personalized numerical control systems and some key functional components independently developed, and some enterprises have also sold them to the outside world. This business model not only ensures the safety and controllability of products, but also has higher market core competitiveness. The development model of the whole industrial chain, the whole talent chain and the whole technology chain established by the company can promote the continuous iterative improvement of the company’s own product technology and lay a solid foundation for the company’s products to benchmark international advanced products. At the same time, it can guarantee the technical safety of the company’s own products and the safety of the national high-end equipment industry, and make contributions to solving some "stuck neck" problems in the field of high-end equipment.

On the other hand, the localization rate of domestic high-end machine tools is less than 10%, and there is huge room for import substitution. However, the number of domestic enterprises engaged in high-end machine tools and their production and sales volume are still far from those of developed countries, and high-end CNC systems and key functional components are still mainly imported. With the rapid development of domestic high-end equipment, the demand for domestic CNC systems and key functional components is constantly increasing. The company can provide domestic enterprises with mature high-end CNC systems and key functional components, and at the same time meet all kinds of customization needs. The company can form strategic cooperation with domestic machine tool manufacturers, provide high-quality domestic CNC systems and key functional components solutions for domestic equipment, break foreign technology monopoly and promote innovation and promotion of domestic machine tool industry.

The company has presided over or undertaken 29 major national science and technology projects and 17 other national and local R&D projects. The company has participated in the formulation of 24 national standards and 10 industry and group standards. Authorized 93 domestic invention patents and 13 international invention patents. The five-axis CNC machine tools, high-grade CNC systems and key functional components independently developed by the company are the first sets in China, which have played a leading role in the breakthrough of CNC core technology in the field of high-end CNC machine tools in China and played a core role in realizing the strategic goal of "import substitution" of the company.

According to the data of China Machine Tool Industry Yearbook in 2021, there are 45 enterprises producing machining center products in the annual report of China machine tool industry in 2020, including Jinan No.2 Machine Tool, Shenyang Machine Tool, () and other large domestic state-owned enterprises and comparable listed companies (), Haitian Seiko, Guosheng Zhike, etc. The counted enterprises basically cover most domestic key and large machining center manufacturing enterprises in the industry.

From the perspective of the sales volume of the association statistics, the proportion of five-axis vertical machining centers sold by the company in 2020 is 13.62%; From the perspective of sales amount, the proportion of five-axis vertical machining centers sold by the company is 22.24%. No matter from the perspective of sales volume or sales amount, the market share of the five-axis vertical machining center sold by the company is at a high level.

3. The development of new technologies, (), new formats and new models during the reporting period and the future development trend.

According to Foresight Industry Research Institute’s Report on Market Demand Forecast and Investment Strategic Planning of CNC Machine Tool Industry in China, it is predicted that the market scale of CNC machine tools in China will grow steadily and rapidly in the future, reaching 572.8 billion yuan by 2024.

Forecast of China CNC Machine Tool Market Scale from 2019 to 2024

1) The promotion and popularization of new technology-five-axis linkage machining technology is the future development direction of the industry.

It is necessary to process complex curved surfaces in industry. Many key parts in ships, airplanes, rockets, satellites and spaceships have certain particularities and processing difficulties, which cannot be met by traditional processing methods. Only by using five-axis linkage, high-speed and high-precision CNC machine tools can the processing requirements be met.

With the trend of automobile lightweight, the traditional parts composed of multiple parts are integrated into a single part, and the processing characteristics of parts are changed from plane to space. At present, the major international suppliers of automobile parts processing equipment, including rabo, Madzak and Demaji, use a large number of five-axis machine tools to set up production lines.

2) New format-demand transformation from single machine tool that only completes a single process to flexible manufacturing unit that completes multiple processes.

Flexible manufacturing unit (FMU) is a manufacturing unit composed of single or multiple five-axis machining centers or compound machining centers and small automatic logistics devices to meet the requirements of efficient processing of multi-variety and small batch parts.

With the intensification of competition and rising costs of downstream production enterprises, especially the sharp rise of labor production costs and the increasingly frequent shortage of labor, more unmanned or less humanized manufacturing systems have begun to appear, and downstream customers’ demand for flexible manufacturing units that respond quickly to the processing market with multiple varieties and small batches will rise. Flexible manufacturing unit will appear as a complete set of equipment of "CNC machine tool+small logistics device (industrial robot, automatic pallet library, truss manipulator, etc.)", which will solve the pain point of the sharp rise of labor production cost in time and realize unmanned or less people.

3) New mode-from single product sales to intelligent manufacturing system integration scheme.

For a long time, most CNC machine tool enterprises in China only focus on producing machine tool products in a certain field, and do not have the ability to provide solutions for automated production lines. In recent years, downstream enterprises have put forward new demands for machine tool suppliers, and tend to cooperate with suppliers who have complete equipment production capacity, provide complete solutions or undertake more complex engineering general contracting projects and automation system transformation capabilities. Intelligent manufacturing system integrators with "turnkey" engineering capability of automated, flexible and intelligent production lines will be able to meet customers’ personalized, customized and differentiated production needs, thus improving customer stickiness. In addition, the encouragement of national and local policies for the construction of automated production lines in manufacturing industry will certainly promote the transformation of intelligent manufacturing equipment suppliers into intelligent manufacturing system integration solution providers.

(II) Events that have seriously affected the core competitiveness of the company during the reporting period, impact analysis and countermeasures.

Fourth, risk factors

(A) Not yet profitable risk

(2) Risk of sharp decline in performance or loss

(C) core competitiveness risks

At present, the company’s main business products continue to be developed in aerospace, automobile, machinery, mold and other fields, and the demand for the company’s products varies in different fields. If the company can’t quickly adapt to the process differentiation demand in different fields, quickly carry out technical iterative upgrading, enrich the varieties of five-axis CNC machine tools, provide differentiated five-axis CNC machine tools that meet the processing needs in different fields, and provide users with the best processing scheme, it will face adverse effects such as the products can’t adapt to the new market demand, resulting in slower revenue growth.

(4) Operational risks

1, the risk of increased competition

For a long time, the domestic market of five-axis CNC machine tools with the highest technology content is mainly occupied by multinational companies with hundreds of years of machine tool production experience in developed industrial countries such as Germany, Japan and the United States. Domestic independent production capacity is concentrated in the low-end market, and there are very few China enterprises that can independently develop five-axis CNC machine tools.

In recent years, due to the realistic demand of China’s aerospace engine, marine propeller, heavy generator rotor and other strategic equipment industries for high-end CNC machine tools, the state has continuously increased its support for the high-end CNC machine tool industry, and the technical level of China’s high-end CNC machine tool industry has been continuously improved. The performance and function of five-axis CNC machine tools produced by a few excellent domestic manufacturers can meet the needs of import substitution. The gradual rise of high-end CNC machine tool manufacturers in China may attract the attention of competitors and intensify competition. Coupled with the rapid growth of China’s high-end CNC machine tool market and the increasing awareness of the importance of import substitution, it will attract more potential entrants. Therefore, the company faces the risk of intensified market competition.

2. The risk that large foreign-funded enterprises still occupy the main market share in high-end segments.

Most of the large foreign-funded enterprises in the industry are large enterprises integrating upstream functional components and CNC system production, whole machine manufacturing and product sales. Based on the accumulation of industrial countries in architecture design, processing technology, industrial scale and talent echelon for hundreds of years, the reliability and accuracy of its high-end industrial products have obvious advantages over China’s emerging technology enterprises. Therefore, in the field of five-axis CNC machine tools, CNC systems and key functional components with high technical difficulty, downstream users in China still mainly choose foreign advanced products under the condition of free import, resulting in the products of large foreign-funded enterprises still occupying the main market share in the segmentation field.

3. Risks of upstream raw material procurement

The key functional parts of the company are mainly produced independently, and the external procurement is mainly standard parts, but the parts such as guide rails, lead screws and bearings are still mainly purchased externally. In the future, if the international trade friction intensifies, technical protection is strengthened or the demand of competitors increases, the parts such as guide rails, lead screws and bearings will face the risk of sharp price increase or prolonged supply cycle, which will adversely affect the company’s production and operation.

(V) Financial risks

1. Risk of fluctuation of gross profit margin

During the reporting period, the company’s main users were the aerospace industry, and its customization requirements for high-end CNC machine tools were higher in terms of processing accuracy and processing efficiency, and its gross profit margin was relatively high. With the gradual acceleration of the company’s marketization process, the company’s products are expanding into many fields such as precision molds, automobiles, clean energy and construction machinery. Due to the differences in customized configuration of high-end CNC machine tools used by different industries and users, the gross profit margin of related products will also be different, and the change of downstream customer structure may make the overall gross profit margin of the company fluctuate. Moreover, in order to meet the downstream market demand, industry competitors are also investing in or increasing the research and development and production of five-axis CNC machine tools. If the market competition intensifies in the future, the national policy is adjusted or the company fails to maintain the leading position in products, and the selling price of products and the purchasing price of raw materials are adversely changed, the company’s gross profit margin is also at risk of decline.

2. The risk of bad debts caused by the increase in the balance of accounts receivable.

The company has made provision for bad debts for accounts receivable according to the accounting standards. The company’s accounts receivable scale increases with the growth of operating income. If the economic situation worsens or customers have major operational difficulties, the company will face the risk of difficulties in collecting accounts receivable.

(VI) Industry risks

As an important part of intelligent equipment manufacturing industry, high-grade CNC machine tools are strategic industries for national economic and social development. The state has issued a series of encouragement policies to support and promote the development of China’s high-end CNC machine tools and basic equipment manufacturing industry, and enhance industrial innovation ability and international competitiveness. With China’s military modernization and the transformation and upgrading of manufacturing industry, the demand for independent control of core technologies is increasingly urgent, and the country’s industrial policy continues to increase. If the support of relevant national industrial policies is weakened in the future, it will have a negative impact on the company’s development.

(VII) Macro-environmental risks

The company’s downstream customers are mainly military enterprises that process aero-engines and missile engines, as well as civil manufacturing enterprises in the fields of precision molds, automobiles, clean energy, domestic commercial aircraft and construction machinery. The development of industries where downstream customers are located is highly correlated with the macroeconomic cycle. The adjustment of macroeconomic policies and its periodic fluctuations will have a great impact on the structural upgrading of downstream industries, as well as the operating conditions of end customers, capital turnover speed and fixed assets investment decisions, thus affecting the demand for high-end CNC machine tools.

If the macroeconomic growth rate continues to decline in the future and the downstream industries are depressed for a long time, it may exceed the company’s ability to cope through customer structure adjustment and internal tapping, which will have a great adverse impact on the company’s operation for a period of time.

(8) Risks related to depositary receipts

(9) Other major risks.

V. Discussion and analysis of the company’s future development

(A) the industry pattern and trends

1. For a long time, domestic CNC machine tools have been in a situation of "low-end civil war, mid-end competition and high-end failure", and the high-end market has been occupied by foreign brands.

Developed countries and regions have a long history in the industry of advanced manufacturing equipment such as high-end CNC machine tools, and related enterprises have accumulated advantages in technology, brand and capital, and have the first-Mover advantage, occupying the high-end market. The domestic market of five-axis CNC machine tools with the highest technology content is mainly occupied by multinational companies with hundreds of years of machine tool production experience in developed industrial countries such as Germany, Japan and the United States. The domestic independent production capacity is concentrated in the low-end market, and there are very few China enterprises that can independently develop five-axis CNC machine tools. According to the Outline of the Development of Machinery Industry in the 14th Five-Year Plan, at present, the self-sufficiency rate of high-end CNC machine tools in China is less than 10%, which basically depends on imports. Therefore, the main competitors of China’s five-axis CNC machine tool enterprises represented by the company are mainly international manufacturers.

2. China is a big machine tool consumer, attracting a large number of international brand CNC machine tool enterprises to stay in the China market.

China has become the most important machine tool consumption market in the world. According to the data of German Machine Tool Manufacturers Association (VDW), the consumption of machine tools in Chinese mainland in 2021 was 23.6 billion euros, up 27% year-on-year, accounting for about 34% of the global market. However, on the whole, China’s machine tool industry presents the development characteristics of "big but not strong", and the field of high-end CNC machine tools is still a weak link with strong import dependence.

According to the data of cmtba, in 2022, the import volume of metal processing machine tools in China reached US$ 6.6 billion, of which the total amount of imported machining centers was US$ 2.37 billion. The average price of imported machining centers increased significantly year-on-year, the proportion of imported high-end machining centers increased, and there was huge room for domestic substitution.

In April 2022, Nippon Denso (which owns Mitsubishi Heavy Industries, OKK and other machine tool enterprises) expanded its factory area in Pinghu, Zhejiang Province from the original planned 60,000 square meters to 200,000 square meters to produce gear processing machine tools. At the same time, Demajisen Seiki invested 100 million US dollars to build Pinghu factory, with an estimated annual output of 2,200 machining centers. In the same year, Demajisen Seiki opened Tianjin Green Factory and Shanghai Medical Device Technology Center. In June, 2022, German Wheeler Xile Machine Tool (Qingdao) Company laid the foundation stone for the new Jimo factory covering an area of 73,000 square meters, and it is estimated that it will achieve the production of 300 five-axis and horizontal processing machine tools. In July 2022, the foundation stone was laid for the second phase factory of German (SW) Esway Machine Tool Co., Ltd., and China will become the largest overseas R&D and manufacturing base in the world, with an annual production capacity of about 350 machining centers. Thus, the continuous investment of foreign-funded enterprises in China market shows the high prosperity and development space of domestic five-axis machine tool industry.

3. China machine tool industry is transforming into a high-end field.

Five-axis CNC technology is one of the important standards to measure the manufacturing ability and technical level of complex precision parts in a country. Five-axis CNC machine tool is the only means to solve the cutting of key industrial products such as aerospace and aero-engine impeller, impeller, blade and marine propeller. From the Batumi List after World War II to the Wassenaar Agreement after the Cold War, the developed countries in the west have always adopted the five-axis CNC system and five-axis CNC machine tools as strategic materials to implement the export license system, and imposed strict technical blockade and export restrictions on many countries, including China.

After decades of development, the domestic CNC machine tool industry has been developing independently and drawing on foreign experience. From scratch, it has grown continuously, resulting in such established enterprises as Shenyang Machine Tool (000410.SZ) and Qinchuan Machine Tool (000837.SZ), which are in the forefront of the world, as well as a number of core design technologies and manufacturing processes such as Kede CNC, which can provide high performance for their own dedicated application fields and product types.

In recent years, with the help of favorable market conditions such as the transformation of China’s manufacturing industry, the rising demand for high-end CNC machine tools, and the huge import substitution space, such emerging manufacturers have made great efforts to develop their own products and technical level, enhanced their financial strength through public financing and other means, achieved remarkable development, and rapidly increased their market share.

4. The rapid development of high-end manufacturing industry has brought new development opportunities for domestic high-end machine tools.

At present, China is in an important stage of transformation from a manufacturing power to a manufacturing power. The intelligent manufacturing equipment industry is the basic guarantee for the adjustment and upgrading of the entire economic structure and the leading industry for the transformation and upgrading of the national economy. In the new round of industrial upgrading, high-end manufacturing industry will gradually replace simple manufacturing industry, and manufacturing industry will gradually change from labor-intensive industry to technology-intensive industry. This transformation and upgrading will also promote the technological upgrading of the intelligent manufacturing equipment industry, which will greatly increase the market demand of middle and high-end CNC machine tools. High-end CNC machine tools are mainly used in aviation, aerospace, nuclear, electronics, ships, weapons, energy, automobiles, molds, knives and other key industries, especially aviation, aerospace and military industries. The demand for localization is urgent, the stock needs to be updated urgently, and the market growth is expected.

Taking the aviation industry as an example, high-end CNC machine tools mainly serve the processing of key parts of military aircraft and civil aircraft. In the civil aircraft market, Comac China has launched three classes of passenger aircraft, namely ARJ21, C919 and CR929. On December 9, 2022, Comac China delivered the world’s first C919 large passenger plane to China Eastern Airlines, marking a new milestone in the development of large aircraft. According to the "2022 Shanghai Science and Technology Progress Report" issued by the Shanghai, China Municipal Science and Technology Commission, "by the end of 2022, the C919 large passenger aircraft had received 1,035 orders from 32 customers; In December 2022, the ARJ21 new regional aircraft was delivered to the first overseas customer, Indonesian Lingya Airlines. ARJ21 received 690 orders from 25 customers and delivered a total of 100 aircraft to 9 domestic and foreign customers. " According to the Market Forecast Annual Report of Comac China (2022-2041) issued by Comac China, with the steady rise of China’s economy, China’s civil aviation industry will enter a period of development quality improvement and pattern expansion. By 2041, the fleet size of China will reach 10,007, accounting for 21.1% of the global passenger aircraft fleet. China aviation market will become the largest single aviation market in the world.

According to the report on the draft government budget released by the National People’s Congress on March 5, 2023, China’s military budget in 2023 was 1,553.7 billion yuan, up 7.2% year-on-year, and the increase rate was 0.1 percentage point higher than that in 2022. It was also the third consecutive year since 2021 that China’s military budget rose slightly, and the situation of strengthening the army was urgent. At present, the international environment is deteriorating, regional conflicts and confrontation between great powers are escalating, and it is reasonable and urgent to speed up national defense investment. China’s military industry is still in the stage of compensatory development. The aerospace and military industries, represented by missiles, rockets and satellites, have entered the stage of rapid expansion of production, and high-end CNC machine tools have played a strong support and guarantee role in aviation, aerospace and military industries.

In addition to the urgent demand for five-axis CNC machine tools in key industries such as aviation, aerospace and military industry, with the transformation of automobile to lightweight and integration, "one-piece die casting" forms a variety of special-shaped components, which provides more opportunities for five-axis CNC machine tools in finishing. The processing of battery, motor housing, reducer housing, bogie, front and rear axle and other parts of new energy vehicles has become a new growth point of five-axis machine tools. According to the latest data from China Association of Automobile Manufacturers, in 2022, the production and sales of new energy vehicles reached 7.058 million and 6.887 million respectively, up by 96.9% and 93.4% year-on-year, and the market share reached 25.6%. With the continuous expansion of the new energy automobile industry, the integrated processing equipment and automatic production line of automobile parts will usher in more development opportunities. At the same time, due to insufficient overseas supply and greatly enhanced export competitiveness of China automobile enterprises, automobile exports exceeded 3 million vehicles in 2022, up 54.4% year-on-year, effectively boosting the overall growth of the industry.

Tool is a tool used for cutting in mechanical manufacturing, and it is the basic industry in mechanical manufacturing and major technical fields, accounting for about 90% of the whole mechanical processing workload, which directly determines the production level of mechanical manufacturing. According to the data of cmtba, China Customs and Forward-looking Industry Research Institute, in 2022, the tool export value was 23.187 billion yuan, up 2.98% year-on-year; The import value of cutting tools was 9.732 billion yuan, down 8.47% year-on-year. The export value is obviously greater than the import value, and the dependence on imports continues to decline. The continuous increase of China’s tool export shows that domestic tool products occupy an important position in the world tool market. China needs to import more than 1,000 five-axis tool grinders every year, and the company’s five-axis tool grinding center is one of the few equipment in China that can grind complex tools such as ball end mill and corrugated knives, and has a good market prospect.

5. Support of national industrial policies

As an important part of equipment manufacturing industry, CNC machine tools have become one of the important material bases of national industrial modernization. Our government has always attached great importance to the development of CNC machine tool industry and its sub-sectors, and has successively issued a series of relevant policies to guide industry participants to increase R&D investment, strengthen innovation awareness, break through technical bottlenecks, improve the effective supply of common technologies and high-end products, and meet the market demand in downstream areas.

On May 8, 2015, the State Council officially issued "Made in China 2025", which became the action program for guiding the adjustment of industrial structure and upgrading of manufacturing industry, and then implementing the strategy of building a strong country. High-end equipment is the foundation of manufacturing transformation. In order to promote the transformation and upgrading of manufacturing industry, the Chinese government has vigorously promoted the development of high-end equipment industry and issued a series of industrial policies. In 2018, the Bureau of Statistics issued the Classification of Strategic Emerging Industries (2018), which listed metal cutting machine tools, metal forming machine tools, machine tool control systems, machine tool functional parts and accessories as "intelligent manufacturing equipment industry" in the "high-end equipment manufacturing industry". In November 2019, thirteen ministries and commissions, including the Ministry of Industry and Information Technology and the National Development and Reform Commission, jointly issued the "Special Action Plan for Improving the Design Capability of Manufacturing Industry (2019-2022)", clearly pointing out that in the field of high-end CNC machine tools, it is necessary to achieve a breakthrough in original design, strengthen the key design of high-end equipment manufacturing industry, and focus on breaking through the system development platform and servo mechanism design. In March, 2021, the Fourth Session of the 13th National People’s Congress voted to pass the 14th Five-Year Plan for National Economic and Social Development in People’s Republic of China (PRC) and the Outline of Long-term Goals in 2035. The Outline emphasizes promoting the optimization and upgrading of manufacturing industry, deeply implementing intelligent manufacturing and green manufacturing projects, developing a new service-oriented manufacturing model, promoting the high-end intelligent greening of manufacturing industry, cultivating advanced manufacturing clusters, and promoting the innovative development of high-end CNC machine tools and other industries.

Therefore, the new round of industrial structure adjustment and upgrading is bound to replace the traditional manufacturing industry with advanced manufacturing industry. This transformation and upgrading will greatly increase the update demand of high-performance CNC machine tools as one of the industrial mother machines. The State Council’s Opinions of the State Council on Accelerating the Revitalization of Equipment Manufacturing Industry, High-grade CNC Machine Tools and Basic Manufacturing Equipment, and China Machinery Industry Federation’s Outline for the Development of Machinery Industry in the Tenth Five-Year Plan all provide strong policy support for the development of high-grade CNC machine tool industry represented by five-axis CNC machine tools.

　　The ancient city is a mirror to show history and a window to review the glorious past.

　　This year marks the 40th anniversary of the State Council’s announcement of the first batch of national historical and cultural cities. Since the list was published on February 8, 1982, the number of national historical and cultural cities has expanded from 24 at the beginning to 140.

　　Many of these famous historical and cultural cities are born and prospered with the Grand Canal in China. In Jiangsu alone, there are eight national historical and cultural cities located on the banks of the Canal, ranking first in the country.

　　Let’s have a look!

　　Suzhou

　　Small bridges and flowing water, pink bricks and tiles, beautiful mountains and rivers and elegant gardens. Suzhou, an ancient city with a long history, still maintains a double chessboard pattern of "land and water are parallel and rivers and streets are adjacent" and is one of the first national historical and cultural cities.

Shantang Street

　　Accumulate gold and jade, gentle and rich country. In the history of Suzhou, the traffic was busy, and hundreds of people were fighting for the flow. The wealthy businessman dajia and the literati gathered here. Gardening flourished and culture flourished, and Kunqu Opera and Su Ju were born here.

　　There are countless scenic spots on the odd river. Xushuguan town, "Jiangnan is going to rush to the ground, Wuzhong Living Wharf"; Shantang Street, "the most prosperous and romantic place in the world of mortals"; Fengqiao Scenic Area is famous all over the world because of the phrase "Hanshan Temple outside Gusu City, the bell rings at midnight to the passenger ship"; Gu Xiang in Pingjiang has been well preserved so far, which can be called the epitome of Suzhou ancient city … …

Fengqiao scenic spot

　　Yangzhou

　　Yangzhou, located at the intersection of the Yangtze River and the Beijing-Hangzhou Grand Canal, has the reputation of "a famous place in the left of Huai River and a beautiful place in the west of Zhu River". The history of building a city can be traced back to 486 BC, and it has been more than 2,500 years since Fu Cha, the king of Wu, opened the ditch and built the city of Han. It is one of the first national historical and cultural cities.

Yangzhou ancient canal

　　Nowadays, Yangzhou, on the side of the Grand Canal, maintains a relatively complete ancient city pattern and street texture. By the canal, scenic spots such as Slender West Lake and Geyuan attract a large number of tourists every year, and the canal water has also spawned a wonderful collection of Yangzhou culture, including Yangzhou Quyi, woodblock printing and Huaiyang cuisine … …

　　Zhenjiang

　　Zhenjiang was selected as the second batch of national historical and cultural cities. This is the only junction between the Yangtze River and the Beijing-Hangzhou Grand Canal. Relying on the risks of the Yangtze River and the benefits of the Grand Canal, Zhenjiang has produced water transport culture, ferry culture and military culture that affect the whole country.

　　Xijindu, Xinhe Street and Jingkou Gate … … In Zhenjiang, the scenery of the ancient canal is changing with each passing day. Looking at the present, the green and livable canal business card has become a distinctive symbol of Zhenjiang.

　　Wuxi

　　Known as Cloth Wharf, Money Wharf, Silk Capital and Rice Market, Wuxi has been a land of plenty since ancient times. This is the birthplace of ancient Wu culture, modern national industry and commerce and modern township enterprises. In 2007, Wuxi was added as a national historical and cultural city.

Qingming bridge

　　To understand the history of Wuxi, we can’t bypass the Grand Canal which flows around the city. Nanchang Street is centered along the ancient canal, with all kinds of ancient buildings, all kinds of delicious food and handicrafts, which perfectly presents the alley-style old street in the south of the Yangtze River.

Qingming bridge

　　Take a boat and drive slowly under the Qingming Bridge, like painting a landscape and feeling the folk customs of a hundred years ago. In Huishan ancient town, listening to a song "Two Springs Reflecting the Moon" and tasting the leisure morning tea of the Canal is very pleasant.

Huishan old town

　　Changzhou

　　"The country with three Wu Jin belts is a meeting of hundreds of boats and cars." Changzhou, Longcheng, is an important birthplace of Wu culture and Qi-Liang culture. It is known as "the name of China and Wu, and the name of eight cities". In 2015, Changzhou was added as a national historical and cultural city.

　　According to historical records, Changzhou has become an important post station for water transportation since Sui Dynasty. After three times of southward migration, it has formed the "three rivers and four cities" style of "building a city by the river, the river moving with the city and the river matching the city".

Changzhou section of Grand Canal

　　During the Millennium, the boats that traveled from south to north gave birth to Changzhou’s magnificent canal culture. Qingguo Lane, Tianning Temple, Dongpo Park … … A grand canal, smart Changzhou, also accumulated Changzhou.

　　Gaoyou

　　Gaoyou is a county-level city managed by Yangzhou City, Jiangsu Province, and its strength cannot be underestimated. It is a world heritage city, a national historical and cultural city, a national civilized city and a national tourism demonstration area. It is also the hometown of China folk songs, China Qixi culture, Chinese poetry, national philately and China architecture. In 2016, Gaoyou was added as a national historical and cultural city.

Jiangsu Li Canal-Gaoyou Irrigation District

　　Gaoyou’s ancient canal passes through the city, with tributaries all over the city, and many beaches are distributed, which is a veritable city that thrives on water.

　　Bright green vegetables and glossy peppers … … In the early morning of summer, alpine vegetables from Longnan Township, Longquan City, with dew, entered the cold chain for preservation and reached more than 20 vegetable counters in Hangzhou Hualian Supermarket. Under the brand logo of "Lishui Mountain Farming", these alpine vegetables are very popular.

　　In the past, there were many kinds of agricultural products in mountainous cities, and many subjects were small, so it was difficult for all kinds of agricultural brands to form influence and competitiveness in the market. Four years ago, Lishui integrated well-known agricultural products such as Jingning Huiming Tea, Qingyuan Mushroom, Suichang Jumi and Chuzhou Bailian, and created the first regional public brand in China — — "Lishui Mountain Farming".

　　From "small-scale" selling native mountain products to "Lishui Mountain Farming" regional brand, Lishui people look for the "golden key" of the integration of agriculture and tourism. Agricultural products nurtured by good mountains, good water and good air collectively put on the regional brand coat of "Lishui Mountain Farming", which shows the true connotation of "ecological fine agriculture".

　　Create a big agricultural brand

　　At 4 o’clock on the afternoon of the 15th, the commodity experience store in Lishui Garden Town "Lishui Shangeng" tourist destination, although it was almost the end of work, there were still tourists shopping. These agricultural products with unified signs became the best accompanying gifts for traveling to Lishui.

　　“‘ Lishui Shangeng ’ How did you come up with this beautiful idea? " Liu Zhilong, deputy general manager of Lishui Agricultural Investment Development Co., Ltd., participated in the creation of the brand "Lishui Mountain Farming" all the time. Facing the reporters’ unanimous questions, he thoughtfully said, "This is not an idea, it is forced! Lishui wants to develop, there is no other way to go, and the combination of fine agriculture and agricultural tourism requires a large brand integration resource. "

　　"Mountain" is the biggest natural feature of Lishui, and "farming" is the embodiment of the traditional mode of production. Lishui is divided into nine mountains, half water and half fields. Under the environment of "good mountains, good water and good air", the agricultural products cultivated by traditional ecological production methods must be "ecological products" and "healthy products". However, agricultural enterprises are "low and scattered", and although agricultural products are excellent, they cannot sell at high prices.

　　Li Genyuan, the head of Hulugang Ecological Breeding Professional Cooperative in Suichang, said that she also had her own brand in the past. "But at that time, it was a brand, but it was actually a name. Customers often had doubts before buying, and they were afraid that it was not an authentic earth egg."

　　Like Li Genyuan, many leaders of agricultural products cooperatives in Lishui have encountered this problem: without brands, customers don’t trust products.

　　"From the hard work in the field to the simple wishes of the villagers, people all feel the importance of creating a big brand of agricultural products for Lishui people." Liu Zhilong clearly remembers that experts from Zhejiang University had expressed such feelings after being invited to visit Lishui.

　　In 2013, Lishui City established a state-owned agricultural investment company to implement ecological planning, standardized production, brand management and e-commerce marketing for fine agriculture. The following year, Lishui entrusted CARD China Agricultural Brand Research Center of Zhejiang University to carry out brand strategic planning, and in September, Lishui Shangeng was founded as a public brand.

　　Liu Zhilong explained that "Lishui Shangeng" was registered by Lishui Eco-agriculture Association and entrusted to the state-owned company Lishui Agricultural Investment and Development Co., Ltd. to operate, which ensured that "Lishui Shangeng" not only had the credibility of government endorsement, but also had the flexibility of market participants.

　　Walking in Lishui, you will find that no matter the scenic spots, homestay farmhouses, high-speed railway station, bus stations and high-speed service areas, there are commodity shopping outlets in tourist destinations with uniform styles, where Lishui’s agricultural special products are neatly placed, and the unified "Lishui Shangeng" logo is printed on the product packaging box.

　　The original price of a Jinyun duck in 60 yuan is now 118 yuan, and the organic tea in Meixianshan, liandu is sold at a good price of 1880 yuan per catty & HELIP; … Chen Xiaofang, chairman of Lishui Baiwei Agricultural Products Professional Cooperative, told the reporter that through the refining and excavation of the brand value of Lishui ecological agricultural products, and then through exhibition communication and experience communication, the "Lishui Shangeng" brand has blown up an ecological whirlwind in Shanghai, Hangzhou and Ningbo. For this reason, after Chen Xiaofang’s products such as "three-year-old ginger" and "ecological lotus seeds" were added to the "Lishui Shangeng" brand, the demand was in short supply, and the price also rose several times.

　　An upgraded version of "Lishui Mountain Farming" ecological agricultural products began to emerge in all parts of Lishui. Since last year, Jingning has adhered to the concept of Lucid waters and lush mountains are invaluable assets, tried every means to turn ecological advantages into income-increasing advantages, and guided farmers to develop eco-fine agriculture by taking advantage of the characteristics of abundant sunshine, large temperature difference between day and night and few pests and diseases in mountainous areas above 600 meters above sea level, so as to achieve high quality and good price. Like a village inhabited by She people — — Sange village, because of the development of alpine vegetables, has increased its per capita income by more than 3000 yuan since last year.

　　In the past four years, the effect of "Lishui Shangeng" brand rich farmers has initially appeared. According to the data, by the end of June 2018, there were 733 members of Lishui Ecological Agriculture Association, and 1,122 cooperative bases were established. The brand sales totaled 10.158 billion yuan, with an average premium of over 30%.

　　With the development of "Lishui Mountain Farming" brand, the products of enterprises are moving from the original one to a hundred flowers. Many enterprises have improved their efficiency through the unified management of the brand "Lishui Shangeng", especially the business model of "direct supply from base, inspection access and full traceability".

　　The combination of agriculture and tourism has feelings

　　If traditional agriculture pays attention to the "planting" and "selling" of agricultural products, then in Lishui, the word "agriculture" is given more feelings.

　　"This is just a window for tourists to experience. To feel the real fine agriculture, there are still many places to experience in Lishui!" Wu Huabo, chairman of the commodity experience center of Lishui Garden Town "Lishui Shangeng" tourist destination commodity experience store, shouted at dozens of reporters present.

　　The Baixing mushroom industry mentioned by Wu Huabo is also in the interview point of our trip. Baixing Mushroom Industry, located in Bihu Town, liandu, invested more than 20 million yuan in the renovation a few years ago, and spent 3 million yuan on the design fee alone. Now, you can go sightseeing, pick, DIY, taste mushroom food, and then buy processed products when you leave. It is named "Mushroom Magic Mushroom Forest" here. If edible fungi only sell raw materials, the added value is very low, but after the integration of agriculture and tourism, it is completely different.

　　Nowadays, in Lishui, there are more and more points like Baixing Mushroom Industry. Lishui is planning to link dots into lines and launch a series of personalized agricultural sightseeing routes, so that tourists can enjoy both sightseeing and shopping.

　　"In the past, our agricultural development company pushed ‘ Lishui Shangeng ’ It may be more from the perspective of modern agricultural development. Now, the brand has become the focus and core of the work of Lishui Municipal Party Committee and Municipal Government, and it has been placed in ‘ Global tourism ’ Even the economic and social development of Lishui is highly promoted. "

　　Wang Jingquan said with emotion, now everyone is focusing on how to transform agricultural products into tourist commodities, taking "Lishui Mountain Farming" as the main starting point and platform, and starting to take the initiative to dock at home. The whole supply chain system will immediately become strong, and the main body joining "Lishui Mountain Farming" will grow rapidly.

　　Reporter Chen Jiaying

　　It’s as beautiful as water in a mirror and as beautiful as a mountain. Although it’s naturally beautiful, it’s still cultivated … … "Lishui Mountain Farming" is the first big brand in China to integrate global agricultural resources at the prefecture-level city level.

　　"Nine mountains, half water and half fields", mountain is the biggest natural feature of Lishui, and mountain farming is the most important production form of Lishui farming. The legend of Jinyun sesame seed cake originated in the period of Xuanyuan Huangdi. More than 1,000 years ago, Huiming and Shangjian Temple planted tea, and more than 800 years ago, Wu San publicized the source of mushrooms in the world … … Therefore, "Lishui Mountain Farming" shows the historical origin of Lishui farming civilization.

　　It is this "jiusan" that has created the original ecological environment with clear water source, fresh air and safe soil quality in Lishui, bred rich products such as Jingning Huiming Tea, Qingyuan Mushroom, Suichang Jumi and Chuzhou Bailian, and created the core competitiveness of Lishui ecological fine agricultural products. "Lishui Mountain Farming" presents Lishui’s green and high-quality fine agriculture.

　　In recent years, food safety problems occur frequently, the pace of urban life is accelerating, and consumers are increasingly pursuing pollution-free and original ecological agricultural products. This phenomenon reflects the yearning for a safe and natural life in the traditional farming era and the desire to return to simplicity and simplicity. "Lishui Mountain Farming" is a response to the realistic demand of consumption upgrading and green consumption.

　　From the perspective of regional overall planning, with the city’s agricultural brands, local agricultural enterprises have endorsed and can thrive under the mode of "hen with chicken"; For Lishui as a whole, this way to make all kinds of brand resources into a fist, promote the branding, standardization, e-commerce and financialization of agricultural products in a unified way, and help farmers improve their bargaining power is obviously the best way to promote green development and accelerate rural revitalization.

　　Liandu builds a homestay complex with the model of "ancient village+ancient creation"

　　"Resurrection" of Hollow Village

　　Trainee reporter Wang Shiqi reporter Liu Leping

　　Qingshan, Lvshui and Ouyue Diaojiaolou, the ancient residential group of Xia Nanshan Village, is located in Xia Nanshan Village, Bihu Town, liandu. It was built in the Wanli period of the Ming Dynasty and is the residence of the Zheng family. At 6 o’clock on the afternoon of the 15th, the reporter of the "Great River Running" interview group arrived in Xia ‘nan Village, bathed in the afterglow of the sunset, and it was peaceful and peaceful. Some reporters exclaimed: "It’s really a paradise!"

　　Strolling through the ancient village and stepping up the stairs, the reporter saw a cafe with simple and fashionable furnishings and unique vicissitudes of the ancient house, which had a unique flavor. "The old house in the past has become like this, and I never dreamed of it." When I asked, it turned out that this was the ancestral home of Wu Jucheng, a villager in Xia Nanshan, sitting in a brand-new house. He told reporters about the story of Xia Nanshan Village in recent years.

　　Xia Nanshan village is divided into new village and old village, which are built beside the mountain and scattered, and are listed as provincial and municipal cultural protection units. "Mountain roads are not easy to walk, and mountains and rivers often destroy farmhouses." Lao Wu told reporters that this cafe used to be his old house. In the past, it was a broken wall.

　　The environment in the village is poor, and young people also go out to work, and there are fewer and fewer people in the village. In 2005, the government organized villagers to move down the mountain to build houses, and Xia Nanshan Village became a hollow village. People went down the mountain, but the knot in their hearts was not untied. "We grew up in the village, and the village is also our home." Lao Wu said that after moving down the mountain, he would visit the village every year. Seeing, the old houses on the mountain are getting more and more dilapidated, and most of them soon collapsed when no one lived.

　　The connecting flight happened two years ago. In 2016, the local government and enterprises joined forces to introduce industrial and commercial capital, and through "protection+development+utilization", the B&B complex was built in the mode of "ancient village+ancient creation", giving the ancient village new vitality while protecting it. Lianzhong Group took a fancy to these old houses and immediately signed a 30-year contract with the village. It plans to invest 60 million yuan to transform the old village into a personalized hotel.

　　Lianzhong Group rents the right to use the house from the villagers through the village collective. According to the construction area, the rent will increase once every five years. All other investments and operations are undertaken by Lianzhong Group. In order to support the restoration and transformation of ancient villages, the government invested in the construction of infrastructure, improved water and electricity, and paved the way. Today, this once hollow village has been "resurrected".

　　You can see the mountains, you can see the water, remember to stay homesick. The restoration plan of the ancient village cheered Lao Wu up. Nowadays, under the exterior of the old house, there is a five-star interior, and Lao Wu’s old house has turned into a beautifully decorated cafe. The project development is still going on. Yu Xuebing, chairman of Lianzhong Group, said that it plans to build more than 20 formats and more than 100 rooms in the future.

　　Xia Nan Shan has become a "online celebrity" homestay village, attracting a large number of tourists and makers to settle in, and it has also become a "hematopoietic pump" for rural revitalization. "Every year, I have three incomes, the rent of the house, the salary of being a gardener here and the income of planting bayberry. Life is getting more and more hopeful." Lao Wu said with a smile. The once hollow village has been rejuvenated by the restoration and development of ancient villages. Xia Nanshan Village has gathered a large number of young people who have returned to their hometowns to start businesses. At present, more than 460 people have returned to work in the village.

　　Reporter Chen Jiaying

　　On the afternoon of August 15th, Lishui was in the hot sun. The "Great River Flowing" interview group drove to the painting town of Lishui Guyan. "How beautiful!" Songyin Creek gurgled under the bridge, and a thousand-year-old tree was planted beside the road, walking on the Tongji ancient road, and reporters at the scene took photos one after another.

　　This is the location of the weir head in Tongji Weir more than 1,500 years ago, and it is also the source of vitality for irrigating more than 30,000 mu of fertile land in Bihu Plain. "More than a decade ago, there were potholes and illegal construction in the past. After environmental improvement, the water was clean and the environment was beautiful. Farmhouses and homestays rose for the second time and became the main source of villagers’ income." Lei Jianhua, deputy director of Guyan Painting Township Management Committee, said.

　　To get from the "ancient weir" to the "hometown of painting", you need to cross the river by boat. I saw reeds swaying on both sides of the river, sails occasionally appearing, and wild interest was born. "Now we are driving on the Oujiang River. At present, the water quality of 92.8% section of Guyan Huaxiang Town keeps the national Grade II water standard all the year round. The scenic spot has the most complete preserved ecological river landscape in Zhejiang Province, and the natural resources such as beaches, islands, islands and forests on both sides of the river set off with the human resources such as weirs, harbors, dams and villages, making it the birthplace of barbizon oil paintings in Lishui and ‘ The hometown of photography in China ’ The main creative base. " Lei Jianhua said.

　　While speaking, Dagang Tou Town, where the "hometown of painting" is located, arrived.

　　As soon as we landed, everyone was attracted by the scenery on the shore. Two young art students are sketching and painting on the shore, and several girls wearing Hanfu are showing tea art … … As soon as I arrived at the "hometown of painting", the literary atmosphere came to my face.

　　"A small town cultural festival is being held here." Following the direction of Lei Jianhua’s finger, the reporter saw a huge painting made up of hundreds of oil paintings. Lei Jianhua said that during the Cultural Festival, they mobilized more than 100 local artists, art lovers, tourists, students and other people from Lishui to create together, and merged into a landscape mosaic painting with great visual shock. "In the past few days, we have also held oil painting exhibitions, music festivals, creative markets and other activities to enrich the connotation of the town cultural festival."

　　It is under the call of this beautiful mountain, water and artistic atmosphere that more and more tourists visit the ancient weir painting town, which drives the continuous development of tourism in the town. Many small town residents also seized the opportunity to open farmhouses and homestays in the old streets.

　　Walking in the small town, the reporter met the proprietress Xie Dajie of Xiangshui Bridge. "In the past, we only knew to work in other places. In 2005, the local government called on us to engage in farmhouse music and took us to visit and study in Wuyi and other places. Three years ago, the village mobilized us to upgrade the farmhouse to a homestay. Yes, we redecorated 12 rooms, and tourists came to eat well and live well. " Sister Xie told reporters that she and her husband and daughter run farmhouses and homestays together, and the annual income can reach 700,000 to 800,000 yuan.

　　According to reports, the per capita income of residents in the core area of Guyan Huaxiang Town has increased from more than 3,000 yuan in 2005 to 35,000 yuan today, an increase of 10 times; The economic income of leisure formats such as farmhouses and homestays in towns and surrounding areas increased from 1.9 million yuan in 2010 to 72 million yuan, an increase of 38 times.
