Compared with motorbikes, motorcycle is the first choice to consider its own needs. For most users, it is undoubtedly the best choice to choose a rickshaw. As a rickshaw in the world, large displacement accounts for the minority and small displacement accounts for the majority. If you pursue economy, you should first choose an entry-level rickshaw with small displacement. With reference to its entry-level cost performance, you can consider 125 cc-190 cc, and this luxury DL150 can also do all the long-distance work.

The advantage of DL150 is that its displacement is relatively small, and its comprehensive fuel consumption per 100 kilometers is more fuel-efficient than that of 250cc and above. If it is used for long-distance motorcycle travel, DL150 can save more fuel consumption, and the cost maintenance of small-displacement motorcycles is more economical, which is the best choice for pursuing cost performance and practicality.

On the other hand, this Hauser DL150 is still the most popular entry-level trolley at present. First of all, as a 150cc-class trolley, DL150 has excellent quality and reliable performance. If it is not interested in power performance, DL150 can also be used as the main long-distance motorcycle vehicle.

In terms of configuration, the DL150 is a single-cylinder air-cooled engine. With a small displacement, it may achieve more ideal efficiency, and the fuel consumption is low, so it is very cost-effective to travel long distances. Coupled with the quality of Haojue’s workmanship, this small trolley is also an entry-level choice with smaller displacement compared with DL250. It not only has the advantages of small displacement vehicles, but also has the blessing of big brands in configuration, with high-end configurations such as KYB shock absorption and ABS.

In terms of price performance, this DL150 is also a cost-effective choice in the 10,000-yuan level. The official guide price is only 14,680 yuan. For the price of nearly 15,000 yuan, it is quite cost-effective. Considering the small displacement of the DL150, it is also a wide choice of people. Both novices and veterans have different views on small-displacement pull cars. Choosing a small displacement at the entry level can improve your driving skills. At the same time, for the entry-level rally car, DL150 also has excellent quality. As a big brand with domestic roads open to traffic, Haojue is not stingy in configuration. With the blessing of major brand accessories, it is more reassuring to choose a long-distance motorcycle tour.

There is also the production background of Haojue DL150, which was launched only a few years after the DL250 went on the market. Therefore, it is also an entry-level rally car that was developed after careful consideration, and it meets the best choice for DL series rally cars with smaller displacement.

Is it a brand? Corvette is a Chevrolet brand. To be precise: Corvette is a sub-brand of Chevrolet, because Corvette is an independent super-running brand, so it is only Chevrolet.

Chevrolet is the United States, and of course Corvette is also the top super brand of GM.

Corvee, named Corvee in English, is a super sports car owned by Chevrolet. Corvette can be regarded as an American national treasure super sports car.

Corvette’s name followed the name of 17(||) British ships, which was intended to challenge the popular British sports cars at that time.

Corvette was born in 1953. The first generation of corvette was called. The second generation Corvette is called; The third generation of Corvette is called, from which the conclusion is drawn.

On July 18, 2019, the eighth generation of Corvette will be launched in the world. Corvette C8 adopts a brand-new black LOGO, and adopts a mid-engine design for the first time.

In terms of power, (||)C8 is equipped with a 6.2-liter V8 engine code-named LT2, matched with an 8-speed powershift, with a maximum horsepower of 502Ps and a maximum torque of 637 N m. According to the official news, Corvette C80-96km/h accelerated in less than 3 seconds.

Moderator: Hello, netizens, and welcome to the series of interviews with famous Fujian medical scholars. In order to implement the spirit of "Several Measures to Promote the Inheritance, Innovation and Development of Traditional Chinese Medicine in Fujian Province", excavate and inherit the academic essence of Fujian Medical School, promote the prosperity and development of Fujian Medical School, widely spread the touching stories of inheritors of various schools, and give full play to the advantages of traditional Chinese medicine to serve the masses, the Fujian Provincial Health and Wellness Committee launched a series of interview programs on the video recording project of Fujian Medical School-"Famous People of Fujian Medical School". Today, the guest of "Famous People of Fujian Medical School" is the third affiliated to Fujian University of Traditional Chinese Medicine.

[Guest Profile]-

Chen Boyi, director of the Department of Traditional Chinese Medicine Surgery of the Third People’s Hospital affiliated to Fujian University of Traditional Chinese Medicine, the outpatient department of Traditional Chinese Medicine Hall of Fujian University of Traditional Chinese Medicine, the fifth representative inheritor of provincial intangible cultural heritage in Fujian Province, and the main inheritor of Chen’s academic school of traditional Chinese medicine surgery in Fuzhou, specializes in the diagnosis and treatment of skin diseases, alopecia, breast diseases, and TCM treatment of cancer after radiotherapy and chemotherapy.

Moderator: Hello, Dr. Chen, welcome.

Chen Boyi:Hello, host! Hello, netizens!

Moderator: When it comes to the academic school of Chen’s Chinese medicine surgery in Fuzhou, we have to mention a magical white powder, which is also commonly known as "Dan medicine". It is said that this "Dan medicine" is a "magic weapon" for Chinese medicine surgery to treat diseases. Dr. Chen, can you tell us what this "Dan medicine" is? What’s the magic effect?

Chen Boyi:This white powder, which we call "Bai Jiangdan", is a prescription left over by ancient medical scientists. During the refining process of Baijiangdan, its raw materials will undergo a chemical reaction and become air-flow sedimentation crystals, and the crystal color is white, so we call it Baijiangdan. Baijiangdan and Hongshengdan are two kinds of Dan medicines, which are in the bag of Chinese medicine surgeons. As the saying goes, "The three treasures of surgery: plaster, medicine promotion, and Bai Jiangdan." What’s the function of Baijiangdan, mainly to promote pus and remove putrefaction? It is mainly used to treat all kinds of difficult diseases such as scrofula, fistula, sores and so on, and it has an immediate effect on the erosion of the skin.

Moderator: In 2019, the production skills of Dan medicine of Chen’s school of traditional Chinese medicine surgery in Fuzhou were listed as the intangible cultural heritage of Fujian Province. Speaking of Chen’s academic school of traditional Chinese medicine surgery, can you tell us about the origin of this school?

Chen Boyi:The founder of Chen’s Chinese medicine surgery is my grandfather, Mr. Chen Gengyuan. He inherited the traditional Chinese medicine surgical skills handed down from his family, and learned from others’ "alchemy". In his early years, he practiced medicine in Taijiang, Cangshan and Yongtai, mainly using plasters and Dan medicine to treat surgical miscellaneous diseases, with remarkable results and a certain reputation in the local area. In the 1950s, when the Department of Traditional Chinese Medicine of Fujian Provincial People’s Hospital was established, he participated in the establishment and sat in the clinic. He was mainly good at diagnosing and treating surgical diseases of traditional Chinese medicine, and was also good at using some external plasters and pills. Influenced by his father-in-law, Mr. Zhao Feihan (a famous traditional Chinese medicine practitioner in Fujian Province) after marriage, when treating surgical diseases, he no longer confined to cutting and using external Dan medicine, but combined internal treatment with external treatment, which made him more handy in clinical diagnosis and treatment, thus forming Chen’s traditional Chinese medicine surgery. Later, to my father Chen Aoshi’s generation, my father’s first teacher was his grandfather, Mr. Zhao Feihan. Because my father studied poetry with his grandfather in a private school when he was 9 years old, he began to learn medical knowledge at the age of 13, starting with the medical three-character classic, the medicinal fu and the folk songs, and then further studying the classics of Chinese medicine such as Treatise on Febrile Diseases. At that time, my father laid a solid foundation of Chinese medicine. My father’s second teacher should be my grandfather, Mr. Chen Gengyuan. My grandfather sometimes goes to other places to seek medical treatment, so he learned Chinese medicine surgery and alchemy from my grandfather. My father is more diligent in clinical practice for decades, and he is diligent in thinking, learning from others’ strengths and taking part in internal and surgical courses, thus forming a unique clinical thinking.It is more handy in clinical diagnosis and treatment. Because of the exquisite technology, more and more patients come to see my father. Around 2000, at that time, registration depended on manual queuing, and some people began to queue up at the entrance of the National Medical Hall at three or four in the morning to hang my father’s number. At that time, my father was often invited to Shanghai, Nanjing and Hong Kong to consult and treat patients. With the vigorous development of my father, our academic school has been further inherited and improved. In 2019, it was recognized as "Fuzhou Chen’s Academic School of Traditional Chinese Medicine Surgery" by Fujian Provincial Health and Health Commission.

Moderator: What diseases are the Chen surgical academic schools in Fuzhou mainly good at treating?

Chen Boyi:From my grandfather to my father, they are mainly engaged in Chinese medicine surgery, so our school mainly inherits my father’s medical skills, mainly treating four kinds of diseases of Chinese medicine surgery, such as skin diseases, breast diseases, tumors and postoperative Chinese medicine conditioning, as well as some miscellaneous diseases of Chinese medicine.

Moderator: We know that the core idea of Chen’s academic school of TCM surgery boils down to nine words: attaching importance to qi and blood, being suitable for syndrome differentiation, and adding and subtracting. How do you understand this core idea?

Chen Boyi:Firstly, we attach importance to the important position of qi and blood in the occurrence, development and dialectical treatment of surgical diseases in traditional Chinese medicine, so we put forward the academic viewpoint of "emphasizing qi and blood" Pay attention to the application of qi and blood theory to guide clinical practice, mainly for guiding clinical practice, and pay more attention to regulating the ups and downs of qi and blood. Secondly, it is "appropriate dialectics". Chen’s traditional Chinese medicine surgery not only attaches importance to disease differentiation, but also emphasizes dialectical treatment. First, we should distinguish between yin and yang, whether it is yin or yang, whether it is exterior or interior, whether it belongs to cold or heat, whether it belongs to deficiency or excess. Second, it is necessary to pay equal attention to the whole and local syndrome differentiation. In addition to following the "eight-outline syndrome differentiation" and the methods of syndrome differentiation of viscera, meridians, qi and blood, it is also necessary to combine local symptoms, such as swelling, pain, pus, itching, numbness, ulceration and ulcer. We not only pay attention to the role of the whole body viscera, meridians and qi and blood disorders in the development of surgical diseases, but also pay attention to the influence of local lesions on the whole body viscera, meridians and qi and blood, so as to achieve the integrity of syndrome differentiation. Third, TCM surgical diseases are differentiated by stages. For example, the development of sores is divided into four stages: initial onset, suppuration, ulceration and granulation, and medication is also treated according to different stages. Thirdly, "adding and subtracting", besides following the classic theory, Chen’s traditional Chinese medicine surgical medication is not rigidly confined to the classics, but adopts the characteristics of adding and subtracting prescriptions by combining classic prescriptions with seasonal prescriptions, combining diseases with special drugs, and combining prescriptions with drug pairs. Second, while the general treatment principle is determined, it also takes into account the cause of addition and subtraction of drugs. Because of the sore, because of the "six lewdness and seven emotions",There are many causes of the disease, and the "six evils" are wind, cold, heat, dampness, dryness and fire, so it is easy for people who are weak to feel the attack. After the attack, it is necessary to refer to the treatment of cold, heat and cold, as well as the victory and defeat of evil. The third is to pay attention to the change of dosage. When using heavy dosage, the dosage should be increased, and when using small dosage, the dosage should be reduced.

Moderator: Now when it comes to TCM schools, it is very important to inherit. What do you think of the inheritance of Chen’s academic school of TCM surgery?

Chen Boyi:I think we should use "inheriting the essence, keeping integrity and innovating" to describe the future development direction of our school. "Upholding the Righteousness" is to keep the foundation of our Chinese medicine. For me, it is to adhere to the concept of "treating both inside and outside" of Chen’s school of Chinese medicine surgery, adhere to the principle of dialectical treatment and prescription medication in internal treatment, and create some new ideas and develop some new therapies in external treatment according to some new diseases in the new period. For example, acute and chronic eczema, acute and chronic urticaria, herpes zoster and postherpetic neuralgia, gout, plasma cell mastitis related to surgical diseases of traditional Chinese medicine, multiple hyperplasia of mammary glands, ovarian cysts, alopecia, etc., so we should sum up the clinical experience of our predecessors and explore the optimal diagnosis and treatment plan, so that our school’s thoughts can be passed down and benefit patients.

Moderator: Finally, there is a small question I want to ask you. Can you give us some tips to improve qi and blood?

Chen Boyi:When it comes to promoting qi and blood, we should actually talk about it from two aspects, one is to increase qi and blood, and the other is to stop its consumption. So you can’t overeat in diet, because overeating will damage the spleen and stomach, and you should eat less cold, spicy and irritating food. Be diversified in diet and eat some digestible food. And according to personal physique, according to the solar terms to do some tonic, generally regardless of season, we can eat some pork liver, medlar, longan, which can be eaten, especially peanut dumplings. Some people, who are weak in qi and blood, can also eat some raw land or stew ribs with Polygonum multiflorum Thunb. In daily life, you can’t stay up too late, because staying up late will damage Jingxue.

Moderator: Ok, today, I would like to thank Dr. Chen for visiting our studio and sharing with us many stories of Chen’s academic school of traditional Chinese medicine surgery. With the 5,000-year history of civilization, Chinese medicine is inclusive, forming a unique concept of life, health, disease and prevention, which embodies the integration and unity of natural science and humanities and contains profound philosophical thoughts of the Chinese nation. Inheriting traditional Chinese medicine is not only a treasure to protect China’s ancient science and culture, but also a key to open the treasure house of Chinese civilization. We believe that Chen’s academic school of traditional Chinese medicine surgery will surely pass on the excellent experience and academic thoughts of TCM diagnosis and treatment from generation to generation. Ok, that’s the end of this program. Thank you again, Dr. Chen. Thank you!

Chen Boyi:Thank you, host, thank you!

Moderator: Thank you for your attention. Goodbye.

　　The flexibility of hands determines that human beings become the dominant species on this planet. Intelligent manufacturing is also inseparable from a good "hand". Nowadays, industrial robots are an extension of people’s hands. They are all-around players who can do both rough and fine work. The connection of submarine immersed pipes can be done by "super welder" with one hand; The industrial master machine for processing optical molds can be "seamless"; Is there really a "solar system" on the robot arm carrying the girder? Who is the "holy hand" to do holographic physical examination and local surgery for super water conservancy projects?

　　Welding the world super project with robots

　　Make welding more efficient, more accurate and more reliable

　　The deep middle passage has two directions and eight lanes, and the diameter of immersed tubes is larger than that of the Hong Kong-Zhuhai-Macao Bridge. Each immersed tube weighs 9,000 tons, which is equivalent to a medium-sized aircraft carrier. A submarine tunnel is paved with 32 immersed tubes, which will be a world super project.

　　In the manufacturing base of steel shell of immersed tube for deep middle passage, a new immersed tube is about to start construction, which adopts sandwich structure.

　　As the name implies, the "sandwich" structure is a giant steel shell made of two layers of steel plates, and then concrete is poured between the compartments of the two layers of steel plates.

　　However, the giant steel shells are all welded, and the total length of the weld seam of each immersed steel shell exceeds 300 kilometers. If manual welding is used, a immersed steel shell needs more than 1,000 welders, and the construction period is as long as 12 months. If all 32 pipe joints are welded manually, it is obviously impossible to finish the task on time. This time, the engineer decided to start robot welding.

　　The robot measures the size and position of the steel plate, the brain sends instructions quickly according to the data, and the laser sensor on the welding gun tracks and identifies the weld, and corrects the deviation in real time.

　　If workers come to weld, they need to weld at least 6 to 8 times, and the robot can do it in one go, which is comparable to a "super welder".Long Hanxin, Chief Engineer of Project Management Department of GK01 Contract Section of Shenzhen-China Passage Project of Guangzhou Shipyard International Co., Ltd.With the same workload, we used to need 18 welders, but now we may only need 4 welders. Moreover, the quality of robot welding is relatively stable.

　　On the dock, the manufactured immersed steel shell is being lightered onto the ship. A pipe joint, the top surface area is equivalent to the size of 14 standard basketball courts. The flatness of the giant section reaches within 4 mm, and such high accuracy is rare in the world.

　　Hydraulic turbine maintenance robot

　　Repair the 41-year-old Gezhouba.

　　Gezhouba, the first large hydropower station on the Yangtze River, will celebrate its 41st birthday in 2022.

　　The runner is the "heart" of the generator set, and the water current drives the runner to rotate, converting as much energy as possible into electric energy. During normal operation, the surface of the runner is as smooth as porcelain, but the turbulent river brings energy, and at the same time, it also brings sediment to violently impact the runner surface, leaving uneven scratches, which seriously affects the health of the runner.

　　The 41-year-old Gezhouba is about to undergo a "major operation".

　　By manpower, it takes at least 3 weeks to repair a water turbine unit, and 3.6 million kilowatt-hours of electricity will be lost for one more day of repair. This time, the task of overhaul was given to the robot.

　　The robot is installed on the inner wall of the runner chamber of the hydraulic turbine, so that it can climb along the curved surface and work among the complicated impellers. Moreover, the polishing accuracy should reach micron level, which is more difficult than the doctor’s cosmetic surgery.

　　There is no precedent in the world for robots to overhaul large hydraulic turbines in situ. We will wait and see how the first generation of maintenance robots for hydraulic turbines perform.

　　In 2 hours and 20 minutes, the robot repaired two inner walls of nearly 1 square meter. The approval shows that the repetitive positioning accuracy of the robot reaches 0.06 mm, and the roughness of the machined surface is less than 1 micron, which is three times higher than the requirement.

　　In a narrow space, the robot is like a climbing Spider-Man, which can easily complete the maintenance of the inner wall and top blades of the runner. A robot can complete the maintenance work of 10 people in a week in 24 hours.

　　On May 18, 2022, the maintenance of the runner was completed, 30 days ahead of schedule. Intelligent solutions have given Gezhouba a new vitality.

　　Five-axis CNC machine tools are flowing.

　　Carve an electric guitar on the tip of a pencil

　　An optical mold part with a machined surface accuracy of micron level and a surface roughness of less than Ra10 nm can not be manufactured in batches by human hands, and it needs the help of precision CNC machine tools.

　　It takes nine knives to process this precision part, and each knife has a deviation of micron level, which is a small loss and a thousand miles away. It solves the problem of tool size error and is constantly approaching the highest standard in the international precision machining field.

　　The gap between the concave and convex surfaces of the workpiece is less than 5 microns, which is equivalent to one twentieth of the thickness of a piece of A4 paper, and the seam is really fit.

　　The adjusted five-axis CNC machine tool is like a pair of artists’ hands, carving a delicate electric guitar on the pencil tip with an area of only 10.35 square millimeters. Only when the axis motion accuracy of CNC machine tools reaches micron level can it be so smooth.

Fifteen years ago, the share of self-developed CNC system in domestic machine tool market was less than 1%, but now it has increased to 31.9%.

　　Domestic heavy-load robot

　　Every minute, you can complete the manufacture of the rear side panel of a car.

　　In the automobile factory in Wuhu, Anhui Province, 26 domestic heavy-duty robots are producing the rear side panels of automobiles. The wrists of these robots can carry 210 kilograms. They can accurately grab, feed and automatically identify the welds for welding, and can complete the manufacture of the rear side panels of a car every minute.

Today, about one-third of the world’s industrial robots are used in automobile factories. However, looking at 120 automobile factories in China, more than 90% of robots are imported from abroad. If it cannot be controlled independently, it will have a far-reaching impact on the whole industry, and domestic researchers should make up for this link.

　　Accuracy is the most difficult thing for a heavy-load robot to overcome. Today, the repetitive positioning accuracy of this 210kg heavy-load robot has reached 0.072mm, which is a step closer to the international first-class standard of 0.06mm..

　　There are hundreds of enterprises that produce industrial robots in China, but there are no more than 10 domestic companies that can mass-produce large-load multi-joint robots of more than 100 kilograms.

　　Heavy-load robot is a mountain that China robot enterprises need to climb urgently.

　　Accuracy retention reaches 0.3 arc minutes.

　　Chinese can finally produce a high-precision RV reducer.

　　In industrial production, robots that can take the lead often need to bear more than 50 kilograms, and the elbow joints of these pillars must use RV reducers with greater loads.

　　The annual output of industrial robots in China has reached 440,000. However, for a long time, 70% of RV reducers are foreign brands.

　　In 2015, Zhang Yueming, a professor at Beijing University of Technology, decided to challenge this domestic blank technology.

　　Turn on the RV reducer, which is like a solar system, with both sun gear and planet wheels. This is the cycloidal planetary gear of RV reducer. They are like planets around the sun, which have both rotation and revolution. They make 40 revolutions at the same time, and realize precise transmission through multiple planetary movements, which reduces the high-speed rotation of the motor and increases the torque to drive the robot arm to rotate.

　　After tens of thousands of times of repeated optimization, a unique design method of cycloidal planetary gear modification has been formed, which ensures that the profile errors of 39 tooth profiles are controlled within 4 microns.

　　After 100,000 tests, the accuracy retention of RV reducer reached 0.3 arc minutes, which completely solved the serious wear problem. Chinese can finally produce a high-precision RV reducer after crossing the rigorous micron manufacturing.

　　"China manipulator" stunning space

　　Cool as transformers

　　On November 17, 2022, the Shenzhou 14 astronaut went out to perform the mission. This is the first extravehicular activity after the T-shaped configuration of China Space Station is completed.

　　Working closely with the three astronauts are two "magic" mechanical arms.

　　The big robotic arm is called "Tianhe Robotic Arm", and its bearing capacity can reach 25 tons, so it can be called "Hercules" of China Space Station.

　　The small robotic arm is called "the robotic arm that asks for heaven". Although its bearing capacity is only 3 tons, it is very flexible.

　　Tianhe manipulator has two arms and seven movable joints, and its deployment length is 10.2 meters. Such a long manipulator must cover all working areas in zero gravity environment, and its accuracy must be less than 5 cm.

　　When the R&D team was at a loss, an engineer drew with compasses and was suddenly inspired. Just like compasses, they also let the two hands of large robotic arms act as "feet" and act as fulcrums for each other, alternately switching forward to realize crawling and transferring.

　　Young China engineers, who broke away from convention and made innovations, made Tianhe’s robotic arm perform tasks with a precision of millimeter, and accomplished the grasping of Tianzhou’s cargo cabin and the on-orbit indexing of the cabin. They were called "ever-changing King Kong" by netizens.

China’s research and development of space manipulator is 40 years behind the world’s, but the speed of our progress has amazed the world.

　　In August, the economic recovery trend in Jiangsu Province was significantly enhanced. Compared with last month, the growth rates of industry, service industry, investment and consumption all showed an upward trend. From January to August, the industrial added value, investment in fixed assets and total retail sales of social consumer goods in Jiangxi Province increased by 7.3%, 8.5% and 5.6% respectively, which were higher than the national average … … The economic "transcripts" handed over by many places recently show that the economy continues to recover.

　　However, some places also said that the current external situation is still complicated and severe, domestic economic recovery still faces many difficulties and challenges, and the foundation for sustained economic recovery still needs to be strengthened.

　　How to stabilize the economy? The recent the State Council executive meeting intensively deployed this, emphasizing that "while implementing the package policy of stabilizing the economy, 19 successive policies will be implemented to form a combined effect, so as to promote the economic stabilization and keep the operation in a reasonable range". Streamline administration, delegate power, strengthen regulation and improve services ’ The reform measures will further promote the effectiveness of the package policy of stabilizing the economy, refine the implementation policy, and implement the detailed rules in early September. ""All localities should shoulder the responsibility of stabilizing the economy and protecting people’s livelihood, and provinces with large economies should take the lead and work together to consolidate the foundation of economic stability and promote stability. "

　　From Jiangxi’s promulgation of "Several Successive Measures to Effectively Stabilize Economic Development" to Gansu’s formation of 24 policies and measures to stabilize the economy, and then to Shanghai’s emphasis on implementing a new round of national and municipal policies … … At present, while implementing the national macro-policies, all localities have further enriched the policy toolbox around areas such as expanding effective demand and stabilizing market players to protect people’s livelihood, so as to ensure the sustained release of policy effects.

　　— — Give play to the key role of effective investment

　　On September 22nd, the construction of Huaihong Xinhe Irrigation District in Anhui Province started with a total investment of 10.4 billion yuan. So far, all the six new large-scale irrigation projects promoted by the State Council this year have started. On September 21st, the centralized commencement of major water conservancy projects in Hubei Province was held at the site of the second phase of water resources allocation project in northern Hubei. The total investment of 19 projects started this time is 27.48 billion yuan, which will promote the construction of Hubei as the first batch of provincial water network pilot areas in China.

　　Expanding effective investment is a key link in the policies and measures to stabilize the economy in various places. For example, Henan proposed that, in order to make full use of the economic stabilization package and the dividends from the following policies and measures, seize the key period and fight for the red throughout the year, we will focus on tackling key problems in important economic stabilization projects. Give play to the key role of effective investment in stabilizing the economic market, realize the annual growth of fixed assets investment by more than 10%, complete 2.8 trillion yuan, and strive to achieve an economic growth rate of more than 5.5% in the second half of the year, and the annual economic aggregate exceeds 6.3 trillion yuan.

　　Jiangxi said that it will seize the policy-oriented development financial instruments and special bonds to increase the scale, expand the opportunities in the field, strengthen the project to sort out the reserves, accelerate the preliminary work of the project, win more support from the state, and ensure that the first batch of contracted projects will start construction before the third quarter. According to the principle of "landing, solid support and quick results", we will implement the "four major actions" of urban shantytown renovation, "big traffic" construction, rail transit in Nanchang metropolitan area and infrastructure construction in water conservancy, with a total investment of over 1 trillion yuan.

　　— — Promote the accelerated recovery of the consumer market

　　In Jiujiang City, northern Jiangxi Province, an online launching ceremony was held a few days ago for the Jiujiang Branch of the 2022 Jiangxi "Hundred Cities and Hundred Nights" Cultural and Tourism Consumption Season. During the event, nearly 100 supporting activities such as non-legacy shopping festival, camping music festival and food carnival will be held in counties (cities, districts) of Jiujiang City. According to the relevant staff of Jiujiang Wenguang New Tourism Bureau, the local government takes the creation of a national-level night cultural tourism consumption gathering area and a provincial-level cultural tourism consumption pilot city as the starting point, and actively cultivates a night consumption industrial system integrating night sightseeing and recreation, special catering, fashion shopping, cultural performances, fitness and entertainment, and immersion experience to further tap the consumption potential of domestic demand.

　　In order to further accelerate the recovery of consumption, many places have made great efforts in promoting mass consumption and promoting the recovery of service industry. For example, Jiangxi emphasizes that it will continue to implement the vehicle purchase tax exemption policy for new energy vehicles and encourage new energy vehicles, smart home appliances and green building the countryside. Fully activate the consumption of business travel, continue to implement various policies to promote consumption, and study and introduce policies and measures to support the recovery and development of catering and accommodation industries.

　　With the main promotion activities as the carrier, key consumption season activities will also appear one after another. Gansu proposed to organize a three-month key consumption season of "Enjoy Consumption and Buy Longyuan" in combination with the consumption promotion activities such as "2022 International Consumption Season", "100-city Linkage Automobile Consumption Season" and "National Household Appliances Consumption Season" organized by the Ministry of Commerce. Hainan proposed to issue 50 million yuan travel vouchers to tourists outside the province and 100 million yuan vouchers to residents in the province.

　　— — Boost the development confidence of market players

　　The key to stabilizing the economy lies in protecting market players. Many places have made great efforts to grasp the important window period and opportunity period of economic recovery, and made every effort to solve outstanding problems such as insufficient demand, weak confidence and weak expectations in the current economic operation, and adopted various measures to stimulate the vitality of market players and enhance market confidence.

　　Shanghai said that it is necessary to implement a new round of policies of the state and the city on the basis of the previous implementation of the policy of helping enterprises to bail out difficulties, increase financial subsidies, tax relief, rent relief and other support, and take out real money to boost corporate confidence. Focus on all kinds of problems that affect economic development, find out the bottlenecks faced by enterprises in time, and study targeted measures in time.

Historically, rice once occupied a supreme position in Japanese life. The Japanese once thought that food was rice, and eating rice was nothing more than adding salt. There is even a saying in Japan that "rice is rich in salt" means that as long as there is rice and salt, there is life. But now, according to a survey conducted by NHK (Japan Broadcasting Association), "Ramen (Lamian Noodles)" has become the Japanese favorite food in the New Year-noodles have reached the top of food in this rice country.

Why didn’t ancient Japanese eat wheat?

There is a folk legend in Japan that "the fox stole an ear of rice from China and took it back to Japan in a bamboo tube", so that Japan had rice. Through this legend, we know that Japanese rice culture was spread from China, and there are two ways to spread it: first, it passed through Jiangsu and Shandong, and crossed the sea from Shandong Peninsula to the south of the Korean Peninsula; The other is introduced into the northern part of the peninsula by land from North China to Northeast China, and then spread to the south. Both reached the same goal by different routes, and spread to Japan through Ma Haixia. This can be seen from the early remains of paddy fields in Japan-archaeological discoveries in the coastal area of Fukuoka in the northern part of Kyushu Island, which is closest to the southern tip of the Korean Peninsula. Subsequently, the rice cultivation technology gradually spread to the south and east with the northern part of Kyushu as the center. By the 3rd century AD, it had spread to Shikoku Island and most parts of Honshu Island. The grains unearthed in the sites of Yayoi and Gufen from the 3rd century BC to the 7th century AD were all rice.

Because the water and heat conditions in the Japanese archipelago are suitable for rice planting, and compared with planting coarse cereals in dry fields, rice planting is labor-saving, time-saving and high-yield. Therefore, for thousands of years, Japan’s rice production has been the first of all kinds of crops. Therefore, the Japanese call rice the king of food, and rice is a gift from heaven to Japan. Japanese people are used to eating rice, so in the history of ancient Japanese agriculture, barley and wheat are rare. In ancient Japan, people even thought it was time-consuming to eat pasta, but the saying that "the poor eat wheat" was repugnant to pasta. Although in famine years, Japanese officials often encourage the cultivation of wheat to alleviate famine and distribute seeds; However, farmers refused to buy it. Even if they were forced by the government to plant wheat, they refused to eat it as food. Instead, they cut it before it matured and sold it as horse feed, so that the Emperor had to issue a decree in 715 AD announcing that if the immature wheat was sold as horse feed, it would be severely punished.

Is it really that the taste of wheat doesn’t agree with the Japanese? In fact, it is not. The fundamental reason for boycotting wheat planting is actually that Japan lacked the technology to make flour at that time. Before the era of mechanized mass production, ancient people used a stone mill to make flour. In China during the Sui and Tang Dynasties, firstly, the stone mortar was pushed by human or animal power to process flour, and then the flour was milled by water truck, thus reducing the price of flour, making it possible for ordinary people to eat pasta, and thus making pasta appear and popularize in large numbers. According to the Japanese history book "The Book of Japan", as early as 610 AD, a Koguryo monk named Tanzheng brought the stone mill to Japan, but the Japanese couldn’t copy it. To make a stone mill, it was necessary to carry out precision processing on hard stones. However, the stonework technology in ancient Japan was underdeveloped, and it was really beyond their power to produce the stone mill. At that time, Japanese people could only grind flour with wooden mortar and pestle, but wooden mortar and pestle were only suitable for pounding rice. When wheat with hard bran was encountered, it was quite laborious to pound it, and it became very difficult to make pasta. Unlike wheat, which needs to be ground into powder to eat (the seed coat of wheat is hard, so it is very unpalatable to eat it directly), millet can be cooked directly as long as it is washed, and even eating brown rice unexpectedly makes up for the vitamins and minerals that Japanese people lack in their daily diet. After the Meiji Restoration, the Japanese army generally ate polished rice, but beriberi caused by vitamin deficiency appeared on a large scale. As a result, contrary to the folk saying that "the poor eat wheat", for a long time,Japanese pasta has become a kind of precious food monopolized by officials, nobles and senior monks.

Plain noodles, udon noodles, buckwheat noodles

When it comes to pasta, we can’t help but mention noodles. In 2002, in the Qijia cultural layer of the Neolithic age in Qinghai Province (the Neolithic culture in Gansu Province from 2200 BC to 1600 BC), archaeologists unearthed noodles made of millet and millet 4000 years ago, which were about 50 cm long and 0. 3 cm wide, even in thickness and bright yellow in color. This is probably the earliest known noodles. China’s invention right of "noodles" is therefore beyond doubt.

Ancient noodles unearthed in Qinghai

Before the Tang Dynasty, all foods made of wheat flour were called "noodles", and foods such as noodles, which were heated by putting wheat dough in boiling water, were called "soup cakes", but in the Song Dynasty, "noodles" were separated from "cakes" to refer to "noodles" exclusively. In Meng Liang Lu, written by Wu Zimu, which describes the bustling scene of Lin ‘an (now Hangzhou) in the Southern Song Dynasty, a noodle shop has been set up, including "silk chicken noodles", "three fresh noodles" and "fried chicken noodles", which is no different from today.

Although there was no communication between China and Japan at the national level in Song Dynasty, the cultural and economic exchanges between the two sides were still frequent. Different from the official "envoys to the Tang Dynasty", Japanese monks who entered the Song Dynasty played a vital role in the exchanges between the two sides. At that time, when Zen Buddhism was flourishing in China, most Japanese monks also wanted to study in China. While introducing Zen Buddhism to Japan, they also brought back the food culture of China monasteries at that time (all vegetarian, of course), and noodles were one of them. Some people in later generations concluded that "most epoch-making Japanese food comes from monasteries and is generally spread by monks who have experience in studying in China".

In 1241 AD, the founder of Tofuku-ji Temple in the south of Kyoto today, Shengyi Kunshi, returned from China and brought back a "water mill map" (a design of a mill made of waterwheels and gears), which finally made Japanese flour-making technology catch up with China’s level. From then on, Japanese people can taste pasta, which used to be exclusive to monks and nobles, and gradually change their views on pasta.

What noodles did the ancient Japanese eat? The first thing that was welcomed by the Japanese was Su (Suo) noodles. Vegetarian noodles are the earliest Japanese noodles. At that time, the vegetarian noodles were all stretched by hand after the dough was kneaded repeatedly, just like the handmade Lamian Noodles, which was characterized by being long and thin, refreshing to eat, and mainly used as cold food. Next came the famous udon noodles, which were made by slicing thin dough into hot soup noodles. It is said that the troops of Takeda Shingen, the famous "Tiger of Jiafei" in the Warring States Period, used udon noodles as their food for marching. It stands to reason that udon noodles can only be made by rolling the dough thin with a rolling pin and then cutting it with a knife. Unlike making vegetarian noodles, it takes high technology to pull the dough into long strips first, but in fact udon noodles appeared in Japan as late as the 15th century. Investigate its reason, it is because the technical level of the Japanese at that time was too poor to make a chopping block! It takes a planer to make a chopping block, but it didn’t become popular in Japan until the Edo period in the 16th century. Before that, workers needed to put the blade on the front end of the stick and flatten the wood bit by bit to make a chopping block, which was very laborious.

The buckwheat noodles appeared later than udon noodles. Buckwheat itself is not sticky and easy to break, so it is not suitable for making noodles. Legend has it that in 1659, Zhu Shunshui (1600-1682), a adherent of the Ming Dynasty who stayed in Mitofan (now Ibaraki Prefecture), taught the Japanese to mix wheat flour into buckwheat flour to make it sticky and elastic, so this kind of noodle called "the most Japanese characteristic" came out. One of the reasons why soba noodles are popular is to win the favor. It is said that Japanese gold foil masters, at work, often use soba dough to touch the gold foil fragments that take off and fall everywhere. To this end, Japanese folks think buckwheat is a cash register item, so they use its auspicious saying to prepare buckwheat noodles when they are engaged, married or celebrating. Eating buckwheat noodles every other year on New Year’s Eve is also for good luck, hoping for gold and silver to enter the home, which is a mentality with China’s "more than fish every year". By the 19th century, Edo (now Tokyo), a city with a population of 1 million, had a list of 100 buckwheat noodle shops, which showed the Japanese people’s enthusiasm for this kind of noodle at that time.

The Birth of "Lamian Noodles"

The same is noodles, whether udon noodles or buckwheat noodles. An important difference between Japanese noodles before modern times and Chinese noodles is that Japanese noodles are made without adding alkaline water. When wheat flour meets water, it will produce a grid-like tissue, commonly known as "gluten". Alkaline water is a kind of alkaline natural soda water containing potassium carbonate and sodium carbonate. When Chinese noodles are made, alkaline water is added, so the kneaded dough can change the protein in flour, enhance the viscosity and elasticity, and make the taste more comfortable.

正宗的中国面条迟至19世纪末、20世纪初才进入日本。1893年时，日本横滨的外国人居留地中居住着约5000名外国人，其中中国人约为3350人。而在甲午战争之后，清朝开始向日本派遣官费留学生，以后自费留学生的规模也急剧扩大。在1905年前后，在日本的中国留学生人数达到大约5万人。与此同时，无论是梁启超这样的立宪派，还是孙文这样的革命党，都将日本作为重要的活动据点，如此众多的中国人在短时间内来到日本，势必又一次将中国的饮食文化带入东瀛四岛。

大约在20世纪初期，中国面条出现在了横滨的“南京町（唐人街）”，并从这里出发，迅速征服日本人的脾胃。值得注意的是，当时的日本一心脱亚入欧，断发易服之外，连饮食也恨不得一日西化，著名思想家福泽谕吉撰文鼓吹要像西洋人一样“应该吃肉”（此前受佛教影响，日本人几乎不吃鱼肉之外的肉类）。明治天皇带头喝牛奶吃牛肉，当时的日本宫廷膳食干脆就是法式大餐。相反，对于传统的文化母国，日本则是一副鄙薄心态，印度古籍用于指代中国的“支那”一词正是在这一时期，在日本人的口中出现了贬义。在这样的背景下，中国面条在日本的传播，完全是出自食物本身的魅力。

尽管这种中国面条毫无荞麦的成分，但比起粗粗圆圆的乌冬面，形式上更接近固有的细长的荞麦面，被日本人称为“南京荞麦面”，并以其价格低廉、滋味鲜美而受到日本中下层市民的欢迎，逐渐走出“唐人街”，在日本主流社会中流行开来，名字也变成了“支那荞麦面”。第二次世界大战之后，迫于作为战胜国的中华民国政府的压力，日本官方不得不下令禁用“支那”一词。结果，不知从何时起，“支那荞麦面”又变成了“ラーメン”。这个假名的读音“ramen”极似普通话的“拉面”，显系晚近从汉语里直接借入的外来词。

Lamian Noodles has become a national delicacy in Japan today, mainly because the long Lamian Noodles can be matched with various vegetables and animal meat as the main materials, and seafood such as soy sauce, ginger, onion, sesame oil and various scallops or shrimps can be added to meet the dietary needs of all social classes. Therefore, there is a "Chinese Noodle Noodle Center" in Fukuoka, a "New Yokohama Lamian Noodles Museum" in Yokohama, and even a "Japan Lamian Noodles Research Association", which specializes in Lamian Noodles magazine … Lamian Noodles has become a well-deserved king of Chinese cuisine circulating in Japan.

Hubei Daily News (Reporter Jassamyn Liu, correspondent Liu Chang, Li Xingde) On April 25th, it was learned from Wuhan Hanyang Urban Management Law Enforcement Bureau that in order to facilitate the visually impaired to travel, the bureau laid a new type of hot-melt blind road on several roads, which will be gradually promoted in the whole region in the future.

On Jiangcheng Avenue in Hanyang District, blind people walk on the new hot-melt blind road in this section, and there is obvious concave and convex feeling under their feet. The strip-shaped blind brick indicating the heading direction is basically the same as the permeable concrete pavement on both sides, and there is no discomfort when accidentally stepping on the brick surface. During the hundreds of meters’ journey, except for the tension caused by "invisibility", there is no feeling of slipping under the feet.

According to the relevant person in charge of the Municipal Facilities Management Section of Hanyang Urban Management Law Enforcement Bureau, in the past blind road construction, concrete blind road bricks were mostly used, which were mainly laid on sidewalks. In order to ensure the practicability, safety and humanization of blind roads, Hanyang Urban Management Law Enforcement Bureau draws lessons from advanced practices and listens to the opinions and suggestions of visually impaired people, taking Jiangcheng Avenue, Mohe Hubei Road and Longyang Avenue as the pilot, and gradually adopts hot melt technology to build blind roads in the whole district.

Hot-melt blind road pavement is fast, and traffic can be opened in 20 minutes after on-site construction. "Compared with the traditional concrete blind road brick, the hot-melt blind road is more durable, wear-resistant and corrosion-resistant, and has good identification and anti-slip, which is more friendly and safer for blind friends." The person in charge introduced.

In view of the problems existing in urban blind roads, the bureau will continue to adjust some details, such as the conflict between blind roads and piles, the irregular setting of stone-missing ramps or kerb ramps, and the discontinuous interruption of blind roads, so as to ensure the safety and smoothness of visually impaired people’s walking to the greatest extent.

According to statistics, since 2023, Hanyang District Urban Management Law Enforcement Bureau has concentrated its efforts on the rectification of blind roads, such as subsidence, dislocation, breakage, looseness, lack, continuous unreasonable turning around of blind roads and obstacles on blind roads. Up to now, 837 blind roads with an area of 2,114 square meters have been rectified.

　　Xinhua News Agency, Fuzhou, July 9 (Reporter Zhang Huaying) A few days ago, the reporter learned from the Wuyishan National Park Scientific Research Monitoring Center that during the background investigation of biological resources in Wuyishan National Park, researchers discovered five new insect species of the genus Euonymus, namely, Euonymus brevis, Euonymus versicolor, Euonymus versicolor and Euonymus versicolor. At present, relevant scientific research results have been published in the Journal of Insect Taxonomy.

　　In April 2021, Wuyishan National Park Administration launched a three-year background survey of biological resources. More than 100 experts from many scientific research units and universities went to the field many times to comprehensively investigate the main ecosystems and biological groups of Wuyishan National Park. Up to now, 24 new species have been found in the survey. During the investigation, researchers collected a large number of insect samples, observed the morphological characteristics of adult samples through stereoscope and microscope, and identified them as new species by means of morphological taxonomy.

　　Ma Fangzhou, an associate researcher at the Nanjing Institute of Environmental Sciences of the Ministry of Ecology and Environment, said that the yellow-shouldered dance insects are generally small in size, with the adult body length ranging from 1.8 mm to 2.8 mm, the male insect’s abdominal end is thick and the female insect is slender. Their larvae live under the ground cover, rocks or soil, and adults are terrestrial, mostly moving on the surface and ground of plants. Preying prey mainly includes psyllids, aphids, scale insects, mosquitoes, flies, mites and other important economic pests or health pests.

　　Ma Fangzhou said that the new species of Rhopalosiphum discovered this time plays an important role in clarifying the insect resources of Rhopalosiphum, and at the same time, it is of great significance in the comprehensive management of pests by biological control and the study of indicator organisms for biodiversity and environmental assessment.

-DRAGON BOAT FESTIVAL

The origin of the Dragon Boat Festival

"The Dragon Boat Festival originated from the totem sacrifice held by the tribes who worshipped the dragon totem in ancient times. It was a festival founded by the ancestors to worship the dragon ancestors and pray for evil spirits. During the Warring States Period, the patriotic poet Qu Yuan threw himself into the Miluo River with a boulder on the Dragon Boat Festival, so later generations also took the Dragon Boat Festival as a festival to commemorate Qu Yuan."

Dragon boat festival custom

First, dragon boat race

Dragon boat race is the main custom of Dragon Boat Festival. According to legend, in ancient times, Chu people were reluctant to let Qu Yuan, a sage, die in the river. Many people rowed boats to catch up with the rescue, and then rowed dragon boats every May 5 to commemorate Qu Yuan.

Nowadays, dragon boat race has become one of the most important folk activities in China Dragon Boat Festival. Dragon boat rowing has a long history. It is a traditional folk water sports and entertainment project in China since ancient times. It is mostly held on festive festivals and is a multi-person collective rowing competition.

Second, eat zongzi

Legend has it that after Qu Yuan’s death, people put rice in bamboo tubes and threw it into the river in order not to damage his body. From then on, in order to show respect and memory for Qu Yuan, on this day, people put rice in bamboo tubes and threw it into the river to pay homage. This is the origin of the earliest zongzi "tube zongzi" in China.

Eating zongzi at the Dragon Boat Festival is a traditional custom of the Chinese nation since ancient times. It has a long history and various patterns. Zongzi was originally used to worship ancestors and gods. The custom of eating zongzi on the Dragon Boat Festival is popular in China, and spread to Korea, Japan and Southeast Asian countries.

Third, hang sachets

Dragon Boat Festival sachets, also known as sachets, sachets, purses, etc., are made of five-color silk thread and filled with Chinese herbal medicines and spices. Its manufacturing process has become a national intangible cultural heritage. Now it has become a unique folk art of the Dragon Boat Festival.

Fourth, tie colorful ropes

On the Dragon Boat Festival, when children wake up, their wrists and ankles have been tied with "five-colored ropes" woven with colorful silk threads. Adults say that if they are tied, they will not be invaded by all diseases. After the first rain after the Dragon Boat Festival, cut off the five-color rope and let the rain wash away, and the disaster will be taken away with it.

With regard to the five-color line, the customs in different places are similar. Some of them are tied with five-color silk, or hung at the door, or worn by children’s necks, or tied by children’s arms, or hung in bed curtains, cradles, etc., which is said to avoid disasters, protect health and prolong life.

Five, hanging mugwort leaves

A folk proverb says, "Willows are inserted in Qingming Festival, and Ai is inserted in Dragon Boat Festival". People think that May is a poisonous month, and the fifth day is a poisonous day. Every May, it is the time when Artemisia argyi is mature and has the best medicinal properties, so people have to pick Artemisia argyi in the wild during the Dragon Boat Festival. Acorus calamus and Artemisia argyi leaves are hung in front of the door and eaves to prevent plague and avoid disaster, and hung on the door and bedside to avoid evil spirits.

Six, eat duck eggs

In addition to commemorating Qu Yuan, the Dragon Boat Festival is to avoid five poisons, namely snakes, centipedes, spiders, geckos and scorpions. People use five kinds of red dishes to symbolize the blood of the five poisons. When eating these dishes, they are roast duck, amaranth, duck eggs with red oil, lobster and realgar wine. Therefore, eating duck eggs on the Dragon Boat Festival has a certain color to ward off evil spirits. From a scientific point of view, eating duck eggs is to preserve health and dispel summer heat.

Seven, drink realgar wine

It is said that drinking realgar wine can ward off the five poisons. The custom of drinking Pu wine and realgar wine has been circulating for a long time. After soaking in wine, people use Acorus calamus and Aipeng to dip in the corners of walls, doors and windows, under the bed, etc., and then use wine to coat the ears, nose and navel of children to ward off poisonous insects. From the health point of view, realgar can be disinfected by adding water and wine indoors, and drinking Pu wine is also quite beneficial.
