　　In recent years, behind many academic misconduct, there is a secret paper trading industry chain, and some third-party institutions buy and sell papers, plagiarize and cheat under the guise of "polishing papers".

　　Cheng Shuozuo (Xinhua News Agency)

　　"SCI journals are the most important and reliable, and the number is limited. Pay after employment." Xiao Zhao, a doctoral student in a university in Beijing, received an e-mail titled "Reply: Submission" when his mobile phone screen lit up. When he clicked into the text, he found that this paper was written to advertise.

　　"This is the third letter I have received this month." Xiao Zhao wrote to this newspaper that he often received similar emails.

　　Writing papers instead of publishing them violates scientific research integrity and erodes scientific research spirit. Nowadays, some paper intermediaries turn to online platforms. How do they work? Why is it repeatedly banned? The reporter conducted an investigation.

　　Businesses that write and send papers are all over the network platform, claiming that they can buy papers with money.

　　"As long as there is ‘ in Weibo; Paper ’ In two words, there may be an account for writing papers ‘ Like ’ 。” Xiao Su, a master’s graduate, said that she encountered this situation many times when writing her thesis.

　　The reporter tried to publish a Weibo with the word "paper". In less than 10 minutes, it was called "Shuo — On — Generation — The account of "Write" likes it, and its homepage profile says "Write MBA, MPA, master’s thesis, periodical publication, etc., and write the team professionally to ensure quality", and leave the QQ number.

　　"It is easy to find relevant information on the Internet." Wuyishan, a researcher at the China Academy of Science and Technology Development Strategy, said. With the rapid development of Internet and computer communication technology, the communication channels of papers are more extensive, the communication speed is faster, and more people are contacted.

　　Reporters input "papers" on Baidu, sogou and other search engines, and there are websites on the front pages. Some introductions say, "Strictly follow the writing requirements, standardized format and delivery time, and multi-disciplinary professional teachers provide high-quality auxiliary guidance", and some advertisements say, "The agent publishes quickly, the editor-in-chief receives the manuscript directly, the process is short, and the page fee bill is provided, so you are a reliable paper publishing partner". On Taobao, QQ, WeChat, Zhihu and other platforms, you can also find "merchants" and users related to writing and forwarding papers.

　　The reporter contacted a number of businesses in the name of writing and publishing papers. When searching to join the relevant QQ group, a user took the initiative to ask: "Write a paper?" The reporter inquired about the charge for writing undergraduate graduation thesis, and the other party said that 900 yuan, a thesis with 10,000 words and a repetition rate of less than 10%, would "start the topic, check the duplicate and report".

　　When the reporter hesitated whether it was "reliable", the other party sent a screenshot and said, "We do this every day." There are more than 20 documents on the map, and the topics are related to accounting, real estate, photovoltaic power generation and so on.

　　In a paper publishing agency group, members nicknamed periodical editors constantly publish information: "The agency can receive it directly, check the manuscript, make it public, and have invoices", "Wanfang will include it, keep it online, and return it in full if it is not online" … …

　　A user nicknamed the editor of a periodical recommended a periodical, saying that it is regular and accessible, and the publishing cost is about 800 yuan, "depending on how many characters you write". The reporter wants to confirm whether it can be published. The other party said that "the article is clear in logic, coherent and smooth before and after, and generally no problem", and said that the layout is tight, so it is best to grasp the operation. On Wanfang platform, we can find that this journal is a weekly magazine. Taking the latest issue as an example, there are more than 200 articles, and the authors come from companies, grassroots governments, township schools and so on.

　　It is worth noting that some agents can also write or help contact them. "I can help you contact and see what you need," said the editor. The ghostwriting fee is generally from 100 yuan to 300 yuan. A "thesis consultant" of "China paper net" also made it clear that it can be written on behalf of others, and sent four periodicals and their prices, some of which were "2200 characters for the first edition, 1850 yuan for writing on behalf of others" and some were "3000 characters for the first edition, 2100 yuan for writing on behalf of others".

　　Xiao Zhao received an email saying that he could help publish SCI journals, "no down payment, 0 down payment, payment after the journal is officially hired, and no charge if it is unsuccessful". After the reporter consulted, the other party sent a picture showing that the price ranged from 20,000 yuan to 100,000 yuan according to the periodical division and impact factors.

　　Demand is large and profitable, and some "merchants" have changed their faces and taken risks.

　　According to the "Several Opinions on Further Strengthening the Construction of Scientific Research Integrity" issued by the Central Office and the State Council in 2018, the market supervision and management, public security and other departments should take the initiative to investigate and severely punish intermediary service institutions engaged in illegal activities such as buying and selling academic papers, writing and investing on behalf of others, and forging, fabricating and tampering with research data.

　　The reporter found that many platforms have blocked keywords such as "writing papers", but they are still banned repeatedly, just changing their faces and evading supervision.

　　For example, in Sina Weibo, a search for "papers to write" indicates that "according to relevant laws, regulations and policies, the search results are not displayed". However, there are still a lot of results when searching by ghostwriting, and some "hot" Weibo likes them by thousands and forwards them by hundreds. In Taobao, there are some products called "Guidelines for Writing and Publishing Academic Papers". After the reporter consulted, the "merchants" sent the prices for writing and publishing. Searching on QQ with "thesis" as the key word has a large number of groups. The reporter joined a group with 1988 members, and the user "Golden Pen Studio" said, "The students who need to write on behalf of this group have a private chat with me." There are also some websites, wearing the vest of "paper cloud platform" and "periodical information", which are engaged in writing on behalf of others.

　　Wuyishan said that effective supervision mechanism and legal restraint mechanism are still lacking. The reporter also found that although it is easy to search online, the follow-up communication is hidden. Most of the other parties request to add private chats such as QQ and WeChat, and some payments are also made through WeChat, which brings inconvenience to supervision.

　　In addition to the regulatory difficulties, behind the repeated prohibition of writing papers on behalf of others, there is still a large number of demand and supply.

　　"I know students who haven’t sent an article in the fourth and fifth grades. Sometimes they are too worried to sleep." Xiao Zhao said that in his department, generally speaking, doctoral students need to publish at least two SCI journal papers after graduation, and some students are under great pressure to publish.

　　It is not only masters and doctoral students who are facing the demand of writing and publishing papers. "Now, the total number of people who have the hard task of writing scientific research papers is very large." According to Kunlun Zhang, a professor at Henan University, the total number is in the tens of millions, including full-time teachers in colleges and universities, graduate students, full-time teachers in high schools and junior high schools, as well as scientific researchers and engineers and technicians other than colleges and universities, as well as technicians in agriculture and health industries. Wuyishan also believes that it does not mean that the unreasonable requirements for publishing papers will be cancelled, and papers will be extinct. "Some people may still cheat in order to pursue better interests in the process of awarding prizes."

　　From the supply point of view, the risk of writing papers on behalf of others is low and the return is high, with income ranging from thousands of yuan to tens of thousands of yuan. The reporter also learned that compared with the income, its cost is lower, most of the income belongs to the intermediary, and the writer gets less income.

　　In addition, the service of writing on behalf of others can be called "thoughtful", and some "merchants" not only provide one-stop service of writing on behalf of others, but also have a warm attitude. A few days after the reporter’s consultation, the "merchants" also took the initiative to remind them that if the topic selection of the paper is difficult, they can help to set the topic and pay attention to the deadline … …

　　The demand is still strong, the supply is continuous, the supervision is facing difficulties, and the multiple factors make the Internet paper generation platform still emerge one after another.

　　Experts suggest perfecting laws and regulations, strengthening network supervision, and reasonably defining the requirements for publishing papers.

　　"If this continues, it will be extremely unfair to those who really sit on the bench and work hard to explore the unknown and study science and technology." Kunlun Zhang said that the drawbacks caused by the publication of papers in money transactions are serious, and should be dealt with severely with a combination of boxing.

　　Kunlun Zhang believes that the punishment measures formulated by relevant laws and regulations are relatively thin, and there are also problems of inadequate law enforcement in reality. He suggested that laws and regulations should be improved, and it should be clearly stipulated that commercial institutions that write and distribute papers are illegal, and commercial acts of writing and distributing papers are illegal.

　　"On the basis of clear laws and regulations, the press and publication management institutions at all levels and the public security network supervision departments should work together to resolutely eliminate websites and advertisements that publish papers for compensation, and investigate the legal responsibilities of intermediaries and relevant journals." Kunlun Zhang said.

　　Wuyishan also believes that, in view of the fact that most of the advertising and trading activities of papers are carried out through the Internet at present, it is suggested that the network supervision department set up a filtered vocabulary of related words, so that intermediaries can’t publicize through the Internet, and demanders can’t access relevant information on the Internet, which will increase the difficulty and cost of their publicity and trading.

　　In addition to the governance of the platform, we should also make efforts from the demand side, such as reasonably defining the requirements for publishing papers for the promotion of professional titles of relevant practitioners.

　　“‘ Paid publication of papers ’ The persistence of high fever is closely related to the rigid requirement of publishing papers for the promotion of professional titles of science, education and health technicians. The criteria for evaluating the professional ability of science, education and health technology practitioners should be diversified, and the specific situation needs specific analysis. " Kunlun Zhang suggested that some positions can be promoted without publishing papers, while others can only use publishing papers as an auxiliary condition rather than a rigid condition of "one-vote veto". In terms of degree awarding, the requirements for publishing papers of different degrees can also be different.

　　In October 2018, the Ministry of Science and Technology, the Ministry of Education, Ministry of Human Resources and Social Security, the Chinese Academy of Sciences, and the China Academy of Engineering issued the Notice on Carrying out the Special Action of Cleaning up "Only Papers, Only Professional Titles, Only Academic Qualifications, Only Awards". Wuyishan believes that if the action of cleaning up "only papers" can be put in place, it will help to manage the chaos from the demand side.

　　Academic journals are also the link to manage the distribution of papers. Kunlun Zhang said that it is necessary to create a mechanism in which journals don’t want to sell their pages and are afraid to sell their pages. From the perspective of internal mechanism, we should improve the quality of running journals, formulate rigid severe punishment measures, and severely deal with those who sell pages privately for profit. From the perspective of external mechanism, external law enforcement inspection and supervision should be strengthened.

　　Of course, researchers should strengthen self-discipline, and those who finish and publish papers through improper means should be punished more severely. "If there is a problem with integrity, one vote veto will do!" Wuyishan said.

　　Chongqing is located in the upper reaches of the Yangtze River and the heart of the Three Gorges reservoir area, which is an important ecological function area in China. In recent years, the vegetation in the ecological barrier area along the Yangtze River in Chongqing has been restored through comprehensive measures such as promoting the Yangtze River ecological environment protection project, planting trees and implementing the ecological greening of the illegal wharf on the Yangtze River. The picture shows a scene of Wushan County, Chongqing. Xinhua News Agency reporter Liu Yushe

　　In January 2016, General Secretary of the Supreme Leader pointed out during his investigation in Chongqing that protecting the Three Gorges reservoir area and the mother river of the Yangtze River is related to the long-term development of Chongqing and the overall development of the country. On April 26, 2018, General Secretary of the Supreme Leader delivered an important speech at the symposium to further promote the development of the Yangtze River Economic Belt, stressing that it is necessary to consider the long-term interests of the Chinese nation, put the restoration of the Yangtze River ecological environment in an overwhelming position, and strive to build the Yangtze River Economic Belt into a golden economic belt with more beautiful ecology, smoother traffic, more coordinated economy, more unified market and more scientific mechanism, and explore a new path of ecological priority and green development. The broad masses of cadres and masses in Chongqing thoroughly study and implement the important strategic thinking of the Supreme Leader General Secretary on promoting the development of the Yangtze River Economic Belt, strengthen the upstream consciousness, shoulder the upstream responsibility, speed up the construction of inland open highlands and beautiful places, strive to promote high-quality development and create high-quality life, and fully implement the general secretary’s earnest entrustment on the land of Chongqing.

　　"It is difficult to write about the mountains on both sides of Qutang." The famous sentences written by Zhang Wentao, a poet in Qing Dynasty, tell the fact that the beautiful scenery along the Yangtze River is hard to describe and the wonders are hard to describe. On the coastline of the Yangtze River in Chongqing in May, the first word that comes to mind when people write is "green"; The first word that comes to mind is "returning to green". Re-greening the Three Gorges and the banks of the Yangtze River is exactly what Chongqing wrote to build an ecological Yangtze River and paint the Three Gorges in poetry. Returning to the "green" of the river bank, each kind makes people taste a unique taste.

　　Nearly 700 kilometers of coastline is fragrant with flowers and fruits.

　　Some are green, and the green is sweet.

　　Nearly 700 kilometers of the Yangtze River in Chongqing has built a continuous high-quality fruit base. Citrus in Zhongxian, loquat in Yunyang, grapefruit in Longevity and Liangping, navel orange in Fengjie and crisp plum in Wushan, some are refreshing and pleasant, and some are as sweet as honey. Each flavor tells its own story.

　　Zhongxian County is the core area of citrus in Chongqing and the national citrus demonstration area. More than 200,000 people in the county are employed in the citrus industry chain. Of the 35 acres of standardized citrus orchards that have been built, 220,000 acres have become a unique citrus ecological corridor along the Yangtze River, making the forest coverage rate on both sides of the Yangtze River in Zhongxian County reach 70%. More than 200,000 mu of barren-tolerant crisp plum trees in Wushan County have turned barren hills into flower and fruit mountains. Every year, when plum blossoms bloom in the Spring Festival, both sides of the Yangtze River will become Li Huahai all over the mountains. Flower viewing festivals and picking festivals held by various districts and counties for each kind of fruit can attract hundreds of thousands or even millions of tourists every time, which has become a new highlight of rural tourism.

　　Hundreds of square kilometers of water-level fluctuation zone become a river on Lin Ze.

　　Some are green, and others are persistent.

　　The water storage period of the Three Gorges Reservoir is from September every year to March the following year, and the water level is as high as 175 meters. After entering March, the storage capacity will be vacated before the flood season, when the water level will drop to about 145 meters. Between the high water level and the low water level, a fluctuating zone with a maximum drop of more than 30 meters and a total area of more than 340 square kilometers has been formed in the Three Gorges reservoir area. The water-level fluctuation zone loses more than 100 million tons of sediment every year. How to control the water-level fluctuation zone is a world-class problem.

　　In recent years, all districts and counties in Chongqing, located in the Three Gorges reservoir area, have explored their own unique management modes of water-level fluctuation zone: fengjie county has implemented wetland forest, ecological agriculture and wetland ecological reconstruction projects in water-level fluctuation zone, and implemented ecological management or ecological wetland projects in water-level fluctuation zones such as Baidicheng, Caotang Lake and Kangle Lake; The planned total area of Huanghua Island National Wetland Park in Zhongxian County is 1,400 hectares, including 637 hectares of natural wetlands, 179 hectares of water below 145 meters, and 584 hectares of river bank highlands above the water level fluctuation zone. Experts in agriculture, forestry, environment, meteorology and other aspects of the country believe that the management of the fluctuating zone in the Three Gorges reservoir area is of great significance for protecting the ecological environment, managing mountains, water and poverty.

　　The former director of the Forestry Institute of Wanzhou District Forestry Bureau and the senior forestry engineer let the team persistently find and screen the suitable plants in the water-level fluctuation zone. After 8 years of immersion test, they found that Chinese fir not only grows fast, has fewer pests and diseases, but also is resistant to flooding in winter and drought in summer. In 2012, Wanzhou Forestry Bureau built about 500 mu of experimental demonstration forest within the range of 165-175 meters in the water-level fluctuation zone, and then gradually popularized and planted 1,000 mu, turning the 40-kilometer-long water-level fluctuation zone into a special green ecological corridor and a spectacular aquatic forest along the river.

　　Multi-plant symbiosis on 175 meters water level line

　　Some are green, and the green is meticulous.

　　The ecological protection of the Three Gorges reservoir area sometimes requires the effort of embroidery needle.

　　Yunyang County, bordering Wanzhou, has three municipal forest parks, one municipal nature reserve and two county-level nature reserves, and is one of the seven major forest resources counties in Chongqing. The Huolong Community in Panlong Street, which looks across the river from Yunyang New County, is the planning and construction area of the ecological barrier demonstration section in Yunyang County. In this area, the ecological protection zone within 100 meters above the 175-meter water level of the Three Gorges Reservoir is subdivided into three belts, and tree species are matched according to the requirements of non-functional areas. In Linjiang, a reed belt with a width of 2 meters is planted in the first belt, and a kind of bamboo belt with a width of 3-5 meters is planted in the second belt. In the third belt, evergreen and deciduous leaves, needles and broad leaves, and green and color are mixed to highlight the landscape effect. More than 100 meters above the 175-meter water level line is an eco-economic forest belt, where citrus, grapes, longan and other fruit trees are planted, and other native tree species are planted in the barren hills on the ridge. The ecological protection forest belt cultivated in this way has strong water conservation ability, good soil and water conservation effect and obvious air purification effect, and also drives the annual per capita income of the whole community to increase by more than 2,000 yuan.

　　More than 100 illegal docks turned into green spaces.

　　Some are green, and others are determined.

　　Due to historical reasons and various interests, a large number of illegal docks have been formed in the main stream of the Yangtze River and its tributaries. These docks illegally occupy shoreline resources, destroying the coastal ecological environment and the normal shipping order along the river, and illegal sand mining activities have been repeatedly banned. There are 118 illegal docks in Chongqing, distributed in 17 districts and counties along the main stream and tributaries of the Yangtze River. At present, 108 green buildings have been closed and 10 buildings have been upgraded.

　　The growth and development of green logo can guide rational and wise people. Two sand and gravel processing plants near Luogongzi Wharf in Yuejin Village, dadukou district, disappeared in mid-May. The original site of the processing plant has become a large open and flat green space. Liu Chongyuan, deputy secretary of the Street Party Working Committee, said that the whole district is carrying out greening renovation of the sand and gravel factory along the Yangtze River. After renovation, Luogongzi Wharf will also plant more than 200 trees of pueraria lobata, sow more than 20 tons of Ophiopogon japonicus and more than 2 tons of grass seeds, and turn the wharf into a public hydrophilic park with "clear water, smooth flow, green shore and beautiful scenery".

　　At almost the same time, 40 illegal catering vessels in Jiangbei District were rectified and dismantled. These illegal catering vessels without a qualified sewage system often discharge garbage directly into the river, causing serious pollution to the waters. As the earliest catering vessels existed more than 20 years ago, and there are problems such as overlapping functions in management, how to deal with these illegal catering vessels has always been a "long-standing problem" in Chongqing’s environmental governance. In order to "jointly protect", Jiangbei District Committee issued subsidies and incentives to encourage and guide the owners of catering vessels to abandon their ships and land for other jobs, and finally completely solved the problem of direct pollution of the Yangtze River and Jialing River by catering vessels within their jurisdiction. According to the newly formulated waterfront planning, Beibin Road in Jiangbei District will be transformed into a riverside park, a viewing platform, a high-standard humanistic waterfront leisure area and a riverside art gallery.

　　The "big construction site" in the Three Gorges reservoir area has become a "big park"

　　Some are green, and the pain is sweet.

　　He Xianhua, who lives near Tianxianhu Square in Wanzhou District, likes to fly kites in the square with his family, take a walk along binjiang road or go to nanshan park to bask in the sun in his spare time. In the past, He Xianhua could see the black smoke from the factory at home, and he could smell the pungent smell of burning coal and lampblack in some small restaurants facing the street. In order to let the children breathe more fresh air, he takes them to his hometown in the country every weekend. In recent years, after Wanzhou stepped up efforts to control air pollution, the gray days gradually turned blue and the dirty air gradually became sweet. In recent years, there are more green plants in Wanzhou city, and egrets will patronize the square from time to time. This makes He Xianhua feel particularly gratified. He said: "I have lived here since I was a child and worked here when I grew up. I have a deep feeling for every change in the environment. "

　　"Look at the river with your pillow, and do whatever you want. Wulixi, Yunshan, Three Gorges, stay with me in Yuzhou. " In May, the temperature in the Chongqing reservoir area of the Three Gorges of the Yangtze River has entered summer, but there is still a poetic feeling of "green hills like the east of Daiyuan village, green and long streams with catkins" among the mountains and waters, attracting many tourists to visit. Today, 16 years after the Three Gorges Reservoir was officially impounded, it has changed from the original resettlement site to a beautiful park. Chongqing has set an ecological red line of 63 million mu of forest land, 56 million mu of forest and 3.1 million mu of wetland for itself. This is also the premise and bottom line for Chongqing to build an ecological barrier in the upper reaches of the Yangtze River and strengthen the construction of a beautiful and beautiful place. The essence and essence of "clear water in one river, green hills on both sides of the river, red leaves in the Three Gorges, clouds and rain in all seasons, ancient towns with thousands of years of civilization", beautiful canyon clear water, gorgeous red leaves in Jiangshan and charming clouds and rain in Wushan are all green in the Three Gorges.

　　 (Reporter Zhang Guosheng)

　　CCTV News:Bo Yuan Tie, Wu Niu Tu, Wang Chu Zhi Tomb Relief Stone Carving, Longmen Grottoes Stone Carving Buddha Statue, Qin Cemetery Gold Decorative Piece, Pan Fang, Yuanmingyuan Bronze Tiger, Zeng Boke Father Bronze Assembler … … Behind every cultural relic, there is a tortuous return story. On September 17th, the Ministry of Culture and Tourism and National Cultural Heritage Administration hosted the "Road to Return — — The exhibition on the return of lost cultural relics in the 70th anniversary of the founding of New China opened at the National Museum of China.

　　Liu Yuzhu, director of the National Cultural Heritage Administration, pointed out in his speech that the cultural relics lost overseas in China are an inseparable part of China’s cultural heritage, and the return of cultural relics is closely related to the rise and fall of the country’s chaos, which closely touches the hearts of Chinese people. The Party and the government attach great importance to the rescue and protection of lost cultural relics. Since 1949, more than 300 batches and 150,000 pieces of lost overseas cultural relics in China have been successfully returned through law enforcement cooperation, judicial proceedings, negotiated donation and rescue collection.

　　In this exhibition, 25 representative cases of cultural relics’ return were carefully selected, and more than 600 cultural relics from 12 provinces and cities and 18 cultural and art institutions were mobilized to participate in the exhibition, and the tortuous course and wonderful stories of cultural relics’ return were excavated and told. Let’s enjoy the magnificent 70-year return of cultural relics in the return story.

The bronze statue of the rabbit in Yuanmingyuan, donated by Mr. Francois Pinault in the Qing Dynasty, is in the National Museum of China.

　　In the mid-19th century, the great powers’ strong ships and strong guns shattered the dream of going to China in the late Qing Dynasty. In 1860, the British and French allied forces captured Beijing, the Garden of Ten Thousand Gardens was set on fire, and precious cultural relics were swept west. A treasure that has lost its dignity and glory records an embarrassing past in the drift from place to place, and also affects the heartstrings of thousands of people.

　　Since the 1980s, the lost cultural relics in China, including the animal heads of Yuanmingyuan, have appeared overseas one after another. International auction companies have repeatedly made profits at high prices, and Chinese people have been strongly indignant and condemned. International public opinion has paid extensive attention to it, and the return of cultural relics is facing many obstacles. The China Municipal Government has always been determined to promote the return of cultural relics, from the state-owned enterprises bidding for the heads of cattle, tigers and monkeys, to the donation of Chinese businessmen for the heads of horses and pigs, and then to the return of foreign friends for the heads of rats and rabbits. The animal heads in Yuanmingyuan have traveled from scattered stars to reunited, which is exactly a road to the return of cultural relics lost in China.

　　The bronze statue of the animal head in Yuanmingyuan was originally a component of the fountain of the zodiac in Haiyan Hall of Yuanmingyuan. In 1860, the British and French allied forces looted Yuanmingyuan and lost it overseas. The animal head was designed by western painters during the reign of Emperor Qianlong of Qing Dynasty, and made by artisans in China court, combining the cultural characteristics of the East and the West. The animal head is lifelike in shape and delicate in performance, showing a high technological level.

　The word "Liao" in volumes 5248 and 5249 of Yongle Dadian was returned by the former Soviet government in 1954 in the Ming Dynasty and kept by the National Library of China.

　　Yongle Dadian was written in Yongle period of Ming Dynasty, which was the first encyclopedic document integration in ancient China, and a set of copies was copied in Jiajing period of Ming Dynasty. Sadly, after the rise and fall of political power and the catastrophe of war, the original Yongle Dadian has disappeared, and a few surviving copies are also lost.

　　During Eight-Nation Alliance’s invasion of China in 1900, German soldiers snatched three volumes of Yongle Dadian from the Imperial Academy in Beijing, and then collected them in the library of Leipzig University in Germany. On December 11th, 1955, the former GDR Chancellor Grotewohl returned the three volumes of Yongle Dadian and ten Boxer flags to China.

　Wang Xianzhi’s Mid-Autumn Festival Post (copy), Jin Dynasty, the original is in the Palace Museum. (Because the Mid-Autumn Post and Han Xizai’s Night Banquet are currently in the dormant period of cultural relics, this exhibition shows replicas. )

　　Mid-Autumn Post, Bo Yuan Post, and the Post of Quick Snow in the National Palace Museum in Taipei are collectively called "Three Wishes" by Qianlong. At the end of the Qing Dynasty, the Mid-Autumn Festival and Boyuan were taken out of the Forbidden City by Puyi, and then changed hands several times and moved to Hong Kong. In October, 1951, Zheng Zhenduo learned that "Erxi" was about to be sold by inquiry, and immediately started the rescue of cultural relics with the assistance of Xu Senyu, Hu Huichun and Xu Bojiao. Wang Yeqiu, then deputy director of the Cultural Relics Bureau of the Ministry of Culture, was ordered to negotiate with Xu Senyu, director of the Shanghai Cultural Management Committee, and Ma Heng, president of the Palace Museum, and finally successfully bought back Erxi and handed it over to the Palace Museum for collection, ending the decades-long drift of two national treasures.

　Yang Quan donated cultural relics.

　　Yang Quan, a native of Guangdong, moved to Hong Kong with his father when he was a teenager. He was deeply saddened by the loss of cultural relics in the motherland and determined to do his best to protect Chinese cultural relics. During the Japanese occupation of Hong Kong, Yang Quan went through all kinds of difficulties to save the collection of cultural relics from being poisoned. Before liberation, he witnessed the situation that China cultural relics were stolen and sold by imperialists, warlords, bureaucrats and illegal profiteers in Hongkong, and he was heartbroken and longed for the prosperity of the motherland. In 1946, Yang Quan told Guo Moruo that he would donate his personal cultural relics unconditionally to the "trustworthy government". Therefore, after the founding of New China, he deeply realized that "the motherland became strong after liberation, but also because the government paid attention to the preservation, collation and research of cultural relics", and he decided to donate all cultural relics to the new China government.

　　From 1959 to 1964, Mr. Yang Quan overcame all kinds of difficulties and transported more than 5,000 pieces (sets) of cultural relics collected by him to the mainland in eight batches and donated them to the country. Mr. Yang Quan’s lifelong wish has been fulfilled. This is the largest cultural relic donation accepted by our government at the beginning of the founding of New China.

　Copper crane, collected in the management office of the Summer Palace in Beijing in Qing Dynasty.

　Baoyunge copper window, collected in the management office of Beijing Summer Palace in Qing Dynasty.

　　The Baoyunge Copper Hall in the Summer Palace was built in Qianlong for twenty years. All the components of the copper hall, such as beams, arches, rafters and plaques, were cast by the traditional "wax pulling method" and "sand breaking method" in China. In 1900, the Summer Palace was looted by Eight-Nation Alliance, and ten bronze windows in the bronze hall of Baoyunge were lost to France.

　　Around 1992, maurice greene Berg, the chairman of the American Industrial and Commercial Insurance Company, accidentally learned the whereabouts of ten copper windows, bought these copper windows in July 1993 with a large sum of money, and returned them to China for free. On December 3, 1993, the restoration and installation of the bronze window was completed in the Summer Palace, and the bronze window was finally returned to Baoyun Pavilion. The bronze temple stands tall, making future generations want to see the longevity scenery and beautiful scenery of that year.

　　In 1975, Dr. Ambrose Harding of the United Kingdom gave back the Qing Dynasty bronze cranes and other cultural relics looted by the British and French allied forces from Qingyi Garden (the predecessor of the Summer Palace) in 1860.

　　All the components of Baoyunge are cast by the traditional "wax-pulling method" and "sand-breaking method" in China, and then they are continuously cast together to form an integral bronze temple, which embodies the outstanding achievements of investment casting technology in China and has high scientific value. The style of the bronze crane is realistic, the shape is plump and strong, which means auspiciousness. The return of cultural relics in the Summer Palace is of great significance for restoring the integrity and authenticity of the Summer Palace.

　　The bronze windows and cranes in the Summer Palace are lost cultural relics that returned earlier through donations from international friends.

　The Buddha’s head in Gaoshu niche, returned by Chinese Americans in the Northern Wei Dynasty, collected by Longmen Grottoes Research Institute.

　Luohan statue in Kanjing Temple, Tang Dynasty, returned by Canadian government, collected by Longmen Grottoes Research Institute.

　　At the beginning of the 20th century, Longmen Grottoes, the artistic treasure of ancient Buddhist sculpture in China, was severely damaged and chiseled, and countless exquisite statues were lost overseas. Guyang Cave, Lianhua Cave, Huoding Cave, Wanfo Cave, Kanjing Temple, etc. were particularly damaged, and the Buddha sculptures in many grottoes were "beheaded" for a long time. Among them, the Kanjing Temple relief Luohan statue was stolen in 1930s, and it appeared in European and American auctions, and was later donated to the National Gallery of Canada. In April 2001, after friendly consultations between the two sides, the National Gallery of Canada decided to return the cultural relics to China free of charge after fully understanding the background and great historical and cultural value of the theft of the relief Luohan statue. This is the first time that the Chinese government has prompted important foreign cultural relics collection institutions to retreat and return the lost cultural relics.

　　The return of Kanjing Temple’s reliefs of Lohan opened the prelude to the return of the stolen Buddha statues in Longmen Grottoes. From 2004 to 2005, after rigorous expert argumentation and research by Longmen Grottoes Research Institute, National Cultural Heritage Administration rescued and collected seven Buddhist statues in Longmen Grottoes, including the head of Sakyamuni Buddha in the Northern Wei Dynasty and the head of Guanyin Bodhisattva in Huoding Cave, and held a celebration of the return of Longmen Grottoes lost overseas in October 2005.

　Bronze dish Fang Qian, Shang Dynasty, Hunan Provincial Museum.

　　In 1919, Qijiahe, Taoyuan County, Hunan Province, unearthed a large, majestic and exquisite bronze square mound, which was called "dish square mound" because of its inscription. This Qian is a representative work of bronze wares in China in the late Shang Dynasty and early Western Zhou Dynasty.　

　　At that time, the land of China was devastated and its civilization was not prosperous. Unfortunately, the body was exiled overseas, passed on to antique dealers in several countries, and drifted to foreign countries in Asia, America and Europe. The lid has been kept in private hands in China, and it was nationalized in 1952. In 1956, the Hunan Provincial Cultural Management Committee handed it over to the Hunan Provincial Museum for collection. In the early 1990s, Japanese collectors interacted with provincial museums several times, and both sides tried to combine the artifacts in their own ways, but they failed.

　　In 2013, the dish square reappeared in the international auction market, and will be officially auctioned in the United States in March 2014. In order to prevent cultural relics from being displaced overseas, under the coordination of National Cultural Heritage Administration and with the support of Hunan Provincial Party Committee and Government, Hunan Province sent a delegation to new york to discuss the return of cultural relics. In the end, with the goodwill of all parties, the original auction plan was cancelled and the vessel was returned to the embrace of the motherland. On June 28, 2014, all sides of the dish day bowed their heads and entered the Hunan Provincial Museum, and finally completed this century-long road of return.

　Dengyu Stone Tower, Tang Dynasty, Shanxi Museum.

　　In 1998, the stone pagoda in Dengyu was stolen and moved to Taiwan Province, China. In 2015, it was donated to Zhongtai Temple by private collectors. The abbot, the founder of the temple, felt that the elder was willing to donate the tower back after learning that it came from Shanxi. National Cultural Heritage Administration attached great importance to the relevant information, and immediately organized an expert group to carry out investigation and verification, on-site evidence collection, and coordinated the Shanxi Provincial Bureau of Cultural Relics and Zhongtai Temple to jointly carry out historical records research, identification and comparison, and finally confirmed that the stone pagoda in Zhongtai Temple was indeed the stolen tower of Dengyu Stone Pagoda. In August 2016, Shanxi Museum and Zhongtai Temple signed the Agreement on Donating Cultural Relics. In January 2017, the tower arrived in Shanxi Museum and finally returned to his hometown after 20 years of disobedience.

　　Dengyu Stone Pagoda, located in Dengyu Village, Yushe County, Shanxi Province, is a four-faced Buddha statue tower carved with stones and painted in Tang Dynasty, which consists of four parts: base, tower body, tower eaves and tower brake. The stone pagoda is a masterpiece of Buddhist stone carving art in the prosperous Tang Dynasty, with its solemn and simple shape and rich body-building in high relief.

　　Taiwan Province and the mainland belong to the same China, and the two sides of the strait are of the same ancestry and culture. The tower safely returned to its hometown, drawing a satisfactory end to the anxiety of leaving home for many years. This is another landmark event that remains in the hearts of people on both sides of the strait and is recorded in the history of cross-strait cultural exchanges.

　Bronze Tiger Gun, Western Zhou Dynasty, China National Museum.

　　Bronze Tiger Gun is a cultural relic in the late Western Zhou Dynasty, which was originally collected in Yuanmingyuan. In 1860, the British and French allied forces looted Yuanmingyuan, among which the bronze tiger was taken away by Harry Evans, a British naval officer, and brought back to Britain.

　　In March, 2018, the news that the tigers of Yuanmingyuan will be auctioned in Britain triggered strong repercussions from all walks of life in China, deeply affecting the heartstrings of domestic people and patriotic overseas Chinese. Knowing that Tiger Gun was backward, National Cultural Heritage Administration immediately carried out information collection, consultation and negotiation, coordination and linkage, publicity and guidance, and comprehensively used various channels such as diplomacy, commerce and public opinion to actively promote the return of bronze Tiger Gun.

　　At the end of April, 2018, the overseas buyers of the bronze Tiger Gun expressed their willingness to donate cultural relics to National Cultural Heritage Administration, China. On September 21, 2018, the delegation of National Cultural Heritage Administration held a donation reception ceremony for the tiger sole in the British Embassy of China. In December, 2018, the bronze tiger tiger was officially admitted to the National Museum of China.

　Zeng Boke’s father bronze assembly, early Spring and Autumn Period.

　　At the beginning of March 2019, National Cultural Heritage Administration learned that a Japanese auction house planned to auction the bronze assembly of Zeng Boke’s father, which was suspected to have been lost in China, and immediately organized a team of experts to study the bronze assembly, confirming that it was a cultural relic illegally left the country after the tomb of Zeng Guo in Hubei Province was recently stolen, and then jointly pursued recourse with the public security department through criminal and diplomatic channels.

　　On March 9, National Cultural Heritage Administration officially sent a note to the Japanese Embassy in China, demanding that the Japanese government return the cultural relics lost in China in accordance with relevant international conventions. On the same day, Japanese auction companies publicly announced that they would withdraw the bronze assembly. Subsequently, representatives of the Chinese and Japanese governments jointly met with representatives of auction enterprises, and the public security organs intensively promoted the investigation of cultural relics smuggling crimes, which eventually led to the entrusting party of bronze assembly auction handing over cultural relics to the state free of charge.

　　The bronze assembly of Zeng Boke’s father was cast by Ke Fu, a high-ranking aristocrat in the State of Zeng in the Spring and Autumn Period. It includes eight pieces in six categories, including ding, GUI, pot, pan, pheasant and cup. It is rich in categories, exquisitely cast and well preserved. Each bronze has an inscription, totaling 330 words, which contains rich historical and cultural information. The artifacts of "Father Zeng Boke" have not been found in archaeological discoveries at present, which is of great academic value for studying the history and culture of the Spring and Autumn Period, the patriarchal clan system of Zeng State, and the dating and casting technology of bronzes.

　　At that time, every cultural relic was burdened with the weight of the times and the sorrow of the nation; Returning today, what each cultural relic has written is the road to revival and the dream of China.

　　It is reported that the exhibition will last until the middle and late November.

Beef is rich in protein and creatine. Its nutritional composition is closer to human needs than pork.

It is about to enter summer, and the hot weather makes many people feel that they should eat less beef, thinking that beef is a patent in autumn and winter.

In fact, this is a misunderstanding of beef in the traditional diet concept. The weather in summer is hot and consumes a lot, especially for people who do manual labor or do more exercise and fitness. Eating beef can provide them with high-quality energy needed by muscles and cells.

Eating beef in summer gets angry?

Beef, like other animal proteins, can be eaten in all seasons. It won’t make you "get angry" by itself. The cause of getting angry lies in the cooking methods and ingredients, such as star anise, pepper and pepper.

If you want to avoid getting angry when eating beef, you can choose the method of "cold and hot collocation". When cooking beef, add some cool vegetables and stew them together. Such as carrots, potatoes, mushrooms, cabbage and so on.

In ancient times, it was said that beef is the second largest meat food in China, second only to pork, and enjoys the reputation of "the favorite among the meat".

I believe many people still like to eat beef, so how do you clean the beef you bought? Many people directly rinse the beef with clear water and then start slicing or blanching.

In fact, the more boiled the beef, the dirtier it is! There are a lot of blood clots in beef. After blanching, the blood clots are all condensed in beef and can’t get out at all. In this way, the smell of beef must be very heavy!

Teach you a trick to clean beef correctly:

Tips for cleaning beef

/cleaning/

Step 1: Put the bought beef under the tap and rinse it with running water. First, rinse off some bacteria and dirt on the beef surface. Then prepare a bowl or basin and pour a proper amount of warm water into it.

Note: Washing any meat with warm water not exceeding 50 degrees can wash away the blood of meat products.

Step 2: The next step is very important, which is to add a proper amount of salt and a spoonful of white vinegar to warm water.

White vinegar and salt have bactericidal effect, and warm water can soak blood out of beef. Rub the beef slowly with your hands.

At this time, we will find that the dirty things fled out actively ~ blood foam and blood clots all floated on the water.

Step 3: Take out the beef, then pour in the right amount of water and wash it several times. The beef washed in this way is tasteless and very clean.

It is also very important to blanch the beef after cleaning.

/drowning/

Practice: put the cleaned beef into a cold water pot. Remember, it must be a cold water pot.

Then add an appropriate amount of onion, ginger and garlic to the pot, cover the pot and simmer for about 4 minutes. At this time, we will find a layer of dirty things floating on the water.

Skim off these dirty things, then fish out the beef, put it in clean water and rinse it again.

Doing so can make beef cleaner. Moreover, we can kill two birds with one stone by adding onion, ginger and garlic to the pot, which can remove some fishy smell of beef itself.

Through these two steps, the treated beef is very clean and has no fishy smell at all. Whether we use it to braise in soy sauce or make soup, the taste will be much better than that of beef processed by ordinary methods before.

Especially when we are cooking soup, we will find that the meat quality of beef will be more tender and firm, and it will be more delicious.

There is still a problem with eating beef-the stew is not bad!

You can’t even chew ~ ~

Stewing time is too short to cook.

It’s easy to get old after a long time

It’s really delicious beef, but it’s not easy to cook!

How can beef be stewed?

First, choose the meat to make it soft and tender.

Choose fat and thin meat.

Whether it is frying or stewing, choosing the fat and thin one will be more tender than the pure thin one.

It’s better to try beef rib stew, cut into hob pieces, rich in oil, and stewed tender tendons in it, which is rich in taste. You can also choose bovine tendon, the anterior tendon is more tender and the posterior tendon is good. Cutting hob blocks or small pieces will do. Cattle tendon rots quickly, and usually it will be cooked just right after stewing for one and a half hours.

Choosing the right part is the key.

Choosing the right part is the key, and it depends on your cooking method. Fresh meat is suitable for frying and scalding hot pot, and beef brisket, beef tendon and tail are suitable for stewing.

Second, the prelude to cooking, there are doorways to deal with beef

The fibers of the meat are interrupted first.

Cut off the fiber directly with a pine needle or a pine hammer, and then fry, fry or stew it.

You can also use the back of the Chinese kitchen knife to pat the meat or the side of the knife and photograph the fascia of the meat spreading.

Vertical texture meat block

Pay attention to the meat when you cut it. Don’t cut it along the grain, but cut it perpendicular to the grain.

Cured meat has a doorway.

Marinate the beef with baking soda powder and starch for more than half an hour, and the beef will be tender.

When pickling, you must add blending oil first, and you can’t add salt. The salt will dehydrate, and it will be old no matter how it is cooked!

You can also squeeze some lemon juice when pickling. Fruit acid can destroy the tissue of meat.

Third, the small coup when stewing beef

Use tea skillfully, only add boiling water.

If it is stewed, wrap a pinch of tea with gauze, which can enhance the flavor and make the beef tender faster. Add enough water at one time. If water must be added halfway, add boiling water instead of cold water.

Honey or red wine proteolytic protein

When stewing, put some honey or red wine, both of which contain enzymes and proteases that decompose animal proteins, which can make the meat soft, but honey will be decomposed before the broth is scalded.

Sugar and vinegar destroy the cell structure.

Sugar and vinegar can destroy the cellular structure of beef and make its meat soft and rotten. You can also simply put one or two hawthorn instead, and the effect is the same. Because hawthorn contains a certain amount of lipase and maslinic acid, it can promote lipolysis and improve the activity of proteolytic enzymes, and the main components of meat are protein and fat.

Use beer instead of water.

Using beer instead of water, the approximate ratio is two Jin of beef and a bottle of beer. Even beef tendon can be stewed in two hours!

Add soybean sauce and tomatoes, soft and delicious.

When you stew beef, add some soybean sauce and stew it in a pressure cooker for 20 minutes. After coming out, the soup is particularly good and soft.

Beef stew with tomatoes is king. If you don’t want tomatoes to dominate, just add one or half. Beef rots quickly and tastes better.

These are some tips about stewing beef.

Read the original text

　　In recent years, I have often met some friends who sent me some pictures of potted plants, saying that I suddenly saw on the Internet that they were carcinogenic plants, but I happened to have them at home. I am very worried. Do you want to throw them away? Some micro-friends even sent links to articles, such as "Don’t leave these 52 kinds of cancer-causing plants at home", "Please stay away from these cancer-causing plants" and "80 kinds of common toxic or cancer-causing plants" … What’s more, it is said that a couple of flower farmers who have been planting flowers for a long time in Foshan City have suffered from nasopharyngeal carcinoma.

　　For a time, flower friends talked about the change of colors, "expelling the culprit of cancer" and "cleaning up the door", which meant that these plants were wiped out. In fact, is this really the case?

　　The statement comes from a paper nearly 30 years ago.

　　It is understood that this statement originated from a paper "Screening of Chinese Herbs and Plants Inducing Early Antigen Expression of Epstein—Barr Virus" by Academician Ceng Yi from Institute of Virology, Chinese Academy of Preventive Sciences. According to the article, "1693 species of plants (Raji cells with EB virus as experimental objects) were screened, and 52 of them were found to have the effect of inducing the early antigen expression of EB virus". And these 52 plants happen to be the "52 carcinogenic plants" transmitted by the Internet.

　　This paper was first published in 1992, almost 30 years later. The news of cancer-causing plants still appears in tabloids, Weibo and friends circle from time to time, and is often mentioned by people. Let the flower growers tread on thin ice, and create many unjust, false and wrong cases of flowers and plants.

　　Epstein-Barr virus is a virus isolated from people with lymphoma. 90%-95% people have been infected by this virus, but most of the time it will not affect human health. Only under the external stimulation, EB virus will suddenly "wake up" and start to replicate in large numbers, which will make the signal pathway controlling normal differentiation and proliferation in cells abnormal, thus causing cancer. Horribly, the activity of EB virus will promote other carcinogenic viruses (such as SV40 virus) to start activities.

　　It is found that the secondary metabolites produced by some plants can activate EB virus, make it wake up and become an active replication state, so these secondary metabolites are called "cancer-promoting" substances. For example, croton oil extracted from croton seeds has a strong ability to induce early antigens of EB virus.

　　However, it can be seen from the above description that plants themselves do not produce EB virus, and even some cancer-promoting substances released into the soil through fallen leaves or roots are only accomplices, not masterminds, in causing cancer. Therefore, the statement that these plants "contain carcinogenic viruses" on the Internet is groundless and a misunderstanding of scientific papers.

　　Plants containing cancer-promoting substances can still be domesticated.

　　Can 52 kinds of plants containing cancer-promoting substances detected by academicians still be raised in their own homes? This is probably what all flower lovers are eager to know.

　　The answer is, of course, yes. These plants, if you don’t eat them and maintain them normally at home, will not cause harm to the human body.

　　If these chemical cancer-promoting substances in plants are taken out and identified, they are just secondary metabolites of plants, and they are a large number of chemical synthetic products with complex structures that are not directly involved in plant growth and development. Plants use these compounds to improve the body’s ability to resist the invasion of the external environment, such as driving away hateful pests, transmitting useful information between plants, dealing with diseases and various unfavorable factors in the surrounding environment, and attracting "matchmakers" or "bodyguards" who help themselves pollinate …

　　Human beings are no strangers to the secondary metabolic "products" of plants, such as rubber, spices, essential oils and so on. The content of these secondary products in plants is not high. Most of the time, they stay quietly in plants and are released only when plants are in danger or their limbs are damaged. Only when these products enter the intruder’s body will they have the effect of poisoning or driving away; For flower growers, only when they enter the human body can they induce cancer.

　　Emphasize that it only induces cancer and promotes cancer, but it is not carcinogenic.

　　Some people may ask, I usually don’t eat potted flowers or move potted flowers, so will the secondary metabolites in these potted flowers float in the room in the form of gas, thus promoting cancer?

　　"It’s all hooliganism to talk about toxicity regardless of dosage". Generally speaking, the secondary substances in plant defense system have large molecular weight and poor volatility. Unlike esters and alkanes which are easy to volatilize in plants, they are mostly water-soluble secondary substances, and almost lose their volatilization ability in plants with high water content. The dose that can be volatilized into indoor air is very small, and they pose a cancer threat to people, even less than smoking a cigarette and breathing automobile exhaust.

　　In the book "Volatile Gases from Plants and Human Health and Safety", the volatile components of Rosa davurica, one of the "52 Carcinogenic Plants", were detected. The results showed that no cancer-promoting components were detected in its volatile components. Therefore, flower friends only need to know the properties of these plants and the characteristics of toxins in their bodies, and they can coexist peacefully with these plants without any burden without touching or eating them.

　　Three so-called "carcinogenic plants"

　　As long as you don’t eat, you can rest assured.

　　Let’s find out three so-called "cancer-causing plants" that are common indoors in northern China for the time being, and here we will break them down one by one.

　　dripping guanyin

　　Drip Guanyin is very suitable for keeping indoors. Staggered leaves, shaped like cattail fans, protrude from the base of brown leaves wrapped in layers, giving off a shiny luster. Drip Guanyin is resistant to shade, and its huge leaf surface can absorb dust and toxic gases in the air. Watered enough water the night before, and got up the next day to observe the leaves. There must be glittering and translucent "water drops" hanging on the tip of the leaves. That is, use toilet paper to absorb the water droplets on the tip of the leaf, and in a short time, a "pearl" will be hung on this part.

　　This is because the dripping Guanyin, which originated from the bottom of the tropical rain forest, can "sweat" like a human being. When it feels hot and humid, and there is too much water in its body, it will excrete the water together with the toxin alkali secreted by pests through its own catheter, and condense it into "water droplets" at the tip of the leaf. This water drop is actually the secret weapon of dripping Guanyin. Small insects that come here for food will be doomed if they drink this honey dew as dew or accidentally touch it. Drinking "honey dew" will make small animals’ mouths red and swollen or suffocate because of heart paralysis; Once the honey dew touches the skin, the skin immediately itches and swells; If the eyes touch the "water drops", it will cause severe conjunctivitis and even blindness … People accidentally touch it, and it is the same symptom. It is also reported that some people saw that the massive stem of Drip Guanyin was very white, a bit like a potato and watery, so they couldn’t help licking it and wanted to taste the juice inside. I didn’t expect this lick to bring disaster-swollen lips, sore throat and numb tongue.

　　In fact, in plants, it is very common that the roots and leaves of plants contain toxins. The dripping Guanyin belongs to Araceae, and most of the plants in this family are poisonous, such as tortoise-back bamboo, evergreen and green radish.

　　crown of thorns

　　Red flowers, rising slowly from the hard and pointed cone thorns, are delicate, charming and graceful. During the Spring Festival, the blooming Rosa davurica will add a lot of spring scenery to the living room, which is also the reason why northerners love Rosa davurica. It is not afraid of drought, waterlogging, shade and sun, and it is very easy to feed.

　　Its vitality is super strong: if you don’t water it for half a year, you won’t get the sun, but you can live in a decent way, and the cute little buds with pink branches will bloom again. Even if you cut a branch and let it lie on the ground, you can grow roots, and green buds will burst out on the branch.

　　Rosa davurica, also known as begonia, is a member of Euphorbia in Euphorbiaceae. Euphorbia plants have a common feature: white milk will be secreted from the wound after the plant is injured. This kind of milk is a diterpenoid compound with special structure, which is toxic. This is also a "sharp weapon" for such plants to protect themselves and prevent pests and diseases from invading during the evolution process. The white milk secreted by the "wound" of Rosa davurica also stimulates human skin and mucous membrane. Eating it by mistake will cause nausea, vomiting, diarrhea and dizziness.

　　iris

　　Iris, which we often say, is not a plant, but a general term for iris plants. Its German Iris, Iris, Iris and Cynthia are all called Iris in principle.

　　Iris plants have bright and beautiful colors. The Latin name iris comes from Greek and is the name of Iriz, the goddess of the rainbow. It can be seen that the colors of iris plants are as colorful as rainbows. It is common to have two or three colors on a flower, which is the eternal darling of horticulture. According to the internet, the rhizome of iris can be used as emetic and cathartic, and can also be used as medicine to treat dizziness and toxic swelling. Eating its flowers, leaves and roots will cause gastrointestinal congestion and severe diarrhea.

　　As can be seen from the above examples, whether these plants cause cancer depends on whether you eat them or want to grow them in flowerpots for viewing. If it is only the latter, you can raise these plants with peace of mind. According to some data, 97% of the 368 kinds of flowers planted at home are beneficial to human health. Of course, we have to emphasize the four basic principles of peaceful coexistence with domestic plants-no matter what flowers are raised at home, don’t import them; Try to avoid zero-distance contact with plant secretions; Wash your hands after handling plants; Open the doors and windows to let the air circulate.

　　Zhongxin. com, Hangzhou, September 29 (Reporter Zhang Yuhuan) On the 29th, the reporter learned from the Zhejiang Meteorological Observatory that according to the latest meteorological data analysis, it is expected that during the National Day holiday this year, Zhejiang Province will be successively affected by typhoon Mina and weak cold air, among which the province will usher in stormy weather from 1 to 2, and the typhoon center may have 14 to 15 winds passing through the sea.

　　The National Day holiday coincides with the growing autumn in Zhejiang. The temperature is generally suitable, but the daily temperature range is large. The average annual temperature in most parts of Zhejiang is 20-22℃, the average precipitation is 15-40 mm, and the average precipitation days are 2-3 days.

　　With the approaching of Typhoon Mina, the 18th this year, the National Day holiday in Zhejiang will also usher in a stronger autumn. On the 29th, the typhoon was strengthened from a tropical storm level to a strong tropical storm level. It is expected to pass the northeast of Taiwan Province Island on the evening of the 30th, and then gradually turn to the north and move towards the north-central coast of Zhejiang.

　　Influenced by Typhoon Mina, Zhejiang Meteorological Observatory predicted that the wind power in the southern part of the East China Sea will start to increase from the 29th, and there will be 11-13 winds in the East China Sea from the 30th to October 1st, and 14-15 winds in the nearby waters where the typhoon center passes, and the wind power in the coastal waters of Zhejiang Province will gradually increase to 10-12, and 13-14 in some areas. There are also 7-9 winds in some inland areas of Zhejiang Province, and there are heavy rains and heavy rains in eastern Zhejiang and parts of northern Zhejiang.

　　From October 3rd to 4th, Zhejiang Province was dominated by cloudy weather, with the highest daily temperature of 32-34℃ in most areas. From October 5th to 7th in the latter part of the holiday, affected by the weak cold air in the north, there was weak precipitation in some areas of Zhejiang Province, and the temperature dropped slowly. The lowest temperature in the morning of October 7th was 16-19℃.

　　The meteorological department reminded that during the National Day holiday, there were heavy rains and heavy rains in eastern Zhejiang and northern Zhejiang, and there were strong winds at sea. Relevant departments should pay attention to preventing the adverse effects of strong winds at sea on island tourism and maritime traffic. From October 3rd to 7th, the weather conditions in Zhejiang Province are generally favorable for leisure travel, but with the influence of cold air moving eastward and southward, we still need to pay attention to the obvious cooling and weak precipitation process.

Many people ridicule that it is the next generation of network car, which is not expensive to sell and the configuration is OK. The key is that it has low energy consumption and good economy! In fact, Tucki’s previous car energy consumption control was also good, but the latest MONA heard that it was even worse. We are also very curious about the level of power consumption and endurance achievement rate of this car.

Therefore, we have arranged the endurance test of two scenes simultaneously, one is the high-speed road test, and the other is the urban road test. Besides this endurance test, I have been driving this car back and forth for several days, so I can give you a more comprehensive experience.

First of all, the endurance performance, we still follow the test route of previous tests, located in Nanda trunk line. On the test day, the outdoor temperature was about 32 degrees Celsius, the fast-charging pile was fully charged, the kinetic energy recovery was adjusted to the maximum, the driving mode was adjusted to the energy-saving mode, the air conditioner was adjusted to 24 degrees Celsius to circulate the automatic wind, and the subtotal mileage was cleared, and the tire pressure was maintained at about 240kpa.

Nanda trunk line is a relatively long expressway with a speed limit of 80 km/h. After we are fully charged, we basically run around this road. Except for turning around at both ends and waiting at traffic lights, they are basically driving near the speed limit, but in the end, the average speed is about 60km/h, which can better represent the daily commuting power consumption.

The car we got was an entry-level version of the 515 endurance car, but when the endurance reached 0%, it drove 518km. At this time, the achievement rate exceeded expectations, and it ran for another 9 km until the power was limited. The final result was locked at 527km, and the endurance achievement rate was 102%. The meter showed that the power consumption was 9Wh/100km, which showed the last 100 km, but even if it was calculated according to the electricity, the 51.8-degree electricity ran 50 km.

And on the day of the test, my colleagues in Beijing also took a Tucki, 620 model with a long battery life, and they went directly to the high speed, holding up the live broadcast test at a speed of 120km/h, and finally the power consumption per 100 km was 12.6kWh/100km, which was also very low.

And this 515km version of Tucki, I have experienced five days back and forth, and I have also driven violently, and the power consumption is in the early 14kWh/100km. Therefore, if I drive steadily every day, this endurance performance can be achieved by anyone, which is enough to show that the power consumption of MONA M03 in Tucki is superior to that of the trams on the market at present, regardless of the middle and high speed scenes.

It is also the lowest power consumption among the models we are currently testing.

Some netizens think that the price of this car’s low power consumption is weak power. In fact, to be honest, the control of this car is more advantageous for the same price model, and the feelings of the three driving modes are also different. The economy and comfort modes are similar, but the comfort mode will have a little stronger power in the front and back stages, and the sports mode will be full of power from the beginning.

Kinetic energy recovery can be closed and adjustable in three gears. High kinetic energy recovery will nod a little after releasing the throttle, and it needs to be adapted to the body. It is recommended to open it in the middle and low for daily driving to ensure the comfort of the body and improve the battery life.

MONA in Tucki is relatively easy to drive as a whole, and it is not quite the same as Tucki before. In the past, even if the steering wheel was turned to sport mode, the overall feel was still light, and the medium and large SUVs like that were also very light, while MONA’s steering was obviously much tighter, and the switch damping seemed to be tighter.

Chassis can be regarded as the normal level of this level. The former McPherson rear torsion beam is relatively resilient when passing through some speed bumps at low speed, and it is quite satisfactory for filtering fine vibrations. It will feel less comfortable when encountering relatively large ups and downs, but the overall afterlife is still in line with the tonality of this price.

The layout of the whole car is very simple. There is only one screen in the central control area, and there is no instrument. The overall operation logic is more like the old Tesla, and the operating system interface is relatively simple. Fortunately, most operations can be realized by voice, but this voice does not seem to support multiple voice commands. Only 1-2 commands can be completed at a time, but the recognition accuracy is still ok.

Then the automatic parking recognition rate of this car is average, but as long as most parking spaces are recognized, they can basically be listened to well, and there are 360 images, which can also help you park in reverse, but the rear camera position is low, which may be covered by mud in rainy days. It is best to wipe it in rainy days.

In terms of intelligent driving, this version of my test drive does not have high-speed and intelligent driving in urban areas, but it has a lane intelligent cruise mode, which can drive at the set speed when the lane is set. If you encounter a vehicle in front of you, it will automatically accelerate and decelerate. To a certain extent, it can still better alleviate fatigue, but the power consumption will increase slightly after opening.

In terms of space performance, Tucki is relatively in line with his size, but personally, he feels that the seat cushion angle of the whole vehicle is relatively straight, especially in the back row. Then the spatial performance is basically the performance of an A-class car. The sitting posture of the main driver will be higher than that of the fuel car, and the driver’s seat needs to be adjusted to a slightly larger angle to be more comfortable.

Generally speaking, this car is very cost-effective in the price range of 120,000-150,000. Not only is it low in daily energy consumption, but it is also relatively easy to drive. At the same time, its experience and convenience are relatively advanced. It is perfect for daily urban transportation. I wonder if you are satisfied with the performance of this car? Let’s discuss it in the comment area!
