Turn waste into food! Efficient synthesis of starch and protein from corn stalk.

The joint team used the multi-enzyme molecular system containing cellulose degrading enzyme and starch synthase in vitro to biotransform with Saccharomyces cerevisiae, which can hydrolyze cellulose in corn stalk with high efficiency to synthesize artificial starch, and at the same time produce microbial protein by low-cost fermentation under aerobic conditions.
The rapid growth of global population and climate change will make mankind face great challenges to food security. Using synthetic biotechnology to efficiently convert agricultural waste resources into artificial food is one of the important ways to alleviate the food crisis and realize the sustainable development of agriculture.
Recently, Tianjin Institute of Industrial Biotechnology of China Academy of Sciences, together with Institute of Biotechnology of Chinese Academy of Agricultural Sciences, developed a new technology to efficiently synthesize artificial starch and single cell protein from corn stalk, which further reduced the production cost of artificial starch and provided a new way for grain production. Related research papers were published online in Science Bulletin (English version).
Producing starch from lignocellulose is expected to alleviate the food crisis.
The world produces about 200 billion tons of lignocellulose every year. Because each ton of lignocellulose contains about 40% cellulose, it produces about 80 billion tons of cellulose every year.
"Human beings can digest dextran linked by α-1,4-glycosidic bonds, that is, starch, but due to the lack of cellulose hydrolase, they cannot digest dextran linked by β-1,4-glycosidic bonds, such as cellulose, from lignocellulose. If the glucan composed of β-1,4-glycosidic linkage can be converted into the glucan composed of α-1,4-glycosidic linkage through enzymatic reaction, that is, using non-food biomass to produce starch is expected to alleviate the food crisis, which will be a great benefit for human beings. " Ma Yanhe, one of the authors of the paper and a researcher at Tianjin Institute of Industrial Biotechnology of China Academy of Sciences, said.
Developing multi-enzyme molecular system in vitro to improve the production efficiency of artificial food
In this study, in vitro multi-enzyme molecular system containing cellulose degrading enzyme and starch synthase was used for biotransformation with Saccharomyces cerevisiae. Cellulose in corn stalk could be hydrolyzed with high efficiency to synthesize artificial starch, and microbial protein could be produced by low-cost fermentation under aerobic conditions.
"In this study, we first created a low-cost efficient cellulose degradation and cellobiose production technology to remove β -glucosidase from commercial cellulase, effectively removed β -glucosidase from cellulase mixture, and used cellulose-enzyme-yeast complex to reduce the feedback inhibition of cellulose hydrolysate and improve the hydrolysis ability of cellulase." Zhang Wei, one of the authors of the paper and a researcher at the Institute of Biotechnology of the Chinese Academy of Agricultural Sciences, said.
Zhang Yiheng, a researcher at Tianjin Institute of Industrial Biotechnology, China Academy of Sciences, said: "Traditional biological manufacturing relies on living organisms such as microorganisms, plants and animals, but a lot of energy and sugar resources are used for self-reproduction, replication and life maintenance of organisms unrelated to biological manufacturing, which restricts the improvement of manufacturing efficiency. In vitro multi-enzyme molecular system is a new tool of synthetic biology, which completely avoids the above unnecessary waste and greatly improves the energy utilization rate, just as machinery replaces cattle in agricultural production, making it possible to achieve high production efficiency of artificial food. "
"One of the important technological breakthroughs in this research is the preparation of intracellular recombinant enzyme at low cost. The team transformed the recombinant enzyme expression strain, used cheap inorganic nitrogen source and glucose culture medium to carry out microbial culture at ultra-high density, and reduced the production cost of key recombinant enzymes to near the lowest theoretical value, achieving the production cost per kilogram of recombinant enzyme (dry weight) of only 250 yuan, which reduced the enzyme cost by about 1 million times compared with laboratory shake flask fermentation and conventional enzyme purification technology; The second breakthrough is that on the basis of using the existing low-cost cellulase, after removing β -glucosidase by new technology, cellulose can be hydrolyzed efficiently, stably and controllably, and its cost is nearly 1 million times lower than that of expensive purified cellulase. " Zhang Yiheng said.
This new technology has opened up a new way for the production of artificial grain, achieved the goal of securing China’s rice bowl with cutting-edge new technology, and realized "storing grain in technology, storing grain in mountains and storing grain in forests", which is expected to solve the economic dilemma of grain storage and consolidate the foundation of food security in China.

Belarus "sends" refugees to the EU border? Kegong: The situation on the border between Poland and Belarus is "shocking"

[Global Times reporter Yu Yang Ren Zhong Liu Yupeng] The border area between Poland and Belarus has become the latest front line for the western camp to compete with the Russian-Belarusian alliance. It is reported that in the past few days, the Belarusian army "escorted" nearly 1,000 refugees to the border of Bai Bo every day; As of the 9th, Turkish Airlines still sent refugees from Iraq, Syria and Afghanistan from Istanbul to Minsk, the capital of Belarus, twice a day. The Polish Defense Minister warned on the 8th that tens of thousands of Polish soldiers are ready to "defend the border". On the 9th, the European Commission accused Belarus of luring immigrants with "inhuman and gangster ways" and "false promises of easy entry into the EU". Belarus insists that the immigrants arrived there legally, and it was only transferred "as a hospitable country". "At that time, more than 2,000 Polish soldiers invaded Iraq for’ establishing democracy’. Why doesn’t Poland accept as many’ grateful Iraqis’ as possible today? " Russian Foreign Ministry spokesman Zacharova said this on the 8th.
Thousands of refugees from the Middle East and North Africa have recently tried to enter Poland from Belarus. The picture shows the Polish military police (behind the barbed wire) guarding the border between Poland and Belarus on November 8.
Polish border guards use tear gas.
The head of the Polish Border Service confirmed that a wave of illegal immigrants who tried to enter Poland from the Belarusian border had been stopped on the evening of the 8th local time, and these immigrants were still camped on the Belarusian side of the Bai Bo border on the 9th. The Polish Border Service announced that customs clearance at Kuznica port on the border of Bai Bo was suspended from 7: 00 on November 9.
According to the British "Guardian" report, the video released by Belarusian media on the 8th showed that white armed border police wearing combat uniforms led a group of people, including families with children, to a forest on the border of Bai Bo in an organized way along the border road. Critics believe that this is Lukashenko’s "dramatic attempt" to put pressure on Poland. Subsequent video footage showed that Polish border police used tear gas to drive people away because many people tried to cross the border through barbed wire. Polish helicopters hovered over the scene, and some immigrants shouted "Germany!" This is their final destination.
On the 9th, Polish President Duda accused Belarus of attacking the border between Poland and the European Union "in an unprecedented way". "This is an act of aggression that must be resisted to fulfill our obligations as a member of the European Union". Polish Defense Minister Bovashchak tweeted on the 8 th: "More than 12,000 soldiers have been on standby at the border." Polish Prime Minister Morawiecki warned Belarus on Facebook on the 8th: "The border of the Republic of Poland is not just a line on the map. It is sacred-in order to protect it, generations of Polish people have shed blood. "
The border between Bai Bo is more than 400 kilometers long, and the two countries also share the last virgin forest in Europe-Biawovieza forest, which makes it more difficult to prevent refugees from entering the EU. Poland’s Election newspaper called on NATO to "provide additional military assistance to Poland" to deal with the crisis.
On the 9th, White President’s Press Office said that Lukashenko and Russian President Vladimir Putin had a phone conversation to discuss Poland’s "severe actions against peaceful people". On the 9th, the Belarusian State Border Committee voiced through Facebook, "Foreigners near the Polish border expressed their intention to enter Polish territory and exercise their right to apply for refugee status from the EU. All these people, including women and children, do not pose a security threat and have no aggressive behavior. ""We do not rule out provocative actions by the Polish side to prove that the use of force and special means against refugees is justified. " On the 9th, the Belarusian Ministry of Defence also accused Poland of sending troops to the border with Bai Bo in violation of the agreement between the two countries.
Poland’s forced expulsion of border migrants has been criticized by human rights organizations. The border environment of Bai Bo is harsh, especially the temperature has dropped below zero degrees Celsius recently. CNN9 said on the 9th that the Polish government admitted that at least seven refugees died after crossing into Poland.
Russian Presidential Press Secretary peskov said on the 9 th that the situation on the border between Poland and Belarus is "shocking". "In this case, the most important thing is human life and health … We are paying close attention to this matter."
The "refugee flight" flew from the Middle East to Minsk.
According to the Guardian, this deadly crisis has escalated. According to Polish statistics, more than 30,000 refugees have tried to enter Belarus since August, and there were about 17,000 in October alone. Polish border guards told Reuters on the 9th that about 800 people camped at the place where they tried to cross the border the night before. Together with illegal immigrants stranded in the nearby forest, it is estimated that there are more than 4,000 people at present. According to the Russian News Agency reported on the 9th, the Lithuanian government is preparing for the possibility of similar "invasion", and the Ministry of the Interior proposes to declare a "state of emergency".
The EU accused Belarus of transporting illegal immigrants as a means to "retaliate against EU sanctions". Ursula von der Leyen, president of the European Commission, said in a statement on the 8th that the EU should now extend the sanctions against the Belarusian regime: "It is unacceptable to use immigrants for political purposes." She also promised to provide more support to countries such as Poland, Lithuania and Latvia to deal with the influx of refugees on the border, and said that the EU would explore "how to sanction, including blacklisting third-country airlines engaged in human trafficking".
According to the website of "EU Observer" and the BBC)9 reported on the 9th, Turkish Airlines and Dubai Airlines may be blacklisted by the EU for transporting immigrants to Belarus, and airlines from Syria, Iran and Qatar are also under consideration. According to the data of Minsk Airport on the 9th, Turkish Airlines still sends immigrants from Istanbul to Minsk twice a day. EU High Representative for Foreign Affairs and Security Policy borrell will visit the main countries of origin and transit of refugees in the next few days, including Armenia, Egypt, Iraq, Jordan and Lebanon, and call on them to take actions to prevent illegal immigrants from "falling into the trap set by Belarusian authorities".
The German newspaper Le Monde quoted German intelligence sources as saying that about 800 to 1,000 immigrants, mainly from the Middle East, arrive in Belarus every day. After their arrival, the Belarusian regime helped them to enter the European Union. The latest flight schedule of Minsk Airport shows that until March next year, the airport plans to have about 40 flights from Middle Eastern countries every week. Moreover, in the near future, the country will open five other civil airports to provide services for the "refugee route", among which Grodno Airport is only 20 kilometers away from Poland.
American citizens apply for asylum in Belarus.
On the 8th, the State Council spokeswoman Price expressed concern about "disturbing images and reports from the border of Bai Bo" and called on Minsk regime to "immediately stop planning and forcing illegal immigrants to cross the border into the EU". He also said that the United States "strongly condemns the political exploitation and coercion of the vulnerable groups by the Lukashenko regime, and the ruthless and inhumane facilitation of illegal immigrants to cross the border".
However, to the embarrassment of the U.S. government, American citizens actually applied for political asylum in Belarus. According to a report by Belarusian TV on the 8th, American Neumann, who is wanted by the Federal Bureau of Investigation (FBI) for attacking the police in the riots on Capitol Hill on January 6th this year, is applying for asylum in Belarus. After the FBI began to arrest him, he hid in Xizang in the United States, then fled to Europe, and then arrived in Ukraine in March this year, where he was still being hunted. In August this year, he was arrested by the Belarusian border forces while crossing the Ukrainian border. White TV said Neumann was "an ordinary American whose shop was burned down by’ black life is life’ activists" and "he lost everything and is being persecuted by the United States".
"The immigration crisis on the border of Bai Bo has rapidly evolved into an international event." The website of "EU Observer" said that the Polish special envoy to the EU will hold crisis talks with the special envoys of 26 other EU countries in Brussels on the 9th. NATO has a treaty obligation to protect Polish territory and has a multinational force in Poland. On the 9th, Germany urged the EU to "take action" to help Poland ensure border security. The German Bild newspaper described the incident as a "joint attack on the EU" by Russian President Vladimir Putin, Turkish President Erdogan and Belarusian President Lukashenko. German Chancellor Angela Merkel’s spokesperson Sebert told the Associated Press on the 8 th: "The Belarusian regime is acting as a human trafficker."
The Hill said that Belarus is one of Russia’s main allies, and the title of the white TV program about Neumann is "Goodbye America", in order to boost the anti-American propaganda supported by Russia.
Russian Foreign Minister Sergei Lavrov commented on the border crisis in Bai Bo on the 9th, saying, "Don’t forget where the legs grow". He said: "The policy towards the Middle East and North Africa that the West, including NATO and the European Union, has been pursuing for many years, that is, trying to impose a’ better life’ on them in the Western way. This is where the legs grow. I believe that to solve these problems, we must fully respect the principles of international humanitarianism. "

Lanzhou New District: Out of the Road of Green Development of Industrial Iterative Upgrading

Gansu, China Network October 18 th(Our reporter Song Fangke, Ren Lei, Yang Yanru) On October 18th, a network interview group from China on the mother’s river went into the chemical industry park in Lanzhou New District to visit the "liquid sunshine" ecological energy project and see the green industry leading the future energy development trend.
Lanzhou New District is the first in the northwest and the fifth national new district in China. Under the correct leadership of the Gansu Provincial Party Committee and the provincial government, and with the care and support of the Lanzhou Municipal Party Committee and the municipal government, Lanzhou New District closely follows the strategic positioning given to the new district by the state as "an important national industrial base and a demonstration area for undertaking industrial transfer", and makes a scientific decision according to the situation. In early 2018, it was decided to develop a green chemical industry in Lanzhou New District. Nowadays, the green industry in Lanzhou New District has gradually become a scale, leading the development of green energy industry.
The Outline of the Yellow River Basin Ecological Protection and High-quality Development Plan issued by the Central Committee of the Communist Party of China and the State Council mentioned supporting Lanzhou New District, Xixian New Area and other national-level new districts and Zhengzhou Airport Economic Comprehensive Experimental Zone to become refined and strong leading industries. Give full play to the role of Gansu Lanbai Economic Zone, Ningxia Yinchuan-Shizuishan, Shanxi-Shaanxi-Henan Yellow River Golden Triangle to undertake industrial transfer demonstration zones and improve the ability to undertake industrial transfer at home and abroad.
Lanzhou New District focuses on developing green chemical industry, and constantly improves its capacity to undertake industrial transfer. At present, the world’s first 1,000-ton-scale solar fuel synthesis demonstration project in Lanzhou New District Green Chemical Industry Park has basically completed all technical indicators.
The so-called solar fuel synthesis refers to the use of renewable energy such as solar energy, wind energy and water energy to generate electricity and produce clean and renewable liquid fuels such as methanol, which is called "liquid sunlight", which is also considered as one of the fundamental ways to solve carbon dioxide emissions in the future, and is also a new energy storage technology to collect and store renewable energy such as intermittent solar energy.
The project consists of three basic units: solar photovoltaic power generation, hydrogen production by electrolysis of water and methanol synthesis by hydrogenation of carbon dioxide. The project relies on the transformation project of scientific and technological achievements of academician expert workstation established by Academician Li Can of Dalian Institute of Chemical Physics, Chinese Academy of Sciences, and uses photovoltaic power generation and electrolysis of new high-efficiency catalyst to prepare hydrogen, and then uses new high-efficiency catalyst to build kiloton carbon dioxide hydrogenation to synthesize methanol.
In January, 2021, under the guidance of Academician Li Can and the team of experts, the world’s first 1,000-ton-scale solar fuel synthesis demonstration project was successfully tested in the Green Chemical Industry Park of Lanzhou New District, producing crude methanol, which marked the first step of the project to transform renewable energy such as solar energy into liquid fuel for industrial production, and realized the industrialization demonstration from laboratory research results.
According to reports, the project is of great significance to alleviate the energy security problems in China and even the global ecological civilization construction. On the one hand, it explores the optimal utilization mode of abundant renewable energy such as solar energy in western China, and provides an effective path other than UHV transmission for converting renewable energy such as solar energy into liquid fuel methanol; On the other hand, solar fuel methanol is a green hydrogen carrier, which can help solve the safety problem of hydrogen energy storage and transportation.
Just like the "liquid sunshine" eco-energy project’s green conversion of energy, Lanzhou New District Chemical Industry Park has been committed to the research of green and fine chemicals, in order to look for energy solutions with good environment and sustainable development.
At present, it is located in the northwest of Lanzhou New District, about 25 kilometers away from the core area of the new district, with a total planned area of 150 square kilometers. The infrastructure of water, electricity, roads, gas, steam and communication in the first phase (12 square kilometers) of the Chemical Industry Park has been fully completed and put into use, which fully meets the construction and production conditions of the landing projects. The investment in fixed assets has been 21.5 billion yuan, and it is expected that 50 enterprises will be completed and put into operation by the end of the year, showing a strong development trend.
More than 160 projects have been introduced into the park, with a total investment of over 27 billion yuan and more than 700 kinds of landing products. Among them, the "Specialization and Innovation" Chemical Science and Technology Industrial Park plans to build 600 special workshops, 200 buildings will be opened and 75 buildings will be put into operation, so as to build an international exclusive demonstration zone and an export base for "production, learning and research" of high-end chemicals in integration of defense and civilian technologies. Among them, more than 60 products, such as liquid crystal display materials, anti-tumor pharmaceutical intermediates and third-generation cephalosporins, have reached the international advanced level, which can effectively alleviate the shortage of corresponding products in China.

World Intellectual Property Day | ""is a network term? Do you know these signs?

""is a network term?

""is a variety show logo?

""is a whitening VC?

In daily life

We can often see these symbols.

But do you know what they represent?

【™】? Internet language?

In fact, what we often see is the abbreviation of "TradeMark", which is the trademark.

Trademarks include registered trademarks and unregistered trademarks that are directly used but not approved by the Trademark Office.

Among them, unregistered trademarks can only be protected by law to a certain extent if they reach a certain popularity.

[] Basketball team logo? Variety show logo?

When you see a package marked with "",this is the abbreviation of registered trademark "Register", which means that this trademark is a registered trademark and is protected by relevant laws.

Koko added

Logo≠ trademark, they are different.

LOGO is only a visual identification sign, and a trademark can clearly indicate the source of goods or services besides identification. Specifically, LOGO doesn’t need to be used in a certain industry or product. As long as you have applied for copyright protection, once others copy it, you can defend your rights no matter how far the industry is from you. The trademark must clearly specify which products are used, such as 25 kinds of clothing, shoes and hats. If other products, such as 20 kinds of furniture products, use the same trademark name, it does not constitute infringement.

Difference 1: the way to confirm the right is different

Logo, as an art work, does not need to be registered, and the copyright is automatically obtained when the creation is completed, while the trademark must be registered by the corresponding state authorities to obtain the trademark right.

Difference 2: different ownership of rights

The designer and owner of logo are probably not the same person. Ordinary companies have to entrust designers to design logo. As a commissioned works, the copyright of Logo belongs to the client in two cases, or it belongs to the designer if there is no agreement, and the trademark belongs to the trademark owner only. This is the category of intellectual property rights.

Difference 3: The laws of protection are different.

Logo is protected by Copyright Law and trademark is protected by Trademark Law. Logo can be registered as a trademark, so this trademark logo is protected by both the Copyright Law and the Trademark Law, which means that the protection scope of logo and trademark is different, and the protection scope of logo is not as wide as that of trademark. If the intensity of infringement protection is different, of course, the protection of trademarks is greater than that of copyright. If the copyright of the logo belongs to the designer, then if the logo is infringed, it actually harms the interests of the logo owner, but only the designer has the right to sue. The trademark owner can directly sue the infringement in his own name.

Difference 4: The duration of protection is different.

Logo as a work of art is generally protected for 50 years, while trademarks can be extended indefinitely, and the time of protection is unlimited.

[PATENT] Do you know this word?

The English word for patent is "patent". In China, patents are divided into three types: invention, utility model and design.

Generally speaking, the more patents granted, the stronger the core competition of an enterprise.

The most common "intellectual property" around us.

But the content covered by "intellectual property rights"

But it is far more than that.

There are also geographical indications and new plant varieties.

Trade secrets, integrated circuit layout design, etc.

In essence, intellectual property is an intangible property right, and its object is intellectual achievements or knowledge products, an intangible property or a spiritual wealth without form, and a labor result created by creative intellectual labor.

Like tangible property such as houses and cars, it is protected by national laws and has value and use value. The value of some major patents, well-known trademarks or works is far higher than that of tangible property such as houses and automobiles.

Its object has four characteristics: immateriality (my material achievements can be taken away, but my wisdom can’t be seen or touched by others), specific exclusivity (mine is mine, and others can’t take it), timeliness (remember to renew the fee when the time comes) and regionality (protected here, not necessarily elsewhere).

It is closely related to everyone’s life. Whether we open a book, listen to a piece of music, hold a mobile phone or even brush a short video on the mobile phone, there are intellectual property rights everywhere. Protecting intellectual property rights and intellectual labor results can better mobilize the enthusiasm of knowledge innovators, thus promoting economic development and scientific and technological progress.

Let’s join hands to jointly protect and respect intellectual property rights and create a good atmosphere for creating a new situation of building a strong intellectual property country.

Typhoon Feiyan has hit Japan, killing 11 people and injuring more than 600 people.

  China news agency, Osaka, September 5 (Reporter Lu Shaowei) Typhoon Feiyan, the 21st this year, landed in the south of Tokushima Prefecture, Japan, and the Kansai region of Japan was obviously affected by the typhoon. According to the latest statistics of NHK TV on the 5th, the typhoon has caused 11 deaths and more than 600 injuries in Japan.

  "Feiyan" was also designated by the Japan Meteorological Agency as the strongest typhoon that landed in Japan in the past 25 years. About 8 buildings were seriously damaged in the typhoon, and more than 1,700 buildings were partially damaged. According to the news of Kansai Electric Power Company of Japan, as of 7 pm, there are still about 350,000 households in Kansai.

  In addition, according to Osaka police, the typhoon also damaged about 2,000 traffic lights, and all of them can return to normal in two or three days with the repair.

  Affected by the pressure in the typhoon area, the tidal level in many sea areas has reached new highs, and the risk of seawater intrusion has increased. As one of the important transportation hubs in Kansai, an oil tanker was blown away by the wind and hit the airport contact bridge on the 4th, which made it impossible for vehicles to pass. About 3,000 passengers and hundreds of airport staff were forced to stay at the airport for one night, and they began to leave by boat one after another early on the 5th. The airport has been closed since the 4th. Due to the flooding of the airport runway and terminal building, some areas were blacked out, and it is uncertain when it can be reopened.

  The reporter learned from the Consulate General of China in Osaka that as of the morning of the 5th, there were still about 2,650 passengers stranded in Kansai International Airport, including more than 750 from China. The Consulate General attached great importance to the response to the passenger detention incident, and quickly launched the emergency mechanism. On the morning of the 5th, it dispatched the first batch of working groups to the vicinity of Kansai International Airport to learn about the stranded passengers in China and coordinate the countermeasures with the Japanese side.

  With the active coordination of the Consulate General, the Japanese side started the centralized transshipment of China passengers at 11: 30 a.m. on the 5th (originally planned at 8: 00 a.m., but postponed for some reason). As of 9: 00 pm local time, the Consulate General has assisted in transferring three groups of stranded China passengers to Osaka City, including the third group of 191 passengers. At present, a total of 551 passengers stranded in China at Kansai International Airport have been transferred.

  At the same time, the Consulate General actively coordinated China Southern Airlines, Tianjin Airlines, Sichuan Airlines and other airlines, urging them to properly solve the needs of stranded passengers to return to China by changing their air tickets and increasing flights free of charge.

The residential property has paid dividends of over 2 million yuan to the owners in the past three years.

  Recently, the news that a residential property in Ningbo, Zhejiang Province gave owners a red envelope for community income dividends triggered a heated discussion among netizens. The Beijing Youth Daily reporter confirmed from the person in charge of the residential property that it is real to pay dividends to the owners, and there is no speculation.

  Some people pay dividends of nearly 2000 yuan.

  Yang Shanfu, executive deputy director of the Third Industry Committee of Zijun Community, Panhuo Street, Yinzhou District, Ningbo City, Zhejiang Province, told the reporter of Beiqing Daily that the community property recently distributed public income dividends to the owners, and each person could get 226 yuan to 1996 yuan. He said that the current property management company was established in 2020, and in the past three years, it has paid dividends of more than 2 million yuan to the owners.

  Where did this more than 2 million yuan come from? Yang Shanfu said that the money comes from parking fees, advertising fees, store rental fees, etc. in public areas of the community, which belongs to the public benefits of all owners.

  A community owner who received dividends told the reporter of Beiqing Daily that he might save the money. Another owner, Mr. Zhou, said that he gave the money he got from the property company to the property company and used it to deduct the property fee for the next year.

  The residential property department operates independently by the industry Committee.

  Yang Shanfu said that the reason why the property company will pay dividends for the owners is mainly because the property company is operated autonomously by the community industry Committee. He introduced that two property companies were responsible for residential properties before, but with the passage of time, the service quality of the property declined a lot, which could not satisfy the owners.

  Yang Shanfu said that in 2019, there was a problem with the access control system in the community, but the maintenance work was not in place, which led to theft in the community. At that time, the owners of several units in the community spontaneously raised money to complete the maintenance of the access control system. At the same time, a pedestrian bridge in the community has also been damaged, and the owners of the community have spent tens of thousands of yuan in one day to repair the bridge.

  "In 2020, the community held an owners’ meeting and decided that the industry Committee would operate the property itself. In the same year, our property company was established." Yang Shanfu said.

  The owner, Mr. Rong, told the reporter of Beiqing Daily that before the establishment of the property company of the industry committee, the road surface in the community was bumpy and difficult to walk. After the industry Committee operated the property autonomously, the asphalt road was quickly completed. "Now there is something broken at home, such as a broken toilet or a broken light bulb. If you call the property, you will arrange for someone to come and repair it. After the repair, I will give the property some money symbolically. I will give 80 yuan for some laborious work and 20 yuan for labor-saving work. "

  Mr. Rong said that another time, a community owner found that there was a smoke from a household. "At that time, there was no one in this family. Someone immediately called the property and the staff went to the scene for the first time."

  The proportion of residents who consciously pay property fees doubled.

  Yang Shanfu said that before the property management committee independently operated the property management company, the proportion of residents in the community who paid property fees was only 40%, and now the proportion of residents who consciously paid property fees has doubled.

  Yang Shanfu said that at present, there are more than 2,400 households in Zijun Community, which are from all walks of life. "All the funds used by the industry Committee in the community are open to the owners, and all the owners are allowed to attend the meetings of our industry Committee. Before each meeting, we will also disclose what to discuss to all the owners." He believes that such measures can make owners fully understand the work of the industry Committee. "If the industry committee is doing something wrong and the service of the property management company is not in place, the industry committee should take the initiative to admit its mistakes and correct them. We hope that in the future, the residential property services will get better and better, and we will have another opportunity to pay dividends to the owners. " Yang Shanfu said.

The curtain of speeding up the merger of national and local taxes will open taxpayers to enjoy the biggest reform dividend.

  The curtain of the merger of national and local taxes, which has attracted much attention, will be officially opened. The reporter of the Economic Information Daily learned from authoritative sources that the reform of the collection and management system of national taxation and local taxation is in full swing, and matters related to the merger of national taxation and local taxation institutions at or below the provincial level are being stepped up. State Taxation Administration of The People’s Republic of China and other relevant departments have organized many internal investigations, trainings and symposiums. At present, the specific timetable and road map of the reform have been basically defined. The industry pointed out that starting from the concerns of taxpayers and payers, after the merger of national and local tax agencies, the transformation of collection and management functions and the convenience of taxpayers will be two major points of view.

  China’s current tax-sharing system originated from the tax-sharing reform in 1994. In the context of the continuous decline of central fiscal revenue in that year, the tax-sharing reform divided taxes into central tax, local tax and shared tax, aiming at increasing the proportion of central fiscal revenue and mobilizing the enthusiasm of the central and local governments. Then, after the reform of income tax sharing in 2002 and the comprehensive reform of camp reform in 2016, problems such as the inefficiency of local tax collection and management and the lack of local main taxes have become more and more prominent. In this context, a new round of national tax collection and management system reform is imperative.

  The Central Committee of the Communist Party of China’s Decision on Deepening the Reform of the Party and State Institutions, which was deliberated and adopted by the Third Plenary Session of the 19th CPC Central Committee, clearly put forward: reform the national tax and local tax collection and management system, merge the provincial and sub-provincial national tax and local tax institutions, and specifically undertake the duties of tax and non-tax revenue collection and management within the jurisdiction. After the merger of national tax and local tax agencies, the dual leadership management system with State Taxation Administration of The People’s Republic of China as the main body and provincial (autonomous regions and municipalities directly under the Central Government) governments will be implemented.

  The general direction of reform has been made clear, and implementation is also in full swing. The reporter learned from State Taxation Administration of The People’s Republic of China that on June 1st, a symposium on the reform of tax collection and management system was held in Beijing. CPC The Politburo Standing Committee (PSC) and Han Zheng, Vice Premier of the State Council of the People’s Republic of China emphasized that we should follow the principle of combining "slimming" with "fitness", seize key links and time nodes, solidly promote the merger of tax agencies, and adjust and optimize the functions and resource allocation of tax agencies. We should conscientiously implement the dual leadership management system and establish and improve the system and mechanism with clear responsibilities, smooth operation and strong guarantee. In accordance with the principle of mature batch and transfer batch, we will carry out the transfer of social insurance premiums and non-tax revenue collection and management responsibilities in a safe and orderly manner.

  The high-level forum held on June 1st released a positive signal of speeding up the consolidation of overseas local taxes. In fact, State Taxation Administration of The People’s Republic of China and other relevant departments have held many internal investigations, trainings and symposiums to convey the spirit, solicit opinions and discuss details. The reporter learned that, in order to promote the reform, State Taxation Administration of The People’s Republic of China has formed a working group on institutional reform by drawing the backbone from various departments and tax authorities at all levels. For more than two months, as the "headquarters" of tax institutional reform, it has become the norm for State Taxation Administration of The People’s Republic of China office building, No.5 Yangfangdian West Road, Haidian District to discuss overtime day and night.

  Experts in the industry pointed out that the reform of tax collection and management system is not only the merger of tax agencies, but also a profound change in the leadership system, operation mechanism, management mode and functions and responsibilities of tax departments, and it is also the great unity of law enforcement, service standards and business processes. It requires not only top-down design and indomitable spirit, but also the implementation of the spirit of "embroidery needle" at different levels.

  Starting from the concerns of taxpayers and payers, the industry pointed out that after the merger of national and local tax agencies, the transformation of collection and management functions and the convenience of taxpayers are two major points of view.

  Specifically, in this round of reform, the new tax authorities will accept the functions of non-tax revenue collection and management in many countries, such as social security.

  "This means that non-tax revenue such as social insurance premiums will be changed from self-collection and management by various departments to unified collection and management by tax departments, which is a major change in regulating the collection and management of government non-tax revenue." Hu Yijian, a professor at Shanghai University of Finance and Economics and dean of the Institute of Public Policy and Governance, said that it will undoubtedly make non-tax revenue and social security revenue more standardized in the system and more rigid in implementation, which will not only help reduce the cost of collection and management, improve the efficiency of collection and management, but also create conditions for future tax and fee system reform, unify the government revenue system, standardize the income distribution order, and consolidate the modernization foundation of state governance.

  It is reported that there are 1.088 billion cardholders in China by the end of 2017. "China’s non-tax revenue accounts for about half of the government’s revenue. After this transfer, the tax collection task of tax agencies will increase by 100%." Hu Yijian said.

  It is noteworthy that taxpayers are undoubtedly the biggest beneficiaries in the reform of the national tax collection and management system. The merger of national tax and local tax agencies has fundamentally solved the problem of "running at both ends" and "checking at both ends", effectively safeguarded the legitimate rights and interests of taxpayers and payers, continuously reduced the burden of tax collection and payment, and promoted the optimization of the business environment.

  "The integration of national and local taxes is not simply a matter of joining hands, but a win-win situation for both parties to reduce costs and increase efficiency by reducing institutional transaction costs." Yang Zhiyong, a researcher at China Institute of Finance and Economics, Chinese Academy of Social Sciences, said that this is not only an urgent need to deepen reform, but also carries higher expectations of taxpayers.

    In addition, "the merger of national and local taxes will have a far-reaching impact on the local economy and local government behavior in China in the future." Fan Zijun, a professor of public school of economics and management at Shanghai University of Finance and Economics, pointed out that in the long run, the combination of national and local taxes is conducive to the formation of a standardized and efficient tax system. After the merger of national and local taxes, the vertical management system will largely avoid the problem of low local tax collection rate. The increase of the collection rate will narrow the difference between the statutory tax rate and the actual tax rate, and at the same time clarify the expectations of enterprises on the tax payment level, which is also conducive to the implementation of tax reduction policies in the future.

  The curtain of reform is almost open, and more reform dividends can be expected. However, many experts also pointed out that this reform involves all aspects, and the difficulty, tight time and heavy tasks can be imagined. The details of the reform have yet to be introduced, and it is necessary to maintain determination and patience. "This reform is not only related to the integration of organizations, the adjustment of responsibilities, the change of management methods, but also to solving many practical problems such as cadre appointment, institutional setup, staffing, fund allocation, salary and treatment. Because the reform of tax collection and management system has its particularity, complexity and challenge, it is necessary to make overall coordination, comprehensively grasp, improve the vertical collection and management system, horizontal coordination mechanism, internal operation mechanism and external adaptation mechanism, and promote the reform smoothly and orderly, and also need more care and support from all walks of life. " Tang Jiqiang, a professor at Southwestern University of Finance and Economics and chief researcher at Xicai Think Tank, said.

  Li Haichao, a new generation archaeologist: I want to dedicate my life to Sanxingdui.

  "I have been excavating in Sanxingdui for three years, and I will dedicate the next 30 years, or even my whole life, to Sanxingdui."

  Li Haichao is the captain of the archaeological team at Sanxingdui Site of Sichuan University and a professor at the School of Archaeology and Culture of Sichuan University. At the event site, Professor Li Haichao proudly introduced the "treasure of the town pit" in the sacrificial pit of Sanxingdui No.7 — — Turtle-back-shaped grid-shaped device, he said, netizens gave it a nice name "Moonlight Box". When talking about the unearthed cultural relics and excavation work in Sanxingdui, Li Haichao’s eyes were smiling and shining.

  For archaeological work, sometimes a site needs a person’s efforts and exploration for more than ten years or even a lifetime, and the hardships and difficulties are self-evident. Since 1934, the predecessor of Sichuan University archaeology — — The museum team of West China Union Medical College University, led by Mr. Ge Weihan, started the first excavation in Sanxingdui’s history. By 1960, the Archaeological Teaching and Research Department of Sichuan University was established. Archaeologists of Sichuan University plowed the fields, inherited the ideas of Feng Hanji and Xu Zhongshu, and based on the fields, participated in a number of important discoveries of Bashu culture such as Sanxingdui, Jinsha and Lijiaba. Li Haichao said with a smile, "Well, we are already the fourth generation of Sichuan University archaeologists who stick to Sanxingdui."

  In May this year, the archaeological team of Sanxingdui Site of Sichuan University was awarded the 27th China Youth May 4th Medal Collective, and became the only youth collective in Sichuan Province to win this award. A new generation of young archaeologists has gradually shouldered the burden.

  Since its birth, China archaeology has shouldered the heavy responsibility of exploring the long history of Chinese civilization, and at the same time, it has also undertaken the mission of enhancing national self-confidence. Sleeping for thousands of years, waking up is shocking. The treasure of Chinese culture and the charm of ancient Shu culture attract young people from all corners of the country to join the archaeological excavation of Sanxingdui. Li Haichao said, "Today, I have been excavating in Sanxingdui for three years. I will dedicate the next 30 years or even my whole life to Sanxingdui to uncover the mystery of Chinese culture. "

  A generation has a generation’s mission, and a generation has a generation’s responsibility. Young archaeologists will inherit old skills and apply new technology from their predecessors, grow into talents in the front line of archaeology, continue to forge ahead and forge ahead, and will surely achieve fruitful results in exploring China culture.

  Fan Xiaokang, a graduate from Xinjiang: Rooted at the grassroots level like Populus euphratica.

The proportion of Uighurs in Jiashi County reached 99%, which is one of the deep poverty areas in the country’s "three districts and three States". Recalling the scene when he just started working, Fan Xiaokang said, "On the first day I arrived in the village, the villagers smiled and said to me, ‘ Son, are you 20 years old and will you be a secretary? ’ At that time, I felt that it was very difficult to communicate with the villagers, let alone carry out work. "

  Take root at the grass-roots level, accumulate wealth and accumulate wealth, and pool the wisdom of all people with my strength to create wealth together. In grassroots work, Fan Xiaokang gradually felt the simplicity, kindness and enthusiasm of the people in Xinjiang. He is determined to do grass-roots work well and help local people improve their lives. Combining the advantages of local characteristics, he learned from technicians and "local experts" to plant new plums and led the masses to double the income of new plums. From bilingual zero foundation to answering questions with the masses now; From being unable to start work to being handy now; From a college graduate to a party branch secretary recognized and supported by the masses.

  Now, like Fan Xiaokang, more and more young people, in their prime, choose to go to the grassroots, among the people and where the motherland needs them most. They are ambitious, down-to-earth, fearless of difficulties and obstacles, brave in the mission of the times, and integrate their personal ideal pursuit into the cause of the party and the country.
