At present, it is popular in novel coronavirus. At the same time, we also hear the news that there is no specific drug at present. Some people may ask: Why can’t we treat it with antibiotics?

Because the pathogen this time is a virus, not a bacterium!

What are the similarities and differences between viruses and bacteria? Why can’t we kill the virus with antibiotics?

Are tiny creatures on the earth.

Bacteria and viruses are microorganisms. As the smallest life form on the earth, people always ignore their existence, but this tiny creature is always painted with a sense of existence, and people will be infected by them if they are not careful.

Bacteria are cells, which have cell walls, DNA and organelles. They can produce and metabolize needed enzymes by themselves, and can divide and reproduce by themselves. Viruses are much smaller than bacteria, and the main structure is protein capsid and internal genetic material (DNA or RNA), and viruses cannot replicate themselves. Viruses need to replicate their genetic material by infecting host cells, and then release more offspring viruses to infect other host cells.

Bacteria can be harmless or even beneficial to human health, and can live independently. The purpose of the virus is to replicate itself, so it has no meaning unless it infects the host. It can be described as the purest "selfish gene".

The size difference between them is about 1000 times.

Bacteria in a broad sense are prokaryotes. Although they have a cell structure, they are still very different from human cells. Their structures are simpler, and they have no nucleus, but only a DNA aggregation area-pseudonucleus. Bacteria are generally spherical, rod-shaped, spiral, etc., and people do not forget to add a description of their shapes when naming them, such as Escherichia coli, Lactobacillus, Staphylococcus aureus and so on (ps. Yeast is a fungus, so there is no shape in the name.

At present, the smallest known bacteria are only 0.2 microns long, so they can only be seen under a microscope; The largest bacteria in the world can be directly seen by naked eyes, and it is 0.2-0.6 mm in size. It is a kind of bacteria called Sulphidophilus Namibia.

Bacterial size

Virus is a noncellular form composed of a nucleic acid molecule (DNA or RNA) and protein. It lives by parasitism and is an organic species between living things and nonliving things. After it enters the cell, its metabolism such as DNA replication is indeed the characteristic of living things, while after it leaves the cell, it is just a lifeless crystal.

Novel coronavirus electron micrograph 　

Most viruses are between 10 and 300 nanometers (nm) in diameter. Some filamentous viruses can be as long as 1400nm, but their width is only about 80nm. Most viruses cannot be observed under optical microscope, and scanning or transmission electron microscope is the main tool to observe the morphology of virus particles. Compared with bacteria, viruses differ in size by about 1000 times.

There are also different ways to invade the human body.

There are many "good people" in bacteria, among which saprophytic bacteria are important decomposers in the ecosystem, which makes the carbon cycle go smoothly; Some bacteria will carry out nitrogen fixation, so that nitrogen can be converted into forms that can be used by biology. The production of cheese, yogurt and fermented grains, the manufacture of some antibiotics and the treatment of wastewater are all related to bacteria. In the field of biotechnology, bacteria are also widely used. Of course, the "bad guys" in bacteria are many pathogenic bacteria, including tuberculosis, anthrax, plague and other diseases are caused by bacteria.

The relationship between bacteria and human body is mainly parasitic. Let’s mainly talk about pathogenic bacteria. Because most bacteria have their own metabolic system, bacteria can be parasitic between normal cells of human body after invading human body. Bacteria take away the nutrients necessary for the body; The growth of bacteria produces various metabolites, which disrupts the physiological balance of the body; Even the size of bacteria has become a pathogenic factor, which interferes with and destroys the function of cells. Therefore, in some diseases, the proliferation of bacteria alone has fatal consequences.

The virus may have invaded the human body from a sneeze or a physical contact. Viruses need to parasitize in living host cells, and rely on host cells to provide the raw material system, energy and place needed for virus replication. When a virus is ready to infect a host cell, it needs the following six steps to complete its proliferation activities, namely adsorption, invasion, hulling, biosynthesis, assembly and release.

Adsorption: The virus "targets" the target cell by recognizing the specific receptor protein molecules on the surface of the host cell membrane (for example, novel coronavirus virus recognizes angiotensin converting enzyme 2 -ACE2)； on the surface of human respiratory tract and lung cells); Invasion: then the virus either enters the host cell in some way (such as membrane fusion) or directly injects genetic material into the host cell; Shelling: Immediately after the viral infectious nucleic acid is released from the capsid; Biosynthesis: "non-stop" biosynthesis-synthesizing virus nucleic acid and protein according to gene instructions and with the help of raw materials, energy and places provided by host cells; Assembly: The newly synthesized virus nucleic acid and protein will be assembled into progeny virus; Release: the progeny virus is released outside the host cell.

Human body’s defense and counterattack

Both bacteria and viruses have to break through the human body’s defenses to complete the invasion, but the human body will eventually find their existence, and the human immune system has its own protective measures and early warning mechanism.

The first line of defense: skin and mucous membrane. The first way for human beings to protect themselves is defense, which makes the human body form a relatively closed system through the skin and mucosa. When harmful substances are about to invade the human body, the skin and mucosa will block the external pathogenic factors out of the body.

The second line of defense: bactericidal substances and phagocytes. There are always bactericidal substances and phagocytes patrolling the mucosal surface and inside the human body to prevent the invasion of pathogens. Take lysozyme as an example, it can destroy the cell wall of bacteria, cause the contents of the cell wall to escape and dissolve the bacteria, and can also directly combine with negatively charged virus proteins to form double salts with DNA, RNA and apoprotein, thus inactivating the virus. Therefore, the enzyme has antibacterial, anti-inflammatory and antiviral effects.

The third line of defense: specific immunity. When the powerful pathogen broke through the first two lines of defense, the human body’s counterattack just began. Through the phagocytosis of phagocytes and the analysis of special immune cells (T cells), the human body has produced antibodies that can specifically recognize invaders. The antibodies can make pathogens stick together and no longer be invasive, and finally the pathogens exposed between cells will be killed. But is the virus that invaded the cell safe? No! The human body can subtly identify which cells are infected by the virus, and then send a "killer" to kill the infected cells and release the virus inside the cells for antigen elimination.

However, it takes time for the human body to fight back, and pathogens will invade and occupy the human body through such a time gap!

Auxiliary appearance: drug therapy

Bacterial infection once became the greatest enemy of mankind. For example, the plague was called the "Black Death" in Europe, which reduced the population of Europe by one third in three years. At present, plague and cholera are classified as Class A infectious diseases in China. It was not until the discovery and popularization of antibiotics that human beings controlled the outbreak of bacterial infection.

Antibiotics mainly kill bacteria by destroying the structure of bacterial cells, such as cell wall, cell membrane, changing internal metabolism, hindering the synthesis of nucleic acid and protein, etc.

Chemical structural formula of penicillin

However, antibiotics are ineffective against viruses! Because bacteria and viruses have completely different structures!

Because bacteria have cell walls, as well as their own nucleic acid replication machines and ribosomes, antibiotics can kill bacteria with little side effects on humans as long as they are designed for these targets. However, the virus has no cell wall, its own nuclease and ribosome, and all its functions depend on the host cell. So antibiotics can’t kill viruses (we can’t make an "antibiotic" that kills host cells).

The ideal antiviral drugs can not only act on one or several links of the virus proliferation cycle, but also interfere or block it without affecting the normal metabolism of host cells. For example, ribavirin, a common drug, provides a large number of nucleotide analogues, which replace normal nucleotides, making the virus lose its replication ability and play a role in inhibiting virus amplification (but it also has great side effects on human body). In addition, the anti-influenza drug oseltamivir works by blocking the release of the offspring virus.

In view of this pneumonia epidemic, researchers from Wuhan Institute of Virology, China Academy of Sciences and Academy of Military Medical Sciences have also preliminarily screened out ramidivvir (GS-5734, phase II clinical anti-Ebola drug) and Chloroquine (Sigma-C6628, antimalarial drug) which have good inhibitory effects on novel coronavirus (2019-nCoV) at the cellular level.

But we have to say that in the face of virus treatment, human beings have never found a universal specific drug like antibiotics. Active treatment is to mobilize the human body’s own immune ability to fight against viruses, because only organisms themselves really know how to fight against organisms.

　　Beijing Youth Daily News In order to vent his emotions, he used a slingshot to shoot a projectile. The man Anmou broke three glass curtain walls in the East Hall of Houshayu Station of Beijing Metro Line 15. Yesterday, the Beijing Youth Daily reporter was informed that the Shunyi court sentenced Anmou to two years in prison and suspended for two years for the crime of seeking trouble.

　　At 19 o’clock on April 11, 2019 and at 21 o’clock on May 10, 2019, Anmou drove a truck from north to south on Jingmi Road, passing through the east side of Houshayu Station of the subway, and used a slingshot to fire bullets to vent his emotions. Three glass curtain walls in the east hall of Houshayu Station of Line 15 subway were broken.

　　It is reported that "bullet holes" appear in the glass curtain wall of Houshayu Station in Shunyi, Metro Line 15. Police officer Zhao of the Criminal Investigation Detachment of the Public Transport Corps of Beijing Public Security Bureau said: "This kind of special glass is not easy to break if it is not acted by external force, and scattered steel balls are found on the spot." After receiving the report, the Criminal Investigation Detachment of the Public Transport Corps set up a task force in conjunction with the police station of Fengbo Station and sent a number of investigators to investigate.

　　At about 9: 50 pm on May 11th, an investigator found that when a closed pickup truck passed Jingmi Road outside Houshayu subway station, the driver rolled down the window and took out a slingshot, "shooting" at the glass curtain wall and quickly fled after breaking the glass. Then the police quickly found the man Anmou in a community in Houshayu and arrested him.

　　"We got more than 90 steel balls, 11 clay balls and a slingshot in the car." Zhao police officer said that when he saw the arrival of the police, Anmou confessed his behavior. "Breaking the glass to vent his dissatisfaction, I regret it now."

　　Anmou, a water delivery worker, said that he was in a bad mood because of conflicts with his family. In order to vent his emotions, he took out his slingshot and shot steel balls on the glass when he walked to Jingmi Road outside Houshayu subway station. After driving around, I shot at the second glass.

　　After identification, the loss price of three damaged glass curtain walls was 62,700 yuan. His family has compensated the victims for their losses. Anmou obtained the understanding of the victim unit. Anmou was prosecuted to Shunyi court for allegedly seeking trouble.

　　After trial, the court held that Anmou arbitrarily damaged public property, and the circumstances were serious. His behavior violated the social public management order and constituted a crime of seeking trouble and should be punished. In view of the fact that Anmou truthfully stated the facts of the crime, pleaded guilty and repented, and had compensated the injured unit for economic losses and obtained understanding, he was given a lighter punishment and suspended sentence according to law. In the first instance, the court sentenced Anmou to two years in prison and suspended for two years for the crime of seeking trouble.

　　(Beijing Youth Daily reporter Song Xia correspondent Geng Ruoshi)

Producer 500, director Buick accepted an exclusive interview with 1905 Film Network.

Special feature of 1905 film network In director Buick’s mind, the film can be better, because many of the original contents of the script were taken away by him because of the length of time.

Then, in his view, how many points can this version of "Door Lock" with still guaranteed standards have? With this curiosity, we walked into his various responses to Door Lock.

Stills of "Door Lock"

Since the release of the film "Door Lock", the evaluation has its own controversy. As a movie, this is the norm. Whether it’s producer 500 or director Buick, it’s already predicted.

In the eyes of 500, this controversy happens to be the charm of Buick as a new director. He has all the courage of young people, and he also has insufficient experience in directing a tube.

No matter what the audience’s recognition of the essence of the film is, we can pay attention to the security situation of women living alone from "Door Lock", and perhaps this film has been successful. As Bai Baihe said at the premiere, attention itself is a kind of strength.

01　create

After Buick won the Best College Student Short Film Award in the 8th China International New Media Short Film Festival with the short film "Salvation", he received many scripts.

Director Buick accepted an exclusive interview with 1905 Film Network.

Without exception, these scripts are mostly remakes of suspense themes. In addition to "Door Lock", what impressed him deeply was a work related to the escape of the Chamber of Secrets.

The theme of suspense and horror is Buick’s preferred style. Even in the short film "Salvation" with the theme of war, we can also gain insight into his ability to control this type.　

If we simply want to make the suspense type to the extreme in form, then the story of the escape from the Chamber of Secrets can already be supported, but from the content level, there is still something missing as a whole. At the suggestion of 500, and combined with his own experience, Buick finally chose "Door Lock".

Five hundred was the judge of the short film award at that time. In his eyes, this new director is very special, and he has wildness that other domestic directors don’t have. If possible, two people can make a big ticket together.

However, Buick only has short film experience, from short to long, which is not simple. He knows that he needs a springboard, and 500 knows that this "dumb-headed" needs more practical experience in order to better shoot feature films.

Five hundred handed Buick the book of the series aiming. After watching it, Buick was poked by the very cinematic narrative of the previous episodes, and then took it down. However, commercial works are no better than students’ short films, and each type of work corresponds to different staff. Directors also need to have stronger leadership and external communication skills.

During the filming of Aiming, 500 made Buick more immersed in creative work. But when it came to "Door Lock", he really "pushed" Buick out.

As a producer, 500 gave Buick a lot of advice in the early stage of script creation. The script was read over and over again, and then the shortcomings were found in the middle to fill this gap. As a new director, Buick hopes to highlight his own style to the extreme in this work.

Five hundred rejected the idea. "There is still some life-oriented content in this movie to touch the more emotional places of the audience."

During the whole preparatory stage, Buick will have his own anxiety, and he will fall into a strange circle — — Why are these things different from what you think?

Five hundred told him, "The farthest distance between people is’ I thought’". In the communication between the crew, we must not simply use abstract words such as texture to describe it, but must form more specific words or pictures so that the crew can understand it.

Combining these valuable experiences, the script was also changed to a more satisfactory version, and Door Lock was formally established and started in Xiamen in September 2020.

02　"hiding the murderer"

When Buick got the script, it had made some adjustments compared with the original story, but in their view, these adjustments were far from enough, especially where suspense was hidden.

Do you want to hide? How to hide it?

The most curious thing about "Door Lock" is the identity of the man in black. For suspense movies, decryption is something that the audience can’t wait to do in the process of watching movies. If the identity of the man in black is put at the end, but the audience guesses it in advance, the whole mystery laid in the early stage will become very embarrassing.

"You should never think that you are smarter than the audience. Now the audience is too smart. The more you hide, the more self-defeating. In this case, it is better not to hide. " Five hundred, who is quite experienced in suspense subjects, gives his own bottom in his creation.

Buick also found a creative idea. "I don’t want to make a pure suspense film. The murderer is not the key issue, but the female issue is."

After the problem of "hiding the murderer" was solved, Buick’s creation also took shape. For example, in the subway, Fang Hui (played by Bai Baihe) and Qiao Xiaoman (played by Qiao Xiaoman) have a more definite place.

Even so, in the process of creation, 500 and Buick still had some disputes.

Five hundred told Buick that Fang Hui and the boss must be filmed in the movie. But in Buick’s view, it is not necessary. If there is already a scene in the movie where Fang Hui is harassed in the office in order to show the weakness of women in the workplace, then the drama of the wine bureau is very cumbersome.

"Door Lock is about women’s independence. She is not only in the office, but also in all aspects of life. Then the wine bureau is an essential drama, and this is also a place where the audience can be more empathetic." Of course, 500 did not strongly ask Buick to add this content. "You can shoot it first, and then deal with it when editing."

Finally, in the editing stage, there were two versions as a whole; One is more life-oriented, and the other is more typed. From the perspective of genre preference and lens design during shooting, Buick is not satisfied with the life-oriented version, but he understands that "Door Lock" is to let the audience pay attention to women’s safety issues, so pure genre expression will weaken its power.

Combined with the story of life flow and stylized type expression, in Buick’s view, the most complete version of "Door Lock" should be two and a half hours. "The story should be one thing that Fang Hui experiences every day, which slowly accumulates and finally erupts." However, this version does not meet the requirements of a genre film, which is not conducive to the audience’s impression and the cinema’s film arrangement.

Recalling the entanglement in the editing, Buick did not forget to reflect. "These problems can actually be avoided from the script stage. If the plot is set in place reasonably, there will not be so many plot pictures that cannot be abandoned during the editing process."

03　cut down

"If you follow my script, it is actually particularly suitable for processing into a mini-drama with three or four episodes, and each character will have a good display." However, as a film, "Door Lock" must be cut by Buick.

In the original version of Door Lock, the opening was as long as 15 minutes. In the view of 500, this paragraph can be presented to the audience as a short film in the form of a pilot notice.

"There is actually her ex-boyfriend in front of the story, from the girl going home to meeting her ex-boyfriend, including the atmosphere in the corridor. Moreover, in that kind of old building, when you open the door, you may hear a cough upstairs. These thoughtful and fearful things have all been written in by me. And in that story, there are still some conversations between her and her ex-boyfriend, which explain the background of many characters. "

Buick read a lot of news information and combined with his own experience to create this story. Including the opening, many viewers will be curious, why do men in black lie on the top of the wardrobe? "These are not my whimsical creations, but there are cases that can be studied in reality."

In addition, in the story line of the dog farm at the end of the film, there is also a very important scene, which was deleted for the sake of time. This also indirectly led to the current audience’s controversy over the plot in the second half of the film.

"It was a self-help drama of Fang Hui, and the whole narrative was edited in parallel from the perspectives of Fang Hui and Zheng Fei (played). Fang Hui was in a coma and remembered Qiao Xiaoman’s saying in the subway,’ Hold on, hold on, that’s how you were domesticated’. Then she slowly woke up and saw the door next to her closed and two dogs. She used the coma medicine left by Zheng Fei, and injected it into the sausage. As a result, a dog died directly after eating it. Then she directly pulled the main switch and the electronic door next to it opened. She found Qiao Xiaoman and pulled her up. Another dog ran after them. Although she passed the first door, she finally got stuck at the second door. At this time, Zheng Fei came back. Zheng Fei saw everything in front of him, and there was a line,’ Why did you kill my dog?’ "

In the original play, there are women’s self-help and the mutual help of "girl helps girl", and at the same time, it can let the audience see the emotional changes of the role of Zheng Fei in the later stage of madness.

Buick excitedly revealed these cuts to us, but he couldn’t help sighing that they were all caused by inexperience. "The next play will pay attention to these contents from the script stage."

04　Fei Zheng

Without the support of these stories, the audience have a better question about the role of Zheng Fei, and why he became such a person.

In Buick’s creation, Zheng Fei has a prototype.

"Why is his name Jeffrey? In fact, this man is a notorious pervert murderer in the United States. He is very similar to the situation in Zheng Fei. Their external images look good, but in the end, they are found to be very dark inside, and even do a lot of unsightly things. I remember the documentary at that time asked Jeffrey, saying that you have good conditions and good looks, why can’t you fall in love with people normally? The reason for his answer is’ because I want to’. The simple answer is that we can’t think with the logic of normal people at all. They pursue absolute control and must do things according to their wishes, which is the same as Zheng Fei’s strong desire for control. "

It is based on this idea that Buick insisted on retaining the dialogue between Zheng Fei and Fang Hui in the car during the deletion process. "In addition to explaining the background of the characters, this scene actually implies Fang Hui, and she has no right to know it. If you want to break this paper, it will be finished."

Although the audience will have a lot of questions and make the film controversial after the deletion of "Door Lock", in Buick’s view, this may be the deficiency of being a new director, and it is also a place to make up for it in the future.

As for "Door Lock", how many points do you give?

Buick said 70 points.

CCTV News:As the major e-commerce platforms start mid-year promotion activities, since June, nearly 400 million express parcels have flowed across the country every day. However, in the interview, the reporter found that the big box is covered with small boxes, and the box is filled with plastic foam, and the goods … … There are still many such phenomena of over-packaging of express delivery.

CCTV reporter Tang Ying:These parcels are all goods I bought from different e-commerce platforms. Let’s take a look at their packaging. Let’s take a look at what’s in this big package. When we open the package, we first see a foam film, which has two layers. There are bought tea leaves in it. We measured the length of the two films, the short one is 105 cm and the long one is 165 cm. In fact, let’s try it. This short film can wrap the tea leaves, and it can also play a role in ensuring the safety during transportation.

The reporter calculated that the size of these removed packages is almost five times that of the purchased goods. Because many of them can’t be reused, they can only be sent to the garbage collection station, which has become the "main force" of domestic garbage.

General Station reporter Chen Qingbin:In the recycling station in this community, we see that the largest amount of recycling in the site is this kind of carton. These cartons have been sorted and arranged, in addition to some foam boxes and plastic articles like this. All the recycled items in this site will be recycled by recyclers every day.

　　　　　　 The staff told reporters that there are currently about 200 sites like this in Tianjin, and the daily processing and recycling volume is about 5 tons, of which express packaging waste accounts for about 80%.

Innovative research and development of green packaging to break through the technical cost difficulties

At present, China’s express delivery industry has an average daily business volume of 350 million pieces and nearly 700 million daily service users, ranking first in the world for many years. It is not only urgent to properly solve the problem of over-packaging of express delivery, but also the inherent requirement of industry transformation and upgrading and sustainable development. The key to "slimming" express packaging is to start from the source and work hard on packaging design. So, what about the research and development of recyclable green packaging? What is the difficulty of R&D and promotion? With this question, the reporter came to China Post Green Packaging Innovation Laboratory.

CCTV reporter Tang Ying:This is the research and development site of China Post Green Packaging Innovation Laboratory. The packaging prototype behind me is making samples according to the design drawings of the researchers.

Gao Kang, packaging engineer of China Post Green Packaging Laboratory:After the box is glued, it will undergo some physical tests such as falling, vibration and impact, which can meet the safety verification of the contents in real scenes. If it doesn’t meet the standard, we will consider making some adjustments from the paper it uses to increase the grammage of the paper, then we will make a material selection of the paper, then redraw the drawing, repeat this action, and then test it until it meets our requirements.

In addition to cartons, various items often used in express delivery, such as bubble film and adhesive tape, will be tested for many rounds. R&D personnel said that it is the focus and difficulty of R&D to wrap the tape frequently.

Kang Li, Technical Director of China Post Green Packaging Laboratory:Compared with the traditional ordinary adhesive tape, it may not be as strong as the traditional adhesive tape, reaching a level of 50%, and its cost has increased by nearly two times.

In order to solve this problem, Kang Li and his colleagues conducted numerous tensile tests and observed the curves in real time. After nearly two years of continuous efforts, a new type of biodegradable environmental protection adhesive tape was finally launched this year. When garbage is recycled, the adhesive tape can not be separated from the carton, and under suitable conditions, the adhesive tape can be directly degraded into water and carbon dioxide.

In the green packaging innovation laboratory, the reporter found that many recycling boxes that have been developed for a long time are rarely seen and used in daily life.

Kang Li, Technical Director of China Post Green Packaging Laboratory:The scene it uses is relatively fixed at present. It (needs) to be able to sign in person and take back the box. If this (if) is put in the self-reporting cabinet, it is difficult for the courier to recycle it. As a courier company, its loss rate is also relatively high, so we need to build an intelligent management system step by step now.

　　　　　　 Kang Li told reporters that at present, the usage of recycling bags in China’s postal enterprises has reached 96%. However, compared with the business volume of postal enterprises and the whole industry, there is still much room for improvement in the usage and recycling times of recycling packaging at the end of express logistics.

Express delivery enterprises explore and promote the "greening" of the whole process

Express packaging should not only ensure the safety of goods, but also avoid waste. How to find a balance between the two? In the investigation, the reporter found that more and more express logistics enterprises attach importance to and think about this issue, and promote the "greening" of the whole process in various ways to "slim down and reduce the burden" for express packaging.

At a courier outlet in Yiwu, Zhejiang, the reporter saw that the green delivery block was specially divided. Consumers can accumulate the number of express packages they bring and exchange them for delivery fees between different cities. In the transportation link, express delivery companies have replaced the former 9.6-meter van with a high-capacity trailer with a length of 15 to 17 meters, which can reduce the pollutant emissions per unit express by more than 70%. Following the transport vehicle, the reporter saw the green smart environmental protection bag in the sorting center.

Zhu Zhongchen, Deputy Manager, Personnel Integrated Management Group, Yiwu Center, Zhejiang, ZTO Express:This package is now recycled more than 110 times, and a chip is inserted at the same time, so that it can be automatically sorted in this system. Through the popularization and application of E-mail, we can reduce the pollutant discharge of paper by more than 60% in the later transit link. Basically, we have achieved a recycling of everything now, which actually creates a closed loop, which truly reflects a core green environmental protection value.

　　　　　　 In the postal processing center in Guizhou, the reporter saw that many e-commerce products began to use a green circulating clearing box. Compared with traditional cartons, this box no longer needs tape sealing, and the box comes with a lock, just sticking a self-adhesive address sheet.

The proportion of no secondary packaging is expected to reach 90% by the end of this year.

As a big country of express delivery, the management of over-packaging of express delivery has always been a common concern of all walks of life. As early as 2009, China carried out special treatment of express packaging. In April 2021, the State Post Bureau issued the "Special Treatment Plan for Overpackaging and Random Packaging of Mail Express". After many efforts, the green development awareness of the express delivery industry has gradually increased. The relevant person in charge said that by the end of this year, we will strive to achieve 90% of e-commerce express mail no longer being repackaged.

According to the latest data of the State Post Bureau, according to the parcel spot check in May, 380 million pieces of mail express with recyclable packaging were used, and 350 million corrugated boxes with good quality were recycled. In March this year, the State Post Bureau issued the "Implementation Opinions on Promoting the Green and Low-carbon Development of Postal Express Industry", which clearly stated that it is necessary to speed up the construction of a recycling system for mail express packaging and promote the construction of a pilot project for the large-scale application of recyclable express packaging supported by the National Development and Reform Commission.

Guan Aiguang, Deputy Director of Market Supervision Department of State Post Bureau:The green management of express packaging involves many subjects, long chain and wide fields. In the process of promotion, all departments need to work together to accelerate the formation of a situation of joint management; It is necessary for the state to introduce more preferential tax and fee subsidy policies and increase the supply of green packaging for express delivery; It is necessary for local government departments at all levels to increase support and solve the difficult problems such as high cost of recyclable packaging, difficult recycling and less support.

Guan Aiguang said that the promotion of green packaging is a systematic project. At present, with the wide application of green packaging such as electronic waybill, slimming tape and lightweight box, China has basically entered the 2.0 era of packaging reduction. In this period, it is necessary to turn to material and technological innovation, such as the development of new materials, new packaging containers, intelligent packaging systems, etc., to achieve the goal of collaborative reduction from the upstream and downstream of the supply chain.

On the other hand, the recycling packaging market at the end of logistics should achieve a technical breakthrough. Popularizing and applying recycling packaging is an important part of green postal strategy and an important means to explore the green transformation of packaging.

Guan Aiguang, Deputy Director of Market Supervision Department of State Post Bureau:By the end of the year, the proportion of e-commerce express mail will not be repackaged to 90%, and the two special treatments of over-packaging and plastic pollution will be further promoted. One billion pieces of mail express mail will be packaged by recyclable express delivery, and 800 million corrugated boxes with good quality will be recycled.
