　　In the summer of 2023, "dopamine" was a hot word. Wearing a blogger’s raiders video and a fashion artist’s business trip makes "dopamine wearing" a new fashion that has to be mentioned. Not only that, the street gardens in Shanghai’s urban renewal, the color matching of new retail foods such as milk tea, bread and coffee shops make "dopamine color matching" full of urban people’s vision.

　　This summer, "dopamine", a proper term originally in the field of psychology, suddenly broke into the mass consumer market. Without "dopamine color matching", it seems that it is not a "fashionable essence". What exactly is dopamine? Dopamine color matching, why make people happy? Let’s walk into the world of dopamine together.

　　Secrete "happiness"? Look down on dopamine

　　Dopamine is an important neurotransmitter in the brain. In 1957, a doctor named Catherine montague found dopamine in the laboratory of a hospital near London. In the human brain, only one in 200,000 brain cells can produce dopamine. Although the content is small, dopamine has a great influence on people’s spirit and emotions, and is closely related to information and emotions such as pleasure, excitement and happiness.

　　Is dopamine important? Very important! In the past, people always thought that dopamine was a happy molecule and that as long as it was secreted, it would be happy. This cognition is actually biased. Dopamine is an important component of reward loop, and its secretion is not so much related to happiness as to the surprise when people "get".

　　For example, love. When we meet for the first time, we will feel "Wow, love in the city" in our hearts and be instantly attracted to each other. In the follow-up communication, the boy’s humor deeply attracted the girl, and the girl’s gentleness moved the boy silently. During these processes, dopamine in people’s brains is secreted in large quantities, and people feel passionate. However, when two people really live together around pots and pans, all kinds of problems emerge, and both sides will think, how did they make such a strange decision in the first place? Why? At this moment, the dopamine concentration dropped and the passion retreated. In other words, the passion, happiness and excitement of human beings come from dopamine produced in the process of chasing when people don’t get it.

　　For another example, when a girl buys a beautiful skirt, she will feel very happy and want to wear it often. But after she wore it several times in a row, she began to think that this skirt was so much, and began to chase other beautiful skirts. This is also related to dopamine. When I first saw the skirt, "good love" was true, and the desire of "never having it, wanting to have it" made the brain secrete dopamine. And when you have it, with the freshness of the past, dopamine secretion decreases, and the girl’s love for the skirt also declines. At this time, if there are other excellent skirts, dopamine will be "awakened" again, so it will "find another new love".

　　It can be seen that dopamine is more accurately a molecule of expectation and desire than a molecule of happiness. In other words, the secretion of dopamine comes from the reaction to accidents.

　　Drive mankind to "go further and live better"

　　However, it is undeniable that dopamine is extremely important, because it makes human beings go further and live a better life. In the process of studying the origin and migration of human beings, scientists have found that people who migrate farther will secrete more dopamine than those who live in places of origin such as East Africa. The same is true of Darwin’s theory of "survival of the fittest", because the "fittest" secrete more dopamine, they are more willing to explore, more enterprising, more willing to take risks, and more willing to get more things for themselves, thus surviving.

　　Back to the beginning of the article, "dopamine penetration" is also related to "living better", a word coined by a fashion psychologist. When she was depressed, she searched hard for ways to arouse her inner passion. One day, she found that dressing together was also a way to adjust her mood, so she had an "emotional enhancement dress", which was the predecessor of "dopamine wearing".

　　As you can see, bright and gorgeous colors are the core of "dopamine wear". According to the research of color psychology, "people’s first feeling is vision, and the biggest influence on vision is color". Color can stimulate people, thus affecting their mood. The key to "dopamine penetration" lies in the direct collision between high-brightness colors, which make people shine and awaken their excitement. In addition, rich and exaggerated printing patterns and shapes can also bring shock and impact to the vision, thus prompting the human body to secrete dopamine and produce a pleasant feeling.

　　Some people think that "dopamine penetration" is popular because it conveys positive information through light, shadow, color and shape, forming a "positive association", which has a certain effect on improving mood. In fact, there are precedents for similar scenes in life, such as "dopamine space", "dopamine architecture" and "dopamine landscape", all of which use bright colors and interesting patterns in design to drive people’s emotions.

　　"Desire loop" and "control loop" that must be known.

　　Every time we talk about dopamine, we have to mention the midbrain marginal pathway, which is the "desire circuit" of dopamine. Desire begins in the ventral tegmental area of the brain, which is one of the main production areas of dopamine. When the cells in this area are activated, dopamine can be released into the nucleus accumbens, which gives human beings the motivation to do something. For example, our excessive shopping and addiction to the internet are all related to the excessive function of dopamine "desire circuit".

　　Here, a question will follow: how can we reduce the powerful control and influence of dopamine "desire circuit" There is a method called "Dopamine can control dopamine". There is a circuit in the frontal lobe of the brain, which is called "control circuit". Contrary to the previous "desire circuit", the effect of dopamine secretion by the "control circuit" is ruthless and careful, that is, dopamine can reach a balanced state under the adjustment of the "control circuit".

　　But the problem comes again. Many human brain functions have not been clearly developed, and it is impossible to accurately adjust the "desire circuit" and "control circuit". What should I do with my dopamine? Two methods may help you strike a balance.

　　Learn to pay attention to reality. When people blindly pursue success and pleasure, please pay attention to the present and balance reality and ideal. In life, you should be proficient in one or two things, or cultivate some of your hobbies. Because when you do something seriously, you will have a "flow of heart", and a high degree of immersion can pull you back to the present and pay attention to the present.

　　Learn to rest, and don’t let the excited dopamine secrete constantly every day. From time to time, stealing laziness, taking a vacation and letting yourself relax can bring more opportunities for enjoyment. At the same time, it is recommended not to try multi-task parallelism. At present, with the development of mobile phones, computers and other communication equipment, office software is more and more "easy to use", and people often open multiple "windows" and carry out several tasks at the same time. People’s brains are getting busier and busier, and multithreading is an important reason why dopamine is out of control.

　　Speaking of which, I hope you can know something about dopamine. Perhaps, some people think that "dopamine wearing" is just a follow-up behavior of young people, but the deeper reason behind it is that people can get rid of their suppressed negative emotions and look for simple happiness. This summer, it is better to try "dopamine for one summer".

　　In December, the 56th issue of "Youth Learning Collection" focused on the supreme leader’s thoughts on the rule of law, and organized young members of the central and state organs to study deeply, have extensive exchanges and carry out various practical activities.

　　On December 26th, the Communist Youth League Working Committee of the central and state organs organized youth members from various departments to go to the Dongcheng District People’s Court in Beijing to conduct on-site centralized study and exchange. First of all, following the guidance of young commentators, everyone visited the exhibition on the theme of the governance of the source of litigation and the construction of the Party building team in Dongcheng Court, and felt the advanced working methods such as the "Harmony Cube" diversified dispute resolution mechanism initiated by Dongcheng Court around the theme of "justice and efficiency" and based on the judicial practice of faithfully performing its duties and serving the people. Later, I listened to a civil case trial, experienced the whole process of trial work in an immersive way, and felt the true feelings of justice for the people in a "zero distance". In the on-site exchange session, Ye Yanying, the person in charge of education, training and talent work, described the vivid practice of Dongcheng Court in thoroughly studying and implementing the supreme leader’s rule of law thought and supreme leader’s cultural thought, focusing on the trial work in the cultural field, actively creating a highland of characteristic talents and promoting the development of court culture in the new era. Roland, the pacesetter of the national court and vice president of the criminal trial court of Dongcheng Court, took the case of illegal one-day tour as the starting point, depicting the vivid image of people’s judges resolutely cracking down on illegal crimes and actively promoting socialist core values in judicial practice close to people’s lives and related to people’s interests. Fu Wen, vice president of the filing court, closely followed the court’s value function in realizing the judicial effect of "keeping the world safe by law and moistening people’s hearts by virtue", and deeply explained various relations that should be handled well in the process of judicial adjudication.

　　Everyone agrees that the Supreme Leader’s thought of rule of law is an important part of the Supreme Leader’s Socialism with Chinese characteristics Thought in the new era, and it is a solid theoretical basis and fundamental guiding ideology for comprehensively governing the country according to law, building a China ruled by law, and promoting a strong country ruled by law. Since the new era, the CPC Central Committee with the Supreme Leader as the core has coordinated the overall situation of the great rejuvenation strategy of the Chinese nation and the unprecedented changes in the world in the past century, drawn up a grand blueprint for comprehensively governing the country according to law, and started a new journey of comprehensively governing the country according to law, providing a solid guarantee of the rule of law for comprehensively promoting the great rejuvenation of the Chinese nation with Chinese modernization.

　　Everyone unanimously stated that, as a new force in practicing the first phalanx of "two maintenance", the youth of the central and state organs should thoroughly study and implement the supreme leader’s rule of law thought, take the lead in respecting the law, learning the law, abiding by the law and using it, strengthen the concept of governing the country according to law, effectively improve the rule of law thinking and ability to handle affairs according to law, enhance their self-confidence, confidence and determination in taking the road of Socialism with Chinese characteristics’s rule of law, and consciously become a firm believer, active communicator and model practitioner of the supreme leader’s rule of law thought.

　　"In the face of a common enemy, people who charge forward deserve respect". An internationally renowned epidemiologist praised China’s anti-epidemic feat in this way, which also represents the general consensus of the international community on "China’s sacrifice" and "China’s contribution".

　　COVID-19 epidemic is a major public health emergency with the fastest spread, the widest infection range and the most difficult prevention and control since the founding of New China. An important reason why China has been able to control the epidemic in a short time is that it has always been open, transparent and responsible to the world, so that the society can know and release the epidemic information in time. Report the epidemic situation to the World Health Organization at the first time, share the Covid-19 gene sequence with other countries in the world at the first time, publish the scientific research progress in medical journals at the first time, continuously update and publish the 7 th edition of COVID-19’s diagnosis and treatment plan and the 6 th edition of prevention and control plan, disclose the pathological anatomy results in time, and dynamically inform the vaccine development … … Some people say that China’s anti-epidemic progress has been exposed to the camera and basked in the Internet, which can be called "live broadcast" for the whole world.

　　One family in the world, love yourself and others; Feelings are like brothers, and the sun and the moon can be used as a mirror. On December 27, 2019, Zhang Jixian, a doctor at Hubei Hospital of Integrated Traditional Chinese and Western Medicine, reported three suspicious cases she had received for the first time; On December 30th, Wuhan Municipal Health and Health Commission issued the Emergency Notice on Doing a Good Job in the Treatment of Unknown Pneumonia. On December 31st, National Health Commission expert group arrived in Wuhan to conduct on-site investigation. From January 3, 2020, China began to formally inform the World Health Organization and other countries in the world, including the United States, of information in a timely and proactive manner … … From the discovery of cases to the response to the epidemic, every step taken by China is well documented and completely open. Some media commented that Wuhan’s "city closure" on January 23 shocked the world. If such a red warning still can’t wake you up, it only means that you are pretending to sleep. Bill Gates told the media many times that "China did a lot of right things from the beginning".

　　Covid-19 is a brand-new virus, which is called "the most cunning virus" by experts. It has the characteristics of strong concealment, long incubation period and many changes. It takes a process for human beings to understand and judge it. Any responsible country will not and should not rashly identify it without sufficient and effective evidence. There is no safe haven for infectious diseases, so it is impossible, unnecessary and even more forbidden for China to conceal or delay the epidemic. Since January, China experts have published more than 1,100 papers in English academic journals, and released the research results of epidemiological characteristics of COVID-19 to the international medical community without reservation; China has also opened an online knowledge center for COVID-19 epidemic prevention and control, which is open to all countries. These precious achievements at the cost of life have provided reference for countries to fight the epidemic and helped save thousands of lives around the world. "China’s generosity should be thanked by other countries", said Dino Patty, founder of Indonesian Foreign Policy Association. "The speed and thoroughness of China’s action surprised everyone", and the British newspaper The Guardian also praised the openness and transparency of China’s anti-epidemic information.

　　"In China, all deaths are tragedies, and all life is marked with the highest value," said an American lawyer. On April 17th, Wuhan announced the revised number of confirmed cases and deaths in COVID-19. At the early stage of the epidemic, due to insufficient admission capacity, overloaded hospitals, the failure of a few medical institutions to connect with the disease prevention and control information system in time, and some patients worried about going out for infection and seeking medical advice at home, some phenomena of late reporting, missing reporting, false reporting and repeated statistics were objectively caused, but there was never any concealment, and no one dared to bear the consequences of illegal concealment. Once the conditions for comprehensive verification were met, Wuhan conducted a comprehensive investigation, statistics and revision of epidemic data in time, which reflected a rigorous and scientific attitude towards history, people and the deceased.

　　Although rumors can confuse people for a while, justice will never be absent. Many countries and international organizations spoke highly of China’s anti-epidemic measures and transparency. Some media have asked, when Wuhan "closed the city", there were only a few confirmed cases abroad. How can you blame China for the spread of the epidemic? Anyone with a discerning eye can see that some western politicians are wantonly slandering and trying their best to vilify themselves and plant others. The World Health Organization has warned many times that the danger of slandering other countries and people is greater than the virus itself. As a matter of fact, the whole process of China’s anti-epidemic campaign has been made public, which is well known by the international community. What those who accuse China of "hiding" want to hide is what we really need to be vigilant.

　　There is no second earth where human beings can escape unscathed, and there is no independent parallel world. The materials donated by China enterprises to Italy are printed with the famous words of Seneca, an ancient Roman philosopher: "We are the waves of the same sea, the leaves on the same tree and the flowers in the same garden." This is a vivid portrayal of China’s practice of the concept of a community of human destiny with practical actions. It is urgent to fight the epidemic, and cooperation can win. China will always respect science, obey laws and respect practice, as always, open information, share experiences and strengthen cooperation, and urge all countries in the world to join hands and jointly safeguard the homeland of mankind.

　　　　　　 CCTV News:To pay attention to NATO’s space strategy. At the NATO defense ministers’ meeting held a few days ago, NATO adopted the first framework space strategy in history, and plans to officially launch the space strategy at the NATO summit scheduled for the end of this year, clearly listing space as a battlefield field alongside land, sea, air and network. Regarding the reasons for putting forward the space strategy, NATO officials once again talked about Russia, claiming that this is to cope with the growing space military strength of Russia and other countries.

　　　　　　 Reuters reported that NATO defense ministers reached an agreement at the Brussels meeting on June 26th and 27th, agreeing to formulate a space strategy. NATO member states will hold a meeting in London, England on December 3rd, when it will be officially recognized that member states can wage war not only in the fields of land, sea, air and network, but also in the field of space. The report quoted a senior NATO diplomat as saying: Although the relevant policies are still being discussed and formulated, the member States have basically reached a consensus on the decision to list space as a battlefield.

　　　　　　 In June 2018, NATO tried to launch a space strategy, but at that time it failed because of great differences between the parties, and finally released NATO’s first Joint Air Force Strategy. Some NATO member states believe that it is not cost-effective to promote the militarization of space. Trump’s previous announcement of the formation of a space force was opposed and criticized by the Pentagon and the US House of Representatives Armed Services Committee. If you follow the United States, it is likely that the loss will outweigh the gain.

　　　　　　 However, although NATO countries failed to reach an agreement on formulating a space strategy at that time, NATO’s "Joint Air Force Strategy" proposed that NATO should develop "Joint Air Force" in a "balanced and innovative" way, not only to continuously strengthen the anti-strike capability of space-based military facilities, but also to strengthen the utilization of these military facilities, which is the key goal of NATO’s future development. At that time, it was considered as a basic blueprint for NATO’s future development of space power.

　　　　　　 The U.S. government once threatened that the United States would occupy a "dominant position" in space, and other NATO countries flocked to it. Despite their differences, they still collectively please the United States. In the future, under the leadership of the United States, NATO may continue to further promote the militarization of space, so that "space NATO" can be transformed from a theoretical concept into a reality.

　　　　　　 But the United States must be clear that "absolute security" that cannot be achieved on land, sea and air will never be achieved in space. The absolute security sought by the United States simply does not exist, which will only further expand the strategic game and military confrontation with Russia into the space field, aggravate world turmoil, create more security dilemmas and bring more security risks. The "Star Wars" that once made human society shudder may become a reality in the future.

　　　　　　 Achieving win-win cooperation in the use of outer space is the general trend of the times. America’s military ambition in space can only be a poison to destroy peace and tranquility in outer space and ruin the original intention of outer space exploration. Whether other NATO countries continue to be at the mercy of the United States and play with fire, or focus on the general trend of the times and cherish peace, it is worth thinking twice.

　　After ideological baptism again and again, the vast number of party member cadres have returned to the original spirit, consolidated their foundation and cultivated their talents, constantly consolidated the ideological and moral foundation of being honest in politics, and built an ideological and moral defense line against corruption and change.

　　Only by strengthening our ideals and beliefs and constantly improving our political consciousness, ideological realm and moral level can we always be self-respecting, self-vigilant, self-motivated, cautious and cautious, and resist the temptation of corruption from the bottom of our hearts.

　　Fujian will build a digital modern exhibition hall and practice classroom, so that party member cadres can strengthen their sense of discipline in "seeing, listening, understanding and doing"; Shandong held Qilu Good Family Style Theme Exhibition to lead party member cadres to be the inheritors, leaders and guardians of excellent family style and clean family style; Xinjiang should tap the clean elements in the red resources and guide party member cadres to build the foundation of faith … … For some time, all localities have made great efforts to establish a solid foundation in combination with reality and innovative forms, and educated and warned party member cadres to be awe-inspiring, guard against fear and stick to the bottom line.

　　If you are afraid, you can stop saying and doing. Not long ago, the Political Bureau of the Communist Party of China (CPC) Central Committee held the 40th collective study on promoting "Don’t dare to rot, don’t rot and don’t want to rot" as a whole. General Secretary of the Supreme Leader systematically summarized the remarkable achievements and accumulated important experience of our party in the anti-corruption struggle from six aspects. One of the important aspects is: "building an ideological dam to resist corruption and change, strengthening the foundation with ideals and beliefs, arming the whole party with the party’s innovative theory, and strengthening the spirit with excellent traditional culture ‘ Calcium ’ , casting the mind firmly ‘ Soul ’ Build a strong ideological and moral defense line. " This requires the broad masses of party member cadres to strengthen their ideals and beliefs, strengthen their sense of purpose, firmly establish a correct world outlook, outlook on life and values, and consciously make up calcium and strengthen bones, build a solid foundation, and be virtuous and incorruptible.

　　The most important thing to keep the defense line against corruption and change is to keep the heart. Since the 18th National Congress of the Communist Party of China, the CPC Central Committee with the Supreme Leader as the core has closely integrated ideological party building with institutional party management, constantly set off a new upsurge of study and education within the Party, expanding from "key minority" to all party member, and extending from centralized education to regular education. The Party’s mass line education practice has enabled the cadres in party member to focus on "looking in the mirror, dressing properly, taking a bath and treating diseases", "three strictness and three realities" and "two studies and one doing" to bring strict party spirit exercise … … After ideological baptism again and again, the vast number of party member cadres have returned to the original spirit, consolidated their foundation and cultivated their talents, constantly consolidated their ideological and moral foundation of being honest in politics, and built an ideological and moral defense line against corruption and change.

　　Faith is crucial at all times. Belief in communism and Socialism with Chinese characteristics is the political soul of communist party people and the spiritual pillar for communist party people to stand any test. Without ideals and beliefs, there will be "calcium deficiency" in spirit and "rickets", which will inevitably lead to political deterioration, economic greed, moral degeneration and corruption in life. In real life, some cadres in party member are spiritually empty, demoralized and materialistic, and believe in money, fame and fortune, and pleasure. A few people even use the power given by the party and the people as a means to seek personal gain and fall into the abyss of corruption. In the final analysis, it is all caused by the vacillation of ideals and beliefs. Only by strengthening our ideals and beliefs and constantly improving our political consciousness, ideological realm and moral level can we always be self-respecting, self-vigilant, self-motivated, cautious and cautious, and resist the temptation of corruption from the bottom of our hearts.

　　The firmness of ideals and beliefs comes from the firmness of ideological theory. The Communist Party of China (CPC) people’s ideals and beliefs are firm because we are pursuing the truth, because we follow the law, and because we represent the fundamental interests of the overwhelming majority of the people. General Secretary of the Supreme Leader profoundly pointed out: "If you want to practice ‘ The indestructible body of King Kong ’ We must arm our minds with scientific theories and constantly cultivate our spiritual home. " The Supreme Leader’s Socialism with Chinese characteristics Thought in the New Era is contemporary China Marxism and 21st century Marxism, which is the essence of Chinese culture and China spirit, and has achieved a new leap in the China of Marxism. For the majority of cadres in party member, only by persistently arming their minds, guiding practice and promoting their work with Socialism with Chinese characteristics Thought of the Supreme Leader in the New Era, and integrating learning, thinking and application, and unifying knowledge, belief and practice, can they turn their learning achievements into unshakable ideals and beliefs, illuminate the road of struggle with the light of ideals and create a better future with the power of faith.

　　To consolidate the ideological and moral foundation of party member cadres’ incorruptible politics, we need to actively learn from the excellent incorruptible culture in Chinese history. From the method of being an official to "being clear, cautious and diligent", to the construction of family style, "don’t use the third master, waste your job and die"; From "don’t care about small things, you will eventually get great virtue" to "forbid those who are good at it, first forbid them before others" … … General Secretary of the Supreme Leader has repeatedly quoted the allusions of clean government culture, and provided spiritual nourishment for the cadres in party member with the excellent clean government culture that cherishes honor, pays attention to integrity and is clean and official. The majority of party member cadres should learn ideological nutrition from the excellent culture of clean government, inherit national character, practice new social practices, consciously be virtuous, strict in public morality, private morality, pay attention to conduct, integrity and heart-nourishing, and always keep the political nature of communist party people.

　　"Faith, faith and confidence are the best preservatives." Strengthening ideological and political construction to build a solid foundation of faith, improving party spirit consciousness and raising the sail of faith can inject strong ideological power into winning the tough and protracted anti-corruption struggle in an all-round way and build our party stronger.

In the last article, the design points and modules of the warehouse management system were introduced as a whole, but now this article will detail the design process from the actual design.

As mentioned before, warehousing mainly includes: purchase, transfer and return warehousing, while delivery includes sales and transfer delivery. Taking warehousing as an example, the status of each process in the design and the required information are introduced in detail below.

Procurement is mainly divided into three stages: before submission, after submission and receipt. At each stage, it is necessary to show their corresponding status, so that relevant personnel can monitor and track it in time.

Before submission:Filling in a purchase application usually contains a lot of goods. If you fill it out and don’t want to submit it for the time being, you need to provide a save-only function. The warehouse keeper can edit it next time and then submit it.

Application submission/review stage:Basically, there will be many warehouses in an enterprise, and the procurement is usually centralized and unified by a special department or personnel. Therefore, after the person in charge of each warehouse submits the purchase demand, there may be a review process. After the review is passed, the buyer will initiate the purchase from the supplier. Points to note are as follows:

• Need to consider the permissions between different roles, such as the permissions between the applicant and the reviewer and the page difference. Whether the warehouse and procurement are in the same system, if not, what data interaction and transmission are needed between the systems;
• After the buyer submits the application, whether it is necessary to make a message notice to remind the auditor to review it in time, or whether it is necessary to directly display the contact information of the auditor on the page, and whether it is possible to contact the auditor directly if the purchase order is in a hurry;
• Whether it is necessary to provide an entrance for re-application when the application is rejected;
• In the process of approval, what values need to be filled in by the auditor, what values can be modified, and what values need to be returned to the applicant after modification;

Waiting for receipt: In this state, whether to return goods and whether to need logistics information depends on the demand;

Confirm receipt:After the arrival of the goods, it is necessary to confirm the receipt of the goods, which means that the purchase is completed.

• Receiving goods in batches:When filling in the purchase order, many goods may be filled in, and the quantity will be relatively large. However, in actual delivery, the goods may be delivered separately, which requires support for receiving goods in batches.
• Not arrived/out of stock:At the time of receiving goods, there may be some goods missing, which needs to be marked at the time of receiving goods in order to continue tracking. At this point, you need to consider the possible operations in actual business operations, such as the next replenishment or direct refund, or other circumstances. No matter what kind of operation, you need to have an operation record or explanation to facilitate financial reconciliation;
• Attachment information:When receiving the goods, consider whether it is necessary to upload some document pictures as the receipt voucher. (depending on the needs of relevant departments)

Refers to the information that needs to be displayed on the purchase order, mainly including commodity information, relevant personnel and required number. (depending on the business)

What specific states will exist depends on which warehouse is the initiator.

• The initiator is the receiving warehouse: similar to the above procurement process, it still needs approval and receiving status;
• The initiator is the delivery warehouse: the warehousing warehouse only needs to wait for receipt directly, and it is not necessary to display the status before receipt;

In addition to the information mentioned in the purchase, it is also necessary to indicate the delivery warehouse.

Under normal circumstances, this kind of situation is a return application initiated by the buyer, but in the warehouse management system, we only need to be able to monitor whether the goods have been delivered and wait for receipt.

It mainly includes sales order information, related time information and return refund information.

In the actual warehouse management system, different enterprises will have different business processes, and the system will change accordingly.

• Purchase method 1:Set up a large warehouse as a stocking warehouse (whether it is a physical warehouse or a virtual warehouse. Of course, considering the logistics cost, the general goods will not be transported to the physical warehouse first, but only a virtual warehouse will be set up to manage the inventory of the stocking warehouse. When the local warehouse needs goods, it will be delivered directly from the supplier. When the small warehouses around the country need goods, they will get the goods directly from the stocking warehouse (the goods mentioned here are limited to the increase or decrease of the inventory). In this case, the administrator of the large warehouse is responsible for what kind of goods to purchase from suppliers and how much to purchase, and the person in charge of the local warehouse only needs to submit the demand;
• Purchase method 2:There is no stock warehouse. When the local warehouse submits the demand, the purchaser will place an order with the supplier to purchase.

The difference between the two methods lies in whether it is necessary to place an order with the supplier in advance to purchase the goods. Of course, for the person in charge of the local warehouse, there is not much difference between the two methods in operation.

In addition, many enterprises not only have warehouses for retail, but also warehouses dedicated to mass sales. Some may be combined and managed together, while others will be specially distinguished. There is also how to deal with special goods such as gifts and gifts, which also need to be considered.

In a word, the function and process of the system need to be decided according to the business process.

Welcome to add!

Backstage system: inventory management system

Only in May, this year’s achievements in the film and television industry have reached a very high level. At the beginning of the year, The Knockout triggered an upsurge of "soaring" for everyone, and it was no exaggeration for the whole people to pursue dramas. The final Douban score was also fixed at 8.5, in addition to 8.7 "Three-body" and 8.1 "Thirteen Years of Dust". I thought it was enough for a hundred flowers to blossom, but I didn’t expect the Long Season to come.

This work, which was directed by Xin Shuang and brought together three heavyweight actors, Fan Wei, Qin Hao and Chen Minghao, was not enthusiastic when it was first broadcast, and even had a faint tendency to jump on the street. However, although it is a small audience, this part of the audience has given a very high evaluation. Under the promotion of the "tap water" audience, "Long Season" really bloomed!

Two days ago, at the end of the TV series, Douban scored 9.5 directly, and turned over the leaderboard. The same score was also "Parents Love" and "Bright Sword". This comparison is enough to show the satisfaction of the audience. With the gradual easing of the heat, the score of the play has dropped slightly. At present, it has dropped by 0.1 points, and it is estimated that it will eventually fall to around 9.2, which is still far behind.

Looking out Xin Shuang’s Hidden Corner, the score of Douban is 8.8. After three years, the score of Xin Shuang’s new work is about 0.5 higher, which is really shocking. We still remember those hot topics when "Hidden Corner" was broadcast, such as "Climbing the Mountain with Qin Hao", bald modeling, and the friendship of the young iron triangle. We can still hear the nursery rhyme "Little White Boat" with goose bumps all over the floor.

The unique audio-visual language is the biggest feature of Xin Shuang’s works, which is particularly prominent in The Long Season. The first is the director’s intention praised by the audience-the beginning and end of each episode are surprising, especially at the end, Xin Shuang can always find music that fits the story strangely.

After Shen Mo went to Wang Yang’s appointment to see Titanic, but Wang Yang stood her up and watched the movie alone, she walked out of the cinema, and the sullen uncle Shen Dongliang stood at the door. This episode ended here, and the ending song followed, which turned out to be twinkling star.

But where did the stars come from? Shen Dongliang’s shadow is stretched under the street lamp, reaching to the foot of Shen Mo. Where can you see the stars under this haze? Xin Shuang’s use of this song here may be a foil to Shen Mo’s dark life.

Perhaps further thinking, why use a nursery rhyme? Childhood, how did Shen Mo spend his childhood? At the age of 9, she was adopted by Shen Dongliang and raised this girl like a preserve. I don’t know when my dirty hands reached into my collar. Shen Mo’s childhood may be playing this song with the piano bought by Shen Dongliang over and over again, enduring the darkness and longing for his own starlight.

There are many classic tracks in the play. The Moonlight by Debussy is what Shen Mo has been playing, and the Blue Danube by Strauss is what he dumped the body behind. With a beautiful waltz in such a cold and bloody picture, the violent picture is drawn, and Xin Shuang understands the beauty of the film!

In the scene of Qin Haoling’s box lunch, the car rushed into the river, Gong Biao held the lottery ticket in his hand, and the string of lottery numbers was still in his ear, so he fell into the water with a smile. I have bought countless lottery tickets, perhaps this is the most unexpected one, but it happened that this time I won the lottery, and it happened that this accident happened. When the music started, it was Joyside’s If There is A Tomorrow. A rock song was used here, which was a bit absurd but quite appropriate.

Xin Shuang chose this song for another reason, that is, he used to be the guitarist of Joyside. Although he left the band in 2006, his attitude towards Joyside and rock and roll remained unchanged. He loved and used these songs. There are also works by singers and bands such as Frog Pool, Supermarket and Past Life in the play. Xin Shuang is familiar with rock music, and every soundtrack hidden in his favorites is as ingenious as a pen.

Now "The Long Season" has come to a close, but the attraction of high scores and the evaluation of the audience who have seen it are doomed that this drama will not sink, but will only be seen by more people, unconventional and not sensational. It is obviously suspense but makes people laugh and cry. "The Long Season" deserves all achievements!

　　[Shaanxi: rainstorm yellow warning issued to guard against disasters such as landslides and mudslides]

　　According to China Weather Network, a new round of heavy rainfall began in Shaanxi on the night of July 1st. In the next three days, the rainfall in Shaanxi will continue, with heavy rainfall mainly concentrated in Hanzhong, Ankang, Shangluo and other places, with heavy rain and heavy rain in some areas. In response to the rainfall process, Shaanxi Meteorological Bureau has launched a three-level emergency response to heavy rain, and all localities need to guard against secondary disasters such as landslides and waterlogging.

　　Shaanxi Meteorological Observatory issued a yellow rainstorm warning at 10: 00 on July 2: Due to the influence of vortex shear, more than 100 mm of precipitation has appeared in the southeast of Hanzhong from 09: 00 on July 1 to 09: 00 on July 2.

　　It is estimated that there will still be more than 50 mm precipitation in Hanzhong area, western Ankang, western Shangluo and southern Guanzhong from day to night on July 2, and the local area in southern Hanzhong can reach more than 100 mm. Heavy precipitation affects regional geological disasters such as landslides, mudslides and collapses, and the meteorological risk level of mountain torrents and floods in small and medium-sized rivers is high.

　　[The high temperature in North China is temporarily suspended and Jiangnan continues to be sunny and hot on the 3 rd]

　　According to China Weather Network, the range and intensity of high temperature in China continued to shrink yesterday, and Beijing, Tianjin, Shijiazhuang and other cities in North China have got rid of high temperature. Today, the high temperature in North China has temporarily subsided, but it is only one or two days apart, and then the high temperature will increase again. Like Beijing, Shijiazhuang and other places, the temperature dropped briefly on Monday and Tuesday, and the high temperature reappeared on Wednesday and Thursday, and the summer heat was hard to disappear.

　　The high temperature in the south is also suppressed first and then raised. Yesterday, the high temperature area in the south of the Yangtze River was reduced to the minimum in that week. Starting today, with the weakening of rainfall, the high temperature in the south of the Yangtze River has developed again. On the 3rd, Jiangxi and the central part of Hunan were sunny and the temperature climbed rapidly. On the 4th, with the strengthening of subtropical high, there will be a wide range of high temperature weather, and Jiangnan area will also be the "main battlefield" of high temperature for some time to come.

　　Cctv newsTen days ago, earthquakes of magnitude 7 and 6.6 occurred in Jiuzhaigou, Sichuan and Jinghe, Xinjiang, respectively, causing casualties and property losses. Are there any effective ways to reduce casualties and property losses caused by the earthquake? The answer is yes. The reporter recently learned from the Fourth Academy of Aerospace Science and Technology that an earthquake-proof "artifact" was successfully developed in 41 institutes of the Institute.

Illustration: The anti-seismic effect of traditional anti-seismic technology and fake bearing after earthquake isolation.

　　The traditional anti-seismic technology is to firmly connect the superstructure and foundation of a building, so that the earthquake energy can still vibrate and deform the structure after being transmitted to the superstructure, and when the force exceeds the strength of the building structure, it will be destroyed or even collapsed.

　　The isolation technology refers to setting isolation layer between the superstructure and foundation of the building without changing the original architectural design scheme, that is, placing rubber isolation bearings. The vertical bearing capacity of the isolation layer is large, but it is soft in the horizontal direction. When the earthquake comes, it can isolate about 80% of the energy of the earthquake, which can effectively reduce the deformation caused by the acceleration response of the upper structure of the building caused by the earthquake, thus reducing the damage to the building caused by the earthquake.

　　Since 2014, the Ministry of Housing and Urban-Rural Development has issued a document stating that the housing and urban-rural construction departments of all provinces and autonomous regions need to promote the application of seismic isolation technology in an orderly manner to ensure the quality of the project. Subsequently, Gansu, Xinjiang, Qinghai and other high-intensity areas made it mandatory. All high-intensity areas with seismic fortification intensity of 8 degrees or above and 4-12-story school teaching buildings, student dormitories, hospital medical rooms, kindergartens, airports and other crowded public buildings rebuilt after the earthquake must be designed with base isolation technology. At present, about 7 billion square meters of building area under construction in China need to use seismic isolation equipment.

　　After more than two years’ research, the 41 Institute of the Fourth Academy of Aerospace Science and Technology has successfully developed a laminated rubber isolation bearing, which is made up of a layer of steel plate and a layer of rubber, and the rubber and steel plate are firmly bonded together after processing, with sufficient rigidity and vertical bearing capacity, small horizontal rigidity and large horizontal deformation capacity.

　　"The products developed by 41 are in strict accordance with the national standards, fully combined with the design technology and process technology of flexible joints of solid rocket engines, and have their own characteristics. The overall indicators of the products are at the same level as those of similar domestic products. The series of products have passed the type inspection of isolation products designated by the state in Huazhong University of Science and Technology, and have fully met the market demand." Introduction of 41 scientific researchers from the Fourth Academy of Aerospace Science and Technology.

　　It is reported that the design method, rubber material, adhesive, molding process, process control and product performance of this isolation bearing have been improved due to the guarantee of aerospace technology, which can ensure that the vibration period of the building is extended by 2-3 seconds or more, thus avoiding greater damage caused by co-frequency resonance. At the same time, the bearing also has proper damping and stable elastic reset function, as well as good durability and fatigue resistance.

　　The researchers said that due to the optimization technology and molding control method of military products, the individual indicators and product quality reliability of this isolation bearing are better than those of similar domestic products. "However, due to the late start, there is still a gap between China and Japan, the United States and European countries in the field of seismic isolation products, especially the series of large-diameter products over 1.5 meters is still blank. These directions are also the direction of our follow-up efforts."

　　In 2017, in the "Shaanxi Youth Scientific and Technological Achievements Transformation Promotion Conference", the newly developed isolation bearings were selected into 22 integration of defense and civilian technologies projects screened and released by Shaanxi Province.
