The second Room N incident broke out at Seoul National University in South Korea. According to South Korean media reports on May 22, as of now, as many as 61 female victims have been confirmed, including 12 students at Seoul National University.

The Seoul Police Department has so far arrested five gang suspects, two of whom are graduates of Seoul National University. They are suspected of making and privately spreading them on the instant messaging software T from July 2021 to April this year. Pornographic photos or videos synthesized using deep counterfeiting technology.

According to the police, in the process of arresting the main offender Park, the private reporting group Tracking Group Sparks, which first reported the incident in Room N five years ago, provided decisive assistance. Yuan Enzhi, who was in the pursuit team, disguised himself as a male, entered the private live broadcast room to lurk for two years, and contacted Park. This year, he lured Park to meet offline to help the police successfully capture him.

According to Agence France-Presse reported on May 22, former U.S. President Trump claimed on the 22nd that the FBI’s 2022 search warrant for his Florida home showed that Biden wanted his life, which aroused people’s doubts and also attracted some people’s support.

Reported that his inflammatory remarks were made after court documents outlining the federal police search plan were made public. Trump has been charged with negligent handling of confidential documents that were discovered at his residence in Mar-a-Lago, Florida, after he left the White House.

Court documents include standard FBI language that states FBI agents have the right to use lethal force if a person is in imminent danger.

But Trump, who will face Biden in the November presidential election, said the wording showed agents were prepared to shoot him and hurt his family.

According to U.S. media reports, Trump said in an email calling for donations: It has just been disclosed that Biden’s Justice Department was authorized to use lethal force to conduct a despicable raid on Mar-a-Lago Manor. You know, they’re eager to do something incredible

Trump said in an email: Joe Biden is going to draw a gun to get rid of me and put my family in danger. He thinks he can scare me, intimidate me, and knock me down!

Reported that this is Trump’s latest accusation against his Democratic opponent. He repeatedly claims without evidence that Biden is using justice against him.

Senate Democratic Leader Chuck Schumer called on all elected representatives to condemn Trump’s strange and dangerous remarks. He said: We cannot let this person, Donald Trump or anyone else, throw a match like this and ignite the flames that could devour our democracy.

Republican Liz Cheney, who is Trump’s main opponent, believes Trump is unstable. However, Marjorie Taylor Green, a staunch supporter of Trumpism, believes that the Justice Department and the FBI gave Trump the green light to murder.

Trump was not in Florida on the day of the search. In a rare statement, the FBI assured that the matter did not deviate from standards. (Compiled by Liu Zhuo)

It is not only related to the smooth progress of transactions, but also directly affects the capital flow and risk control of enterprises. When sofa covers are imported goods, understanding and choosing the right payment method is key. As a professional sofa cushion manufacturer, our company also needs to conduct in-depth discussion and selection of payment methods in the process of importing sofa covers.At the same time, quilt manufacturer It is no longer a relatively unfamiliar industry, and it enters the public’s sight more and more frequently, gaining more attention and recognition. https://www.jopalic.com/

　　

　　Jopalic.com | Discussion on the payment method of imported sofa Covers

　　

　　1. the importance of the payment method of imported sofa covers

　　

　　The import of sofa covers involves transnational transactions, and the reasonable choice of payment methods can ensure the safe and efficient conduct of transactions. On the one hand, appropriate payment methods can protect the rights and interests of importers and avoid losses due to supplier defaults or quality problems. For sofa cushion manufacturers like us, the quality of imported sofa covers is directly related to the quality of our final products, so choosing a reliable payment method is particularly important. On the other hand, it can also provide certain guarantees for suppliers and promote the cooperation between the two sides. At the same time, different payment methods will have different impacts on the fund flow of enterprises. Reasonable selection of payment methods can optimize the fund management of enterprises and improve the efficiency of fund use. As a manufacturer, we need to ensure the rational use of funds to ensure the continuation of production and the stable development of the enterprise.

　　2, the common payment method of imported sofa cover

　　

　　Payment by letter of credit

　　

　　(1) Definition and process

　　

　　A letter of credit is a written document issued by a bank to an exporter as a conditional promise of payment at the request of the importer. When importing sofa covers, our company, as an importer, first applies to the issuing bank to open a letter of credit, and after the bank is approved, it will send the letter of credit to the notifying bank in the country where the exporter is located. After receiving the L/C, the exporter shall deliver the goods in accordance with the L/C and submit the relevant documents to the advising bank. Inform the bank to check the documents and send them to the issuing bank. After the issuing bank checks the documents to be in accordance with the L/C requirements, it will pay to our company and we will collect the goods against the documents.

　　

　　(2) Advantages

　　

　　 High security: Due to the involvement of the bank, the letter of credit payment method provides a higher security for importers like us. As long as the documents submitted by the exporter meet the requirements of the L/C, the bank must pay, thereby reducing our risk. For our company, this means that the payment will be made on the premise of ensuring that the quality and quantity of sofa covers meet the requirements, which guarantees our interests.

　　

　　 Guarantee the quality of the goods: In order to receive the payment for goods smoothly, the exporter usually provides the goods and related documents that meet the quality standards in accordance with the requirements of the letter of credit, which ensures the quality of the goods to a certain extent. As a sofa cushion manufacturer, we have high quality requirements for sofa covers, and L/C payment can prompt suppliers to provide high-quality products.

　　

　　(3) Disadvantages

　　

　　 Complicated procedures: Opening a letter of credit needs to go through a number of links, including application, review, notification, presentation, etc., the procedures are more complicated, and the cost is relatively high. This may increase transaction costs and time costs for our company.

　　

　　Poor flexibility: Once the terms of the letter of credit are determined, it is difficult to modify and lack flexibility. If special circumstances arise in the course of the transaction, the terms of the letter of credit need to be changed, which may cause the transaction to be delayed. In our production process, it may be necessary to adjust the specification and quantity of sofa covers due to changes in market demand or the adjustment of production plan, and the letter of credit payment method may bring some inconvenience at this time.

　　

　　Payment by collection

　　

　　(1) Definition and process

　　

　　Collection refers to a settlement method in which exporters entrust banks to collect payment from importers. When importing sofa covers, the exporter, after shipping the goods, draws a bill of exchange together with the shipping documents to the collecting bank, and entrusts it to collect the money from our company. The collecting bank sends the documents to the collecting bank in the country where our company is located, and the collecting bank presents the documents to us. After checking the documents, our company can choose to redeem or D/A. If you choose the payment order, we can obtain the documents to collect the goods after payment; If D/A is chosen, we can obtain the documents after acceptance of the draft and pay for the goods when the draft maturates.

　　

　　(2) Advantages

　　

　　 The procedure is relatively simple: compared with the payment by letter of credit, the procedure of payment by collection is relatively simple, and the cost is relatively low. For our company, it can reduce transaction costs and improve transaction efficiency.

　　

　　 It is more favorable to the importer: in the case of documents against acceptance, our company can obtain documents to extract the goods without paying for the goods, which is conducive to capital turnover. As a sofa cushion manufacturer, we can first put the sofa cover into production, and then pay for the goods after the product is sold, which relieves the financial pressure.

　　

　　(3) Disadvantages

　　

　　 Greater risk: under the collection payment method, the bank only acts in accordance with the exporter¨s mandate and does not assume the payment responsibility. If our company refuses to pay or accept, the exporter may face the risk that the payment will not be recovered. Similarly, if the quality of the goods supplied by the exporter is not up to the requirements, we may also face losses.

　　

　　 Lack of constraints: For our company, due to the lack of strict constraints of the bank, there may be delays in payment or non-payment. This may affect our relationships with suppliers and is not conducive to long-term development.

　　

　　Payment by remittance

　　

　　(1) Definition and process

　　

　　Remittance means a settlement method by which our company remits the payment of goods to the exporter through the bank. When importing sofa covers, we can choose to pay the exporter by T/T, M/T or D/D according to the contract. Telegraphic transfer is the most commonly used method of remittance. Our company issues telegraphic transfer instructions through the bank to remit the payment to the bank account designated by the exporter. After receiving the payment, the exporter will ship the goods to our company.

　　

　　(2) Advantages

　　

　　 Simple procedures: The procedure of remittance payment is the most simple and the cost is the lowest. For enterprises like us, it can save transaction costs and improve transaction efficiency.

　　

　　Speed: Telegraphic transfer can usually complete the transfer of funds in a short period of time, which is conducive to the rapid progress of transactions. In our production process, if we need to import sofa covers urgently, the remittance payment method can meet our needs.

　　

　　(3) Disadvantages

　　

　　 Big risk: the remittance payment completely depends on the credit of our company, once we breach the contract, the exporter will face the risk of being unable to recover the payment. This is a big risk for exporters and may cause them to be reluctant to work with us.

　　

　　(2) Lack of protection: Compared with letter of credit and collection payment methods, remittance payment methods lack bank protection, which is disadvantageous to exporters. Similarly, for our company, it is difficult for us to defend our rights and interests if the exporter does not deliver the goods on time or the quality is not up to requirements.

Beijing, March 13 (Xinhua)– six more countries! The expansion of visa-free moments sends a strong signal of China’s opening up.

Reporter

Starting from March 14, China will try out the visa-free policy for ordinary passport holders in Switzerland, Ireland, Hungary, Austria, Belgium and Luxembourg. This is another expansion of China’s visa-free circle of friends following the formal entry into force of the China-Thailand visa abolition agreement on the 1st of this month.

According to the relevant arrangements, people from Switzerland and other six countries who hold ordinary passports to China for business, sightseeing, visiting relatives and friends and transit for no more than 15 days from March 14 to November 30 in 2024 can enter China visa-free. People from the above-mentioned countries who do not meet the visa-free conditions are still required to apply for a visa to come to China before entering the country.

As of early March, China had concluded visa abolition agreements covering different passports with 157 countries and reached visa simplification agreements or arrangements with 44 countries. Including Singapore, Antigua and Barbuda and Thailand, which have signed visa abolition agreements with China since the beginning of this year, 23 countries have implemented comprehensive visa abolition arrangements with China. In addition, more than 60 countries and regions have granted Chinese citizens visa-free or visa-on-arrival treatment.

Leon, a Swiss businessman, runs a tourism service in Geneva and has many Chinese partners. He said that after China’s visa-free entry into force for Switzerland, it will be more convenient to visit friends or discuss cooperation in China. I believe there will be more Swiss like me, planning to go to China for a visit.

For some time, the Chinese side has continuously introduced a number of visa optimization measures to come to China, including reducing the contents of visa application forms, reducing visa fees in stages, simplifying the examination and approval procedures for studying in China, exempting some applicants from fingerprints, visa-free appointments, and trying out visa-free policies for some countries, to further solve the difficulties and congestion points of foreigners coming to China.

During the Spring Festival this year, the number of inbound tourists from China reached 3.23 million, and the number of visa-free tourists from France, Germany, Malaysia and Singapore increased significantly, and the total number of inbound travel orders from these countries doubled compared with the same period in 2019.

The Chinese side also continues to launch a series of practical measures to make life convenient for foreigners and make them feel at home.

In order to better meet the diversified payment service needs of groups, including foreign visitors to China, the “opinions on further optimizing payment Services to enhance payment convenience” was officially released on March 7. a series of requirements are put forward in improving the environment for accepting bank cards, continuously optimizing the environment for the use of cash, and improving the convenience of mobile payment.

In addition, in view of the practical problems encountered by foreign visitors in using mobile payment, the people’s Bank of China instructs Alipay and Tenpay to optimize their business processes, improve the efficiency of binding overseas bank cards, and simplify identity verification arrangements while effectively protecting the security of personal information. Major payment institutions are instructed to raise the limit of individual transactions for foreign visitors to China to use mobile payments from US $1000 to US $5000, and the annual cumulative transaction limit from US $10,000 to US $50, 000.

In various scenes that are closely related to people’s lives, such as food, housing, transportation, travel, shopping, entertainment, and medicine, the small move of getting through the last kilometer one by one reflects the consideration of constantly improving the level of international service and promoting people-to-people exchanges between China and foreign countries.

Continuously improve the convenience of Chinese and foreign personnel exchanges and foreign personnel in China, taking into account the actual needs of people in Sino-foreign exchanges, has a strong realistic pertinence, but also in line with the trend of world integration and development. Su Xiaohui, an associate researcher at the China Academy of International Studies, said that the release of these good news and the acceleration of related work once again demonstrated China’s posture and sincerity in strengthening opening up and cooperation.

At the just-concluded national two sessions, China announced to the world a series of practical measures to promote high-level opening up to the outside world and strengthen international exchanges and cooperation.

We will step up efforts to attract foreign investment, promote the implementation of the eight actions to support high-quality co-building of Belt and Road Initiative, and do a good job in international cooperation platforms such as the entry Expo, the Service Trade Fair, the Consumer Expo and the chain Expo. In the bright picture of holding the new session of the Forum on China-Africa Cooperation hand in hand and mutual benefit, the cake of cooperation between China and the rest of the world is bound to grow bigger and bigger.

Yang Mingjie, director of the China Institute of Modern International Relations, said that in the context of the weak global economic recovery, instability and uncertainty, the strong signal of openness and cooperation sent by China has injected more momentum and valuable certainty into promoting the common development of the world. The relationship between China and the world market will be closer and colorful.

Over the past few days, international media and scholars have expressed their confidence in the prospects of China’s opening up and development: China’s further opening up to the outside world provides growth opportunities for global partners and China’s new development provides new opportunities for the world. This is in line with the strong desire of the people of all countries for peaceful development.

Starting from spring, a vibrant China will write more wonderful stories about blending with the world and achieving each other. (reporters Wang Bin, permit, Shi Jingnan, Ren Qinqin, Zhu Chao, Wu Yue)

Beijing, July 17: An international study recently found that in January, when the Antarctic summer temperature is the highest, 57% of the melt water on the Antarctic ice shelf exists in the form of snow and mud. However, under normal circumstances, regional climate change models do not include This part of the melt water is calculated. This means that the amount of melt water on the Antarctic ice shelf is much higher than previously predicted.

Researchers from the University of Cambridge and other institutions in the United Kingdom published an article in the latest issue of Nature Geoscience that they trained machine learning models to analyze the monthly surface melt water records of 57 Antarctic continental ice shelves between 2013 and 2021. As well as mapping the snow and mud of the Antarctic ice shelf, it was found that in January, when the temperature in the Antarctic summer was the highest, 57% of the melt water on the Antarctic ice shelf existed in the form of snow mud, which is, snow soaked in water. The rest of the meltwater exists in surface ponds and lakes.

Researchers said that people usually use satellite images to map meltwater, but from the images, only meltwater lakes, etc. can be identified with the naked eye, and snow and mud are difficult to identify because it looks like the shadows of clouds. Machine learning models can use more satellite information such as light wavelengths to determine which areas are named snow and mud, making it possible to more accurately measure the amount of water melted on the ice shelf.

The study found that in the five major ice shelf areas, the amount of water melted on the Antarctic ice shelf caused by surface melt water was 28 times higher than predicted by standard climate models.

The surface melting of the Antarctic ice shelf mainly occurs in the summer of the southern hemisphere. Whether it is slush or melt water existing in surface ponds or lakes, it will affect the stability of the ice shelf and lead to sea level rise.

Geneva, March 14: Ambassador Chen Xu, Permanent Representative of China to the United Nations Office at Geneva and other international organizations in Switzerland, delivered a joint speech on behalf of 80 countries at the 55th session of the United Nations Human Rights Council on the 14th on artificial intelligence to promote children’s rights.

Joint speeches pointed out that artificial intelligence is the name of a new field of human development, and should adhere to the concept of extensive consultation, joint contribution and sharing, and work together to promote artificial intelligence governance. Children are the future and hope of mankind. The new generation of children has become one of the main groups using artificial intelligence technology and enjoying artificial intelligence.

Joint speakers emphasized that children’s mental health issues are crucial. The joint speech called for promoting the high-quality development of artificial intelligence, helping to promote children’s mental health, and protecting children’s rights.

They spoke together and put forward three propositions. The first is to adhere to child-oriented principles, uphold artificial intelligence for children, and give full play to the important role of artificial intelligence in guiding children’s mental health. The second is to adhere to fairness and universal benefits, strengthen exchanges and cooperation, provide technical support, share experiences and good practices to developing countries, and bridge the smart divide. The third is to adhere to harmony without difference, respect the sovereignty, laws, national conditions and historical, religious and cultural backgrounds of each country, and strengthen international artificial intelligence governance on this premise.

This is one of a series of speeches initiated by China at the Human Rights Council on artificial intelligence to promote the rights of specific groups, and has received widespread support and praise from Member States of the United Nations. China once launched a joint speech on artificial intelligence to promote the rights of people with disabilities at the 53rd session of the Human Rights Council.

Good storage management can ensure that the goods are not damaged, lost or stolen during storage, ensuring the safety of the goods. For example, when the goods are stored in the warehouse, carefully check the package. If any damage is found, reinforce or replace the package in time to prevent the goods from being damaged due to packaging problems during storage.

　　

　　Optimize inventory management

　　

　　Reasonable storage management can help enterprises accurately grasp the inventory situation and avoid the occurrence of inventory overhang or out of stock. Through the effective control of inventory, enterprises can reduce inventory costs and improve the efficiency of capital use. For example, the inventory management system is used to classify statistics on different specifications and styles of sofa covers, and real-time monitoring of changes in the number of stocks in order to adjust procurement and sales strategies in a timely manner.

　　

　　Improve logistics efficiency

　　

　　Efficient warehouse management can make the goods more smooth in and out of the warehouse, reduce the waste of time in the logistics link. At the same time, reasonable storage layout and goods placement can improve the space utilization rate of the warehouse and improve the efficiency of logistics operations. For example, sofa covers of common specifications are placed close to the delivery area to facilitate quick picking and delivery, reducing the distance and time of cargo handling.

　　

　　Meet customer needs

　　

　　Timely and accurate delivery is the key to meeting customer needs. Good warehouse management can ensure that goods are delivered within the time required by customers and improve customer satisfaction. For example, the establishment of a rapid response delivery mechanism, when receiving customer orders, can quickly and accurately find the corresponding goods and packaging and delivery.

　　Warehouse location

　　

　　(1) Geographical location

　　

　　The geographical location of the warehouse should be selected in a place with convenient transportation and close to the port or airport, so as to facilitate the transportation and loading and unloading of goods. At the same time, we should consider whether the surrounding logistics supporting facilities are perfect, such as road conditions, parking lots, gas stations, etc. For example, if the road around the warehouse is spacious and flat, it is easy to enter and exit large trucks, which can greatly improve the efficiency of goods transportation.

　　

　　(2) Warehouse area

　　

　　According to the business scale and development needs of the enterprise, choose the appropriate area of the warehouse. The warehouse area should be able to meet the current inventory needs, and leave some room for expansion. At the same time, it is necessary to consider the height of the warehouse, column distance and other factors to ensure that the space can be fully utilized. For example, for higher warehouses, high-rise shelves can be used to increase vertical storage space.

　　

　　(3) Environmental conditions

　　

　　The environmental conditions of the warehouse should meet the storage requirements of the sofa cover. For example, the warehouse should be kept dry and well ventilated to avoid damage to the goods caused by humidity, high temperature, direct sunlight, etc. For some special materials of sofa covers, such as silk, wool, etc., it is also necessary to consider the temperature and humidity control of the warehouse. Temperature and humidity monitoring equipment can be installed in the warehouse to monitor environmental changes in real time, and take timely measures to adjust once it exceeds the set range.

　　

　　Warehouse layout and planning

　　

　　(1) Functional area division

　　

　　According to the operation process and functional requirements of the warehouse, reasonably divide different functional areas, such as receiving area, storage area, shipping area, return area, office area, etc. A reasonable channel width should be maintained between each functional area to facilitate the handling of goods and the passage of personnel. For example, the receiving area should be located near the warehouse entrance to facilitate the receiving and inspection of goods; The delivery area should be close to the exit to facilitate the quick loading and delivery of goods.

　　

　　(2) Shelf and space planning

　　

　　Select the appropriate shelf type and storage space planning method to improve the space utilization rate of the warehouse and the storage efficiency of goods. For the large volume and light weight goods such as sofa covers, light shelves or attic shelves can be used. At the same time, the cargo location should be numbered and identified to facilitate the search and management of the goods. For example, on the shelf affixed a clear location label, indicating the name of the goods, specifications, batches and other information, so that warehouse managers can quickly and accurately find the required goods.

　　

　　(3) Channel design

　　

　　Rationally design the channel of the warehouse, including the main channel, the sub-channel and the channel between the shelves. The width of the channel should be determined according to the handling equipment and operation process of the goods to ensure that the goods can smoothly enter and exit the warehouse. For example, the main passageway should be wide enough for handling equipment such as large forklifts to pass freely; The aisle between the shelves should be convenient for manual handling of goods, and the width should not be too narrow.
