Affected by the epidemic, the development of foreign trade is facing great challenges. While continuing to explore the international market, many foreign trade enterprises are generally optimistic about the potential of the domestic market and begin to put marketable export products into the domestic market.
Recently, the reporter walked into the park of Ganzhou Aoketai Tool Technology Co., Ltd., and saw that the blades in the workshop were neatly arranged on the production line, and the processes of mold calibration, surface grinding, coating and polishing were orderly. After customs inspection, these products can be packed and shipped to the domestic market for sale.
Aoketai Company is one of the fast-developing precision metal tool manufacturers in China and one of the major tool export enterprises in Jiangxi. Besides domestic sales, products are also exported to Spain, Germany, Poland and other countries.
"Affected by the epidemic, the sales of our products in the European and American markets have been greatly impacted. At the same time, domestic tool importers have turned to domestic tools in the context of the domestic cycle. We want to take this opportunity to make the domestic market bigger and stronger and stabilize production and operation." The person in charge of the enterprise said, "Comrades from the Customs took the initiative to come to our door, explained the technical and trade policies to us, instructed us to produce products of the same line, the same standard and the same quality that can be exported and sold domestically, and also preached the policies related to tax reduction and exemption, and taught us how to prepare the application materials, which helped us save a lot of money. With such a’ family’, we are full of confidence and expectation for the future development. "
In order to promote the development of emerging industries and high-tech industries in southern Jiangxi Soviet area, Ganzhou Customs, a subsidiary of Nanchang Customs, has tailored a number of assistance measures in combination with industrial characteristics, and constantly explored the supervision service mode of high-tech products with southern Jiangxi characteristics. With the "100 million" service plan as the starting point, publicize policies such as customs protection of intellectual property rights and technical trade measures through interviews, surveys and special lectures; Continue to publicize the preferential policies of RCEP FTA, vigorously promote and promote the "smart audit+self-printing" smart examination and approval mode of certificate of origin, improve the efficiency of tax reduction and exemption approval, and help enterprises fully enjoy the tariff dividend of FTA; The establishment of an enterprise-related coordinator provides policy advice and professional guidance for enterprises in key parks, strengthens the daily supervision of enterprises, constantly regulates the production and processing processes of enterprises, and ensures product quality.
According to the statistics of Ganzhou Customs, from January to April this year, the total import and export value of high-tech products in Ganzhou was 3.58 billion yuan, accounting for 22% of the city’s total export value in the same period, up 18.5% year-on-year.

China News Service, Haikou, October 4 (Reporter Hong Jianpeng) More than half of the National Day holiday, the number of tourist receptions in Hainan Province is rising day by day, slightly higher than the same period last year. The reporter visited and learned that in addition to traditional tourist attractions (spots), night markets and duty-free shops have boosted tourism consumption in Hainan, and the sales of duty-free goods in the province have increased by 50%.
According to the data provided by Hainan Provincial Department of Tourism, Culture, Radio, Film and Sports, from October 1 to 3, Hainan received 2.298 million tourists. Haikou, Sanya and Boao duty-free shops received more than 80,000 tourists, with sales of 136.6 million yuan (RMB, the same below), up more than 50% year-on-year.
In three days, the daily average number of visitors to Sanya Duty Free Shop exceeded 20,000, and the shopping enthusiasm of tourists continued to rise.
"There are too many people!" This is the first impression of Miss Chen, a tourist from Guangxi, who walked into Sanya Duty Free Shop on the 1st. Duty-free cosmetics are much cheaper than counters, and there are plenty of promotional activities, which make people unable to control their desire to buy.
Xie Zhiyong, executive deputy general manager of Sanya Duty Free Shop Co., Ltd., China National Exemption Group, said that after the opening of Sanya Duty Free Shop, the opening and operation of surrounding hotels and the occupancy rate increased, and the regional development played an obvious role, making it a big taxpayer in Sanya.
Xie Zhiyong said that since Hainan launched the tax-free pilot project for outlying islands in 2011, duty-free shopping has become one of the elements for tourists to travel to Qiong, and Sanya Duty Free Shop has become a must-see spot for tourists. In the future, Sanya Duty Free Shop will fully implement Hainan’s strategic goal of accelerating the construction of Hainan International Tourism Consumption Center, and strengthen and expand duty-free shopping on outlying islands.
With Hainan actively building night economic blocks, night market has gradually become one of the new economic growth points of Hainan’s tourism consumption.
Xiuying district, Haikou City, held the National Day Food Eating Festival for three consecutive days, attracting many citizens and tourists to participate in the interaction of American food tasting and prize-winning questions and answers. "Our night market not only has food, but also Hainan specialty stores, KTV, cinemas and other entertainment places, which can meet the needs of tourism ‘ Eat, live, travel and buy entertainment ’ ‘ among the six elements; Eat, buy and entertain ’ 。” Tan Kaiyue, the person in charge of the taste-seeking Limei vulgar night market, said.
He told reporters that due to the National Day holiday, the night market received more tourists than usual. From September 30 to October 3, the average daily traffic of the night market exceeded 8,000, and the average daily turnover reached 600,000 yuan.
According to the preliminary statistics of Haikou Night Market Development Federation, from September 30th to October 3rd, the turnover of 10 major night markets in Haikou reached 11.1867 million yuan.
Zhan Xiali, secretary-general of Haikou Night Market Development Federation, said that with the Hainan International Tourism Consumption Year launched during the National Day, Haikou Night Market Development Federation will promote the quality of night markets, strengthen the construction of "soft power" such as cultural and performing arts activities, and create "night markets are night scenes".
It is understood that during the National Day holiday, Qiongju performance was staged in Haikou Qilou Old Street, the agricultural fun experience was launched in Sanya Rice National Park, and the "Chili Festival" &hellip was held in Sanya Ancient Love Scenic Area; … Other major traditional scenic spots have also "cooked" a rich cultural tourism "feast" for tourists.
Huawei’s mobile phone was forced to withdraw from the high-end market because the supply of 5G chips was clamped down by the United States. In the past two years, domestic mobile phone manufacturers have hit the high-end market in succession, trying to occupy the market share given up by Huawei. Xiaomi, OPPO, vivo, and glory have piled up hardware, played joint names, and made great efforts in marketing.
A common feature is that mobile phone manufacturers have generally launched sub-brands that take the cost-effective route (such as Xiaomi’s sub-brand Redmi, OPPO’s sub-brand realme, and vivo’s sub-brand iQOO), while parent brand has turned its course to the high-end market.
But this trend was quickly attacked by Apple. The strong momentum of iPhone13 series has given a heavy hammer to domestic mobile phones.
Data show that after the release of the iPhone13 series, Apple ranked first in the smartphone market in China in October 2021, which is the first time that it has returned to the first place in China since December 2015. In November 2021, Apple continued to be the first in the China market, with a market share of 23.6%.
In addition, Apple overtook Xiaomi in the third quarter of 2021 and regained the second place in global sales. Affected by the boost of new product sales, Apple’s total market value once exceeded $3 trillion in the early morning of January 4, 2022, becoming the first company in the world to enter the $3 trillion club.
"Xiaomi’s market share declined in the third quarter (2021), mainly related to the strong performance of iPhone13." Wang Xiang, president of Xiaomi Group, said so on the performance conference call in the third quarter of 2021.
As we all know, Apple’s iPhone has taken three-quarters of the profits of the global mobile phone industry. Only by taking the mid-to-high-end iPhone (the cheapest mobile phone sold by Apple in official website is the iPhone SE, with a price of 3,299), Apple can become the second largest seller in the world, which shows its unshakable position in the high-end market.
On the other hand, domestic manufacturers, after Huawei, have no one to stop Apple’s offensive in the high-end market. An outstanding performance is that after the release of the iPhone13 series in 2021, the price of domestic mobile phones began to "dive" wildly in a second-hand market.
The reason is that with the escalating arms race of mobile phone hardware, it is increasingly difficult for domestic mobile phone manufacturers who lack autonomy in hardware and whose core supply chain is controlled by others to break through in product strength.
If the core supply chain problem is not solved, domestic mobile phone manufacturers will only become more and more passive in the next generation of computing equipment with more extreme performance requirements represented by AR/VR.
01 Apple’s "open plan"
In double 11 in 2021, the price of flagship machine Xiaomi Mix 4 just released by Xiaomi in August plunged sharply into 1000 yuan, and the starting price dropped from 4,999 yuan to 3,999 yuan. The news of price reduction once rushed to the second place in Zhihu’s digital hot list.
In this regard, many users who bought Mix 4 for the first time poured bitterness on social networking sites: "double 11 directly dropped 1,000 yuan. Who will buy the starter in the future? Is the high-end positioning so branded?" "Lei Jun said that Xiaomi only earned 5% of the profits. I believe it. Is it a loss to sell the price down by 1,000 yuan?"
In fact, it has been the norm for many years that the value of Android phones is low and the price "diving" after a period of sale. However, in 2021, the price reduction of flagship machine, a domestic manufacturer, was particularly prominent.
For example, the price of one plus nine Pro double 11 with a starting price of 4,999 yuan dropped to 3,799 yuan, and the price of vivo flagship machine X60 Pro+ double 11 with a starting price of 4,998 yuan dropped to 3,999 yuan, which made many old users call it "broken defense".
Faster price cuts and lower prices naturally mean the loss of profit margins for mobile phone manufacturers, but even so, the price cuts made in flagship machine have not brought about a significant improvement in sales.
According to the report released by BCI, a market research organization, during the two weeks (10.25-11.7) of the Double Eleven intensive promotion, Apple’s sales in the domestic market were far ahead.
The reason is that this is not unrelated to Apple’s initiative to cut prices on the iPhone13 series. This year’s iPhone13 series has been added and reduced in price, and the sales of its products are obvious to all. The 13 Pro series with high version is continuously out of stock.
It is reported that the official price of the 64GB version of the iPhone 12 released in 2020 is 6299 yuan, while the official price of the 128GB version of the iPhone 13 released in 2021 is only 5999 yuan. In addition, various e-commerce activities in double 11 give subsidies ranging from 200 to 500, which makes many netizens shout: Thirteen Fragrances!
Some people in the mobile phone industry believe that the price reduction of the iPhone 13 series is Apple’s "open plan". Apple took the initiative to attack, trying to disrupt the strategic pace of domestic manufacturers attacking high-end, and stop the emergence of "the next Huawei".
From the perspective of the sales volume of domestic mobile phone manufacturers and the "diving" of flagship model prices, Apple’s "open plan" is very effective. In the domestic high-end market, it is difficult for domestic manufacturers to match it.
02 technical short board exposure
Apple is not always a Ma Pingchuan in the high-end market, and it is difficult to meet its rivals. In 2020, Huawei’s mobile phone reached its peak, and it was even with Apple in the high-end market.
According to IDC’s data, in the first half of 2020, Huawei and Apple accounted for nearly 90% of the domestic mobile phone market share in the price range of more than $600, reaching 88.1%. Huawei ranked first ahead of Apple by 0.1%.
But unfortunately, since Huawei’s mobile phone "fell" from the peak because of the chip being suppressed, it is difficult for domestic manufacturers to succeed Huawei and compete with Apple.
This is not unrelated to the technical shortcomings of domestic mobile phone manufacturers.
In the core components such as screen, core processor, CMOS image sensor, especially SoC chip, domestic mobile phone factories such as Xiaomi, OPPO, vivo and Glory all rely on the support of supply chain, while Apple, Samsung and Huawei have all achieved partial autonomy and self-research. It is for this reason that domestic mobile phone manufacturers (except Huawei) have been criticized as "advanced assembly plants".
Especially the SoC of mobile phones, in this field, Huawei used to rely on the Kirin 9000 chip developed by itself to achieve the same performance as Apple A14 chip. However, with the suppression of high-end chips, the self-developed SoC chips have become a swan song, and the high-end flagships of Xiaomi, OPPO, vivo, Glory and other manufacturers all adopt the outsourced Qualcomm Snapdragon SoC chips.
In 2021, when the fever problem of Qualcomm Snapdragon 888 became "Fire Dragon 888", it was difficult for Android phones to compete with Apple using A15 processor in terms of performance and power consumption, and the problem of supply chain autonomy was exposed.
Specifically, the Qualcomm Snapdragon 888 chip in 2021 has some problems, such as high power consumption, high calorific value and fast battery consumption, which greatly reduces the experience of domestic high-end mobile phones in 2021.
The mobile phone manufacturer most negatively affected by "Dragon 888" is Xiaomi. Since the release of Xiaomi 11 series, users have constantly reported that Xiaomi 11 series has serious problems of fever, motherboard burning and WiFi burning. The incident has also been reported by many media.
Even so, the flagship models of domestic mobile phone manufacturers are still dependent on Qualcomm. Qualcomm is almost dominant in the field of high-end SoC of mobile phones.
Just recently, Xiaomi and Lenovo, two domestic mobile phone manufacturers, fought a small "battle" over "who will launch Qualcomm Snapdragon’s next-generation SoC", and Lenovo’s Motorola brand finally won the top spot.
However, it is worth pondering that the performance of Qualcomm’s new generation SoC Snapdragon 8 Gen1 in terms of power consumption and heat generation has not improved much compared with the previous generation 888. A number of commentators pointed out that the mobile phones equipped with Snapdragon 8 Gen1 currently on the market generally adopt the methods of frequency reduction, frame locking and resolution reduction to control the fever of the mobile phones, which makes a certain discount on the actual experience.
Self-developed chip: a difficult and correct way
In fact, Snapdragon 888 chip is not the first time that domestic mobile phone manufacturers have suffered from Qualcomm. In 2015, Qualcomm Xiaolong 810 chip was once called "fire dragon" because of its high power consumption and fever, which dragged down the product strength of a number of Android flagship mobile phones.
In the case that the core supply chain is controlled by people, once an accident happens, it is difficult for mobile phone manufacturers to avoid the negative impact, and there is great uncertainty behind it.
Perhaps affected by this, domestic mobile phone manufacturers have long developed the idea of self-developed mobile phone SoC. Unfortunately, except Huawei, domestic mobile phone manufacturers have not successfully got rid of their dependence on Qualcomm’s flagship chip.
In 2017, the Xiaomi 5C mobile phone released by Xiaomi was equipped with a self-developed 澎湃 S1 processor, but the subsequent 澎湃 S2 failed several times, and the core-making plan finally ran aground.
It is reported that ZEKU (Zheku Technology), a chip subsidiary of OPPO, is also developing SoC chips. Some media pointed out that OPPO plans to OEM its 3 nm SoC chip developed by TSMC. If the research and development is successful, it will be carried on the flagship mobile phone launched in 2023 or 2024.
Judging from the failure experience of Xiaomi 澎湃 S2 and Huawei’s exploration, it is very difficult to develop a mobile phone SoC chip. It takes at least three years to develop a SoC chip, and a lot of money is invested. Lei Jun once described core-building as "a narrow escape" in a speech. This is a great test for the financial resources and courage of mobile phone manufacturers.
However, it is more meaningful to persist in the difficult and correct things. Self-developed SoC can help mobile phone manufacturers to better control the integration of software and hardware, and widen the gap with competitors in experience, especially in the case that Qualcomm’s flagship processor products are not strong enough.
From a longer-term perspective, the next generation of computing platforms, whether AR, VR or Metauniverse, will have significantly higher requirements for software and hardware than mobile phones. This also puts forward higher requirements for the performance of smart device SoC.
Especially the metauniverse, Intel Company pointed out that the metauniverse may be the next major computing platform after the World Wide Web and mobile phones, but the current computing, storage and network infrastructure is simply not enough to realize this vision, and the collective computing power of human beings needs to be improved at least 1000 times.
This means that the next generation of computing platforms will have more extreme requirements for the performance of terminal equipment, and enterprises with self-research capability of SoC chips and high integration of software and hardware will be the winners in the future.
04 written at the end
In terms of software and hardware integration, Apple, which has a closed IOS ecosystem and super A series chips, is second to none. Developing Android system Google also equipped a self-developed Tensor processor on the latest Pixel 6 series mobile phones, trying to make up for the shortcomings on the SoC chip.
However, domestic mobile phone manufacturers still rely more on Android system in software level, and lack the design and manufacturing ability of SoC in hardware level. If this situation is not effectively improved, the road for domestic mobile phone manufacturers will be more and more narrow in the competition of the next generation computing platform.
The core chip is controlled by people, and it is difficult for domestic mobile phones to break the high-end situation of Apple’s "hegemony". The phenomenon that Apple takes three-quarters of the profits of the whole industry will continue to be staged.
Decision of the NPC Standing Committee on Ratifying the Marrakesh Treaty on Facilitating Access to Published Works for the Blind, Visually Impaired or Other Printed Materials Disabled. (Adopted at the 31st session of the 13th the NPC Standing Committee on October 23rd, 2021)
The 31st session of the 13th the NPC Standing Committee decided to ratify the Marrakesh Treaty on Facilitating Access to Published Works for the Blind, Visually Impaired or Other Printed Materials (hereinafter referred to as the Marrakesh Treaty) signed by the representative of People’s Republic of China (PRC) in Marrakech on June 28th, 2013, and stated:
1. The Marrakesh Treaty is applicable to the People’s Republic of China (PRC) Special Administrative Region, and according to the fourth paragraph of Article 4 of the Treaty, the copyright exception stipulated in this Article is limited to works that cannot be obtained in a specific barrier-free format from commercial channels on reasonable terms.
2. The Marrakesh Treaty shall not apply to the People’s Republic of China (PRC) Special Administrative Region until further notice by the People’s Republic of China (PRC) Government.
The thunder storm in Country Garden has aroused widespread concern. In fact, Country Garden, like Evergrande, is a real estate giant that has risen rapidly through crazy leverage in the past few years. However, when the current real estate market tends to be calm, this leveraged model is no longer applicable. Country Garden must face the problems of declining sales and high asset-liability ratio while ensuring that it does not default.
On the other hand, from the sales situation, from 2022 to 2023, the national average price of Country Garden continued to decline, but the sales volume dropped sharply, and its sales were not as good as expected. Moreover, up to 69% of Country Garden projects are located in third-tier cities. With the liberalization of purchase restrictions in first-and second-tier cities, the demand of third-and fourth-tier cities may be diverted, which will further increase the difficulty of Country Garden.
Under the above background, Country Garden announced the restructuring of overseas debts, exchanging time for space. This means that the company can’t cover the interest-bearing liabilities and needs to solve the capital problem through debt restructuring. However, public default is bound to be accompanied by a series of chain reactions, including the sharp drop in sales, the cessation of cooperation among suppliers, the slow progress of the project, and the shrinking of assets. Country Garden can improve sales to solve the financial problem, but the price reduction is no longer possible. Can this road still work?
Judging from the management of housing enterprises, Country Garden executives attempted to imitate Evergrande and isolate and reduce their assets, which caused widespread concern in the market. However, the incident that Xu Jiayin was forced to take measures undoubtedly had a great deterrent effect on Country Garden. Yang Guoqiang doesn’t want to be the second Xu Jiayin. Country Garden actively guarantees the delivery of buildings, which is also a good thing for property buyers.
In a word, Country Garden must adjust its business strategy in time in order to be in an invincible position in the future market.
Country Garden Enterprise is one of the real estate developers in China, established in 1997, with rapid development and huge scale. Judging from the market performance and development strength, Country Garden enjoys a high reputation in the real estate field and is famous for its excellent residential projects.
However, just like any large enterprise, Country Garden also faces some problems. First of all, due to the large-scale development of Country Garden in many places in China, some local governments have raised concerns about over-reliance on the real estate industry and land finance. Secondly, Country Garden, as an enterprise, needs to pay more attention to social responsibility and sustainable development, such as strengthening investment in environmental protection and social welfare undertakings.
Recently, Country Garden’s reorganization of funds has aroused widespread concern. It is reported that Country Garden plans to solve its debt problem by raising funds and internal restructuring. This reorganization may have an impact on Country Garden’s shareholders, employees and suppliers. If the reorganization plan is successfully implemented, it may stabilize the financial situation of Country Garden and bring positive impact on the sustainable development of the enterprise.
However, there are also potential risks and uncertainties in the process of reorganization. For the investors and creditors of Country Garden, they may face some losses. In addition, the reorganization may lead to a chain reaction in the whole real estate industry, which will have an impact on related industrial chains and the job market. Therefore, the government and regulatory agencies should pay close attention to this incident and take appropriate measures to protect the interests of all parties and maintain market stability.
Generally speaking, as an important real estate enterprise, Country Garden plays an important role in China’s social economy. We need to keep an eye on its operation and restructuring plan, and hope that Country Garden can properly solve its problems and make positive contributions to society.
Here is reading the headlines, follow me to learn more. [Rose]
A few days ago, Li Yingbo, vice president of the School of Basic Medicine of Chongqing Medical University, and his party once again came to Denver Children’s Rehabilitation Training Center in Yuzhong District. In the training room, volunteers from the school are assisting several special children to complete passing and jumping.
This is the eighth year that Li Yingbo has been engaged in autism research. In addition to teaching and research, Li Yingbo and his team members also actively participate in various public welfare activities such as rehabilitation training, consulting services, online counseling, community lectures, and on-site interaction. To his delight, the Neuroscience Research Center of Basic Medical College has attracted more and more teachers and students to join his team through the construction of transformational organization.
Chongqing Medical University is a pilot university in Chongqing to build a "Red Rock Pioneer" transformational organization in the new era. The Party Committee of the school explores the breakthrough of the traditional functional organizational structure of compartmentalization and vertical management, and promotes the model innovation of "one party is subordinate to one party and multiple management" in party member by creating a mixed organizational form that integrates various types.
In April this year, the basic medical college of our school co-ordinated a number of teaching and research departments engaged in neuroscience research, such as anatomy, physiology and pathogens, fully mobilized teaching and research staff and students, and established an innovative party organization of the neuroscience research center of the basic medical college. Innovative Party organizations integrate experts and scholars in related fields, and concentrate their efforts on scientific research around severe brain diseases such as cerebrovascular disease, Alzheimer’s disease and depression. Such cross-disciplinary collaborative research has achieved tangible results.
Zhao Mingming, a professor in the Department of Histology and Embryology of Basic Medical College, said that the innovative party organization integrated the disciplinary perspective, promoted interdisciplinary research, and promoted cross-cooperation among many research groups. "While building a high-quality research team, it also played the vanguard and exemplary role of party member".
"I learned about the autism research team for the first time at the organization life meeting. Today is the second time to observe it on the spot, which has accumulated valuable clinical experience for basic scientific research." Zhao Mingming believes that the innovative party organization, as a flexible and innovative form of party organization, can not only tackle key problems through problem-oriented organization, but also connect cutting-edge medical research, basic talent training and social welfare activities, "so that the effectiveness of party building can be felt in all aspects".
Breaking the boundaries between colleges, departments and grades, and improving the "all-coverage organization system" through innovative party organizations have also brought real changes to the student community.
Liu Zhaohong, director of the Student Affairs Office of Jinyun Campus, the First Clinical College of Chongqing Medical University, introduced that after the establishment of the innovative party organization, party building education activities such as "face-to-face discussion and exchange of young students" and community humanities lecture halls were held in the student community every week, and students could also invite famous academic and industrial teachers to share and exchange with the student community according to the project resources such as "College leaders talk about party classes", "Ideological and political teachers enter the community" and "Professor Reception Day".
"Following the concept of’ where there is party member, there is a Party organization’, innovative Party organizations have been established in the teaching and research fields and student communities of the whole school. The school supports and guides the innovative party organizations in the student community to carefully plan’ one community, one brand’, fully integrate’ five educations simultaneously’ into organizational activities and student community management, and lead the whole process of’ three-all education’ with the construction of transformational organizations. " Qin Zhengjie, secretary of the Party Committee of Chongqing Medical University, said.
Cctv newsThe China Consumers Association today issued a warning on children’s toy consumption, reminding parents to be careful of five types of "dangerous toys" injuries.
China Consumers Association invited experts from the Secretariat of the National Toy Standardization Committee to analyze and sort out the injuries caused by common "dangerous toys", and found that the most common injuries caused by dangerous toys are mechanical physical injuries, chemical injuries and injuries caused by misuse of non-toy products. These five types of dangerous toys include:
1. Small toy parts are easy to fall off, and there is danger of swallowing and suffocation.
Small ornaments and accessories, such as buttons and marbles, which are easy to fall off in some unqualified toys, are easy to be swallowed by young children or stuffed into their nostrils, resulting in the risk of swallowing foreign bodies and suffocation. If it is a small part with magnetic material, it will bring further harm once it is eaten by mistake.
According to experts, ifChildren swallowing two or more powerful magnets may cause gastrointestinal perforation or intestinal obstruction, which may be life-threatening in severe cases.
2. Toys have dangerous sharp points and sharp edges, and there is a danger of puncture.
Some inferior toys have sharp edges, sharp points, rough burrs and other protrusions on the surface, or the toy structure is fragile, forming sharp small parts, which are very easy to stab children. For example, a kind of fingerPointed gyroOur products have sharp edges and sharp tips that can be touched, which may cause body scratches, pricks and other injuries.
3. Toys use inferior materials, and there is a danger of chemical pollution.
There are dangerous toys with chemical pollution, such as plush toys filled with unsterilized waste materials, colorful colored mud, dolls made of inferior plastics, etc. Their sanitary conditions and the migration of chemical harmful substances all pose potential dangers to children’s health. Many small shops around schools sell them."crystal mud"Some of them contain more than a certain amount of borax, which may cause chronic poisoning and pose a safety hazard if they enter the human body through children’s oral and skin contact.
4. Non-toy products are used as toys by mistake, resulting in injuries.
Children will use some items in their daily lives as toys, and this kind of improper use hides great danger. Such as children playing by mistake."laser pen"Causing vision loss, and it is common in the family.Water SpiritAlso known asSea baby, bubble beads, water-absorbing shells.. Because it has the functions of absorbing water and retaining water, it is widely used in potted plants and indoor decoration, which may be mistaken for food by children, leading to children swallowing or inhaling it by mistake.
5. Don’t buy and use toys according to their age, which leads to danger.
In China, the labeling and description of toys for children under the age of 14 are mandatory. Children of different ages have great differences in physical development and cognitive ability. Violation of the applicable age limit may pose a threat to children’s safety.
In view of the problems existing in toy consumption, China Consumers Association warned:Do not buy toys without factory name, address and 3C certification mark.Choose suitable products according to your age, and don’t buy "three noes" products in small commodity markets, bazaars and online stores.
Be careful to buy toys that may have small parts that fall off easily. Avoid buying products with scattered parts, small magnetic parts, sharp metal edges and rough burrs. China Consumers Association said that China has implemented a toy recall system, suggesting that consumers find toy safety risks or injury accidents and report them to the Defective Product Management Center of the State Administration of Markets to prevent the harm from expanding.

Chinanews. com client Beijing, April 10 th:If you can’t flirt, you will be fooled: can you fight harassing calls?
Reporter Wu Tao
"Do you need to buy a house?" "What about unsecured loans?" "How about stock investment recently?"
This year’s CCTV 3.15 party exposed the madness of harassing calls. Has the situation of harassing calls improved now? The reporter’s investigation found that there are still people who are "committing crimes" against the wind, and some users have reported that the number of harassing calls has increased significantly recently.
"My phone number is rotten on the street."
Gao Ning (pseudonym) left personal information such as telephone number in a real estate in Qinhuangdao in 2016. From then on, he will receive a phone call to ask if he wants to buy a house, which has continued until now.
"The key is not only this property, but also several properties have been called to me. I suspect that my phone number has been ruined in the Qinhuangdao real estate agency circle." Gao Ning said.
There are many people like Gao Ning. Recently, some users told reporters that although the 3.15 party exposed the rampant situation of harassing calls, the frequency of receiving harassing calls has not dropped significantly recently. He counted the harassing calls he received in the past month, about six, and received one every five days on average.
The point is, it takes no effort or time for people to harass you. "I often get harassing calls, and I am so angry that I once wanted to flirt with the harassing phone and talk nonsense with it for 5 minutes. Recently, I learned that harassing calls can be used for robot chat, and I think of this matter as angry and funny. " The above users said.
Because software and labor are different, the efficiency is very high, even if it is not aimed at fixed user groups, the cost is not high. A company official said that they made more than 4 billion harassing calls a year.
A software marketer said that taking making 2000 calls as an example, the efficiency of their software is 6-8 times that of normal manual work.
According to the first telecom service quality notice of the Ministry of Industry and Information Technology in 2019, in the fourth quarter of 2018, the 12321 report acceptance center accepted 230,694 complaints and reports from users about harassing calls, down 5.1% from the previous month. Although the number of complaints and reports declined, it was still at a historical high.
Want to call back and scold after being harassed? "Call failed"
The reporter noticed that the current harassing phone technology has been upgraded rapidly. For example, everyone has the impression that there are more harassing calls at 400 and 800, and now many of them start with 95 and 96.
The reporter experimented that users can only passively accept harassing calls at the beginning of 95, even if they call back, and the call back shows "Call Failed".
Some harassing calls are more confusing and look just like ordinary numbers. It is understood that this may be because the harassing phone used the technology of virtual calling and changed the calling number in order to gain the trust of users.
In March, the Ministry of Industry and Information Technology issued a message to strictly investigate the violations of virtual calling numbers using transparent transmission technology, and intercept all calls that failed authentication.
Who is "boosting" harassing calls?
Like "no business, no harm", the rampancy of harassing calls cannot be separated from the "assistance" of some enterprises.
A few days ago, Beijing Communications Administration focused on Baidu, Qihoo 360, sogou and other search service providers in response to the harassment of telephone software sales promotion information found on the Internet, and asked the three companies to rectify. All three companies said that they would thoroughly investigate the problems and immediately rectify them.
Afterwards, the reporter from Zhongxin. com consulted the public relations staff of a search engine company mentioned above, and the other party looked "stunned". "Huh? Have we been interviewed? " It is conceivable that enterprises do not attach importance to this matter.
Recently, reporters searched for keywords such as "telephone software" and "telemarketing", and there are still related softwares doing search promotion. There are many softwares that support robot marketing, autonomous speech configuration and human-computer interaction.
The Ministry of Industry and Information Technology has clearly stipulated that all Internet companies should comprehensively clean up the information of harassing software and equipment such as "calling you to death" on the Internet, and cut off the promotion, sales and use channels of related software and hardware.
Some marketing robots on e-commerce only sell 400 yuan for one year.
More seriously, it’s not just search engines. The influence of harassing telephone software has penetrated into many fields such as e-commerce and social interaction.
Reporters lurked in QQ groups selling several telephone software and found that people kept sending out advertisements to make outbound calls. Moreover, according to the description, the software was very powerful, and intelligent robots, screen-blocking short messages, and all invalid numbers such as shutdown and empty numbers could be automatically filtered out.
On the idle fish of the second-hand trading platform, there are also marketing robots for sale, which can be called out in batches, and the robot simulates customer service. And the price is very cheap, 400 yuan every year.
This year’s 3.15 party also revealed that some enterprises are selling probe boxes, which can collect personal information such as users’ phone numbers when placed in crowded places such as Shangchao. Among these enterprises, there are many listed companies with strong technical and financial strength.
Why is it difficult to eliminate?
Some insiders told the reporter of Zhongxin. com that the reasons why harassing calls are difficult to eliminate are very complicated, including difficulties in implementation and serious information leakage.
"Take the source of the harassed phone number as an example. It turns out that Internet companies are often exposed to information leakage, and Internet companies say ‘ Hit the library, reported ’ It’s over, but there is endless thunder: these numbers will be repeatedly bought and sold, and even classified and sold to different marketing companies. "
Even if there is no number resource, harassing calls can still be made. The reporter also noticed that some telemarketing software claimed that "without customer resources, the system will be automatically generated."
Operators may also be responsible for harassing calls. In November 2018, the notice issued by the General Office of the Ministry of Industry and Information Technology on the "Work Plan for Promoting the Special Action of Comprehensive Remediation of Harassment Calls" showed that all basic telecommunications enterprises and mobile resale enterprises should provide domestic mobile phone users with the reminding of the number of suspected harassing calls and the ability to prevent and control risks. And marked to be completed before the end of March 2019.
Thirteen departments, including the Ministry of Industry and Information Technology, have also asked all basic telecommunications enterprises to strictly examine the user qualifications of voice lines and code number resources such as 95, 96 and 400 in accordance with the principle of "whoever accesses them is responsible" and standardize the use of resources.
However, some users have reported that the harassing calls received at present are rarely marked. Although they see strange numbers, they will still answer them for fear of missing important calls. "Some numbers starting with 95 will also change the tail number to call you. The actual promotion is one thing, and it is impossible to prevent it."
Some insiders of the operator told the reporter of Zhongxin.com, "The key is that it is impossible to judge what is a harassing phone call. For example, a phone call to sell a house is harassing for those who have no need to buy a house, but it is just needed for those who urgently need to buy a house."
From this point of view, there is still a long way to go to rectify harassing calls. (End)
With a pink nose, small eyes, wide and flexible ears and a broom-like tail, the pig-tailed mouse, known as the "blind mouse", has an echolocation ability.
Recently, researchers from Kunming Institute of Zoology, Chinese Academy of Sciences came to this conclusion.
The research groups of Shi Peng, Jiang Xuelong and Liu Zhen, the State Key Laboratory of Genetic Resources and Evolution of the Institute, jointly tackled the problem, and confirmed that the species of the genus Rodent has the ability of echolocation by integrating several independent evidences of ethology, anatomy, genomics and gene function experiments.
"In addition to the well-known bats, toothed whales, etc., pigtail rats also have this ability, which is amazing in itself!" On July 5th, one of the researchers, Dr. Liu Qi from Shi Peng’s research group, was interviewed by The Paper (www.thepaper.cn) and introduced that the research on echolocation ability of pigtail rats lasted for about 4 years. This study is expected to make the pig-tailed rat become a new experimental animal to study the neural circuits of sound, hearing and echolocation. He also hopes that the research results can be applied to artificial intelligence in the future, such as improving auto-driving and blind-assisted navigation.
"Are there other mammals that have this ability but have not been discovered?" Liu Qi believes that there is still a lot of room for the research and application of echolocation, and the research on pig-tailed mice is only the beginning.
The experiment lasted for nearly four years, and the researchers stayed up late with the pig-tailed rats.
The nose is pink, the eyes are small, the ears are wide and very flexible, just like bats, they will swing back and forth and collect sounds in different directions. Its tail is very long, shaped like a broom, and there is a pinch of white hair at the end of it.
This is Liu Qi’s research object-pigtail rat, which is also called "blind rat" because of its small eyes. It belongs to the genus pigtail rat of Rodent Echinopodidae.
Liu Qi studied the echolocation ability of pig-tailed rats. Echo location refers to a directional behavior of animals in navigation, foraging and other activities by comparing the information difference between sending sound waves and receiving echoes.
As early as 2017, Liu Qi had already started this research.
At that time, after he did some basic work, the experiment had preliminary research results. He organized the experimental content into an English manuscript and sent it to secience magazine in the form of a short article. Journals have given great affirmation to this research achievement and shown great interest, which has given them great confidence.
"In the later process, we supplemented many experiments according to the requirements of the magazine and constantly enriched and improved the paper." Liu Qi said that on the one hand, it is necessary to obtain accurate experimental evidence from many aspects, on the other hand, the workload of each experiment is very large, including the subsequent papers being revised many times, so the whole project involves a long time, and it is a joint effort of multiple research teams.
Liu Qi introduced that the correspondence authors Shi Peng and Liu Zhen’s research group have been engaged in the research on the convergent evolution and molecular genetic mechanism of echo localization for a long time, and have published many heavyweight research results. Another cooperative team, researcher Jiang Xuelong, who is also the correspondent of the paper, is engaged in the research on the behavioral ecology, phylogeny and classification of pig-tailed rats. This research is the result of joint research by three research groups.
Although there are three top teams in the joint experiment, there are many difficulties in the experiment.
Liu Qi introduced that the first difficulty comes from the research object-the pig-tailed rat. Before the study, they didn’t know much about the living habits of this kind of wild animal, such as what it eats, where it lives, whether it lives in groups, what its nest looks like and its activity time.
Secondly, the wild population of pigtail rat is not large, so it is a big problem to catch it and catch a certain number of live pigtail rats when doing experiments with it.
At the same time, the researchers have no experience in raising pigs. After catching a certain number of pigs, they don’t know how to raise them. They are worried that the artificially created conditions can’t make pigs behave naturally.
However, with the advancement of the experiment, solutions have been found to these difficulties.
What makes Liu Qi feel very interesting is that in the experiment, they found that animals such as pigtail rats are nocturnal. They sleep during the day and are more active at night. Therefore, in the process of behavioral experiments, researchers arrange experiments at night, and sometimes they have to work all night to complete an experiment.
The echolocation function of small-eyed "blind mouse"
Liu Qi said that in the experiment, they recorded the short-term, frequency-modulated and high-frequency sound waves (peak frequency ~98 kHz) regularly emitted by the pig-tailed rats during movement. In dark environment, pigtail rats will emit higher ultrasonic velocity in complex space environment and when avoiding obstacles. All these results show that the ultrasonic waves emitted by pigtail rats play a directional role in sports behavior, that is, echolocation.
Subsequently, the researchers used classic experimental devices and strict experimental design to verify whether the pigtail mouse has the ability of echolocation. Through the behavioral task experiment, it is found that the pigtail rats will spend more time and send out higher ultrasonic speed to explore the target. They can accurately detect the escape platform and successfully obtain food rewards in complete darkness. When its ears are blocked, the pig-tailed rat can’t receive the echo and can’t detect the target and complete the task; After removing the earplugs, the pig-tailed rat recovered its ability to explore and locate the target. Under the condition of eliminating vision, touch and controlling sense of smell, behavioral experiments confirmed that the pigtail mouse achieved its goal by emitting ultrasonic waves and receiving echoes by hearing.
In addition, the researchers used technical means to present the anatomical structure of the pig-tailed rat, and found that the spatial position of its hyoid bone and tympanic bone contacted and fused, which was consistent with the structure of the echolocation bat that sounded through the throat. This shows that the pig-tailed rat and the echolocation bat with laryngeal vocalization have the same anatomical structure basis in vocalization and auditory structure.
Liu Qi and other researchers also sequenced and assembled the high-quality whole genome of the Chinese pigtail mouse. Through evolutionary genomics analysis, it was found that the echolocation of the pigtail mouse originated independently. In the whole genome, the pig-tailed rat and the known echolocation species (bats and toothed whales) are significantly enriched in auditory genes.
By integrating several independent evidences of ethology, anatomy, genomics and gene function experiments, it is confirmed that the species of the genus Rodentia has the ability of echolocation.
It is expected to be used in artificial intelligence, blind-assisted navigation and other fields.
The echolocation ability of pigtailed rats seems to be inferior to that of ordinary people. However, Liu Qi said that this research may be applied to artificial intelligence in the future, such as improving auto-driving and blind-assisted navigation.
Liu Qi said that from the perspective of science itself, echolocation, as a special behavior of animals, is very rare in the animal kingdom. At present, the echolocation species known by human beings may be limited to a few kinds, such as bats and toothed whales, which are familiar to everyone, and some unfamiliar ones, such as some birds, shrews and hedgehogs.
"In addition to the animals listed above, we have confirmed that there is another kind of mouse, which also has echolocation skills. It is amazing in itself to find food or locate targets by hearing and ultrasound!" Liu Qi said that in addition to five groups of independent origin, such as bats, toothed whales and giant whales, the research team found a sixth group with this ability.
In addition, because the pig-tailed rat is a rodent, its genetic relationship and size are close to those of model animal mice, and its breeding is easy to operate, it is expected to become a new experimental animal to study the neural circuits of sound, hearing and echolocation.
Liu Qi said that human beings have developed many bionic products based on the long-term research on echolocation species such as bats. For example, bats will send out ultrasonic waves to detect targets, track moving prey, or avoid obstacles in time. The invented guide rod is convenient for the blind to move.
He admits that there is still a lot of room for the research and application of echolocation, and the research on bats, pigtails and other animals and their echolocation will have more influence on human life in the future.
After discovering that pigtail rats have echolocation ability, Liu Qi and his research team have been thinking about whether there are other nearly 6,000 kinds of mammals in nature that have this ability but have not been discovered. They hope that through the efforts of the team, they can find more such magical animals.
"This requires the unremitting efforts of many researchers, and it may even be a very long exploration process." Liu Qi said that the discovery of pig-tailed rat and its echolocation is only the beginning. They hope to stick to this research and expect that it can be used in artificial intelligence in the future, such as improving auto-driving and blind-assisted navigation.
