　　Allergy survey ②

　　Generally speaking, the results of allergen detection combined with medical history are relatively reliable. Allergic people don’t need to do allergen testing regularly, just wait until they have allergic symptoms but are not sure about allergens. In addition, they should choose professional and qualified institutions for testing.

　　Is allergen testing reliable?

　　This is one of the most frequently asked questions by Hu Liang, a pediatrician in Changchun Children’s Hospital. Many people suffer from allergies. In order to find allergens, they went to the hospital for allergen testing, and found that they were "lonely". The test results did not seem to be very helpful to control allergies.

　　So, what are the main methods of allergen detection? How effective are these methods? Why do some people feel that they have "tested in vain"? Around these problems, the reporter of Science and Technology Daily interviewed relevant experts.

　　Identifying allergens is the key to controlling allergies.

　　Allergic diseases are also called allergic diseases, commonly known as allergies. According to the data, it is estimated that by 2050, about 4 billion people in the world will suffer from allergic asthma, allergic rhinitis and atopic dermatitis, and allergy has become the sixth largest chronic disease in the world.

　　Allergy is closely related to allergens.

　　Jiang Weihong, chief physician of the Department of Otolaryngology, Head and Neck Surgery, Xiangya Hospital, Central South University, said that allergens enter the human body through oral administration, inhalation, contact or injection, and bites, and allergic reactions occur in the human body. Therefore, if you want to control allergies, the key is to diagnose and determine allergens. Only by clarifying the cause of allergy can we correctly choose the treatment plan.

　　However, there are many kinds of allergens in life, the most common are food allergens and inhalation allergens, and some are contact allergies.

　　So, how can we "find out" the allergens that really cause allergies? This requires allergen testing.

　　Liu Yongsheng, director of dermatology department of Aviation General Hospital, said that patients with allergies will produce specific IgE in their bodies after being exposed to allergens, and then the specific IgE will enter the circulatory system and be transported to all parts of the body, where it will combine with mast cells and basophils. Mast cells and basophils combined with specific IgE will meet and combine with allergens again, and then trigger mast cells and basophils to release inflammatory factors, such as histamine, which can directly lead to allergic inflammation and cause symptoms of type I allergic reaction in human body.

　　"So, what is usually called allergen testing is specific IgE." Liu Yongsheng said.

　　Different detection methods have their own advantages and disadvantages.

　　Liu Yongsheng introduced that the methods of allergen examination can be roughly divided into intradermal test or prick test, serum test, patch test and provocation test.

　　The principle of intradermal test or prick test is to let a certain amount of allergens enter the skin through a specific way, and then observe whether the allergens will cause allergic reactions, and judge the degree of allergies according to the degree of local skin allergic reactions, which is commonly known as "prick test". Liu Yongsheng said that this method has the advantages of simplicity, convenience and intuitive results, and patients will not wait too long for examination results.

　　If intradermal test or prick test is an indirect method to determine specific IgE in vivo, then blood test is a means to directly determine specific IgE in serum.

　　Shi Haiyun, chief physician of the Department of Allergy, Beijing Shijitan Hospital affiliated to Capital Medical University, said that if patients are unable or unwilling to adopt intradermal test or prick test for various reasons, they can choose to directly determine the specific IgE in serum. If specific IgE can be detected and reaches a certain value, it can be preliminarily judged to be allergic. By measuring the content of specific IgE in the body, such as serum, the degree of allergy can be preliminarily judged. However, serum examination requires special equipment and high cost, and the patient needs to wait for several days or more for the examination results. In addition, at present, the types of allergens that can be detected by serum testing are limited.

　　If contact allergens are detected, patch test can be used, and when allergens are unknown, patch test can also be done. The operation method of patch test is to stick the reagent on the skin, and after observing for a period of time, judge whether the subject is allergic to the substance according to the skin’s reaction to the contact substance.

　　Liu Yongsheng added that another way to check allergens is provocation test, such as oral food provocation test, nasal mucosa provocation test, conjunctival provocation test and bronchial provocation test. The principle of these tests is to simulate a real allergic reaction, which has certain risks and is not often used in clinic.

　　Shi Haiyun said that allergen detection methods have their own advantages and disadvantages, and which allergen detection method to adopt should follow the doctor’s advice.

　　Liu Yongsheng said that after the allergen test, the doctor should make a comprehensive judgment according to the patient’s medical history to determine whether he is allergic. "In addition, patients should pay attention to observing and recording substances that may cause allergies in order to find and avoid corresponding allergens."

　　Allergen detection may have some blind spots.

　　Although the methods and techniques of allergen detection are relatively complete now, there are also cases in which allergens cannot be detected or allergens are misjudged in clinic. In this regard, Liu Yongsheng explained that due to many factors, to some extent, there are some blind spots in allergen testing.

　　Some blind spots are related to allergen detection methods. Taking the prick test as an example, patients with skin scratches may have false positive results. That is to say, some people were not allergic originally, and the allergen itself did not cause allergic reaction in patients, but acupuncture operation caused skin redness, swelling, itching and other reactions, which made inspectors mistakenly think that patients had allergic reaction.

　　Some blind spots are caused by external factors. For example, heating is one of the commonly used ways in food processing, and when food allergens are detected by immunological methods, heating will lead to changes in the structure of protein (allergen), so that antibodies cannot correctly identify the detected allergens, resulting in false negative results. For another example, ELISA is one of the commonly used methods to detect allergen wheat, but it is easy to cause false negative or false positive results because the samples are easily cross-contaminated.

　　Liu Yongsheng introduced that some blind spots of allergen detection are related to the complexity of allergen itself. There are about five or six hundred kinds of external allergens, and traditional methods can only screen 10 to 30 items, which is not comprehensive. Moreover, allergen detection is a meticulous work. For example, milk is one of the eight major allergic foods, and there are more than 30 kinds of allergic protein in milk. To determine which protein is allergic, more sophisticated detection means are needed. "Some people are allergic to cats, but whether they are allergic to cat hair, cat dander, cat saliva or cat urine, it is not clear from an allergen test." Liu Yongsheng said.

　　It is worth noting that some allergic patients take anti-allergic drugs before testing allergens, which will also cause false negative test results. Experts suggest that if the intradermal test is chosen to detect allergens, patients should stop taking antiallergic drugs for about 7 days, and some drugs need to stop taking them for a longer time.

　　"In addition, the relevant technologies and equipment for allergen testing and the level of doctors who test allergens for patients may also affect the results of allergen testing." Liu Yongsheng added.

　　"In order to accurately lock allergens, not only excellent technical means are needed, but also doctors need to patiently ask about medical history. Combining allergen detection methods and medical history to judge allergens, generally speaking, the results are relatively reliable. " Liu Yongsheng suggested that allergic people don’t need to do allergen testing regularly, but only when they have allergic symptoms but are not sure about allergens. In addition, they should choose professional and qualified institutions for testing.

The most cost-effective reward exchange method of the original Shenchen singing pot is to exchange resin first, followed by the essence of holy relics, then the experience book and Mora.

The most cost-effective reward exchange strategy for the original Shenchen singing pot

First, the most cost-effective reward exchange method of the original Shenchen singing pot is to give priority to resin exchange, followed by the essence of sacred relics, then the experience book and Mora.

Second, the original magic dust singing pot reward cost-effective calculation method

1. Reward redemption is refreshed once a week, and according to the redemption value obtained online in advance, a total of 12,000 treasure money is needed in one week.

5040 is far less than 12000. It is not enough to redeem all the weekly rewards, so we need to plan the redemption of the required items.

2. Calculate the ratio of each item to the standard value.

(Because each item needs different treasure money, the treasure money will be unified in the end, and 30 treasure money will be taken as 1)

(1) resin, 1200 treasure money, in exchange for 60 pieces, which is equivalent to the standard value. 3. Take 30 treasure money as 1.1200 treasure money and 40.

Standard value 3÷40=0.075 (cost performance)

(2) experience book, 120 treasure money (4 30), 20000 experience.

If the minimum experience cost is 110,000, the cost performance ratio is 2÷11÷4=0.0454545… …

If the maximum value is 135,000, the cost performance ratio is 2÷13.5÷4=0.0373737… …

③ Mora, 120 treasure money, 10,000 mora and 60,000 flowers are fixed, so the price-performance ratio of Mora is 1÷6÷4=0.04166666… …

(4) Essence/ointment, which are equivalent. The former has 360 treasures and 10,000 relics experience, while the latter has 90 treasures and 2,500 relics experience.

The cost performance ratio is 10000 ÷ 13860 ÷ 12+2525 ÷ 60000 ÷ 12 & asymp; 0.063632004569504569

Conclusion: According to the above calculation, the cost performance (in exchange for priority):

Resin > essential oil/ointment > experience ≈ Mora

Conclusion:

As you can see, the income of resin is greater than the other three (Mora, experience, relic experience), and it is the first priority to exchange, and it will not lose money.

Then, if you need dog food and don’t want liver, of course, the relic experience (essence/ointment) is better than the other two.

Changan Suzuki owns a small suv called Vitera, which went on the market in November 2015 and sold very well, but it was mass-produced in 2015.

Now, Suzuki’s new small SUV Vitera will be on the market. The fuel consumption of this model is 5.4L, only 100,000 yuan. All the riders said Suzuki was finally crazy.

Design:

At the Geneva Motor Show earlier this year, Suzuki Vitera, a brand-new small suv, was officially unveiled. Compared with the cash, the new car has changed its appearance and adopted a new peripheral design. In terms of appearance, the overall shape of the vehicle has not changed, and the shapes of daytime running lights and fog lights on both sides are consistent with the cash.

In addition, the new car is also equipped with a radar probe module, which is expected to add functions such as automatic emergency braking or ACC adaptive cruise, and the configuration will be improved. At the same time, the new car also provides a variety of kits for users to choose from, including LED headlights and LED rear combination lights, silver luggage rack, panoramic sunroof, front/rear bumper decoration, side sill pedals and body wiper, etc., which can better meet the diverse and personalized needs of consumers.

Internal parts:

However, except for some minor rectification on the center console of the car, the interior of the car is similar to that of the previous generation. Should it be simpler than before? At the same time, some physical buttons of the car are installed on both sides of the steering wheel. However, the seat seems to be made of genuine leather /Alcantara, and a new sewing method is set on the surface of the seat, which makes the original rigid seat of Suzuki’s new small suv look more sporty.

Power system and chassis:

As for the core power system and chassis, the Vitera of Suzuki’s new small SUV will not change much, and it will still be equipped with a 1.4T+6MT/6AT-based power system, which will also match the previous four-wheel drive system. I don’t understand why Changan Suzuki is unwilling to extend the wheelbase of Vitera, which seriously affects the competitiveness of this car. On the contrary, Changan Suzuki has always insisted on four-wheel drive. Is the four-wheel drive system really that important for an urban SUV?

This time, the original factory of Suzuki’s new small suv is mainly aimed at the improvement of technical equipment, especially the active safety system that the European market cares about. Suzuki will use the same monocular camera lens+laser radar as Swift to replace the original monocular camera lens+millimeter wave radar wave, and the front windshield will have monocular camera, laser receiver and laser sensor.

The above is the introduction of Vitera, Suzuki’s new small SUV. I believe many friends are interested in this "fuel-saving king", the price is only 100,000 yuan, and the cost performance is also very high.

　　[PConline information]In summer, the most comfortable thing is to play with your mobile phone while eating watermelon in an air-conditioned room. In the big summer, such a hot summer, my life is definitely given by air conditioning. But as we all know, if you want to enjoy it, you have to pay. The biggest power consumption in summer is also air conditioning. Usually, the electricity bill in July and August is just a few hundred dollars. Whenever I receive the electricity bill, I always feel that the cost of continuing my life in summer is really high. Does the power consumption of air conditioners have to be so large? As the saying goes, many a mickle makes a mickle. Is there any clever way to save electricity?

　　Working principle of air conditioner

　　Refrigeration is the most commonly used air conditioner. After the air conditioner is powered on, the low-pressure vapor in the refrigerant in the refrigeration system in the air conditioner will be sucked by the compressor and compressed into high-pressure vapor, which will be discharged to the condenser. The outdoor air sucked by the axial flow fan will flow through the condenser, so that the high-pressure refrigerant vapor will be condensed into high-pressure liquid, which will be sprayed into the evaporator after passing through the filter and throttling mechanism, and will evaporate at the corresponding low pressure to absorb the surrounding heat, so that the indoor air will continuously circulate and flow, thus achieving the purpose of reducing the temperature.　　　　

　　Frequent switching consumes electricity instead.

　　Some people may think that it costs electricity to keep the air conditioner on, so they turn it off when it is not hot, thinking that the purpose of saving electricity can be achieved by constantly turning it on and off, but in fact it may cost more electricity. Because the power required by the compressor inside the air conditioner is very large when it is started, it is generally about 4 or 5 times higher than the normal working current. As a result, it will naturally cost more electricity to switch the air conditioner on and off frequently. In addition, it is easy to burn out the compressor if the air conditioner is turned on and off frequently.

　　Small coup of saving electricity in life

　　1. Unplug the air conditioner when it is not in use, because as long as it is plugged in, the air conditioner will consume electricity. Although the power consumption is not much, its power consumption cannot be ignored over time.

　　2. Turn on the air conditioner in summer, and don’t pursue too low a temperature, which not only consumes more electricity, but also easily causes symptoms such as colds. According to scientific data, the most suitable temperature for human body in air-conditioned room is 26℃~28℃, which can not only make people feel cool, but also make them more comfortable and save electricity.

　　3. If you go out for a short time, usually within an hour, there is no need to turn off the air conditioner, because as mentioned above, it is more electricity-consuming to switch the air conditioner at high frequency.

　　4. When cooling, the air outlet of the air conditioner is upward, because the cold air flow is heavier than air and will sink, so the cooling efficiency will be more obvious when the air outlet is upward.

　　5. When sleeping at night, choose the sleep mode that comes with the air conditioner. Generally, the air conditioner sleep mode will make the machine run in a low power state, which will not only make the noise less, but also make the sleep more comfortable with proper air volume.

　　6. In an air-conditioned room, the air temperature is low. At this time, with an electric fan, the cooling effect will be better. Because the power of the fan is far less than that of the air conditioner, and the fan can stir the air, making people feel cool. The air conditioner makes the indoor air cool, and the coolness is more obvious after being matched with an electric fan, so that the temperature of the air conditioner can be raised, which is more comfortable and saves electricity.

　　7. When installing the outdoor air conditioner, we should also avoid it being exposed to direct sunlight, because the outdoor air conditioner will radiate heat into the ambient air in summer, and the direct sunlight will increase the difficulty of heat loss, and the cooling effect of the air conditioner will become worse. If conditions are limited, we can install a sunshade. Try to choose thicker curtains indoors, and then close them, which can also reduce the loss of chill.

　　8. The last point is to clean the air conditioner regularly. Because of the long-term use of the air conditioner, the internal filter screen of the air conditioner will be covered with pollutants such as dust, and in serious cases, bacteria, mites and Legionella will also breed. It will not only block the vent, which will reduce the refrigeration efficiency, but also affect our breathing health. It is best to clean it once every half a month or once a month when using it at ordinary times.

　　Learn these tips, I believe we can save a lot of electricity bills, and use air conditioners correctly, which is environmentally friendly and saves electricity. Why not? Of course, it is really pleasant to stay in an air-conditioned room in summer, and everyone should pay attention to controlling the time. When the temperature is not high every morning and evening, opening the window for a few hours will help everyone’s health.

??? Foreign media said that year after year, generation after generation, Apple’s latest product launch always attracts a large number of loyal fans. On September 16 this year, the "fruit powder" all over the world greeted the listing of iPhone 7 with expectation, patience and long queues.

　　Effie reported on September 16th that iPhone 7 has a more professional camera, longer battery life and waterproof function, and can also be paired with wireless headphones. Attracted by these innovations, Apple retail stores in new york, Sydney, Tokyo and Madrid welcomed the first batch of "fruit powder" with a large number of people. In front of the Apple retail store in Los Angeles, people lined up early, waiting to open the door at 8 am to buy the iPhone 7.

　　Although there are many people, the team is orderly. People also prepared books, coffee, food, folding chairs and mobile phones to pass the time. At the same time, some people try to bargain with the people in front, just to buy their good seats. Employees of Apple’s retail stores told the long queue of "fruit powder" that the iPhone 7 Plus and iPhone 7 of "Piano Black" were not sold in any physical store that day due to the high online booking volume.

　　IPhone 7 will land in 25 countries and regions around the world today, and a new smart watch, the second generation Apple Watch, will also be unveiled. In Sydney, Australia, about 200 "fruit fans" lined up in front of Apple retail stores two days in advance. There are also hundreds of "fruit powders" gathered in front of the apple store in Tokyo, Japan. A Japanese "fruit powder" who is queuing told reporters that he started queuing two days ago. Similar pomps also took place in Beijing, China and Madrid.

　　However, there are also some fake "fruit powders" in the long queue. They seek profits by reselling mobile phones or replacing queues. The popularity of Apple mobile phones by "fruit powder" has even spawned some small companies instead of queuing in new york.

　　The price of iPhone 7 ranges from $649 to $849, while the price of iPhone 7 Plus ranges from $769 to $969.

　　Effie reported on September 16th that the latest Apple mobile phone was launched in China market on September 16th. Apple retail stores are overcrowded, some models have been sold out, and some people even blatantly resell mobile phones.

　　Although only pre-booked "fruit powder" can buy mobile phones in physical stores, there is still a long queue in front of Apple retail stores.

　　The Apple retail store in Sanlitun, Beijing, was full on September 16th. In addition to the "fruit powder" that came to buy mobile phones, there are many interested customers who gathered around the display stage to see the true content of iPhone 7.

　　The "piano black" iPhone 7 is the most popular, and even the "scalper" who sells mobile phones at the door of Apple retail stores is hard to find. The price offered by "Yellow Cattle" is much higher than the official selling price, even reaching 10,000 RMB. The official price of "Piano Black" iPhone 7 in China is 6188 yuan, and the official price of the highest configuration of iPhone 7 Plus is 7988 yuan.

　　Information photo

　　Xu Liping, a special aerospace technician, is a powder shaper in the combustion chamber of solid rocket engine in 7416 Factory of the Fourth Research Institute of China Aerospace Science and Technology Corporation.

　　Since he joined the work in 1987, he has been engaged in the extremely dangerous micro-shaping work of the solid power fuel surface of the space engine, which is called "working in the explosive pile". Over the past 30 years, Xu Liping has been praised as "a great craftsman who carves gunpowder" because of his exquisite skills, professional attitude and dedication, and has been awarded the honors of "Top Ten Touching People", "Model of Sanqin", China Skills Award, National May 1 Labor Medal and "Touching China" in 2015.

　　"Plastic experts" in dangerous positions

　　Solid rocket engine is the "heart" of missile weapons and equipment. The size and accuracy of the burning surface of engine propellant directly determine the flight trajectory and precise range of the missile. Burning surface shaping is still a worldwide problem, and no matter how sophisticated the machine is, it still cannot completely replace labor.

　　In 29 years, more than 10,000 days and nights, Li Xu Ping and his colleagues have been doing one thing attentively, "micro-shaping the engine powder surface, and finely trimming the solidified propellant powder surface with special tools according to the technological requirements to meet the various complex requirements of missile flight."

　　Xu Liping’s work requires extremely high accuracy, "and compared with accuracy, the high risk of this position is even more daunting". He said that the particularity of solid fuel makes the operator lie on the explosive bag during plastic surgery. Once the cutter accidentally touches the metal shell or the friction is too large, it will cause combustion or even explosion in an instant. At a high temperature of several thousand degrees, the operator has no chance to escape safely.

　　"In 1987, I was less than 19 years old. After graduating from a technical school, I went to work in the charge shaping workshop where my mother once worked. Although I was fully prepared, I was stunned by the huge roar and mushroom clouds in the first class. I didn’t expect it to be so dangerous," Xu Liping recalled.

　　This class left a deep memory for him. From then on, he made up his mind that to avoid danger, he had to be bold and cautious and practice the knife in his hand.

　　Because the solid powder has strong toughness and contains coarse particles, it is difficult to grasp the force of using a knife. If it is cut across the board, it is difficult to keep the powder surface flat. Once it is cut too much or left with a knife mark, the powder surface accuracy does not match the design, and the powder cannot burn according to the predetermined direction, resulting in the engine deviating from the track and even exploding. The surface of the medicine is uneven, and how much to cut with a knife each time depends on the judgment of skilled personnel. In order to practice kung fu on his hands, Xu Liping kept pondering and practicing how to use force and how to cut the knife, gesticulating with basic skills such as cutting, cutting and shoveling, trying to figure out the cutting amount, cutting angle and cutting force of the knife, and his arm was sore. He was even more meticulous in his post operation, humbly asked for advice, and studied hard and practiced one knife at a time. Over the years, he practiced more than 30 knives, but his hands felt more and more, and the smoothness of the medicine surface was getting higher and higher. Later, when he touched it with his hand, he knew how to trim the medicine surface that met the design requirements, and the products after his plastic surgery maintained a 100% qualification rate.

　　An innovator in the first-line workshop

　　Due to the needs of national defense construction, the fuel used in space solid rocket engines is getting higher and higher in energy. One expert described the risk as follows: "With a small steel ball rolling half a meter along the powder surface, these highly sensitive gunpowder will be ignited, and its burning temperature can reach thousands of degrees."

　　How to better improve the cutting tool, improve the plastic efficiency and ensure the safety is a problem that Xu Liping has been thinking and studying. He secretly vowed to develop a more useful and scientific cutting tool to avoid danger.

　　After continuous exploration and practice, he designed, manufactured and improved dozens of tools according to different types of engines, different stages and different parts of plastic surgery, of which nine applied for national patents, two were authorized, one won the Innovation Award of Shaanxi National Defense Science and Technology Industry Workers, and the other was named "Flat Knife" by the unit, which greatly improved the work efficiency and ensured the operation reliability and quality stability.

　　Since 2005, although it can’t completely replace manual operation, the factory has been trying to introduce and popularize advanced numerical control technology. For this reason, the factory has introduced the largest vertical shaping machine in China. However, there is no experience to learn from in applying such advanced technology to drug surface shaping, and the process of familiarity and use is far more difficult than imagined.

　　Xu Liping participated in the equipment installation from the beginning. "According to his years of work experience, he put forward more than 20 suggestions for modification, such as modifying the chip suction device and installing the interlocking device, and compiled the shaping program of the shaping machine to make the equipment performance better meet the post requirements."

　　Through unremitting efforts, Xu Liping gradually explored the shaping parameters suitable for all kinds of burning rate propellants, and designed special shaping tools for special profiles. The successful application of numerical control shaping machine under his leadership in the shaping process of propellant surface has filled the gap in China.

　　A fearless pioneer at a critical moment

　　Choosing a plastic surgery post means choosing to associate with danger and keep company with death.

　　"On one occasion, a key engine in China entered the critical stage of development, and two engines failed in the test run in succession, and another engine about to be tested was once again debonded." Xu Liping recalled that in order to thoroughly investigate the reasons, the expert group resolutely decided to dig drugs on the spot and look for the "root cause" without advanced testing equipment.

　　Digging medicine on the spot means drilling into the engine combustion chamber that has been filled with strong propellant, and digging out the solidified explosives, and the amount of digging medicine is extremely large, which is the first time in the history of the factory. It is difficult to imagine, and the danger is self-evident.

　　However, without any hesitation, a commando team with an average age of early 30 years old quickly formed. The leaders of the institute and factory were the first to drill in to check the situation, the experienced team leader drilled holes to find out the location, and the workshop director became the "first operation". Xu Liping also volunteered to join in and became the youngest commando.

　　Narrow space, half lying and half kneeling in tons of explosives, endured the strong and pungent smell, and the commandos carefully dug with wooden shovels and copper shovels. The high tension and lack of oxygen make each person only work in it for more than ten minutes at a time. As the youngest commando, Xu Liping always insisted on a few more minutes every time he went in. "At that time, in addition to the rustling of medicine, he could hear his nervous heartbeat."

　　In this way, like ants moving, it took more than two months to dig out more than 300 kilograms of propellant, successfully found the cause of the failure, and the repaired engine ground test was a complete success. After the task, Xu Liping’s legs were so painful that he could hardly walk. "As long as the organization and the task need it, I will still not hesitate to go to the ground!"

　　Cctv news(News Network): According to the data center of the Ministry of Culture and Tourism, during the National Day holiday this year, there were 422 million domestic tourism trips, and the domestic tourism income was 287.21 billion yuan. A total of 10,801 A-level tourist attractions are open normally, accounting for 75% of the total A-level tourist attractions. Twelve excellent sports tourist routes and 128 national rural tourist routes have enriched the holiday tourism market.

Major literary and art performance groups are innovative, presenting various types of stage art works, including Minning Town’s Literature and Art in the Anti-Japanese War. Home-made films with the theme of "Wan Li’s Return" appeared in the National Day archives, playing an inspiring voice of the times.

　　CCTV News: Tissue paper and toilet paper, collectively referred to as household paper, are one of the just-needed products for living at home now. In fact, just 30 or 40 years ago, these professional household papers, especially tissue papers, were still high-end goods and rare goods in our lives. Of course, now that everyone has a good life, professional household paper has become a necessity of life, but a supervision and spot check by the relevant departments found that some household paper actually has a low level of hygiene.

　　Jiangsu Provincial Bureau of Quality Supervision recently conducted supervision and spot checks on tissue paper and toilet paper products. The results show that some tissue paper is produced with recycled raw materials, and some toilet paper is "unsanitary" and many other unqualified problems.

　　Li Xiaotong, inspector of Jiangsu Paper Printing Products Quality Inspection Station, said that there were 162 batches of samples of tissue paper and toilet paper in this supervision and spot check, including 99 batches sampled by production enterprises, 18 batches purchased by physical stores and 45 batches purchased by e-commerce platforms. All samples involved 112 brands of 101 production enterprises.

　　In this supervision and spot check, Jiangsu Quality Supervision Bureau entrusted Jiangsu Paper Printing Product Quality Inspection Station and Huai ‘an Quality Inspection Institute to conduct testing. Among the 162 batches of samples, there were 88 batches of tissue paper and 74 batches of toilet paper.

　　In the interview, the reporter noticed that in this supervision and spot check, the unqualified rate of tissue paper was much higher than that of toilet paper. Among the 35 batches of unqualified samples, 28 batches of tissue paper were used.

　　The content of tissue paper is a quantitative information that the manufacturer clearly shows consumers how many sheets of paper are contained in this package of tissue paper on the outer packaging of the enterprise. However, in this supervision and spot check, it was found that 13 batches of tissue paper were unqualified, which is what we usually call short weight and short weight. As you can see, there are 500 sheets of tissue paper labeled as Yiran brand in my hand, but after testing, there are only 132 sheets of tissue paper in this package, which is only about a quarter of the express value.

　　After testing, among 28 batches of unqualified tissue paper samples, there are 13 batches with insufficient internal capacity, which is the biggest problem found in this supervision and spot check.

　　Of the 13 batches of unqualified samples, 8 batches were sampled from production enterprises, including:Named "Meijiaxin" extraction embossed napkin produced by Nanjing Bairun Paper Co., Ltd.; Named as "Weiyi (Cocoa Elephant Series)" extraction paper towel produced by Nanjing Yuankuo Technology Industry Co., Ltd.; Known as "Yinsijie" natural bamboo pulp paper produced by Zhenjiang Minzhen Paper Co., Ltd.; Known as "Shunan" removable facial tissue produced by Zhenjiang Sunan Trading Co., Ltd.; Known as "Haoxiang" bamboo fiber tissue produced by Zhenjiang Haoxiang Paper Co., Ltd.; Known as "Qianfeng" handkerchief paper produced by Changzhou Yudi Paper Co., Ltd.; Named as "Jieshilian" removable facial tissue produced by Baofuda Sanitary Products Factory in Shang Hu Town, Changshu City; Known as Xuzhou Tianqiang Paper Co., Ltd. produced "Xuanzhu" removable facial tissue.

　　4 batches are purchased from physical stores, including nominal sentences."Merlot" extracted facial tissue produced by Rongshi Jingwang Paper Factory; Known as "Yiran" removable facial tissue produced by Jiangsu Yangzhou Yiran Paper Co., Ltd.; Named "Fang Yaxin" produced by Jinsheng Sanitary Paper Factory in Jiangning District, Nanjing, with 420 pieces of removable facial tissues in gold; Named "Yufeng" removable tissue paper produced by Nanjing Yufeng Paper Processing Factory.

　　1 batch purchased from e-commerce, nominallyExtractable facial tissue produced by Senli Paper Group Co., Ltd..

　　In addition to the lack of internal capacity, this test found that the second major problem of tissue paper is that manufacturers illegally use recycled fibers as raw materials.

　　According to the inspectors, the national standard for tissue paper stipulates that recycled fibers are not allowed, and native wood fibers or non-wood fibers must be used. The national standard of toilet paper allows the use of native wood fiber, non-wood fiber and waste paper fiber.

　　"This is not a party, it is simply ‘ Advertising conference ’ There are several programs mixed in "The meaning of the host’s existence is to read advertisements" and "The Lantern Festival without advertisements is comfortable to watch" … … In order to welcome the Spring Festival and Lantern Festival, CCTV and David have launched large-scale parties. The reporter of "Rule of Law Daily" recently browsed social media and found that for some parties, the audience frequently "spits" and a large number of advertisements have become the main "slots".

　　It is worth noting that a large number of advertisements are implanted in some parties, which has become a common phenomenon in recent years. Many netizens said that some advertisements even ran through the party and were repeatedly mentioned by the host. Too many advertisements greatly affected the viewing experience. "Waiting for the live broadcast in front of the TV set, I finally waited for the party, but the ubiquitous advertisements made it difficult to concentrate on watching, and it was very jumping."

　　The reporter learned that from the perspective of the party producers, advertising is directly linked to sponsorship funds, which plays a vital role in program production and star invitation. But too many advertisements have become a "crowd-out" move for the audience. How to balance the relationship between them? Is excessive product placement suspected of violating laws and regulations? Should the number of advertisements be limited? With these questions, the reporter launched an investigation.

　　There are too many advertisements in the party.

　　Affect the audience’s viewing experience

　　"After the singer finished singing, he was taken by the host to a rest area on the side of the stage, where not only the products and logos of a certain brand were placed, but also the advertisements of the brand were scrolled at the bottom of the screen. The host and singer brought out the brand advertising words in the form of chat, and the whole process lasted for 5 minutes. I am blinded by the whole person. " Ms. Liu, who works in Chaoyang District, Beijing, still remembers the advertisement at a party during the Spring Festival this year. "It’s my favorite singer. I wanted to continue listening to him, but I was forced to watch a long ‘ Advertising performance ’ 。”

　　In recent years, the placement of advertisements in parties, variety shows and film and television dramas is too blunt and excessive, which has gradually become one of the problems reflected by the audience. In this year’s New Year’s Eve party of a satellite TV, the advertisement of a home brand is eye-catching. The brand name always appears in the lower right corner of the screen, and there are huge brand pictures on both sides of the main stage. When the camera zooms in, it almost occupies half of the screen, and the red background is particularly eye-catching in the dim scene. In the following time, the host and guests talked about the room decoration one by one, and the host even introduced the sofa and massage chair beside him. After 3 minutes of introduction, the next program was reported.

　　Mr. Zhang, a citizen of Tianjin who watched the party, said that it was even difficult for him to focus on the program being performed, and he remembered who the sponsor was after watching the whole party, which seriously affected the viewing effect.

　　The reporter observed many parties through playback and found that there were a lot of advertisements implanted in each party. From the host’s announcement to the stage layout to the performance, the advertisements provided by sponsors are everywhere, and there are various forms: there are brand logo； that occupy almost the whole background board; There are also ubiquitous brand animations; There is also a long advertisement for the audience during the program.

　　Most of the party advertisements are not "solo" of a single brand. In a series of programs at a party, two hosts sat on the sofa, and the table in front of them was filled with products provided by major sponsors, including drinks, mobile phones, alcohol and health care products. The desktop was piled up, and the camera gave these products close-ups many times, and the limelight was even better than that of the hosts.

　　Advertising is overwhelming and pervasive, which directly affects the audience’s viewing experience. "One second I was still enjoying the song, and the next second I seemed to switch to the shopping channel. I didn’t want to miss the next program, so I had to sit through this embarrassing ‘ Episode ’ 。” Netizen Xiao Qing said. Not long ago, while watching the party, she posted on the social platform: "It’s not just the stage background that advertises, but an advertisement will suddenly appear in the host’s announcement, sketch and program, and even the actor star will start introducing the product. I think I can’t wait to put the product directly in front of me."

　　Yu Chen, who lives in Nanjing, Jiangsu Province, bluntly said that the significance of some parties at present is more like making money, and the audience’s feelings are not taken into account. The more advertisements are added, the more money the organizers will earn. "This obviously goes against the original intention."

　　"Poor product placement is hard to accept, and most advertisements on the market are too ‘ Simple and rude ’ Some advertising words give people the feeling that street vendors are shouting ‘ Big sale ’ People just want to run. Product placement is not completely forbidden, but should not arouse the audience’s disgust, and it is best to be compatible with the program ‘ Get on the track ’ 。” Yu Chen said.

　　The advertising party will win both sides.

　　The audience called for regulation as soon as possible.

　　It is worth noting that not only major parties, but also many variety shows and film and television dramas have a large number of advertisements implanted. Then, why do all kinds of parties and variety shows become what the audience calls "advertising conferences" and "sponsor competitions"?

　　Ms. Zhang, who works in an advertising company in Beijing, told reporters that the placement of advertisements is compulsory to a certain extent. Taking film and television works as an example, all kinds of advertisements inserted by sponsors will appear together with film and television works, and viewers cannot directly skip and watch them without advertisements. It is for this reason that many businesses are willing to promote their products in the form of product placement, and evening parties, popular variety shows and TV dramas have become the most preferred.

　　Ms. Zhang said that if advertisers want to implant advertisements in audio-visual programs, they must pay the corresponding advertising fees to the photographers, which can greatly alleviate the cost pressure in the production stage. "Every broadcast after the release of film and television works means the exposure of advertising brands in front of the audience."

　　According to insiders in the industry, the cost of a New Year’s Eve party, the cost of inviting stars, and the remaining venue fees, publicity fees, lighting and other expenses are also very high. In the era of "traffic is king", the traffic brought by popular star artists to the party deserves a lot of capital investment, which leads to the situation that major producers "rob people". In order to ensure that famous artists are invited, producers have to raise the salaries of artists, and advertising sponsorship has become the most convenient and efficient channel to "fill the hole". The organizers of the party should attract as much investment and sponsorship as possible to ensure other expenses. Sponsors invest a lot of money, which will inevitably require as many advertisements as possible to enhance their exposure.

　　The "win-win" situation between the advertiser and the party has made the audience a "victim". The lengthy brand introduction and ubiquitous product placement have made many viewers call on the relevant departments to regulate the proliferation of product placement.

　　Zheng Ning, director of the Law Department of the School of Cultural Industry Management of China Communication University, believes that the cultural industry should achieve the unity of social benefits and economic benefits, and put social benefits in the first place. The cost of TV evening is high, which requires a lot of funds. Advertising sponsorship is the main source of funds, so it is reasonable to insert advertisements appropriately. However, if there are too many advertisements or unreasonable links, the audience experience will be seriously affected and the word-of-mouth will decline, which will reduce social benefits and ultimately affect long-term economic benefits.

　　Optimize the form of advertising content

　　Improve the law to respond to concerns

　　Judging from the legal provisions, is there a "cure" for the excessive product placement?

　　Yue Qiang, a senior partner of Beijing Hairun Tianrui Law Firm, said that at present, China’s laws do not prohibit or limit the number of advertisements published by TV stations. The advertising law and other relevant laws and regulations mainly focus on the content of advertisements, but do not explicitly limit the number, time and frequency of product placement.

　　"Any advertisement needs to comply with the provisions of the Advertising Law. If it is suspected of false propaganda and infringes on consumers’ right to know and choose, it needs to bear corresponding legal responsibilities. Therefore, TV stations should do a good job in advertising compliance when deciding to broadcast advertisements. " Zheng Ning said that TV advertising is one of the main advertising channels and an important way for TV stations to generate income. Promoting the healthy development of TV advertising can not only ensure the audience to watch programs smoothly, but also help to purify the market atmosphere and guide the benign development of the market. How to purify and improve the atmosphere has become an urgent problem to be solved.

　　To this end, Zheng Ning suggested that advertising is the economic lifeline of the development of the TV industry, and moderate advertising should be allowed, but broadcasters should be legal and compliant, constantly optimize the content and form of advertising, enhance the audience experience, and seek new profit models at the same time. The competent authorities should also supervise the legal compliance of advertising.

　　Yue Qiang believes that the current proliferation of product placement has become an important issue that the audience has strongly reflected and needs to be paid attention to. In the advertising law and other relevant laws and regulations, it should be stipulated in what way and in what proportion TV stations and film and television media groups should publish advertisements as advertisement publishers, so as to better protect the legitimate rights and interests of viewers. At the same time, optimize the content and form of advertisements and enrich the content of programs. "Only high-quality TV advertisements can make the audience like and remember, and it is not easy to produce resistance."

　　"The quality of TV advertisements put in by many businesses in China is low, which leads to the audience’s resistance. To this end, advertisers should seriously think about it, constantly communicate with advertising companies, and comprehensively consider the characteristics of products, the connotation of brands, the general situation of the market, and the form of broadcasting, so as to produce high-quality TV advertisements. " Yue Qiang said.
