"Life is too bitter. I really need this kind of funny drama to slow down. This is my favorite cooking drama recently." A Douban netizen commented on a costume love comedy "Qing Qing Daily" that was recently launched.

On November 16th, the peak content of "Qing Qing Daily" in the iQiyi station exceeded 10,000, making it the fourth series of iQiyi this year and the fastest series in the history of iQiyi. Since its launch, the drama has attracted more than 2,000 hot searches on social platforms, and it has caused heated discussions in Weibo, Tik Tok and other major social platforms. # Qingqing’s daily life seems to be a comprehensive collection of ancient costumes # # Qingqing’s daily electronic mustard tuber # # King Gigi plays a Neptune in Qingqing’s daily life # # Qingqing’s daily life is qingqing grasslands bar # and many other topics have been repeatedly searched, which has helped the drama break the circle successfully.

The "high opening and crazy walking" of "Qing Qing Daily" can not be separated from the "accurate" grasp of the taste of the mainstream audience, which gives a good emotional outlet to the audience surrounded by pressure and anxiety in real life with a relaxed and funny plot; At the same time, it also tells a story with modern social characteristics in the ancient background, and shows the true personality and emotional needs of contemporary women through the mouth of the women in the play, which has won many female audiences’ resonance.

Daily narration of anti-routine

Qing Qing Daily is adapted from the novel qing wear Daily by online writer Mu Muduo. The original work belongs to the representative work of "Farming Literature", which refers to a style of work in which stories mostly take place in underdeveloped periods and regions, focusing on describing trivial matters and psychological changes of small people in their lives.

In the process of adaptation, Qing Qing Daily abandons the Qing Dynasty background and crossing elements of the original novel, and retains the basic character setting and narrative style. For example, Li Wei, the heroine, is a poor girl with mediocre qualifications and no ambition. She only wants to eat, drink and live a good life every day. The emotional progress between her and Yin Zheng is not based on the two people experiencing "big winds and waves" together, but gradually warming up in three meals a day; In the play, the scene between Li Wei and his sisters-in-law is either cooking or eating. In addition, the drama also downplays the battle for power between Yin Zheng and the head of the office and the brothers, as well as the plot in the conflict between Xinchuan and other Sichuan provinces, which makes the drama more like intercepting a corner of life in the grand historical background. Such a plain, daily and light narrative method presents a slow life picture of "taking quiet in the middle of trouble" and gives the audience with fast-paced life a "decompression" experience.

The play is also full of many unexpected and innovative "anti-routine" plots. For example, in the audience’s cognition, the show girls who participated in the draft are generally well-known families, but the show girls sent by Ji Chuan are Li Wei because of her poor family and inability to deal with the relationship; Everyone’s mouth is charming and looks less than Pan An’s three masters, but the real person is Liu Guanlin, who was nicknamed "King Gigi" by netizens in "The Widowed Husband"; In the play, Yin Zheng was given a wedding and came home without saying a word. When there was about to be a conflict with Li Wei, the old servant’s "long mouth" spoke, which also made the audience straightforward.

In addition, the comedy’s punchline design is also very dense, and by constantly throwing stalks, shaking burdens, and creating funny scenes, it continues to give the audience the motivation to pursue the drama. For example, Li Wei mistook Yin Zheng’s "Book Examination Day" as the day of his death, so she not only marked "Widowhood Day" on her calendar, but also mentioned many times in her family letters: "My husband is going to die, an all-consuming love, I can come home as soon as possible." Even on the day of Yin Zheng’s book test, he held an onion in his hand to tear, and put on hemp for him, Dai Xiao. The plot setting full of jokes attracted the audience to laugh constantly, so "Qing Qing Daily" was called "electronic mustard tuber" by many viewers.

Female group images of "anti-female competition"

"It’s good that all women don’t love their husbands. Haha." This comment by a Douban netizen has won more than 800 praises.

As a costume drama that focuses on love, Everyday for Qing Qing does not follow the path of "seeing for ten thousand years and being in love for three generations" in most fairy tale dramas. I didn’t take the script of "step by step, breaking my love" in the traditional palace drama; Nor is it like "men and women pull and throw industrial saccharin to the limit" in the general sweet pet drama; In a light, daily and joyful way, it tells the story of the secret affection between men and women due to long-term coexistence, satisfying the audience’s psychology of "watching others fall in love the sweetest".

First of all, from the perspective of role setting, as a love drama in ancient costume, "Qing Qing Daily" takes the emotional progress of Ji Chuan’s poor scholar Li Wei and Xin Chuan’s six sons Yin Zheng as the main story, but it does not simplify the side story, but gives two young masters and their two wives, three young masters and their "twenty-five wives", five young masters and seven young masters a certain narrative space respectively. Therefore, " Such a role setting can, on the one hand, contrast and reflect the personality, characteristics and mode of getting along with each other from different angles; On the other hand, it also enriches the story and meets the audience’s demand for "one drama and more CP".

Everyday in Qing Qing also created a group of female characters with modern female consciousness. For example, Li Wei, the heroine, comes from Jichuan, which pursues equality between men and women and monogamy. Therefore, from the moment she stepped into Xinchuan, which pursues polygamy, she was waiting for her husband to return home, and she repeatedly threw out a modern view of equality between men and women in the play. However, Erhao, a woman who grew up in an environment where men are superior to women and was born in a common woman, chose to "abandon love" after witnessing the influence of marriage and childbirth on women’s status since childhood, and chose the most powerful husband as her owner, just to earn a good future; Shangguan Jing, the monarch of Danchuan County, who comes from a woman who is in charge of the family and recruits her husband’s wife, has a bold personality and a superb martial arts. She prefers to walk freely in the rivers and lakes than marriage. Before being "collected" by the three young masters, the girls in the twenty-four solar terms also worked hard for their livelihood. Such a female role with different personalities, sober human life and certain personality independence has won many female audiences’ welcome.

In addition, although the story in "Qing Qing Daily" mainly takes place in Xinchuan, where men are in power, there is almost no "female competition" bridge where women are fighting for favor and jealousy. On the contrary, the friendship of mutual help and mutual understanding among women is reflected everywhere. For example, Song Dance, who was secretly in love with Yin Zheng and opposed to Li Wei everywhere, was unfortunately chosen to marry and kiss, and Li Wei actively advised her to avoid kissing; When the girl in the twenty-four solar terms was punished by the three young masters, Li Wei and Yuan Ying went to the door directly to rescue her. This plot of mutual help between women can be seen everywhere in the play, which reflects the pursuit of independence, freedom and self-improvement by contemporary female audiences.

　"Modern" Narration by Metaphoring the Ancient to the Present

Another reason for the popularity of "Qing Qing Daily" is that it tells a story with modern social characteristics in the ancient background. This expression of borrowing ancient times to describe the present is closer to the living conditions of contemporary young people, which is more likely to resonate with the audience.

First of all, the characters’ personalities, ways of thinking and logic in Everyday for Qing Qing are all "modern people". For example, the seven young couples in the play are a couple who are "numb-headed" at the thought of communicating with others in social occasions. In the play, the two are in great pain because they need to prepare for the opening banquet, which shows the daily life of social fear to the fullest.

Secondly, the play also sets many topics that are also concerned by women in today’s society. For example, in order to avoid the situation of "being kissed" in Song dance again, Li Wei proposed to look at each other-a blind date in modern society-to find a husband for them, and in the process, he restored several common men in modern women’s blind date bureaus, such as Ma Baonan, a boastful "trustworthy man" and a greasy man with malicious intentions, which caused female audiences to smile.

Thirdly, under the historical background of overhead, the respective regions and cultures of "Jiuchuan" can easily remind the audience of the unique local customs of various regions in China, such as Danchuan, which likes to eat spicy food and is dominated by women, and most men are "raking their ears", which can easily remind people of Sichuan and Chongqing; Mo Chuan, which lives in the north, has strong troops and tough folk customs as a military fortress, can correspond to the three northeastern provinces and Inner Mongolia; Cangchuan, located in the northwest, full of deserts and rough folk customs, is more reminiscent of southern Xinjiang.

All these settings make Qing Qing Daily more like a modern drama in a costume. From the explosion of Qing Qing Daily, it can be seen that young audiences have new requirements for novelty, interest and richness of roles in costume love dramas. Qing Qing Daily has also made some innovations in the content category of costume love dramas: it can make people move, not only the wind and waves, but also the love of the two.

However, at the same time, Everyday for Qing Qing also has some relative regrets. For example, at present, although there are many female roles and different personalities in the play, all their efforts to change their own destiny are ultimately invincible to the "husbands and godsons" under the oppression of imperial power and patriarchy. For example, the channels and directions for Li Wei and Yuan Ying to gain freedom in the play are based on the "good future" of six young masters. From this point of view, if it is not enough as a rebellious female group drama "Qing Qing Daily", but as a light and daily sweet drama, "Qing Qing Daily" is undoubtedly an excellent student.

　　From the original depiction symbols unearthed from Jiahu site to Oracle Bone Inscriptions, inscriptions on bronze, bamboo and silk characters, seal script, official script and regular script … … The cultural development history of the Chinese nation for more than 5,000 years is a history of the development of Chinese characters, and almost all the production and important development stages of Chinese characters occurred in the Central Plains.

It is the symbolic symbol of China Literature Museum. Crossing Zifang is the main road leading to the main hall, and there are 28 pieces of Oracle bone tablets on both sides, which contain two most representative elements in the Yin and Shang Dynasties — — Oracle Bone Inscriptions and bronzes.

　　The main museum of China Literature Museum is Xuanwen Museum. The concept of "post-modernism" is adopted, and the modeling is based on the image of a high-level palace building in Yin and Shang Dynasties, which is based on the word "Yong" in Oracle Bone Inscriptions, that is, a large (Taiyin) room is built on a rammed earth platform with four slopes.

In recent years, with the enhancement of public health awareness and the continuous construction and improvement of cycling trails, cycling has become a popular aerobic exercise. The late summer and early autumn is a good time to ride, and mastering the correct and scientific riding methods can better promote physical and mental health.

According to Liu Yulei, deputy director of the Department of Sports Medicine, Peking University Third Hospital, cycling can improve cardiovascular function, increase the contractility of lung muscles and lung ventilation, prevent brain aging, enhance limb coordination, help relieve psychological stress and anxiety and depression.

Liu Yulei said that the first thing to do is to choose the right car, especially to adjust the height and comfort of the seat. When buying a bicycle, you must choose a suitable bicycle according to your height, weight and body proportion, otherwise you will feel uncomfortable when riding a bicycle, and your movements will be uncoordinated and you will easily fall down. Beginners should first find the frequency that suits them, and then increase the amount of exercise. Ordinary people pedal 60 to 80 times a minute. There should be a 20-minute low-speed warm-up before each ride, and the body can sweat slightly.

Cycling posture is very important. When the cyclist leans forward excessively, in order to observe the road ahead, he must raise his head and lift his neck. This is a compulsive posture, which can cause tension in the neck muscles. The posture of over-flexion of the waist when riding a bicycle will increase the burden of lumbar intervertebral disc, which will increase the risk of lumbar muscle strain and lumbar disc herniation over time. Therefore, cyclists should pay attention to maintaining the correct riding posture, lower the upper body and slightly tilt the head forward; The arms naturally bend, which is convenient for the waist to bend; Reduce the center of gravity of the body to prevent the impact force caused by the car bumping from spreading to the whole body; Hold your hands lightly and forcefully, and sit firmly on the seat with your hips. When riding for a long time, you should pay attention to changing your riding posture and take a proper rest.

Experts suggest that exercise should be gradual, not one-sided pursuit of strength and speed. Some cyclists suddenly ride at high speed and long distance without long-term training, which is very harmful to their health. In severe cases, it may lead to joint effusion, inflammation and even cartilage and meniscus damage. Some special people, such as patients with severe hypertension, high myopia and patients with severe joint diseases of lower limbs, are not suitable for cycling.

In addition, riding may have the risk of trauma and traffic accidents, so you should plan your route before riding, don’t choose bumpy roads, obey traffic rules, and wear a helmet to avoid brain trauma and fractures. (From China Sports Daily, August 23rd, 06 edition)

Inflammatory bowel disease (IBD) is a chronic disease that affects more than 6.8 million patients worldwide, mainly manifested as Crohn’s disease and ulcerative colitis. Patients suffer from abdominal pain, diarrhea and other symptoms for a long time. Because of its complicated pathogenesis, including heredity, environmental factors, intestinal microbial imbalance and abnormal activation of immune system, there is no radical cure at present, and traditional drug treatment has side effects and some patients have poor response. In a recent study published in Biomedicine & Pharmacotherapy, scientists screened a candidate molecule named KB-0118, which is expected to be used in combination with existing drugs to provide a more efficient and safe treatment scheme. BET family proteins play a key role in gene transcription regulation and have been used in tumor treatment before. However, the application of traditional pan-BET inhibitors is limited because of their high toxicity and short half-life, so the development of new BET inhibitors has become a hot research topic at present. This discovery provides a new hope for the treatment of IBD and other inflammatory diseases.

　　CCTV News:On the afternoon of the 7th, local time, a joint press conference was held by the government of Phuket, the Royal Thai Navy, the regional police station and the public health department of Phuket to inform the latest progress in the rescue of the capsized cruise ship in Phuket. The Thai side said that a total of 8 bodies of the victims were found that day. Up to now, the number of victims has risen to 41, and another 15 people are temporarily unable to verify their whereabouts. At present, 16 tourists from China have been confirmed dead.

　

　　At present, the accident is still being rescued, and the cause of the accident still needs to be investigated. However, it needs to be reminded that in recent years, island tour has become the choice of many tourists, but the ensuing wading safety accidents have risen rapidly, so how can tourists protect their own safety while enjoying the pleasant sea breeze?

　　Pay close attention to the weather and don’t take warning information seriously.

　　In the rainy season on the island, the changeable weather becomes a major cause of accidents. When participating in wading activities, we must pay close attention to the weather and not be lucky about the early warning information.

　

　　Hu Xiao, Meteorological Analyst, Public Meteorological Service Center of China Meteorological Administration: "If you come to tropical waters like Phuket in rainy season and go out to sea, and the weather forecast predicts thunderstorms, it can be said that there are certain risks. There is an obvious change in the weather. The weather is gloomy, the wind suddenly increases, or the tide suddenly changes, all of which tell us that we need to dock for safety, and we must not be lucky. In a word, it is very important to know the climate and weather in advance in this tropical country, and travel safety is the first. "

　　Pay attention to the risk of launching, and wear a life jacket.

　　

　 　 　　

　　When you are at the beach or swimming pool, be sure to walk together. Don’t go into the water alone without the supervision of a safety officer. When physical conditions do not allow, you should avoid wading activities. In case of stormy waves or red warning flags on the beach, you must not go into the water. Some sea areas seem calm, but in fact, the underwater undercurrent is swift and dangerous. In July, 2017, three male tourists from China went swimming in a private beach in Phuket despite the warning of wind and waves, resulting in two of them drowning.

　

　　Wang Yingxi, captain of the cave expert rescue team of Beijing Pinglan Public Welfare Foundation: "Always wear a life jacket when wading in the water to prevent accidents."

　　Diving needs to be carefully guided by professionals.

　

　　Snorkeling and deep diving are dangerous projects, and tourists who are old or suffering from heart disease, high blood pressure and other diseases cannot participate. If you take part in snorkeling projects, visitors must attend the training on the use of snorkeling masks in advance, and then go into the water after they can use them skillfully. Most importantly, you must follow the guidance of professionals when you participate in diving projects.

　　Wang Yingxi, captain of the cave expert rescue team of Beijing Pinglan Public Welfare Foundation"Don’t do actions that are forbidden by tour guides or diving instructors. China tourists are not familiar with the waters here, nor the sea and related dangers here."　

　　On July 1st, the Japanese government, which just finished the G20 reception, suddenly announced that it would restrict the export of three kinds of semiconductor materials to South Korea. According to Reuters’s report, Japan may impose this sanction as early as July 4th.

　　On the afternoon of the same day, the first official (deputy minister) of the South Korean Foreign Ministry, Zhao Seung-young, summoned the Japanese ambassador to South Korea and protested to him. South Korea’s Minister of Industry, Trade and Resources Cheng Yunmo said that he would consider resorting to the World Trade Organization.

　　According to the analysis of Nikkei Chinese Network, the semiconductor materials involved in this sanction are all materials for making TV and smart phone components. Japanese suppliers have an absolute dominant share in the market of these materials. Once the sanctions take effect, it will be difficult for Korean buyers to find alternative supply channels in the market, which will inevitably bring potential impacts to companies such as Samsung and LG in South Korea, and may also affect some Japanese manufacturers, which will have huge side effects in the long run.

　　At the moment when South Korea’s economic performance is not optimistic, how much impact Japan’s sanctions will have on South Korea’s economy has become a concern of many parties. According to Yonhap News Agency’s report on July 1, the Ministry of Industry, Trade and Resources of the Republic of Korea said on the same day that due to factors such as semiconductor and sluggish exports to China, South Korea’s exports in June decreased by 13.5% year-on-year to US$ 44.18 billion, showing a downward trend for seven consecutive months, and the decrease rate reached a new high in three years and five months.

　　However, there are also views that Japan’s sanctions are rare, but they are not intended to make South Korea "hurt." Hu Lingyuan, director of the Center for Japanese Studies at Fudan University, believes that this round of diplomatic turmoil between Japan and South Korea can be understood from the perspectives of historical issues between Japan and South Korea and their respective domestic politics.

　　Sanctions and countermeasures are still measured, but the business community has begun to worry.

　　In addition to the semiconductor industry, according to the Nikkei Chinese website, Japan also plans to remove South Korea from the "white list" of friendly countries in security protection in August.

　　According to the above report, Japan will strengthen South Korea’s export control in two stages. First, after July 4th, three products, fluorinated polyimide, photoresist and etching gas (hydrogen fluoride), are required to be licensed and examined separately. And it is planned to exclude South Korea from the "white list" of friendly countries in security in August.

　　According to the report, the list includes 27 countries including the United States, Germany and France, and South Korea will be the first country to be eliminated. If it is not on the list, the products that may be transferred to the military need to be approved by the Japanese Ministry of Economy, Trade and Industry when they are exported, and electronic parts, precision parts, machine tools, etc. are all controlled objects.

　　However, although the volume is not small, it seems that the leaders of Japan and South Korea have no intention of completely "freezing" the relations between the two countries.

　　"The semiconductor industry is not a particularly sophisticated field. Abe beat South Korea in this field and expressed his dissatisfaction, which can convey a kind of ‘ I’ll punish you for doing something wrong ’ The signal. It’s like having a bad breath. " Hu Lingyuan said.

　　Regarding the export control this time, Keisuke Yusheng Tian, executive director of Deloitte Management Consulting Company in Japan, said that "since it is an area where Japan can make its own judgment, it is estimated that it will not violate the rules of the World Trade Organization". However, Professor Fuyong Youxia of Waseda University thinks: "This is a measure in a gray area suspected of violating WTO rules".

　　"In fact, after Japan took the initiative to sanction, South Korea was a bit passive. It seems to be a loss to overthrow the agreement before, and South Korea’s domestic economy is not performing well now. In order to lose points, the Moon Jae in administration must fight back against Japan. " Hu Lingyuan analyzed that "South Korea will take some retaliatory measures, but it will be restrained. In fact, Japan’s sanctions are also moderate. Both sides have a deep concern for their domestic people ‘ Show ’ The ingredients will not really cause particularly deep harm to each other. "

　　In fact, many international factors also restrict the severity of Japan-South Korea bad relations. Japan has just finished the reception for the G20 Osaka Summit, and seems unwilling to be too "high-profile" when imposing sanctions on South Korea.

　　"The reason why sanctions are announced now is because Japan does not want this matter to affect the G20 meeting." Li Kaisheng told The Paper, "When all countries are opposed to the unilateralism of the United States, as the host of the G20, Japan does not want to affect its image because of sanctions."

　　"In addition, Abe can’t make Japan-ROK relations too rigid, and we must grasp the balance." Hu Lingyuan analyzed and said, "On the one hand, Abe wants to make some noise, but on the other hand, he can’t overdo it. In that case, it is difficult to score in China."

　　At the moment when the situation on the peninsula is easing, the factors of the United States and North Korea are also variables that cannot be ignored when the Abe government makes decisions.

　　"Abe must also take into account the feelings of Trump and Kim Jong-un. Trump just met with Kim Jong-un. In the context of the easing of the situation on the peninsula, Japan also wants to improve relations with North Korea. In Kim Jong-un’s view, Moon Jae in’s efforts to improve North-South relations are relatively positive. Under this circumstance, if Abe is too tough on South Korea, Kim Jong-un will not feel very happy. " Hu Lingyuan said.

　　However, the industry has begun to worry about the follow-up impact of sanctions.

　　According to the Nikkei Chinese website, the relevant person of SK Hynix said in an interview that the inventory was "less than 3 months". When asked, "If we can’t purchase more, will the factory stop production in three months?", the answer was "Yes".

　　Samsung Electronics evaded the specific instructions and only said that it was "investigating the situation in detail".

　　On the other hand, however, Korean companies have a high market share in the semiconductor field. In terms of semiconductor sales, South Korea’s Samsung Electronics topped the list, while SK Hynix ranked third. Especially in the storage semiconductor for data storage, Korean companies have strong advantages. A large Japanese electromechanical company is worried that "if the supply of storage semiconductors in South Korea stagnates, which will lead to a reduction in the production of Apple’s iPhone, it may also have an impact on the supply of parts and components of the company".

　　Sanctions have obvious symbolic significance, and both sides focus on internal affairs.

　　"Japan chose the semiconductor industry to start, which is mainly a symbolic act. It is not that Japan and South Korea will soon be in the semiconductor industry ‘ Go to war ’ Yes. " Hu Lingyuan told The Paper (www.thepaper.cn), "Abe’s action is first considered for the Senate election in late July."

　　The Senate election to be voted on July 21st is the first parliamentary election in Japan since the era of "making peace". Abe attaches great importance to this election. According to Xinhua News Agency, Abe’s Liberal Democratic Party is continuing to seek to amend Article 9 of the Constitution, so it regards constitutional amendment as one of the focuses of the Senate election. One of the highlights of the election is whether the forces supporting constitutional amendment can continue to maintain a two-thirds advantage in the Senate. However, Japan’s Kyodo News reported at the end of June that there are currently 78 people in the Senate who support constitutional amendment without re-election, and Abe still needs to win the support of 86 people to form a two-thirds advantage. Therefore, it is difficult to cross the threshold of constitutional amendment as it was three years ago.

　　In addition, just on the 25th of last month, Shinzo Abe just faced a cabinet no-confidence resolution jointly submitted by five Japanese opposition parties, including the Constitutional Democratic Party. Although Abe successfully "passed the customs" with the majority opposition from the people, the two parties and the Japan Reform Association, Abe will still face many uncertainties in the face of the decisive battle of the Senate election to be held in late July.

　　In this regard, Hu Lingyuan analyzed that the election campaign is about to enter a climax. If the election is very beneficial to Abe at that time, it is not excluded that he wants to "bundle" the elections of the Senate and the House of Representatives at the same time, further consolidate his domestic status, and even serve as the fourth prime minister. Therefore, Abe has the motivation to use his relationship with South Korea to do some articles.

　　In addition, Abe’s appointment in the diplomatic field has recently been incompetent, so he intends to score points in diplomacy and win the favor of voters. According to Hu Lingyuan’s observation, Abe’s diplomacy with China has been relatively successful recently, and other directions are all promising.

　　"The G20 is going well, but Japan-US relations are not optimistic. Trump also mentioned the Japan-US security treaty, and the United States is expected to put pressure on Japan after the Japanese Senate election. " Hu Lingyuan said, "Russia has also found it difficult to break through Abe, with Putin ‘ Make friends with ’ It seems that the trick can’t be played anymore. Therefore, Abe’ s diplomatic pressure is still relatively large. "

　　Abe is not the only one facing internal pressure. Moon Jae in’s South Korea’s economic performance was mediocre, and the economic growth rate showed a red light. On April 2 this year, the data released by the Ministry of Trade, Industry and Energy of the Republic of Korea showed that after the export data in February shrank at the fastest speed in the past three years, the total national export of South Korea in March was 47.11 billion US dollars, down 8.2% from the same period of last year, and fell for four consecutive months since December last year. On the 9th of the same month, the International Monetary Fund (IMF) predicted the list of countries whose economic growth rate will decline this year, and South Korea was among them.

　　"The Moon Jae in government is facing great pressure in the economic field. They promised to increase welfare, but the economic data is not optimistic at all. " Song Zhixun, a 27-year-old Korean youth, told The Paper, "If you lose points in diplomacy, it will be very unfavorable to Moon Jae in."

　　Japan and South Korea are not in a cold day, and Japan is suffocating.

　　In addition to the internal factors of the two countries, for the Japanese and Korean people, Japan’s rare sanctions are not completely unexpected. The two countries have been feuding for a long time because of historical issues, and they are deeply divided.

　　According to the Kyodo News Agency, a joint survey conducted by Genron NPO, a Japanese non-profit organization, and the Institute of East Asian Studies (EAI), an independent think tank in South Korea, from May to June showed that more than 60% of the respondents in both countries said that they thought the bilateral relations between Japan and South Korea had deteriorated, while only 6.1% of Japanese respondents and 3.7% of Korean respondents still thought that the relations between the two countries were "good".

　　Compared with the same period of last year, the proportion of Japanese respondents who thought bilateral relations were "bad" jumped to 63.5%, an increase of 23 percentage points, the highest level since the first survey in 2013.

　　Kyodo News analyzed that one of the main reasons for the deterioration of relations between the two countries is the position of the Supreme Court of Korea on wartime workers. Japan insists that South Korea gave up the right to claim compensation in the 1965 Basic Treaty between Korea and Japan, and Japan provided huge funds for "economic cooperation" to South Korea, including grants worth 300 million US dollars and loans worth 200 million US dollars over 10 years — — The total amount was 1.5 times that of the national budget of Korea at that time.

　　In this regard, Naiwang Muxia, a Japanese college student, told The Paper that South Korea could not forget what Japan did as a colony during World War II, but Japanese officials believed that it had provided economic compensation to South Korea after the war, so they did not want this history to be mentioned again. "Japan (the government) feels that we have solved this problem with money. If South Korea wants Japan to listen to their claims, let’s return the money to Japan first." Naiwang Muxia said.

　　The survey also showed that another reason for the rapid deterioration of Japan Maritime Self-Defense Force-ROK relations was the incident that a South Korean navy destroyer irradiated a fire control radar on a Japanese patrol aircraft in December last year. According to the survey, more than 60% of the respondents in Japan and South Korea expressed confidence in the version of events provided by their governments. The Japanese side called the incident an "extremely dangerous act" and lodged a solemn protest with the ROK. The South Korean side explained that this was a normal combat operation, not aimed at Japan.

　　Based on the above-mentioned disputes, during the just-concluded G20 Summit in Osaka, Japan, the leaders of Japan and South Korea did not hold bilateral talks, but only shook hands and took a group photo as the host and guest at the opening ceremony.

　　"The historical issue has dragged on for a long time, and Japan really feels that it has a bite in its heart ‘ Evil spirit ’ . The Japanese side feels that park geun-hye has signed an agreement with Japan on ‘ Comfort women ’ The agreement on the issue, but now South Korea does not recognize it. " Hu Lingyuan explained.

　　The Japanese government believes that South Korea’s reopening of the issue of forced labor by the Japanese army during World War II violated the Japan-South Korea Claims Agreement between the two countries. Suga Yoshihide, the Japanese Chief Cabinet Secretary, rejected the proposal made by South Korea on June 19th, saying it was "totally unacceptable".

　　"In Japan’s view, since there is an agreement between the two governments, it cannot be said that the government will overturn the agreement as soon as the people are emotional. This makes Abe feel very faceless. " Hu Lingyuan said.

　　"In fact, it is understandable that Japan is a country with strong self-esteem." Song Zhixun, a 27-year-old Korean youth, gave his own understanding of the deterioration of relations between the two countries in an interview with The Paper. "They (Japan) are jealous of us as everyone knows, and (Korea) is obviously a colony of the former (Japan), but many industries and even cultures, stars and movies are occupied by South Korea. It must feel bad."

　　"Regarding Japan-ROK relations, there are two levels of government and people." Song Yue, director of the Korea Institute of East Asian Studies, who conducted the survey, said. On the other hand, Yasushi Kudo, the head of Genron NPO in Japan, also said that although most people think that Japan-ROK relations have deteriorated, the general impression of another country is not so bad. "Both governments should admit that their people want to improve this relationship." Kudo Jing said.

　　"We will hate the Japanese government, but we won’t hate the Japanese, especially the young people have no opinions on the Japanese." Song Zhixun said. Speaking of the trade sanctions that Japan has just announced against South Korea, Song Zhixun believes that this unfavorable situation for both sides will not last long. "It’s just temporary. (Japan and South Korea) was originally an alliance. In fact, there will be no reaction (relationship) no matter how bad it is."

　　Today, with the rapid development of science and technology, rumors under the banner of science are also emerging one after another. Moreover, many rumors like to start with the health and safety issues that the public cares about, sensationalize and create panic. A few days ago, under the guidance of the Beijing Association for Science and Technology, the Beijing Association of Editors of Science and Technology Journalists and the Beijing website jointly released the platform of dispelling rumors, "stop rumors and seek true knowledge — — Top Ten in 2019 ‘ Science ’ Most of the rumors in the gossip list are related to health. This edition extracts some health rumors and their truth interpretation and routine analysis to set the record straight.

　　Keywords: 5G base station radiation

　　● Gossip:

　　Mobile phone base stations have radiation, and 5G base stations are more than 4G, so 5G radiation will be greater than 4G, which is very harmful to human body.

　　● The truth:

　　Radiation is actually a way of energy transfer. Network speed-up has nothing to do with base station radiation increment. Network speed-up depends not on enhancing the signal transmission power of communication base stations, but on expanding transmission bandwidth, just like widening highways. The same is true for 5G communication base stations. Moreover, the more communication base stations there are, the better the effect of mobile phone calls, and the smaller the electromagnetic radiation generated between mobile phones and base stations.

　　The earth itself is a large magnetic field, and electromagnetic radiation is generated by lightning, thunder and sunspot activity in nature. In life, radio stations, base station antennas, microwave ovens, computers, televisions, hair dryers, radios and other household appliances that are inseparable from people’s lives will also produce electromagnetic radiation. Generally speaking, the radiation of the hair dryer can reach 100 microwatts/cm2, and the radiation of the induction cooker can even reach 580 microwatts/cm2. The wireless router commonly used in the home also generates more than 60 microwatts/cm2 within 1 meter.

　　The electromagnetic radiation of communication base stations should be less than 40 microwatts per square centimeter according to the requirements of national standards. In the actual implementation, the operator should consider the signal superposition, and the project construction should be controlled within 8 microwatts/cm2. Therefore, whether compared with national standards or common household appliances, the radiation of communication base stations is very small and will not cause harm to human body.

　　● Routine:

　　New things, exaggerated.

　　This kind of gossip takes advantage of people’s ignorance of new things and exaggerates them, so that rumors can be widely spread.

　　● Similar rumors:

　　1.PX is teratogenic, carcinogenic and highly toxic, and the explosion is comparable to an atomic bomb.

　　Truth: PX has a long history. It is a widely used low-toxicity chemical product and a raw material for medicine, perfume and ink.

　　2. Eating genetically modified food is childless, and Americans don’t eat it.

　　Truth: The safety evaluation of genetically modified food is much stricter than that of ordinary food, and the genetically modified food approved by the government is safe.

　　Keywords: high-speed rail radiation

　　● Gossip:

　　High-speed rail has had serious radiation problems since its birth, and the greatest harm to people is to destroy the female reproductive system and cause infertility.

　　● The truth:

　　Trains running on high-speed railways in China generally use 25,000 volts and 50 Hz alternating current. Accordingly, the high-voltage power equipment of high-speed rail radiates the electric field and magnetic field in this frequency band, which is "extremely low frequency electromagnetic radiation", belonging to non-ionizing radiation and will not affect women’s fertility. The statement that "high-speed rail radiation seriously causes infertility" is purely misleading.

　　Where there is electricity, there is radiation, ordinary trains and subways have radiation, mobile phones and razors have radiation, and sunlight also has radiation. As long as the radiation is within a safe value, it will not affect people. The International Commission on Non-ionizing Radiation Protection stipulates that the safety standard of magnetic field radiation generated by high-speed rail is below 100 micro Tesla (magnetic induction intensity unit), and the safety standard of electric field radiation is below 5 kV/m.

　　Professionals of Beijing Railway Department have specially measured the electric field radiation in high-speed rail cars and made the measured data public. The electric field radiation values of first-class cars, second-class cars, car joints, cabs and other positions of different models are distributed in the range of 0.011-0.021 kV/m.. Comparing these data, it is not difficult to find that the electromagnetic radiation of high-speed rail in China is far below international standards, and it is impossible to cause harm to human body.

　　● Routine:

　　Don’t talk about dosage, exaggerate the harm.

　　Alarming and exaggerating threats are the main characteristics of such rumors. Talking about radiation without dose has no practical significance in science. We have similar misunderstandings about many phenomena in life.

　　● Similar rumors:

　　1. Drinking coffee will cause cancer by ingesting acrylamide.

　　Truth: Acrylamide produced by high temperature in the process of making coffee is only potentially dangerous, and the content is very small. A person needs to drink at least 318 cups a day to have cancer risk.

　　2. The X-ray security instrument is harmful to human body.

　　Truth: The radiation of the security detector is far below the safety standard, so there is no need to worry about harm to the body.

　　Keywords: plague

　　● Gossip:

　　The mortality rate of plague is as high as 100%, and there is no cure. If you get infected, you will die!

　　● The truth:

　　Plague, also known as the Black Death, is a severe infectious disease caused by Yersinia pestis. According to different infection sites and clinical manifestations, plague can be divided into bubonic plague, pneumonic plague, septicemia plague, mild plague and other rare types of plague. Historically, plague did cause large-scale deaths, but it was because people didn’t know enough about the cause, treatment and prevention of plague at that time.

　　Although human beings are generally susceptible to plague, in modern medicine, plague is no longer hopeless. In fact, clinical plague cases can already be treated by standardizing the use of antibiotics. If patients can see a doctor early and get standardized treatment, the cure rate is very high, and suspicious contacts can also avoid getting sick by preventive medication.

　　However, it should be reminded that untreated plague patients have a very high mortality rate, such as the most dangerous pneumonic plague, which can be fatal within 18-24 hours of onset. If septic plague is not treated in time, the mortality rate is almost 100%. Therefore, early diagnosis and treatment are very important for patients to survive and reduce complications.

　　Gao Fu, academician of China Academy of Sciences and director of China CDC, said that at present, China has basically established a relatively complete prevention and control system. As long as it is scientifically responded, there will be no risk of widespread spread of plague.

　　● Routine:

　　In sensitive times, create panic.

　　Plague has caused heavy casualties in history, so related rumors spread rapidly when two cases of imported plague were found in Beijing. In the event of sudden events such as major epidemics and major disasters, people tend to be very sensitive and panic, and relevant rumors are easy to spread at this time. When dealing with extreme statements, we should develop the habit of questioning more.

　　● Similar rumors:

　　1. Sodium cyanide may cause toxic rain at the explosion site in Tianjin.

　　Truth: Solid sodium cyanide itself is highly toxic and can be dissolved in water, but it has no gaseous form in the conventional environment, so it is impossible to enter the air and spread with the wind, so there is no possibility of mixing with other components in the atmosphere and forming toxic rain by precipitation.

　　Smoking can prevent SARS.

　　Truth: It is recognized that smoking is harmful to health, one of which is to weaken the defense function of human respiratory system and increase the chance of infection. Besides, smoking also increases the contact between hands and nose and increases the chance of infection.

　　Eating iodized salt can prevent nuclear radiation.

　　Truth: The iodine content of iodized salt sold in the market is very low. In order to get the dose level required for the radiation protection of iodine, an adult needs to eat at least 2 to 3 kilograms at a time. Eating too much iodized salt or iodine tablets blindly according to the actual situation is harmful to the health and may cause diseases such as iodine exceeding the standard and iodine hyperthyroidism.

　　Keywords: thyroid nodules

　　● Gossip:

　　Detection of thyroid nodules is a precursor to thyroid cancer.

　　● The truth:

　　Generally speaking, most thyroid nodules are benign lesions, and real thyroid malignant tumors only account for a small part, so patients with thyroid nodules need not worry too much.

　　The diagnosis of thyroid cancer mainly depends on palpation, ultrasound, puncture and intraoperative pathology. With the continuous improvement of the resolution of modern ultrasound technology, more and more concealed papillary microcarcinoma of thyroid can be found, and most thyroid cancers can be cured through scientific and standardized treatment.

　　However, although there is no need to worry too much about thyroid nodules, we should not take them lightly. We need to go to a regular hospital as soon as possible for a definite diagnosis, so as not to delay the illness and miss the "golden time" of treatment.

　　In addition, because thyroid cancer usually has no obvious symptoms in the early stage, it is difficult to be detected. If there are symptoms such as sudden enlargement of nodules, dysphagia and adhesion of tissues near nodules, a comprehensive thyroid function test should be carried out to judge the nodules. Nodules that are difficult to distinguish should be examined regularly every 6 to 12 months.

　　● Routine:

　　Catering to demand, selling anxiety.

　　At present, people generally pay more attention to the topic of health and health preservation, but there are different opinions on online information, and some ambiguous rumors will take advantage of people’s psychological communication of "preferring to believe it, not believing it."

　　● Similar rumors:

　　1. There is rubbish in blood vessels, and if it is not cleaned up, it will be riddled with diseases.

　　Truth: There are no so-called garbage and toxins in blood vessels, but only metabolic wastes. Drinking plenty of water and increasing urination at ordinary times can help accelerate the cleaning of metabolic waste. In addition, any health food and detoxification soup can’t clear them out of the body.

　　2. Acidity is the root of all diseases.

　　Truth: The human body has an effective regulation system, which keeps the pH value basically stable and only fluctuates in a small range. In other words, eating any food will not change the pH value of the human body, and even drinking vinegar will not make the human body more acidic.

　　Keywords: artificial snow catalyst

　　● Gossip:

　　The large-scale snowfall in North China from February 13 to 14, 2019 was artificial snow increase. Silver iodide contained in artificial snow-increasing catalyst will endanger human health and cause environmental pollution.

　　● The truth:

　　In this snowfall, it is true that artificial snowfall has been carried out in some areas, but even if all the silver iodide catalysts used for snowfall have landed on the ground, the content of silver iodide per square kilometer is only 0.21g.. According to the precipitation, the silver ion concentration is about 0.000035 mg/L, which is far lower than the requirement of the World Health Organization standard and China’s national sanitary standard for drinking water that the silver content should not exceed 0.05 mg/L, and it will not pollute the ecological environment, and will not endanger human health.

　　As early as 1960s, scientific research institutions began to study the impact of silver iodide catalyst on the environment. The detection data of precipitation and soil after artificial rain and snow increase in the United States, Spain, Greece, Australia and Russia show that the average concentration of silver ions is very low. Therefore, the adverse impact of silver iodide, a catalyst used for weather modification, on the ecological environment can be ignored.

　　● Routine:

　　Technical terms lead to misinterpretation.

　　It is a common routine to take for granted the explanation of professional words that the public can’t understand, and spread it by taking advantage of people’s vanity that "I know more than you". Many people simply don’t know what "silver iodide" is, so they naturally believe and spread such rumors.

　　● Similar rumors:

　　1. Domestic salt contains potassium ferrocyanide, which is as toxic as arsenic.

　　Truth: Potassium cyanide is a well-known toxic substance, which is not the same as potassium ferrocyanide contained in salt. Potassium ferrocyanide is a low toxic substance, and a person needs to eat three or two salts a day to have a negative effect on the human body, while the salt that we normal people eat a day is already very salty when it reaches 20 grams.

　　2. Cereal contains pesticide glyphosate, which can cause cancer.

　　Truth: Scientific research shows that glyphosate has no negative effects on the development, reproduction and endocrine system of human beings and other mammals, and it has no chronic toxicity and neurotoxicity to animals in farmland within the scope of normal use.

　　Keywords: X-ray film

　　● Gossip:

　　X-ray has a great influence on human health, especially on pregnant women, babies and fetuses. Therefore, after taking the X-ray, I found that I was pregnant, so the child could not have it, and I had to have an abortion in time.

　　● The truth:

　　There is a threshold for the adverse effects of X-rays on all mammals, including humans, and even embryos. No matter for adults or fetuses, the radiation must reach a certain level to be damaged. Therefore, we can’t talk about the damage without the "dose" of radiation.

　　For the fetus, different gestational ages correspond to different safe doses of radiation. In 2017, the American Association of Obstetricians and Gynaecologists issued relevant guidelines: from 0 to 2 weeks of pregnancy, the threshold of teratogenic dose is 50 to 100mSv (millisieverts), and the main impact is fetal death; From 2 to 8 weeks of pregnancy, the threshold of teratogenic dose is 200mSv, and the main influence is congenital malformation; From 8 to 15 weeks of pregnancy, the threshold of teratogenic dose is 60 to 310mSv, which mainly affects mental development and deformity. Therefore, the threshold of the minimum influence dose of the fetus is 50mSv, which is safe as long as it does not exceed this value in theory.

　　In general, the radiation dose of an ordinary chest radiograph is 0.02mSv, that of a knee joint X-ray is 0.005mSv, that of a head CT is 2mSv, and that of a chest CT is 8mSv. Obviously, these radiation doses are within the safe range. To reach 50mSv is equivalent to 2,500 chest radiographs in continuous shooting, or 6 consecutive CT scans.

　　Many hospitals will take corresponding protective measures for those who are examined. For example, when taking a chest X-ray, the examinee will be put on a special lead hat and collar, and a heavy lead apron will be put around the waist and below to avoid unnecessary radiation to the human body.

　　● Routine:

　　Inertia thinking affects judgment.

　　In life, many medical institutions will remind pregnant women and pregnant people to avoid taking X-rays, which may make people form a "mindset", thus affecting rational analysis and judgment.

　　● Similar rumors:

　　1. The "grotesque" big strawberries are all hormonal.

　　Truth: hormones are substances that exist in plants themselves, and there is no need to talk about it. Most of the big strawberries on the market are "lucky" strawberries, which are very big in themselves. Some strawberries look strange, because the temperature and humidity conditions in the greenhouse are not good enough, and the lack of bees leads to uneven pollination.

　　2. Low outdoor visibility is caused by heavy pollution.

　　Truth: Atmospheric visibility is mainly affected by four factors: particle concentration, chemical composition, relative humidity and solar radiation. We often say that "air quality" only represents the concentration of particulate matter. In summer, the humidity of "sauna day" is relatively high, which significantly enhances the scattering effect of sunlight, resulting in a decrease in the amount of light input into people’s eyes, so the visibility is reduced.

　　Keywords: running

　　● Gossip:

　　People who run regularly are prone to hip and knee arthritis.

　　● The truth:

　　Risk factors leading to arthritis include age, family history, overweight and injury, but the length, intensity, distance and the number of long-distance runs completed have nothing to do with arthritis. In other words, people who are older, heavier, have a family history of arthritis or have had joint injuries are more likely to get arthritis.

　　Long-distance running does not destroy joints, but the proportion of marathon runners suffering from arthritis is lower than that of ordinary people. A large-scale study in 2017 showed that the incidence of arthritis in runners for fitness purposes was only 3.5%, while that in sedentary people was 10.2%. In other words, running can be a protective factor for the knee, and the key lies in the correct running mode.

　　In short, you should run within your power according to your physical condition. As long as the method is proper, it is beneficial to your joints and health.

　　● Routine:

　　Causality is confused and logic is misleading.

　　Misleading grafting causality. Succession or association is not equal to causality, and causality needs strict argumentation. It is a kind of thinking mistake that we often make to mistake the relationship of precedence or association for causality.

　　● Similar rumors:

　　1. Cold stimulation weakens the immune defense ability, and freezing can lead to arthritis.

　　Truth: By the age of 40, almost all people will have some pathological changes of osteoarthritis in their weight-bearing joints. Catch cold or catch cold is only an inducing factor that leads to the aggravation of arthritis symptoms, not a direct cause.

　　2. The woman in Xi ‘an died after being bitten by a dog and vaccinated, and the rabies vaccine was useless.

　　Truth: After the rabies vaccine is injected, there is indeed the possibility that the vaccine will be ineffective due to accidents, such as incomplete wound treatment and a small amount of virus remaining, but this does not mean that the vaccine is useless. In most cases, rabies vaccine is safe and effective.
