　　"Iron Lock" Wu Hui

　　"Tiesuo" is Wu Hui’s nickname.

　　"Come on, little friend, come in!" Inside the cave, the educated youth whispered to Wu Hui outside the cave.

　　Wu Hui didn’t move, and he didn’t know what to say in rags. In fact, he is not a child, but he is thin and looks small.

Wu hui

　　That year, Wu Hui was 14 years old, only one year younger than the supreme leader. Before the arrival of educated youth, he had just returned to Liangjiahe from school. He is a junior high school student.

　　Wu Hui didn’t go in and stood at the door listening to them. He looked at the educated youth as if he were looking at a new world.

　　At that time, it was the cold winter and the weather was very cold, but the educated youth couldn’t burn the kang. The cave was as cold as icehouse. The educated youth asked Wu Hui outside the door if he would burn the kang. Wu Hui said, "Of course." In the countryside, which doll can’t burn kang? Wu Hui timidly walked into the cave.

　　In this way, Wu Hui became a frequent visitor in the cave of educated youth. The educated youth knew his nickname "Tiesuo", and he also remembered the names of six educated youth.

　　Wu Hui has seven brothers and sisters. The family has a large population and little labor. At that time, such families were the poorest in the countryside.

　　Wu Hui’s nickname "Iron Lock" hides a bitter story. Wu Hui once had a brother who died soon after his birth. Wu Hui was also sickly after his birth, so his parents asked the fortune teller to "keep the lock" for him, so he was nicknamed "Iron Lock".

　　"Keeping locks" is a custom in northern Shaanxi. When a child is weak and sick after birth, it is necessary to "protect the lock" to eliminate disasters and take refuge. Children who are "locked" and have a good family usually wear a silver lock; Ordinary people usually use 12 thimbles to string together as locks. This lock will be worn until the 12th birthday, and then an "unlocking" ceremony will be held.

　　Wu Hui is still very thin after the "unlocking". Although he was born in the countryside, it is difficult for him to adapt to the heavy labor in the countryside. Even if weeding is the lightest job for others, Wu Hui can’t stand it. He often ran to the ditch to sit on the pretext of relieving himself, and didn’t go back to work until the captain called him. At first, he earned 6 points like educated youth, and later improved, but never reached 10 points.

　　"Translator" Wu Hui

　　Wu Hui is small, but he is smart. He is happy to help educated youth and villagers eliminate language barriers. Wu Hui studied Mandarin at school, and the educated youth asked him if he didn’t understand Yanchuan dialect, so he became the "translator" of the educated youth.

　　The role of "translator" has added a lot of confidence to Wu Hui. Because they don’t live far from each other, Wu Hui comes to the educated youth whenever he has the chance. In addition to listening to the educated youth chatting, what attracts him more is the books placed on the kang platform, windowsill and pillow.

　　In 1973, the supreme leader and Beijing educated youth Lei Pingsheng (first from left), Tao Haisu (second from right) and Lei Rongsheng (first from right) were in Yanchuan County.

　　In the past few years at school, he has hardly read any extracurricular books except textbooks, and he has never seen so many books as thick as bricks. At first, he carefully picked up a book on the kang and looked through it page by page. When the educated youth saw that he liked reading, they said to him, "Take it if you like."

　　The first book he borrowed was 100,000 Why brought by the Supreme Leader. "How amazing it is to know a hundred thousand reasons!" Wu Hui My Sweetie in my heart, walking also look up.

　　This book opened a window for him to know the wide world. He was so hungry and excited that he couldn’t bear to let go. When he was hungry, he chewed bran dumplings and held a book, feeling that bran dumplings that were usually difficult to swallow were much better.

　　After reading 100,000 Why, he borrowed Romance of the Three Kingdoms, Mother, Quiet Don River and so on from the Supreme Leader. He began to have spiritual communication with the educated youth.

　　He felt frankness and frankness from Wang Yansheng and Lei Pingsheng, and low-key and pragmatic from the supreme leader. Wu Hui said: "I admire them. They are actually the coordinates of my life."

　　Wu Hui feels that it is reading that gives the supreme leader unlimited power. The supreme leader said: "There is a wider world and more knowledge in the book. Through learning, people will increase their knowledge and gain knowledge, and they will become stronger and stronger."

　　Under the influence of the supreme leader, Wu Hui swam in the ocean of knowledge and gradually strengthened his determination to go to college.

　　In 1973, he and the supreme leader entered the university together. The results came out, and he was admitted to Yan ‘an Normal School.

　　When Wu Hui went to school, the Supreme Leader gave him a 30-Jin food stamp, and took out a blue fur collar coat left by Wang Yansheng when he left Liangjiahe. He said to him, "Take this coat, and you can wear it at school and use it as a quilt cover."

　　Be a giant in action: President Wu Hui.

　　When Wu Hui graduated, the supreme leader had left Liangjiahe. Wu Hui was first assigned to the May 7th Middle School of Wen ‘anyi Commune as the teaching director, then transferred to the teaching and research section of Yanchuan County, and then went down to the grassroots level, successively serving as the education specialist in Chengguan Town, Wen ‘anyi Town and Yuju Township. But no matter where he goes, he asks himself to talk less and do more, and be a giant in action.

　　In 1970, the production team specially built 6-hole educated youth caves. The supreme leader moved there until he left in 1975. The picture shows the top leaders visiting Shaanxi in 2015.

　　In 1987, Wu Hui was transferred to the head of Yuzhong School. He didn’t expect Yuju Middle School to be completely different from what he imagined: the doors and windows of the classroom were tattered, creaking in the wind, garbage was piled up on the campus, weeds were growing, and bricks and gravel were scattered all over the floor … …

　　Wu Hui understands that this is the teacher’s heart is scattered and confidence is gone! This is parents’ disappointment with the school!

　　The new official took office with three fires, and Wu Hui’s first fire was to rectify the school order. He formulated strict discipline and took the lead in implementing it himself. The school gate, playground and classroom are all his supervision posts.

　　He stood at the school gate to see which teacher was late and which student left early!

　　He stood on the playground to see which class shouted loudly and which queue kept pace!

　　He stood in the classroom to see which teacher gave a wonderful lecture and which student raised his hand actively!

　　He stood on the rostrum of the teacher-student conference of the whole school, commending the advanced, rewarding the excellent, criticizing the backward and punishing the violation of discipline.

　　In less than a month, teachers and students can do morning exercises on time, reading in the morning sounds loud, the classroom is active, self-study is quiet, students are in formation after school, and teachers are energetic in class … … Yuju Middle School has finally taken on the appearance of a school.

　　Wu Hui knows that the key to measure the quality of a school lies in the quality of teaching. He set an example, set a benchmark, organized teaching observation, rewarded diligence and punished laziness, and the enthusiasm of teachers was mobilized, and the teaching work in Yuju Middle School quickly stepped on the right track.

　　In the second year, Wu Hui took a teacher to Yan ‘an Education Bureau to apply for a teaching building construction project, which was quickly implemented. Soon, a brand-new teaching building stood on the campus of Yuju Middle School. He ran to the township and county for support, equipped with teaching equipment, and the teachers and students moved into the new teaching building with joy.

　　Yuju Middle School has changed, both inside and outside. People say: "It is not easy for Yuju Middle School to be in the forefront of township middle schools in the county."

　　There are still many difficult things. In 1993, Wu Hui was transferred to the position of director of the Education Committee of Yongping Town, just as the county was paying close attention to the "sixth grade", requiring rural schools in towns and villages to have classrooms and desks and stools for everyone, and the enrollment rate must reach 99%.

　　Wu Hui told Yongping village branch secretary and village director: "It can attract social forces to join and improve the school’s running conditions."

　　On hearing this, Wu Hui, secretary of the village branch and director of the village, was right, so he and Yanchang Oil Company formed a co-construction unit and soon built a five-story teaching building, and Yongping Village passed the "sixth grade" pass.

　　According to the same idea, Yongping Town raised funds from various sources, and all schools achieved the "sixth grade" standard.

　　In 2000, Wu Hui was transferred to Yongping Middle School as the general manager. In the past four years, he worked with the school leaders to plan, run projects, find funds, coordinate and supervise, without stopping. An apartment building, a teaching building and a dining building have sprung up one after another … … Finally, Yongping Middle School was completely changed.

　　In 2014, Wu Hui retired. Before he left, he came to the campus alone, walking east and looking west, reluctant to leave.

　　"A man’s life should be spent like this: looking back, he will not regret for wasting his time, nor will he be ashamed for doing nothing … …” Wu Hui thought that he didn’t live up to the meaning of life!

　　On the morning of February 13th, 2015, the Supreme Leader visited the villagers in Liangjiahe Village, Wen ‘anyi Town, Yanchuan County, Yan ‘an City, and conducted field research on poverty alleviation in the old district. Xinhua News Agency reporter Lan Hongguang photo

　　　　On August 15th, China’s Tong Wen defeated the Japanese in the women’s judo final over 78kg at the Beijing Olympic Games? Tian Zhenxi, win the championship.

　　　　"Today’s game is very dramatic for me, but I have always believed that I will win this game!" Tong Wen, who staged a big reversal at the last minute of the game and won the 24th gold medal for China, recalled after the game.

　　　　The women’s judo competition over 78kg is the last and most important battle of the China judo team in Beijing Olympic Games, with Tong Wen playing against the Japanese team’s Athens Olympic champion? Tian Zhenxi. With eight seconds left in the game, Tong Wen was still behind his opponent in the score. However, she finally gave a shocking fall and broke the Japanese with a "book"? Tian Zhenxi’s dream of defending the title also helped China’s judo team to win the third gold medal in this Olympic Games.

　　　　"I fought for the honor of China," Tong Wen, who is cheerful, smiled like a flower. "I won not only for myself, but also for my motherland. As we all know, Japanese judo is the best. I want to beat her and fight to defend China’s female rouzheng 78kg class. "

　　　　The game is really very dramatic. Failure almost became a Japanese judo master? Tian Zhenxi, the mother of success, prepared for Tong Wen so carefully before the game that Tong Wen found out in the final that each of her favorite skills had not been given, and the other side had expected the enemy to be ahead, so she took precautions in advance.

　　　　Tong Wen patiently looked for opportunities, but his opponent "cunningly" defused Tong Wen’s attack. Moreover, her counterattack was also very effective, and she got an "effective", although Tong Wen later got an "effect". ? After Tian Zhenxi took the lead, he started a passive game. As the game passed, the audience at the scene was right. Tian expressed dissatisfaction. However, Tong Wen didn’t give up, but finally found the opportunity to kill. With eight seconds left in the game, he made a super turnaround and won a precious gold medal.

　　　　"The secret of my victory is my belief in winning," Tong Wen told reporters when he walked off the court. "I used to? Tian has never lost. This victory in adversity is a valuable life experience for me. It is an improvement for me to get up from adversity and win this time. In the past, I rarely lost points and won again. " Tong Wen hit so hard that the game ended for an hour. Tian Zhen had just recovered from his failure. "I realize now that she is indeed stronger than me. I personally didn’t feel that I made a mistake. "

　　　　The belief of winning and the ontological reaction made Tong Wen laugh at the end. For the competition, she concluded: "In the past, I basically won with’ one book’ in one minute. But I’m still behind with 20 seconds left in the game. I won by faith: I have never been afraid in the competition. I have never had the word’ fear’ in my mind since I was a child, only’ win’. "

　　　　This is Tong Wen’s first Olympic gold medal, but it is so impressive. "The first time I participated in the Olympic Games in Beijing, the last decisive battle was so dramatic. This Olympic Games is a wonderful memory for me, "she said.

According to a survey conducted by China Youth Daily, nearly 60% of the respondents feel that there are many "ineffective social activities" in their circle of friends. Setting the message not to disturb and the number of days that the circle of friends can be seen is the main way for respondents to "reduce the burden" on their circle of friends. To establish high-quality social relationships, 68.3% of the respondents suggested setting a sense of boundaries for social interaction in leisure time, and dare to refuse certain social occasions. 53.6% of the respondents suggested distinguishing social accounts of work and life and dividing boundaries for different social interactions.

Host language

Man is a social animal. Efficient and deep social communication and the division of labor and cooperation arising from it are second nature of human beings. However, the history of technological progress has always been accompanied by the process of opposing technological alienation. People invented the circle of friends, and suddenly found that it has increasingly become a performance social show. Returning to common sense and looking back at the initial heart may be more important than measuring the effectiveness of social interaction.

Youth theory

Low-quality social interaction is far less than high-quality solitude.

In the information age, it is difficult to avoid the "invalid" part in social interaction, because there is no guarantee that everyone you meet will not come and go in the future, and there will be no place to ask for help in the future. Therefore, it is the best way to maintain the circle of friends with painstaking efforts. Low-cost courtesy, praise from friends and mass holiday blessings have become the best way.　

The development of the Internet has brought convenience to social interaction, but the pervasive network has made social interaction lose its sense of boundary and brought invisible pressure. The circle of friends visible to everyone can no longer share their lives as they please; Most of the group chat messages that keep popping up have nothing to do with themselves, but they are afraid of missing important notices; I can’t get rid of the dinner and meaningless greetings, and I’m afraid of saying the wrong thing, which takes my brain and trouble. Modifying the visible range of friends circle, folding group chat, setting grouping and other functions came into being. These are silent resistance to ineffective social interaction and awakening of self-awareness. Instead of creating people to please others, they set aside boundaries for their own lives and pay attention to their own feelings.

Rejecting ineffective social interaction and focusing on your heart is the most important thing. Low-quality social interaction is far less than high-quality solitude. In fact, taking interests and hobbies as social orientation rather than benefits is not only relaxing and enjoyable, but also can actively learn and accept more things, so that social interaction can return to its own meaning. High-quality social interaction requires first determining one’s social goals and goals, choosing social scope, conducting social activities in a directional way, and focusing time and energy on important people and things in order to establish a deep social relationship with them. In addition, spending time in high-quality solitude is also a way to communicate with yourself. You are the one who knows your own advantages and disadvantages best. Examining and refining yourself is also an important way to improve yourself. (Liang Shuang Guangxi University for Nationalities Xiangsihu College, 2020 undergraduate)

"In 2023, the central power generation enterprises strengthened the management of thermal coal inventory, and the thermal coal inventory was always at a high level. The coal-fired generating units maintained safe and efficient operation, generating a total of 5.35 trillion kWh of electricity throughout the year, accounting for 52% of the national installed capacity and contributing 63% of the national power generation."

On January 24th, Li Bing, Deputy Secretary-General of SASAC, Director of Financial Supervision and Operation Evaluation Bureau and spokesperson, said at the press conference of the State Council Press Office.

This means that the proportion of coal-fired power generation in China has stopped the downward trend in recent years and returned to the level of 2019. From 2019 to 2022, the proportion was about 63%, 60.8%, 60% and 58.4% respectively.

The direct reason for the rebound in the proportion of coal-fired power generation is the increase in installed capacity and utilization hours of coal-fired power.

On January 30th, 2023-2024 National Power Supply and Demand Situation Analysis and Forecast Report issued by China Electric Power Enterprise Federation (hereinafter referred to as China Electricity Council) showed that by the end of 2023, the installed capacity of coal-fired power generation was 1.16 billion kilowatts, up 3.4% year-on-year, accounting for 39.9% of the total installed capacity.

Due to the drought in southwest China and the shortage of incoming water, the hydropower generation in power plants above designated size in China decreased by 5.6% in 2023. In the same period, the power generation of thermal power and nuclear power in power plants above designated size increased by 6.1% and 3.7% respectively.

According to the data of China Electricity Council, coal-fired power generation accounts for nearly 60% of the total power generation in 2023. "Coal-fired power is still the main power supply in China at present, effectively making up for the decline in hydropower output." China Electricity Council said.

In 2023, the utilization hours of power generation equipment in power plants of 6000 kilowatts and above nationwide were 3592 hours, down 101 hours year-on-year. Among them, hydropower was 3,133 hours, a year-on-year decrease of 285 hours; Thermal power was 4,466 hours, up 76 hours year-on-year.

In the past three years, the speed of coal-fired power approval in China has been accelerated.

In 2021-2022, the coal price in China rose sharply, and power cuts occurred in some areas, so ensuring supply became an important task for the coal industry. After that, the National Development and Reform Commission and other departments carried out various controls to optimize coal production and promote the approval and construction of advanced coal production capacity in an orderly manner.

According to Global Energy Monitor, a global energy monitoring organization, the amount of coal-fired power approved in China in 2022 is four times higher than that in 2021, reaching more than 106 million kilowatts, which is equivalent to approving two coal-fired power projects every week.

In 2023, China coal-fired power continued to be launched. Greenpeace’s Analysis on the Progress of Low-carbon Transformation in China Power Sector in the First Half of 2023 shows that in the first half of 2023, the total approved installed capacity of coal-fired power in China was 50.4 million kilowatts, accounting for 55.56% of the approved installed capacity in 2022, far exceeding the total approved capacity in 2021.

Last year, the installed capacity of wind power and photovoltaic in China increased significantly, but the contribution to the proportion of power generation was still limited.

According to the data of the National Energy Administration, by the end of 2023, the cumulative installed capacity of solar power generation was about 610 million kilowatts, up 55.2% year-on-year; The installed capacity of wind power was 440 million kilowatts, up 20.7% year-on-year.

Based on this calculation, the installed capacity of wind and light in China will be 1.05 billion kilowatts in 2023, which is about 38.2% higher than that in 2022, exceeding the predicted value of 1 billion kilowatts by China Electric Power Enterprise Association (hereinafter referred to as China Electricity Council) and accounting for nearly 36% of the total installed capacity.

Scenery has become the main source of the overall power installed growth in China. According to the data of the National Energy Administration, from January to November last year, the newly installed capacity of solar energy and wind energy was 205 million kilowatts, accounting for 72.5% of the newly installed capacity in China.

Although the installed capacity is gratifying, the wind power generation has not increased at the same rate. The National Energy Administration has not released the specific data of scenery power generation last year. In the first three quarters of last year, renewable energy accounted for about 49.6% of the total installed capacity, but the power generation accounted for only 31.1%.

Renewable energy includes non-fossil energy such as wind energy, solar energy, hydro energy, biomass energy, geothermal energy and ocean energy. Installed capacity refers to the sum of the rated effective power of the actually installed generator set, which is the theoretical upper limit of power generation; Power generation refers to the amount of electric energy generated by generator through energy conversion.

At the capacity market discussion seminar held by Greenpeace on January 25th, Yin Ming, director of China Power Project of Agora Energy Transformation Forum, pointed out that wind power generation is a kind of contractible power source with high installed capacity and low power consumption. Contraction power supply refers to those power supplies that have greater influence on the installed structure of power supply than on the generated structure, that is, high installed capacity and low generated capacity.

The conversion coefficient of installed power is the ratio of installed power generation to power generation. The larger the coefficient is, the smaller the influence of the change of installed power supply ratio on the change of power generation ratio is. As a contractible power source, the conversion coefficient of wind-solar power generation is greater than 1.

At the same time, Yin Ming said that in recent years, the conversion coefficient of installed capacity of wind power and photovoltaic has shown a downward trend, indicating that the influence of the change of installed structure of wind power generation on the change of power structure has shown a strengthening trend.

Alva Wang, a invited researcher at the 50-person Forum on Carbon Neutralization in China, pointed out at the meeting that the increase of new energy installed capacity has brought about an increase in power generation, but it has not brought about an increase in the effective capacity of the power system.

Capacity value refers to the power generation capacity that can be called by power supply to ensure the power supply adequacy of power system. Due to the low output of new energy guarantee, it can’t provide effective capacity, so it can only be replaced by electricity.

"If the electricity load increases, new energy can only provide electricity, and it still needs the corresponding installed support of traditional energy sources such as hydropower or coal power." Alva Wang said.

From the utilization hours, the utilization hours of scenery are lower than the average utilization hours of power generation equipment in power plants of 6000 kW and above in China.

Last year, the average utilization of power generation equipment in power plants with 6000 kilowatts and above nationwide was 3592 hours. Among them, the utilization hours of domestic grid-connected wind power are 2225 hours, up by 7 hours year-on-year; Grid-connected solar power generation was 1286 hours, a year-on-year decrease of 54 hours.

When it comes to cancer, everyone is familiar with it, even afraid! But do you know that in our life, there are also many culprits who cause cancer? Now let’s look at a case first:

Ms. Xu, who lives in Shanghai, was diagnosed with cancer last year, but what is even more frightening is that her husband, son and father all died of cancer.

What is the reason why a family has cancer and can’t escape the entanglement of cancer? The doctor conducted a lot of data analysis and found that the cause of cancer in Ms. Xu’s family turned out to be aflatoxin.

It turns out that there is a pepper tree in Aunt Xu’s home, which produces a lot of pepper every year, and Aunt Xu especially likes to eat pepper, which is indispensable for making pies, buns or cooking.

In fact, it is very difficult to store pepper. Aunt Xu will directly put away the pepper that has not been dried, so some pepper appears damp and moldy. Moreover, Aunt Xu is particularly frugal, and will continue to use moldy pepper. The doctor said that this is because the body ingested too much aflatoxin after eating moldy pepper for a long time, which induced cancer.

As early as October 2017, the World Health Organization compiled and published a list of four types of carcinogens according to their relevance to cancer. They are:

Class 1: it is a definite carcinogen for humans;

Class 2: limited evidence of carcinogenicity to humans;

Category 3: Suspicious carcinogenicity to human beings;

Class 4: substances that may not be carcinogenic to human body.

You know, there are 120 kinds of class 1 carcinogens! Today, Xiaobian has sorted out the categories that are closely related to our daily life:

01, wine and alcoholic beverages

The intermediate product of ethanol metabolism in the body is acetaldehyde, which can cause DNA damage or double-stranded breakage in cells, thus causing cancer. Ethanol is also a good solvent, and many carcinogens will be dissolved in ethanol. Some alcoholic beverages contain carcinogenic substances such as asbestos fiber, arsenic and nickel; Carcinogens such as polycyclic aromatic hydrocarbons (such as benzopyrene) may also be produced during the fermentation and distillation of wine and alcoholic beverages. Therefore, alcohol is an important risk factor for oropharyngeal cancer’s disease, laryngeal cancer, esophageal cancer, liver cancer, colorectal cancer and breast cancer.

02. Smoking

Cigarettes contain a large number of polycyclic aromatic hydrocarbons, phenolic compounds, formaldehyde and other carcinogens, which are important risk factors for lung cancer, laryngeal cancer, lip cancer, tongue cancer, oral cancer, esophageal cancer, gastric cancer, colon cancer, pancreatic cancer, bladder cancer, renal cancer and cervical cancer.

03, second-hand smoke

In the cold smoke exhaled by smokers, the tar content is twice as much as that in the hot smoke inhaled by smokers, and the benzopyrene content is twice as much.

04, processed meat (intake)

Pickled meat contains more nitrite and phosphate, while smoked meat contains polycyclic aromatic hydrocarbons (benzopyrene). It may induce a variety of cancers and is an important risk factor for colorectal cancer.

05. Chinese salted fish

A large amount of nitrite is produced in the pickling process, which is an important risk factor for inducing nasopharyngeal carcinoma.

06. Areca nut

Areca catechu has a lot of crude fiber, which will cause continuous damage to oral mucosa and lead to cancer. The alkaline substances and alkaloids contained in betel nut will destroy the cell membrane of mucosal cells and DNA of cells. It is an important risk factor for oral cancer.

07, outdoor air pollution

It is easy to cause lung cancer, and the risk of bladder cancer will also increase.

08, diesel engine exhaust

The tail gas contains hundreds of different compounds, which have been proved to be related to lung cancer and bladder cancer.

09, benzopyrene

A chemical substance found in coal tar, which is commonly found in automobile exhaust gas (especially diesel engines), smoke produced by burning tobacco and wood, and grilled food. It is a high risk factor for lung cancer, digestive tract cancer, bladder cancer and breast cancer.

10. Benzene

Paint, wallpaper, carpets, printers, automobile exhaust, synthetic fibers, building decoration materials, wood-based panel furniture and cigarette smoke all contain benzene. The products of benzene metabolism in human body will lead to the breakage and fragmentation of DNA chain and induce leukemia.

11. Formaldehyde

Ordinary people are mainly exposed to formaldehyde through artificial boards in newly renovated homes. It can cause nasopharyngeal carcinoma, neonatal malformation, childhood leukemia, Hodgkin’s lymphoma, multiple myeloma, myeloid leukemia and so on.

12, untreated or lightly treated mineral oil

Used for making hair cream, hair oil, hair wax, lipstick, facial oil, skin care fat, etc., and also used as food additive. It is a by-product of petroleum and contains a variety of hydrocarbons. Polycyclic aromatic hydrocarbons, heavy metals and other impurities may induce cancer.

13. Solar radiation

Excessive exposure, ultraviolet rays in the sun can lead to skin cancer.

14. Ionizing radiation (all types)

It mainly includes α-ray, β-ray, proton stream, neutron stream, X-ray and γ-ray. Ionizing radiation can induce various types of DNA molecular damage, thus causing cancer. May produce induced leukemia.

15. Hepatitis B virus (chronic infection)

Hepatitis B virus can cause DNA rearrangement and DNA fragment loss, and reduce the degradation ability of liver cells to other carcinogens.

16. Hepatitis C virus (chronic infection)

Virus core protein is closely related to liver cancer.

17, human papillomavirus

At present, more than 130 subtypes of DNA virus have been isolated, which are divided into high-risk and low-risk types, among which high-risk types 16 and 18 are the main types that cause cervical cancer.

18. Helicobacter pylori (infection)

Long-term settlement in the stomach will gradually destroy the gastrointestinal wall, which is a high risk factor for inducing gastric cancer.

19. Aflatoxin

It mainly exists in moldy grain, nuts and oil products. Eating food containing low concentration of aflatoxin for a long time is considered to be the main cause of liver cancer, gastric cancer and intestinal cancer.

20, estrogen-progesterone oral contraceptives (share)

It can induce liver cancer and increase the risk of breast cancer and cervical cancer.

21, painter, painter, painter, etc. (occupational exposure)

Pigments contain heavy metals such as cadmium, lead, mercury and chromium, and paints and organic solvents contain benzene and formaldehyde. Long-term exposure will increase the risk of cancer.

note:

The carcinogens mentioned above can cause some cancers, which refers to a possibility after long-term, excessive intake or contact. If you only eat a little occasionally, or touch it occasionally, don’t worry.
