Off-year is a festival that is second only to New Year's Day. Its origins are as follows: On December 23rd of the lunar calendar, people call it off-year and it is a festival to worship the kitchen god.
The custom of offering sacrifices to stoves has a long history. Kitchen God, in the Xia Dynasty, has become a respected god.
In the Analects of Confucius, which describes Kong Qiu's words and deeds in the Spring and Autumn Period, there is a saying that "it is better to be charming than beautiful". In the pre-Qin period, the sacrifice furnace was one of the "five sacrifices" (the five sacrifices were the five gods of sacrifice furnace, gate, line, household and thunder).
Ray is the land god. The other is doors, wells, households, stoves and lightning; Or lines, wells, households, stoves, thunder).
When offering sacrifices to the stove, you should establish a spirit and make a sacrifice with rich wine and food. It is necessary to display tripods, arrange water beans, welcome corpses and so on.
With obvious traces of primitive fetishism. Kitchen God himself has long been known as Yan Di and Zhu Rong.
Later, many statements were derived. After the prosperity of Taoism in China, the kitchen god was described as the mother god in Jing Shuo.
"People's residence. At twelve o'clock, be good at knowing human affairs.
Remember good and evil and their merits and demerits every month, remember their severity, play Cao Shen in the middle of the night and set his book. "Later developed into grandparents.
In different regions, Zhao Jun and his wife are played by different candidates, accompanied by popular local folklore stories. There are always different opinions on the dates of offering sacrifices to stoves in ancient times, such as the first month, April, May, August and December.
In the feudal society of China, various religions coexisted, and the number of gods reached thousands, which was respected by folk customs. Perhaps in order to simplify unity, facilitate memory and operation, the saying that Kitchen God goes to heaven once a month has evolved into going to heaven once a year.
And set the time at the 23rd of the twelfth lunar month. This day has become a traditional festival for offering sacrifices to stoves.
2. What is the meaning and origin of the red scarf?
The red scarf is a corner of the red flag.
In fact, the red scarf originated from the Russian Orthodox Church. Lenin led the people to a revolutionary victory in Russia.
At that time, the Orthodox Church was very powerful in Russia, and children would wear red scarves as identification marks in Sunday classes. After the victory of the Bolshevik Revolution, the Young Pioneers were established in Russia in order to strengthen the education of children. At that time, Russian society regarded the red scarf as a kind of glory, and Russia * * * (Bolshevik) regarded it as a symbol of the Young Pioneers, giving it a new meaning-a corner of the red flag.
The red scarf is a corner of the team flag. In fact, the red scarf has a long history and originated in Russia.
1February 922 13, the world's first young pioneers organization led by a working-class political party was born in Moscow, Soviet Union. The newly established Young Pioneers have no special signs.
At that time, hunger and difficulties were threatening the people of the whole Soviet Union, and the issue of the symbol of the Young Pioneers was not considered. Lenin's wife, Krupskaya, was very concerned about the growth of the next generation and suggested that the Communist Youth League design a sign for the young pioneers.
At a meeting to accept new players, the advanced female workers who came to attend the meeting untied their red triangle headscarf and tied it around the necks of young pioneers, encouraging them: "Wear it, don't defile it!" " It's the same color as the revolutionary flag! "The red scarf was born. The Significance of the Red Scarf Shortly after the birth of New China, on June19491kloc-0/3, China * * * entrusted the Communist Youth League to set up a national unified children's organization-China Children's Team.
1June, 953 was changed to Chinese Young Pioneers, referred to as Young Pioneers. The Young Pioneers inherited the fine tradition of the Youth League in the revolutionary war years and took the red scarf as their symbol, just like the Youth League in the past.
The significance is that the red scarf is dyed red with the blood of China people, which represents the painstaking efforts of countless heroes. The red scarf is a corner of the red flag, symbolizing the victory of the revolution.
The Young Pioneers' joining ceremony is: put your right hand and five fingers together and hold your head high, indicating that the interests of the people are above everything else. The red scarf is a symbol of the young pioneers.
The red scarf representing the corner of the team flag is dyed with the blood of revolutionary martyrs. Every young pioneer should not only wear a red scarf, but also use his own behavior to maintain the honor of the red scarf and add luster to it.
In other socialist countries in Eastern Europe and Asia, members of similar organizations of the Young Pioneers also wear red scarves. In the Democratic People's Republic of Korea, the habit of wearing a red scarf is not to wear it under the collar as in China, but to cover the collar and not to fold it along the long side.
In the German Democratic Republic, primary school students who have just joined the Young Pioneers wear green scarves first and change to red scarves three years later. Children in Cuba and China wear blue scarves in the first to third grades of primary school; Wear a red scarf above level 4.
At present, the countries with Young Pioneers are North Korea and Vietnam.
3. Questions and answers about common sense of life
1, can't I drink water that has been boiled repeatedly?
You can drink. Some people think that excessive nitrite will cause cancer if water is boiled repeatedly. In fact, although water does produce some nitrite after several times of heating, laboratory data show that the nitrite content of tap water is still far below the standard of good drinking water after several times of boiling. Don't worry about "nitrogen poisoning" and "carcinogenesis".
2. Does too much water increase the burden on the kidneys?
On the contrary, as long as the renal function and cardiac function are normal, encourage drinking more water. Drinking water is to replenish water. Everyone's physical needs and amount of exercise are different. You can drink 1.5 to 2 liters of water every day according to your own situation, and the urine color is bright yellow. Drinking more water can improve constipation, reduce uric acid, and the climate in winter is dry. Water can also moisten the mouth and throat.
3. Should the leftover food be cooled and put in the refrigerator?
Compared with "putting hot dishes directly in the refrigerator", when the temperature drops to the same temperature, bacteria will produce more bacteria in food. If it is stored in the refrigerator for a short time, the increased bacteria are still within the acceptable range. However, it is recommended to wrap the food directly in the refrigerator with plastic wrap, and don't wait until it is cold. This will increase the number of bacteria, but it will only increase the motivation.
4. Can plastic packaging be heated?
There are several types of plastic wrap, some of which can only be used to package foods at low or normal temperature, and some of which have better performance and can withstand the high temperature of microwave heating. Please check the "Temperature Tolerance" and "Scope of Application" on the package. As long as the plastic package is marked with "microwave heating", please feel free to use it.
5. Can't you eat eggs when you have a fever?
You can eat. It is rumored that eggs with high protein content will increase the body's heat when they have a fever, which is not conducive to the recovery of the disease. At present, there is no research to prove this statement. After eating, different foods will bring different calories to the body. But the extra calories from eating one or two eggs have little effect on body temperature.
6. Can red wine soften the cardiovascular system?
You can't. Many people think it can soften blood vessels, because red wine contains resveratrol and other ingredients. In fact, the content of resveratrol in red wine is not high, and drinking a little every day has no effect on oxidation and arteriosclerosis. The alcohol content of 12% to 15% in red wine can not be ignored. Many authorities, including the World Health Organization (WHO), explicitly oppose the use of alcohol to protect blood vessels or the heart.

Cut the dried tangerine peel into shreds, add a little rock sugar, and then simmer with low fire to make a thick orange juice, which can treat cough! It is best to eat after three meals. Scrubbing wooden and bamboo tables and chairs with residual tea leaves can make them smoother.
Dry the remaining tea leaves and spread them in a damp place to remove water; After the tea leaves are dried, they can also be put into pillowcases as pillow cores, which are very soft. Water is an indispensable and important substance for human survival. People can eat nothing for a day, but they can't drink water for a day. However, not all water can be drunk. The following five kinds of water will form toxic and harmful substances such as nitrite to a certain extent, which will cause certain harm to human body, so people should pay attention to it.
You can't drink seven kinds of water. First, aged water: commonly known as "stagnant water", that is, water that cannot be stored for a long time. Drinking this kind of water often will obviously slow down cell metabolism for minors and affect the growth and development of the body; Middle-aged and elderly people will accelerate aging; The incidence of esophageal cancer and gastric cancer is increasing in many places. According to the research of medical scientists, this may be related to drinking aged water for a long time.
Relevant data show that the toxic substances in aging water also increase with the increase of water storage time. 2. Thousands of boiling water: Thousands of boiling water refers to the water that has been boiled on the stove for a night or a long time, and the water that has been repeatedly boiled in the electric water heater.
Because this kind of water takes a long time to boil, the content of heavy metals such as calcium and magnesium and nonvolatile substances such as nitrite in the water is high. Drinking this water for a long time will interfere with people's gastrointestinal function and cause temporary diarrhea and bloating; Toxic nitrite can also cause hypoxia in the body, which can lead to coma, convulsion and even death in severe cases.
Third, boiler water: boiler water is leftover boiler water such as buns, especially boiler water that has been reused many times, and the nitrite concentration is very high. Drinking this water often, or cooking porridge with this water, will cause nitrite poisoning; Scale often enters the human body with water, and it can also cause digestive, neurological, urinary and hematopoietic diseases, and even cause premature aging.
Fourth, the water that can't be boiled: the tap water that people drink is chlorinated and sterilized. 13 A variety of harmful substances can be separated from chlorine-treated water, among which halogenated hydrocarbons and chloroform also have carcinogenic and teratogenic effects.
When the water temperature reaches 90℃, the content of halogenated hydrocarbons increases from 53 micrograms per kilogram to 177 micrograms, which is twice as high as the national sanitary standard for drinking water. Experts point out that drinking raw water increases the possibility of bladder cancer and rectal cancer by 2 1%-38%.
When the water temperature reaches 100℃, these two harmful substances will be greatly reduced with the evaporation of steam. If boiling lasts for 3 minutes, it is safe to drink. 5. Boil water again: Some people are used to boiling the remaining warm water in thermos bottles before drinking, in order to save water, coal (gas) and time.
But this "saving" is not enough. Because water burns and evaporates, nitrite will rise. If you drink this water regularly, nitrite will accumulate in the body and cause poisoning.
How to prevent carsickness 1 The carsick person takes Shangshi Zhitong Ointment 1 tablet one hour before taking the bus and sticks it on the liver and navel (called Shenque point). If you ride for more than one day, change to another post the next day.
Can effectively prevent carsickness. 2. Fasten your seat belt before getting on the bus to prevent internal organs from swimming excessively in the body, which helps to prevent carsickness.
3. There is a piece of ginger in your mouth. People who love carsickness should take a piece of fresh ginger with them and eat 2 pieces of fresh ginger before getting on the bus, which can greatly reduce carsickness.
Don't eat acute gastritis when you are sick: fried food, wine, pepper and glutinous rice. Cold: banana, orange, Lu Xun juice, ice, mutton, ginger duck, alcohol and tobacco. Chronic gastritis: cold food, sour fermented food and sweets. Cough: ice cream, orange, fried, roasted, spicy, peanut, wine and dessert: peanut, sweet potato and egg fermented. Heart disease: overeating, high cholesterol, salty food, rheumatoid arthritis: beer, bananas, meat, shelter from cold and rain, diabetes: sweet, wine, greasy, fried, high-calorie food, traumatic injury: pig's head, flesh and blood, vinegar, peanuts, sweets, bananas, beer, hypertension: salty food, egg yolk, animal viscera, cheese. Guava pregnancy: wine, tobacco, coffee traumatic periostitis: banana, bamboo shoots, wine, sauerkraut, pepper hypotension: celery, should go to bed early and exercise more, hemorrhoids and bloody stool: tobacco, wine, pepper, fried food, kidney disease: beer, soda, salted fish, dried bamboo shoots, pickles allergic constitution: (measles, eczema, asthma, allergic rhinitis) seafood. The content of physical education class in primary schools must be conducive to promoting the all-round development of students' bodies and effectively exercising and strengthening their physique.
First, choose the right venue. At present, the general school sports venues are mostly cement, such as basketball courts and volleyball courts. In fact, the playground paved with cement asphalt is hard and elastic. Jumping in this site run for a long time is not only easy to cause trauma, but also causes chronic damage to the human body.
Therefore, qualified schools should try to set up plastic venues. This kind of venue can protect students from injury, and schools without conditions try to keep soil venues and battlefields.
Second, it is very important to ensure the safety of equipment. The choice of equipment is very important for the safety of students. Schools should strive to gradually complete the equipment according to the requirements of the new curriculum. If the temporary conditions are limited, teachers and students can be mobilized to make their own equipment, but health and safety factors must be considered. It is necessary to ensure that unqualified equipment is not used, and bad equipment cannot be used.
Third, class notes 1. Reasonable selection of exercise load. The characteristics of physical education itself determine that physical exercise is the main feature, outdoor is the main place, and it is dynamic, which increases the difficulty of organizing teaching.
If students use instruments improperly or have too much physiological load, they are prone to injury accidents. 2. Strengthen physical education class's safety awareness.
Physical education class requires students' bodies to participate in activities directly. There are indeed unsafe factors and potential dangers in the activities. However, as long as we attach importance to protection education, organize classes well, teach correctly and scientifically, and strengthen protection measures.

Tips for using diesel The fuel used by tractors running forward with black smoke is diesel.
Ordinary diesel oil is an oil product that reaches a certain standard with petroleum crude oil as raw material and smelting technology. People often see light diesel oil marked with No.0, 10, No.20 and No.32, indicating that their freezing points are not higher than 0℃,-10℃, -20℃ and -35℃ respectively.
Suppose your car uses diesel as fuel. When using, different grades of light diesel oil should be selected according to different regions and seasons. Generally speaking, when the temperature is low, light diesel oil with low freezing point should be selected; On the contrary, light diesel oil with high freezing point should be selected, and the freezing point should be 5℃ lower than the local temperature.
Plug tips Why do most household appliances such as electric fans, washing machines and refrigerators use three-wire plugs? What is the difference between a three-wire plug and a three-phase plug? Three-phase electrical appliances refer to three different live wires, and the voltage between each two wires is 380 volts. They are generally used in power systems and are more common in industrial electricity consumption. Single-phase power supply is generally used in household appliances, and its three wires are live wire, neutral wire and ground wire. The voltage between the live wire and the neutral wire is 220 volts, so this is not three-phase electricity, and its plug socket is not a three-phase plug socket. The grounding wire is to ensure safety.
What if the tractor slips? Tractor is a very important agricultural machinery, which is very common in rural areas. If you look at the tractor tires carefully, you will find that there are many protrusions on the tires. The purpose is to increase the friction between the tires and the ground, so that the tractor is not easy to slip when working in the field. The weight of tractor is also related to friction. In the same case, the heavier the tractor, the greater the friction.
So when the tractor slips, it can be solved by increasing its weight. Because tractors and other agricultural machinery are powered by diesel, the high-concentration particulate matter emitted by them is suspended in the air for a long time and easily inhaled by human body, which has become one of the main pollution in the suburbs of cities.
Spicy food is poisonous. In daily life, people often encounter food spoilage. The process of food spoilage is the process of decomposition and change of protein, carbohydrate and fat in food, and its degree varies with different kinds of food, types and quantities of microorganisms and environmental conditions.
Usually, the deterioration of fat is mainly due to rancidity, which is a mutagenic pollution of food. Enzymes, ultraviolet rays and oxygen produced by microorganisms can decompose neutral fats in food into glycerol and fatty acids, and fatty acids can be further decomposed into peroxides and oxides, and then rancidity products such as ketones and aldehydes with special smells are produced, which is called "spicy taste".
Eating food that has been stored for a long time because it is unsalable can lead to poisoning. The main clinical manifestations are gastrointestinal symptoms, and some patients may have dizziness, headache, abdominal distension, diarrhea, abdominal pain, nausea, vomiting and other symptoms. With the development of economy and the progress of science, people are no longer satisfied with "eating enough", but advocate more scientific and multifunctional health food that is beneficial to human health.
What is functional food? European experts from the International Institute of Life Sciences said: "If a food can be convincingly proved to be beneficial to one or more functions of the body, and it has enough nutrition to improve health or reduce diseases, then it can be called functional food." Functional food and general food can provide basic nutrients necessary for human survival (the first function of food), and have specific color, fragrance, taste and shape (the second function of food).
However, functional foods contain a certain amount of functional ingredients (physiologically active substances), which can regulate human functions (the third function of food); Functional food generally has a specific scope of consumption (specific population), and general food has no specific scope of consumption. It should be pointed out that the research and development of functional food at home and abroad is still in its infancy, and its effectiveness needs further verification.
Nowadays, many advertisements are exaggerated, so consumers should not blindly listen to the propaganda of advertisements. Scientifically speaking, paying attention to a balanced diet at ordinary times, such as a diversified healthy diet composed of a large number of fresh fruits, vegetables, vitamins and crude fiber foods, regular living habits, timely and moderate exercise and a happy mood, is the fundamental guarantee of health.
With the increasing application of science and technology in agriculture, the fields and scope of agricultural engineering are becoming wider and wider. Such as agricultural water and soil engineering, agricultural mechanization and automation engineering, agricultural electronics and information technology, post-harvest processing and treatment engineering of agricultural products, facility agriculture and environmental control engineering, rural energy, agricultural waste treatment and environmental protection engineering.
Modern agricultural engineering not only creates production benefits far higher than traditional agriculture, but also shows exciting agricultural production prospects. With the help of advanced engineering technology, people can not only see tomato trees bearing tens of thousands of fruits, but also see tractors equipped with air conditioning, computers, GIS, GPS and rs systems being used for fixed-point formula fertilization and fixed-point spraying weeding in the field.
Energy is closely related to human development. People have long known that energy can neither be created nor destroyed. So where does the energy come from? Energy exists in different forms and comes from different sources. We divide energy into two types: non-renewable energy and renewable energy.
Non-renewable energy resources refer to those resources that cannot be recovered in a short time once consumed, such as coal, oil and natural gas. According to the detection, if the current consumption rate is calculated, oil, natural gas and coal will be exhausted in 45 years, 60 years and 250 years respectively.
The opposite of "non-renewable energy" is "renewable energy", such as wind energy, tidal energy, solar energy and hydropower. These energy sources are inexhaustible, and they are also called "clean energy" because they have no pollution to the environment during use.
Because the non-renewable energy on the earth is limited, people should pay more attention to the generation, storage and transportation of renewable energy. The progress of human beings from ancient times to the peaceful use of nuclear energy today is actually a process of constantly absorbing and utilizing energy from nature.
Energy is closely related to people's lives, and energy shortage is a common problem at present. For example, some residents often complain that power companies limit electricity and electricity prices rise; Cars.

People eat fat not only because it can produce attractive fragrance, but also because it contains fatty acids needed by the human body and plays a nutritional role in the body. Its nutritional function mainly includes (1) providing energy; (2) Constitute human tissues (3) form components with physiological activity, and regulate physiological and biochemical reactions in vivo.
There are many kinds of fatty acids that form fat, which can be simply divided into saturated fatty acids and unsaturated fatty acids. It is generally believed that saturated fatty acids can promote the occurrence of atherosclerosis, while unsaturated fatty acids can prevent it.
In fact, there are dozens of food fatty acids, some of which participate in the formation of human tissue structure, some participate in the metabolic process, and some can regulate human physiological and biochemical reactions, all of which have certain effects on the human body. It is unscientific to evaluate them simply by "good" and "bad".
For example, we often regard cholesterol as a substance harmful to health, but cholesterol is an important substance for synthesizing bile, adrenocortical hormone, sex hormone and vitamin D, and only excessive cholesterol will cause harm to human body; However, we believe that DHA and EPA are beneficial to lowering blood lipids, but excessive amounts are also dangerous. Therefore, only a reasonable and balanced intake of various fatty acids is the guarantee of health.
Reasonable and balanced intake of fatty acids mainly means that the proportion of saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids in dietary fatty acids should be appropriate, and the proportion of n-6 and n-3 in polyunsaturated fatty acids should also be appropriate. The main way for people to ingest fatty acids is (1) to eat animal foods. Most of the fatty acids in animal foods are saturated fatty acids except fish. (2) Vegetable oil: The fatty acids in vegetable oil are mainly unsaturated fatty acids.
(3) complementary food: nuts such as walnuts, peanuts, melon seeds and fish containing EPA and DHA. In addition, other foods also contain a small amount of fatty acids.
In daily life, the intake of animal fat and other foods is generally fixed, while the types and consumption of plant fat are easily changed. Therefore, maintaining fatty acid balance can be achieved by adjusting vegetable oil. Vegetable oil is the main source of unsaturated fatty acids, but the fatty acid composition and proportion of each vegetable oil are different, and some of them are far from each other.
Consumers can alternately eat several kinds of vegetable oils for a period of time, so that the types and proportions of fatty acids ingested by human bodies are more in line with the needs of human health. However, alternating consumption can not accurately and quantitatively balance the intake of fatty acids.
According to the types and contents of fatty acids in China people's habitual diet, the producers of edible blended oil mix several kinds of vegetable oils, so that the fatty acids in vegetable oils are more balanced with those in food and meet the needs of human body. Therefore, fatty acid blending oil is a kind of.
