The origin of solar terms in Xiao Man

Twenty-four solar terms: "In mid-April, things are small and full."

At this time, the seeds of summer sowing crops such as wheat in the north have begun to be full, but they are not yet mature, which is about the late stage of milk ripening, so it is called Xiaoman.

Agricultural proverbs in southern China give Xiaoman a new meaning: "Xiaoman is not satisfied with the broken ridge"; "Little people are full of discontent, regardless of mangoes." The word "full" is used to describe the amount of rain, and it is pointed out that if there is not enough water in the field when it is full, the ridge may crack and even rice cannot be planted when it is planted.

Characteristics of solar terms in Xiao Man

I. Meteorological characteristics

The arrival of Xiaoman solar term means that it has entered the rainy season of heavy precipitation, and the rain begins to increase, which often leads to continuous and large-scale heavy precipitation. For the northern region, Xiaoman is often the longest sunshine time among the 24 solar terms. Coupled with the dry air, the temperature in some places in the north can easily exceed that in the south. In the south, it usually rains a lot. Due to the active warm and humid air flow in the south, it meets the cold air from north to south in the south of China at the intersection of Huangchi and Jiao Jiao. At this time, there will often be sustained and large-scale heavy precipitation in South China, leading to heavy rain or torrential rain.

Second, the characteristics of farming

In the harvest season, early spring crops are about to be harvested, mid-season rice is sown in an all-round way, and farming is busy, and harvest is grabbed in sunny days and sowing is grabbed in rainy days. However, it is prone to dry weather in the small full season, "storing water is like storing grain" and "preserving water is like storing grain". We should not only pay attention to water storage and drought prevention, but also pay attention to rainy weather that may affect the harvest in Koharu. At this time, farming activities are about to enter the busy farming season, and the summer harvest crops are mature or close to maturity; Spring sowing crops grow vigorously; The autumn harvest crops will be sown soon.

Third, the phenological characteristics

Waiting for the bitter vegetable show: the "bitter vegetable show" on the day of Xiaoman, bitter vegetable, perennial compositae, blooming in spring and summer, bitter when feeling angry, edible when tender;

Second, weeds die: in the last five days, "weeds die". According to Zheng Xuan's explanation in the Eastern Han Dynasty, weeds are fine-leaved grasses, such as water chestnut grass, which blooms in March and bears fruit in April. Because it was born in Yin Qi, I was afraid that Yang Qi would die in summer;

Third, wait for the solstice of autumn: on the fifth day, summer wheat can be harvested.

How to maintain health in the twenty-four solar terms and the whole solar terms?

1, prevent skin diseases before they get sick.

Because of the hot and humid weather in summer, it is easy to breed mosquitoes and cause itchy skin or infection, so prevention is very important. This requires attention to family and personal hygiene. Change exposed bedding and close-fitting clothes frequently, and eradicate the "hotbed" where germs breed and spread in hot and humid weather.

2. Stay up late less to prevent getting angry.

Because after the solar term expires, the days are long, the nights are short, the temperature is high, the human body's metabolism is vigorous, the consumption is also large, and it is easy to get tired. If you stay up late for a long time, it will cause the disorder of people's physiological body and metabolic system, leading to excessive internal heat, which is easy to cause constipation, oral ulcer, sore throat and other symptoms of excessive internal heat.

Therefore, in this hot summer, we must deal with the internal and external heat together, and never let our body heat up. So go to bed early and get up early, and work and rest regularly. We can't stay up late

3, pay attention to food hygiene, prevent abdominal pain, diarrhea and other diseases.

In the full season, as the weather gets hotter, food tends to deteriorate and rot. "Illness comes from the mouth", so we should pay special attention to food hygiene. Try to avoid eating cold food, avoid eating overnight food, and stop drinking in summer to cool down, so as to effectively prevent abdominal pain, diarrhea and other diseases.

4, the temperature difference between morning and evening is large, and clothes should not be greatly reduced.

Although the temperature rises obviously after Xiaoman, the temperature difference between morning and evening is still large due to the increase of rainfall. So pay attention to the change of weather and add clothes in time. Especially at night, the temperature will still drop, and it will be a little cold, so cover yourself with a quilt when you sleep to prevent catching a cold, and pay attention to it when you go out in the morning and evening.

5. Ensure sleep time and take a proper lunch break.

In order to conform to the law that yang disappears and yin grows in summer, we should go to bed late and get up early. Of course, "staying up late" here is relative, not staying up late in the general sense. In order to maintain people's energy, the lunch break can be appropriately increased. But the lunch break should not be too long, it should be 15 ~ 30 minutes, which is more useful.

6, suitable for outdoor sports, more conducive to physical and mental health.

The weather is cooler in the morning and evening after Xiaoman Festival, which is more suitable for outdoor sports, and walking is the most suitable. In addition, playing chess, calligraphy, etc. It is also a good way to cultivate one's morality. In the summer after Xiaoman starts school, exercise should not be strenuous to prevent sweating from hurting Yin and Yang.
