What does the solar term in beginning of winter mean?

Stand still, build the beginning; In winter, everything will be collected in the end. In winter, when the sun goes down, it is cloudy and everything is harvested. Traditionally, "beginning of winter" is the beginning of winter, and the dry climate with little rain in autumn gradually passed and began to transition to rainy and cold winter climate.

After beginning of winter, the sunshine time will continue to shorten, and the height of the sun will continue to decrease at noon. Because there is still some energy in the heat stored on the surface, the temperature in early winter (Meng Dong) is gradually decreasing, but it is not very cold.

As time goes by, strong cold air frequently goes south and crosses Nanling, and the weather is getting colder and colder. In the north, it is already very cold before winter begins.

Extended data:

Before and after winter, precipitation in most parts of China decreased significantly. Northeast China is frozen, and agricultural and forestry crops enter the wintering period; The "Sanqiu" in the Jianghuai area is coming to an end; Jiangnan is busy planting late-season winter wheat and transplanting rapeseed;

On the other hand, South China is the best time to plant wheat in early winter. At this time, the water condition is closely related to the seedling growth and overwintering of crops.

However, due to the influence of global warming, parts of the south are still warm and pleasant. In North China and Huanghuai areas, the average temperature of the day dropped to about 4℃, and the soil in the field froze at night. When it disappeared during the day, we should seize the opportunity to water the winter water of wheat, vegetables and orchards to supplement the lack of soil moisture.
