Does anyone know the origin of winter solstice? Who can tell the custom of winter solstice?

The origins and customs of the winter solstice are as follows:

First, the origin of the winter solstice:

1, the winter solstice coincides with the winter festival. In our calendar, the fifth grade, the third grade and the fifteenth grade are one section, and a year is divided into twelve sections and twelve gases, which are collectively called the twenty-four solar terms. Winter solstice is one of the twenty-four solar terms and one of the most important solar terms. During the winter solstice, the northern hemisphere gets the least solar radiation, which is similar to that of the southern hemisphere. A day is only about 9 hours, which is the shortest day in the northern hemisphere. On the contrary, it is the longest day in the southern hemisphere.

2. After the winter solstice, the altitude angle of the sun rises slowly, but this process is slow. The weather is getting colder and colder on March 9th. If there is cold air coming at this time, the weather will be even colder. After this time, the weather will gradually pick up. So there is an old saying in China, "It's cold in three or nine days".

Second, the custom of winter solstice: There are different customs in northern and southern China on this day.

1. Eating jiaozi in the north also has the custom of eating dog meat and mutton from the winter solstice, because after the winter solstice, the weather enters the coldest period. Chinese medicine believes that mutton and dog meat have the effect of strengthening yang and tonifying deficiency, and the folk still have the custom of tonic from winter to Sunday.

Eating jiaozi in the south is especially popular in Jiangnan. "Tangyuan" is an essential food from winter solstice, and it is a round dessert made of glutinous rice flour. "Round" means "reunion" and "perfection". Eating glutinous rice balls on the winter solstice is also called "the winter solstice group".

3. Sacrifice to heaven. According to documents, as early as the fifth year of Emperor Ding Yuan of the Han Dynasty, there was a custom of offering sacrifices to heaven from the winter solstice, which was gradually institutionalized in later generations. The ceremony of offering sacrifices to heaven is usually presided over by the "Emperor of Heaven", which embodies China people's reverence for nature and expresses their desire to pray for good weather in the world.

The solstice in winter symbolizes the rise of cathode and the growth of everything. This "ceremony of offering sacrifices to heaven" uses the past as a metaphor for the present, implying national rejuvenation and sharing happiness with the people.
