How did the solar terms in beginning of winter come about?

Beginning of winter, Changxia, beginning of spring and beginning of autumn are collectively called the four manors. China is an important festival in ancient society.

The solar term is the 19 of the 24 solar terms and the first solar term in winter. The arrival of beginning of winter indicates that our country will enter winter. Every year165438+1October 7 or 8 is the day of beginning of winter.

Beginning of winter is one of the twenty-four solar terms reflecting seasonal changes. In ancient China, beginning of winter was divided into three periods. The water froze from the beginning. It began to freeze the next day. After winter, there is less and less solar radiation in the northern hemisphere. At this time, there is still some heat storage on the surface in summer, so it is generally not too cold.

For the understanding of beginning of winter, we can't just stay in the sense of beginning of winter. The ancient people's understanding of opposition is the same as that of modern people, both of which mean establishment and beginning. But the explanation of winter is different. East means that all autumn crops are collected and put into storage. At this time, animals also hide and prepare for hibernation. So it's not just early winter. This also means that everything is to avoid the cold.
