What does it mean to start making friends in autumn and winter?

In ancient times, people used to regard beginning of winter as the beginning of winter. At this time, the north wind started, the ground began to freeze, and the water began to freeze, which was also "sunny".

Beginning of winter is the19th solar term among the 24 solar terms. The ancient people's understanding of "ceremony" is the same as that of modern people, both of which mean establishment and beginning. But the word "winter" is not so simple. In the ancient book "Twenty-four solar terms", the explanation of "winter" is: "Winter is the end, everything is harvested", which means that all crops in autumn are harvested, collected and put into storage, and animals have been hiding and hibernating. It seems that beginning of winter not only represents the coming of winter, but completely speaking, beginning of winter means the beginning of winter, and everything is collected to avoid the cold.

In beginning of winter, there are three times to wait for the water to freeze: the water in this solar term can already freeze. The second place began to freeze: the land also began to freeze. When the pheasant enters the flood, it is a stork: the pheasant refers to a big bird such as a pheasant, and the stork is a big clam. After beginning of winter, big birds like pheasants were rare, but you can see big clams with similar lines and colors at the seaside. Therefore, the ancients thought that pheasants would become big clams in early winter.

Extended data

Twenty-four solar terms scientifically reveal the laws of astronomical and meteorological changes, skillfully combine astronomy, natural rhythm and folk customs, and derive a large number of related seasonal cultures, which have become an important part of China traditional culture. In order to express the characteristics of time series more accurately, the ancients divided solar terms into four groups according to climate and phenology: divided, arrived, opened and closed. "Fen" means vernal equinox and autumnal equinox, which was called "dichotomy" in ancient times; "Solstice" is the summer solstice and the winter solstice, which was called "the second solstice" in ancient times.

"Open" is beginning of spring and Changxia, "closed" is beginning of autumn and beginning of winter. Beginning of spring, Changxia, beginning of autumn and beginning of winter are collectively called "four calendars" and add up to * * * as "eight festivals". Folk call it "four seasons and eight festivals" or "eight festivals a year" In the long farming society, the 24 solar terms have played an important guiding role in farming activities and have rich cultural connotations.
