China traditionally thinks that beginning of winter is the beginning of winter. The definition of "winter" in the 24 solar terms is: "Winter is the end, and everything is harvested", which means that the crops in autumn are harvested and put into storage, and the animals are hiding and hibernating. It seems that beginning of winter not only represents the coming of winter, but is complete. beginning of winter means that winter has begun, and everything is collected to avoid the cold.
