Understanding "beginning of winter" can't just stay in the sense of beginning of winter. Tracing back to the source, the ancient people's understanding of "establishment" 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 the crops in autumn are harvested and put into storage, and all the animals are 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.
