Which solar term refers to "beginning of winter, where everything is harvested to avoid the cold"?

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. The interpretation of "winter" in the ancient book "Twenty-four solar terms" is: "Winter is the end, and 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 the beginning of winter does not just mean the coming of winter. In a word, beginning of winter means that when winter begins, everything will be collected to keep out the cold.
