Introduction.
Our understanding of "Lidong" cannot just stop at the meaning of the beginning of winter. Tracing back to its origins, the ancients’ understanding of “Li” is the same as that of modern people, meaning establishment and beginning. But the word "winter" is not that simple. The explanation of "winter" in the ancient book "The Collection of Seventy-two Hours of the Moon Order" is: "Winter is the end, and everything is collected." It means that all crops in autumn have been harvested. After drying, they are stored in storage and the animals have been hidden for hibernation. To put it completely, the beginning of winter means the beginning of winter, the collection of all things, and the avoidance of the cold.
