Literally, the word "autumn" consists of "valley" and "fire", indicating the maturity of five grains.

Autumn is the transitional season when the weather turns from hot to cold, and then from cold to cold. Beginning of autumn has arrived, but not in autumn.

The division of climatic seasons should be based on the "average climate temperature", that is, the local average temperature is below 22℃ for five consecutive days, which is the real autumn.
