Today, we welcome the first solar term in autumn, beginning of autumn. Beginning of autumn is the thirteenth of the twenty-four solar terms. "Autumn" means that the summer is cool, and it also means that the crops are about to mature. Beginning of autumn is the beginning of autumn. It is crisp in autumn, clear in the moon and clear in the wind. Autumn is a transitional season when the weather turns from warm to cool. As the saying goes, "an autumn rain leads to a cold".
