Does the reference to beginning of autumn in the calendar mean that autumn and summer have passed?

Don't! Oh! Don't get mixed up. Come on, let's study science!

Twenty-four solar terms can reflect the changes of seasons, guide farming activities, and affect the food, clothing, housing and transportation of thousands of households, which means that the division of twenty-four solar terms is mainly to let farmers know clearly what to do at this time!

Beginning of autumn is the season when everything is ripe and harvested. Every year in beginning of autumn, with the maturity of fruits and vegetables, Huangling entered the most prosperous season of autumn sun. After beginning of autumn, sunshine hours increased, which is a good time to dry crops.

"beginning of autumn" has arrived, not the autumn climate. 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. China is a vast country. Although the climate varies from place to place, most areas have not yet entered the autumn climate, and the last days of dog days are still the third day after beginning of autumn. Especially in the south of China, this solar term is still a hot summer. At the same time, because the typhoon and rainy season are about to pass and the temperature is even hotter, TCM calls the period from beginning of autumn to the autumnal equinox "long summer".

Therefore, the landlord, beginning of autumn solar terms, is to tell our uncle farmers that it is time to harvest rice! You can pick melons and fruits! It's not autumn! !
