Worried about the swing, left in my heart.

Autumn is one of the four seasons. In China, traditionally, "beginning of autumn" in the 24 solar terms is taken as the starting point of autumn. Entering autumn means that rainfall and humidity tend to decrease or decrease, and everything in nature begins to mature from lush.

According to the average climate temperature of modern scholar Zhang Baokun, there are four seasons in a year. The index is that the average temperature is lower than 10℃ in winter, higher than 22℃ in summer, and 10~22℃ in spring and autumn respectively.

Ancient poems describing autumn:

Travel in the mountains

Author Du Mu, Tang Dynasty,

As far away as Hanshan, the stone path is oblique, and people are in Bai Yunsheng.

Stop and sit in the maple forest late, and the frost leaves are red in February flowers.

Translation:

The stone path is crooked and oblique from the top of the mountain, and there are several families where the white clouds grow. I stopped the carriage only because I like the night view of Fenglin. Frosted maple leaves are better than bright February flowers.
