Traditionally, China takes "beginning of autumn" in 24 solar terms as the starting point of autumn. The word "autumn" consists of the word "grain" and the word "fire", indicating the maturity of the five grains. After entering autumn, in nature, everything begins to mature from lush. Its climate began to change from rainy and humid in summer to dry and rainy in autumn.

The four seasons in China are often divided according to the change of temperature, using the "average temperature" of modern scholar Zhang Baokun. According to the weather average temperature method, there are two main criteria to judge autumn. First, the average daily temperature for five consecutive days 10℃-22℃ can be regarded as autumn and become a "short mark"; Second, the moving average temperature of five consecutive groups is lower than 22℃. A set of moving average temperatures refers to the average temperature of the day plus the average temperature of the previous four days divided by 5 to get the moving average temperature of five days, which is a "sliding scale". Autumn divided by temperature means cool weather.
