Which season is the node where the yang gradually closes and the yin gradually grows, and the yang gradually becomes cloudy?

Beginning of autumn is the node where Yang gradually closes and Yin gradually grows, and Yang gradually turns into Yin.

Beginning of autumn is the thirteenth of the twenty-four solar terms, and it is the beginning of autumn. The bucket refers to the southwest, and the sun reaches the longitude of 135, and it is celebrated on August 7 or 8 of the Gregorian calendar every year. "Reason" means the beginning; "Autumn" means that the grain is ripe.

The change of the whole nature is a step-by-step process, and beginning of autumn is a turning point in which the Yang gradually closes, the Yin gradually grows, and the Yang gradually gets cloudy. In nature, everything begins to mature from luxuriance.

Beginning of autumn is the third hot solar term among the 24 solar terms, second only to Daxia and Xiaoxia. According to the order of solar terms, beginning of autumn is followed by summer, and autumn is the second solar term "Summer comes" (the last summer). Twenty-four solar terms include "three summers" (little summer, big summer and midsummer), and there is a "beginning of autumn" solar term in the middle of the "three summers", followed by summer (last summer) after beginning of autumn.

"Three Summers" and "Dog Days" both represent hot and humid weather, and "Dog Days" involve four solar terms: Little Summer, Big Summer, beginning of autumn and Early Summer. Among the 24 solar terms, the days in summer are longer.

Seasonal division

1, solar terms method: The traditional method of dividing the four seasons takes "Li Si" in the 24 solar terms as the starting point of the four seasons, so beginning of autumn is the starting point of autumn. Bucket refers to beginning of autumn in southwest China. When the sun reaches longitude 135, it starts in the beginning of autumn and ends before beginning of winter in autumn. Beginning of autumn means that the sun be the spirit gradually closes, the yin be the spirit gradually grows, everything begins to move from luxuriant to mature, and the harvest season has arrived.

2. Temperature method: At present, the four seasons are often divided according to the temperature change, and the "average weather temperature" of modern scholar Zhang Baokun is used to divide them. According to the weather average temperature method, the average daily temperature for five consecutive days is between 10℃ and 22℃, which is regarded as autumn. Autumn divided by temperature means cool weather.
