Governors and countries have 24 solar terms. Why are there 30 solar terms in Qi?

Because the thirty solar terms of Qi are in October, that is to say, there are only ten months in a year, with thirty-six days as a month and seventy-two days as a quarter, which is exactly 360 days. The solar terms adopted by Qi are different from those adopted by other countries, mainly from the book Guanzi. Qi adopts the system of four seasons in a year.

These 30 solar terms are as follows: the eight solar terms in spring are: Tiki method, kitten, last quarter moon, one go, Qingming, Chumao, Zhongmao and Xiamao; The seven stages of summer are Xiaoying, Exhausted, Ying Zhong, Moderately Exhausted, Mild Summer Arrival, Heatstroke and Late Summer. The eight stages of autumn are wind arrival period, small base period, white dew period, recovery period, pre-holiday, early base period, middle base period and lower base period in turn; The seven stages of winter are the beginning of cold, slight cold, moderate cold, moderate cold, severe cold, the yin of severe cold and the end of severe cold.

So why make such a distinction? Is there any legend? It turns out that this has a lot to do with the geographical location and climate of Qi, and the temperature in Shaanxi where Zhou people are located is just right, and the precipitation is OK. Winter is not particularly cold, and the four seasons are quite distinct.

Qi people live in Shandong, because they are close to the sea, so the spring and autumn are shorter and the winter and summer are longer. Obviously, this climate is quite special. It is said that Jiang Ziya was seen when it was closed, so each solar term was divided into twelve days, because the finer the division, the more conducive to farming and farmers' work.

There is also a saying that the 30 solar terms of Qi are related to the theory of Yin-Yang and Five Elements. The theory of five elements also comes from qi. This man named Zou Yan was deeply influenced by the living habits and culture of Qi. He studied for many years before writing the theory of five elements, and one of the five virtues also used solar terms from beginning to end, which was specially used for the replacement of dynasties, so this statement has also been circulated to this day.
