Season refers to the twenty-four seasons and climate, is a kind of supplemental calendar used to guide the agricultural affairs established in ancient China, is the accumulated results of the long-term experience of the working people of the Chinese nation and the crystallization of wisdom. Since ancient China was an agricultural society, agriculture required strict knowledge of the operation of the sun, and farming was conducted entirely according to the sun, so the "twenty-four seasons" reflecting the sun's operation cycle alone were added to the calendar, and used as a criterion for determining the intercalary month. The orthodox Chinese 24 solar terms are based on Henan. The Chinese lunar calendar is a yin-yang calendar, which is based on the movement of the sun and the moon, so the addition of the 24 solar terms better reflects the sun's cycle.
