What is the influence of the 24 solar terms on ancient agriculture?

Twenty-four solar terms are a supplementary calendar for guiding farming in ancient China, which was formed in the Spring and Autumn Period and the Warring States Period. Because the lunar calendar in China is a "Yin-Yang calendar", which is based on the movement of the sun and the moon, and cannot fully reflect the solar cycle. However, China is an agricultural society, and agriculture needs a strict understanding of the movement of the sun, so farming is based entirely on the sun, so "twenty-four solar terms" reflecting the solar cycle alone are added to the calendar to determine the leap.

24 solar terms's formula: Spring rains shake the valley, summer is full of mountains and rivers, and summer is hot.

There are dewdrops in autumn, first frost in cold, light snow in winter and cold in winter.

Two festivals in a month remain the same, with a difference of one or two days at most.

The first half of the year is 62 1, and the second half is 823.
