Why is awn planted all over the world?

The ancient farming society was based on agriculture. Twenty-four solar terms is a calendar established in ancient China, which is specially used to guide agricultural cultivation. People divide a year into 24 equal parts according to the natural phenomena such as the position of the sun and the moon, the weather and the growth of animals and plants at the beginning of the month and in the middle of the month.
