What is the significance of the 24 solar terms?

The systematic record of the twenty-four solar terms began with Zhoupian and Huainanzi. It accurately reflects the relationship between the sun and the earth formed by the revolution of the earth, which is very consistent with the cold, warm, dry and wet climate changes in the Yellow River basin in a year, and it is more convenient to grasp the agricultural time according to the full moon and short month. It is a great creation of China's agricultural timing method, and it still plays a guiding role in agricultural production.
