Questions about the 24 solar terms! Come on, come on! ! !

As early as the Spring and Autumn Period and the Warring States Period, people in China had the concepts of Solstice in the South and Solstice in the North. Subsequently, people divided the year into 24 equal parts according to the relationship between the running position of the sun and the moon at the beginning and middle of the month and the natural utilization such as weather, animal and plant growth. And give each equal part a proper noun, that is, twenty-four solar terms. By the end of the Warring States Period, solar terms had eight names: beginning of spring, Equinox, Long Summer, Summer Solstice, beginning of autumn, Equinox, beginning of winter and Winter Solstice. These eight solar terms are the most important of the 24 solar terms. These eight solar terms mark the change of seasons and clearly divide the four seasons of the year. Later, when the book Huai Nan Zi was published, the names of the 24 solar terms were exactly the same as those of the modern ones.

Of course it is valuable. Twenty-four solar terms are the original cultural heritage of the working people in China. They can reflect the changes of seasons, guide agricultural activities, and affect the food, clothing, housing and transportation of thousands of families. Since 2000, the main political activity center in China has been concentrated in the Yellow River Basin, and the 24 solar terms have been established on the basis of the climate and phenology in this area.
