The origin of the twenty-four solar terms

Historically, the main centers of political, economic, cultural and agricultural activities in China were mostly concentrated in the Central Plains of the Yellow River Basin, and the 24 solar terms were established on the basis of climate and phenology in this area. As early as the Eastern Zhou Dynasty, the Spring and Autumn Period and the Warring States Period, the working people in China had the idea that "the sun will arrive in the south" and "the sun will arrive in the north". Subsequently, people divided the year into 24 equal parts according to the natural phenomena such as the running position of the sun and the moon at the beginning and middle of the month, the weather and the growth of animals and plants.

Give each equal part a proper name, that is, 24 solar terms. By the end of the Warring States period, there were eight solar terms, such as beginning of spring, Spring Equinox, Long Summer, Summer Solstice, beginning of autumn, Spring Equinox, beginning of winter and Winter Solstice, which were the most important of the 24 solar terms. Mark the seasonal changes and clearly divide the four seasons of the year. By the Qin and Han Dynasties, the 24 solar terms had been completely established.
