Introduction:

Twenty-four solar terms (Twenty-four solar terms) is a knowledge system and social practice formed by China people by observing the movement of the sun for a year and understanding the changing laws of the four seasons, climate and phenology in a year. It is the product of ancient farming civilization and has been guiding the traditional agricultural production and daily life in China for thousands of years.

Twenty-four solar terms are China people's world outlook, which reveals and refines this orderly ecological change law in a year. As the main political, economic, cultural and agricultural activity centers in China are mostly concentrated in the Central Plains of the Yellow River Basin in history, the 24 solar terms were established based on this area.

As early as the Spring and Autumn Period, the ancient sages of China set four solar terms: midsummer, midsummer, midsummer and winter solstice, and constantly improved and perfected them. By the Qin and Han Dynasties, the 24 solar terms had been completely established and became a supplementary calendar used to guide farming in ancient China. In the field of international meteorology, the 24 solar terms are known as "the fifth invention of China".
