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".
