The twenty four solar terms are the knowledge system formed by ancient people's observing the movement of celestial bodies and recognizing the changing laws of seasons, climate and phenology in the middle of a year.
Monsoon climate is the main feature of China's climate, which is a mixture of continental climate and oceanic climate. In winter, affected by the dry and cold airflow from inland, the weather is cold and dry with little rain;
In summer, it is affected by the warm and humid air flow from the ocean. The high temperature of monsoon climate is basically consistent with the rainy period, and the rainfall and heat are synchronous. Although it is hot, humid and rainy, it is hard to live with,
