Dashu is the twelfth of the twenty-four solar terms, a time system that embodies the traditional knowledge and social practices by which the Chinese obtain their perception of the regularity of the seasons and other local natural phenomena occurring throughout the year. Shu means scorching heat, and Dashu refers to extreme heat.
Dashu is the sunniest and hottest solar period of the year, with the most thunderstorms and rainfall. The monsoon climate is the main characteristic of China's climate. In summer, influenced by the warm and humid air from the sea, many places in China are very hot, humid and rainy. Although it is unavoidable to suffer from heat and humidity, it is conducive to the growth of crops, which grow fastest during this period.
Since ancient times, people have had the custom of drinking herbal tea (fucha), burning incense and drying ginger during Dashu. Since it is the hottest and most humid season of the year, the focus of healthcare is on "preventing heat stroke" and "eliminating humidity."
