In ancient times, from Xiaohan to Guyu, there were eight solar terms in four months. During this period, a kind of wind was named after a flower that was blooming at that time every five days. There were a total of twenty-four winds, called the twenty-four flower trade winds. Willow flowers are the third queen of the Qingming Festival, and neem flowers are the third queen of the Grain Rain.
Purpose: Carry forward the traditional Chinese culture of the twenty-four solar terms
