What festival is it when it rains in Tomb-Sweeping Day?

It was Tomb-Sweeping Day,

Tomb-Sweeping Day: Tomb-Sweeping Day is one of the 24 solar terms in the lunar calendar. At the turn of mid-spring and late spring, it is usually 106 days after the winter solstice. The traditional Tomb-Sweeping Day of the Han nationality in China began in the Zhou Dynasty and has a history of more than 2,500 years.

Qingming is generally around April 5 of the Gregorian calendar every year. Because the 24 solar terms objectively reflect the changes of temperature, rainfall and phenology throughout the year, ancient working people used them to arrange agricultural activities.

However, as a festival, Tomb-Sweeping Day is different from pure solar terms. Tomb-Sweeping Day is an important traditional festival in China, and solar terms are the symbol of phenological changes and seasonal order in China, while festivals contain certain customs and activities and certain commemorative significance. Tomb-Sweeping Day is also called an outing festival. According to the Gregorian calendar, April 4-6 every year is a season of bright spring and lush vegetation, and it is also a good time for people to have a spring outing. Therefore, the ancients had the custom of going for an outing in Qingming and carrying out a series of sports activities.

Later, Tomb-Sweeping Day gradually evolved into a traditional festival in China, and it is also the most important festival to worship ancestors and sweep graves.
