Praying for rain was recorded as early as the Western Han Dynasty in China. It is a folk activity, a true portrayal of farmers' life in China, and reflects people's expectations for a better tomorrow and a better life in a harsh natural living environment. It really wants to turn the idea that there is no heaven on earth into an ideal reality.
It doesn't rain in the north of China all year round. In order to survive and live, people burn incense and pray for angels to help people.
