What do you mean by "the east wind thaws the stinging insects and shakes the fish into ice"? From where?

"The east wind dispels the sting insect, and the fish turns into ice" comes from the Book of Rites and the Moon Order. It means: at this time, the east wind melts into cold, hibernating animals begin to move, and fish swim upstream to the ice.

Book of Rites and Moon Order: one of the Confucian classics, and Book of Rites and Moon Order No.6 is its full name. It can be divided into Meng Chunyue, Zhong Chunyue, Ji Chunyue, Midsummer Moon, Midsummer Moon, Mid-year Festival, Meng, Mid-autumn Moon, Mid-winter Moon and Mid-winter Moon * * 6544.

It depicts the world as a multi-level structure. The sun is the highest and decisive. Eclipses form four seasons, and each hour is divided into three months. Every season has its own climate characteristics, and every month has its own symptoms. Corresponding to the four seasons, there is a class of emperor gods every hour, corresponding to the changes of time, month and god, and each month has its own ritual system.
