What does the rain solar term mean? When does it rain?

Rain is the second of the 24 solar terms, and the time is one of February 18-20 in the solar calendar every year, and the sun reaches 330. The arrival of the rain solar term marks the beginning of rainfall, which gradually increases. Entering the rain solar term, the cold in the north is not exhausted, and the temperature changes greatly; Most places in the south are full of spring, with a scene of early spring.

In ancient China, rainwater was divided into three stages: "One stage was that Rex sacrificed fish; Second, wait for Hongyan to come; Third-class grass sprouted. " After the rain, the otter began to fish, and when he ate the fish, he put it on the shore, as if he had been sacrificed first and then eaten. Five days later, the geese began to fly back to the north from the south; In five days, in the "moist and silent" spring rain, the spirit of the sun rises everywhere in the vegetation and begins to sprout. Since then, the earth has gradually begun to show a thriving scene. On rainy days, there are also many folk activities, such as "pulling bags" and "wandering off".
