In ancient times, rainwater was divided into three stages: "One stage was that Rex sacrificed fish; Second, wait for Hongyan to come; Third-class grass sprouted. " In this solar term, otters start fishing and put the fish on the shore like a sacrifice before eating.

What is rain?

The ancient characters of rain and rain have horizontal sky symbols above them and dome symbols below them, symbolizing the rise of clouds and gas; Explain "no clouds and no rain" The wind blew away and it rained, so there were four rows of raindrops under the dome, each with three points.

Weather changes of rain solar terms

When early spring comes, the temperature rises, but this increase is a gradual process. The temperature will rise and fall, and the weather will be hot and cold.
