What are the three periods of rain?

The three stages of rain are waiting for Rex to sacrifice fish, waiting for Hongyan to come, and waiting for vegetation to sprout. The otter began to fish and put the fish on the shore like a sacrifice before eating. Five days later, the geese began to fly back to the north from the south. Five days later, in the quiet spring rain, there was sunshine everywhere and it began to sprout. Since then, the earth has gradually begun to show a thriving scene.

Brief introduction of rainwater

Rain is the second of the 24 solar terms. When the sun reaches the longitude of 330, it will cross the Gregorian calendar on February 18-20 every year. Rain solar term means that it begins to rain, and the rainfall level is mainly light rain or Mao Mao rain. As the saying goes, spring rain is as expensive as oil, and suitable precipitation is very important for the growth of crops. It is the reflection of farming culture on festivals.

Entering the rain solar term, there is no breath of spring in the northern part of China, but most parts of the south are full of spring, with a scene of early spring. The rain solar term generally starts from February 18 to 20 and ends on March 4 or 5. In the rainy season, the direct point of the sun gradually approaches the equator from the southern hemisphere.

At this time, in the northern hemisphere, the sunshine hours and intensity are increasing, and the temperature is rising rapidly. Warm and humid air from the ocean becomes active and gradually pushes northward to meet with cold air, forming rainfall. The rainy season is changeable, which is one of the seasons with the most cold wave processes in the whole year, with cold and hot, warm and cold at first.
