Why is it called rain?

It is the reflection of precipitation phenomenon and ancient farming culture on festivals. Similar solar terms include Grain Rain, Xiaoman, light snow and heavy snow. Rainwater solar term marks the beginning of rainfall, and suitable precipitation is very important for the growth of crops. Entering the rainy solar term, the northern part of China is still cloudy and cold, and it is still snowing in some places, and there is no breath of spring; Most places in the south are full of spring, with a scene of early spring.

Rain is the second of the 24 solar terms. Every February 19 or so, when the longitude of the sun reaches 330 degrees, it is the rain of 24 solar terms. At this time, the temperature rises, the snow melts and the precipitation increases, hence the name rain. The rain solar term generally starts from February 18 or 19 and ends on March 4 or 5. Rain, like Grain Rain, light snow and heavy snow, is a solar term reflecting precipitation.

It rained three times.

There are three periods of rain, one is when water otters sacrifice fish, the other is when geese come, and the third is when plants sprout. It is said that the solar term of rain has come, the ice on the water surface has melted, and otters have started fishing. Otters like to kill the fish and put them on the shore in turn, just like offering sacrifices, so there is a saying that "Rex sacrifices fish".

Five days after the rain, the geese began to fly back to the north from the south. In five days, plants will begin to sprout as the spirit of the sun rises underground. Since then, the earth has gradually begun to show a thriving scene.
