What are the following phenomena of rain solar terms?

Spring is naturally inseparable from the moisture of boiling water. Before and after the rainy season, plants germinate. "When it rains, everything is beautiful." Spring rain moistens things silently, so that dead trees meet spring and seeds germinate. The natural phenology of rain solar terms in China is quite different between north and south. There is no smell of spring in the north, but most parts of the south are already the scene of early spring.

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".

Introduction of solar terms:

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.

According to Jingchu Chunqiu, the letter of Yuhua is: first-class cauliflower, second-class apricot flower and third-class plum flower. Bloom's third wait was on time. Cauliflower, or rape flower, is widely cultivated in China. Every year, from 65438+ 10 to August, with the movement of direct sunlight, rape flowers bloom from south to north, presenting a golden magnificent scene.
