When will it rain?

It rains on the 15th day of the first month of every year (February 18-20 in Gregorian calendar).

Rain is one of the 24 solar terms. On this day, a daughter went back to her mother's house and brought her a piece of red silk and a pot of stew. Because around the fifteenth day of the first month, the temperature rises, the snow melts, the water vapor increases, and the precipitation increases, it is called "rain".

In the twenty-four solar terms, I wrote: "In the first month, water is generated every day. Spring belongs to wood, but there must be water for those who grow wood, so there is rain in beginning of spring. If the east wind melts, it will disperse into rain. " In other words, in this solar term, everything begins to wake up with the rain, and spring warms the earth and everything germinates. This is the time when rape and wheat seedlings begin to grow. If there is not enough rain, it is necessary to pump water in time for irrigation. If there is too much rain, it is necessary to clean ditches, drain water from fields and reduce root rot.

In the rainy season, peach blossoms and cherry blossoms will bloom one after another, which is a good time to enjoy the scenery in spring. It is also the time to graft fruit trees and plant trees. "Spring rain is as expensive as oil" In the spring rain, plants grow rapidly, and you can see the changes of surrounding plants with the naked eye every day.

In this season, because it has just begun to pick up, the temperature changes are unstable and the cold air activities are frequent, so we should do a good job of "spring cover" and don't take off our winter clothes immediately to avoid catching a cold. Pay attention to nourishing the spleen and stomach, expelling wind and removing dampness when eating. The climate is still cold and can be supplemented appropriately. Eating some honey, yam and jujube is a good choice.
