The road of rain and solar terms is smooth.

The east wind thaws, the rain falls, everything sprouts, and spring is ushered in, which comes from the "rain" of the 24 solar terms. Rain is the second of the 24 solar terms. Every year around the 15th day of the first month (February 18-20 in Gregorian calendar), 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. Generally, the rainy and rainy solar term begins on February 18 or 19 of Gregorian calendar and ends on March 4 or 5. Rain, like Grain Rain, light snow and heavy snow, is a solar term reflecting precipitation.

With the arrival of the rain solar term, the precipitation in the south gradually increased, and the snowfall in the north gradually turned into rainfall; It means that the weather will gradually get warmer, and then people's clothes will gradually become thinner.

Rain solar terms include returning to one's mother's house, pulling Michelle Platini, and collecting longevity. It is a popular custom in western Sichuan to go back to her mother's house in rainy days. On this day, the married daughter will visit her parents with canned meat, chairs and other gifts to thank them for their parenting.

Rain festival pulls michel platini, which means "rain and dew moisten and grow easily". On this day, parents should get michel platini to prepare the dining table for their children, so that they can grow up healthily and safely.
