What are the characteristics of rain solar terms?

The origin of rain solar terms is as follows:

Rain is the second solar term in a year. "Between two dimensions, 9 1 degree and 16 degree" is divided into six solar terms on average, and each solar term accounts for 15 days. So fifteen days after winter, the solstice will be slightly cold, another fifteen days will be severe cold, and another fifteen days will be beginning of spring. Fifteen days after beginning of spring, it began to rain. This is how the date of the rain solar term is calculated.

Wu Cheng's book "Twenty-four Solar Terms" in the Yuan Dynasty said: "The first month is aquatic in the sky, and spring is wood. However, people who grow trees must have water, so it rained successfully in beginning of spring. If the east wind melts, it will disperse into rain. " Rain means that the spring breeze gradually blows all over the earth, the ice and snow melt, and even the air in the north begins to become moist, showing a thriving scene everywhere.

Rainwater introduction:

Rain solar term means the beginning of rainfall, which is mostly light rain or Mao Mao rain. Proper precipitation is very important for the growth of crops, and 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 places in the south are full of spring and a scene of early spring.

Spring is inseparable from rain, which moistens things silently, so that dead trees can welcome spring and seeds can germinate. In ancient times, rainwater was divided into three stages: "One stage was that Rex sacrificed fish; Second, wait for Hongyan to come; Third-class grass sprouted. " Rain in the "July 9" period, the river broke the ice and the geese returned to the north. Folk customs related to rain mainly include "mending the sky and wearing it", "protecting the sky" and "bumping into worship and sending it away".
