Rain solar term means 50 words.

The arrival of rain represents the arrival of spring. At this time, the ice and snow are slowly melting and the weather is getting warmer and warmer. It was the time when everything was revived, and even the cold northern air began to get wet. At this time, most areas have begun to show a thriving scene. The taste of spring is getting heavier and heavier.

In terms of weather, the temperature will rise obviously after the rain. The temperature in most parts of China can basically reach above 0 degrees, and the general temperature in South China can reach above 10. At this time, rape and winter wheat generally turn green, and the demand for water is still relatively high during this period.

As the saying goes, "Spring rain is as expensive as oil", and suitable precipitation is very important for the growth of crops. At this time, the precipitation in North China, Northwest China and Huanghuai areas is generally less. If there is little rain in early spring, timely irrigation after rain is beneficial to crop growth.

There will be some precipitation in many places before and after it rains, and people will judge the weather according to the temperature of the rainfall. For example, the proverb says that when it rains, it's gloomy in Grain Rain, "cold rain, warm shock", "warm rain, cold shock", or "when it rains from the east wind, it rains in dog days".
