Is the origin of need related to water?

Rain is the second of the 24 solar terms. Because it is the time when the snow and ice melt and the precipitation increases, this solar term is called "rain" in order to reflect the precipitation.

Rainy and solar terms, warmer weather, less snowfall and more rainfall. Plants will use this rain to absorb water and start to sprout and grow. Crops are no exception. Wheat seedlings, rape, etc. Everything began to rise. If the water content is moderate during this period, the growth momentum of crops will be particularly good, and this year's harvest will have a good start.

This time is also the time to graft fruit trees and plant trees, because everything has just begun to sprout and there is a lot of precipitation. However, although there are many spring rains, they are all "continuous spring rains", which are not as big and urgent as summer rainstorms, and are very suitable for watering newly grafted and planted trees. There is a saying in the folk proverb that "spring rain is as expensive as oil", which shows how precious rain is when it rains.
