What does spring thunder mean?

Playing spring thunder represents the recovery of the earth and the warming of the weather. It means that spring has arrived, which means that the qi of Yin and Yang has begun to change, everything germinates with the increase of temperature, and the earth presents the image of spring and beauty. Spring thunder awakens all hibernating snakes, insects, rats and ants, and forages everywhere. In ancient times, people would hold wormwood in their hands and drive away snakes, insects, mosquitoes, rats and musty smells with fragrance.

Thunder:

Thunder is a natural phenomenon. When it rains, some clouds in the sky are positive and some are negative. When two kinds of clouds meet, they will emit lightning and a lot of heat, which will make the surrounding air heat and expand. Instantly heated and expanded air will push the surrounding air and produce strong explosion vibration. This is thunder.

Lightning is a discharge phenomenon in thunderstorm clouds. Thunderstorm clouds generally have two conditions, sufficient water vapor and strong convection. In winter, because the air is cold and dry, the solar radiation is weak, and convection is not easy to form in the air, so lightning is rare. But sometimes when the temperature is high in winter, it will form thunderstorm clouds, leading to lightning and rain and snow.
