The meaning of panic.

The moral of fear is that the weather gets warmer and the spring thunder begins to sound. It means that during the dormant season, the weather begins to pick up. Spring thunder came, and it began to thunder in many areas. Then it began to rain, and the increase of rain also kept farmers busy farming. "Sting" means "hiding". In winter, insects hide in the soil. "Surprise" means "wake up". Spring thunder in the sky woke up the bugs. The so-called "spring thunder" means that when the spring thunder begins to sound, it wakes up the stinging insects that are dormant in the ground for the winter. In some ancient places, people smoked the four corners of their houses with incense and wormwood to drive away "snakes, insects, mosquitoes and rats" and musty smell. Over time, it gradually evolved into the custom of shocking and beating villains to drive away bad luck. In addition, there are customs such as "covering the drum skin", "eating pears" and "offering sacrifices to white tigers to resolve right and wrong".

The symbolic feature of the shocking solar terms is that spring thunder suddenly moves and everything is full of vitality. Judging from the natural phenological process in various parts of China, due to the large span between north and south, the time when spring thunder begins to ring is different in the morning and evening. "Thunder begins with your surprise" just coincides with the natural rhythm in some parts of southern China.

Spine reflects the state of germination and growth of natural organisms affected by rhythm changes. Speaking of earthquakes, the sun's spirit rises, the temperature warms up, the spring thunder suddenly moves, the rain increases, and everything is full of vitality. Farming production is closely related to the rhythm of nature, and the solar term of fright is of great significance in farming, which is the reflection of ancient farming culture on natural festivals.
