What does it mean that spring thunder scares all insects?

Spring thunder will ring before and after the sting, insects in winter will wake up in the spring thunder, and hibernating animals will wake up, representing the arrival of mid-spring season.

Sting is the third solar term in spring. Except for the snow and ice in the north, the rest of the region began to have the breath of spring. "Spring thunder rings and everything grows." At this time, the sound of spring thunder sounded everywhere, awakened hibernating snakes, insects, rats, ants, animals and birds, and sensed that people were going to prepare for spring ploughing.

In ancient times, the fright was divided into three stages: "When the peach blossoms first opened; Second, wait for the oriole to sing; Three waiting eagles turned into pigeons. " Peach blossoms bloom first, and orioles sing again. This is the change of the weather, but the time of ringing spring thunder varies from place to place. There is a lot of rain in the south, and you can already hear the spring thunder with the rain when you are awake, but North China is too dry to hear it until Tomb-Sweeping Day. This should be due to the large span between north and south in China, and the ground temperature is different from the rising cold air activity.

In folk proverbs, the fright is "cold fright, warm vernal equinox", "fright blows the south wind, the seedlings are late" and so on, which proves that it is cold at first and the temperature is unstable. However, because everyone should be prepared during the busy farming season, no matter how cold the weather is, it can't interfere with everyone's enthusiasm for farming in time, so there is a saying that it is just like steaming steamed bread and leaving gas. It can be seen that fright is important for farming.
