Stay in a daze, and the vernal equinox will not go up the mountain.

This is a cultural custom between man and nature. The revival of everything in the Spring Festival is an important growth period of the year. Some ethnic minorities are forbidden to cut mountains and protect water and soil in spring.

Scared sting, called Tanabata in ancient times, is the third of the 24 solar terms, marking the beginning of the mid-spring season. In the past, animals hid in the soil in winter without drinking or eating, which was called "sting"; On the day of "Sting Festival", the spring thunder in the sky awakens the secluded animals, which is called "shock". Therefore, insects wake up when they are startled. As the weather gets warmer, there are gradually spring thunder, and most parts of China enter the spring ploughing season.

The vernal equinox is the midpoint of 90 days in spring. One of the 24 solar terms, the sun is at 0. On the vernal equinox, the sun shines directly at the equator of the earth, and the seasons in the northern and southern hemispheres are opposite.
