The vernal equinox is one of the twenty-four solar terms and the fourth solar term in spring. Celebrate every year on March 19~22 in Gregorian calendar. At the vernal equinox, the direct point of the sun is on the equator, and then the direct point of the sun continues to move northward, so the vernal equinox is also called the ascending equinox. In ancient times, it was also called Japan-China, day and night, and mid-spring moon.

The vernal equinox is an important solar term, which is of great significance in astronomy: the northern and southern hemispheres are equally divided day and night. In climate, it also has obvious characteristics. Since then, the direct position of the sun has continued to move from the equator to the northern hemisphere. The day in the northern hemisphere began to be longer than the night, and the day in the southern hemisphere began to be shorter than the night. During the spring equinox, China has entered a bright spring except the Qinghai-Tibet Plateau, Northeast China, Northwest China and North China. At this time, the climate is mild, the rain is abundant and the sun is shining, and the wintering crops in most parts of China enter the spring growth stage.
