What is the solar term of the vernal equinox and what is its special significance?

The vernal equinox is the midpoint of 90 days in spring. One of the 24 solar terms, around March 20 of the Gregorian calendar every year, when the sun is located at 0 (vernal equinox) of the yellow meridian. 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. The northern hemisphere is the vernal equinox and the southern hemisphere is the autumnal equinox.

After the vernal equinox, the overwintering crops in most parts of southern China entered the spring growth stage. The temperature in most parts of the south continues to rise, but generally it doesn't rain as fast as the vernal equinox. In late March, the average temperature in northern South China is mostly 13℃ to 15℃, and in southern South China it is mostly 15℃ to 16℃. Most of the plateau has been melted by snow, and the ten-day average temperature is about 5℃ to 10℃.

As the saying goes, "The spring equinox begins with wheat, and the fat and water should follow". A spring rain was warm. After the spring rain, I was busy plowing. The busy farming season in spring is about to begin, and spring management, spring ploughing and spring planting are about to enter a busy stage. After the vernal equinox, overwintering crops enter the growth period, so field management should be strengthened.
