2. The vernal equinox is the fourth of the 24 solar terms, and it is an important solar term, which is of great significance in astronomy: the northern and southern hemispheres are divided into equal parts 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.

For example, in spring, beginning of spring is the starting point, beginning of spring is the midpoint, and the long summer is the end point. The division of the four seasons in the west takes "dichotomy and dichotomy" as the starting point of the four seasons, such as spring as the starting point and summer solstice as the end point. Western countries are located at higher latitudes, far away from the intersection of Huangchi and Huangchi, and take "equal division to" as the starting point of the four seasons, which actually reflects the local climate better than "Li Si". The four seasons divided by "dichotomy" and "dichotomy" in the west are one and a half months later than those divided by "Li Si" in China.
