Spring, the first of the four seasons, refers to the period from beginning of spring to long summer, including solar terms such as beginning of spring, rain, fright, vernal equinox, Qingming and Grain Rain. Spring represents warmth and growth. In spring, the qi of yin and yang begins to change, and everything germinates with the rise of yang. Spring is one of the four seasons. As far as solar terms are concerned, spring begins in early spring and ends in long summer. Twenty-four solar terms are the product of ancient farming civilization in China, and the division of four seasons begins with "four stands". In the historical development, cultural exchange and communication, four solar terms (vernal equinox, autumnal equinox, summer solstice, winter solstice) reflecting the return movement of the direct point of the sun were all over the pre-Qin period. The division of the four seasons in the west is based on the dichotomy, that is, spring is divided into beginning of spring.
