The beginning of spring marks the end of the winter season, when everything was hidden, and the beginning of the spring season, when the winds are gentle and the sun is warm, and everything grows. In nature, the most significant feature of spring is that everything begins to show signs of recovery. When the spring, in China's Tropic of Cancer (yellow and red angle) and south of the area, can clearly feel the breath of early spring. Because of the vastness of our country, the north-south span, the natural rhythms of different places, "spring" for many areas is just a prelude to spring, everything has not yet recovered, is still in the winter of all things closed.

The spring is the first of the 24 solar terms. It is the first of the twenty-four solar terms, which means "beginning", and "spring", which means warmth and growth. The twenty-four solar terms were originally developed based on the "rotation of the Big Dipper", when the handle of the Big Dipper points to the c position, it is the beginning of spring.
