Solar terms provide a prerequisite for the emergence of festivals. After Tomb-Sweeping Day, the temperature became warmer, the rain increased, and the earth showed a beautiful scene of spring. At this time, everything, whether it is the vegetation in nature or the human body in natural places, has changed the filth in winter, ushered in the breath of spring and realized the transformation from yin to yang.

Solar terms are symbols of phenological changes and seasonal order in China, while festivals contain certain customs and activities, which have certain commemorative significance.
