Solar terms refer to the twenty-four seasons and climate, which is a supplementary calendar made in ancient China to guide farming, and is the crystallization of the long-term experience and wisdom of the working people of the Han nationality.

Because China was an agricultural society in ancient times, agriculture needed to know the operation of the sun strictly, and farming was carried out entirely according to the sun, so "twenty-four solar terms" which reflected the operation cycle of the sun alone were added to the calendar as the criteria for determining leap months.

China's orthodox 24 solar terms are based on Henan. The lunar calendar in China is a combination of yin and yang, which is based on the sun and the moon's movement, so adding 24 solar terms can better reflect the cycle of the sun's movement.

24 solar terms are: beginning of spring, Rainwater, Jingzhe, Vernal Equinox, Qingming, Grain Rain, long summer, Xiaoman, Mangzhong, Summer Solstice, Xiaoshu, Dashu, beginning of autumn, Chushu, Bailu, Autumnal Equinox, Cold Dew, first frost, beginning of winter, Xiaoxue, Heavy Snow, Winter Solstice, Slight Cold and Severe Cold
