Beginning of spring is the first of the 24 solar terms in the lunar calendar. Beginning of spring is divided from astronomy, that is, when the sun reaches longitude 3 15. Beginning of spring is one of the important traditional festivals in China. "Li" means "start". Since the Qin Dynasty, China has always regarded beginning of spring as the beginning of the Meng Chun season.

Beginning of spring, as a festival, existed as early as the Spring and Autumn Period. At that time, there were eight festivals in a year, namely beginning of spring, Changxia, beginning of autumn, beginning of winter, Vernal Equinox, Summer Solstice and Winter Solstice. Only the Book of Rites and Annals of Huainanzi by Liu An in the Western Han Dynasty recorded 24 solar terms.
