Beginning of spring time is determined by astronomy, that is, when the sun reaches 3 15 degrees, it is beginning of spring. 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.

Twenty-four solar terms were originally formulated on the basis of "variable stars". When the bucket handle of the Big Dipper points to the shade, it is beginning of spring. At present, solar terms are determined according to the longitude of the sun. When the sun reaches longitude 3 15, it will be the beginning of spring, and the festival will be held from February 3 to 5 of the Gregorian calendar every year.
