The arrival time is on February 3-5 of the Gregorian calendar every year (around the first day of the first lunar month), when the sun reaches 3 15. Beginning of spring is one of the important traditional festivals of the Han nationality. "Li" means "start". Since the Qin Dynasty, China has always regarded beginning of spring as the beginning of spring.

The period from the beginning of the Spring Festival to the long summer is called spring.
