Pang, a poet in the Song Dynasty, recorded in Wenchang Miscellanies: "There are seventy-six days of vacation, seven days on January 21, cold food and winter solstice, and Tianqing Festival and Shangyuan Festival are the same." There are 76 legal holidays in a year, among which 7 are Spring Festival, Cold Food Festival (Tomb-Sweeping Day), Winter Solstice, Emperor's Birthday and Lantern Festival.
Lantern Festival is the "Lantern Festival", which not only enjoys lanterns, but also makes lanterns. Shangyuan lights up for three days and turns off the lights on the 18th night of the first month. Lantern Festival is the biggest event of the year in Beijing. In order to prepare for the three-day Lantern Festival, Tokyo in the Northern Song Dynasty began to prepare before the Spring Festival.
