During the period of Emperor Wu of the Han Dynasty, the sacrificial activities of "Taiyi God" were scheduled for the 15th day of the first month (Taiyi: the God in charge of everything in the universe). When Sima Qian created the taichu calendar Law, he had already identified the Lantern Festival as a major festival.
Traditional customs include going out to enjoy the moon, lighting lanterns and setting off flames, liking solve riddles on the lanterns, eating Yuanxiao and pulling rabbit lanterns. In addition, in many places, traditional folk performances, such as playing dragon lanterns, playing lions, walking on stilts, boating, yangko dancing and playing Taiping drums, have all joined the Lantern Festival. In June 2008, the Lantern Festival was selected as the second batch of national intangible cultural heritage.
Eating glutinous rice balls on the Lantern Festival has the health-preserving effects of keeping out the cold, strengthening the spleen and benefiting the lungs. The coldest winter is March 9. Although it has passed now, the weather is warm and cold at first. The ancients made zongzi on the fifteenth day of the first lunar month. Zongzi is not only sticky glutinous rice, but also easy to cook and won't come loose, because glutinous rice has the characteristics of keeping out the cold.
