The formation of Lantern Festival custom has a long process, and attention has been paid to the fifteenth day of the first month since the Western Han Dynasty. On the night of the first month, Emperor Wu of the Han Dynasty offered sacrifices to "Taiyi" in Ganquan Palace, which was regarded by later generations as the first sacrifice to the gods on the fifteenth day of the first month.

However, the Lantern Festival on the fifteenth day of the first month is indeed a folk festival after the Han and Wei Dynasties. The custom of burning lanterns on the fifteenth day of the first month is related to the eastward spread of Buddhism. During the Tang Dynasty, Buddhism flourished.

Officials and ordinary people generally "burn lanterns to worship Buddha" on the fifteenth day of the first month, so Buddha lanterns are spread all over the people. Since the Tang Dynasty, the Lantern Festival has become a legal thing and has gradually become a folk custom. ?
