The Lantern Festival is a traditional festival in China. The formation of Lantern Festival customs has a long process. According to general information and folklore, the fifteenth day of the first lunar month has been taken seriously in the Western Han Dynasty.
On the "Shangxin Night" of the first lunar month of the Han Dynasty, Emperor Wu of the Han Dynasty held sacrifices to "Tai Yi" in Ganquan Palace, which was regarded by later generations as the precursor to the sacrifices to the gods on the fifteenth day of the first lunar month.
The introduction of Buddhist culture in the Eastern Han Dynasty played an important role in the formation of the Lantern Festival customs. During the Yongping reign of Emperor Ming of the Han Dynasty, in order to promote Buddhism, Emperor Ming of the Han Dynasty ordered that on the fifteenth night of the first lunar month, lanterns should be lit in the palace and temples to show the Buddha. Therefore, the custom of lighting lanterns on the fifteenth night of the first lunar month gradually expanded in China with the expansion of the influence of Buddhist culture and later the addition of Taoist culture.
During the Northern and Southern Dynasties, displaying lanterns during the Lantern Festival gradually became a custom. Emperor Wu of Liang believed in Buddhism, and his palace was decorated with lights on the 15th day of the first lunar month. During the Tang Dynasty, cultural exchanges between China and foreign countries became closer and Buddhism flourished. Officials and common people generally "burned lanterns to worship Buddha" on the fifteenth day of the first lunar month, and Buddhist lights spread among the people. Since the Tang Dynasty, lighting up lanterns during the Lantern Festival has become a legal matter and has gradually become a folk custom.
