1. The Lantern Festival, also known as the Lantern Festival, Xiaozhengyue, Lantern Festival or Lantern Festival, is one of China’s traditional festivals and takes place on the fifteenth day of the first lunar month every year. The first lunar month is the first month of the lunar calendar, and the ancients called "night" "xiao". The fifteenth day of the first lunar month is the first full-moon night of the year, so the fifteenth day of the first lunar month is called the "Lantern Festival". According to the Taoist "Three Yuan" theory, the fifteenth day of the first lunar month is also called the "Shangyuan Festival". The Lantern Festival custom has been dominated by the warm and festive lantern viewing custom since ancient times.

2. The formation of the 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. Emperor Wu of the Han Dynasty worshiped "Taiyi" in Ganquan Palace on Xinye night of the first lunar month. "The activity was regarded by later generations as the precursor to offering sacrifices to the gods on the fifteenth day of the first lunar month. However, the Lantern Festival on the 15th day of the first lunar month truly became a folk festival after the Han and Wei dynasties. The custom of lighting lanterns on the fifteenth day of the first lunar month is related to the spread of Buddhism to the east. During the Tang Dynasty, Buddhism flourished, and officials and common people generally "burned lanterns to worship Buddha" on the fifteenth day of the first lunar month, and Buddhist lights spread all over 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.
