What is the origin of Lantern Festival?

Lantern Festival, also known as Shangyuan Festival, is the first full moon night celebrated by people in a year. According to the "ternary theory" of Taoism, the fifteenth day of the first month is Shangyuan Festival, the fifteenth day of July is Zhongyuan Festival, and the fifteenth day of October is Xiayuan Festival. The officials in charge of the upper, middle and lower elements are heaven, earth and man respectively. The celestial officials are happy and the Lantern Festival should be lit. The custom of lighting lanterns and setting off fireworks on the Lantern Festival comes from this saying.

The gods worshipped by Wudou Midao, an important school of Taoism in the late Han Dynasty, were celestial officials, local officials and water officials. They said that God bless the people, the local officials forgive sins, and the water officials relieve Eritrea. They used three yuan to match the three officials, saying that Shangyuan Tianguan was born on the fifteenth day of the first month, Zhongyuan was born on the fifteenth day of July, and Xiayuan Shuiguan was born on the fifteenth day of October.

In this way, the fifteenth day of the first month is called Shangyuan Festival. In the Southern Song Dynasty, Wu said in a dream: "The fifteenth day of the first month is the day when God bless the people." Therefore, lanterns should be lit on the Lantern Festival.

As far as the length of festivals is concerned, there is only one day in Han Dynasty, three days in Tang Dynasty and five days in Song Dynasty. In the Ming Dynasty, lights were lit from the eighth day of August until the seventeenth night of the first month, a total of ten days.

Connected with the Spring Festival, it is a city during the day, full of excitement, and brightly lit at night, which is spectacular. Especially the exquisite and colorful lights make it the climax of entertainment activities during the Spring Festival. In the Qing Dynasty, there were more "hundred operas" such as dragon dancing, lion dancing, dry boating, walking on stilts and yangko dancing, but the festival period was shortened to four to five days.
