Lantern Festival is one of the traditional festivals in China, which existed in the Western Han Dynasty more than 2, years ago. Lantern Festival viewing began in the period of Emperor Han of the East China. Ming Di advocated Buddhism, and heard that on the 15th day of the first month of the first month, monks observed Buddhist relics and lit lanterns to worship Buddha, so that all the gentry and ordinary people hung lanterns on that night. Later, this Buddhist ceremonial festival gradually formed a grand folk festival. The festival has experienced the development process from the palace to the folk, from the Central Plains to all parts of the country. During the reign of Emperor Wen of the Han Dynasty, the fifteenth day of the first month was named Lantern Festival. During the reign 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 who rules everything in the universe. When Sima Qian founded the "taichu calendar", he had identified the Lantern Festival as a major festival-Lantern Festival. Another theory is that the custom of burning lanterns in Lantern Festival originated from the Taoist "three-yuan theory"; The 15th day of the first month is Shangyuan Festival, the 15th day of July is Zhongyuan Festival, and the 15th day of October is Xiayuan Festival. The officials in charge of the upper, middle and lower three elements are heaven, earth and man respectively, and the heaven official is happy, so the lantern festival should be lit. The festivals and customs activities of the Lantern Festival are extended and expanded with the development of history. As far as the length of the festival is concerned, it was only one day in the Han Dynasty, three days in the Tang Dynasty, and five days in the Song Dynasty. In the Ming Dynasty, the lights were lit from the eighth day of the eighth month until the night of the seventeenth day of the first month, for ten days. Connecting with the Spring Festival, the day is the city, which is very lively, and the lights are lit at night, which is spectacular. Especially the exquisite and colorful lights make it the climax of entertainment activities during the Spring Festival. By the Qing Dynasty, there were more "hundred plays" such as dragon dancing, lion dancing, roller boating, walking on stilts and dancing yangko, but the festival period was shortened to four to five days. Shangyuan means the first full moon night in the new year. The origin of Shangyuan Festival is recorded in Miscellanies at the Age of Years, which is a Taoist stereotype. Taoism once called the fifteenth day of the first month of the year Shangyuan Festival, the fifteenth day of July as Zhongyuan Festival, and the fifteenth day of October as Xiayuan Festival, which were collectively called "Sanyuan". The gods worshipped by Wudou Midao, an important faction of Taoism at the end of Han Dynasty, were Tianguan, Diguan and Shuiguan. They said that heavenly god blesses the people, the Diguan pardoned sins and Shuiguan relieved Eritrea, and they matched three officials with three yuan, saying that Shangyuan Tianguan was born on the 15th of the first month, Zhongyuan Diguan was born on the 15th of July and Xiayuan Shuiguan was born on the 15th of October. In this way, the fifteenth day of the first month is called Shangyuan Festival. In the Southern Song Dynasty, Wu Zimu said in Dream Liang Lu: "On the fifteenth day of the first month, it is the day of heavenly god blesses the people in Shangyuan." It is said that heavenly god blesses the people, the local officials forgive sins, but the real motivation of Lantern Festival custom is that it is at a new time point, and people make full use of this special time stage to express their wishes for life.
