1. The first month is the first month of the lunar calendar. The ancients called night night, and the fifteenth day of the first month is the first full moon night in a year, so it is called Lantern Festival, also known as Shangyuan Festival.

2. Lantern Festival is mainly a series of traditional folk activities, such as watching lanterns, eating glutinous rice balls, solve riddles on the lanterns and setting off fireworks.

3. In many places, traditional folk performances, such as Youlong lanterns, lion dancing, walking on stilts, boating, yangko and playing Taiping drums, are also added to the Lantern Festival.

The formation of the Lantern Festival has a long process, which is rooted in the folk custom of turning on lights and praying for blessings.

According to general data and folklore, the fifteenth day of the first month was paid attention to in the Western Han Dynasty, but the Lantern Festival on the fifteenth day of the first month really became a national folk festival after the Han and Wei Dynasties.

6. The rise of the custom of burning lanterns on the fifteenth day of the first month is also related to the eastward spread of Buddhism. Buddhism flourished in the Tang dynasty, and officials and ordinary people generally lit lanterns for the Buddha on the fifteenth day of the first month, so Buddhist lanterns were spread all over the people. Since the Tang Dynasty, it has become legal to put lanterns on the Lantern Festival.
