This day's important activity is watching lanterns. Throughout the Han Dynasty (206 BC-AD 220), Buddhism flourished in China. One emperor heard that Buddhist monks would watch sarira, or remains from the cremation of Buddha's body, and light lanterns to worship Buddha on the 15th day of the 1st lunar month, so he ordered to light lanterns in the imperial palace and temples to show respect to Buddha on this day. Later, the Buddhist rite developed into a grand festival among common people and its influence expanded from the Central Plains to the whole of China.

"Guessing lantern riddles"is an essential part of the Festival. Lantern owners write riddles on a piece of paper and post them on the lanterns. If visitors have solutions to the riddles, they can pull the paper out and go to the lantern owners to check their answer. If they are right, they will get a little gift. The activity emerged during people's enjoyment of lanterns in the Song Dynasty (960-1279). As riddle guessing is interesting and full of wisdom, it has become popular among all social strata.

In the daytime of the Festival, performances such as a dragon lantern dance, a lion dance, a land boat dance, a yangge dance, walking on stilts and beating drums while dancing will be staged. On the night, except for magnificent lanterns, fireworks form a beautiful scene. Most families spare some fireworks from the Spring Festival and let them off in the Lantern Festival. Some local governments will even organize a fireworks party. On the night when the first full moon enters the New Year, people become really intoxicated by the imposing fireworks and bright moon in the sky.
