In some places, it is also called "Ghost Festival" and "Stone Drum". This is a Buddhist ceremony in India.

The story of Manglietia chrysantha saving agaric is widely circulated among the people: "People with Manglietia chrysantha monks have great strength. His mother fell into the hungry ghost road, and the food mouth turned into flames. Hunger was too bitter. Unable to save his mother, Mu Lian asked the Buddha for advice. In order to talk about the Lanpen Sutra, she taught July 15th to make a Lanpen to save her mother. "

China followed this practice from the Liang Dynasty and became the Mid-Yuan Festival. But later, in addition to setting a fast for monks, activities such as repentance and setting fire to burners were added.
