The Ghost Festival, also called the Hungry Ghost Festival, is held on the 15th day of the seventh lunar month. Both Buddhists and Taoists celebrate this festival. The belief is that the gate to the underworld opens on the first day of the seventh lunar month. This month is regarded as the Ghost Month. All of the ghosts and spirits are released from hell. They are free to wander for the whole month. People hold ceremonies to welcome the ghosts and spirits.
