Unlike other celebrations of the dead in Eastern cultures that seek to honor dead ancestors, the Hungry Ghost Festival seeks to pacify the hungry ghosts, the ghosts of strangers and the un-cared-for dead. These are the ghosts of those who died by their own hands, by accidents, by drowning or hanging who have been denied entry into heaven. Angry because they are forced to dwell in hell without food or comfort, when released, they search for souls to take their place in misery.
To Taoists(道教徒) and Buddhists(佛教徒), these evil spirits are not to be taken lightly. They are most active at night and can take many forms including: snakes, moths(蛾), birds, foxes, wolves, and tigers. They can even appear as beautiful men or women to seduce the living. When they possess an individual by entering the body they cause illness and mental disorders.
The most important days of this month are the 14th and 15th, the days of the great feasts. On the 14th, a great feast would be held to honor family ancestors. Prayers and offerings would be made at family altars. On the following night, the 15th, they would feast for the hungry ghosts. Held outside under the full moon, these feasts feed the evil spirits so that they will leave the living alone and bribe(贿赂) the ancestors for luck with money and the harvest.
