E gui (traditional Chinese: 餓鬼; simplified Chinese: 饿鬼; pinyin: è guǐ; literally "hungry ghost") refer to ghosts which appear during the Ghost Festival. They are believed to be the spirits of people who committed sins out of greed when they were alive, and have been condemned to suffer in hunger after death. The e gui has a mouth which is too small for ingesting food and is covered with green or grey skin, sometimes with a potbelly. The ghost suffers from insatiable hunger. It haunts the streets and kitchens, searching for offerings and decomposed food. These hungry ghosts consume anything, including excreted waste and rotten flesh. There are various types; some have fire-breathing abilities while others suffer from anorexia.
