Gui po (Chinese: 鬼婆; pinyin: guǐ pó; literally "old woman ghost") is a ghost which takes the form of a kind and friendly old woman. They may be the spirits of amahs who used to work as servants in rich families. They return to help their masters with housekeeping matters or to take care of young children and babies. However, there are also evil gui pos with hideous and hostile appearances like the witches in fairy tales.
