Gui po (Chinese: 鬼婆; pinyin: guǐ pó; lit.: 'old woman ghost') is a ghost that takes the form of a peaceful 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 take care of young children and babies. However, there are also evil gui pos with disgusting and violent appearances.
