Nü gui (Chinese: 女鬼; pinyin: nǚ guǐ; literally "female ghost") is a vengeful female ghost with long hair in a white dress. In folklore, this ghost is the spirit of a woman who committed suicide while wearing a red dress. Usually, she met with some injustice when she was alive, such as being wronged or sexually abused. She returns to take her revenge. A tabloid story tells of a funeral ceremony where family members of a murder victim dress her in red, hoping that her spirit will return to take revenge on her murderer. In traditional folklore, the colour red symbolises anger and vengeance in the context of ghosts. On the other hand, some ancient folk tales tell of beautiful female ghosts who seduce men and suck their yang essence or sometimes kill them. This type of female ghost is likened to the Succubus. Paradoxically, the male counterpart of a nü gui, a nan gui (Chinese: 男鬼; pinyin: nán guǐ; literally "male ghost"), is rarely depicted.
