(original Chinese title: Liao Zhai Yan Tan ) is a 1990 Hong Kong erotic horror film directed by Lam Ngai Kai. It is one of the most notable entries in the "Category III" genre of Hong Kong cinema—a classification denoting films restricted to adults due to extreme violence, sexuality, or horror.

The plot follows three beautiful sisters—, Pai So-So , and Fei-Fei —who are actually fox spirits (vixens) that have meditated for 1,000 years to shed their animal forms and become human. To complete their transformation, they must spend one final month in the human world while adhering to strict Taoist virtues.

: This film should not be confused with the mainstream 1990 American blockbuster

Despite the title, there are technically no ghosts. The protagonists are fox spirits —supernatural entities common in Chinese folklore—who can take human form.
