The Mad Woman's 18 Years

The Mad Woman's 18 Years is a Taiwanese true story about a woman who was clinically insane. Her tragic fate—being sent to a Buddhist temple and eventually confined in a cage for eighteen years—has become a well-known Taiwanese folk tale. Set in a time before psychiatric hospitals, families often confined mentally ill members, only providing basic care. The story was adapted into several films and TV adaptations.
