This story revolves around the folklore of "山娘娘", a white monkey spirit that possessed a newlywed woman in Qing dynasty China. A local道士,道士吴山, attempted to exorcise the entity through rituals, including using talismans and confronting the three-eyed deity. The woman returned to normal after the monkey was defeated and disposed of. It showcases the cultural beliefs and practices in dealing with supernatural entities during that time.
