The Sorcerer and the White Snake

At its most basic, the story tells of a young scholar who falls in love with a beautiful woman, unaware that she is a thousand-year-old white snake that has taken on human form. A monk intervenes in order to maintain nature's law and casts the white snake into a deep well at Leifeng Pagoda.
