[2] Xu Xian, a young boy, once owned a pet snake in West Lake until his parents forced him to give her up.

In the end, Bai-Niang gives up her magical powers and remains in human form to prove that her love for Xu Xian is genuine.

The decision of a Chinese story being used as the concept blueprint came from Toei Doga president Hiroshi Ōkawa, who wanted to strike a tone of reconciliation with the Asian neighbors.

The film was a large scale major project, involving a total of 13,590 staff; surprisingly, it only took eight months to finish.

Historically, this film marked Tōei Dōga's first attempt to follow the example of American feature animation studios and become the so-called "Disney of the east."
