1955 film directed by Billy Wilder

As a young boy, Xu-Xian is forced to free his pet, a small snake. Unbeknownst to him, the snake is actually a young snake goddess named Bai-Niang and she is in love with him. Many years later, when they are both adults, the princess is magically transformed into a human and sets out to find her love. But the local wizard believes her to be a vampire, and banishes Xu-Xian from the village in order to save him. Xu-Xian's pet pandas Panda and Mimi set out to save him and bring him, in the process becoming leaders of an animal gang.

A workman finds a singing frog in the cornerstone of an old building being demolished. But when he tries to cash in on his discovery, he finds the frog will sing only for him, and just croak for the talent agent and the audience in the theater he's spent his life savings on.

The film takes place during work on the water reservoir, outside Beijing's Ming Tombs, in 1958 at the beginning of the Great Leap Forward. The film follows how workers and leaders are working together to get it done. The film's final 25 minutes is a future interpretation of how it will look like 20 years after it has been completed with the water reservoir.
