Jin-shan Temple, an excerpt from The Legend of the White Snake, tells of a woman who is reincarnated from a white snake and goes to the temple to meet her lover who is in dispute with a monk. The white snake gets furious and they fight with tricks.

Face-changing was demonstrated by an evil-spirit male character, while dancing, singing, kung fu and acrobatics were also used.

Face-changing is a closely-kept secret movement where a character, by quick manipulation of a mask, literally changes the face they show to the audience in a split-second.

On Saturday, the troupe dropped in to the Museum of London Docklands, offering visitors, most of whom were children, a close-up look at the opera and first-hand experience on how to be a star on a stage through a workshop.

From simple steps and gestures, to how to tell different characters apart by costume and makeup, director Shen gave the audience a clear walkthrough, demonstrating by herself and with her troupe.

The museum audience was then treated to a comic turn entitle A Roller with Oil Lamp on Head, a highly skilled performance played by a clown, who has a lighted oil-lamp on his head and rolls like an acrobat.
