Piying is shadow puppetry. Flat figures cut from hide are held against a lit cloth screen and moved by rods, so that the audience sees only their moving shadows while a performer sings or speaks the story. It is a folk theatre that is centuries old and tells legends, histories and romances. In The Legend of Zang Hai the shadow puppets act as a second narrator.
