Shadow play is a form of Chinese folk art with a long history. The actors or actresses in a shadow play are figures made of cow leather. Being controlled by one or several persons, these figures are reflected via light on the screen. Shadow play is most popular in the area of Shanxi and Gansu Provinces and often performed in the temple fairs, wedding ceremonies and funeral ceremonies, etc. With the purpose of driving out evil spirits, people wish that the performance of shadow play will bring them good fortune. Delicate and vivid shadow figures have become a kind of collection and are greatly loved by foreigners.
