Seeing a Peking Opera performance for the first time, a foreigner would wonder: why are faces of actors painted red, white, black, yellow or green? Are they masks? But masks are separate from the face. Facial make-ups in Peking Opera are different from masks. Intrigued, many foreign tourists would go backstage to see actors and actresses remove stage makeup and costume. Next time, they would go there before a performance starts to see how performers do their makeup. Luciano Pararotti, the great tenor of international fame, once had a Peking Opera actor paint on his face the makeup of Xiang Yu, a valiant ancient warrior portrayed in numerous Peking Opera plays.
