Known in Chinese as bian lian(bee-en lee-en) literally, “face changing”; a Chinese dramatic performance in which performers wear brightly colored costumes and several masks that quickly change., face changing is an important aspect of Chinese Sichuan operaa type of Chinese traditional opera that originated in Sichuan, southwest China.. Faster than the eye can detect, the masks of opera performers may change multiple times during a performance. One technique allows the performer to whisk away one facemask while another is pulled down from the top of the head by a series of silk threads attached to different parts of the costume. An actor can change seven different faces in sixty seconds. The secrets of face changing have been passed down from generation to generation, but only some two hundred individuals have mastered the art. Traditionally restricted to males, the practice of bian lian is now being learned by women as well. The colors of the facemasks range from green and blue to red, yellow, brown, and gold, and they depict emotions such as fear, tension, relaxation, slyness, desperation, and outrage.
