The face changing, or "bianlian" in Chinese,is an important intangible cultural heritage in China. only a few masters have grasped this skill. Actors change more than 10 masks in less than 8 minutes! By raising the hand, swinging a sleeve or tossing the head, an actor uses different masks to show different emotions, expressing invisible and intangible feelings through visible and tangible masks. From green to blue, red, yellow, brown, black, dark and gold, these masks show fear, tension, relaxation, slyness, desperation, outrage, and so on.
