A magician changes faces, a traditional Chinese opera technique called Bian Lian, through a combination of physical methods and misdirection. Key techniques include layering and quickly pulling off silk masks with hidden strings attached to the costume, using dust to temporarily obscure the face, and spreading concealed greasepaint with a hand or sideburn to alter makeup. The audience's attention is diverted by elaborate dance moves, quick head turns, or the swipe of a fan, making the nearly instantaneous transformation appear magical.
