The Liyuan theatre has hosted classic Peking Opera performances since 1999 with it's grand opera hall that can fit up to a thousand visitors. The hall has brought up the atmosphere through design and decorations similar to old Beijing opera theaters. These decorations include walls aligned with chinese couplets and calligraphy, opera masks and Chinese folding screens (pingfeng). Peking opera features four main role types, sheng (gentlemen), dan (women), jing (rough men), and chou (clowns). Performing troupes often have several of each variety, as well as numerous secondary and tertiary performers. With their elaborate and colorful costumes, performers are the only focal points on Peking opera's characteristically sparse stage. They use the skills of speech, song, dance and combat in movements that are symbolic and suggestive, rather than realistic. Above all else, the skill of performers is evaluated according to the beauty of their movements.
