Peking opera is China's traditional theater art form that combines music, singing, acrobatics, dance and pantomime. Students undergo rigorous training from a young age to master roles like Sheng, Dan, Jing and Chou. Performances utilize symbolic costumes, masks, props and staged conventions to convey meaning. Musicians are visible on stage to provide accompaniment for songs, speeches, fights and dances that portray different characters and stories according to Peking opera's aesthetic principles.
