Peking opera is a Chinese performing art that combines music, singing, acrobatics, dancing and historical drama. It became popular in the late 18th century as performances in the imperial court and for the public by 1884. There are four main types of performers distinguished by colored costumes indicating their rank or role. The stage features a square platform visible on three sides with a curtain separating the front and back, and a table for instruments, using minimal props with small items symbolizing larger things.
