"Waiting" is one of the terms of Peking Opera. It means that before actors are about to go on stage, they wait behind the scenes to make preparations. Peking Opera, also known as Ping Opera, Peking Opera, etc., is the most influential type of opera in China, with Beijing as the center and spread throughout the country.

Peking Opera has a set of standardized artistic expressions in various aspects such as literature, performance, music, and stage art. The singing style of Peking Opera is a variation of the Ban style, with Erhuang and Xipi as the main voices. The accompaniment of Peking Opera is divided into two categories: the literary stage and the martial arts stage. The huqin is the main instrument in the literary stage, and the drum board is the main instrument in the martial arts stage. The roles in Peking Opera are divided into roles such as Sheng, Dan, Jing, Chou, Za, Wu, and Liu. The latter three roles are no longer exclusive. Each profession has its own set of performance routines, and each has its own unique skills in singing, chanting, and beating. Peking Opera takes historical stories as its main performance content. There are more than 1,300 traditional repertoires, and more than 300 to 400 are frequently performed.
