In the more than 200 years of Peking Opera, all the "singing, reading, doing, and fighting" on this stage have opened a unique history of culture and art of the nation, from "four Anhui troupes coming to Beijing" to "worship the dock" and wandering the Jianghu, from the "front and rear three tripods" of the court singing to the "four talents" of popularity all over the north and south, from the "four famous dans" of the country to the "four Kunling" On the stage, on and off the stage, in and out of the play, under the diffuse background of the historical beacon smoke, there are not only generations of actors who have soared to the sky or failed to recover, but also thousands of "opera fans" and "ticket fans" from the emperors and dignitaries down to the people who are fighting against the petty bourgeoisie.
