The stage background picture has nothing to do with genre and genre. Different theaters in China have their own unique stage background pictures. Generally speaking, the audience who often go to the theatre will know which theater China is by looking at the stage background. The background map corresponds to the theater one by one, regardless of genre or genre. No matter what genre, no matter what genre, you always use the same background picture when you come to a theater to perform.
Of course, with the exception of new dramas with big production and big investment, all of them set a variety of backgrounds according to the plot, and often change a scene, which means that a drama needs to change several background pictures.
