The stage truss is usually composed of one or more platforms. Most of the main stage tables of the ancient amphitheater reach into the auditorium, lower than the audience (such as the stage of the ancient Greek fan theater), or higher than the audience (such as China Temple Table) for the audience to watch from three sides. The stage of an indoor theater is usually facing the auditorium, with a framed stage, an extended stage, and a center stage.
The stage design is based on the design of the "stage" as the subject matter. More specifically, the design of the stage equipment, lighting, curtains, sound, performance props, suspension and replacement of the support system, costumes, and makeup are taken as subject matter. What is similar to the display design is that these subject matter are "supporting actors" and should be the protagonists of "performance activities."

In terms of the degree of exquisiteness of stage design, it can be divided into three categories: open field platform, mobile stage, and indoor stage.

Audio, performance props, suspension and replacement of the support system, costumes, makeup, etc.; backstage including makeup, WenWenChang (band), cut-off channel, basic props, Chen Fang, and ready to play space.
