Drama is mainly based on performing arts, and the core of performance is action. When investigating the role of stage art, we must study the relationship between stage art and action around the link of drama action, and focus on the comprehensive relationship between various elements to make an overall investigation.

Action environment actors often say that "the scenery is on the actors." In a circus, actors walk from place A to place B; As soon as I raise my hand, I cast my foot, that is, indoors and outdoors, upstairs and downstairs. Therefore, if all the functions of scenery modeling are unilaterally attributed to the specific characteristics of the plot, it will not only easily lead to the contradiction between scenery and performance, but also the repeated performance is meaningless in aesthetics.

Action decoration Stage decoration has two meanings in English: one is decoration and the other is scenery. Therefore, it is logical to regard decoration as one of the functions of stage art. Some people say that China opera is a "dramatic poem", and poetry pays attention to rhythm, which is the key element of decorative art.

Action space drama is a space art, independent of any stage form (extended stage or frame stage). Stage art is different from plane painting, it is to create a three-dimensional space suitable for dramatic action. For some traditional plays, in order to make the actors perform dance moves more easily and freely, an empty stage can be given in the design of dance beauty, and objects can be placed in the background of the sky or other places, but this operation method cannot be used as a treatment method for all plays.

The genre style of action figure affects the design conception of dance beauty and the formal treatment of modeling. Different types of plays can have different set styles. Style is also a mirror of the times. The simple and elegant modeling style of Han dynasty is different from the gorgeous and complicated modeling style of Qing dynasty, and the lively and upward modeling style of early Tang dynasty is also different from the plump and gorgeous modeling style of prosperous Tang dynasty.

The image of action connotation often has dual attributes: one is the natural attribute, and the other is that the artistic subject projects his emotional feelings, wishes and ideals on the object, "making things that are only physical appear human" (Zhu Guangqian's Letters on Beauty).
