Abstract: Analyzing the rule of structural art in FAN Cuiting's 49 traditional operas,it mainly includes three aspects.The first is the organic unity of the whole structure. FAN Cuiting inherited the theory of one people one thing,male and female characters always being the main ones of stories on the stage. The second is the positive and nesative collocation in plots.The last one is to select dramatic scenes.The drama scenes related to the subject and the main line,can be selected since they can most accurately describe the events and shape the characters.
