This report is mainly composed of the feminism to elaborate the set design of“Du Shiniang, Lady Du”, and ”Night, Mother”. Through feminism, we can clearly realize that the male social system in this world is the original problem caused the oppressions to female. I analyze the female characters in those plays to construct the possibility of their daily life in this society, and by doing this, I have gotten closer to their inner sides of private world. And then, in order to arouse the imagination of audience, I created the specific images composed on stage to connect characters (actresses), space, and materials in the theatre. With the specific images, audience can discover the creation principles from set designer, following these principles to construct a bridge of mind that connecting and arousing immediate self-conscious and personal experience with the “living” characters who are going to end up their own lives in the plays.
