This paper takes the expression "complete beauty" from A Dream of the Red Chamber as a starting point and combs through the Double Image theory of critics and Robert Rogers's Double theory quoted by professor Ou Li-Chuan, as well as the "alter ego" proposed by Edward Lam. The author attempts to analyse a transition of interpretation along a vertical timeline, and further on explain the meaning and value that this interpretation gives to the processes of "novel to drama" and "traditional literature to modern spirit". The interpretive perspective of Wang Xifeng and Xiao Hung being mutually "alter egos" possesses both the discovery and construction of similarities of the Double Image theory while, horizontally, it builds the link between classical novels and modern theatre as well as that binding modern theatre with the modern spirit. The author hopes to unravel a different perspective for the reader to re-examine classical novels in a new light so as to discover in them contemporary meaning and value.
