This article aims to explore and extend the research in Hugo's dramas in the features of the groundbreaking characteristic style of works, the craticism of the narration by the method of using the past to disparage the present, or even investigate the social chain effect at that period. Hugo, himself, was a poet with emotional and refined thoughts who contructed purposely the Pan-European universal value, and exploited the strong tension of drama to impact directly on the appeals of the classicalism. The intention of the author is to incite the audience to understand the intense feeling of the impact of the class differential and the craving of the social justice while they watch this kind of history-based dramas. The purpose of this ariticle is to take Hernani and Ruy BIas as the research objets to verify the reproduced authenticity in Hugo's history, and the writing intention of lingering purposely on the space of the warp of truth and fiction. In the final, we are going to analyze the characteristics of cross-style writing in these two dramas.
