The theory of “Three Drama Systems” originated from the “three drama views” proposed by HUANG Zuolin in Rambling on “Drama View” in 1962. Since then, SUN Huizhu has proposed two versions of the “Three Drama Systems”. At present, it gradually turns to focus on MEI Lanfang system. It leads to the discussion on the performance system of Peking Opera, the aesthetics of classical opera performance, and the performance system of Chinese opera. To clarify the origin, evolution, and debate of the “Three Drama Systems” is helpful to deepen the understanding of the relationship between traditional opera and modern drama as well as the relationship between MEI Lanfang and the aesthetics of Chinese opera。
