Abstract: The “Grand Aethetic Discussion” which took place in the fifties and sixties of 20th century exercised a moulding function to the late 20th century Chinese aethetics in the aspects of aethetic ideas and academic patterns.As far as its cultural background was concerned,it was the result of the interaction between the ideological reform movement in early period of People's Republic and Mao Zedong's literary principle of “Let a hundred flower blossom and a hundred schools of thought contend”;as to its academic origin,it was the transplantation of the former Soviet Union's aethetic contention.Philosophical aethetics was its greatest academic stipulation to the 20th century aethetics,and the strong political ideology was its deepest academic lesson.

Key words: Grand Aethetic Discussion, ideological reform movement, double hundred principle, philosophical aethetics, political ideology
