Ji Yun (紀昀) was very outstanding and contributed to the academics in Qing Dynasty. Besides editing the Summary of Si-Ku-Quan-Shu (《四庫全書總目題要》), he also posed a lot of comments in Yu-Tai-Xin-Yong (《玉臺新詠》), Poems of Wang xi-sheng (《王溪生詩說》), Poems of Su Wen-zhong-gong (《蘇文史公詩集》), Ying-Qui-Lu-Sui(《瀛奎律髓》) and Wen-Xin-Diao-Long (《文心雕龍》). Zhu Dong-run (朱東潤) thought that in ancient times crtiics all were devoted to criticizing, and no one could compete with Ji Yun. The comments were sincere but neither superficial nor sound at all. Nevertheless, the achievement of daring to criticizing is certainly with the profound vision of criticism so that all details could be perceived and all comments made sense. Observing the argumentation of the Summary of Si-Ku-Quan-Shu, it kept complimenting on Liu Xie (劉勰) and held him in high esteem, but the viewpoint of criticism in Wen-Xin-Diao-Long is even the benchmark of the researches shifting from the general comment and investigation to the theoretical analyses in Wen-Xin. Moreover, Wen-Xin-Diao-Long was definitely the important basis for engaging in academic researches, and the theoretical thinking of Liu Xie was also profoundly dwelt in the system of Ji Yun’s literature criticism. There was the close relationship of handing down from deducing the compromised thinking of both Liu’s and Ji’s the theoretical system constructions. For this reason, the topic was drafted and intended to discuss it by three aspects: (1)the strictly criticism and simultaneous reflection on the fraudulent practices at that time, (2)the rule recognition of literature evolution and the compromised thinking and (3)the establishment of theoretical systems and the compromised thinking.
