Abstract:Ling Shu kept close contact with the Tongcheng School.In the beginning of the 20th century,the Tongcheng School was reproached frequently,while Ling Shu spoke in defence of it to the most.But,Ling Shu did not completely approve of the terms of the Tongcheng School.Ling Shu regarded that the Tongcheng School was a school of literature criticism,not a school of literature.Fang Bao's thorey of Yi Fa and his relevant practice of literature criticism represented the basic thought of the Tongcheng School.Ling Shu accepted the thought of Tongcheng School and put Fang's theory of Yi Fa into the literature criticism practice especially,and developed the theory.Ling Shu made a great comtribution to the Tongcheng School,and was an important member of the Tongcheng School.
