The contemporary great scholar Qian Zhongshu is fully versed in both ancient and modern, Chinese and Western theory, and has numerous opinions on poetry criticism. Although these criticisms are not systematic, one can get his overall view about the aesthetics of poetry by careful inspection and research of the implications of his criticism, as well as through mutual analogy. In his criticism, Qian Zhongshu often introduces Du Fu's poetry to be a basis of his theory. No one in academic circles, however, has gone deep into the connotations and meanings of Qian's poetic theory. Therefore, I intend to address several points of view in Qian's works, in order to present an academic analysis of Qian Zhongshu's theory on Du Fu's poetry. The main content includes: 1. ”Take the qilü of Du Fu as an example”, in order to discuss the constant imitations of Du Fu's poetry and the profound meaning of Qian's ”yang (example)”, which is often utilized as a term in his poetry criticism. 2. ”Beizong and Du Fu”, to show the aesthetic trend of Chinese poetry through the style of Du Fu's poetry, which does not need to be concise or kept away from excessive ornamentation. 3. ”The influence of Du Fu's poetry”, which abstracts from Qian's comments about Du Fu's poetry to conclude the general influence of Du Fu's poetry on literary history, theory, and criticism. Taking Qian's poetry as an example to explain Du Fu's poetry not only has the merits of aesthetics, but is also a specific symbol of Chinese culture.
