"Like poet like poetry"has been a traditional point of view of Chinese ancient literary criticism.Since "tz'u" had been evolving from lyrics to the poets' expressions of their own emotions ideals, the tz'u critics began to notice the influences of the poets' moral and personality on "tz'u" compositions. Even though there were discussions about the relationship between the grades of tz'u and the poet's character, these discussions were either crude, short, or scatteredly limited to only one poet. Until to the late Qing dynasty, the critics started to delve into the relative discussions between the grades of tz'u and the poet's character, Thus, I aim to take the late Qing dynasty critics, Liu xi-zai, Jiang shun-yi, Xie zhang-ting, Feng xu, Chen ting-zhou, Shen xiang-long, Kuang zhou-yi, and Wang guo-wei as my research targets, to discuss about their different explanations for the grades of tz'u and the poet's character. I hope to attain the developing sequence and the virtual meanings of "the degrees of Tz'u and the poet's character" in literary criticism convention.
