Abstract: Caused by history,culture,aesthetic standards,etc.post Tang Yuefu poems of the 6 dynasties of Song,Liao,Jin,Yuan,Ming and Qing are qualitatively changed and apparently different from those of the 2 dynasties of Han and Tang,Viewing it from the perspective of famous Yuefu pieces,post Tang Yuefu poems fall into 2 categories of old and new themes.Neco theme Yuefu consists of extempore,Gexing and Zhuzhi Yuefu.In the study of Post Tang Yuefu poems,it won′t do to scrutinize the works in the same light as with Han and Tang Yuefu poems.The thesis of “non Yuefu Gexing” by Matsuura Misasuke,a Japanese scholar,is utterly inconsistent with the reality of post Tang Yuefu poems and cannot be used to define post Tang Yuefu Gexing.

Key words: Yuefu(folk songs and ballads in Han style) poems, post Tang Yuefu, old theme, new theme, Gexing Yuefu(that can be set to music and sung), Zhuzhi Yuefu(folk songs or poems in the classical style with love as the theme or portraying local conditions and custom)
