Since the 20th century,the disputations between Tang poetry and Song poetry in Ming poetics ,to the academic`s opinion,have became more and more important. The population of people who research this question and conduct their own thinking to this topic has added a lot.But there are still several problems:First, educational circles pay more attention to the relationship between the poetry and court administration,Secondly,they waste a lot of time on the submicroscopic researches on the works of few masters,but ignore the attitude of micro-examing in the comprehensive and systematic study of the Tang and Song poetry.The third they are used to bring in the western poetics of literary and artistic concept and methodology to explain the phenomenon of the Tang and Song poetry, carelessly classifying the Tang and Song poetry realism or romanticism.And also they superficially introduce in some Western fashion terminology,but abandoned a set of concepts, categories, regulations, properties in aesthetic taste and cultural attitudes of the Ancient Chinese Literature and Poetry. It was so called foreign things service China,but in reality ,it is procrustean.
