This thesis can be divided into four parts.Firstly,Li Yus theory of ‘Structure’ is different from that of Aristotle.What
should be emphasized here is the distinction between Li Yus ‘one event’and Aristotlee.It thus corrects the improper comparison that has lasted for more than on decade in China.Secondly,Li Yus theory of
‘Kehun’(Buffoonery) is a mirror that can reflect the weakness of Western dramatic theory.The thesis takes the example of ‘Shakespearian Criticism’ to expound that Western dramatic critics ignored the value of ‘Kehun’.So Li Yus theory of ‘Kehun’ can also compensate for the weakness of the western dramatic theory. Thirdly, Li Yus
theory of ‘Practicism’ is 250 years earlier than that of Stanislavski,who has been cited alone in this reagard. However,Li Yus dramatic theory,including that expressed in his novels,is demonstrated to have a system of its own ‘Practicism’. Fourthly, both ‘Artpoétique’(1674) by Boileau and ‘Xian Qing Ou Ji’(1671) by Li yu are the influential dramatic words written in 17th centry;moreover,both were ‘eulogist’ and catered to the tendency of history. But regrettably in China, some scholare (including Lu Xun) condemnted Li Yu.
