Abstract: The expressionism theoretical system,scribble concept system,the system of Wen Xin Diao Long,and the humanism poetic system centered by “protoplast” theory,are the representative ideas of ancient literature criticism.From the existing four structural systems we can see that background knowledge,or the foregrounding in the structural system has become a decisive factor to restrict the system construction,therefore surpassing the previous systems has become the latest trend in the systematic research and construction.Among these efforts,several motivations are worth consideration.To overcome the unilateralism brought forward by previous presumption,it is worthwhile to depend on the mutual support of theoretical frame and empirical facts,to depend on the accurate and objective reproduction of the various phenomena within the field of ancient literature criticism.The reversion of historical and empirical facts to theoretical construction should be put in the first position. In the system construction,we can not put logo centrism as the discourse activity pry,instead,we should conduct it on an equal condition.Too early systemization will lead to errors in concept and model.

Key words: classical literature criticism theory, system, status quo, reflection
