Wu Xuan's negation theory is based on the unique theoretical foundation of"ontological negation".By using his original critical and creative thinking,and through theoretical reflections on philosophy,aesthetics,and literary criticism,he has gradually formed the negation theoretical system,which is interconnected yet relatively independent among philos-ophy,aesthetics,and literary theory.This article explores the path of constructing Wu Xuan's negation theory by revie-wing the from the study of the current state of literary criticism,to the definition of original theory,and then to the for-mation and development of the theory,aiming to the path of constructing original Chinese theories,which can not only help researchers understand the negation theory but also provide a reference for the path of constructing original theories.
