Abstract: This article examines several representative definitions of "Wushu", which are respectively given from the perspectives of sports, physical education, body, and comprehensive theory. Most of the definitions are derived from formal logic, and classify Wushu as a superordinate concept. This paper analyzes the problems with the definitions, which include that the definition from the perspective of physical education cannot fully accommodate Wushu, misuse of the "ontology" category, the body theory is abstract and hollow, and the comprehensive theory is not comprehensive at all. The paper further points out that even though Wushu can be defined in different ways, any definition can only focus on an aspect because of its holistic feature. For example, the method of genus+species difference cannot reveal the nature of Wushu. The law of excluded middle is not fully applicable to the life world in which Wushu exists. Even so, this does not mean that we can not give a descriptive definition to Wushu.

Key words: Wushu, the concept of Wushu, Kinematical theory, sports theory, synthesis theory
