Abstract: In order to consolidate basic theories about Wushu, firstly, in terms of formal logic and specific content, the authors dissected problems existing in the new definition of Wushu which was given at the national level, and pointed out the followings: in terms of form, the most prominent problem is the mixing up of “definition” and “concept”; in terms of specific content, major problems include inaccurate connotation definition, chaotic category relationship, neglecting traditional Wushu in the establishment of extensions, ignoring the differences between “de-marcation” and “division” etc. Aiming at the said problems, the authors corrected the new definition from the per-spectives of concept connotation and extension, according to requirements for concept definition by applying formal logic. Lastly, the authors formed two types of Wushu concepts from such two perspectives as “property definition” and “occurrence definition”.
Key words: traditional national sport；new definition of Wushu；formal logic
