Abstract: By the methods of literature review and expert interview, from the perspective of community order autonomy at the grass-roots level, the internal logic of Wushu group conflict and group autonomy is analyzed, and the reasons for the conflict of modern Wushu groups and the behaviors of destroying order are found.It is concluded that different types of conflicts in Wushu groups are caused by different "interest demands" and "shared cultures".In the traditional farming-economy society, Wushu group forms the internal control system of order autonomy by the social methods such as "rule of etiquette", "cooperation right", "memory public opinion" and so on. But, with the changes of modern social structure and economic system cutting the relationships among the different groups, the new contradictions and conflicts in Wushu groups are in the "gap period" of supervision. The suggestions are made to improve the order autonomy of modern Wushu groups through the measures of "combination of etiquette and law", "cultural identity", "information supervision" and so on.
