This paper, using Foucault's genealogical method, aimed to investigate historical details and policies of school corporal punishment and to understand school disciplinary techniques in different periods and the formation and impact of zero-corporal punishment policy. This paper found that corporal punishment had its unique historical background and was one of the school disciplinary techniques, that revised Educational Fundamental Act was the result of power conflict and struggle, that zero-corporal punishment policy produced discourse and deterred school from corporal punishment but did not make school change discipline or rectify campus problems, and that self-cultivation practice might be a new direction for schooling. Finally, according to the explored results, this paper offered conclusions and suggestions.
