The development of school physical education cannot be carried out without policy guidance, while the key to the realization of policy objectives is implementation. Through analysis the authors concluded that problems such as fragmentized implementation characterized by "division between departments", mandatory implementation characterized by "ultra strong control", superficial implementation characterized by "implementing the less important policies but ignoring the important policies", and movement style implementation characterized by storm like implementation etc, had affected the in-depth furthering of school physical education policies. The authors pointed out that under the background of deepening comprehensive reform, school physical education policy practice must, under the guidance of modern governance theories, realize the changes from fragmentized administration to comprehensive governance, from mandatory control democratized furthering, from superficial implementation to in-depth furthering and from movement style management to normalized governance. Specific strategies include the followings: overall control and handle all sorts of complicated relationships in policy implementation; innovate on policy implementation mechanisms, promote the formation of a new situation of school physical education governance; realize in-depth and normalized policy implementation, etc.
