To fully exploit the significant role of public physical education in the process of "fostering virtue through education" in universities, this study provides a theoretical interpretation of the knowledge-action perspectives on public physical education held by university presidents in the new era and examines the existing issues. Based on this, corresponding strategies are proposed. These include: emphasizing both recruitment and cultivation through multiple measures to strengthen the construction of the public physical education faculty team; implementing scientific evaluations and precise designs to improve the accuracy of workload statistics for public physical education teachers; exploring diversified funding channels to optimize the public physical education facilities; standardizing testing and providing timely feedback to enhance the implementation of universities students' physical health assessments, among others. The research results provide a useful reference for colleges and universities to finally realize the fundamental task of "foster virtue through education".
