RESUMEN
The implementation of the "Healthy China" policy is inseparable from public health. The improvement of the national health level, the control of health risk factors and the improvement of health service ability and other aspects need to rely on the talent training and discipline construction of public health and preventive medicine in medical colleges, which highlights that the public health discipline construction and development of our country has a certain lag and limitations: unprofessional public health academic team and disciplines; separation of teaching research and practice in public health; lack of public health expertise and insufficient personnel scale; health emergency and legal system that do not match economic development, etc. Therefore, in order to promote the construction of healthy China, we should promote the integration of public health disciplines, strengthen the teaching and practice of health emergency response, improve the health emergency response and dynamic monitoring system focusing on prevention so that we can make public health disciplines both scientific and contemporary.
