ABSTRACT
Taking the graduation ceremony of Peking University Health Science Center in 2020 as the observation object, this paper used Collins’ Interactive Ritual Chains Theory to analyze the form, theme and featured part of this ceremony from the dimensions of physical co-presence, barrier to outsiders, joint focus of attention and shared mood. It was found that the ceremony in medical colleges had an impact on the cognition, behavior and spirit of junior medical students in terms of group identity, emotional energy, group symbols and moral sense, which played a good role in professionalism education. Some enlightenment and thinking were obtained on this basis to provide some references for medical colleges to give full play to the educational function of the professionalism in the post-epidemic era.
