Health communication plays an important role in spreading health information, improving residents ' health concept and improving residents ' health level. In the era of mobile Internet, with the change of media technology, the way of information dissemination is constantly evolving. The short video platform represented by Tik Tok has become a new position for health communication because of its short and concise content, wide communication channels, strong social attributes and various video forms. Especially after the outbreak of COVID-19 in 2020, health communication short videos have played an important role in spreading epidemic-related knowledge and refuting health rumors, expanding the influence of health communication.

In terms of narrative topics, " Medical Road Forward Weizi " can be divided into five narrative topics according to the content : life science, disease prevention, answering questions, first aid measures, diet and health preservation. In the narrative plot, it is found that " Medical Road Forward Weizi " spreads health knowledge by following the hot spots, attracting users, being close to life, spreading knowledge, not setting a title, and quickly cutting into the plot setting. In terms of narrative discourse, it mainly studies from two aspects : narrative perspective and audio-visual language.

On the one hand, it adopts nonlinear narrative structure to highlight key information around the theme. In terms of narrative methods, fragmentation narrative, hot narrative and story narrative are used. Based on the above analysis, this paper summarizes the problems existing in the short video narrative of health communication, and puts forward the following three suggestions for its development : to meet the needs of users with diversified narrative content, to adapt to the communication context of the new era with young narrative discourse, and to enhance the practical value of science popularization with multi-angle narrative skills.
