As the main body of epidemic prevention and control, public hospitals are more professional, authoritative and credible. They are important participants and main parts of epidemic prevention and control propaganda. The doctor-patient relationship was once unprecedented harmonious. On this basis, the trust established is more stable, so how to build a long-term and good doctor-patient interaction based on this trust in the post-epidemic era is an important way to build the social reputation of the current public hospitals. To maintain and consolidate this harmonious relationship, the convergence media still have a great research space and broad practice platform in top-level design, agenda setting, channel development and ethical self-discipline of practitioners. Based on the interactive paradigm of convergence media and the new model of Internet medical treatment, this paper explores a new model in line with China’s national conditions, namely, “filial piety relationship model”, which is of great significance to the long-term maintenance of harmonious and friendly medical relations.
