In response to the challenges posed by an aging society, palliative care and hospice have been introduced and promoted as crucial components in constructing a comprehensive Health Care System for the Elderly. There has been a notable shift in the discourse surrounding "death", transitioning from a traditional taboo to an openly discussed topic. This trend has sparked increased scholarly interests in death discourse.Our study focuses on the death discourse literacy of medical professionals, exploring how doctors communicate end-of-life care and life care issues with patients and their families in a Pain Management Clinic. The research was conducted at a public hospital in Beijing, recognized as a model base for hospice. Ethnographic methods were used to observe and collect data on doctor-patient communication in everyday clinical practices. Audio and video recordings of doctor-patient conversations were collected and transcribed for systematic analysis. The study found that doctors' death discourse literacy is primarily demonstrated through life care conversations with patients and their families. Experienced doctors typically employ a "Three-step Perspective Display Method" to facilitate these discussions. The method was illustrated with concrete instances taken from the data. The paper then discusses in detail the implementation of the first step, inviting patients to display their perspectives, from two aspects: direct invitation and indirect invitation. Through the analysis, this paper offers practical patterns and models for clinical practitioners to improve the quality and effectiveness of communicating end-of-life issues and conducting life care and education, particularly in clinical settings.
