"Living Will" is a legal document in which people express their medical and related wishes for the end of their life in advance when they are conscious, and currently is a new genre of death discourse in China. This study examines the discursive practice of "living will", in particular the attitudes of the elderly towards good death and living wills through semi-structured interviews with 8 elderly people in North China. From the perspective of transitivity of systemic functional linguistics, the interviewees describe unsatisfactory death with material processes such as unnecessary rescue and tortured behavioral and psychological processes; in terms of evaluation, the interviewees used appropriate judgments, happy and satisfaction affects such as peaceful, dignified and painless death in the company of relatives. Regarding the living will as a means of defending the right to a good death, the respondents agree with its concept, and support and embrace its promotion activities, but the willingness to fill out the living will varies from person to person, mainly affected by ability, age and institutional factors.
