In recent years, residential care has become an alternative option for elder care in Beijing, China. Little is known, however, about the well-being of elderly residents and the relationship between their health and living in residential care facilities (RCFs). Hence this research aims to understand the well-being of elderly residents in RCFs and how the environment of RCFs affects elderly people's everyday activities and health. The concepts of therapeutic landscapes, active aging, and well-being contribute to understanding the relationships among aging, health, and environment within RCF settings. Qualitative data from 46 in-depth semi-structured interviews with RCF managers, elderly residents, and family members in Beijing were transcribed and analysed using the constant comparative method. The results show that most of the elderly residents are satisfied with their lives in RCFs, but a few of them feel isolated and depressed after their relocation. Each RCF, as a place with its unique physical and social environment, has a significant influence on the elderly residents' physical and psychological well-being. Individual factors such as characteristics of elderly residents, their attitudes on aging and residential care, and family support also play important roles in their adaptation and well-being after relocation from home to RCFs. Although this study focuses on residential care at the local level, it sheds light on future research on geographical and socio-cultural meanings of elder care at local, regional, and national levels in China.
