As a city rich in historical and cultural heritage, Guangzhou has made substantial efforts to protect and revitalise its historic districts. This study examines Yongqing Fang, a well-known commercialised historic district in Guangzhou, to understand how tourism-driven development reshapes everyday life and the interactions among its diverse users. Using comparative analysis, interviews, and NVivo 12 coding, the research explores how longstanding residents and newer occupants adjust to the rapidly evolving environment. The findings reveal that urban renewal and commercialisation have undermined local culture and social networks, altering how spaces are used. While lifestyle differences are evident among different user groups, the study also highlights instances of alienation and conflict, as well as moments of positive interaction and mutual support. The research emphasises the importance of inclusive strategies in heritage renewal and raises the question, drawing attention to the challenges faced by marginalised users in commercialised historic districts. It offers recommendations for policymakers, urban planners, and other stakeholders to balance heritage preservation with the social and economic needs of communities, fostering sustainable integration of tourism and local life in historic districts.
