In the current context of urban development transformation and the gradual decline of historic and cultural districts, new demands have been raised for the preservation of such districts. The question of how to effectively safeguard historically and culturally significant districts, imbued with the vibrant essence of indigenous life, has become a topic worthy of contemplation. This paper takes the historical and cultural district of Leizhou Qu Street as a case study, using the concept of continuity of life as its focal point. Employing methods such as on-site observation, questionnaire surveys, and case studies, this paper investigates and evaluates the core community through identification and collaboration, and proposes corresponding preservation strategies and subsequent maintenance approaches. In doing so, the paper aims to achieve community identity, cultural heritage transmission, and the continuity of life. The findings reveal that the method of protecting the living heritage through continuity of life is applicable to historically and culturally significant districts that still thrive with the vibrancy of daily life, and this method can be effectively implemented. This research deepens our understanding of the concept of living heritage preservation in historic and cultural districts, further substantiating and implementing the principle of continuity of life in their preservation. The study also aims to provide valuable insights and references for the preservation of similar heritage sites.
