As vital repositories of urban history and culture, historical districts encapsulate both tangible memories and the fabric of social life. However, current renewal practices in China predominantly emphasize the physical spatial form, often neglecting the value of daily life. This oversight leads to issues such as commercial homogenization, cultural loss, and the erosion of local identity, potentially triggering spatial symbolization and gentrification conflicts. To reshape the organic order of these districts, it is crucial to recognize self-organizational principles and focus on the grassroots power of public participation. This study examines the Nanhuaxi historical district in Guangzhou, focusing on the informal spaces spontaneously created through residents' self-initiated modifications.
