With the increasing emphasis on historical and cultural heritage in China, the protection and renewal of historical blocks have become significant issues in urban planning. Over recent years, China has achieved notable success in the protection and renewal of historical blocks. However, some areas with slightly lower historical and cultural value have not yet been categorized as legally protected historical areas, and their preservation and renewal have been overlooked. These areas often lack sufficient attention and investment, leading to the gradual disappearance of their historical features and cultural characteristics, posing a challenge to the inheritance of urban historical culture and the protection of urban features.
