Core Viewpoint - Shanxi province is home to 28,027 immovable ancient buildings, forming the most complete ancient architectural system in China, with over 94% of lesser-known buildings located in rural areas, highlighting the need for their protection and preservation [1][2]. Group 1: Challenges in Protection - Lesser-known ancient buildings face numerous challenges in protection, including scattered distribution, complex property rights, and a lack of resources such as funding, personnel, and technical expertise [1]. - The protection of these buildings is often reliant on local government and community involvement, which can be inconsistent and under-resourced [2]. Group 2: Community Involvement and Responsibility - A five-level responsibility system has been established in Shanxi, assigning specific caretakers for each ancient building, ensuring that every site has a dedicated "guardian" [2]. - Local community members, often familiar with the area, conduct regular inspections of ancient buildings, reporting any issues promptly, which enhances the protection efforts [2]. Group 3: Social Participation and Funding - Since the implementation of the "Civilization Guardian Project," 473 cultural heritage sites have been adopted by social entities, attracting over 540 million yuan in funding, demonstrating a successful model of public-private partnership in heritage protection [2]. - This model not only alleviates financial burdens on the government but also fosters a sense of collective responsibility among the public for cultural heritage preservation [2]. Group 4: Technological Integration in Protection - Shanxi has initiated a digital protection project for ancient architectural murals, allocating 20 million yuan annually for data collection to support restoration efforts [3]. - The shift from reactive to proactive protection measures, including disaster warning systems and research on damage mechanisms, has significantly improved the preservation rates of ancient wooden structures [3]. Group 5: Effective Preservation Strategies - The preservation of the "Little Western Heaven" temple exemplifies the successful integration of traditional repair techniques with modern protection concepts, emphasizing the importance of regular maintenance over emergency repairs [3]. - Shanxi's approach to ancient building protection demonstrates that tailored strategies, community involvement, and technological advancements can effectively safeguard cultural heritage [3].
