Update the City of Egrets.

Urban renewal in Xiamen is of great significance to the sustainable development of the city. First, urban renewal helps protect and revitalize historical and cultural areas, which not only preserves the city's historical memory but also injects new vitality into the city. Through renewal, the living environment can be improved, urban functions optimized, and industrial transformation and upgrading promoted, thereby driving the adjustment of urban spatial structure and the restoration of urban ecology. In terms of the revitalization and utilization of historical buildings, Xiamen has adopted a series of measures. For example, through renewal methods such as demolition and reconstruction, preservation and renovation, and historical protection and revitalization, comprehensive and organic renewal is implemented. These measures aim to achieve the protection and revitalization of historical and cultural areas while improving the living environment and optimizing urban functions. In terms of specific implementation strategies, Xiamen emphasizes the importance of protection and inheritance. In historical style areas, the focus is on protection and inheritance, continuing the style, texture, spatial scale, and historical environment of the neighborhood. Under the premise of meeting protection requirements, buildings are maintained, repaired, comprehensively renovated, and functionally optimized, while infrastructure, public service facilities, and the environment are updated and improved. In addition, the Panlong Tiandi project mentioned in the urban renewal design case sharing demonstrates how historical spatial elements such as ancient buildings and bridges in ancient towns can be revitalized and utilized as commercial and leisure spaces, allowing people to experience traditional culture while enjoying the convenience of modern commercial facilities. This combination of protection and revitalization not only preserves historical context but also provides the city with a "living museum" experience, enhancing the vibrancy of the area. In summary, the urban renewal and revitalization of historical buildings in Xiamen not only help protect the city's historical and cultural heritage but also improve the quality of life and economic vitality, achieving sustainable urban development.
