The theory and experience of urban renewal come from the practical experience summarized in the urban construction and development since the 19th century, and there are relatively many studies on the theory and problems in the urban renewal research. Therefore, most of the research and discussion on the old city reconstruction comes from urban planning and design, and its theory comes from design practice, which is also to better guide the design practice. As a historical practice in the process of urban development, the theories, methods and effects of old city reconstruction have obvious characteristics of The Times, places and society. Therefore, the research on old city reconstruction should combine the comprehensive factors such as specific historical stage, specific social background and regional differences.
