In this paper, the main research question is How can the Dynamic Protection approach be used for the renewal of the historic residential block and make the old living areas become full of vitality? The historic residential block is a part of historic district, and it mainly refers to the block in which the buildings have mainly the residential function in the past, and even today they still retain the living function as its main function. The community, historical significance, size and built density, distinguishable features and identity, continuity, strong vitality, and diversity are the main characteristics of the historic residential block. the use value is the basic value of historic residential block, and together with the historic value and cultural value, make up very important features of the historic residential block, that should be carefully considered during the renovation process. I argue here that by the dynamic protection approach, the attractiveness and vitality lacking in many of these neighborhoods could be brought into the historic residential block again. The dynamic protection approach emphasizes the sustainable, organic and small-scaled renovation of historic residential block and it focuses on the protection of the intangible cultural heritages as well as the tangible heritages in the block. The goal of dynamic protection approach is to stimulate the development potential of the block itself and restore the vitality to the block, make the block not only well protected, but also re-adapted to the development of the modern city. Therefore, I consider that the dynamic protection approach is suitable for the renovation of historic residential block. In order to explore the application of the dynamic protection in practice, I use a case study approach as my research method. In order to explore the application of dynamic protection approach in a Chinese historic residential block, I conducted a design proposal of the historic residential block in Xijindu historic district, Zhenjiang, my case study, as an application case. I concluded through my case study and the design proposal that the dynamic protection has strong operational value in practice.
