This research focuses on the development of several cities in Southern Yangtze of China to investigate the change of the residents in their lifestyle, living attitude during the “demolition’’ and “construction” in the perspective of urban plan and environmental design. Through the experiments of design projects in urban plan and environmental design, solutions would be found for those disharmony problems occurred during the transition process of “demolition” and “construction”. The proposals, from both the tangible and intangible points of view, would be developed for the development of the cities and regroup of residents, as well as the reconstruction of new communities with extension of traditional custom.
