In the context of inventory planning, the urban renewal in China has entered a new stage of quality improvement and multi-governance, while the separation between the old community in colleges and the surrounding community runs counter to it. This paper takes the "hole" in the border fence between the east community of South China University of Technology and the Wushan Garden community in Tianhe district, Guangzhou as the research object. From three dimensions:requirements, management modes and supportive policies, this paper explores the causes of the "hole" and the possibility of opening the "hole" by measuring, tracking, questionnaire and interview. This paper proposes that understanding the management mechanism, building the co-governance platform and setting the stage goals are the ways to promote community co-governance and boundary reconstruction, and to improve the community living circle and realize the resource sharing.
