Abstract: The "urban disease" and its governance in super large urban communities are currently important challenges faced by urban governance in China. As a rare super large urban community in the world, the "Huilongguan-Tiantongyuan Area" in Beijing presents a series of prominent "urban diseases" problems such as excessive population expansion, severe traffic congestion, severe shortage of public service resources, community supporting and block public facilities. It has become one of the most typical challenges in urban governance in Beijing and even in the national urbanization process. Based on the perspective of full cycle management theory, the causes of urban diseases in the "Huilongguan-Tiantongyuan Area" are mainly manifested in the division of urban functional space throughout the entire cycle, leading to "single work" cities and "urban functional islands". The fragmentation of the entire life cycle of citizens leads to the dissolution of the subject; The rupture of the entire cycle of urban culture leads to the elimination of scenes; The tearing apart of the entire cycle of urban governance leads to an imbalance between power and rights. In view of this, attention should be paid to the following policy paths in the renovation of super large urban communities: stitching existing urban functional spaces and constructing a full cycle composite urban functional zone, reestablish the dominant position of citizens and improve the full cycle public life service system for citizens, strengthen scene creation and create a full cycle urban cultural system, adhere to joint construction, governance, and sharing, and give new impetus to urban governance.
