At the beginning of 2020, the outbreak of COVID-19 has made many cities around the world re-examine the health and well-being of citizens, urban planning and construction, emergency governance and sustainable development in a state of crisis, and the topic of urban resilience has also returned to everyone's discussion. In recent years, the population flow and gathering under the wave of urbanization have greatly increased the risk of urban public health security. In the face of sudden public health events such as the novel coronavirus and SARS, a city's response reflects whether its physical space layout is reasonable, management and governance is scientific and effective, and social coordination is flexible. How to make the city have a complete set of implementation plans in response to sudden disasters, have adequate response measures, and can quickly recover vitality after the event, is the focus of urban resilience construction. As we all know, a city is a super system coupled by a number of complex systems. The high-speed development of transportation and the Internet makes the connections within and between systems more extensive and complex. Therefore, the design based on urban resilience should not only pay attention to the operation of urban subsystems, but also pay attention to the interaction and balance among subsystems. The 14th Five-Year Plan clearly states that we should conform to the new concepts and trends of urban development, build resilient cities, and enhance the resilience of urban security. The report of the Party's 20th National Congress once again emphasized the implementation of urban renewal actions, strengthening urban infrastructure construction, and building livable, resilient, and smart cities, which pointed out the direction for the comprehensive construction of resilient cities. Under the impact of rapid urbanization and industrial structure adjustment, China's cities have gradually presented problems such as fragmentation and overlap of urban space, lagging urban infrastructure construction, and hollowing out of urban economy. How to build a "safe city" in the "stay, reform and demolition" and let "toughness" integrate into the "bone marrow" of the city is an important topic at present. This paper first analyzes the challenges faced by urban renewal and resilient city construction in the post-epidemic era, then discusses the core elements of resilient city construction, and finally puts forward specific methods, implementation approaches and strategies for resilient city construction under the state of urban renewal, so as to improve the city's ability to withstand disasters, ensure urban security and stability, and promote urban sustainable development.
