This chapter opens with describing communities in Chinese cities, which are explicitly related to residential districts with clear physical boundaries, guarded entrances, community-based governmental and non-governmental organizations, and basic public facilities like stores and parks. Chinese cities are governed via these community grids, in which communities function as micro-drivers behind urban transitions. These communities also enable the implementation of urban, local policies through a high degree of concerted collective awareness and action, which provided essential support during the pandemic for safety, information, food provisioning, healthcare, public space, and facilities. Urban communities acquired a new role in emergency response, risk management, and city resilience during the lockdown period, a trend highly likely to persist.
