In response to the COVID-19 epidemic in 2020，Beijing has actively promoted community epidemic prevention and control，committed to cutting off community transmission of the epidemic，so as to lay a foundation for epidemic control. Despite the risk of the spread of the epidemic in Beijing for three times，the timely establishment of epidemic prevention and control mechanisms and the adoption of strong measures by various communities have achieved positive results. Of course，the process of community epidemic prevention and control in Beijing has also exposed some shortcomings，which also need to be made up in time to lay a solid foundation for normal epidemic prevention and control.
