Not only the epidemic situation office, but also the epidemic situation staff of the public security bureau and the police station will call with private mobile phones to ask whether they have done nucleic acid testing and whether they are isolated at home. Because of the huge workload and too many people checking during the epidemic, the relevant staff not only used the office public telephone, but also used their own mobile phones to make calls, with an average of hundreds of calls per person per day. They are very hard, and they want to cooperate fully when they get a call.
