more "big whites" joining in, the order of life in the community, which was tense at the beginning, soon returned in order.

Under the guidance of the community, the "big whites" have established more than 10 WeChat groups such as nucleic acid groups, nucleic acid code scanning groups, and distribution and maintenance volunteer groups for all members of the community to ensure the timely transmission and communication of various information, and all tasks were allocated and organized appropriately.

The "distributor" wearing "big white" clothes turned out to be a "property security guard". The property administration set up a distribution team composed of six people, who were divided into morning and evening shifts. They put on protective equipment as required to enter the controlled area to undertake the task of delivering express delivery for the residents of the sealed building, and delivered goods immediately to ensure the normal life of the residents.
