On May 1st, 58-year-old "elderly person living alone" Wu Xiaowei was found dead from hunger at 502, Building B, 1222 Changle Road, Jing'an District, Shanghai. His body had already started to decompose, and it was another day before it was taken away after being discovered. The community committee knew that, except for 502, Building B, no one in the entire community went downstairs to do the nucleic acid testing, yet they never made any visits. If, during the five rounds of nucleic acid testing, the community committee had at least visited 502 once, perhaps he wouldn't have died.
