After putting on a red uniform and a face mask at 8 am, Huang Juan gets ready to conduct a daily quarantine check on 400 households and shops in her community in Nanning, capital of South China's Guangxi Zhuang autonomous region.

For the past few weeks, she has done this each and every day. The necessary routine designed to curb the spread of the novel coronavirus disease, or COVID-19, was so arduous that Huang regularly topped the list for most steps per day on the pedometer app she uses.

Among her everyday items is a "resident roster" she uses to log the health condition of every household. Now, she has memorized most of the information.

Guangxi has more than 80,000 grid-based community workers like Huang.
