Everything happened so suddenly. Life was normal until the lockdown and we were all caught off guard. At the beginning of the outbreak, the frontline health workers were working intensively from 06:00 to 23:00 and some of them don’t have cars.Public transport has been stopped so sometimes they had to cycle for up to two hours to get to work. It’s very tough in the winter. So people started to set up WeChat [a popular Chinese messaging app] groups to recruit and organise volunteers.
