I lived through this (I live in Wuhan). The scale of the logistical operation to keep a city of 11 million people alive during a two-month lockdown is mind-boggling. And yet on top of that not only did they manage to do this for us, they also built two purpose-made hospitals in a matter of days: Huoshenshan (1000 beds, Jan23-Feb02) and Leishenshan (1500 beds, Jan25-Feb06) not to mention sixteen further treatment centres around the city.

You want jaw-dropping? Here's time lapse of (I think) Huoshenshan being constructed over ten days: https://www.youtube.com/watch?v=jJUaq6XhdLs
