An interesting post from China analyst Dan Wang, who lives in Beijing, on the current state of the city in the throes of response to the coronavirus response and containment:
I see quarantine enforcement. One day in early February, a uniformed municipal employee set up a tent and a table outside my apartment compound, taking the temperatures of everyone leaving and entering. The next day, he gave me a paper slip, saying that I needed to display it every time I came in. It was a good thing that I received that entry card when I did, because I would have to go through a gauntlet of tests to be issued one today. These guards have been the chief enforcers of the quarantines, making sure that those who return from overseas or other provinces have to stay indoors. Given that everyone lives in big apartment compounds, it’s more or less possible to make sure that only approved people are allowed in or out of every residence. From where these enforcers emerged is a mystery. The source of their legal authority to regulate my entry is unclear to me; sometimes the entrance is staffed by volunteers, whom I assume are retired Party members.
