For those of you who have an iPhone, a handy feature that helps with phone lighting at night is "Reduce White Point" in accessibility features. It is different than night mode and reducing luminosity to the minimim and I find it's a nice addition. You can put it in the control center for fast enable/disable should you need it. I have trouble sleeping and I found this helped, albeit marginally.
It seems unlikely that "weakening the west with lots of people unable to participate in the economy" is the goal here, since the zero-covid policy also does exactly that, both short term and long term by weakening the economy and mental health of residents.
