As an aside, I'm finally starting to hear some rumblings of discontent from my Chinese friends here who were very pro-government Covid policy for the last 2 years. It seems to me that the policies that discourage or outright ban returning to their home town for the Spring Festival for a 2nd or 3rd year in a row is getting many people to re-consider the wisdom of this zero Covid. In addition, now that they have started to lock people into shopping malls or their apartments in tier one cities for a few days just for having breathed the same air as a suspected close contact, there is additional pushback against such measures. Maybe things will slowly start changing if the discontent keeps growing.
