Well, not sure if a 0 case policy is something that can be maintained at all, lockdown or not. The bigger issue is it's causing issues in the Chinese economic system as well as social structure. People have been locked in their homes, distributed little amounts of food, and children being taken from their families (because they are infected) and taken to lengthy hospital stays. Some of those things are changing, but this is a completely ridiculous, however, expected behavior by the Chinese government. The common people are struggling since the pandemic started and this seems to be the last nail in some of their caskets.
