So your point is that things cannot improve when they are bad because no one can voice a contrarian view, but your evidence that things are bad is Shanghai's vice-mayor advocating contrarian views?
My point is that the only way for China to contain Omicron is to increase lockdown measures to the point that many people are dying due to lack of food and healthcare. The alternative is to abandon CovidZero policies completely and go the path of heard immunity. And in China you are not allowed to express those facts, because it means the leaders were wrong to promote CovidZero.
