Top doctor warns the worst of Covid pandemic is unfolding now

That headline alone screams fear mongering and profit motive. What's happening in China has nothing to do with covid, on the face of it anyway, or maybe it does as you point out as they may know something the rest of the world doesn't, which has always been a possibility I've considered.

But I think the more likely scenario is that China is prepping its population for martial law. Yes, it could be something else, something related to covid that they have kept hidden. But I don't think so. They're conditioning the population. It's all very Pavlovian.
