These are disproved very fast by the fact that the chinese government doesnt want you to talk about it. Governments dont usually create whole censor campaigns around things that never happened. And before you say us this and us that, the us is also trying to cober things up and we also know a lot of those things because they get leaked. Talking about the us is a classic tankie move because it diverts your attention from the actual thing you were talking about, china. Just move to europe if you can and help in making a place that isnt an absolute shithole because sadly, currently europe is getting really close to that status.
