I get where you’re coming from but this type of analysis really pisses me off. The Chinese government isn’t ruled by idiots, and terrorism hasn’t been an issue since decades ago. Even within the country hardly anybody thinks Xinjiang is an ‘unstable region’. Western funded insurgence has been a thing since 50’s tibet, and if trading with the west would lead to it magically collapsing it would’ve happened long ago. China is not a fragile state.
idk bilibili, from what I’ve seen, is more toxic and has a higher concentration of libs. I don’t know about weibo but I’ve heard bad things about it. I’m not too familiar with either, though, so I could be wrong.
