I said this specific video is peddling conspiracy theory, otherwise they're nothing more than ex-travel bloggers who has recently pivoted to click-bait China bashing after they were pressured out of the country. Yes I was an expat in China in the mid 90s to mid 00s and still have ongoing dealings there.

The point is they are not only not experts in infectious disease, they're not experts in any particular Chinese subjects at all. Living in China is not itself a remarkable qualification. If I were to ask people to find me two youtubers from China who moved to US to do travel blogs that I should base most of my opinions about China on, it would be an impossibly asinine exercise because US is a large, complex country. So is China. That's why you have thousands of institutions and entire industries of specific experts trying to grasp the larger realities. This industry exists for Chinese affairs, yet a surprising amount of people insist on posting generalized, personal reflections of a couple youtubers instead of relevant subject matters for each respective topics which, again exists.
