You don't have to arbitrarily trust some authority. Everyone in the country could see from their own experience that spread of the virus really was being effectively controlled.
The question is, do you think it is easier or harder to spot the lies of Western journalism, and what problems does that cause in forming a base to judge others?
No, it's not 'the question' whether it's easier or harder to spot the 'lies' of Western journalism. That has no bearing whatsoever on the obvious, cut and dry reason for the underreporting of covid deaths in China.
But it is worth pointing out that, unlike the "news" propaganda organs of dictatorships, Western journalism is in no sense a monolith that speaks with one voice. Not even mainstream media in the US speaks with one voice (because yes, Fox is the MSM too). So while it may require a bit more sophistication to pick out truths, it is at least not a one-sided distortion of history in favor of the rulers.
No, finding the flaws in western journalism takes more effort because it's not as obvious. Which means the rulers can get away with propoganda and manipulation much more easily than one who provides a direct, complete and obvious propoganda.
I think people would be wise to be equally critical of left and right MSM, not just assume they aren't propoganda because they are on different 'sides' (hint, they're not really)
An ounce of prevention is worth a pound of cure. If you keep the virus out of the country, you don't need great hospitals.
Neither did China. How stunning. It must be due to their fantastic public health systems.
