Seems like the reasonable position to hold is that china may not be telling the truth, but it's also probably true that they have very low death rates (eg. in line with taiwan/south korea/japan). The parent post did say "broadly accurate", after all.
Taiwan has 20 million people, an island fortress and is a world-leading example of COVID containment policies. China could not have achieved the result they claim to, as the per capita numbers are laughable and they are also not an island fortress.
China contains about 1/8th of the worlds population and massive land borders, the policy response cannot have been as well coordinated as Taiwan's; there has to have been at least one province somewhere that screwed up badly. There will have been large unreported outbreaks.
Find me another country on earth whose numbers look even remotely like this.
