I see we are still all entrenched in our positions. It could be fun to have a look at the following:

This is interesting: rather than China developing/creating/releasing Covid19, they may actually have been one of the very last countries to be infected. It would appear, according to the article, that the USA had its first infections in 2015. China's big mistake was to actually isolate and identify it -because of SARS they are somewhat more motivated to look for new, novel viruses.
The number of infections or deaths may therefore be related to how early the virus arrived in the country, rather than which lockdown policy or double mask theory is followed. I know some people like to blame whichever politician is deemed to be of the wrong shape, color or variety, but maths tends to trump politics, mostly.
This may also back up the theory:
