This is a pretty extensive topic that I remember we discussed on Genzedong quite extensively at the time. I hope someone can give you a good collection of (more serious) sources that you can study, so i will just give my brief opinion:
In short: better than any other country on earth (save perhaps the DPRK), and very close to the what the ideal response should be in cases of pandemics, which can be summed up simply with: putting people before profits.
Not only did they initially correctly prioritize completely containing and eliminating the virus (and were largely successful in doing so until it became clear that unfortunately, most of the rest of the world was unwilling and unable to do the same and preferred letting it become endemic), they also mobilized significant state resources to socially and economically support the people throughout difficult periods.
Contrast with the western (lack of) strategy of porous and ineffective semi-lockdowns extended over long periods of time, with constantly shifting and confused policies, which combined the worst of both worlds: failing to contain the spread while at the same time causing economic damage and social discontent.
China instead opted for brief and localized but disciplined and stringent lockdowns, combined with rigorous tracking of infections so that throughout most of the pandemic most of China remained unaffected and normal economic activity could continue.
They also invested in explaining to the people through proper education and messaging why these measures were necessary, thus generally preventing widespread discontent.
However even they were not perfect, as they eventually allowed Shanghai (which is very capital-brained) to sabotage the entire national strategy.
Also, they did not impose the same rules on Hong Kong, which as a result did far worse than the rest of the country, and you can visibly see that it has struggled to recover and has since been falling further and further behind the mainland (though that is a bigger issue not just tied to the pandemic).
