No, they haven't. China got hit just as hard in the 2008 recession as most western countries, and they've been robbing Peter to pay Paul ever since. Eventually Peter gets his due, and China will suffer a serious economic setback. You're starting to see signs of that now. China right now is Japan in the early 1990s. Everything from the inverted population pyramid to the looming debt crisis points to the next decade being very flat for China, and their wolf warrior diplomacy hasn't made them the kind of friends that could help pull them out of it.
That's not to say that western capitalist markets couldn't stand to be significantly more regulated, because they absolutely desperately need more regulation around safety, negative externalities, and anticompetitive behavior. But claiming that China hasn't experienced recession is preposterous. They're too economically coupled with western economies to not suffer alike as recessions hit.
After the 2008 financial crisis, the Chinese government and state-owned banks pumped something like a trillion dollars into the economy, cushioning the impact of the recession. That was one thing they actually got right.
On the other hand you have Great Chinese Famine, Tiananmen Square massacre and more recently Uyghurs concentration camps and most likely genocide and that's only China.
You mean the Last Chinese Famine? The famine that took place in a country with a multimillennial history of devastating rice famines? The famine that was less bad than other, contemporaneous famines in capitalist countries? The famine that marked the last instance of food insecurity for about half a billion people?
The whole thing is bullshit. The famine was sixty years and like four major government upheavals ago. Tianmenen square is the most overhyped government repression in history, and it's never mentioned that many of the casualties were unarmed PLA soldiers burned alive, and the insurgents that attacked them when armed PLA units were able to respond. And of course while there were human rights violations in Xinjiang, they are absolutely not the human rights violations people think they were, and the whole thing was part of a campaign to suppress insurgent groups and needs to be compared to the West's "bomb weddings and ambulances" strategy, to say nothing of the genocidal campaign in Yemen that recently concluded. It's all ignorance, totally unselfconscious indoctrination, and general bs.
https://en.wikipedia.org/wiki/1989_Tiananmen_Square_protests_and_massacre#Death_toll - I would like to point out that as much as they try to obfuscate it even the wiki admits that ~300 is the only credible number, and most of that was street fighting when insurgents attacked PLA troops with molotovs and firearms, with the death toll including unarmed PLA troops burned alive in their trucks
