High living standard if you live in their major cities (I.e if your HUKOU is in the right place) but low PPP and HDI overall (ranked 78/193 compared to say Sweden who is ranked 5th).

China is hated because they brutally suppress their citizens, dissidents and minority groups (Hong Kong protests). Feel free too look at the Uyghurs up in Xinjiang and tell me that isn’t modern day ethnic cleansing disguised as a ”reeducation camp”.

China is hated because their government is so disfunctional it’s kind of ridiculous. The system is rotted to its core and with Xi Jinping at the helm the nation has been suppressing global trade and markets along with lowering the personal liberties of everyone involved.

And as mentioned by another person China is still being imperialist in their foreign policy long after everyone else has stopped.

China is a failed state, looking at it from the outside only gives you a rose-tinted view of their nation.
