I can tell you what i very very dislike.
I very very dislike the censorship and subsequent propaganda the governing body spits out every time disaster strikes.
Flooding of huge swaths of land? Better post some fake helpers moving one bag of sand with 50 people on douyin.
Tofu Dreg Highrise collapse and people lost their homes? Eh, not my problem. post some fake helpers moving one bag of sand with 50 people on douyin.

96 percent of all citizens earn less than 5 dollars a day? Better spread the big news that we "lifted millions of people out of poverty" everywhere on the internet. Nobody will look up any of the figures and see that people living in the countryside still cannot afford to live normal lives in their home country because they barely make 3 dollars a day.

I can go on.
The worst i hear from the US is that Ohio and Jackson have no clean drinking water.

Ohio because of a train derailment that was directly caused by political incompetence and jackson because of old laws.
But on the US this isnt censored. All news station reported on it. Nobody went to jail for posting tiktoks about it.

The US doesn't send students abroad to intimidate other american students who dare say anything against the republicans.

What?
China isn't communist...

Yeah sure dude, papa CCP aing gonna love ya more just cause ya suck em off.

No, it's just semantics.
China is a dictatorship that call themselves communist. That's it.
