Their currency is manipulated.
If you actually knew about the history of RMB and its black market, you would know their manipulation was not effective or at most marginal. And the same practice has been or is being practiced by the US and most other countries.
Their stock market has 2 books, one set you can see, the other you can't.
Same in the US, especially before Great Depression
They sell pet food that poisons pets. They sell baby formula that harms babies.
Many of those "they" got death sentence and executed.
They have no respect for IP property.
Same with the US which stole most of its technologies from Europe in the 19th and early 20th centuries.
They're poisoning their environment such that you can't see across the street due to air pollution, and can't drink the water because of some mining company upstream.
Same happened to the US and are still happening in many other countries. We just exported the pollution.
The news media is censored so that non of their citizens know any of this, except what they can see with their own 2 eyes.
Clearly you have not actually read their online news, likely because you can't even read Chinese and have to rely on your Western media outlets.
