This is really very standard. China operates a huge propaganda network of trolls, bots, you tube accounts, tik tok accounts, etc. They pump out constant propaganda on Ukraine, on the US being beset by drug dealers and addicts, highlighting every catastrophe (the Texas floods as an example), celebrating Iran, Pakistan, etc., while portraying China as an advanced utopia “living in the future!” without crime or poverty.
Of course, 400 million of them still live in mud huts without access to running water or paved roads; 600 million live on less than $135 bucks a month; thousands of them die every rainy season because China has not mastered basic drainage; and all those videos of fancy neon lighted cities are just the same few cities video’d over and over again, and just on the other side of those buildings are the dirty alleys and homeless people they claim they don’t exist.
