How is it that many Chinese students are schooled in the west, and have access to all these books and thoughts, but then they don't exist when they go back home. There must be some significant cognitive dissonance between the two situations. I don't see how they can keep a lid on this long term.
Because really, consider in how many ways the west does not practice what it preaches. Look at how big corporations abuse capitalism, work against customer rights through lobbying. Look at the whole "right to repair" debate. There is plenty of stuff you can pick out and primarily report on on Chinese news. For example, every time there is even just a small protest of black people somewhere in the US, you can be sure it's on CCTV.
Then consider that most Chinese students going overseas are from the big cities, often from families doing well. There are government programs that sponsor studying abroad for students from rural areas, but they make up for only a small share. So you have students from the big cities, living a modern and happy life. And they get here and see that in some areas of everyday convenience, we've already fallen behind. They see China making progress every day, while the west is stagnating, having a lot of obvious internal and structural problems. They see the most powerful country in the world lead by a crazy orange clown being the main source of entertainment on Twitter. Not the prime example for the pros of a democracy.
And then you show them all the stuff that's censored in China, and how the CCP is evil, and how you got freedom of speech and they don't, and they look at how everything is going well back home and just shrug.
So you might conclude they are just brainwashed and don't realize it, but they pretty much think the same about you. The image of China we get presented in mainstream media is horribly biased as well.
In general you need to realize that most people from most countries are pretty content with how things are going. Even though it's not perfect, it's what you've accepted as being normal, since you grew up with it.
