As someone who lived in China for many years, I can say that while the people are generally nice (which is true for every country), the government is the definition of evil. The fact that you don't see innocent people thrown in concentration camps because of their race, or people having their organs harvested, etc. doesn't mean it isn't happening. In fact, by living in China you're less likely to understand what's happening because the government aggressively censor anything they disagree with, rewrite history, and silence those who dare to speak up.

What I, as a foreigner, did experience in China was me being denied by 9 out of 10 non-4-5 star hotels, landlords refusing to let me rent there, even call my Chinese friend to inform him that foreigners are not allowed in the building when I borrowed the place during Spring festival. I've also experienced my weixin posts being shadowbanned, I've known two people who got deported (one simply because she refused to sleep with the disgusting visa officer). There's no process of appeal. You can try to go to court but they'll always side with their own, and if your visa gets denied then they are under no obligation to tell you why or for how long. While it's possible to enjoy life in China and live there for many years without issues, one day it will all come crumbling down.. it doesn't matter if you study at the best university, or work for a top company, or have millions invested in the country. The fact that they can so casually kidnap the interpol president, or their most famous movie star, should tell you that normal people, whether foreign or Chinese, doesn't stand a chance, and it's only a matter of time before the social credit system ends up affecting you and other people who choose to live in a bubble.

You did not deny any of these claims about the Chinese state:

1. Government surveillance of domestic citizens is far more intrusive than in any Western country. (NSA revelations are not a refutation).

2. Prominent citizens get disappeared. There is little to no transparency in the judicial process.

3. There is no freedom of speech in China. You cannot criticize the government from within the borders effectively without being in danger.

4. China does not have a free Internet in the sense any Western country does.

5. Social credit scores exist, and will be used to reinforce the government's authority.

6. There are ongoing human rights abuses in China other than what I've already mentioned.

You can evade this all you want and talk about how nobody can possibly know about China unless they go there. But you can't refute any of these, so that is all you can do.
