Well, the most serious lie fortunately has the most material that thoroughly proves its falsehood. The following link contains more links to many such resources: https://xinjiangahr.carrd.co/ It's a place to start, both if you want just immediate proof that there is no genocide as well as if you want to learn more about what really has been going on in Xinjiang.

Even though they still are obligated to call it a spy balloon because The Narrative is still officially that it was, even western media have quietly admitted that despite flying across the continent, the balloon did absolutely no spying and actually appeared to be utterly incapable of doing any spying. Weird, how inefficient! And seriously, anyone who has even a passing knowledge of weather balloons or spycraft would have told you this from the beginning, as many did. https://xcancel.com/Reuters/status/1674507379306557462

No, Winnie the Pooh is not banned in China and simply looking around a bit for things that exist in China confirms this. Telling people who live in China that people in the US believe Pooh is banned will result in laughter. This is in China, does it look banned? https://www.shanghaidisneyresort.com/en/attractions/adventures-winnie-pooh/ There was a racist caricature image/meme that along with portraying Xi as Pooh also portrayed Obama as the Tigger character. (I would hope no one here would need explaining why both of those are extremely racist). That specific racist image was officially censored online, but censoring racism is a good thing, and again, Pooh the character, the franchise, or anything else like that, none of it banned. That it was is just another silly lie. Though the whole of reddit (for example) believes the lie because it aligns with the rest of the bullshit they think they know about China which is just straight up false.

China's infamous "Social Credit Score" also isn't real: https://foreignpolicy.com/2018/11/16/chinas-orwellian-social-credit-score-isnt-real/ There is a kind of rating system of businesses that allows people to score them based on how well they are a service to the community they're in, but seeing as most people would recognize that as a good thing, the sinophobic propagandists won't tell you that, but instead fabricate yet another bogus story to paint China as a boogeyman. This one is especially galling because all the scary things they made up with this one actually has a much worse version that is reality in the west. It's such a blatant case of projection it's jokerifying.
