That is bullshit. If you are refering to Tiananmen Square, then I highly recommend you watch the channel Felipe Durante on YouTube. He’s a Brazilian living in China and he have talked about it several times, and even talks about how his colleagues talk about it.
This idea that China is some sort of dystopian hell where you cannot talk about this stuff is just a western lie.
Hey, I appreciate the disclaimer at the top, it shows you care about this stuff, which is already a pretty good step.
Other comrades already provided you with links about Tiananmen Square. The only other two I can link here are this video debunking the western narrative by Hakim and this article about the Arab league’s conclusion after investigating Xinjiang.
With all that said, I think your conclusion is wrong. You are completely right when you say that media outlets and most of the internet are owned up by a handful of billionaires that control the narrative in their favor, including YouTube. But that doesn’t mean everything produced on these outlets are lies or wrong. On YouTube for example, despite the clear disadvantage, there are communists there subverting the machine to educate people on these issues you are speaking about.
Furthermore, your vision of China comes from these same media outlets you already rightfully criticized. I invite you to rethink what you have been told about China, and any other current socialist countries for that matter, Cuba, Vietnam, Laos and DPRK.
You can lurk or ask around on Lemmygrad if you’re curious and want to learn further about that.
