I have been on Douyin a lot, there is a lot chat rooms for people to debate politics, so it is a 50/50 divide for opinions (for and against). Many of them will say 'China sucks, and US rules'. People learn a way to speak avoiding keywords, if you are not careful, you get kicked out of the chat. Many of them you can tell are against the government, but these are not ordinary people, they probably don't work, and spending most of their time online talking about politics.
