I've been using TikTok on and off for the past six months, at first because I was interested in seeing what you can find on the site.

It's mostly teenager dancing stuff, yes. If you start liking political content you'll get political content too. I've found there's a lot of pro-China, both soft-power "look how pretty the countryside is" stuff and straight up Uyghur denial. There's also a decent amount of anti-China activism on there as well, though.
