my general impression is that the greatest concern for china is people getting riled up about anything, and that leading to civil unrest. like what's happening in indonesia right now for example. therefore any kind of content that could get people upset is restricted. so effectively this means no doomscrolling. wechat has something that works like tiktok, and the content there is all positive, uplifting, educational or entertaining. probably just a addictive, mind you, but never once i have seen something that i would want to keep away from my kids.
