You can actually see a lot of gifs right now on reddit being taken straight from Douyin because that's where cool/fun stuff is being created.
To compare with Vine - by not having time limit, I was able to see the 30sec video of how too cook one of the Chinese dishes, or 1 minute video of a metal welder creating one of his metal sculptures.
It's extremly addictive I think, because content might be realy short or quite-but-not-too long.
I'm trying to say in a roundabout way that Douyin content is miles ahead of TikTok content. I haven't seen too much of the TikTok's girls seeking attention content issue.
