Also known as tiktok, it is on most of my white-collar workers' phones (we are living in China).

WeChat was the elephant in the room 4 years ago, now with mobile payment in China everywhere, yet almost nothing on HN for a couple of years while it was storming China.

From anecdotal observation Douyin seems to be cutting into the social media thing WeChat did with microblogs, while WeChat micro-blogging has enveloped to limited duration posts and closing viewing to friends/contacts only.

Looks interesting. Duoyin is huge. Surprised HN doesn't have tentacles into interest in this.

If I'm the first tentacle sucker, just ask.
