Social media app TikTok, which is owned by China's ByteDance, will be banned in the United States on Sunday unless a deal comes together to sell it to a U.S. investor or the U.S. Supreme Court intervenes.

Under the law, a TikTok ban would essentially make new downloads on app stores like Apple and Google no longer be possible. While existing users could still access and use the app, they would be unable to update the app, which would likely degrade and stop working over time.

In response to the TikTok ban, many users are flocking to Rednote, the popular Chinese app also known as Xiaohongshu — what’s driving the trend?
