In the days leading up to a proposed US government ban on the social media platform TikTok, American users have turned to another Chinese-owned app, Xiaohongshu.

With a TikTok ban set to go into effect in the U.S. on Sunday, social media users in the U.S. are migrating to Xiaohongshu, also known as ‘REDnote.’

TikTok refugees flocked to Chinese platform Xiaohongshu on Monday, where users greeted them with offers of Mandarin lessons and jokes about spying.
