As the threat of a TikTok ban looms, some U.S. TikTok users are flocking to Chinese social media app Xiaohongshu – making it the top downloaded app in the U.S.

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

Chinese social apps Xiaohongshu and Lemon8 have soared to the top two spots on Apple's iPhone charts ahead of the U.S.'s impending TikTok ban.
