Xiaohongshu, widely known outside China as REDnote, is a Chinese social and shopping platform where users share lifestyle posts, reviews and short videos. It drew a surge of international attention in early 2025, when many English-speaking users joined and posted about learning the app, its trends and its community. Short audio clips using its name spread alongside those posts, becoming a quick shorthand in memes and edits for the platform itself, even for viewers who had never opened it.
