In response to the impending TikTok ban, which will restrict access to the app in the U.S., Duolingo reports a remarkable 216% increase in users learning Mandarin. This trend coincides with the migration of TikTok users to the Chinese social app RedNote, fueling a cultural exchange and a demand for Mandarin language skills. Despite initial challenges with RedNote, many users are eager to embrace this new platform. Duolingo's downloads have surged by 36%, indicating a significant shift in language learning preferences as users adapt to new social media landscapes.
