Research on Cross-Cultural Language Use and Emotional Tendencies on Social Media Platforms Based on Big Data Analysis: Taking the Influx of “TikTok Refugees” into Xiaohongshu as an Example

This paper focuses on the highly typical cross-cultural social phenomenon of the large-scale influx of American “TikTok refugees” into the Xiaohongshu platform in early 2025. Using advanced big data analysis techniques, it deeply analyzes the language adaptation and usage status of this group on Xiaohongshu, as well as the dynamic process of their emotional changes. A systematic study is conducted from multiple dimensions, including language use strategies and language adjustments in cross-cultural communication. Combined with theories of language contact and language evolution, it reveals the internal mechanisms of their adaptation to the new language environment. Meanwhile, based on users’ interactive behaviors and performances on the platform, it explores the evolutionary trajectory of their emotions from initial strangeness and curiosity to gradual integration or maintaining distance. The aim is to provide valuable theoretical references and practical guidance for in-depth understanding of user behaviors and emotional change patterns on cross-cultural social media platforms.
