Metadiscourse plays a crucial role in text analysis,influencing readers'comprehension and acceptance of the text.This study focuses on informational-persuasive texts about Chinese Pu'er tea,utilizing a self-constructed corpus and combining quantitative and qualitative analysis.By adopting Hyland's interactional metadiscourse model,it explores how merchants use metadiscourse markers to per-suade consumers to purchase products.The study finds that all five types of interactional metadiscourse markers are employed in the infor-mational-persuasive texts and effectively serve their persuasive function,though their frequencies vary.The use of boosters is the most fre-quent,followed by attitude markers and engagement markers,while hedges are used less frequently and self-mentions the least.This re-search not only enhances the understanding of the effectiveness of informational-persuasive texts but also provides a new perspective for promoting Chinese traditional culture.
