Taking international communication as the basic context, this paper focuses on the two theoretical propositions of "why online literature is Chinese story" and "why the Chinese story can be told well". The theoretical model of the ternary ontology structure of online literature, which consists of story layer, media layer and relationship layer, is proposed, among which the story layer shows the storytelling and Chineseness with distinctive Chinese characteristics, while the media layer and the relationship layer show the "intermedium " with the characteristics of cross-media narrative and global digital narrative. The three characteristics give Chinese stones a three-dimensional spiritual connotation, a localized cultural temperament and a globalized open context, thus building a theoretical basis for telling Chinese stories well in online literature from the international communication perspective.
