“Shuodaotou” is a combination of the verbal verbs “Shuo” and “Daotou”. In the process of modern Chinese language communication, it gradually becomes a typical discourse marker with procedural significance, rather than a predicate complement structure that expresses real meaning. As a discourse marker, it is mainly located between the beginning of the sentence and the sentence, which can connect the words before and after, improve the attention of the listener, express the speaker’s emotions and attitudes, and make the text structure more compact, and improve the coherence and logic of language expression. The reasons for its formation include subjectivity and subjectivization, the participation of metaphors, and the principle of economy, and its evolution reveals the subjectivity and economy of language evolution.
