Research on the Interactive Elements and Functions of Live Streaming Sales Language ——Take “Hao Bu Hao” as an Example

This paper starts from the expression function of the high-frequency construction “hao bu hao (Ok?)” in live streaming sales. By classifying and analyzing the structure from the perspective of context and multimodal discourse, the paper finally summarizes four interactive functions of the tag question “hao bu hao (Ok?)” in the specific context of live streaming sales, i.e. seeking recognition, holding the turn, maintaining attention and emphasizing the key points. This paper further demonstrates the diachronic subjectification process of tag questions such as “hao bu hao (Ok?)”: the question degree weakens and gradually evolves into discourse marker. The emphasis function can distinguish the key information, which is a supplement to the interaction function of tag questions in previous studies. Besides, it should be noted that several interactive functions of “hao bu hao (Ok?)” are not contradictory, and only one “hao bu hao (Ok?)” is likely to show multiple functions at the same time.
