Abstract: The structure of Bie Ti (You) Duo X (Le) signifies the interlocutor’s subjective evaluation or emphasis on the high degree of emotional intensity, the striking feature of objects, or the high level of activities. Its emergent meaning mechanism is realized through two aspects. One aspect is related to the semantic foundation and licensing conditions, while the other one involves cognitive models and derivational mechanisms. In terms of expressive efficacy, this expression, on one hand, is pragmatically constrained by the subject’s person and the state of events. On the other hand, this structure highlights focal information beyond expectation and enhances the emotional significance of the interlocutor or the information subject.
