“Fo Xi” has become popular on the Internet since the end of 2017 and attracted widespread attention. Under the framework of “Fo Xi X”, people create many “Fo Xi” expressions according to different communication contexts, such as “Fo Xi Raising Children”, “Fo Xi Chasing Stars”, “Fo Xi Employees”, etc. It is obvious that the buzzword “Fo Xi X” has significant memetic qualities. At present, domestic researches on “Fo Xi” are mostly carried out from the perspectives of communication, culture, and sociology. Although a small number of scholars have analyzed the formation and dissemination of “Fo Xi” from the perspective of linguistics such as cognition and semantics, there is no scholar who has integrated internal factors such as structural, semantic, and pragmatic features, with external factors such as subjectivity and contextualization to analyze the influence on the generation, reproduction and spread of the linguistic meme “Fo Xi X” based on memetics. From the perspective of memetic theory, this thesis makes a tentative exploration of “Fo Xi X” expression, and provides a relatively comprehensive explanation of the internal and external factors that affect the generation, reproduction and dissemination of this expression, as well as the pragmatic functions that “Fo Xi X” expression realizes in the process of communication, which supplies a reference for the application of memetics to the study of language phenomena and enriches the case study of Internet buzzwords to a certain extent.

In the past, the research on the new “Bei” structure mainly focused on its language form, usage and rhetorical function, but there is still a lack of in-depth discussion on its formation mechanism and development trend. Based on the analysis of media corpus, this paper discusses the characteristics of the new “Bei” structure from the perspective of cognitive pragmatics. We believe that the new “Bei” structure is a deviation from the prototype of “Bei” structure in the idealized cognitive model. Its emergence has its cognitive motivation and pragmatic motivation: language users use this language form to realize the cognitive prominence of some negative behaviors, and express their communicative intention in this economic way. The formation process of this structure is also the pragmaticization of the cognitive ability of language users, but with the increase of frequency, this structure gradually appears the trend of departure and lexical chunking. The results of this study are helpful to deepen our understanding of the new “Bei” structure, and it is also a supplement to the study of “Bei” sentences.
