Abstract:The emergence of "hu弧" and its derivative form "hurenjing弧人精" is the result of grammaticalization driven by category metaphor and the integration of cognitive space concepts. Its popularity reflects the progress of science, technology and culture, the change of interpersonal relationship and the development of education in today's society. The study of neologisms should be more from the perspective of cognitive linguistics, and pay more attention to social cognitive phenomena in the process of research, so as to better reveal social life phenomena, better guide Chinese research and serve the construction of socialism with Chinese characteristics. In memories of Professor G. Fauconnier (1944-2021), a pioneer in cognitive linguistics.
