This paper analyzes more than 150 buzzwords from 2010 to 2020. The examples of Chinese catchphrases involved in this study are derived from Chewing Words. These buzzwords and examples are mainly selected from People’s Daily and China Daily. Based on the conceptual metaphor theory and the conceptual hybrid theory, this paper attempts to conduct cognitive research on Chinese metaphorical buzzwords, including their classification, cognitive semantics and functions. On the research method, this paper adopts the combination of diachronic and synchronous research, description and interpretation, and qualitative research. This paper discusses and analyzes the cognitive mechanism, the reason of popularity and the function of metaphorical buzzwords in the process of metaphorical meaning construction. On the one hand, the analysis of these buzzwords provides realistic material for the study of metaphorical buzzwords, and also provides a new perspective for further research. On the other hand, it is expected to enhance people's understanding of some social phenomena and problems behind metaphorical buzzwords, and help to play its active role in spreading light. In the long run, the study of metaphorical catchphrases provides a useful reference for the historical evolution and future development of Chinese catchphrases.

文字是一个时代的缩影，而流行语则是现代语言环境中的重要组成部分。流行语不仅 具有一般词汇的表意功能，而且在一定程度上生动地反映了人们的思想意识。流行语中隐 喻性词汇相当多，这表明隐喻无处不在，隐喻是语言的一个本质特征。在认知隐喻研究阵 营中，人们普遍认为语言是隐喻思维方式最有说服力的体现，而隐喻是语言本身的特征。 因此系统研究流行语的认知角度，不仅具有理论基础，也具有重要的现实意义。本文对20 10年至2020年的150多个流行语进行了分析。本研究涉及的汉语流行语示例来自《咬文嚼 字》。而流行语和例句主要选自人民网和中国日报网。本文旨在基于概念隐喻理论和概念 混合理论对汉语隐喻流行语进行认知研究，包括其分类、认知语义和功能。在研究方法 上，本文采用历时与共时研究相结合、描述与解释相结合、定性研究相结合的方法。分别 探讨和剖析隐喻意义建构过程中的认知机制、流行的原因以及隐喻流行语的功能。通过对 这些流行语的分析，一方面为隐喻流行语的研究提供了具有现实意义的材料和新的视角另 一方面，它有助于人们对隐喻流行语背后的一些社会现象和问题的理解，有助于发挥其积 极的传播光明的作用。从长远来看，隐喻流行语的研究对于汉语流行语的历史演变和未来 发展提供了有益的参考。
