These concepts function in the linguistic space of the world as one of the universal binary oppositions. This is most clearly expressed in constant word combinations and paremies. An attempt was made to determine the differences between the Ukrainian and Chinese language worldviews in situations where these concepts are present. Ukrainian and Chinese fixed word combinations and paremias with the semantically core words left and right // 左 and 右 were chosen as the object of study. The subject of the research is the identification of common and distinctive features in the perception of the Chinese and Ukrainians of the views and habits of using the concepts of «left» and «right» traditional in their national language worldviews. The procedures of semantic, connotative, phraseological, linguocultural, conceptual, cognitive, comparative and quantitative analysis, as well as the descriptive method, were used in the research process. The results of the research were the identification of selected Ukrainian and Chinese phraseological units that contain indicators of the concepts «left» and «right» // 左 [zuǒ] and 右 [yòu], their classification by discursive meaning, sphere of functioning, axiological characteristics, and a comparative analysis of the linguistic and cultural principles of use in the Ukrainian and Chinese languages was carried out. Conclusions are made regarding the asymmetry of the traditional perception and functioning of the conceptual meanings of left and right in compared languages
