The purpose of this study is to use the hierarchical theory of conceptual metaphor to analyze the cognitive rationale of the lexical meaning of “过来/过去” and “건너오다/건너가다”, and to help Korean learners grasp the basic semantics of “过来/过去” more easily by analyzing their similarities and differences, as well as to provide some insights for teaching Chinese as a foreign language. As a convergent verb, “过来/过去” appears as [V+오다/가다] in the elementary grammar teaching of compound convergent complement. From the observation of Korean Chinese textbooks, we found that the Korean translation of “过来/过去” is different. In fact, there are obvious differences in the spatial concept, i.e., the semantics of displacement, between “过来/过去” and “건너오다/건너가다”. From the analysis, it is clear that it is feasible to construct a metaphorical mapping hierarchical representation of displacement events through the imagery schemas formed in people’s daily experience to help us grasp the similarities and differences of paraphrased words between languages in a more intuitive way. This paper uses the latest theory to investigate and confirm some different conclusions, which are meaningful in a way. The author believes that if the translation of Korean lexical pairs of Chinese convergent verbs can be adjusted to a combination of cognitive-semantic interpretation and image schema in Korean Chinese textbooks, it can at least help to reduce bias.
