According to the theory of cognitive linguistics, the human body experience is the basis of human cognition of the world, the starting point of cognition and the tool of cognition. Feet refers to the lower part of the human body and some animals that touch the ground, and are important weight-bearing organs and movement organs of the human body. Chinese and Korean "foot" words are the core vocabulary in both Chinese and Korean languages. This article mainly studies simple words and compound words composed of Chinese and Korean “foot” morphemes, and divides their semantic image features into two types: “structural meaning” and “functional meaning”. “Structural meaning” refers to the synthesis of “shape, location, and composition”, and “functional meaning” refers to the grammatical functions of the body parts themselves, the semantic functions of human words, and part of speech functions. Through comparative analysis, the similarities and differences between them can be found, in order to provide effective and credible semantic examples and theoretical research basis for teaching Chinese as a foreign language, teaching Korean as a foreign language, Chinese-Korean human lexics, and Chinese-Korean bilingual translation.
