This paper explores the topic of cognition and Chinese idiom learning, focusing on generalizing typical cultural implications of Chinese "alcohol" idioms and providing suggestions for the teaching of Chinese idioms. This paper is divided into five sections. First, we present a literature review of the most current and relevant materials on this topic. Second, we examine differences between Chinese and Western drinking culture and the cultural implications of Chinese "liquor" idioms. Third, we present the process and design of a study conducted about the differences in cognition of Chinese idioms among learners with or without knowledge of Chinese culture. Eleven American students, with intermediate to advanced Chinese proficiency levels, participated in this experiment. Fourth, we analyze the survey responses and make conclusions based on the results of the study. Finally, we provide suggestions for the teaching of Chinese idioms based on metaphorical mechanisms.
