Final answer:
Amy Tan uses negative imagery in "Fish Cheeks" to express her discomfort with her cultural heritage and the cultural clash she experiences during a family dinner.
Step-by-step explanation:
Amy Tan uses imagery with negative associations in her short story "Fish Cheeks" to convey her feelings of embarrassment and discomfort about her Chinese heritage, especially in the context of American culture. This stark description of the traditional Chinese dishes serves as a literary tool to highlight the cultural clash and Tan's struggle with her identity during a Christmas Eve dinner. By presenting the food in an unappealing light, Tan effectively communicates her sense of alienation and the conflict between her desire to fit in with American society and her family's cultural traditions.
