Amy Tan's <em>Two Kinds</em> tells the story of Jing-mei and her life, brought up to be a prodigy of any talent. But the conflict arise from her own want to assert and understand her identity, trying to fit into the American culture while her mother's trying to make her become a <em>"prodigy"</em>.
Old Lady Chong is the mother of Old Chong or Mr. Chong, the piano teacher from the first floor of the apartment building that Jing-mei and her family lives. And she is mentioned just once in the story when Jing-mei went to the piano lesson. She reveals she <em>"met Old Lady Chong once, and that was enough. She had a peculiar smell, like a baby that had done something in its pants"</em>. Thus, the author uses the sense of smell in describing the old lady's age.
In “Two Kinds” by Amy Tan, when the age of Old Lady Chong, the piano teacher's mother, is being describe, the author uses two similes she smells "like a baby that done something in his pants” and has skin "like an old peach" appealing to the smell sense.
