Answer:
Amy Tan points out the irony in Jing-mei's mother's efforts to get her to become a prodigy: "I soon found out why Old Chong had retired from teaching piano. He was deaf."
Step-by-step explanation:
There are several meanings of irony.
Irony can be the use of words to express a meaning that is the opposite of the literal meaning. For example, if there is a storm going on outside, someone can ironically say: It's such nice weather today!
Irony also refers to the situation the outcome of which is the opposite of what someone would expect. This is called situational irony. That is the case we have here. A piano teacher has gone deaf. That is something you would never expect to happen to someone who plays the piano.
