Step-by-step explanation:
In this evidence, we notice that Amy Tan was ashamed of her Chinese heritage. This is evident from the way she describes her father's behavior, which is very different from what she perceives as "normal" behavior. She also mentions the reaction of her guests and Robert, who is most likely a non-Chinese friend. The fact that the minister also burped suggests that it may be a common Chinese custom, but Amy Tan feels embarrassed and silenced by the event.
