Analysis
In China, 哪里(nălĭ) is used not just for asking directions, but also as a way of being modest when someone offers you a compliment. The use of 哪里哪里(nălĭ nălĭ) here is a way of deflecting the compliment as if by saying, "wher? I don't know what you're talking about." The punch line, then, comes from A's literal response to the question: "Your eyebrows, your eyes…everywher (on you) is beautiful."
