Before making a phone call, make sure that the call is correct and say: Hello! If the voice is unfamiliar, ask: Is this your home phone number? Then introduce myself: I'm XXX, and I want to find XXX. If the phone number is correct, the other party will definitely tell you that this is XXX's home. Just a moment, please. I'll put XXX on the phone

I once met such a joke. One of A's relatives and friends came to A's house-B, another of A's relatives and friends, C, and called A to inquire about the hotel reservation for the holiday dinner. C calls A's house and B answers the phone. Hello, who are you? (Because B doesn't sound like A), C: Who are you looking for? B: Who are you? C: Who are you looking for? Peng hung up a phone call. A's phone is ringing again, C: Hello, B: Hello, (B recognizes C again), why are you again? Who are you? Who are you? Actually, I didn't recognize the voice of C. If C gives his name, B will know C) C: Who are you looking for? I'm looking for an a. C: You should have said so earlier.
