[speaker001:] Good morning. May I help you?
[speaker002:] Good morning, I have an appointment with Mr. Wang Li.
[speaker001:] He's not in, I'm afraid.
[speaker002:] But Could you tell me when he will be back?
[speaker001:] I am sorry, I don't know.
[speaker002:] well, do you think I could leave a message for him?
[speaker001:] Certainly.
