Where is the man’s home?

M: How many places in the world have you lived in?
W: Several. Such as Paris, Rome, New York, and Guangzhou.
M: Did any of them make a special impression on you?
W: Of all the places I’ve lived in, I think I like San Francisco best.
M: Well, of course. You know the saying, "East, west, home is the best."

W: Don’t you think it is harmful? Working all night and sleeping in the daytime?
M: Oh. I’ve stopped that already. Now I’m on three days and off two.
