Who’s Li Ming?

M: Hi, Jane. Where are you going?
W: Hi, Tom. I’m going to the hospital to see Li Ming.
M: I saw him yesterday. He’s much better.
W: That’s good. Must I catch a No. 21 bus to get there?
M: No, you needn’t. A No. 44 bus will also take you to the hospital, and you can catch it more easily.
W: I’ll get a No. 44 then. But where is the bus-stop?
M: Go two blocks ahead. It’s just near the post office,
W: Thank you. Bye, Tom.
