Dear Robin,
I'm very glad to learn from your letter that you and your sister will come to Beijing and visit me on June 3rd. But I'm terribly sorry that I can't meet you because I have to attend a meeting in Zhuhai. Now let me tell you the way to my house.
When you get out of the airport, you can take Bus 359 to Dongzhimen. Walk across the flyover to the west until you see a bookstore on your right. Turn left there and go straight ahead. Then you can see a bank, and then a cinema on your left. The apartment building I live in is next to the cinema. Find Room 403 and my mother will be meeting you at home.
I'll be back on June 5th.
Best regards to you all.
Yours truly,
Li Ming
指路。
