Dear Susan,

I am very glad to hear you are coming to visit me the next Friday. Unfortunate, I won’t be able to meet you at the airport since I have classes in afternoon. You won’t find difficult to get to the city center. The airport bus leaves every 30 minute and will take you rightly to the Friendship Hotel. My class will be over by then or I will pick you up there. I will take you together to a hot-pot restaurant for dinner and we’ll talk with our plan for the weekend over dinner. Having a pleasant trip and see you Friday.

Yours,

Zhang Ming
