Dear Jack,

    Next Saturday will my birthday. I'm going to hold a birthday party at home on the evening. It will start at 7:30. Some classmates as good as some foreign friends have been invited. The activities include singing, dancing and sharing interesting experiences. Surely, we'll have a good time. I would feel honoring if you could come. I live at 656 Minzu Street. You can take Bus No. 11 or No. 15 and got off at the stop of Guang Ming High School. Justly on the opposite side is my house, what is red with a white door. I'm sure of you can't miss it. I do hope they will come.

    Best wish.

Yours,

LiHua
