Dear Li Hua:

It’s long time we haven’t seen each other. I miss you very much. How’s everything going on with you? I am busy preparing for PETS 4.

I would appreciate if you could help me buy PETS 4 English oral textbook which was issued by the Beijing Press, because the books were sold out here.

Drop in when you are free. I often think of those happy days we spent together when we were at University.

Please let me know as soon as possible once you get the book.

My best wishes.

Yours truly,

Wang Lei
