  2. welcome him/her to visit China in due course.

Dear Bob,

As a member of the Sino American cultural exchange program. I am quite delighted to recall the past two weeks when I studied in U.S. Today, I am writing to extends my gratitude for your warm reception.

It is your considerate help that enabled me to enjoy a comfortable and fruitful trip of study. Thus, I am exceedingly grateful to you.

However, I deem that compared with American, China has a more time-honored history and more various cultural customs.

Therefore, it is advisable for you to visit China in due course.

I am looking forward to your favorable reply at your earliest convenience.

Yours sincerely,

   Zheng Wei.
