Dear ,
I would like to convey my heartfelt thanks to you for your kindness to receive me when I participated in an exchange program in USA.
Your generous help made it possible that I had a very pleasant stay and a chance to know
American cultures better. Besides, I think it is an honor for me to make friends with you and I will cherish the goodwill you showed to me wherever I go. I do hope that you will visit China one day, so that I could have the opportunity to repay your kindness and refresh our friendship.
I feel obliged to thank you again.
Sincerely yours,
