感谢信 Dear Tom, I'm writing this letter for the purpose of conveying my sincere gratitude to you for your warm reception while I participated in the exchange program in America
Your generous help made it possible that I had a pleasant stay and a chance to know America culture better
Besides, I consider it 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 would visit China in due course so that I could enjoy the opportunity to repay your kindness and refresh our friendship
Once again, please accept my heartfelt gratitude
Wish you all best
Yours sincerely, Zhang Wei 2
