Dear Friends, 　　　I am writing this letter to thank you for you warm hospitality accorded to me during my recent visit to Beijing. I would also like to thank you for your interesting discussion with me which I have found very informative and useful. 　　　During the entire visit, I was overwhelmed by the enthusiasm expressed by you. I sincerely hope we could have more exchanges. 　　　I am looking forward to your early visit to my hometown when I will be able to pay back some of the hospitality I received during my memorable stay in beautiful Beijing. With kind personal regards,　　　　　　　　　　　　　　　　　　　　　　　　　　　　　Faithfully yours,
