Dear Sir or Madam:
Mr. Wang, the vice-president of our marketing, who has worked for over forty years, will be retiring at the end of March.
Michael, one of our top young managers, will be taking over Mr. Wang's responsibilities from March 20. Michael will do his best to keep the good relationship that you and Mr. Wang have developed over the years.
We shall like to take this chance to thank you for all the support which you have provided us.
Thank your for your information about the retirement of Mr. Wang.
Mr. Wang is our old friend and has provided a lot of support when he is in office. We very much appreciate him because of his superior wisdom and good sense of humor. It is a pity that we will not be able to cooperate with him in the future business. However, we also feel happy that he will be able to enjoy the leisure of his retired life and have more to stay with his family.
We extend our congratulations to Michael for his promotion and we are quite willing to develop a good relation with him as we did with Mr. Wang.
We acknowledge with gratitude receipt of your letter of March 30, 2011, informing us that Mr. Wang will retire and Michael will take over his duty.
We will inform our staffs who are involved in the cases which may be influenced by the handing over and taking over. You can rest assured that our cooperation will carry on and go farther and deeper.
