I wrote this resignation with a mixed feeling. Because of the confidence you have shown in my ability and personality， my five years in this company have a period with much growth and challenge.

　　But as you probably know， I am also very interested marketing. Now that I got the opportunity， I would like have a try.

　　Thank you sincerely for all the support and encouragement you have provided during the years we worked together.

　　Liu Peng
