Dear Professor Morris,

I hope you still remember me. I am Limin, your student in class of Strategic Management in 2019 year. I got an A- in your class and have learned a great deal from your class. You are one of the best and most impressive professors in my entire academic experience in college. 

Now you know I have just graduated and now I work in a major financial institute in Shanghai China. As I found much of the practical knowledge requires much more in-depth studies, I wish to further my studies in graduate school. Therefore, can I ask you to do me a favor to write me a reference letter to support my graduate application? 

I really appreciate your kindness and help. And I know it will be quite a burden on you during your busiest time of the semester end. If you can give me the honor of having you as my recommender, I will provide you with my updated resume and other materials including school list or PS framework to help you write the letter. 

Thanks a lot and look forward to hearing from you soon. 

Best regards, 

Limin Xu
