请用英文帮我写一封信给宿舍办公室，告诉他们我是这学期来香港大学交换的学生，由于学期即将结束，我会在五月初左右搬走，有哪些步骤需要做，并感谢他们在这学期为我提供住宿，让我感受到香港大学的舍趟文化。

Dear Dormitory Office, I am writing to inform you that I am an exchange student at the University of Hong Kong this semester. As the semester is coming to an end, I will be moving out around early May. I would like to inquire about the necessary steps that need to be taken before I leave. I would also like to take this opportunity to express my gratitude for providing me with accommodation during my stay here. Your assistance has made my experience at the University of Hong Kong a memorable one, and I have truly enjoyed being a part of the dormitory culture. Thank you for your attention to this matter, and please let me know if there is anything else I can do to facilitate the move-out process. Sincerely, [Your Name]
