Dear Mr. Smith,

I am writing to formally submit my resignation from my current position, effective next month. It is with regret that I make this decision, primarily due to personal reasons — I will be relocating to Qingdao to settle down with my family, as it is my hometown.

Reflecting on the five years I have spent working here, I can honestly say it has been a truly rewarding experience. Collaborating with you and the entire team has been a pleasure, and I have gained invaluable knowledge and skills from everyone. I sincerely appreciate your support and guidance, and I apologize for any inconvenience my departure may cause.

Yours faithfully,

Li Ming

尊敬的史密斯先生：

这是一封正式的英语辞职信范文。特此致信，告知您我计划于下个月辞去现有职务，内心深感遗憾。主要原因是个人家庭因素——我将与家人迁回青岛定居，那里是我的故乡。

回顾过去五年在此工作的时光，我由衷地感到这是一段美好而有意义的旅程。与您及各位同事共事，让我受益匪浅，也收获了珍贵的友谊。请接受我最诚挚的感谢，并对无法继续留任深表歉意。

您真挚的，

李明
