Resignation example (sincere version)

Dear Director Z:
Hello!
In the past four years, I have found that I still have a lot of knowledge in my work and life. I can't adapt to the needs of social development. I am eager to go back to campus and continue my studies. After careful consideration, I hereby apply: I voluntarily apply to resign from all positions at XXX, please approve.
In the nearly four years of XXX, I was fortunate enough to receive the guidance and enthusiasm of the leaders and colleagues of the unit. At work, I have learned a lot of valuable scientific research experience and practical skills, and have a general understanding of scientific research. In life, I get the care and help of leaders and colleagues at all levels; I have the guidance and help of leaders and colleagues in my mind, and I have a more mature and profound outlook on life. This nearly four years of work experience will be my first valuable asset in my future work.
Here, I would like to thank Director YYY A, Director B and Director C for their support and help in the past work and life. Special thanks to Director XXX Z for his care and guidance during the past two years and for his trust in me and my guidance on the road to life. Thanks to all the colleagues who have helped me.
I hope that the leader will approve my application and please assist with the relevant separation procedures. I will continue to do my current job well before I officially leave.
I wish you good health and a happy career. And I wish YYY, XXX career flourish.
