What is the most domineering content in a resignation letter?

In this resignation letter, Pu Moumou bluntly stated that he wrote this letter with very complicated emotions, and that he "both loves and hates" his job. First of all, it is his own In the first job, I devoted 11 years of my best youth; secondly, I questioned whether "equal pay for equal work" was a joke and complained that the rewards were not proportional, all because I was a contract worker.

In the letter, Pu confessed that he needed to support his parents and two children, and was forced by life to start a side job in his spare time. He resigned not for money, but for self-development. Later, he said helplessly and domineeringly that he saw what he would look like after retirement in the hospital: 1.8 million in 30 years. This amount can be earned in just two years in one's spare time, so why bother taking 30 years?

“Goodbye my youth!” At the end of his resignation letter, Pu Moumou ended with “feelings.”
