I was going to go home and get married and resign, but I didn't approve it. What should I do?

If you insist on leaving, he won't let you go. You can go to the labor bureau and ask what you should do, because the labor law stipulates that any company must buy five insurances for its workers. And after you write your resignation letter and give it to the company, you can take it with your camera. As long as he won't let you go after 30 days, you can go to the labor bureau.
