After I resigned, the company immediately told me not to go to work.

You have to settle your salary on the day of resignation, but many companies don't let you get your salary until the end of the month, on the grounds that the end of the month is the company's payday. I've been in this situation, as long as the company pays you, it doesn't matter. If you don't give it to you, you should be prepared to sue the labor bureau and must defend your labor income.
