I work in a clothing factory, and then the next morning the leader sent me a WeChat telling me not to go to work, saying that I had nothing to do? Okay, so there's nothing to do?

You should go to the factory and ask the situation face to face to see if you really have nothing to do. If this is the case, you can choose to resign and find another job. You can get your salary back. You can rest assured. If the leader deliberately makes things difficult for you and you want to work there, you can explain your specific situation to the leader and he should let you go to work.
