The family situation is not good, my father wants to work in other places, but my mother doesn't agree.

How old are you? If you are an adult, you can persuade your mother not to treat your father like this. If she did, others would be beaten. Your father is either reluctant to hit her, or he can't beat her. In this case, I think it's better to let your father go. On the one hand, you can suffer less, on the other hand, you can earn money to support your family. If you are young and don't listen to your mother, you can find that person.
