You should raise your salary before you start working. If you don't mention it at first, it will be difficult to fight for it later. The average apprentice's salary is not high, just enough to eat. Talk it over with your cousin. If the factory belongs to your cousin, that's easy to say. If not, talk to the supervisor about salary. If not, it depends on whether you went through the formal entry formalities at that time. If so, you can go to the labor bureau to handle it.
