Hello, mainly look at the following aspects. First of all, where do you study? It's much faster to study in a repair shop or school. 2 1 13 school, about two months is enough, because the teacher will teach you alone, but it's much slower in a repair shop, because the apprentice teaches and the master starved to death, so most teachers in the repair shop won't teach you attentively. Second, There is a way to learn sheet metal. Whether the master is willing to teach you skills is related to whether he will teach you systematically. Hope to adopt thank you!
