Many local labor bureaus have vocational training courses such as electrician, and many vocational schools can also learn electrician. It is more convenient to take the electrician's license to go to school, and vocational schools generally face social workers, so the study time and curriculum arrangement are more diversified, with night shifts and weekend classes. You'd better go to the field to consult, and even some schools can listen to the course, so that you can learn more about the course content and the level of lecturers. I don't know the price, but the general mechanical and electrical maintenance is 2000.
