What can a home appliance repairman do without maintenance?

I am also doing maintenance in an electronics factory now, and my salary is only 3000 yuan. I still work overtime every day. I'm tired and I don't want to do it! If you have skills and a little money, don't be too single-minded in selling electrical appliances for repair or selling second-hand air conditioners. In fact, the home appliance repair industry will not be eliminated, and the main cost is low. It depends on how you make money with your own technology! Don't give up easily!
