Is there a future in learning hosiery machine maintenance?

There is a future, but pay attention to the fact that the hosiery master is unwilling to teach you. I don't know why, maybe I'm afraid of grabbing a job. If someone really teaches you, this is still no problem. 1 year, you can basically take classes by yourself. After three years, you can go out and pack your own machine. It is still no problem to drive more than 3000.
