Choosing a training mechanism is a wise choice. I just worked as an operator in a factory and didn't have a chance to learn programming, so I went to the SMT training department of Guangdong Polytechnic Normal University to learn it. Not long after reading it, I was introduced by my teacher to a factory in Shenzhen as a heavy machinery technician. School theory and practice teaching for half a day, all machines are open to students. Therefore, if you study hard, you will learn well. Go to school and have a look. It's not far from Dongguan in Tianhe District of Guangzhou.
