If you study the technology of machine maintenance and car stopping, there are many differences between the basic theory of the training course and the practical application in the factory. It is recommended to work in the factory for a period of time, and I am sure that I can be promoted if I have the ability. I will sharpen my knife and not miss the woodcutter.
If you have to learn technology, I suggest you go to Huizhou, where the training institutions are mature and convenient to choose.
