I am now in Shenzhen and have been a taxi driver for 4 or 5 years. I'm tired of it. I wonder if you have any experience? Still tired, want to learn CNC lathe, who can take me,

Tired of it after only four or five years? I work much longer than you. Be persistent, young man, and master this technique first. You are thinking about numerical control, which is more complicated than you think, and you need to use the basic knowledge of ordinary cars. You've only been a regular car for a few years and haven't touched it yet. There will always be disappointment. If you stick to it when you are young, it will be a great asset for you in the future.
