What skills can boys learn after graduating from junior high school, which is better for the future?

Personally, I think if you just graduated from junior high school, It is best to go to another technical school or technical secondary school diploma. Because the school will teach you some basic electrical and mechanical knowledge. This is not taught in junior high school. As for the working environment of CNC machine tools, it will not be very dirty. Because it involves numerical control, the accuracy is not high.

The requirements are relatively high, and dirty will affect the accuracy of the workpiece. But the work intensity is rather tired. Wages vary from place to place, Shantou is about 4000 to 6000 yuan.
