Riveting and measuring, which job is promising? Please introduce the next two tasks in detail! thank you

Personally, I suggest measuring it. First of all, from the perspective of income, even if your riveting skills are good, it is impossible to earn 5,000 yuan a month, but the starting point of measurement is 5,000 yuan. Second, from the perspective of labor intensity, riveters are iron tailors. Do you know what this means? Just combine some steel plates or something to meet the needs of the drawings. I can't blame you for being tired. The labor intensity is as good as that of porters. The third surveyor is also a technician on site. The only advantage of the fourth riveter is that it does not flow, that is, it is done in the factory, while the mobility of surveyors is large, depending on the project. It is possible that this project will be in the south and the next project will be done in the north, so we should be mentally prepared.
