I only learned it at the age of 28, and now I have been in the business for three years. The salary is 3500. Guangzhou is around 3000. It depends on your skill. Elevator maintenance is very tiring. I work 24 hours a day. It's just nobody cares about you. Eating is not on time either. As soon as the phone calls, you have to leave. I come from Chongqing, and Guangzhou should be higher. I suggest that if you have other doorways, don't learn to repair elevators. I want to give up. I once met a colleague who worked for 20 years and finally gave up. If you have acquaintances to take you, of course, I mean experts, you can still learn. Elevator maintenance also has high salaries, such as technical support. If you sit at home and others can't fix it, you can teach it, and it will be stable for seven or eight thousand a month. That's the real elevator repairman. The average elevator repairman is about 3000. If you want to get into technical support, it's very difficult. The opportunity to see people. I hope you can understand.
