How about working as a property electrician in Guangzhou Poly Tian Yue Garden? There is a future, can you learn technology? Because I am mechatronics.

Property electricians are mainly lighting and power distribution. Professional companies are mainly responsible for data communication, elevators and monitoring. Property electricians are usually also responsible for water supply maintenance, called plumbers. It's hard to find a job now, so it seems that you can consider riding a donkey and watching a horse while preparing for research. Pay attention to everything related to electricians at work. If you want to learn, you can always learn something. Read more books, ask more questions and turn over more books. Elevator maintenance seems relatively high, hehe, I hope I can help you. Good luck!
