Is there a future for property electrician? At the age of 30, I entered the machine to repair electricity.

Far from promising. It's just that society is like this now. We are all looking for electricians from property companies, even from factories, and we no longer recruit electricians. When something goes wrong, we all ask people from the property management company to fix it. This is the case in our factory. I don't keep electricians and plumbers myself. If anything happens, I'll call someone from the property management company to fix it, and then I'll settle the expenses. It will save money and worry than raising it yourself.
