Now in Beijing, I want to be a maintenance electrician in the property, but only an electrician has no operating license. Can I come in? What about treatment? How high is the salary?

Beijing property electrician's salary is very general, about 3000, which is basically the level of food and clothing. Of course, if the technology is good, the salary is not limited to these. What you said about electricians having a professional qualification certificate is basically useless. The operation certificate is necessary, and so is the network access certificate. Without the latter two, I'm afraid it's hard for you to get an interview.
