In addition, it is also related to the salary orientation of enterprises.
For example, if you work as a maintenance electrician in a hotel, the salary will definitely not be very high, generally around 2K, and it is difficult to exceed 3 K. But if you work as an equipment maintenance electrician in a mechanical processing plant, you can get a salary of 3K~5K ~ 5 K ~ 5 K.
If you work as a plumber in a factory, you generally can't get 2K.
