Part-time librarian has a good job. Because the library environment is relatively simple and single, the pressure on librarians will not be great, but the library takes the professional title route, primary, intermediate, secondary and positive. I have to go through years and papers along the way, and passing the title does not mean that I can enjoy this treatment. Only when the library hires you for this position can you enjoy the treatment. Librarians mainly look at cities, and the better the urban economy, the higher the treatment.
