20 13 undergraduate majoring in electrical engineering and automation in railway colleges. How about going to work in Dongguan subway now?

Only from the perspective of career development, it is still possible. Now it is in the preparatory stage. If the company gives you the position of operation, you should focus on training in the past two years, work easily and have enough time for you to learn professional skills. If the company lets you participate in construction management, the future development space will be broader. The subway is almost a quasi-institution, and the sooner you get involved, the better. Of course, the salary income must satisfy you.
