I am majoring in electrified railway technology (catenary) in Nanjing Railway Institute. I want to find a job on the railway. How is the railway recruited?

If it is a junior college, entering the railway is a fixed position for workers. Railways are recruited from major railway schools every year, such as Central South University (Changsha Railway Institute) near you. Only the personnel department of the railway bureau has the right to recruit people, and the station has no right to recruit people! You can also enter the Railway Maintenance Management Section of Electrification Bureau, but it is very difficult!
