When does the railway generally recruit people from the society?

Railway recruitment is generally internal recruitment, and railway children and graduates of railway professional schools give priority to signing contracts. If you want to go to the railway, you'd better have contacts inside the railway. Except for the Railway Public Security Bureau, the Railway Transport Procuratorate and the Railway Transport Court, which have been separated from the Railway Bureau and turned into national civil servants, all other departments are operating behind closed doors at the end of the year.
