Why is it difficult to get into Zheng Tie?

It is difficult for Zhengzhou Railway Bureau to recruit regular workers. Zhengzhou Railway Bureau mainly recruits fresh graduates of railway major from railway colleges, and the number of graduates in general colleges (higher vocational colleges) is relatively large every year, so it is relatively easy to enter the railway bureau. Undergraduate institutions such as Beijing Jiaotong University, Southwest Jiaotong University, Lanzhou Jiaotong University and East China Jiaotong University also recruit a small number of graduates every year. If you are not fresh graduates of these institutions, it is difficult to enter the railway bureau.
