Which is better, Wuhan Railway Bureau, Chengdu Railway Bureau or China Railway Construction Electrification Bureau?

I graduated from Dalian Jiaotong University, and now I am majoring in China Railway Construction in Shenyang Railway Bureau. But it is more beneficial for you to go to the railway bureau for development because China Railway Construction or Engineering Bureau has a basic degree in departments, and the major railway bureaus are different. At present, we attach great importance to recruiting undergraduate graduates, that is, cadres can be promoted to engineers after three years of work.
