Which railway engineering bureau is better now? Is it easy to get in? What are the requirements?

At present, railway units in China generally require junior college or above, and some must have two copies.

In short, think twice before you act ... sometimes it's not necessarily good to go in easily, but it's definitely not easy to stay, and the result will be very bad. ...
