How to be admitted to China Railway Second Bureau?

Going to the Human Resources Department to apply, the subsidiary of China Railway Second Bureau has to go to the designated technical school to recruit railway professionals every year, which is one of them; Second, China Railway Second Bureau has a special recruitment department in Emei Mountain (other places are unknown). But I advise you to know more about China Railway Second Bureau, which is good for your choice. I am also an employee of China Railway Second Bureau, and I know the details very well.
