How can I enter Shenyang Shanghai GM (Beisheng) or Shenyang Locomotive and Rolling Stock Factory? I graduated from technical secondary school in 2009, majoring in mechanical engineering, seeking expert advice! Thank you very much. .... Are the two companies you chose unrelated?

What I know: Beisheng is mainly a graduate of automobile-related schools. Locomotive and rolling stock factories are even more difficult, mainly designated schools.

Beisheng recruits externally, but the locomotive and rolling stock factory does not recruit externally.

Technical secondary school education is treated as a worker in both enterprises.
