"Ningbo South Section" refers to which railway section of Ningbo Railway Bureau?

Nanning Railway Bureau, Nanning Passenger Transport Section. As for why it is not Ning Bureau Ning Section, it is very simple. Nanning Passenger Transport Section was referred to as the Southern Section at that time. How could it be shortened by the last word~~ That is to ask, Why isn't it the southern section of the South Bureau? It’s also very simple. The Nanning Railway Bureau was just moved to the Liuzhou Railway Bureau. Before he changed his name, he had already moved to Nanchang Railway Bureau, which is referred to as the Southern Bureau. There is no other way. There can’t be two Southern Bureaus. So, come first and then arrive. Of course it's Ningju·

And of course it says Ningju South Section on the car, haha! I just graduated this year and was assigned to the Nanning Railway Bureau ·
