Thank you very much.
A long time ago when I was learning English, I thought about this question, because in both Ancient Chinese and Modern Chinese, we hardly use such a sentence structure. But later when I knew so many native English speakers would say 'my school', I thought it acceptable to say 'my university', because the meaning is clear: the university I am at, but not the university I own.
This discussion reminds me of something. Hermann A. Schumacher was once a professor of political science at Columbia, and in Addresses in Memory of Carl Schurz there is a speech by Hermann A. Schumacher:
An especially interesting illustration of his great captivating influence was once told to me by the curator of my university
If he had owned a university, which is so great an achievement, his biography on the Internet would show this; but I couldn't find anything.
In Chariots of Fire, the winner of four Academy Awards including best picture, there is a famous line:
I am a Cambridge man, first and last. I am an Englishman, first and last. What I have achieved – what I intend to achieve – is for my family, my university, and my country.
