University should be the most beautiful and unforgettable time in everyone's life. Most of the things it left us are beautiful, including friendship, without any impurities. Students help each other and make progress together. No economic disputes, no complexity of the world. Everything is so beautiful.
Personally, the impression of the university is unforgettable. I can't find such pure friendship outside the university. A university is like a pure land. Everything is so beautiful and desirable, but it will always come back to the real society, so the university has become my most unforgettable and innocent place.
