The other day, on the subway to Lida, I sat on the left side of a girl who studied high school with a laptop computer, on the right side of a boy who read English books full of notes, and on the opposite side of a girl who was doing her homework. Then I began to miss my college days a little. Later, walking in the campus of Lida University, I saw their school motto "beauty, truth, goodness" everywhere. I thought that as a girl, the end we had to pursue was so simple. I also saw them hurrying to catch up with the next class after class, thinking that when we read, we were busy to seek knowledge rather than to make money. I also met warm and friendly Pakistani students who took the initiative to show us the way, and visited their university history museum. Then I really wanted to go back to school when I walked down the wind from the Bishop's teaching building. It was a wonderful feeling that I had a wonderful time when I was studying, even if it was not playing with my classmates, but to overcome some learning difficulties by myself. Question: It's a wonderful feeling to have further delight in knowledge. I used to think that reading ten thousand books is better than traveling ten thousand miles. Now I really understand that even traveling ten thousand miles without reading ten thousand books is only a postman.
