When I was in college, my classmates didn't want to sit in the front row at that time, because we couldn't play mobile phones and sleep in the front row, and the teacher especially liked to ask these people in the front row, so many students liked to occupy seats, but they all liked to occupy some seats in the back, so I felt that the first three rows in Tsinghua were full, which reflected the students' special love for this course and their positive learning attitude. It is very uncivilized to occupy seats with books.
I don't know when books are allowed to occupy seats in schools. This is because some students may want to sit in the front row, but they don't want to go, so they want their roommates to put a book on the seat, so that others will know that there is someone in the seat and they won't sit in the front row. And they don't have to go to school to occupy seats, they can just wait for class. Slowly, many people will use books to occupy seats, I think. Many universities have such uncivilized behavior and should be improved.
When I was in college, we also occupied seats with books. For example, my roommate, because several other roommates don't want to get up, but if everyone goes late, there will be no good seats, so one roommate takes a seat. In this case, my roommate helps six other people to occupy seats every day. To others, he obviously came early, but he didn't have a seat.
In short, with the development of society, many people have been admitted to universities, and people can gain better knowledge in universities. I think Tsinghua University's courses have been warmly welcomed by students, so people began to occupy seats before 8 o'clock, but I think the behavior of occupying seats with books is very uncivilized and not the behavior of a qualified college student, so everyone should improve this behavior. For college students, it is worth encouraging to actively love learning.
