Books are a symbol of students' identity, as well as all those who "restrict freedom" such as schools, teachers and parents. It seems that tearing up and littering can vent students' pent-up anger during their study, but it is undeniable that these students who tear up books must take various exams in order to gain social recognition, because books are the carrier of human knowledge and the ship of human thought. The ancients summed up the value of books with "the book has its own golden house, and the book has its own Yan Ruyu". The history of the development of world civilization for thousands of years proves that all books are banned, burned and destroyed, which are anti-cultural behaviors of ideological imprisonment or ignorance.
