1. Find a box, put the books in it, and put a label on the outside of the box to indicate the bibliography in the box. Because it is still needed when reviewing the subjects of the senior high school entrance examination.

2. Put it on the bookshelf. When we encounter forgotten knowledge points, we can quickly find and remember them.

3. Donate.

(1) for junior students. Books and notes in books can be reused.

(2) Give it to the security aunt and buy it as waste.

(3) Send it to the school library. It is convenient for our students to get it when they need it.

4. Buy a junkyard. This should be a book that has completed its final mission.
