How to save paper

1, don't tear the book, one piece of paper, two sides.

2. During festivals, use fewer greeting cards. You can send a message, call or express your congratulations orally.

3. Put a waste paper recycling box at home or in class, collect the waste paper and send it to the waste recycling station or reuse it.

4. Old calendars and waste newspapers can be used or hand-made in Bao Shu.

Books that can't be used are bound into volumes, and then used or made into draft paper.

6. The express delivery industry should minimize carton packaging.
