Paper was invented by a chinese man whose name is CaiLun in East Han dynasty.At first paper was made of fishnet and bark while made of trees now.
How to make a good use of paper?You should not put any paper into a ashcan until it can't be used anymore.
You should collect the useless papers and send them to the recycle bin,and it can renewed by the paper factory.
