The relationship between e-books and paper books

E-books are popular reading tools now. It can put many books together at the same time, just like your library, and it is easy to carry and can be read anywhere.

Paper books are our traditional books printed on paper. The biggest advantage is the feeling of reading, but it is not suitable for carrying, and you can only carry one book at a time, and you can't pre-store it with you.

E-books have nothing to do with paper books. They are all books, but the carriers are different.
