1 Books are the ladder of human progress.

2 When the book is used, it will be less regrettable.

3 A young man who doesn’t know how to study hard will regret studying late when he is old.

4 Love books, they are the source of knowledge.

5My child! Let books be your good companions, and let bookcases and bookshelves be your happy garden. Bath in their paradise, gather their fruits, pluck their roses, receive their fragrance and fragrance.
