Which poem of ancient and modern sages can reflect that reading can broaden one's horizons and increase one's knowledge?

"Ancient and modern sages" said that if you want to know what's going on in the world, you must read the books of ancient and modern times. Good songs are never tired of singing, and good books are never tired of reading. Reading can make you doubt and doubt can teach you. Reading silently is easy to think, reading aloud is easy to remember. Reading a good book for the first time will make you a good friend. Rereading a good book is like knowing an old friend. Pay attention everywhere and learn.
