I advise you not to cherish your gold-threaded clothes. I advise you to cherish your youth. When the flowers bloom, they must be broken. It means: "An inch of time is worth an inch of gold, and an inch of gold cannot buy an inch of time."

There is a road to the mountain of books, and diligence is the path, and there is no limit to the sea of ??learning, and hard work is the boat. It means: On the road of reading and learning, there is no shortcut, and there is no smooth sailing. If you want to learn more and broader knowledge from the vast mountain of books and sea of ??learning, "diligence" and "hard work" is essential.

Books are the ladder of human progress. ——Gorky

If a person wants to make progress, he should read more books and study more.
