Metaphor

"Shushan" and "Xuehai" are metaphors for knowledge and learning. "Book mountain" means books (knowledge) like a mountain, and "Xuehai" means knowledge like a sea.

There is no limit to the sea of ??learning, and the boat is hard work, and the mountain of books has roads and diligence as the path

It means: If you want to swim in the boundless ocean of knowledge, be patient, try your best, and work hard A good learning attitude will be a moving ship that can carry you to the other side of success; if you want to successfully reach the top of the towering knowledge mountain, diligence is the only way to the top.

On the road of reading and learning, there is no shortcut, and there is no smooth sailing. If you want to absorb more and broader knowledge from the vast mountain of books and sea of ??learning, "diligence" and "hard work" are two essential and best conditions, indicating that diligence is the main point of learning.
