On the road of studying, there is no shortcut, and there is no boat in sail before the wind. If you want to learn more and more knowledge in the mountains of books and knowledge, "diligence" and "assiduousness" are two essential and best conditions, so diligence is the key point of learning.
This sentence comes from Han Yu, a famous writer and the first of the eight masters in Tang and Song Dynasties. This sentence is included in "Glory and Contribution", which is a famous saying of his scholarship. It aims to encourage people to study more without fear of difficulties, and only hard work can lead to success.
Extended data:
"Learning the sea" means "learning the mountains", "boundless" means "endless" and "working hard for the boat" means "diligence". No matter in rhyme, part of speech, connotation and artistic conception, every word is steady and appropriate everywhere. This should be the truth of this connection.
Some people may not understand it at the moment. Since there is no limit to learning the sea, how can we say that there is thousands of books Mountain? In fact, although they are related, they are not the same concept and cannot be confused. There is no end to learning the sea, which stems from Zhuangzi's "knowledge is endless", and there is no end to learning and research.
As far as Shushan is concerned, it is objective and practical. As a material form, books always have their limits. Don't say that it is not difficult for ancient people to read four books, five classics, hundreds of books, historical masterpieces and poems and songs. Even in today's voluminous writings, you can use several computers and a pile of CDs to cover all the books of any large library in the world.
Therefore, "the mountain of books is boundless" and "the sea of learning is boundless" embodies a dialectical unity of things.
