How to write an ancient poem about boating in the vast sea?

This is a couplet, not an ancient poem.

Han Yu, a famous poet and philosopher in the Tang Dynasty in China, famously said: "There is a road battle in Shushan, and there is no limit to learning the sea, so it is difficult to sail." This sentence is intended to tell people that there are no shortcuts and no boats sailing with the wind on the road to study. If you want to learn more and more knowledge in the mountains of books and knowledge, "diligence" and "concentration" are two indispensable and the best conditions.
