The ancients learned nothing, and it takes time to grow old.

What you get on paper is so shallow that you never know what you have to do.

Translation:

The ancients spared no effort to learn knowledge and struggled for it all their lives. They often began to work hard when they were young and achieved something when they were old. After all, the knowledge gained from books is superficial and it is impossible to understand the true meaning of knowledge. To truly understand the profound truth in books, you must practice it yourself in order to learn successfully.

Extended data:

Reading on a Winter Night, a Noble Son, is a godchild poem written by Lu You at the end of the fifth year of Qingyuan (A.D. 1 199). The poet talked about his views on knowledge acquisition from two aspects: one is to spend effort, and the other is to "practice".

The ideas expressed in the poem are not only the experience of reading on a winter night, but also the summary of the poet's diligent study. The knowledge gained from books is simple after all. If you want to know the essence or truth of things, you have to use your own personal practice to explore and discover.

It emphasizes the importance of putting energy into study. It is important to study knowledge tirelessly and persistently, but it is not enough, because it is only book knowledge and a summary of previous practical experience. It is not an armchair strategist, but "hands-on".

Baidu Encyclopedia has a shallow understanding of papers and doesn't know how to do it.
