When the book is used, I will regret it less, and after the incident, I will understand the difficulty. It means that if you don't know how to study hard when you are young, you will regret not studying hard when you are old.

Enlightenment We should study diligently and ask questions regularly, so that when we really use the knowledge, we will not rush through books.

Extended information

This is an exhortation couplet. Although the couplet is easy to understand, it contains profound philosophy. If the first couplet exhorts people to "learn more", then the second couplet "You don't know the difficulty until you have experienced it" emphasizes the importance of "doing". It is useless to "learn" without "doing".

Lu You said in "Reading on a Winter Night": "What you learn on paper will eventually make you feel shallow, but you will definitely know that you have to do it" (knowledge obtained from books is not perfect after all) . If you want to understand the truth in depth, you must practice it yourself), which also means the same thing.

This couplet uses clear and easy-to-understand language to organically combine "knowledge" and "action", giving people a profound feeling.

The artistic characteristics of this couplet are that the wording is plain, without elaboration, elegant and popular, and the language is natural but has endless charm. It is deeply inspired by the artistic essence of Meng Haoran's "Spring Dawn". The antitheses in this couplet are also neat and natural, and the meanings are relative. It is particularly profound and appropriate, so it has become a masterpiece among exhortation couplets for thousands of years.
