A poem that describe things strictly.

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

I like to try to find a good poem all my life. The language of the poem is not surprising, and I will not stop.

I pondered these two poems for three years and began to read two lines of tears when I first read them.

Personally, I think diligence is strict.

Lu You's Reading on a Winter Night may meet the requirements.

Read to my son on winter nights.

(Song) Lu You

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.

This poem means that the ancients spared no effort in learning. Fight for it all your life, often when you are young, you will succeed when you are old. The knowledge gained from books is superficial after all, and it is impossible to understand the true meaning of knowledge. To truly understand the profound truth in books, you must practice it yourself.

It is a poem that requires rigorous life and everything needs to be proved by personal practice. It is a rigorous poem.
