From Su Shi's Farewell to Dong in the Northern Song Dynasty. The full text is as follows:
Say goodbye to Dong
He has been wrapped in a big cloth all his life, and his mind is full of poems and books.
Tired of cooking leaves with old Confucianism, it is better to step on Sophora japonica with children.
If it's empty, you can't find a spring horse or see a car.
Proud of the secular, Sun Wong wet words such as crow.
Interpretation: In life, I am wrapped in coarse clothes and poor cloth, and my learning temperament is naturally brilliant. I don't like chatting with the old Confucian about the bitter days of "cooking leaves", so I decided to take the imperial examination with the scholars. If you don't have money in your pocket, you won't buy a "painted face" horse, but you will look at the dazzling "choosing a husband's car". I can also boast to secular people in the exam, and my name is written in crow black on the imperial edict.

"You are full of life, you are full of poems and books." These two sentences were written by Dong Chuan, with thick hair and thick clothes. The word "wrapped in life" is novel and ingenious. It should be "life is wrapped in a big cloth", but once the word order is reversed to "life is wrapped in a big cloth", there is a sense of picture, which means that this life is normal. These two poems praise Dong Chuan for being poor, but diligent in reading, so his spiritual temperament is extraordinary.
This poem is characterized by clever allusions and profound implications. Among them, "humility with poetry and books" is a famous sentence that has been passed down to this day. "Poetry" refers to books here; "Qi" refers to temperament and demeanor; "Hua" means glorious and different.
From the context of praising Dong Chuan in poetry, separately, that is to say, people who are diligent in reading always have a refined atmosphere, which makes them look different. It is precisely because it sums up a common phenomenon among scholars that it has become a famous sentence about reading and learning and is widely quoted.
Ji Xiaolan once commented: Every sentence is healthy. At the end of the two sentences, there is an expectation, and there is a feeling of coldness outside the words, which is not enough for Dong Chuan.
