What poem can I fill in the original sentence in "Preface to Farewell to Ma Sheng Dong Yang"?

Yu liked studying very much when he was young. Because my family is poor, I can't get books to read. I often borrow money from the library, copy it myself, and send it back on the appointed day.

2, it's cold, the inkstone is hard, and the fingers can't bend and stretch, which is very awkward.

3, both crown, and admire the sage's way, but also suffer from no inkstone teacher, celebrities, taste a hundred miles away, ask the hometown first.

If you have played enough in it, you don't know if your mouth is inhuman.

The preface to seeing Ma Sheng off to Dongyang reads as follows:

"Preface to Send Dongyang Ma Sheng" [Ming] Song Lian?

I liked studying when I was young. Because my family is poor, I can't get books to read. I often borrow money from the library, copy it myself, and send it back on the appointed day. When the weather is cold, the water in the salt pond freezes into ice and I can't stretch my fingers. I still don't relax reading. After copying, please go back to China, and dare not exceed the agreed time limit slightly. So most people will lend me books so that I can read all kinds of books. Not only does it benefit the sage, but it also suffers from the lack of inkstone masters, celebrities and tourists. Taste a hundred miles away and ask about your hometown. Senior honorary person, Yemeni students crowded his room, and his words and attitude were never slightly euphemistic. Around Lishi, he assisted the suspect and leaned over to ask questions; Or the more respectful and polite you are when you meet, you dare not say a word; Please ask again as soon as it is happy. So I was stupid and finally learned a lot.

When I was looking for my master, I was walking in the mountains of Otani with my book box on my back and Tara shoes on. In winter, the wind was cold and the snow was several feet deep, and my feet and skin were frozen and cracked. When I got to the house, my limbs were stiff and I couldn't move. People drank soup and covered it for a long time. If you stay with your host, you will eat it again every day, and it will not taste fresh and fat. All the students are embroidered, wearing a hat decorated with pearls and jewels, with a circle of white jade around their waist, a sword on the left and a stinking one on the right, which looks like a god; I am wearing a robe, but I am not sentimental at all. Because there are enough things in your heart to make you happy, don't feel that the enjoyment of food is not as good as others. My efforts and efforts are probably like this. Although I am old and have no achievements, I am fortunate to be among the gentlemen. However, I have been blessed by the son of heaven. After I became a public official, I worked as a consultant every day, and the whole world misreported my last name. What else?

Now all the students are studying in imperial academy, and the county officials have a little support every day. Their parents have Qiu Ge's legacy at the age of 20, and there is no danger of being frozen and embarrassed. Sit downstairs and recite, without running; Some are teachers, some are teachers, some don't ask, don't tell, and some ask but don't; All the books should be kept here. There is no need to record them through other people's hands and read them later. If they are not proficient in their studies and their moral character is not cultivated, if they have no talent and qualifications, they will not be as single-minded as I am. Can you say it's someone else's fault?

Dongyang Ma studied in imperial academy for two years, and his peers praised his virtue. I went to the capital to appear before the emperor, who met me as a fellow villager and wrote a long letter as a gift. The words were fluent and accessible, and I argued with him with a gentle and polite attitude. He said that when he was young, he studied very hard and was a good learner. He was going home to visit his parents, and I told him about the difficulties in his studies. It is said that Yu Mian's fellow villagers are all scholars, and so is Yu. Those who despise me, brag about my wealth and prosperity, and be arrogant to my hometown know the rest!

The translation is as follows:

I liked studying when I was young. Because my family is poor, I can't afford to buy books. I often borrow books from book collectors, copy them myself and return them on an agreed date. When the weather is very cold, the water in the inkstone pool is frozen into hard ice, and the fingers can't bend and stretch, and they still don't slack off. Return it to others as soon as possible after copying, and dare not exceed the agreed time limit slightly. So most people are willing to lend me books, so I can read a lot of books. As an adult, I admire the theory of sages more and more, but I am worried that I will not be able to make knowledgeable teachers and celebrity friends. I ran hundreds of miles away with the scriptures in my hand and asked the villagers for advice. His predecessors were noble and famous, and his master students crowded his room. His words and attitude have never been euphemistic. I stood beside him, asking questions, asking truth, and bowed my head to him for advice; Sometimes I am reprimanded, my expression is more respectful, my manners are more thoughtful, and I dare not answer a word; Ask him when he is happy. So although I was stupid, I finally learned a lot.

When I was looking for a teacher, I carried a book box and dragged my shoes in the old valley in the mountains. In the severe winter, the wind was cold and the snow was several feet deep, and my feet and skin were frozen and cracked. When I arrived at the school house, my limbs were frozen and I couldn't move. The servant poured me hot water and covered me with a quilt. It took a long time to warm up. Living in the hotel owner's place, eating two meals a day, there is no fresh, fat and delicious enjoyment. Students' scholars are all well-dressed, wearing hats decorated with pearls and treasures, with white jade rings hanging around their waists, knives on the left and sachets on the right, which are as bright as gods; I am wearing a shabby robe among them, and I am not jealous. Because there are enough things in my heart to make me happy, I don't feel that the enjoyment of food and clothing is inferior to others. This is my hard work and hardship. Although I am old now, I have achieved nothing, but fortunately, I am still among the gentlemen, bearing the honor of the son of heaven, following the emperor every day, waiting for inquiries, and praising my name inappropriately under the sun, not to mention anyone who can surpass me.

Now students are studying in imperial academy, and the court provides meals every day. Parents give them fur coats in winter and kudzu coats in summer, so don't worry about freezing and hunger. Sitting downstairs reading classics, there is no hard work; There are teachers like doctors, who ask for advice without asking themselves and get nothing; All the books you should have are concentrated here. You don't have to copy them by hand like me. You can borrow them from others before you can see them. If some of them are not proficient in their studies and their moral quality has not developed, if they are not talented and have low qualifications, they will not be as single-minded as I am. Can you say it's someone else's fault?

Dongyang Ma studied in imperial academy for two years, and his peers praised his virtue. When I went to the capital to see the emperor, Ma Sheng greeted me as a younger compatriot and wrote a long letter as a gift. He is fluent and approachable, arguing with him with gentle words and humble attitude. He himself said that he was very diligent and hard-working when he was a teenager, and he can be called a good learner! He was going home to meet his parents, so I specifically told him about my study difficulties. If I encourage fellow villagers to study hard, that is my ambition; If you denigrate me, brag about my experience and be proud in front of my fellow villagers, do you know me?
