1. Reading in the middle of the month: Nanqi Jiangbi's family was poor. He makes shoes for a living during the day and finds time to study at night. When he can't light the lamp, he takes the book to the roof and reads by moonlight. Bai Juyi said in a poem: "There is no cloud in the sky, and there is a moon in the mountain pavilion. Read the bright moon and sing in the wind." Meng Jiao once wrote a poem, "When the night is poor, the bright moon shines on my book", which shows that many people in ancient times had the experience of borrowing the moon to study.

2. Blister fireflies reflecting snow: Blister fireflies reflecting snow means that Che Yin and Sun Kang in the Jin Dynasty could not light up at night in order to study. Che Yin catches fireflies in summer and puts them in silk bags for lighting, while Sun Kang studies them under the snow in winter. Later, this allusion was quoted in Saint Amethyst: "Like a firefly, like a snow, although my family was poor, I never stopped studying."

3. Digging the Corner to Steal Light: Kuang Heng, a scholar in the Western Han Dynasty, came from a poor family and was eager to learn. There was no light at night, so he dug a hole in the wall to read by his neighbor's candlelight. There are many books in a large local family, so Kuang Heng went to his house to work, but he didn't want to be paid. The master was surprised and asked him why. He said, "I want to get the master's books and read them all." The host was very moved and gave him books as a reward. Later, Kuang Heng became a learned scholar.

4. Study hard under the ever-burning lamp: Wang Mian, a painter and poet in Yuan Dynasty, was born in a peasant family. When he was a child, he had to help others herd cattle and do odd jobs. One day, he borrowed a book he had long wanted to read, but he was too busy working in the temple during the day to breathe. Second, the old monk wouldn't let him read while working, so he had to read at night. But having no money to buy lamp oil, studious Wang Mian suddenly thought: Isn't there a ever-burning lamp in the Buddhist temple? There, the old monk won't go at night, it's very quiet and there is no interference. Late at night, he came to the Buddhist temple and saw the ever-burning lamp swaying in the breeze, and the faint light shone on the Buddha statue, which looked gloomy and terrible; But his strong desire for peace encouraged him to climb to the Buddha's knee and read his favorite book with an ever-burning lamp. He was so absorbed that he soon forgot everything around him. Since then, under the ever-burning light of the Buddhist temple, a child has been studying hard every day.

5, Ouyang Xiu paved sand literacy: Ouyang Xiu, a famous writer in the Song Dynasty, lost his father at the age of four, and his mother washed clothes and needlework for others to maintain a family life. At school age, Ouyang Xiu was too poor to go to school and had to follow his mother. He poured the fine sand into the yard as paper and the reed pole as a pen. Ouyang Xiu learns Chinese characters from his mother every day and receives training and education. After a while, Ouyang Xiu can read some books. With the ability of self-study, he worked harder, was admitted to Jinshi at the age of 22, and later became a famous prose master.

6. Hanging the beam and stabbing the stocks: Sun Jing studied hard in the Han Dynasty. He read the bright moon from dawn without a moment's rest. If you feel tired and want to take a nap, tie a rope around your head and hang the other end of the rope on the roof beam, so that you won't doze off and keep yourself awake all the time. With this strength, Sun Jing finally became a contemporary scholar. During the Warring States Period, Su Qin was born in poverty and was often looked down upon, but he studied very hard. If he is sleepy, stab him in the thigh with an awl and blood will flow to his ankle. The sharp pain reminded him to keep pushing. In this way, Su Qin finally learned everything, hung up the national seal of the six countries, and presided over the joint anti-Qin plan.

7. Burning ointment: Han Yu, a famous writer and philosopher in the Tang Dynasty, said in the "Self-report of Learning Experience": "The mouth is full of articles on six arts, and the hand is constantly covered with the compilation of a hundred schools of thought. ..... Burn ointment (ointment, lighting oil) continues (臰: reading, sun shadow, metaphorical time), but perseverance (constant: diligence) can make you poor. " When reading, he often recites the Six Classics in his mouth and keeps leafing through various classics in his hand, from lighting the oil lamp to dawn, day and night, year after year. In the future, "burning ointment" has become an allusion to efforts. When people read a series of famous works by Han Yu and admire his vigorous, powerful, magical and vivid words full of artistic charm, will they think of his days and nights?
