In the Tang Dynasty, Li Mi heard that Bao Kai was in Lushan and went to visit. He rode an ox, hung a roll of Hanshu on his horn, and read it while walking. Yang Su, the Duke of Yue, saw him on the road and followed him with a bridle, saying, "What book makes you so diligent?" Shi Biao said it was Xiang Yu Biography. Yang Su then talked with Shi Mi and thought that he was a wizard (see "Biography of Shi Mi in the New Tang Dynasty"). Later, I used the metaphor of "hanging a book in a corner" to study hard.

A capsule firefly reflects snow

This is an allusion composed of two stories. Saccharomycetes: Fireflies are packed in bags; Snow reflection: using the reflection of snow. Use the light of fireflies and the reflection of snow in your pocket to read at night.

Che Yin is a diligent reader, and he is well-read, but his family is poor, so he can't afford lamp oil. In summer, he puts dozens of fireflies in white cloth bags, and uses their light to read day and night (see Biography of the Book of Jin and Che Yin).

In the Southern Dynasties, Liang Sunkang's family was poor, and he had no money to buy lamps and candles. At night, he often read in the light of snow. Later generations often regard the two allusions of "a firefly reflecting snow" as a model of diligence.

Digging through the wall for light

In the Han Dynasty, Kuang Heng studied diligently without candles, and his neighbors had candles, so Kuang Heng dug a small hole in the wall and read by the light coming in next door (in Miscellanies of Xijing). Later generations used "digging the wall to borrow light" to describe diligent study and hard study.

Wei Bian San Jue

Wei Bian: In ancient times, bamboo slips were used to write books, and the bamboo slips were tied together with ripe cowhide ropes, which was called Wei Bian; Three: the approximate number refers to many times; Absolutely: broken. In his later years, Confucius liked to study Zhouyi and compiled Yi Zhuan which explained Zhouyi, such as Cohesion, Xiangci, Shuogua and Classical Chinese. Due to repeated reading of Zhouyi, the rope for compiling the simplified book was broken many times (see Historical Records Confucius Family). Post-pan is used to describe diligent reading.

the thorn-stock cantilever beam

Su Qin was born in Luoyang in the Eastern Zhou Dynasty. He went to the State of Qi to learn vertical and horizontal skills from Guiguzi. After he finished his studies, he went to lobby the king of Qin, wrote ten letters, but they were not used. The funds he brought with him ran out, and he returned home very awkwardly. His brother, brother, sister-in-law, sister, wife and concubine all secretly laughed at him, saying that he was doing nothing, gossiping and deserved it. After hearing this, Su Qin felt ashamed and secretly sad, so he made a determined effort to study. When he was sleepy, he stabbed his thigh with an awl, woke up, and then read again. Finally, he became the prime minister of the six countries and became the combined leader of the six countries. Later, I used the metaphor of "stabbing stocks" to study hard.
