The story is about Kuang Heng, a famous scholar of the Western Han Dynasty, who was born in a peasant family and lived in poverty. He was always eager to study, but his parents couldn't afford to send him to school, and they couldn't even afford to buy books, so Kuang Heng had to borrow books from other people to read.

One night, Kuang Heng wished to read a book before going to bed, but because his family was so poor that they didn't even have any lamp oil, they couldn't light a lamp to read. When Kuang Heng was worried, he suddenly noticed that the light was coming through the cracks in the wall, which was the neighbor's light. Kuang Heng had a plan, so he used a chisel to dig the small crack into a small hole, and then held the book, leaning against the wall, using the weak light to read. From then on, Kuang Heng borrowed the neighbor's light every night, burying his head in hard reading, and finally became a famous scholar.

Su Qin is the man who stabbed himself with an awl and a beam on his head. Su Qin was a native of Luoyang in the Eastern Zhou Dynasty during the Warring States period, and his name was Jizi. Su Qin was a native of Luoyang, although he came from a humble background, but he had a great ambition. After years of learning the art of persuasion under the tutelage of Guigu Zi, he saw his fellow students Pang Juan and Sun Bin going down the mountain to seek fame and fortune, so he also bid farewell to his teacher Zhang Yi and went down the mountain. Zhang Yi went to the state of Wei, while Su Qin traveled for years in the Great Powers, but accomplished nothing and had to return home in a sorry state.

When Su Qin returned home, his brother, sister-in-law, brother-in-law, sister-in-law, and wife all mocked him for not doing his job, and only knew how to talk. When Su Qin heard these mocking words, he felt very ashamed in his heart, but he had always wanted to lobby the world and seek fame, so he asked his mother to sell his family's property, and then traveled around the world again.

Su Qin often encouraged himself by saying, "A scholar has already decided to take the road of studying to gain fame, if he can't obtain a noble and honorable position with the knowledge he has learned, what's the use of reading even more!" Thinking of these, Su Qin more forgetful study up.

In order to grasp the time to study, Su Qin also came up with a good way. When he was reading, he tied his hair with a rope and hung it on the beam, so that if he dozed off, his hair would pull him awake. Late at night, if he felt sleepy, he took an awl and stabbed himself in the thigh, so that he could stay awake. This is the origin of the idiom "head hanging from a beam, cone stabbing the stock".
