The story of "Hanging Beam" can be found in Taiping Guangji (Volume 363), which is quoted from Hanshu: In the Eastern Han Dynasty, there was a man named Sun Jing, who was a famous politician. At first, because of his shallow knowledge, he was not reused, and even his family looked down on him, which greatly stimulated him and made him determined to study hard.

Often behind closed doors, reading alone. Reading from morning till night every day, often forgetting to eat and sleep. After studying for a long time, I am tired, but I still don't rest. After a long time, I was too tired to doze off. Afraid of affecting his study, he came up with a special method.

In ancient times, men had long hair. He found a rope and tied it firmly to the beam. When he is tired of reading, he dozes off. When his head is lowered, the rope will hold his hair and hurt his scalp, wake up immediately and continue to study.

Step 2 pass light through the wall

Kuang Heng, the prime minister of the Western Han Dynasty, had no condition to go to school because of his poor family. He worked for people during the day and had no money to buy lamp oil at night, so he had to dig a hole in the earth wall at home, borrow the lamp next door to study, and even went to a family with books to help for free in exchange for books. He worked hard and finally became the prince and young master of the Han and Yuan emperors.

3. Fireflies covered with snow

During the Jin Dynasty, Sun Kang loved learning when he was young, and often felt that time was not enough. He wants to study day and night, but his family is poor and has no money to buy lamp oil. You can't study when it's dark.

Especially in winter, when the nights are long, he sometimes toss and turn for a long time, making it difficult to sleep. There's really no choice but to read more books during the day and sleep in bed at night. He felt it a pity to let time pass in vain.

One night, when Sun Kang woke up from his sleep and turned his head to the window, he found several white lights coming in through the window. I saw a heavy snow when I opened the door. The roof is white, the ground is white, and the trees are white. The whole earth was covered with a layer of silver, shining and dazzling.

4. Hang books in the corner

When Shimi was a teenager, she studied hard and was very motivated. He learned that there was a famous man named Bao Kai in Guishan, so he went to learn from him. Shi Biao set off on a cow with cattail grass on its back and a book "Han Shu" hanging on its corner.

Shi Mi was reading The Biography of Hanshu Xiang Yu when he was on the road. It happened that Su Yang, the king of Yue, rode a fast horse to catch up from behind, reined in his horse and praised him: "Such a diligent scholar is really rare!" Looking back, the young scholar turned out to be the King of Yue, and quickly jumped down from the cow's back to salute.

5. Bian Wei Three Musts

Confucius studied all his life and fell in love with the Book of Changes in his later years. However, because the Book of Changes is very difficult to understand, it is particularly difficult to learn, but Confucius is not afraid of suffering and has been reading it again and again until he fully understands it. Because paper had not been invented at that time, books were all written in bamboo slips or wooden slips, which were not only stupid but also heavy.

They pieced together many bamboo slips with thongs to make a book. But because Confucius studied too hard, he frequently exhibited books and bamboo slips and broke pimps three times. Therefore, later generations created the idiom "Bian Wei's Three Musts" to praise Confucius' studious spirit.
