During the Warring States Period, Su Qin was so tired that he studied day and night that he stabbed himself in the leg with an awl to keep his head clear. Sun Jing of the Han Dynasty tied his hair to the beam with a rope to prevent him from falling asleep while studying. If he dozes off, he will be awakened. This is the story of "stabbing the stock and hanging the beam" in history.

2. Che Yin, Sun Kang and Kuang Heng

Che Yin, Sun Kang and Kuang Heng in the Jin Dynasty were so poor that they couldn't even afford to buy oil for lighting. In the summer night, Che Yin made a small pocket with gauze, caught a few fireflies and put them in, reading by the light of fireflies; Sun Kang sat in the snow on a cold winter night, studying hard through the reflection of snow; Kuang Heng cut a small hole in the wall and "stole" a little light from his neighbor's house to read. These are the stories told by the idioms "A firefly reflects snow" and "Digging a wall to steal light".

3. Sima Guang

Sima Guang had a poor memory when he was a child. Some people recite an article, reading it three or four times is enough, and reading it ten times is almost enough, but he has to read it dozens of times every time. In order to recite articles, Sima Guang often studies until late at night, but because he is also studying during the day, he is too sleepy to open his eyes at night, and sometimes he lies there and falls asleep in a daze.

Later, he had an idea and took a piece of wood as a pillow. At midnight, as soon as he turned over, the log rolled away. When his head fell off, he woke up immediately and could get up and continue reading. He called logs "police pillows". From then on, he got up early every day to study, persevered, and finally became a knowledgeable writer, writing "Zi Tongzhi Jian".

4. Barene

Barene was disabled by illness when she was a child, and her mother felt like a knife, but she endured grief. She thinks that what children need most now is encouragement and help, not mother's tears. Mother came to Barone's sickbed, took his hand and said, "Son, mother believes that you are an ambitious person. I hope you can bravely walk on the road of life with your own legs! Good Barene, can you promise your mother? "

His mother's words hit Barene's heart like a hammer. He threw himself into his mother's arms and burst into tears. Since then, whenever my mother is free, she will practice walking and doing gymnastics for Barene, and she is often so tired that she sweats. Once my mother caught a bad cold. She felt that a mother should not only teach by example, but also set an example. Despite her high fever, she got out of bed as planned to help Barene practice walking.

Soybean-like sweat dripped from her mother's face. She wiped with a dry towel, gritted her teeth, and helped Barene finish the exercise plan for the day. Physical exercise makes up for the inconvenience caused by disability to Barene. His mother's example deeply educated Barone, and he finally withstood the severe blow of fate. He studies hard and his academic performance has always been among the best in his class.

Finally, he was admitted to the Medical College of Vienna University with excellent results. After graduating from college, Barene devoted all her energy to the research of otology. Finally, I finally got on the podium of the Nobel Prize in Physiology and Medicine.

5. Wang Xizhi

Through diligent study and hard practice, Wang Xizhi finally became a famous calligrapher and a "book saint".
