First, Sun Jing (a famous politician in the Eastern Han Dynasty)

When he was young, Sun Jing was eager to learn, often behind closed doors, and kept reading alone. He often forgets to eat and sleep from morning till night. Because of the long study time, he tends to doze off when he is tired. Sun Jing thought of a special way for fear of affecting his study. He found a rope, one end tied to his hair and the other end tied to the beam. As long as he dozes off while studying, the rope will prick his scalp and people will wake up immediately. Later, Sun Jing became a famous politician in the Eastern Han Dynasty, and his efforts changed his fate.

Second, Su Qin (a famous politician in the Warring States Period)

When Su Qin was young, due to his limited knowledge, he went to many places to do things, and was not taken seriously. After returning home, his family was also very cold and looked down on him. This is a great stimulus to him. So he hates studying hard and reads late into the night every time. Every night, he wants to take a nap, so he prepares an awl. Every time I get tired, I take out my awl and stab myself in the thigh. The pain woke him up and went on reading. In the end, Su Qin became a famous politician in the Warring States Period, and his efforts changed his fate.

Third, Che Yin (a celebrity in Jin Dynasty)

Che Yin studied tirelessly since he was a child, but because of his poor family, his father couldn't provide him with a good learning environment, and even he couldn't afford an oil lamp for reading at night. One summer night, when he was endorsing in the yard, he saw a lot of fireflies flying around, so he caught a lot of them and put them in a white silk bag, using the faint light from fireflies to learn. Finally, he became a celebrity in the Jin Dynasty, and his efforts changed his fate.

Fourth, Sun Kang (a celebrity in Jin Dynasty)

When Sun Kang was young, he went to bed early every day because his family was too poor to buy lamp oil. Once I woke up from my sleep and found that the snow outside the window reflected the light in the room. I didn't feel sleepy either, so I got up and went to study in the yard. Every snowy night, he never loses the opportunity to learn. In this way, his knowledge advanced by leaps and bounds and eventually became a celebrity in the Jin Dynasty. His diligence and progress changed his fate.

Verb (abbreviation of verb) Kuang Heng (a famous person in the Western Han Dynasty)

Kuang Heng liked reading very much when he was a child, but his family was too poor to buy lamp oil, so he couldn't study at night. His house is separated from his neighbor's by a wall. Once he accidentally saw a crack in the wall, and the neighbor's light shone a little on his house from the crack, so he found a chisel and cut a small hole in the crack. So, a lamp shines on his house, and he studies under this lamp. Finally, efforts and progress changed his fate.
