1. Suspended beam thorns

During the Eastern Han Dynasty, there was a young man named Sun Jing who was diligent and studious. He would read from morning to night behind closed doors and seldom rest. Sometimes at midnight It’s easy to doze off in the middle of the night.

In order not to affect his studies, Sun Jing came up with a way. He found a rope and tied one end to his hair and the other end to the beam of the house. When he was dozing off, as long as he lowered his head and the rope pulled his hair and hurt his scalp, he would wake up from the pain and continue reading.

Su Qin was a famous politician during the Warring States Period, but he did not have much knowledge when he was young. No one paid attention to him in many places. Even if he had ambitions, he could not be reused, so he made up his mind. Determined to work hard and study hard.

Because he often read until late at night, and when he was so tired that he wanted to take a nap, he would prick his thigh with the awl prepared in advance. The sudden pain made him wake up suddenly and cheer up to continue reading.

2. Cutting through walls to steal light

In the Han Dynasty, there was a man named Kuang Heng who was diligent and studious, but his family was very poor and could not afford candles. Kuang Heng had to work during the day and at night. Only when he had time to study, Kuang Heng had no choice but to study hard by candlelight in a small hole in his neighbor's house. Finally, he became a famous scholar by reading poetry and books.

3. Nangying Yingxue

Che Yin, whose courtesy name was Wuzi, was from Nanping, Shanxi (now Anxiang and Jinshi). Che Yin has been eager to learn since he was a child, but because his family is poor, he has no money to buy lamp oil to study at night. Therefore, at night, he could only recite poetry.

One summer night, while he was reading a book outside his house, he suddenly saw fireflies flying in the sky like stars in the field. He had a sudden thought: Isn't the light of fireflies just like lamps in the dark night? This way I can study hard all night long!

Thinking of this, he immediately found white silk and tied it into a small bag, and caught dozens of fireflies and put them in it, and put them in the room. It turned out to be a lot brighter.

Che Yin studied hard in this way, and finally became a very learned man. He served as the governor of Wuxing, the general of the auxiliary state, and the minister of the Ministry of household affairs.

The same was true for Sun Kang of the same dynasty. Since I had no money to buy lamp oil, I couldn't read at night and had to go to bed early. He felt it was a pity to let time slip away like this.

One night in the middle of the night, he woke up from his sleep. When he turned his head to the window, he found a ray of light coming through the crack of the window. It turns out that it is reflected by the heavy snow, and you can use it to read a book. So he suddenly lost his tiredness, immediately got dressed, took out his books, and went outside.

The light of snow reflected on the broad land is much brighter than inside the house. Regardless of the cold, Sun Kang immediately started reading. His hands and feet were frozen, so he got up and ran, rubbing his fingers at the same time.

From then on, whenever there was snow at night, he would not miss this good opportunity and study tirelessly. This spirit of hard study promoted his knowledge to advance by leaps and bounds, and he became a well-educated man. Later, he became a high official.
