Kuang Heng in the Han Dynasty was diligent and studious, but there was no candle lighting at home. There are candles in the neighbor's house, but the light can't reach his house, so Kuang Heng cut a hole in the wall to attract the neighbor's light, so that the light can shine on the book and read.

There is a big family in the same town who is illiterate and rich. There are many books at home. Kuang Heng went to his house as an employee, and he didn't want to be paid. The host was surprised and asked him why. He said, "I hope I can get your book and read it through."

Hearing this, the master sighed deeply and lent him the book. Therefore, Kuang Heng became a learned man.

2. Yeast

In the Jin Dynasty, Che Yin studied tirelessly since he was a child, but because of his poor family, his father could not provide him with a good study. In order to maintain food and clothing, there is no extra money to buy him lamp oil for evening study. But he can only use this environment and time to recite poems.

One night in summer, he was reciting an article in the yard when he suddenly saw many fireflies flying at low altitude. The flashing light is a bit dazzling in the dark. He thought that if many fireflies were gathered together, they would become a lamp!

So, he went to find a white silk bag, immediately caught dozens of fireflies and put them in, then tied the mouth of the bag and hung it up. It's not very bright, but it can be used for reading.

From then on, as long as there are fireflies, he will catch one to use as a lamp. Because he studied hard and practiced hard, he finally became an official in a high position.

3. Snow reflection

Sun Kang also came from the Jin Dynasty, and his situation was similar to that of Che Yin. Because I have no money to buy lamp oil, I can't read at night, so I have to go to bed early. He felt it a pity to let time pass in vain.

One night in the middle of the night, he woke up from his sleep, turned his head out of the window and found a ray of light in the window. It turned out to be a reflection of heavy snow. Why not borrow discerning to read? Sun Kang was so tired that he immediately got dressed, took out his book and went outside.

The snow reflected on the wide earth is much brighter than the snow in the room. Sun Kang ignored the cold and immediately read a book. His hands and feet were frozen stiff, so he got up and ran, rubbing his fingers at the same time.

From then on, every snowy night, he never missed this good opportunity and studied tirelessly. This spirit of hard work has promoted his knowledge to advance by leaps and bounds and become a land full of knowledge. Later, he also became a senior official.
