The details are as follows:

1. Kuang Heng

During the Han Dynasty, Kuang Heng was a very diligent and studious boy. Because his family was very poor, he had to do a lot of work during the day to earn money. Only at night could he sit down and read in peace.

However, he couldn't afford candles, and he couldn't read when it got dark. Kuang Heng was heartbroken for this wasted time, and felt very painful inside.

His neighbor's family is very wealthy, and candles are lit in several rooms at night to light up the house. Kuang Heng plucked up the courage one day and said to his neighbor: "I want to study at night, but I can't afford a candle. Can I borrow an inch of your house?"

Neighbors have always looked down on people who are poorer than theirs. He said viciously: "If you are too poor to buy a candle, why should you study?" Kuang Heng was very angry after hearing this, but he was more determined to study well.

Kuang Heng returned home and quietly cut a small hole in the wall. The neighbor's candlelight came through the hole. With this faint light, he began to read books eagerly, and gradually read all the books at home. Kuang Heng studied diligently in this way. Later he became the prime minister of Emperor Yuan of Han Dynasty and became a famous scholar in the Western Han Dynasty.

2. Zhang Haidi

Zhang Haidi suffered from epidural vascular disease when she was five years old. In the following sixteen years, she underwent four major surgeries and removed six vertebrae. She lost consciousness from the second thoracic vertebra down, accounting for two-thirds of her body.

Zhang Haidi challenged fate with tenacious perseverance, overcame various difficulties, taught himself basic elementary and middle school courses, and read more than a thousand books on politics, literature, medicine, foreign languages, etc. Hard work paid off, and she finally mastered certain medical skills and was able to treat some common diseases and frequently-occurring diseases. In more than ten years, she treated more than 10,000 people.

3. Helen Keller

Adversity is never an excuse, no matter how bad the cards are, they must produce amazing results. American female writer Helen Keller became deaf-mute when she was nineteen months old. As a result, the world fell into darkness and silence. For a disabled person, it is simply impossible to learn to read, write, and speak under such circumstances without a strong memory. However, Helen Keller did not give in to fate. With the help of her teacher Sullivan, she studied hard and shocked the world with her indomitable tenacity.

Ten hours a day, Helen Keller never slacked off and never slacked off. Her enthusiasm for actively seeking knowledge was high and she remained so for decades. She has a belief: she must write down the knowledge she has learned and become a useful person! Because of this, she overcame various difficulties, studied tenaciously, and successfully graduated from Harvard University's DeCliffe College. While writing, she was committed to charity, worked tirelessly, and made outstanding contributions to the world's cultural field and charity.

4. Beethoven

Beethoven studied music with his father since he was a child. He showed his musical talent very early, but the poverty of his family brought him a lot of troubles. As a boy, Beethoven took on the burden of life prematurely and began to worry about economic issues and how to earn daily bread.

Beethoven's childhood was so miserable, and his youth was even more painful. After the age of twenty-five, the demon of disease began to torment Beethoven. Between 1796 and 1800, ear diseases began to appear. Beethoven felt his ears ringing day and night, and his heart was tortured by severe pain. His hearing gradually deteriorated, and eventually he became completely deaf in both ears.

For a pianist and musician in his prime and with great ambitions, hearing loss is like the end of the world. But Beethoven fought tenaciously and said the famous saying that has been passed down through the ages: "I will hold the throat of fate, and it will never make me surrender."

5. Fan Zhongyan

Fan Zhongyan's family background was not good. When he was still very young, his father died of illness. Because the family was too poor, his mother had no strength to keep Fan Zhongyan alive on her own. In the end, there was no other way. His mother remarried to a family named Zhu. With her mother's remarriage, his surname was also changed to Zhu.

Fan Zhongyan lived frugally in order to study. Finally, his diligence and studious moved the elders of the temple, and the elders sent him to study in Nandu Academy. Fan Zhongyan still adheres to a simple living habit and does not accept gifts from wealthy children in order to sharpen his will.

After studying hard, he finally became a great writer.
