one summer evening, he was reading an article in the yard. Suddenly I saw many fireflies flying in the low air. The flicker of light was dazzling in the dark. He thought, if you put many fireflies together, it will become a lamp. So he went to find a white silk pocket, caught dozens of fireflies and put them in it. Then he tied the pocket and hung him up. Although it was not very bright, it could barely be used for reading. From then on, as long as there are fireflies, he will go to grab one as a lamp. As a result of his hard work, he finally became a senior official
the same is true of Sun Kang of the same era. Because he had no money to buy lamp oil, he could not read at night and had to go to bed early. He thought it was a pity that time had run away in vain
in the middle of the night, when he woke up from his sleep and turned his head to the window, he found a light in the crack of the bed. It turns out that the snow is coming out, you can use it to read. So he got dressed, took out his books and went outside. The light of snow on the wide land is much brighter than that in the house. Regardless of the cold, Sun Kang immediately began to read. His hands and feet were frozen, so he got up and ran, rubbing his fingers. Since then, whenever there was snow in the evening, he would not miss such a good opportunity to study tirelessly. This kind of spirit of painstaking learning promoted his knowledge to advance by leaps and bounds and made him a learned man. Later, he became a senior official and did a lot of good things for the people< Fan Zhongyan was born in the Northern Song Dynasty. When he was two years old, his father died of illness, and his mother was destitute, so she had to take Zhongyan in her arms and remarry to a family surnamed Zhu. Fan Zhongyan grew up in Zhu's family
Fan Zhongyan has studied very hard since he was a child. The Zhu family is a rich family. However, in order to encourage himself, he often goes to the temples on the nearby mountains to study. That's why his life is extremely hard. He only cooks a pot of thick porridge every day, turns it into four pieces when it's cold, takes two pieces in the morning and two pieces in the evening, mixes a few pickles, and continues to study after eating. Sometimes I feel tired when reading at night, so I wash my face with cold water to dispel sleepiness. His spirit of studying hard left a deep impression on the monks
after becoming an official, Fan Zhongyan criticized the current situation, was impassioned and often ignored his own safety. He assiously encouraged himself, and did not eat much meat. His wife and children were only self-sufficient. He often recites: "the scholar should be the first to worry about the world, and the later to be happy."< When Zhang Haidi was 5 years old, she suffered from spinal cord hemangioma and high paraplegia, so she didn't go to school. When she was a child, she began to teach herself knowledge with indomitable perseverance. She taught herself professional courses in primary school, middle school and university. When Zhang Haidi was 15 years old, she was sent to a poor mountain village in Shenxian County, Liaocheng with her parents. However, she was not afraid of hard life, but devoted her youth with an optimistic and upward spirit. There, she taught the children in the village primary school, overcame all kinds of difficulties to learn medical knowledge, and enthusiastically treated the villagers with acupuncture and moxibustion. During her stay in Shen County, she treated more than 10000 people for free, and was warmly praised by people

He also translated 130000 words of English novels, wrote a large number of literary works and made remarkable achievements.
