Li Bai, a famous poet in Tang Dynasty, never studied hard when he was a child. He often throws away his books and goes out to play. One day, Li Bai met a white-haired old woman who was grinding a big iron bar on a stone. She was curious and asked what she was doing. The old woman told him to grind it into an embroidery needle. Li Bai was deeply moved, studied hard and finally became a writer.
Luban made a saw.
Once, the king ordered Lu Ban to cut down 300 trees in fifteen days to build a big palace. Lu Ban and his disciples worked hard for ten days, but only cut down more than one hundred trees. Luban is very worried. He can't sleep at night. When he came to the Woods, he suddenly felt that his hand was cut. When he saw it, it was cut off by a thatch. He also saw that the big die and silk grass of a big locust were good teeth. After thinking hard, Luban finally invented a saw, which is very convenient to use.
3. Confucius read Yi.
Confucius "liked the Book of Changes in his later years" and spent a lot of energy reading the Book of Changes many times, with many annotations. I don't know how many times he opened it. After reading this, Confucius still said modestly, "If I live a few more years, I can fully master the text and quality of Yi."
4. Hua Tuo studied medicine
Hua tuo studied hard all his life. Hua Tuo went to Xuzhou to study, familiarizing himself with classics, especially studying medicine for health preservation. He works hard and is knowledgeable. During the period, I worshipped famous doctors as teachers and humbly asked for advice. The valuable medical heritage of Bian Que and Zhang Zhongjing laid a solid theoretical foundation. In many years of clinical practice, I have extensively collected prescriptions, contacted cases in many ways, and summed up the experience of the masses. Hua Tuo wrote many books about his rich clinical experience in his life.
5. Compendium of Materia Medica compiled by Li Shizhen in twenty-seven years.
Li Shizhen, whose real name is Dong Bi, was born in Hushan in his later years. His ancestral home is qi zhou, Hubei Province (now qi zhou Town, Qichun County, Huanggang City, Hubei Province), Han nationality, and his father Li Yanwen is a local famous doctor. Li Shizhen inherited family studies, attached importance to materia medica, was full of practical learning spirit, and was willing to learn from working people. At the age of 38, Li Shizhen was called by the King of Chu to Wang Fu as a "temple official" in Wuchang to take charge of the affairs of the good doctor's office. Three years later, he was recommended by his wife's hospital to go to Beijing for sentencing. Thai Hospital is a medical institution specially serving the imperial court. It was messed up by some quacks at that time.
Li Shizhen worked here for only one year, then resigned and returned to China. Li Shizhen consulted more than 800 books on medicine and its academic research in past dynasties, combined with his own experience and investigation, and compiled Compendium of Materia Medica for 27 years, which is a summary masterpiece of pharmacology in Ming Dynasty.
