''This book has been passed down from generation to generation, and it can be lived. ''
Hua Tuo, as a famous ancient and modern medical scientist in the Spring and Autumn period and the Warring States Period, together with Dong Feng and Zhang Zhongjing, was known as the "Three Divine Doctors of Jian'an", practicing medicine all over the country, good at surgery, and "Hua Tuo was alive" has become synonymous with medical skill.
In his later years, Hua Tuo died tragically in prison due to a proud surgical operation, and this sentence "This book is passed down from generation to generation, but it can be lived in the world"" is Hua Tuo's last plea to save the people of the world.
Hua Tuo's ups and downs were closely related to Cao Cao.

One is mighty, one is a savior, because of the Battle of Xuzhou, Cao Cao and Hua Tuo are related. In the thirteenth year of Jian'an (208), Cao Cao coerced Tianzi to depose the Three Dukes in the name of Emperor Xian of Han, set up the position of Chancellor, conquered the Four Directions of the Central Plains, eliminated eryuan, Lü Bu and other separatist forces internally, surrendered to the Southern Xiongnu, Wuhuan and other northern states externally, and unified northern China to appoint a chancellor. Cao Cao, who became the prime minister, counterattacked the Battle of Chibi with fewer victories and more, and rescued the talented woman Cai Wenji, manipulating the government with the true color of killing the decisive tyrant xiong, and taking over the power.
Book of the Later Han Dynasty. Fang Shu Column Biography. According to the biography of Hua Tuo, Cao Cao wanted Hua Tuo to stay in the palace for a long time and serve as his personal attendant, but Hua Tuo, who was born in the grassroots and cared about the people, immediately refused. Hua Tuo's refusal was determined by his character of not serving the magnates alone, but partly due to the influence of Cao Cao's early conquest of Xuzhou. In the Battle of Xuzhou, Cao Cao took the lead in crusading against Tao Qian's behavior, so that Xuzhou's blood flowed into a river, killing tens of thousands of people, and everywhere the pedestrians went were ''Chickens and dogs are exhausted, there are no pedestrians in The Ruins', as a xuzhou civilian Hua Tuo, who has lived here for many years but has seen the corpses of his hometown all over the field, the indignation in his heart is destined to have an "unusual past".
This was the first encounter between Cao Cao and Hua Tuo, which laid the groundwork for Hua Tuo's murder.
Cao Cao's headaches began to intensify at the Battle of Guandu with Yuan Shao. Before the war between the two of them began, Yuan Shao attacked his heart first, and sent Chen Lin, who was prominent in literary style, to write a sharp-tongued denunciation, telling all the stains of Cao Cao's political career since he entered politics: digging graves and digging graves, tyranny and dictatorship, and treacherous intentions to rob the country.
It can be seen that Cao Cao, who has always been suspicious, has been plagued by headaches, and as early as in the "Romance of the Three Kingdoms", he has mythologized the origin of his headaches. It is said that Cao Cao cut down a pear tree in order to build the palace. At night, Cao Cao dreamed that the pear god came to assassinate him, and when he woke up, he felt a headache, and the stimulation of the Battle of Guandu made the headache disease play to the extreme, so Cao Cao visited the famous doctor for a long time but no one could cure it, and someone recommended the divine doctor Hua Tuo to come to the rescue.
This was the first encounter between Cao Cao and Hua Tuo, which opened the prelude to the relationship between doctors and patients.
Hua Tuo, who had been recruited, could see at a glance that there was no cure for Cao Cao's headache. After treating Hua Tuo, a fierce general in Jiangdong, he said to Cao Cao after taking his pulse: He is terminally ill and has no cure. There is only one way to prolong life, that is, to drink the soup of the lungs first, cut off the head with a sharp axe, and remove the wind saliva, and then you can permanently remove the roots.
What does Hua Tuo mean? Cao Cao's headache was caused by a stroke, if you want to completely cut off the root of the headache, you have to do craniotomy, surgery is Hua Tuo's best strength, but everyone looks dumbfounded, looking at each other, but the heart is pinched for him sweat. Cao Cao was such a person, he was suspicious of killing and not blinking, and when he heard that someone wanted to open his skull and treat his illness, he suspected that this was not really a life-saving but his life.
Hua Tuo boldly said that he was imprisoned by Cao Cao for craniotomy, which is one of the versions of the story in "Romance of the Three Kingdoms".
In the second version of the story, Hua Tuo was killed because of a seemingly incompetent refusal, but in fact it was a deep meaning of raising his stature to seek an official name, which comes from Lin Zhenqing's "Fang Ji Biography".
Everyone only knows that Hua Tuo is devoted to medicine, but in fact, he is devoted to the shi. In the "Romance of the Three Kingdoms", it was recorded that Hua Tuo was a scholar who traveled to Xuzhou, and like everyone else, wanted to pass the national examination to enter the imperial court to do a career, so the lieutenant Huang Huan had invited him to be an official, and Chen Jue also recommended Hua Tuo to be filial piety, but he was arrogant and conceited, thinking that the two were not high and powerful, so he simply refused to go.
''Seeing a career with a doctor, meaning to often regret it'", this is Hua Tuo's refusal and regret that he did not seek an official and a half-job, all hidden in the books of the "Romance of the Three Kingdoms", he waited for the opportunity to enter the palace and enter politics, while engaging in his own hobby of medicine. Frustrated in the workplace, medical pride, Hua Tuo's medical skills are well-known, so Cao Cao specially invited him to treat headaches.
Hua Tuo treated for a short time, and then directly said: "This is difficult to help, and it can be treated for a long time." What he meant was that Cao Cao's disease was difficult to cure in a short period of time, and he still had to work hard in politics, and could only survive, and the only person who could be treated was Hua Tuo, so he was particularly confident to remind Cao Cao: The villain raises his illness and wants to be self-respecting.
A headache but said that life is not long, can cure this stubborn disease the world is only himself, inside and outside, Hua Tuo's pride and conceit in Cao Cao's view is to inflate his value, want to seek a career. Until a few days later, Hua Tuo, who had returned home for a long time, refused to come back, and shirked it because his wife at home was uncomfortable.
Several times he refused Cao Cao's anger and said bluntly: if he was really ill, he would forgive the date, and if he lied, he would be imprisoned for deception. Later, Hua Tuo was imprisoned.
When Cao Cao had a headache, there was no one to cure, and he himself did not regret killing the famous doctor, and even said loudly: ''Tuo can cure my disease, but I can't cure it, if I want to threaten him, I don't kill him, and the disease will be difficult to heal.'" In the text, Lin Zhenqing borrowed Cao Cao's mouth to say that behind Hua Tuoqing's conceit, he actually wanted to use the opportunity of curing his illness to blackmail him into the knighthood.
Of course, whether it was Luo Guanzhong's craniotomy or Lin Zhenqing's threat theory, the final result was that Hua Tuo was killed by Cao Cao, and a generation of divine doctors did not even pass on the "Qingneng Jing" written throughout their lives.
