There is no doubt that Cao Cao killed Hua Tuo, an imperial doctor, but it was not because Hua Tuo wanted to split Cao Cao's head to treat his headache, as mentioned in Romance of the Three Kingdoms, and Cao Cao suspected that he had hurt himself.
In fact, the history book The History of the Three Kingdoms records that Cao Cao killed Hua Tuo.
Hua Tuo was a famous doctor at the end of the Eastern Han Dynasty. He was known as an imperial doctor. His medical skills were superb, and he was good at surgery, acupuncture and the diagnosis and treatment of intractable diseases. Mafeisan, the earliest anesthetic in the world, was developed. It also created a set of health gymnastics-Wuqinxi, which is equivalent to the square dance in the late Eastern Han Dynasty.
at that time, Hua tuo was a member of the system, and a man with an iron rice bowl was equivalent to a state official, so he should obey the state's recruitment and dispatch. Cao Cao, the Prime Minister of Han Dynasty, is a concrete national symbol. Obeying Prime Minister Cao means serving the country. However, Hua Tuo, who prided himself on his superb medical skills, refused to be driven by the government and refused to be an official with Prime Minister Cao. On the grounds that his wife was ill, he lied to Cao Cao, and Cao Cao failed to recruit many times. Later, Cao Cao sent someone to find out the truth. In a rage, he was tortured and imprisoned, and then died in prison.
under the system, system and social environment at that time, Cao Cao deserved to kill Hua tuo.
