Hua Tuo was a Han Chinese with good medical skills in the history of the Three Kingdoms, because he developed many advanced drugs of that era, and has been admired by the world until now. When he was treating Cao Cao, he proposed to do craniotomy "surgery" for Cao Cao, and was beheaded by Cao Cao in anger, and many people expressed great sympathy for this, believing that because of this treatment method that seemed to be "murder" at the time, Hua Tuo was beheaded and died too unjustly.
So that in the later period, when Cao Cao lost his beloved son Cao Chong and regretted that he had beheaded Hua Tuo early, most people still had the idea of "deserving" in their hearts. But in fact, if everyone knows what Hua Tuo did at that time, they will understand why Cao Cao, who has always "established the rule of law", would be angry at Hua Tuo for a while without controlling himself.
Hua Tuo was also familiar with the scriptures, but he went farther and farther on the road of trying to become an official, and what finally made him shine in the Eastern Han Dynasty was his hobby, medical skills. Most of the Han people's ideas about Cao Cao were traitors, and the same was true of Hua Tuo, who had read books, but Cao Cao's power in the north was already unshakable, so when Cao Cao found Hua Tuo for treatment due to headaches, Hua Tuo still obeyed the orders although he had a rebellious heart in his heart.
Until later, Cao Cao's headache became more and more unbearable, and Hua Tuo took the opportunity to have a proposal to "open his skull", and Hua Tuo's hidden thoughts in it were self-evident. However, the reason why Cao Cao really killed Hua Tuo was actually that Hua Tuo deliberately refused to accept Cao Cao's summons many times, and found an excuse to lie that his wife was ill and needed to take leave to go home to take care of her. After Hua Tuo returned home, Cao Cao summoned Hua Tuo many times due to headaches, the letter could not be invited, and the officials did not return, and when Cao Cao sent troops to Hua Tuo's home to check, he found that Hua Tuo was deceiving himself, and Hua Tuo's wife in the family was not in serious trouble.
Hua Tuo also committed two felonies, deception and disobedience, which could be beheaded for "great disrespect" by virtue of these two in the Han Law. Therefore, Cao Cao was angry and beheaded Hua Tuo, first, because of Han Law, second, because Hua Tuo had the intention of rebellion, and third, he had a long-term method of remission, but he did not rescue him for this reason. These three points that Hua Tuo did should have been cut off long ago wherever they were placed. It dragged on until the end to behead him, but Cao Cao still hoped that he could alleviate his headache symptoms, so people in later generations were again wronged by Hua Tuo.
