Influenced by the Romance of the Three Kingdoms, many historians today believe that Hua Tuo is not only brilliant in medical skills and noble in medical ethics, but also always cares about the sufferings of the people all over the world.

Refuse to serve the dignitaries as their agents and treat Cao Cao alone. So he left Cao Cao on the pretext that his wife was seriously ill. Cao Cao repeatedly urged him to come back, but he refused. Finally, Cao Cao killed him in a rage.

Is it true that all the responsibility for Hua Tuo's death lies with Cao Cao? Is it true that Hua Tuo didn't make a mistake? Professor Xu Shaojin of Nanjing Audit University and teacher Lin Zhenqing of Hebei Pingquan Normal School for Nationalities believe that the responsibility for Hua Tuo's death is not entirely in Cao Cao. The publication of two papers finally solved the real reason for Hua Tuo's murder.

Why did Cao Cao kill Hua Tuo? The Romance of the Three Kingdoms profoundly explains this point.

In Chapter 78, Luo Guanzhong described in detail how Cao Cao killed Hua Tuo. In order to build the first temple, Cao Cao personally cut down the pear tree in front of Yuelong Temple with his sword, which offended the god of pear trees. That night, he had a nightmare. After waking up, he continued to have a headache. He found a good doctor, but it was useless.

Later, Hua Tuo recommended Hua Tuo to Cao Cao, and Cao Cao immediately sent someone to invite Hua Tuo to see him in the evening.

Hua Tuo thinks that Cao Cao's headache is caused by a stroke, which is rooted in his head. Drinking some soup can't cure it. You must first drink "Ma Fei Tang", an anesthetic invented by Hua Tuo, and then split his head with a sharp axe and take out "wind saliva" to remove the root of the disease.
