It is recorded that it was when Yuan Shao was defeated, the monarch was held hostage, and he gave orders in the name of the monarch that his career began to flourish. The more he thinks about things, the more serious his headache begins to get. In fact, he suffered from wind and evil. Because he has been involved in the war for many years, he will certainly encounter frequent storms. Moreover, he has too much desire, bad temper and too many thoughts, which leads to his weak constitution. The human head is the most vulnerable to wind evil, and Hua Tuo can only give him acupuncture to relieve pain.
He may have high blood pressure, because he likes eating meat and drinking, even regardless of his health. Hua tuo repeatedly advised him not to drink or eat meat, but Cao Cao always disagreed and went his own way, and Hua tuo had no choice. Cao Cao's bad temper and excitability are also obvious characteristics of hypertension, which can cause headaches. In any case, Hua tuo had no chance to murder him. He has no rancor with Hua Tuo. If Hua Tuo kills him secretly, he can't escape. Hua tuo wanted to cut his head open just to cure Cao Cao's illness. In Hua Tuo's view, the tumor on Cao Cao's head is too big to be cured with drugs. The only way is to open his head for surgery. This is the only way to treat Cao Cao's headache.
Because it was a long time ago, we can't even understand the ins and outs of many things in history. According to historical records, Hua Tuo was born in 145 and died in 208. Moreover, there are relevant historical records, saying that he 150-60 years old, but has always maintained the appearance of his 60 s, which is simply white-haired and childlike. But according to reality, Hua Tuo may have lived over 63 years old.
