How does the Book of the Later Han Dynasty record that Hua Tuo treated dizziness caused by head wind for Cao Cao?

China's acupuncture technique was famous in the Spring and Autumn Period and the Warring States Period. If this technique is used to save the comatose Prince Guo from danger, the Neijing systematically summarizes acupuncture and moxibustion, making it a theoretical and technical subject. Gold and silver needles for acupuncture were unearthed from the tomb in Mancheng, Hebei Province.

Both Zhang Zhongjing and Hua Tuo are famous for being good at acupuncture. For example, Hua Tuo, as the originator of surgery, is famous all over the world, but he is more widely known for treating dizziness caused by head wind by acupuncture for Cao Cao. "The Book of the Later Han Dynasty" records: "If you accumulate hardships, you will feel dizzy and your needles will be poor." In other words, Cao Cao was dizzy because of the head wind and could not be cured for a long time. When he had an attack, the pain was unbearable. When he heard about Hua Tuo's fame, he invited him to his side. If the pain occurs, Hua Tuo uses acupuncture to treat Cao Cao's headache, and the effect is quick. Therefore, Cao Cao tried to leave Huatuo as his doctor.
