Qing nang Shu was written by Hua Tuo.
Qingnangshu is a book in the romance of the Three Kingdoms, written by Hua Tuo. During the Three Kingdoms period, Cao Cao had a headache, so he asked Hua Tuo to see a doctor. When Hua Tuo intended to open his skull for Cao Cao to induce "wind saliva" and cure his migraine, Cao Cao mistakenly thought that Hua Tuo would harm him and put him in jail. Hua tuo expected that he could not escape from Cao Cao's palm, and in prison, he taught the Qing nang Shu, which was made by his own life experience, to the prison leader.
Everyone knows that The Romance of the Three Kingdoms is a novel, but the passage about Qingnangshu is a joke, but it is not completely out of context. In fact, the story of "Hua Tuo's book delivery jailer" has been mentioned in the official history "Biography of Hua Tuo in the Three Kingdoms" and "Biography of Hua Tuo in the Later Han Dynasty", but the content is simple and far less story-telling than that written in the Romance of the Three Kingdoms.
