There was once a widely circulated story, and even later people often used it: scraping bones to cure poison without saying a word became a good boy who praised Zhengzheng's iron bones.
This word originated from Guan Yu's saying during the Three Kingdoms period.
Guan Yu flooded the Seventh Army, captured Yu Ban, and after beheading Pound, he shouted at Cao Ren again: "Cao Ren Pifu, Pound De, and Yu Ban are not my opponents, not to mention er and other rats, if they don't surrender kaicheng early, when will they stay?" Cao Ren ordered, "Send poisoned arrows!" Cao Bing fired ten thousand arrows, and Guan Yu was shot by a poisonous arrow, which hit him in the right arm, and later asked the divine doctor Hua Tuo to help Guan Yu heal his wounds. Guan Yu saw Hua Tuo and hurriedly said, "Please! In the next occasional small sickness, how did the gentleman know in Jiangdong? Uh please use tea!" Hua Tuo took the tea and asked, "Junhou is injured in his right arm?" Guan Yu nodded, and Hua Tuo said, "Then please undress!" Guan Yu said: "Sir has worked hard all the way, rest for the time being, and it is not too late to cure it in the next day!" Hua Tuo said, "The prince's body is important, can he delay it?" Please undress!" Guan Yu took off his clothes, and Hua Tuo looked at Guan Yu's wound and said, "This is a crossbow arrow injury, the arrow is poisonous, but it penetrates the muscles and bones, fortunately, it is two or three days late, this arm is only afraid that it will be difficult to protect." ”
Guan Yu asked, "Oh? So sir has a cure?" Hua Tuo smiled and said, "Since I have come here, I have my own therapy, but..." Guan Yu said, "Sir, I have always regarded death as a homecoming, what am I afraid of?" How exactly does sir deal with the law? But it doesn't hurt to talk about it!" Hua Tuo said, "First set up a large ring in a quiet place, ask the prince to wear the wounded arm through the ring, tie it with a rope, and then take a thick blanket to cover the general's face, and then he can use his hands to heal the poison." Guan Yu asked incomprehensibly, "Sir healed my right arm, but why did he cover his face?" Hua Tuo replied, "All that cures bones must be like this, because during the treatment, the skin and flesh are turned outward, the blood is flowing, and the wounded person is terrified and trembling when he sees nature, so I can't do it." Guan Yu asked, "When Sir heals, can he use a knife?" Hua Tuo said: "First use a sharp knife to cut the skin and flesh, go straight to the bone, scrape off the arrow poison on the bone, apply the medicine well, and then suture the wound with a thin thread, so that it will be fine." Guan Yu nodded and asked, "I don't know what Mr. Guan's sword looks like?" Hua Tuo took out the knife and gave it to Guan Yu, who looked at it and said, "This knife is a hundred times smaller than my Green Dragon Sword, and the sharpness is even greater!" Hua Tuo said: "The general passed the prize, but..." Guan Yu asked: "Afraid I am afraid?" Hahahahahaha, cut the skin and flesh, straight to the bone, so easy. Guan Yu asked Yizi Guan Ping to prepare wine, asked Ma Liang to accompany him to play, Guan Yu drank and played chess, Hua Tuo sat next to him, guan Yu asked: "Mr. Hua Tuo, why don't you do it yet?" Hua Tuo said, "Uh... I'm waiting for the general, is the pillar hoop ready?" Guan Yu smiled, "Give me a knife, no pillar iron ring!" Hua Tuo stood up and said, "General, this pain is unbearable!" Guan Yu took a sip of wine and said, "I am not a worldly person, why should I be afraid of pain?" Hua Tuo hurriedly said, "But the general is also a flesh and blood body!"
Guan Yu said, "I Mr. Wen once healed a knife wound for Dongwu Zhoutai, and his injuries were worse than mine?" Hua Tuo thought for a moment and said, "Yes, General Zhou of Eastern Wu suffered dozens of knife wounds, and his condition was very miserable, but the wounds were not poisonous, only need to apply medicine to nourish, they can heal themselves, and there is no pain in cutting flesh and scraping bones!" Guan Yu said, "Mr. Hua Tuo, I have been fighting horses all my life, and I regard death as a homecoming, so why should I be afraid of this pain of scraping bones?" Besides, Sir is the arm that saved me, I can bear it, while my wine is not gone, please Sir boldly move!" Hua Tuo nodded helplessly, washed his hands again, put the knife in boiling water and boiled for a while, Guan Yu while drinking and playing chess on the side, while stretching out his arm to let Hua Tuo cut open, Guan Yu's right arm was dripping with blood, his face was sweating, the chess pieces in his hand fell, he looked at Hua Tuo, showed some smiles, turned back, picked up the fallen pieces, continued to play chess, Hua Tuo scraped bones, Guan Yu drank, the officials under him were anxiously waiting, Guan Yu played chess and laughed, and drank wine, at this time, Hua Tuo had already applied the medicine and bandaged it. Hua Tuo said, "General, you have finished curing!" Guan Yu immediately looked up and asked, "Huh?" So fast?" Guan Yu's officials and courtiers all came to see him, but Hua Tuo fainted, and Guan Yu immediately gave Hua Tuo a sip of water: "Mr. Hua Tuo, Mr. Hua Tuo..." Hua Tuo woke up and said: "General, I have been practicing medicine all my life, and I have treated tens of millions of people, and I have never seen a person like a general!" The general is really a god!" Guan Yu said, "Sir, I have been fighting all my life, but I can only endure pain a little, how can I compare to Mr. Magic, and come back to life from the dead, which is admirable!"
Hua Tuo hurriedly said, "Small skills, He Foot Daoya, He Foot Daoya, the general's spirit is rare in the world!" Hey, Hua Tuo can get to know the general, he has to treat the general's wounds, and he really doesn't deserve to practice medicine for a lifetime!" Guan Yu said, "Sir has passed the prize!" The two laughed. At this time, Guan Yu felt that his right arm was much better: "Huh? Wow! This arm has been stretched out and bent freely, and there is no pain, oh, sir, the real god doctor also!" Hua Tuo hurriedly said, "How dare you, general, although the arrow poison is removed, it still needs to be cultivated for a hundred days, and do not get angry before you can recover!" I leave a sticker of medicine, please apply it to the army. Guan Yu took the medicine: "Thank you sir!" When Hua Tuo was leaving, Guan Yu took some gold and said to Hua Tuo: "Guan Yu knows very well that Mr. Hua Tuo is not a gold person, but he only has a little Sichuan capital, talks about sending thanks, and has no other intentions, and hopes that Mr. Hua Tuo will accept it!" Hua Tuo asked, "What does this mean?" Guan Yu said, "Sir...", Hua Tuo stopped Guan Yu's words and said, "General Jiuwen is a hero and loyal soldier in the world, and I deliberately came from afar to heal the general's wounds. Knowing the general, the rest of the wish is enough, this thing can never be received! General Precious, gentlemen, farewell!" Saying, Hua Tuo got on the boat and left, Guan Yu shouted: "Sir...," but Hua Tuo has already gone far, Guan Yu arched his hand and sighed: "Mr. Magic, benefit Cangsheng, sir, please take care of yourself!"
