阴络腹行，阳络背行，缘督为治，支无不伸。
一人病脚 不能行，先生切脉后，即使解衣，点背数十处，相间一寸或五寸，从邪不能
当，言灸此各七壮，灸创愈，即能行也。后灸愈，灸处夹背一寸上下行，端直均调，如引绳
也。
按∶先生以四言为主要，知药所不及，乃易之以灸。人谓灸不难，得穴难。余谓得穴非
难，因有图可按，体格部位可稽也。惟病之应灸与否，又灸从何起，迄何止。有胆有识，斯
诚难耳。先生之享大名于后世也，即此胆与识为之基也。（孙思邈）
讳疾忌医，死。
酒之发酵，足伤肺翼，害肠胃，惟葛花可解。暨渎严昕与数人共候，先生适至，谓昕曰∶
“君身中佳否？”昕曰∶“无他。”先生曰∶“君有疾急见于面，毋多饮，多饮则不治。”与
以葛花粉令服之，昕不能信，复饮，归行数里，卒头眩堕自车，人扶之，辇回家，越宿死。
（孙思邈注）
乘虚御内，亡。
故督邮顿子献得病，已瘥，诣先生。先生为切其脉，曰∶“尚虚未得复，勿为劳事。御
内即死，临死当吐舌数寸。”其妻闻其病除，自百余里来省之，止宿交接，中间三日，病发，
一如先生言。
按∶肾水愈不足，相火愈妄动，故患虚损者，愈喜近女色。致女欲拒而不能，非腰痛如

阴络在腹部运行，阳络在背部运行，沿着督脉进行治疗，所有的支脉没有不能舒展的。
有一个人脚病导致无法行走，先生（华佗）切脉后，立即让人解开衣服，在背部点了数十个穴位，间距一寸或五寸，说邪气不能抵挡这些穴位，告知在这些穴位各灸七壮，等灸疮愈合后，就能行走了。后来治愈的案例中，灸处位于背部两侧，沿脊柱上下排列，端正笔直、均匀协调，像拉直的绳子一样。
按语：先生以四言歌诀为主要形式，知道药物所不及之处，便改用艾灸。人们说取穴不难，难的是找到正确的穴位。我认为找到穴位并不难，因为有图谱可以参照，体格部位可以考证。只有判断疾病是否适合艾灸，以及艾灸从何处开始、到哪里停止，这需要胆识，这才是真正的难点。先生之所以在后世享有大名，正是基于这种胆识。（孙思邈注）
讳疾忌医，导致死亡。
酒的发酵过程，足以损伤肺叶，危害肠胃，只有葛花可以解酒毒。严昕与几个人一起等候拜见先生，先生恰好来到，对严昕说：“你身体好吗？”严昕说：“没有其他毛病。”先生说：“你的面色显示出急症即将发作，不要多喝，喝多了就无法治疗了。”给他葛花粉让他服用，严昕不相信，又喝了酒，回家走了几里路，突然头晕目眩从车上摔下，被人扶起，用车子送回家，过夜后死亡。（孙思邈注）
乘虚行房，导致死亡。
所以督邮顿子献生病，已经痊愈，去拜访先生。先生为他切脉，说：“身体尚且虚弱，尚未恢复，不要做劳累的事情。如果行房就会死，临死前舌头会伸出数寸。”他的妻子听说他病好了，从百余里外赶来探望，住宿期间发生性行为，中间过了三天，病情发作，完全像先生所说的那样。
The Yin collaterals circulate in the abdomen, and the Yang collaterals circulate in the back. Treating along the Du Mai (Governing Vessel) ensures that all branch vessels can extend without obstruction.
A person suffered from a foot ailment and was unable to walk. After taking the pulse, Master Hua immediately instructed him to undress. He marked dozens of points on the back, spaced one or five cun apart, stating that the pathogenic factors could not withstand these points. He advised moxibustion of seven moxa cones at each point. Once the moxibustion wounds healed, the patient regained the ability to walk. In subsequent cured cases, the moxibustion sites were located on both sides of the back, arranged vertically with even spacing, straight and uniform like a plumb line.
Commentary: Master Hua primarily used four-character verses. Recognizing the limitations of herbal medicine, he substituted it with moxibustion. People say that locating acupoints is not difficult, but finding the correct ones is. I argue that locating acupoints is not difficult, as there are charts to refer to and anatomical landmarks to verify. The true difficulty lies in determining whether a disease is suitable for moxibustion, where to begin, and where to stop. This requires courage and insight, which is genuinely challenging. It is precisely this courage and insight that laid the foundation for Master Hua's great fame in later generations. (Sun Simiao)
Concealing illness and avoiding medical treatment leads to death.
The fermentation process of wine is sufficient to damage the lung lobes and harm the intestines and stomach; only Puerariae Flos (Kudzu Flower) can resolve alcohol toxicity. Yan Xin waited with several others to see the Master. The Master happened to arrive and asked Yan Xin, "How is your health?" Yan Xin replied, "I have no other ailments." The Master said, "Your facial appearance indicates an impending acute condition. Do not drink excessively; if you do, it will be incurable." He gave Yan Xin Puerariae Flos powder to take. Yan Xin did not believe him and drank more wine. Upon returning home and walking a few li, he suddenly experienced dizziness and fell from his carriage. Being helped up and transported home by cart, he died overnight. (Sun Simiao's Note)
Taking advantage of deficiency to engage in sexual intercourse leads to death.
Thus, Dun Zixian, a Duzhu (official title), fell ill and had already recovered when he visited the Master. The Master took his pulse and said, "Your body is still deficient and has not yet fully recovered. Do not engage in strenuous activities. If you engage in sexual intercourse, you will die. At the moment of death, your tongue will protrude several inches." His wife, hearing that his illness had cleared, traveled over a hundred li to visit him. They stayed overnight and engaged in sexual intercourse. Three days later, the illness recurred exactly as the Master had predicted.
Commentary: The more insufficient the Kidney Water becomes, the more recklessly the Ministerial Fire moves. Therefore, those suffering from deficiency depletion tend to desire proximity to women. This results in a situation where the woman wishes to refuse but cannot, accompanied by waist pain as severe as being cut,
