Zhu Danxi made significant contributions to the understanding of hernia (Shan), and his clinical prescriptions primarily focused on supporting Yuan Qi (Primal Qi). Regrettably, due to misfortune, his handwritten manuscripts were not transmitted, and those that circulated in the world were edited, added to, and continued by ignorant quacks, resulting in numerous errors and fallacies. The book *Zuan Yao* is particularly rife with such mistakes. All of Zhu Danxi's superior insights have been deleted, which is truly hateful. Taking the category of hernia as an example, it begins by stating: "Treatment focuses specifically on the Liver Meridian, and many cases are caused by Kidney Deficiency." The Liver is the child of the Kidney, and the anterior orifice is the opening of the Kidney. If one wishes to tonify the Liver, how can one neglect its mother organ? However, laypeople adhere to the theory that "the Liver has no tonification method," and upon encountering a case of hernia, they invariably diagnose it as Liver Excess, overusing draining and attacking methods, leading to many deaths. The current *Zuan Yao* does not record any tonification methods at all. Physicians of the time, lacking correct insight and having no other books for reference, inevitably make mistakes.

According to Zhu Danxi: Hernia can arise from deficiency; in such cases, the pulse is not deeply tight but rather wide and forceless. One should use Ren Shen (Ginseng) and Bai Zhu (Atractylodes Macrocephala Rhizome) as the sovereign drugs, assisted by herbs that promote circulation and drainage. How could he have blocked tonification methods? Zhang Zhongjing treated cold hernia with abdominal pain, accompanied by hypochondriac pain and internal tension, using Dang Gui Sheng Jiang Yang Rou Tang (Angelica Sinensis, Ginger, and Mutton Decoction). *Bencao Yan Yi* states that it is effective without exception; is this not evidence of the effect of tonifying the Liver? In my own practice, when treating patients suffering from critical conditions where Qi rushes upward to the chest and heart, I administer Ba Wei Wan (Eight-Ingredient Pill with Rehmannia) and see immediate results; this is another verification of tonifying the Kidney. Furthermore, in cases of constipation, one should promote bowel movement. For instance, Xu Shuwei and Luo Qianfu both used Yuan Hua (Genkwa Flower). Yet, *Zuan Yao* claims: "If it does not involve the Kidney Meridian, Wu Ling San (Five-Ingredient Powder with Poria) should not be used." It also states: "Hernia should not be treated with purgatives," implying that Yuan Hua should not be used. The herbs listed in the book are merely a few blood-breaking agents, mixed arbitrarily between bitter and acrid, cold and hot. They neither tonify the True Yin of the Liver and Kidney nor facilitate the free flow of the two lower orifices to allow pathogenic factors to exit. Instead, they silently deplete Qi, driving the patient toward danger day by day without their awareness. Is this not absurd?

There are seven types of hernia, and treatment must distinguish between them. Regarding deficiency, excess, cold, and heat, one should not rigidly adhere to warm tonification. Nor should one overuse herbs that break Qi. Zhang Jingyue has discussed this in detail.
