Apply medicine to the affected area, and after one night, the eyes returned to their original state, with no further illness or suffering. This incident is recorded in Yang's *Shanju Xin Hua* (New Tales from Mountain Living), stating that Nie personally told him about it, and the severed tongue was still preserved. Note: The Guanghui Si (Imperial Bureau of Hui Medicine) consisted of Hui physicians (Islamic doctors). Nie, who was under their jurisdiction, may have witnessed such a case, which is why he could treat it. It is a pity that Mr. Yuancheng at that time did not inquire about the cause of the disease.

Hemorrhagic syndromes are prone to occur in young individuals with weak constitutions, yet they are quite difficult to treat. Miu Zhongchun stated that there are three key principles for treatment: First, it is advisable to promote blood circulation rather than stop bleeding. Promoting circulation allows blood to flow within the meridians, and bleeding will cease naturally; forcibly stopping bleeding causes blood stasis and fever, making the condition increasingly entrenched. Second, it is advisable to nourish the Liver rather than attack it. Since blood is stored in the Liver, vomiting blood indicates that the Liver has lost its function of storing blood. Therefore, only by nourishing the Liver can Qi be harmonized and blood find its proper return; attacking the Liver leads to deficiency where it cannot store blood, resulting in even more severe bleeding. Third, it is advisable to regulate Qi rather than clear heat/fire. Excess Qi manifests as fire; when Qi flows smoothly, fire descends, and blood follows Qi, thus preventing overflow. If one attempts to clear fire, cold and cooling herbs must be used, which damages the Spleen and Stomach. Once the Spleen Qi is damaged, how can it continue to control blood and stabilize the collaterals? This argument is very clear, and scholars of Chinese medicine can certainly take this as a model. Ancients said that in treating hemorrhagic syndromes, ten out of ten patients die if given cold and cooling medicines, and ninety-nine out of a hundred die if given Tongbian (Child Urine). However, Tongbian can descend fire, nourish Yin, and eliminate stasis very rapidly. I believe that drinking one's own urine is better than drinking child urine, as it can be consumed conveniently without losing true Qi, and it encourages a bland diet while avoiding pungent and salty flavors. A bland diet also aids in the generation of new blood.

A physician relies on intuition (Yi/mental apprehension); only by understanding change can one effectively utilize herbal medicines. It is often seen that the same prescription yields different results—effective or ineffective—due to slight variations in dosage or the addition of a guiding herb. The weight and potency of herbs must be measured against the depth and superficiality of the disease, ensuring the medicinal force reaches the affected site appropriately; if it does not reach, there will be no efficacy. As for adding a single guiding herb, it may seem insignificant, but just as an army marching a thousand miles requires a guide, so too does treatment require direction. Emperor Huizong of Song ate ice in summer and subsequently suffered from Pi Xie (Spleen Deficiency Diarrhea). Imperial physicians prescribed medicines without effect, so he summoned Yang Jie for diagnosis. Yang Jie prescribed Dali Zhong Wan (Greatly Augmenting the Middle Pill). The Emperor said, "I have taken this many times." Yang Jie replied, "The cause of the illness was eating ice; I use ice to decoct the medicine, thereby treating the root cause of the disease." The patient recovered after taking it. This aligns with the classic saying: One must subdue the main pathogen and first address the etiology; although the beginning may be similar, the outcome differs.
