心者君主之官。神明出焉。
人身知觉运动。无一不本于心。故百体皆为之臣而心为君主也。西医言人心。只是顽然一物。不能司知觉运动。其

肺者相傅之官。制节出焉。
心为君主。肺在心外。以辅相之心火恐其大过。则肺有清气以保护之。如师傅之辅助其君也。故称相傅之官。究其

此即内经肺为相傅之义。但中国不名炭气。只名浊气也。心火太过。则气有余而上逆下注。心火不足。则下泄。上为饮

西医言苦胆汁。乃肝血所生中国旧说。皆谓胆司相火。乃肝木所生之气。究之有是气。乃有是汁。二说原不相悖。
惟西医言人之惧与不惧。不关于胆。而又不能另指一所。实未知胆为中正之官故也。盖以汁论。则胆汁多者。其人不惧。

故主断。

The term "Guan" (Minister/Official) refers to the affairs one is in charge of. When there is no disease, each organ performs its duties effectively; when disease occurs, it loses its specific function.
The Heart is the Sovereign Official, from which Shen (Spirit/Mind) emerges.
All perception and movement in the human body originate from the Heart. Therefore, all parts of the body act as ministers subject to the Heart, making the Heart the Sovereign. Western medicine regards the heart merely as a dull muscle incapable of governing perception and movement. It claims that perception and movement are entirely governed by the brain marrow. For instance, if the brain marrow of a rabbit is removed and the nerves at the back of the brain are excised, the body shrinks; this indicates that the nerves at the back of the brain govern movement. If the nerves at the front of the brain are excised, the rabbit cries out; this indicates that the nerves at the front of the brain govern perception. Applying this to humans, the logic holds true. However, I argue that this Western view is incorrect. Any minor injury to the skin or plucking of a hair causes pain, shrinking, or crying out in humans; why must brain nerves be excised for such reactions to occur? It seems Western medicine knows of the brain marrow but does not understand what marrow truly is. The *Huangdi Neijing* (Yellow Emperor's Inner Canon) states: "The Kidney governs bone and produces marrow," and marrow is generated from Jing (Essence). The Kidney and Heart originally function mutually. The nerves of the marrow connect to the Heart; this represents Kidney Qi ascending to interact with the Heart, forming an image similar to Kan Water (☵) contained within Li Fire (☲), thereby enabling the governance of Shen. For details, see the annotation on "Heart Stores Shen." Even regarding the nerve at the back of the brain mentioned by Westerners, if excised, the rabbit would not cry out because that nerve does not connect to the Heart. Westerners also state that brain nerves connect to the Heart; these must be the anterior brain nerves governing perception. Because they connect to the Heart, they govern perception; thus, the organ governing perception remains the Heart itself. If perception were governed solely by the Brain, why would excising the brain nerves connecting to the Heart result in no crying out? Even accepting their premise, their fallacy becomes self-evident without debate. Essentially, when Kidney Qi is sufficient, Marrow is sufficient. The nerves of the Marrow enter the Heart, using Kidney Water to balance Heart Fire. With True Essence contained internally, True Light radiates externally, and Shen emerges. The Heart belongs to Fire and emits light; Marrow belongs to Kidney Water and can gather light. When Shen-Qi ascends to the brain marrow, light and Qi illuminate each other, allowing clear understanding of things. Referencing the annotation on "Kidney Stores Zhi (Will)" clarifies this further.
The Lung is the Minister of Instruction, from which regulation and control emerge.
The Heart is the Sovereign, and the Lung is outside the Heart, assisting the Heart Fire to prevent excess. The Lung provides clear Qi to protect it, much like a tutor assisting a ruler. Hence, it is called the Minister of Instruction. Analyzing its mechanism: blood returns to the Lung, where Lung Qi blows upon it, expelling turbid Qi from the blood. The blood then turns red again and returns to the Heart. In the *Neijing*, this describes the convergence of Ying (Nutritive) Blood and Wei (Defensive) Qi in the Lung, which constitutes the duty of the Minister of Instruction. Western medicine states: returning blood enters the Lung, carbon dioxide (referred to as "carbon gas") is expelled, the purple color fades turning into red blood, which then returns to the Heart. The Lung acts as a filter for blood waste. This aligns with the *Neijing*'s concept of the Lung as the Minister of Instruction. The difference lies only in terminology: Chinese medicine calls it "turbid Qi" rather than "carbon gas." If Heart Fire is excessive, Qi surges upward and downward; if insufficient, it leaks downward. Upward manifestations include fluid retention and coughing, all due to a lack of regulatory control. Only when the Lung restrains Heart Fire from being excessive and regulates it from being deficient will the Qi above and below function harmoniously.
The Liver is the General Official, from which strategy and deliberation emerge.
In the body, Yin governs stillness, providing stability; Yang governs movement, providing action. The Liver belongs to the Jueyin channel, representing the extreme of Yin. Its nature is resilient and stable. Jueyin reveals Shaoyang; as Yin reaches its end, Yang is born. Gallbladder Fire resides within the Liver, meaning Yang is contained within Yin. The activation of Yang enables action, giving rise to strategy and deliberation. Thus, it is called the General Official. Consequently, those with stagnant Liver Qi may act recklessly, while those with deficient Liver Qi often feel fearful and timid.
The Gallbladder is the Official of Uprightness, from which decision-making emerges.
Western medicine claims bitter bile is produced from Liver Blood. Traditional Chinese Medicine (TCM) asserts that the Gallbladder governs Xiang Huo (Ministerial Fire), which is the Qi generated by Liver Wood. Upon investigation, having this Qi results in having this fluid; the two views do not contradict. However, Western medicine denies that fear relates to the Gallbladder and cannot identify another organ responsible, failing to recognize the Gallbladder as the Official of Uprightness. From the perspective of bile, those with abundant bile are not fearful. From the perspective of Qi, those with vigorous Gallbladder Fire are not fearful. Excess leads to deviation from the mean, resulting in loss of uprightness and aggressive behavior. Deficiency leads to timidity, also deviating from uprightness. When Gallbladder Qi is neither too rigid nor too soft, it achieves uprightness, enabling decisive judgment. Combining Liver and Gallbladder: Liver Yang is hidden within Yin, governing strategy; Gallbladder Yang emerges from Yin, governing decision.
The Pericardium (Shanzhong) is the Envoy Official, from which joy and pleasure emerge.
"Shanzhong" refers to the diaphragm in the chest, connected around the ribs and spine, blocking turbid Qi. While the diaphragm is named Shanzhong, the organ residing within it is the Pericardium. Old annotations confused the diaphragm with Shanzhong, failing to realize the diaphragm is merely a large membrane in the Upper Jiao that blocks turbid Qi and cannot replace the Heart in disseminating transformation, hence cannot be the Envoy Official. The Pericardium, however, assists the Heart in issuing commands. Residing within the Shanzhong diaphragm, it is named Shanzhong. It belongs to Xiang Huo and governs Blood. Using Blood to nourish Fire ensures harmony without烈 (intensity), thus governing joy. Depression arises when Pericardium Fire is blocked; excessive joy arises when Pericardium Fire is too strong. Western medicine notes a membrane wrapping half of the heart, referring to the Pericardium, but fails to understand its specific functions.
The Spleen and Stomach are the Granary Officials, from which the Five Flavors emerge.
While other organs have individual titles, the Spleen and Stomach share one title. Why? The Stomach receives grain, and the Spleen transforms it. Together, they achieve success. Thus, they are collectively called the Granary Officials, responsible for digesting and absorbing the five grains. "Five Flavors emerge" means that once food enters the Stomach, it transforms into fluids. Through the fatty membranes of the Spleen, these nutrients disperse to the five Zang organs. "Emerging" refers to reaching the various organs via Ying and Wei Qi. If the Stomach fails to receive grain, flavors do not enter; the Stomach, belonging to Yang, requires drying methods. If the Spleen fails to transform grain, flavors do not reach the organs; the Spleen, belonging to Yin, requires nourishing methods.
The Small Intestine is the Receiving Official, from which transformation emerges.
"Cheng" (Receive/Hold) implies storage. The Small Intestine connects to the Stomach above. All food received by the Stomach is stored in the Small Intestine. Western medicine describes the Small Intestine as interconnected by fatty membranes containing capillaries. Bile from the Gallbladder injects into the intestines via capillaries to digest food; sweet pancreatic juice from the Spleen also injects into the Small Intestine. Food is transformed in the Small Intestine, and the refined essence exits through the membranes to reach various organs. Hence, "transformation emerges." Wang Qingren in *Yi Lin Gai Cuo* identified the tissue attached to the Small Intestine as "chicken crest oil," naming it Qifu, believing it stores Yuan Qi and aids digestion. However, he ignored the *Neijing*'s explicit statement that the Small Intestine governs transformation via Qi dynamics. The fatty membrane attached to the Small Intestine constitutes the Middle Jiao, associated with the Spleen. The Small Intestine is also the Fu organ of the Heart. The pathway connects via capillaries in the membrane, crossing the diaphragm to the Pericardium, and finally to the Heart. Heat lingering in the Small Intestine from the Heart prevents proper transformation, leading to dysentery or strangury. Insufficient Spleen Yin hinders the Middle Jiao's ability to receive food, causing constipation. Insufficient Sanjiao Xiang Huo fails to warm and transform water and grain, causing loose stools. Western medicine's "small intestine inflammation" corresponds to TCM conditions like diarrhea, dysentery, and intestinal abscesses. Recent Chinese theories suggest water passes from the Small Intestine through the Lanmen (Gate) into the Bladder, a view Western medicine rejects. Water disperses from the Stomach into the mesenteric network (Lianwang), as detailed in the Sanjiao annotation. What the Small Intestine receives is food (Yin substance). Drinks primarily transform into Qi, while food primarily transforms into Blood. Food in the Small Intestine converts to liquid, rising via the mesentery to the Heart to generate Blood. Thus, the Small Intestine is the Fu organ of the Heart, serving as the source of material for the Heart.
The Large Intestine is the Transmission Official, from which change and excretion emerge.
"Change and excretion" refers to the process where substances from the Small Intestine arrive here,精华 (essence) is fully extracted, leaving waste to be expelled. The Large Intestine facilitates this transmission. It can transmit because it is the Fu organ of the Lung; descending Lung Qi enables transmission. Therefore, regulating bowel movements requires adjusting Lung Qi. See also the section on "Integration of Five Zang Organs."
The Kidney is the Official of Strength, from which skill and dexterity emerge.
Western medicine attributes intellect to brain marrow and physical strength to brain nerves, yet fails to define marrow. Marrow is generated from Kidney Essence. Sufficient Essence yields sufficient Marrow. Since Marrow fills the bones, sufficient Marrow strengthens bones, enabling great physical strength and talent. Essence generates Spirit (see "Heart Stores Shen"). Sufficient Essence and strong Spirit lead to skillfulness. Insufficient Marrow weakens strength; insufficient Essence limits wisdom. Western medicine discusses marrow extensively but lacks treatment methods because it ignores that Marrow is generated by the Kidney. Modern Chinese doctors, knowing only the Kidney and ignoring Marrow, are mocked by Westerners. They fail to realize that ancient sages in the *Neijing* already discussed Marrow Sea (*Sui Hai Lun*) and Bone Emptiness (*Gu Kong Lun*), integrating Kidney and Marrow theory. Ancient sages are indeed unparalleled.
The Sanjiao (Triple Burner) is the Official of Ditches, from which water pathways emerge.
"Jiao" (ancient form: 膲) refers to the membranes facilitating water flow. Modern physicians incorrectly believe water seeps into the Bladder only after passing the lower opening of the Small Intestine. Both *Yi Lin Gai Cuo* and Western medicine ridicule this. Since the Tang Dynasty, the nature of Sanjiao has been misunderstood. Western medicine states: water ingested enters the Stomach, where capillaries absorb it, distributing it through membranes to the mesenteric fat (Lianwang), then into the Bladder. This "mesenteric network" includes the diaphragm, abdominal fat, and all body membranes. These membranes connect to the Bladder, allowing water to渗 (seep) in. This is the ancient Sanjiao, the Official of Ditches, governing water pathways. The root of Sanjiao lies between the two Kidneys, where a strip of membrane runs along the spine, named Mingmen (Gate of Life), the origin of Sanjiao. From here, plate fat extends, connecting to the chest diaphragm, ascending through the chest to the Pericardium, linking to the Lung system up to the throat. Outwardly, it distributes to the interstices of the hands, arms, and chest, constituting the Upper Jiao. From plate fat to chicken crest oil attaching to the Small Intestine, outwardly to the waist and abdomen interstices, constitutes the Middle Jiao. From plate fat to net oil connecting posteriorly to the Large Intestine and anteriorly to the Bladder (with the uterus in between), outwardly to the buttocks, calves, and lower abdomen interstices, constitutes the Lower Jiao. Water drunk by humans flows via Sanjiao to the Bladder; if Sanjiao is unobstructed, water flows freely. If Sanjiao is obstructed, water pathways close, causing edema. Western medicine understands the morphology of the mesenteric network but does not name it Sanjiao, nor does it know its origin or Qi dynamics.
The Bladder is the Official of the Prefecture, storing Jin Ye (Body Fluids); Qi transformation allows excretion.
All dietary water enters the Bladder. Like a lake or island, the Bladder is the "Prefecture." People know the Bladder governs urination but ignore that water entering the Bladder transforms into Qi, ascending to become Jin Ye. The remaining residue descends as urine. "Qi transformation allows excretion" refers to the emergence of Jin Ye, not just urine. The concept of "Qi transformation" has been misunderstood since the Tang Dynasty. I explain in detail: Fire interacting with Water generates Qi. Observing Western methods of boiling water to produce steam confirms this interaction. How do Fire and Water interact in the body? The Heart governs Fire. Air inhaled through the nose is Heavenly Yang, also belonging to Fire. Western medicine states air enters the nose, goes to the Lung, passes the Heart system, follows the spine to the Kidney system, then to the mesentery, reaching below the umbilicus. Tracing this path reveals inhaled air is Heavenly Yang (Fire). Passing the Heart system draws Heart Fire down to the Qi Sea (below the umbilicus), also known as the Bao Gong (Uterus) in women. The *Neijing* states: "The Bladder is the chamber of the Bao." The Bao is a large fatty cavity capable of expansion and contraction, larger than the Bladder. Separated by a thin layer, it connects via capillaries to the Bladder. Heavenly Yang combined with Heart Fire descends to the Bao, steaming Bladder water into Qi, analogous to boiling water. This Qi penetrates the Bladder into the Bao, ascends alongside the umbilicus, crosses the diaphragm into the Lung, and exits via mouth and nose. Condensing on cold surfaces, it forms dew; within the mouth and organs, it becomes Jin Ye. Exiting via the nose is obvious. Exiting via skin pores warms the skin and moistens muscles as sweat. This is "Qi transformation allowing Jin Ye to emerge." Elderly people have more urine because less Qi is transformed, leaving more water quality. Young adults have less urine because more Qi is transformed. Western medicine describes inhalation to the umbilicus but omits the exhalation path, assuming it retraces the entry route. This is incorrect. Exhalation ascends via Qichong point to the diaphragm and exits via the Lung. Western medicine views the diaphragm as aiding lung ventilation, missing that it is the exit path for Qi, not just an inspiratory aid. Inhalation enters via the spine, governed by the Du Mai (Governing Vessel); exhalation exits via the diaphragm, governed by the Ren Mai (Conception Vessel). Inhalation is Yang (Fire meeting Water); exhalation is Yin (Qi returning to Water). Respiratory circulation is a Daoist secret, often misunderstood by medical practitioners. Only the *Neijing* phrase "Qi transformation allows excretion" clearly explains this. If Fire is insufficient to steam Water, Jin Ye does not ascend, and Qi does not transform. If Water is insufficient to cool Fire, Jin Ye dries up, and urination ceases.
Regarding the integration of Zang and Fu organs mentioned earlier, only Five Zang and Six Fu were listed. This excerpt from *Lantai Midian* adds the Pericardium, creating Six Zang and Six Fu, completing the theory. The Kidney contains both Water and Fire; the Fire aspect is Mingmen. Thus, the previous section stated "Shaoyang belongs to the Kidney," indicating Sanjiao Xiang Huo originates from Mingmen. The Kidney connects to the Lung, representing Metal generating Water, with the Bladder as its Fu organ. It is said "thus dividing two Zang organs," meaning Kidney and Mingmen can be treated as two Zang organs pairing with the Sanjiao and Bladder as two Fu organs. The *Nanjing* assigns the Left Kidney and Right Mingmen, having its own rationale. Saying "Five Zang and Six Fu" highlights the essentials; saying "Six Zang and Six Fu" enumerates all components. Adding Mingmen creates Seven Zang and Six Fu, representing the odd numbers. Heaven and Earth follow patterns of odd and even numbers, varying intricately. Human organs reflect this, explaining why there are Extraordinary Vessels and oddities among the Zang and Fu organs.
