Domain Guide

When people speak of jingfang—classical formulas—the first things that usually come to mind are prescriptions such as Guizhi Tang, Mahuang Tang, Xiaochaihu Tang, or Sini Tang. Learning jingfang is therefore often understood as memorizing formula names, ingredients, and formula-pattern correspondences, and then gradually learning through clinical experience when each prescription should be used.

From the Five Flavors and Spacetime Coordinates to the Generative Rules of Classical Formulas

But one step deeper, the problem becomes much harder. Why were these formulas originally constructed in exactly this way? Why these herbs rather than others? Are sour, bitter, sweet, pungent, and salty merely sensory labels, or are they a language for operating on qi transformation in the body? Why does the same Five-Phase vocabulary sometimes say that sour enters the Liver, while elsewhere the Liver is supplemented with pungent and drained with sour? And why do rules for flavor change again under Sitian, Zaiquan, victory, restoration, host, and guest conditions?

The Jingfang domain is an attempt to recover this deeper layer of generative rules behind concrete prescriptions.

The sequence therefore does not begin from a famous formula. The Ancient Astronomical-Geometric Orbital Essence of the ‘Jing’ in Classical Formulas first asks what the word jing itself implies. The point is not to rush toward a modern physical mechanism, but to understand why the classical authors could imagine that formulas worthy of transmission should reflect some repeatedly stable “constant way.” When we look at an ancient formula, we should therefore ask not only how later physicians used it, but whether its composition contains rules that reappear across different passages and are more stable than individual experience.

Surprisingly, the first doorway into those rules is food rather than medicine. The Secret of the Sixteen-Character Dietary Formula and the Principle That Material Formation Determines Flavor starts from the classic scheme of grains, fruits, meats, and vegetables and shows how a vast material world could be compressed into the five flavors. The crucial shift is that flavor is not only what the tongue senses; it also becomes a way of describing the direction in which a substance may act after entering a living system. Jingfang can then be studied not as the memorization of hundreds of drugs, but as the composition of a small set of operational languages.

The difficulty begins immediately afterward. The Central-Earth Spatial Model of the Five Flavors and the Affinities of the Five Entrances presents sour entering the Liver, bitter entering the Heart, sweet entering the Spleen, pungent entering the Lung, and salty entering the Kidney as a spatial affinity organized around Earth at the center. “Entering” here first answers which zang position a flavor tends to relate to; it does not automatically mean that the flavor supplements that zang. The Bidirectional Temporal Control Model of the Heavenly Stems and Five Phases must therefore be read next, because classical medicine also uses the Five Phases in a temporal way. Once the problem shifts from space to time, the Five Phases describe growth, prosperity, decline, and directional change through a cycle.

From this point onward, two maps must remain distinct: the spatial model asks where something is located; the temporal model asks in which direction it is changing. If the two are collapsed into one, many rules of the five flavors appear contradictory.

Once the two coordinate systems are established, intervention can begin. Matrix Vectors of the Overcoming and Supporting Positions in the Spatial Model turns generating and overcoming relationships from a diagram to be memorized into reusable relations between an overcoming position and a supporting position. The question becomes whether treatment should directly restrain the abnormal side or support the side being suppressed. This is where Five-Phase relations begin to behave like operators rather than labels.

The temporal model is developed in The Prosperous–Ministering–Declining–Imprisoned–Dead Cycle of the Heavenly Stems and Five Phases in the Discourse on Zang Qi and the Seasons. The five zang are not assumed to remain at a fixed intensity but to move through phases of flourishing and decline. The Five Desires of the Five Zang and the Temporal Model’s Rules of Supplementation and Drainage then asks what direction a zang’s normal qi movement seeks, and what it means to move with or against that tendency. Rules such as “supplement the Liver with pungent, drain it with sour” can therefore be understood on a different layer from “sour enters the Liver”: the former concerns temporal regulation of qi movement, while the latter concerns spatial affinity. The Five-Distress Temporal Intervention Model of Relaxing, Urgency, Gathering, and Dispersing goes further by treating relaxing, urgency, gathering, dispersing, moistening, drying, discharging, and hardening as directional functional operators. Only at this point does the reader possess the basic vocabulary needed to enter the treatment language of the Zhizhen Yaodalun.

The scale then expands. The Ferris-Wheel Mechanism of Sitian and Zaiquan in the Rotation of the Six Qi establishes the positions of the Six Qi through the year—Sitian, Zaiquan, transformation in Heaven, governance on Earth. The important point is not the image of a Ferris wheel itself, but the idea that the same wind, fire, dampness, dryness, or cold may act differently depending on where it is positioned. Land, Phenology, and Flavor Bias under the Annual Rotation of Sitian carries that temporal background from climate into material formation: if plants and foods grow under different yearly climates, might even materials of the same class acquire a bias from the year in which they formed? Jingfang and dietary therapy thereby reconnect.

With position established, Six Qi × Seven Major Families of Motion compresses the many repeated appearances of the Six Qi into a role table: Where is this qi standing? Is it host or guest? Is it operating normally or gaining excessive advantage? Does suppression lead to a rebound? Has the original order been reversed? Before studying those disruptions, however, a normal baseline is required. Treatment of the Five-Phase Host Positions and the Temporal Sequence of the Three Yin and Three Yang Host Qi establishes the relatively constant host movement and host qi and, importantly, shows that the classics sometimes specify not only which flavor to use but the sequence of supplementation and drainage.

Only then do we enter the treatment matrix. The Therapeutic-Flavor Structure of Six-Qi Victory in the Sitian Position studies excessive Six-Qi influence in the upper Sitian position and the division of labor between primary flavor, assisting flavor, and later functional action. It shows how a Five-Phase rule may provide a baseline while position and the concrete nature of the qi modify that baseline. The Treatment Structure of the Six Qi in Zaiquan Excessively Invading the Interior moves the same Six Qi to the lower and internal Zaiquan position so that the reader can compare how the same name generates a different treatment structure when its location changes.

Position is not enough; power relations must also be represented. The Treatment Structure of Pathogenic Qi Counter-Victory on Earth and The Treatment Structure of Pathogenic Victory over Sitian show why counter-victory cannot be reduced to “identify the strongest pathogen and oppose it.” One must also know who should originally occupy the position and which side is being suppressed. In a single treatment rule, flavor and thermal nature may therefore be solving different layers of the problem. This makes it possible to decompose a formula into tasks instead of assigning the whole prescription one broad label such as “clearing heat” or “dispelling cold.”

The Treatment Structure of the Victory of the Six Qi then asks what happens when one qi becomes dominant, while The Treatment Structure of the Restoration of the Six Qi brings time directly into pathomechanism: after a biased victory, the system may produce a compensatory response. Restoration is therefore not simply another isolated pathogen; it is the next-state response to an earlier imbalance. Treatment begins to move from static “treat what is present now” toward a dynamic sequence of prior state, current state, and next state. The Treatment Structure of the Six Qi as Guest Qi finally isolates the host–guest relation itself: guest qi may be weak and suppressed by host qi, or excessive and take over the host position. By this point, “one qi equals one flavor” should no longer be conceivable as a fixed one-to-one rule.

On that basis, Guest-Qi Day Governance, Supplementation and Drainage, and the Source of the ‘Pungent + Sour Transform into Sweet’ Formula can introduce higher-order combinations such as pungent plus sour transforming into sweet, salty plus bitter into sour, sweet plus pungent into bitter, sour plus salty into pungent, and bitter plus sweet into salty. Whatever degree of validation these transformation rules ultimately receive, they point toward an essential research problem: formula construction cannot stop at asking what each flavor does independently; it must also ask whether multiple flavors form a new whole when they meet.

Most of the preceding articles operate within a single qi-transformation scenario. Introduction to the Sixty-Jiazi Dietary-Therapy Model of Generating and Completing Numbers in the Great Discourse on the Regular Order of the Six Origins abruptly widens the horizon to the sixty-year Jiazi cycle, combining stem-branch pairs, Sitian, Zaiquan, central movement, dietary recommendations, and numerical qi-transformation relationships into a long-cycle data structure. The generating/completing-number and Hetu relations should be treated as model hypotheses that still require textual and empirical testing, not as conclusions merely because numbers appear to match.

Only after traversing the entire sequence do we reach General Rule for Choosing the Spacetime Model of Heavenly Qi and Earthly Qi. This final article is not another formula to memorize; it asks how to choose a model. Under what conditions should we first read a passage through temporal supplementation/drainage and direction of qi movement, and when should we first use spatial affinity, overcoming positions, and supporting positions? A mature reader should not turn “Heavenly qi uses the temporal model; Earthly qi uses the spatial model” into another rigid rule. It is a high-level compression that must remain open to falsification by the text itself.

The real outcome of this domain is therefore not the memorization of twenty-two articles, but four capabilities: to turn the five flavors from static labels into operational language; to distinguish spatial position from temporal qi movement when the same Five-Phase symbol appears; to decompose a complex treatment clause into position × intrinsic qi × host/guest × victory/restoration × sequence × therapeutic flavor × thermal nature × functional action; and, most importantly, to move from rules back toward formulas.

At that point, classical prescriptions no longer appear only as precious finished products handed down for two thousand years. They begin to look like a therapeutic grammar produced by a highly compressed model of time, space, the five flavors, the Six Qi, and human qi transformation. Only when that grammar can reproduce classical formula choices across many passages—and explain its counterexamples—will we have moved closer to answering why jingfang were composed as they were.

What You Will Be Able to Do

After completing this domain, readers should be able to move from isolated terms toward traceable models, rules, and derivations, while distinguishing direct textual support from structural hypotheses still under investigation.
