Abstract

For centuries, traditional Chinese medicine has understood the human body primarily through the theories of Yin and Yang, the Five Elements, the Zang-Fu organs, the meridians, Qi, and blood. Modern medicine, by contrast, relies mainly on anatomy, physiology, biochemistry, and molecular biology to explain diseases and therapeutic mechanisms. However, the human body is not merely a living system composed of tissues, organs, and physiological functions; it is also a geometric structure characterized by specific forms, positions, orientations, proportions, symmetries, crossings, and spatial correspondences. Nevertheless, the possible existence of stable morphological correspondences and spatial relationships among different parts of the human body has yet to be systematically investigated.

The discovery and clinical application of the 3C technique demonstrate that geometric reasoning can be used to identify correspondences between distant regions of the human body and subsequently verify them in clinical practice. The fundamental research approach is as follows: first, a hypothesis is formulated on the basis of the body’s morphology and spatial structure, from which potentially corresponding regions are deduced; these regions are then located, stimulated, compared, and clinically verified. Numerous clinical observations suggest that precise laws of geometric correspondence do indeed exist between certain parts of the human body. This concept may be summarized by the statement: “Form is information; position carries meaning.” Therefore, establishing and developing research on Human Body Geometry in traditional Chinese medicine is of major importance for expanding the theoretical framework of Chinese medicine, revealing the principles underlying acupuncture analgesia, and improving the standardization and precision of clinical treatment.

I. Medicine Without Geometry May Be Incomplete

Why can we say that “medicine without geometry is incomplete”?

Geometry is an important branch of mathematics. It studies the form, position, orientation, distance, proportion, symmetry, and spatial relationships of objects. Mathematics is not merely a computational tool; it is also a method for discovering laws, constructing models, and conducting logical reasoning. Throughout the development of modern physics, many major theories were first formulated through mathematical deduction and only later confirmed by observation or experimentation. In other words, scientific discoveries do not always begin with the repeated accumulation of empirical observations. They may also originate from logical relationships, leading first to the formulation of a testable hypothesis and then to its confirmation or refutation by evidence.

For example, in plane geometry, the sum of the interior angles of a triangle is equal to 180 degrees. On a spherical surface, however, the sum of the interior angles of a triangle formed by geodesic lines may be greater than 180 degrees. When measurements are conducted over large areas of the Earth’s surface, this difference can reveal the curvature of that surface. Humanity’s understanding of the Earth’s shape developed over a long historical period, and geometric measurements provided important evidence for recognizing and confirming its spherical form. This example demonstrates that small but consistent spatial differences may contain essential information about the overall shape of a structure.

The human body is likewise a complex three-dimensional structure. It exhibits left-right symmetry, upper-lower organization, relationships between flexion and extension, medial and lateral aspects, anterior and posterior regions, diagonal crossings, proportional similarities, relationships among different local regions, and relationships between individual regions and the body as a whole. If medicine studies only the tissues composing the human body and the physiological functions of its organs, without systematically examining the spatial correspondences among its different regions, our understanding of the human body remains incomplete.

Anatomy tells us “what the human body is made of”; physiology studies “how it functions”; pathology explains “why disease develops”; and Human Body Geometry seeks to investigate more specifically “what spatial relationships exist among the different forms and positions of the body.” It is not intended to replace existing medical disciplines, but rather to complement and expand our system of knowledge about the human body.

II. The 3C Technique Originated from Geometric Logical Reasoning

The 3C technique—“Crossing and Corporeal Correspondence”—was not developed from the established therapeutic indications of any particular traditional acupuncture point. It arose from geometric reflection prompted by a clinical observation.

During one treatment, I used the Guguan, Muguan, and Zhongguan points of Master Tung’s acupuncture, located on the palm near the wrist, to treat a patient suffering from pain in the contralateral calcaneus. The effect was extremely rapid and pronounced. This observation led me to ask the following question: why did stimulation of this particular region produce such a remarkable effect on pain in the opposite heel?

If we merely follow traditional clinical experience, we might simply remember that “a certain point can treat heel pain” and continue to use it in similar cases. However, this would remain an isolated empirical observation, unable to explain why the treatment is effective or to provide a basis for deducing further principles.

Observation of human morphology reveals that when a person supports the body on all four limbs, the palmar region near the wrist and the heel display certain morphological similarities and occupy comparable functional positions. This led to a geometric hypothesis: could a specific and stable correspondence exist between body regions with similar forms?

If this hypothesis were correct, the left thumb should correspond to the right great toe, the left index finger to the right second toe, and the remaining fingers should likewise correspond sequentially to the other toes. This was no longer a matter of memorizing the therapeutic indication of a particular acupuncture point, but rather of making a logical deduction based on the morphology and spatial organization of the human body.

While I was considering this question, a nurse nearby mentioned that she had pain on the dorsal aspect of her left thumb. Following the reasoning described above, I immediately performed horizontal needling on the dorsal aspect of her right great toe. The pain disappeared at once, with a speed comparable to that previously observed in the treatment of heel pain. Subsequently, the correspondences between the fingers and toes, between the metacarpals and metatarsals, and among other body regions were progressively verified in clinical practice.

The early discovery process of the 3C technique therefore followed a very clear methodological sequence:

A clinical observation raises a question — observation of human morphology — formulation of a geometric hypothesis — deduction of corresponding regions — clinical verification — correction and establishment of correspondence principles.

This is a research method in which geometric logical reasoning precedes verification through clinical experimentation.

III. Form Is Information; Position Carries Meaning

In research on the 3C technique, therapeutic efficacy depends not only on the limb or bone selected, but may also be related to the exact location of the stimulation point.

For example, one of my friends experienced pain between the fourth and fifth metacarpals. According to the correspondence between the hand and foot, the theoretically corresponding region should have been located between the fourth and fifth metatarsals on the opposite side. To determine whether this correspondence required precise localization, I first deliberately applied stimulation between the third and fourth metatarsals, but no significant effect was observed. I then added a stimulation point between the fourth and fifth metatarsals, and the pain disappeared immediately.

This comparison indicates that the therapeutic effect probably did not result from stimulating an arbitrary location on the foot, but was closely related to the accuracy of the corresponding position. Although the spaces between the third and fourth metatarsals and between the fourth and fifth metatarsals are very close to each other, they represent different spatial positions. Once the location deviates from the precise point, the correspondence may no longer be valid.

Similar phenomena have also been observed between specific bony landmarks. Geometric reasoning based on the structure of the human body suggests a correspondence between the tip of the radial styloid process and the tip of the contralateral lateral malleolus. Clinical practice indicates not only that this correspondence exists, but also that it is extremely precise. If the stimulation point deviates from the exact position of the bony landmark—even by only a few millimetres—the effect may be markedly reduced or disappear completely. This demonstrates that, in certain bodily correspondences, the “region” alone is not important; orientation and exact location are equally essential. This observation led me to establish the principle of corporeal correspondence to ensure precise localization.

We therefore propose the following statement: Form is information; position carries meaning.

This statement is not merely an abstract rhetorical expression, but rather a structuralist perspective that can be tested through clinical comparison. The morphology, organization, and spatial position of the human body may convey specific information. The therapeutic significance of a body region may derive not only from its association with a particular meridian, but, more importantly, from the specific geometric position it occupies within the body’s overall structure.

From this perspective, the human body is not simply an assembly of numerous isolated regions, but an integrated structure characterized by hierarchy, order, and relationships of correspondence. A change in a local position may alter the significance of that region within the whole, while different regions may be connected through structural patterns of similarity, symmetry, crossing, or inversion.

IV. Bodily Correspondences Must Be Systematically Discovered Through Geometric Reasoning

When relying exclusively on clinical experience, one may accidentally discover that a particular acupuncture point can treat pain located in a distant region. However, it is difficult to rapidly deduce an entire system from a single empirical observation.

For example, when a region of the hand can be used to treat pain in the foot, many further questions must be answered:

• How does the palm of the hand correspond to the sole of the foot?

• How does the dorsum of the hand correspond to the dorsum of the foot?

• Does the thumb correspond to the great toe, the index finger to the second toe, and so forth?

• What relationship exists between the radial and fibular sides, and between the ulnar and tibial sides?

• Should the proximal and distal parts be inverted?

• Is the correspondence between the left and right sides ipsilateral or crossed?

• How can the flexor and extensor aspects, as well as the medial and lateral aspects, be precisely converted?

• How should bony prominences, articular margins, and interosseous spaces be located?

• Do the neck, trunk, and limbs follow exactly the same laws of correspondence?

These questions cannot be fully answered merely by memorizing the traditional therapeutic indications of acupuncture points. They must be analyzed using geometric concepts such as similarity, symmetry, proportion, projection, rotation, inversion, and crossing.

Certain “inversion” principles of the 3C technique were first formulated through logical reasoning and subsequently verified in clinical practice. The discovery of crossed relationships in the neck also resulted from combining geometric analysis with clinical practice. Through this method, a clinical observation can be transformed into a hypothesis; that hypothesis can then be used to deduce a series of new correspondences, each of which can be subjected to clinical verification.

If a deduced position proves effective, it supports the original hypothesis. If it does not, it is necessary to determine whether an error has been made in the level of correspondence, orientation, bodily aspect, or method of inversion, and then to correct the model accordingly. This approach enables acupuncture research in traditional Chinese medicine to progress beyond the mere accumulation of empirical observations and move toward a structured methodological pathway: formulate a hypothesis — verify it — refine the principles — establish a system.

Without mathematical and geometric reasoning, and by relying solely on fragmented clinical experience, it is extremely difficult to establish a pain-relief technique that is rigorous, precise, effective, and systematic.

V. Human Body Geometry in Traditional Chinese Medicine Can Provide a New Explanatory Framework for Acupuncture

The mechanisms of action of acupuncture have long been explained primarily through modern anatomy, physiology, neuroscience, biochemistry, and biomechanics. Such research is extremely important and has revealed many biological processes that may be involved in the effects of acupuncture, including neuromodulation, endogenous analgesia, local tissue responses, and central nervous system integration.

However, these theories may not fully explain every clinical phenomenon. In particular, they have difficulty answering the following questions on their own: why can a precise point located far from the painful region rapidly influence pain? Why can a slight displacement of the stimulation point result in a marked reduction in therapeutic efficacy? Why do similar forms, symmetrical positions, crossed structures, and specific bony landmarks exhibit relatively stable clinical relationships?

The fact that current theories cannot yet fully explain a phenomenon does not mean that the phenomenon does not exist. Likewise, it does not justify denying the value of existing medicine. A more rational approach is to develop a new research perspective and use rigorous methods to determine whether these phenomena are real, stable, and reproducible.

Human Body Geometry in traditional Chinese medicine is not primarily concerned with determining whether a stimulation point contains a particular substance. Instead, it focuses on the position that the point occupies within the overall structure of the human body and on its morphological and spatial relationships with the painful region. Its subject of investigation is therefore the “relationship” itself, including:

• correspondences between self-similar forms;

• transformations between dissimilar forms;

• crossings between the left and right sides;

• projections between the upper and lower parts of the body;

• inversions between proximal and distal regions;

• localization relationships between flexor and extensor aspects, as well as between medial and lateral aspects;

• spatial relationships among bony landmarks, joints, and soft tissues;

• laws of correspondence between local structures and the human body as a whole.

This field of research can offer acupuncture a third perspective, distinct from meridian-based explanations and biomedical interpretations: understanding the human body through its morphology, spatial positions, and structural relationships.

VI. The Practical Significance of Developing Research on Human Body Geometry

1. Promoting Theoretical Innovation in Traditional Chinese Medicine

Human Body Geometry in traditional Chinese medicine does not merely consist of assigning new therapeutic indications to traditional acupuncture points. It seeks to determine whether the human body itself contains a set of spatial principles that can be logically deduced and clinically verified. It may therefore broaden the traditional Chinese medical understanding of the body as an integrated whole, enabling the concept that “the human body is an organic whole” to progress beyond a philosophical description and become a system of structural relationships that can be located, measured, compared, and verified.

2. Improving the Precision of Acupuncture Treatment

Traditional acupuncture localization is generally based on acupuncture points and meridians. The 3C technique places additional emphasis on the precise correspondence between the painful point and the corresponding point, taking into account their morphology, orientation, and exact location. Clarifying these relationships may help reduce blind needling attempts and the selection of excessively broad treatment regions, allowing treatment to progress from the “approximate selection of a region” to “precise localization.”

3. Improving the Reproducibility of Therapeutic Effects

If a therapeutic result can be achieved only by a small number of physicians relying on personal intuition, the method will be difficult to disseminate. Only by translating the laws of bodily correspondence into clearly defined standards for localization, orientation, and clinical practice can other researchers and clinicians reproduce and verify them. Human Body Geometry in traditional Chinese medicine may therefore help transform individual experience into shared knowledge that can be taught, reproduced, and tested.

4. Promoting the Standardization and Normalization of Acupuncture

The geometric relationships of the human body can be described through bony landmarks, proportional measurements, spatial orientations, and levels of correspondence. They can also be represented using anthropometry, three-dimensional modelling, and computer technology. This can facilitate the establishment of standardized terminology, uniform localization methods, standardized operating procedures, and common criteria for evaluating therapeutic outcomes, while reducing differences among practitioners.

5. Establishing a Foundation for Artificial Intelligence and Digital Acupuncture

If the laws of bodily correspondence can be mathematically expressed and modelled, they can be converted into rules that computers are able to interpret. In the future, three-dimensional human body models, medical imaging, anthropometry, and artificial intelligence could be used to automatically calculate possible corresponding points based on the location of pain. Acupuncture-point localization could thus gradually progress from empirical judgement toward digitally assisted decision-making.

6. Promoting In-Depth Dialogue Between Traditional Chinese Medicine and Modern Science

The modernization of traditional Chinese medicine should not be limited to reinterpreting ancient concepts using the terminology of modern medicine. Traditional Chinese medicine should also develop its own research methods for formulating questions, establishing hypotheses, and subjecting them to verification. Combining geometric reasoning with clinical experimentation provides a practical research pathway for traditional Chinese medicine. This approach preserves its emphasis on the interconnectedness of the human body as a whole while introducing scientific methods such as mathematical reasoning, comparative verification, and repeated experimentation.

VII. Establishing Human Body Geometry in Traditional Chinese Medicine Requires a Rigorous Research Methodology

For Human Body Geometry in traditional Chinese medicine to develop into a genuine academic discipline, it cannot rely solely on successful clinical cases. It is also necessary to investigate whether possibilities other than the observed geometric correspondences may be involved. Future research should adopt more rigorous methods, including the following:

First, clearly define each type of correspondence, its orientation, and its scope of application, and establish standardized terminology.

Second, accurately record both the stimulation point and the painful point, specifying the left or right side; the anterior or posterior, medial or lateral aspect; flexion or extension; bony landmarks; and distances.

Third, use nearby non-corresponding points, ipsilateral points, or other locations as controls to compare the immediate effects of stimulation at different sites.

Fourth, employ standardized measures of pain intensity, range of motion, and functional ability, thereby reducing reliance on purely subjective descriptions.

Fifth, conduct repeated verification, blinded observation, and multicentre studies to assess reproducibility among different physicians, patients, and medical conditions.

Sixth, record not only successful cases but also ineffective cases and localization errors in order to analyse the indications, limitations, and causes of treatment failure.

Seventh, use three-dimensional body scanning, motion capture, computer modelling, and statistical analysis to transform morphological relationships into measurable data.

A genuine scientific theory must be capable of making testable predictions and must also allow experimental findings to modify the theory itself. Only through continuous, rigorous, and transparent clinical verification can Human Body Geometry in traditional Chinese medicine gradually develop from a promising clinical discovery into a mature field of research.

VIII. Conclusion

The discovery of the 3C technique suggests that the human body may contain not only the relationships already described by anatomy, physiology, and meridian theory, but also geometric relationships that have not yet been systematically investigated. Similarity, symmetry, crossing, inversion, orientation, and precise location may together constitute an internal structural order within the human body.

From the initial reflection prompted by treating contralateral calcaneal pain using the Guguan, Muguan, and Zhongguan points to the successive verification of correspondences between the fingers and toes and between the metacarpals and metatarsals, the development of the 3C technique demonstrates that a clinical observation can inspire a geometric hypothesis. A geometric hypothesis can then be used to deduce new corresponding positions, and these deductions must subsequently be tested in clinical practice.

The fundamental concept underlying this research pathway is: Form is information; position carries meaning.

Developing research on Human Body Geometry in traditional Chinese medicine is not intended to challenge meridian theory, anatomy, physiology, or neuroscience, but to add a long-neglected dimension of investigation. Mathematical and geometric reasoning can help us discover principles within fragmented clinical observations, while clinical experimentation determines whether those principles are real and reliable. The combination of these two approaches may promote the development of acupuncture in traditional Chinese medicine toward greater standardization, scientific rigor, precision, and digitalization.

Therefore, establishing Human Body Geometry in traditional Chinese medicine is important not only for refining the theoretical foundations of the 3C technique itself. It may also open a new path toward reconsidering the structure of the human body, developing precision acupuncture, and promoting scientific innovation in traditional Chinese medicine. Without investigating the geometric relationships of the human body, our understanding of medicine and the human body may continue to lack an essential dimension. In this sense, medicine without geometry is indeed a medicine that remains incomplete.
