Four-Level Thinking: Rethinking Chinese and Western Medicine
Preface to Four-Level Thinking: Rethinking Chinese and Western Medicine
— How Four-Level Thinking Gives Chinese and Western Medicine a Shared Language for the First Time
For many years, “Chinese medicine versus Western medicine” has been an endless debate.
Some insist that Chinese medicine is true holistic medicine;
others believe that Western medicine is the only real science.
Some people worship machines and data,
while others place their trust in meridians and qi–blood.
The more heated the debate becomes,
the simpler the conclusions tend to be.
The richer the information,
the poorer the understanding.
Why?
Because we have been trying to compare two medical systems that operate on different levels of understanding,
while forcing them onto the same flat plane.
The issue is not whether Chinese medicine is “better” or Western medicine is “better”,
but that they look at the human body from different cognitive levels.
I. Why Do Debates Between Chinese and Western Medicine Never End?
Because we are trying to compare two multi-dimensional systems
with a single, linear way of thinking.
Western medicine starts from points:
tissues, organs, lab values, anatomical structures, lesions.
Chinese medicine starts from fields:
qi, shen (spirit), meridians, constitution, rhythms.
They are not looking at the same picture.
So most arguments are essentially asking:
“Which is better – the microscope or the satellite image?”
The microscope gives you clarity, but over a very small area.
The satellite image gives you the whole landscape, but with fewer details.
The real question is not which one to choose,
but what each of them is actually able to see.
To make this debate meaningful,
we need a higher-level coordinate system.
II. Four-Level Thinking: Re-understanding the Human Body Through Point, Line, Plane and Spirit
After more than forty years of clinical practice
— spanning Western medicine, Chinese medicine, structural medicine, and neurological diagnostics —
I gradually realized one thing:
The human body cannot be understood from a single level.
Out of this realization came a simple yet powerful framework:
Point → Line → Plane → Spirit
Level One: Point
We look at the local, the structural, the lesion, the lab value.
This is where modern Western medicine is strongest:
emergency care, surgery, infection control, intensive care.
Level Two: Line
We look at connections and directions between points:
neural pathways, tension lines, meridian routes, chains of symptoms and causality.
This is the core of traditional medicine, modern pain medicine, and functional medicine.
Level Three: Plane
We look at the whole system and network:
overall posture, tension fields, the global circulation of qi and blood,
the autonomic nervous system,
and the interaction between sleep, metabolism and emotion.
This is key to understanding chronic illness, functional disorders, and constitutional patterns.
Level Four: Spirit (Field)
We look at the integration of life:
emotion, will, self-healing capacity, biological rhythms, central integration,
and how the “life field” governs the entire body.
These four levels are not mysticism.
They are different tiers of cognition.
This is the framework I distilled after many years of observing and treating real human bodies.
III. How Four-Level Thinking Gives Chinese and Western Medicine a Shared Language
Once we use this four-level framework to examine the two medical systems,
things suddenly become clearer:
Western medicine is strongest at:
Level One (Point) and part of Level Two (Line).
It is precise, measurable, verifiable, operable, and controllable.
It is highly effective for clear lesions, structural damage, acute and critical conditions.
Chinese medicine is strongest at:
Level Two (Line), Level Three (Plane), and Level Four (Spirit).
It focuses on overall patterns, trends and directions,
on systems, life fields, rhythms and constitution.
It can explain why problems recur,
why they spread,
why they become widespread or systemic,
and why “one place hurts but the origin is somewhere else” —
precisely where Western medicine is relatively weak.
Each system has its strengths and its limitations.
Because they stand on different levels,
they are in fact complementary rather than mutually exclusive.
Four-level thinking is not designed to “reconcile” the two sides,
but to show that:
Many of the arguments were never on the same level to begin with.
When we stand on the ground of four-level thinking,
the differences between Chinese and Western medicine are no longer a binary opposition,
but a multi-layered panorama in which the two systems
reveal and complete each other.
IV. Why Am I Writing This Series?
Because I have seen too many people trapped between systems:
-
They undergo countless tests, yet no cause is found.
-
They take many medications, yet the problem does not resolve.
-
They follow one theoretical model of treatment,
but never consider the entire functional pathway behind it. -
They fixate on a single point,
while neglecting the whole plane of interaction. -
They are caught in debates,
yet never truly understand the foundations of either medical system.
I hope to use the simplest possible framework
to help ordinary people — and even doctors —
re-understand both Chinese medicine and modern Western medicine.
To see their validity,
and also to see their boundaries.
This is popular science,
but it is also a systematic整理 of medical thinking —
and perhaps the groundwork for a future book.
V. This Will Be a Series, and Also a Doorway
Starting from this preface,
I will write step by step from several angles:
-
Understanding the human body through four-level thinking
-
Understanding diagnosis through four-level thinking
-
Comparing treatment logic through four-level thinking
-
Looking at chronic illness, pain, and functional medicine through four-level thinking
-
Looking at emotion, sleep, and the nervous system through four-level thinking
-
Understanding constitution, rhythms, and the life field through four-level thinking
-
Why, in the end, modern and traditional medicine must converge at the “Spirit level”
This project is both popular science and theoretical construction.
It speaks to the general public,
but also to the doctors of the future.
This is the starting point of the series.
My hope is that, by walking this path,
we can move the conversation between Chinese and Western medicine:
-
from argument → to understanding
-
from mutual exclusion → to mutual complementarity
-
from fragmentation → to genuine integration
In the end, medicine is not a forced choice between two camps.
In the end, medicine is about seeing the larger picture.
Chapter One · Four-Level Thinking: The Foundational Language for Understanding the Human Body
(English Translation)
The human body is complex.
No single layer of understanding can fully explain it.
Any medical system that relies on only one perspective will inevitably encounter blind spots.
Four-Level Thinking divides all human phenomena into four cognitive layers:
Point — structure and locality
Line — connection and direction
Plane — system and global pattern
Spirit — integration and vital intention
This is a self-consistent framework with no overlap and no gaps.
It does not create a new form of medicine—it simply places each medical system back into its proper cognitive level.
I. Level One: Point — The Layer of Structural Units
Definition
A Point is the smallest observable unit of the human body—structural, local, and material.
Points include:
-
Organs, anatomical regions, nerves, muscles, tendons
-
Lesions visible on imaging (herniations, tears, degenerations)
-
Laboratory markers (glucose, CRP, hormones, etc.)
-
Any unit that can be measured, quantified, or precisely located
Nature of Point:
Static, local, divisible—the material reality of the body.
What Points can explain:
-
Trauma, tears, fractures
-
Infections, tumors
-
Organ failure
-
Abnormal blood or biochemical markers
-
Acute diseases and critical conditions
What Points cannot explain:
-
Referred pain (belongs to Line)
-
Postural problems (belongs to Plane)
-
Emotion-induced pain (belongs to Spirit)
-
Functional disorders with normal structure (Line/Plane)
A Point can explain local facts,
but cannot explain global relationships.
II. Level Two: Line — The Layer of Connection and Dynamics
Definition
A Line is the dynamic relationship between Points—its direction, pathway, and causal chain.
It asks: “From where to where? And why does one part influence another?”
Lines include:
-
Neural pathways
-
Tension-transmission pathways
-
Muscle synergy pathways
-
Force lines (e.g., ground reaction → pelvis → spine)
-
Meridian directional pathways
-
Qi movement (ascending/descending)
-
Symptom chains (numbness → weakness; bloating → back pain)
Nature of Line:
Dynamic, causal, directional — a mechanistic explanation.
What Lines can explain:
-
Why foot pain originates from the lumbar spine
-
Why shoulder pain originates from the neck
-
Why stress affects digestion
-
Why pain radiates or “pulls” to another area
-
How functional disorders flare or subside
What Lines cannot explain:
-
Multi-system interactions (Plane)
-
Autonomic nervous system integration (Spirit)
-
Constitution and biological rhythms (Plane/Spirit)
Lines explain relationships,
not the whole system.
III. Level Three: Plane — The Layer of Systems and Global Patterns
Definition
A Plane consists of many Lines woven together into a unified operating system.
It examines systemic behavior, not local behavior.
Planes include:
-
Global posture (upper/lower crossed syndrome, pelvic tilt)
-
Integrated muscle–fascia–skeletal system
-
Autonomic nervous system (sympathetic/parasympathetic patterns)
-
Overall visceral functional patterns
-
The meridian network system
-
Interactions among emotion, metabolism, and sleep
-
Constitution and life rhythms
Nature of Plane:
Systemic, holistic, network-based, field-like.
What Planes can explain:
-
Why prolonged sitting causes multi-site pain
-
Why low back pain and leg pain often coexist
-
Why “poor digestion → poor sleep → palpitations → neck tension”
-
Why posture affects visceral function
What Planes cannot explain:
-
Will, intention, vital direction (Spirit)
-
Deep psychological trauma (Spirit)
Planes explain system-level patterns,
but not life-level integration.
IV. Level Four: Spirit — The Layer of Life Integration
Definition
Spirit is the highest integrative capacity of a living organism—
governing emotion, consciousness, will, self-healing, and adaptive capacity.
This is not a religious concept.
It is the medical concept of the body’s Central Integrator.
Spirit includes:
-
Autonomic nervous integration (sympathetic/parasympathetic balance)
-
The brain’s interpretation of pain
-
Emotional and behavioral patterns
-
Will and purposefulness
-
Sleep rhythms
-
Recovery capacity
-
The sense of vitality
Nature of Spirit:
The central governing system of life—
determining how a person lives, reacts, recovers, and experiences pain.
What Spirit can explain:
-
Why stress leads to full-body pain
-
Why chronic illnesses can persist for ten years
-
Why some people are prone to anxiety and pain amplification
-
Why “poor sleep → poor mood → poor physical function”
-
Why some patients worsen despite treatment
What Spirit cannot explain:
-
Definite structural lesions (Point)
-
Confirmed anatomical damage (Point)
Spirit explains how life operates itself,
the core of the four levels.
Summary of This Chapter
Point is static.
Line is dynamic.
Plane is systemic.
Spirit is integrative.
The four levels do not conflict, do not overlap, and leave no blind spot.
Together they form the simplest and most stable language
for understanding every phenomenon of the human body.
Chapter Two · The Tensional System: The Common Foundation of Structure and Function
(English Translation)
Over the past decades, the concept of the myofascial chain has become extremely popular—especially in structural medicine, physiotherapy, and sports rehabilitation. It has been widely used to explain posture, pain, and movement patterns.
However, when placed within the framework of Four-Level Thinking, two major problems immediately appear:
-
It is too linear and cannot reflect the truly holistic, field-like nature of human tension.
-
The word “chain (line)” easily conflicts with the second level of this book—Line (connection and direction).
Therefore, in this book, I will no longer use the term “myofascial chain.”
Instead, I adopt a more scientific, systematic, and Four-Level-compatible concept:
The Tensional System
It represents the modern medical understanding of the deep coupling between structure, biomechanics, posture, and the nervous system.
It is one of the most important ways Western medicine contributes to understanding the human body as an integrated whole.
2.1 Concept of the Tensional System
The tensional system refers to:
A continuous, body-wide network formed by fascia, muscles, tendons, ligaments, neural tension, visceral suspensory structures, and pressure systems of the body cavities.
This network can pull or anchor, transmit force or regulate nerve function,
influence structure or modulate function.
It is the body’s:
-
Structural framework
-
Mechanical distribution system
-
Postural maintenance system
-
Movement coordination system
-
Foundation of pain and compensation
-
Channel through which emotions affect the body
Simply put:
The tensional system is one of the most important—and most overlooked—systems of the human body.
2.2 Components of the Tensional System
The tensional system spans the entire body and is composed of multiple layers:
1) Fascia
Envelops, connects, and separates all structures.
It is the main carrier of tension and has continuity, plasticity, and extensibility.
2) Muscles and Myofascia
Muscle contraction and relaxation alter local tension and transmit force through fascia—
the main source of dynamic tension.
3) Tendons and Ligaments
Anchor tension and muscle force to bones or structural nodes—
the “hooks” that direct tensional pathways.
4) Neural Tension
Nerves possess tension properties as well.
Stretch, compression, or irritation can alter pain patterns and motor control.
Examples:
Sciatic nerve tension → unstable gait
Cervical nerve tension → hand numbness
5) Bone Anchor Points
Bony prominences (tuberosities, spines, ridges) act as key attachment and redirection points for tension.
6) Visceral Suspensory System
Ligaments and mesenteries that suspend organs:
Tension in these structures greatly affects the musculoskeletal system.
Examples:
Tight stomach → back pain
Tight diaphragm → neck/shoulder strain
Pelvic organ tension → lumbosacral discomfort
7) Pressure Systems of the Body Cavities
Thoracic, abdominal, and pelvic pressures shape the overall tensional pattern.
The true “core system” consists of:
-
Diaphragm
-
Pelvic floor
-
Transversus abdominis
-
Multifidus
Together, these form a continuous, integrated tension-regulating mechanism.
These elements collectively form a continuous, unified tensional network
that supports human posture, movement, and adaptability.
2.3 Primary Tensional Directions: From “Chains” to a Tensional Field
Although the tensional system is one integrated network, tension in space is not evenly distributed.
Through millions of years of evolution, the human body developed several Primary Tensional Directions that determine:
-
Posture
-
Movement chains
-
Pain distribution
-
Compensation patterns
Traditional structural medicine refers to these as “deep front line,” “superficial front line,” “superficial back line,” and “lateral line.”
To avoid confusion with Level Two (“Line”), I redefine them as:
Primary Tensional Directions
-
Deep Tensional Axis
-
Anterior Tensional Surface
-
Posterior Tensional Surface
-
Lateral Tensional Surface
These four directions form the main framework of the tensional system.
2.3.1 Deep Tensional Axis — The Core Stability Mast
Corresponds to the traditional Deep Front Line,
but this book emphasizes the axis, not a line.
Includes:
-
Diaphragm
-
Psoas and iliacus
-
Transversus abdominis, multifidus
-
Pelvic floor
-
Deep spinal muscles
-
Mesenteric and visceral suspensory structures
Functions:
-
Maintain internal stability
-
Regulate breathing efficiency
-
Establish the “central axis” of posture
-
Influence visceral function
-
Determine whether the body can truly “stand tall” or “flex naturally”
Clinical significance:
-
Excessive deep tension → sympathetic dominance → insomnia, anxiety, stiff neck and shoulders
-
Insufficient deep tension → low back pain, weak legs, pelvic instability, collapsed core
This is one of the most common—and most overlooked—roots of dysfunction.
2.3.2 Anterior Tensional Surface — The Dynamic Surface
Corresponds to the Superficial Front Line.
Includes:
-
Pectoralis major/minor
-
Rectus abdominis
-
Hip flexor group
-
Tibialis anterior
-
Foot dorsiflexors
Functions:
-
Flexion and forward movement
-
Step length and forward propulsion
-
Pelvic tilt
-
Coordination among chest, abdomen, hips, and foot
Clinical significance:
-
Excessive tension → kyphosis, chest tightness, forward head posture, hip-flexor low back pain
-
Weak tension → unstable standing, weak running power, abdominal sagging
A major problem in modern sedentary lifestyles.
2.3.3 Posterior Tensional Surface — The Stability Surface
Corresponds to the Superficial Back Line.
Includes:
-
Plantar fascia
-
Gastrocnemius–soleus complex
-
Hamstrings
-
Gluteus maximus
-
Erector spinae
-
Neck extensors
-
Scalp fascia
Functions:
-
Upright posture
-
Spinal curvature integrity
-
Tensile recoil during gait
-
Posterior body stability
Clinical significance:
-
Excessive tension → posterior chain tightness, low back pain, headaches, cervical compression
-
Weak tension → kyphosis, weak low back, fatigue from walking
This is one of the strongest generators of pulling-type pain.
2.3.4 Lateral Tensional Surface — The Balance Surface
Corresponds to the Lateral Line.
Includes:
-
Gluteus medius/minimus
-
Tensor fascia lata
-
Iliotibial band
-
Quadratus lumborum
-
Lateral abdominal muscles
-
Lateral cervical muscles
-
Lateral foot muscles
Functions:
-
Lateral stability
-
Rotation control
-
Gait stabilization
-
Pelvic leveling
-
Shoulder height symmetry
Clinical significance:
-
Excess → pelvic shift, scoliosis, ITB pain, lateral hip pain
-
Weak → poor stair climbing, gait drifting, unstable posture
Nearly all patients with “misalignment” have lateral tensional imbalance.
2.3.5 Integration of the Four Directions: The Tensional Field
These directions are not separate—they combine into a Tensional Field, determining:
-
Posture
-
Gait pattern
-
Spinal curvature
-
Pelvic rotation
-
Shoulder–neck configuration
-
Compensation
-
Pain distribution
-
Emotional tension patterns
-
Autonomic nervous balance
This is the structural bridge from Point → Line → Plane → Spirit in Four-Level Thinking.
2.4 Functions of the Tensional System
The tensional system governs almost all major structural and functional behaviors of the body:
1) Posture
Posture is not created by bones.
Bones are simply “pulled” into position by tension.
Kyphosis
Forward head posture
Shoulder asymmetry
Pelvic tilt
O/X legs
All are tensional patterns, not bone problems.
2) Stability
The body’s stability does not come from joint surfaces “locking,”
but from balanced tension.
When tension distribution fails, all structures drift out of place.
This explains why many “misalignments”
reset themselves when tension changes.
3) Movement Coordination
The tensional system determines:
-
The sequence of muscle activation
-
Synergy among regions
-
How movement chains operate
-
How force transmits through the body
Walking, running, lifting, and sports performance
are all patterns of tensional coordination.
4) Pain and Compensation
Pain is rarely caused by “local damage.”
Most pain originates from uneven tension.
Examples:
-
Tight calf → low back pain
-
Tight scalenes → hand numbness
-
Tight hip flexors → knee pain
-
Tight diaphragm → upper back pain
-
Tight pelvic floor → lumbosacral pain
Compensation is the tensional system’s automatic survival strategy.
When one region cannot hold tension, another region takes over—
causing new pain.
5) Neural Function
The tensional system is tightly coupled with the nervous system:
Excess tension → sympathetic overdrive → poor sleep, fast heartbeat, anxiety
Proper relaxation → parasympathetic activation → better digestion, reduced pain, better recovery
This is the foundational mechanism behind
“why emotions affect the body.”
2.5 The Tensional System Within the Four-Level Framework
Placed back into the Four-Level Thinking model, the tensional system aligns perfectly:
Level One: Point
Local expressions of tension:
-
Fascia nodes
-
Muscle attachment points
-
Bone protrusions
-
Tender points
-
Tight spots
Level Two: Line
Directional expressions of tension:
-
Tensional pathways
-
Pulling directions
-
Force lines from one point to another
We intentionally avoid the word chain to prevent confusion with Level Two “Line.”
Level Three: Plane
System-level patterns:
-
Global posture
-
Compensation patterns
-
Balance and imbalance
-
Upper/lower crossed syndromes
-
Pelvic tilt
-
The entire tensional field
Level Four: Spirit / Field
Tension influenced by higher integrative processes:
-
Emotion → neck/shoulder tension
-
Stress → diaphragm contraction
-
Fear → full-body tightening
-
Sleep → parasympathetic balance → tension decreases or increases
-
Breathing patterns → determine tensional rhythm
The tensional system is the structural bridge connecting
Point → Line → Plane → Spirit.
Chapter Three · The Meridian System: Ancient System Science of the Human Body
(English Translation)
Within the framework of modern medicine, many people think that “meridians” are simply:
-
The twelve primary channels
-
The eight extraordinary vessels
-
A few hundred acupuncture points
-
Some invisible dotted lines drawn on the body
This understanding is far too superficial.
The true Meridian System is an ancient systems model of human life.
It is not a single structure, but an attempt to place:
Structure, function, qi–blood, nerves, emotion, somatic reactions,
internal–external connections, pain patterns, constitution and rhythms
all together on a single functional map of the human body.
In modern terms, it is similar to how we speak about:
-
The nervous system — not a single nerve
-
The immune system — not a single organ
-
The tensional system — not just one fascial chain
In exactly the same way:
The Meridian System is not “a few lines,”
but a multi-layered systems model.
3.1 The Meridian System ≠ Meridian Channels
(The most important idea of this chapter)
Modern readers often confuse “meridian system” with “meridian channels.”
In fact:
Meridian System = Meridians + Jingjin + Divergent Channels + Collaterals + Cutaneous Zones
as an integrated whole.
The meridian system is not a structure,
not an organ,
not a few linear lines.
It is:
An ancient systems model expressed in the language of “lines.”
If we translate it into modern medical terms, we can compare it this way:
| System | Single structure? | Multiple subsystems? | Functional whole? |
|---|---|---|---|
| Nervous system | No | Yes | Yes |
| Immune system | No | Yes | Yes |
| Tensional system | No | Yes | Yes |
| Meridian system | No | Yes | Yes |
The scientific value of the meridian system does not depend on
whether it can be dissected as one line,
but on whether it can explain the integrated logic of the human body.
And in practice—it does so remarkably well.
3.2 The Five Subsystems of the Meridian System
The ancient physicians abstracted and compressed the body’s structure and function into five main components.
Each plays a specific role, and together they present the full Meridian System.
① Meridians (Jingmai) — Functional Trunk Lines
Including:
-
The twelve primary meridians
-
The eight extraordinary vessels
Characteristics:
-
Directionality
-
Interior–exterior (biao–li) relationships
-
Ascending/descending, entering/exiting
-
Clearly described pathways and patterns of spread
Functions:
-
Describe the directional flow of qi and blood
-
Describe the evolution and spread of disease
-
Describe functional connections between organs and regions
-
Describe the migration and transformation of symptoms
In modern language, meridians are roughly equivalent to:
A mixed “functional pathway” combining neural, vascular, tensional, and metabolic elements.
② Jingjin — The Ancient Language of the Tensional System
Jingjin (muscle–tendon regions) correspond to:
-
Muscle synergy directions
-
Fascial tension
-
Postural control
-
Pathways of referred pain
-
Movement chains
Its core meaning is:
Using Chinese medical language to describe structure and the tensional system.
Common clinical examples:
-
Tight calf → low back pain
-
Tight scalenes → hand numbness
-
Pelvic instability → leg pain
All of these can be interpreted within the framework of Jingjin.
③ Divergent Channels (Jingbie) — Deep System Pathways
Divergent channels connect:
-
Deep visceral organs
-
Deep neural structures
-
The shortest paths between internal organs and the body surface
They explain:
-
How internal disorders manifest externally
-
How emotions transform into somatic symptoms
-
Why stomach disorders can cause back pain
-
Why anxiety can cause chest tightness
In modern terms, they represent an ancient description of:
Deep neuro–visceral integration pathways.
④ Collaterals (Luo Mai) — Networks and Crosspoints
Modern equivalents include:
-
Nerve branches
-
Fascial crosslinks
-
Cutaneous reflex zones
-
Pain-sensitive regions
Collaterals transform “lines” into networks.
They are the key bridge by which the meridian system moves from:
Level Two (Line) → to Level Three (Plane)
⑤ Cutaneous Zones (Pibu) — Autonomic Response Zones on the Surface
Modern equivalents:
-
Autonomic regulation of the skin
-
Changes in skin temperature
-
Altered pain sensitivity
-
Cutaneous signs of sympathetic activation
Many “pibu reactions” are in fact the external manifestations of:
Autonomic nervous system dysregulation.
3.3 The Meridian System as a Cross-Disciplinary, Multi-Level Life Model
When we combine all five subsystems,
the meridian system appears as:
Structure (Jin) + Function (Mai) + Deep Systems (Bie) + Networks (Luo) + Body Surface (Pi)
together forming a life-operation model.
It can simultaneously explain:
-
Structural pain
-
Functional disorders
-
Emotion-related pain
-
Organ–surface interactions
-
Trends and trajectories of disease evolution
-
Constitutional patterns and life rhythms
This is arguably the highest-level language
ancient physicians used to describe the overall operation of the human body.
3.4 The Meridian System Within Four-Level Thinking
Meridians are not a single line.
They span all four levels of the framework:
Level One: Point
Manifestations:
-
Acupuncture points
-
Tender points
-
Jingjin attachment points
-
Cutaneous hypersensitive zones
→ At the Point level, the meridian system appears as local functional points.
Level Two: Line
Manifestations:
-
Meridian pathways
-
Jingjin routes
-
Directions of disease propagation
-
Ascending/descending of qi
→ At the Line level, the meridian system appears as connections and directions.
Level Three: Plane
Manifestations:
-
Overall circulation of qi and blood
-
Yin–yang balance
-
Constitutional patterns
-
Coupling among emotion, sleep, viscera, and body surface
-
Global meridian states (cold, heat, deficiency, excess)
→ At the Plane level, the meridian system appears as systemic integration.
Level Four: Spirit / Field
Manifestations:
-
Emotional states
-
Consciousness
-
Rhythms
-
Life drive and motivation
-
Mind–body integration capacity
→ At the Spirit level, the meridian system expresses the highest integration layer of the life system.
3.5 In One Sentence: The Final Definition of the Meridian System
The meridian system is not “a few lines,”
but a multi-system holistic network described in the ancient language of “lines.”
-
Meridians (Jingmai) are functional trunk lines
-
Jingjin are the structural layer
-
Divergent channels are deep system pathways
-
Collaterals are the network connections
-
Cutaneous zones are the surface responses
Together, they form one of the earliest system-science models of the human body.

Chapter 4 · How Chinese Medicine and Western Medicine Understand the Human Body under the Four-Tier Thinking Framework
(Faithful English Translation)
To understand the differences between Chinese medicine and Western medicine, we must begin with one fundamental question:
“How does each system view the human body?”
The foundation of medicine is not treatment, but first answering a deeper question:
“What is the human body?”
Different “body models” lead to different diagnostic logics, treatment methods, explanations of disease, and medical systems.
The Four-Tier Thinking framework offers a shared coordinate system so that both medical traditions can be compared on the same map—without confusion or category mistakes.
Below, I will analyze how Chinese and Western medicine understand the body from the four levels: Point, Line, Plane, and Spirit.
1. First Tier: Point — the Foundation of Western Medicine, the Blind Spot of Chinese Medicine
A “point” is a structure, a local unit, something visible, measurable, and tangible.
Western medicine builds its body model from the level of “points”:
-
The body is composed of organs
-
Organs are composed of tissues
-
Tissues are composed of cells
-
Cells are composed of molecules
-
Every structure has a precise location and function
-
Every disease corresponds to a “lesion”
In Western medicine:
The human body is a precise machine made of countless structural points.
This makes Western medicine extremely strong at the “Point” level:
✔ Trauma
✔ Infection
✔ Tears, ruptures
✔ Surgical removal
✔ Structural defects
✔ Lab indicators
✔ Organ failure
✔ Emergency and critical care
As long as the lesion can be “seen,” Western medicine can treat it precisely.
But “points” have inherent limitations. They cannot explain:
✘ Referred pain
✘ Severe pain with completely normal imaging
✘ Emotional stress causing stomach discomfort
✘ Poor sleep causing neck and shoulder tightness
✘ Why a cluster of symptoms appears together
✘ Functional disorders with no structural abnormalities
These are not phenomena that the language of “points” can describe.
Chinese medicine is relatively weak at this tier.
It has the concepts of five zang-organs and six fu-organs, qi, blood, and body fluids,
but lacks detailed anatomical structure.
2. Second Tier: Line — Both Systems Are Strong, But Use Different Languages
A “line” represents relationships between points: direction, transmission, and causal pathways.
In Western medicine:
✔ Neural pathways
✔ Vascular supply lines
✔ Biochemical reaction chains
✔ Force lines (ground → foot → knee → hip → spine)
✔ Temporal progression of disease
Western medicine’s “lines” are precise, but often confined to local systems.
Chinese medicine has a different language for “lines”:
✔ Meridian pathways
✔ Jingjin (myofascial) tension lines
✔ Qi movement—ascending, descending, entering, exiting
✔ Liver qi stagnation → bloating → chest tightness
✔ Spleen deficiency → dampness → joint pain
Chinese medicine observes how lines interact,
not only which “point” is abnormal.
Western medicine excels at anatomical pathways;
Chinese medicine excels at functional pathways.
Different languages, but the same purpose:
to explain why A affects B.
3. Third Tier: Plane — The Domain Where Chinese Medicine Excels and Western Medicine Is Weak
A “plane” is a system, a whole, a network, a field.
The Plane tier deals with:
-
Overall posture (upper/lower crossed syndromes)
-
The meridian network
-
Tensional fields (tightness, looseness, imbalance)
-
Autonomic nervous system
-
Emotion–sleep–metabolism interactions
-
Systemic inflammation
-
Visceral–somatic correlations
-
Whole-body qi-blood patterns
-
Cold–heat, deficiency–excess
-
Constitutional patterns
Chinese medicine has used the language of “planes” from the very beginning:
✔ The whole body is affected
✔ Exterior–interior, cold–heat
✔ Yin and yang shifts
✔ Top–bottom connections
✔ Five-organ interactions
✔ Symptoms appear “in clusters”
✔ Symptoms improve or worsen together
This is naturally a holistic/systemic vocabulary.
Western medicine at this tier remains weak:
✘ Hard to explain “long sitting → pain everywhere”
✘ Hard to explain stomach discomfort → insomnia → palpitations
✘ Hard to explain why low back pain + leg pain occur together
✘ Hard to explain stress → irritable bowel
✘ Hard to explain interactions between posture and visceral function
Western systemic frameworks in immunity, neurology, and metabolism are developing,
but still not mature.
4. Fourth Tier: Spirit — The Core of Chinese Medicine, and a Domain Western Medicine Has Not Yet Named
“Spirit” (Shen) represents the highest level of life integration:
-
How emotions influence the body
-
How bodily sensations influence emotions
-
Why some people repeatedly fall ill at certain life stages
-
Why self-healing ability rises or collapses
-
Why the same disease heals in 3 days for one person and 3 years for another
-
Why trauma (emotional or physical) can freeze the body
-
Why sleep, intention, and rhythm alter metabolism
-
Why the whole person deteriorates or recovers as one
Chinese medicine has a profound understanding of this:
✔ The Heart governs Shen
✔ The Liver governs Qi movement
✔ The Kidneys store willpower
✔ The Spleen governs thought
✔ When Shen is disturbed, disorder appears
✔ When Qi is chaotic, illness arises
These are all languages of life integration.
Western medicine has no complete framework here. It fragments the explanation:
-
Some in “sympathetic/parasympathetic balance”
-
Some in “psycho-neuro-immunology”
-
Some in “brain network activity”
-
Some in “stress physiology”
But there is no unified concept.
This is exactly the purpose of the Four-Tier model:
Spirit is not mysticism; it is the body’s highest integrative function.
5. Four-Tier Thinking Allows the Two Medical Systems to Stand Side-by-Side
One-sentence summary of their positions within the four tiers:
Western medicine is strong in Point → Line (structure → cause);
Chinese medicine is strong in Line → Plane → Spirit (relation → system → life-field).
Thus:
-
Western medicine is precise.
-
Chinese medicine is holistic.
-
Western medicine sees “damaged components.”
-
Chinese medicine sees “patterns of operation.”
-
Western medicine excels in acute, trauma, and critical care.
-
Chinese medicine explains chronicity, pattern, recurrence, and systemic illness.
They are not in competition—
they simply observe from different entry points.
Four-Tier Thinking finally puts them on the same map.
Core sentence of this chapter:
Western medicine enters the body from “Points”; Chinese medicine enters from “Planes.”
The Four-Tier Thinking model is the shared language between them.
Chapter 5 · The Rise of “Peripheral Disciplines” in Modern Western Medicine
When all medical systems across the world are placed inside the framework of the Four-Level Thinking Model, one striking pattern becomes clear:
Western medicine begins at Level 1 (Point),
Traditional Chinese Medicine begins at Levels 3–4 (Plane–Spirit),
and modern diseases are forcing both to converge toward the same direction.
This chapter does not discuss culture, ideology, or historical bias.
It analyses a simple structural fact:
Diseases evolve → Medicine must evolve.
1. The Origin of Western Medicine: The Brilliance and Limits of a Level-1 System
Western medicine was born from anatomical revolutions, microscopy, pathology, and experimental science.
It is a classic Level-1 medicine — centered on Point, structure, and lesion.
Level-1 medicine excels in areas where “the problem has a location”:
-
Inflammation → anti-inflammatory drugs
-
Infection → antibiotics
-
Laceration → suturing
-
Fracture → reduction and fixation
-
Organ necrosis → resection
-
Tumor → surgery / radio-chemotherapy
-
Abnormal lab values → pharmaceutical correction
Without Level-1 medicine, human life expectancy and survival from acute disease would not be what they are today.
However—
Level-1 medicine is bound by its level.
It can only deal with what is:
-
visible
-
measurable
-
structural
-
localized
But modern diseases are increasingly:
-
systemic
-
functional
-
referred
-
emotional
-
rhythmic
-
compensatory
-
neuro-tensional
-
field-based
These cannot be described in a “point-based” language.
Thus we see a paradox of modern healthcare:
More tests are normal → More patients feel unwell.
2. When Level-1 Medicine Cannot Explain Modern Illness, Western Medicine Produces “Peripheral Disciplines”
This evolution did not come from cultural integration or philosophical reflection.
It came from clinical reality.
Western doctors see it every day:
-
Normal imaging but disabling pain
-
Stress → immediate gastrointestinal reaction
-
Chronic pain migrating across regions
-
Low sleep → system-wide dysfunction
-
Pelvic tilt → whole-body compensation
-
Emotional trauma → long-term physical “freezing”
These phenomena cannot be understood through points alone.
So naturally, Western medicine generates three major branches that extend upward:
3. Peripheral Disciplines: Western Medicine Ascending to Levels 2–4
(1) Disciplines moving toward Level 2 (Line)
These fields explore relationships between points, i.e., pathways:
-
Sports medicine
-
Chiropractic / spinal manipulation
-
Neuromuscular medicine
-
Neurodynamics
-
Kinetic chains and movement science
These correspond, remarkably, to TCM concepts like:
Jingjin (musculo-tensional pathways) + Meridians (functional pathways).
Key recognitions include:
-
Low back influences the leg
-
Neck influences the hand
-
Ankle affects the knee
-
Pelvis affects spinal alignment
-
Force transmission is global, not local
This is the essence of Level-2 cognition.
(2) Disciplines moving toward Level 3 (Plane)
These fields focus on systems, balance, compensation, and bodywide patterns:
-
Physical therapy
-
Posture medicine
-
Rehabilitation medicine
-
Fascial therapy
-
Biomechanics
-
Core stability systems
Their vocabulary becomes strikingly similar to traditional Chinese concepts:
-
Global compensation
-
Upper–lower linkage
-
Left–right balance
-
Tight here → loose there
-
Posture determines function
-
Tensile field governs pain
This is Western medicine entering the Plane Level (Level-3).
(3) Disciplines moving toward Level 4 (Spirit / Field)
A major shift has emerged:
Western medicine now recognizes that emotion, sleep, stress, trauma, and rhythm are primary drivers of chronic illness.
This has led to the development of:
-
Psychosomatic medicine
-
Autonomic nervous system medicine
-
Vagal nerve modulation
-
Pain neuroscience education (PNE)
-
Trauma-informed therapies
-
Sleep medicine
-
Stress-related medicine
These concepts resonate deeply with TCM insights:
-
Disordered emotions → illness
-
Rhythm disruption → illness
-
Shen disturbance → systemic dysfunction
-
Qi chaos → organ dysfunction
Western medicine is, often unconsciously, stepping into TCM’s Level-4 territory.
**4. Why Is Western Medicine Moving Toward TCM Levels?
Not Imitation — Necessity**
There is one fundamental reason:
Modern diseases are not Level-1 diseases.
And when diseases cross levels,
medicine must follow.
Chronic pain is not a point.
Autonomic dysfunction is not a point.
Emotional-gastric syndromes are not a point.
Compensation chains are not points.
Trauma-induced bodily “freeze” is not a point.
Thus Western medicine is forced into an upward evolution:
Point → Line → Plane → Spirit
(From Level 1 → Multi-Level Medicine)
While TCM has always operated in Levels 3–4.
Therefore, both systems naturally converge.
**5. The Medicine of the Future:
Not Chinese Medicine, Not Western Medicine — but Full-Level Medicine**
Truly advanced medicine must operate across all four levels:
**Level 1: Point — structure, anatomy, lesion, acute care, surgery
Level 2: Line — pathways, force transmission, referral mechanisms
Level 3: Plane — systems, posture, compensation, rhythms, tensional fields
Level 4: Spirit — emotions, sleep, self-regulation, coherence, life integration**
Without Level-1 → no diagnosis, no surgery, no emergency care
Without Level-2 → no explanation of chains, referral, or dynamics
Without Level-3 → no understanding of systemic imbalance
Without Level-4 → no understanding of self-healing and human resilience
Any single-level medicine is incomplete.
When medicine finally spans all four levels:
-
TCM will no longer be misunderstood as mysticism
-
Western medicine will no longer be trapped in local structures
-
All systems can explain each other
-
Most debates will end automatically
Because by then, medicine will have become:
**A complete human medicine —
one that spans all four levels of human reality.**
**Chapter Six · The Modernization of Chinese Medicine:
From a “Third-Tier Medicine” Toward a Breakthrough in the First Tier**
If the previous chapter (Chapter Five) explained how Western medicine is being forced by modern diseases to climb upward (from Point → Line → Plane → Spirit),
then this chapter explains the opposite movement:
How Chinese medicine, under modern clinical demands, is being pushed downward from the 2nd–3rd–4th tiers toward the 1st tier.
This is not a cultural issue, nor a competition between systems.
It is simply the natural evolution of medicine itself.
**1. The Foundation of Chinese Medicine:
Innately a Second-, Third-, and Fourth-Tier Medicine**
Traditional Chinese Medicine (TCM) fundamentally works by:
observing the external → inferring the internal
observing overall patterns → inferring functional states
observing symptom combinations → inferring system status
Which means TCM is strongest in:
Tier 2 – Line (relationships & pathways)
-
Meridian pathways
-
Qi dynamics (“ascending, descending, entering, exiting”)
-
Jingjin (muscle–tension routes)
-
Functional cause–effect chains
Tier 3 – Plane (systems & networks)
-
Qi–blood–yin–yang dynamics
-
Organ–system interactions
-
Body constitution
-
Emotion–sleep–viscera relationships
-
The meridian system as a whole-body network
Tier 4 – Spirit (integration & regulation)
-
Emotion regulation
-
Life rhythm & vitality
-
Self-healing
-
Mind–body integration
This is why TCM excels at:
✔ Functional disorders
✔ Chronic fatigue
✔ Psychosomatic symptoms
✔ Recurrent, systemic, or unexplained syndromes
✔ Meridian-network pain patterns
✔ Autonomic dysfunction
✔ Compensatory pain patterns
In other words:
TCM was born as a “high-tier medicine.”
2. But TCM Is Significantly Weak in Tier One (Structure)
Classical TCM lacked:
✘ Anatomy
✘ Imaging
✘ Microbiology
✘ Immunology
✘ Surgical methods
✘ Structural diagnostics
✘ Tools for acute organ failure
✘ Tools for structural pathology
Therefore, in conditions like:
-
Fractures
-
Suppurative infections
-
Organ failure
-
Tumor compression
-
Acute abdomen
-
Acute nerve compression
-
Myocardial infarction, stroke
-
Rapidly deteriorating organ function
TCM had almost no structural leverage.
Not because TCM is “inferior,” but because:
TCM was created in a pre-anatomical era.
It never had Tier-1 thinking built into its language.
3. Modern Clinical Reality Is Forcing TCM to Break Into Tier One
As modern healthcare matured:
-
Imaging became universal
-
Emergency medicine developed
-
Pathology and microbiology matured
TCM practitioners must now face the question:
“What is the actual structural problem?”
Without Tier-1 judgment, you cannot safely decide whether something is or is not within your scope.
Thus two major trends have emerged:
4. Trend One: TCM Must Develop Tier-1 Diagnostic Literacy
A modern TCM practitioner who cannot distinguish:
Is this a tumor or not?
Is this a fracture or not?
Is this a nerve entrapment or just muscle tension?
Is this a bacterial infection or “heat”?
Is this organ failure or “qi deficiency”?
will inevitably make diagnostic errors.
Therefore modern TCM must learn to interpret:
-
X-ray
-
CT / MRI
-
Laboratory data
-
Signs of organ failure
-
Infection markers
-
Red flags
-
Differential diagnoses
-
Structural causes of pain or dysfunction
This is not “Westernization.”
It is the minimum requirement for safety.
To practice safely, TCM must know:
-
When not to treat
-
When to stop treatment
-
When to refer immediately
-
What is within TCM’s scope—and what is not
**5. Trend Two: The Rise of Tier-1 Treatment Tools Within TCM
The Emergence of Needling-Blades (刃针 / Micro-invasive Acupuncture)**
Techniques such as:
-刃针 (needle-knife)
-微针刀
-针刀
-浮针
have given TCM, for the first time, direct access to structural pathology.
These tools address:
✔ Nerve entrapment
✔ Fibrosis
✔ Adhesions
✔ Tendon stenosis
✔ Fascial thickening
✔ Deep nodules
✔ Tunnel syndromes
✔ Primary tension generators
All of these are Tier-1 structural problems.
In other words:
Needle-knife therapy allows TCM to enter the structural tier for the first time.
A true revolutionary leap.
6. TCM Moving into Tier One ≠ TCM Becoming Western Medicine
Many people misunderstand:
“刃针 = Westernization”
But the real logic is:
(1) TCM must master Tier-1 diagnostics to ensure safety
If you cannot recognize structural danger → you cannot practice safely.
(2) TCM must acquire Tier-1 tools to improve effectiveness
Many chronic pains are not functional—they are structural.
Herbal medicine or qi-regulation alone cannot fix fibrosis or nerve entrapment.
(3) The better TCM understands Western medicine, the more it understands TCM’s true strengths
Not:
“Learn Western medicine → lose TCM.”
But:
“Learn Western medicine → know precisely when TCM works best.”
**7. The Final Direction: Both Systems Will Become
a Single “All-Tier Medicine”**
TCM strengthens Tier One → becomes safer and more complete.
Western medicine strengthens Tier Three and Four → becomes more holistic.
Eventually all medicine will become:
Tier 1 – Structure
Tier 2 – Pathway
Tier 3 – System
Tier 4 – Life-field
ALL integrated.
At that point, there will be no more:
❌ TCM
❌ Western medicine
❌ Alternative medicine
❌ Endless arguments
Only:
One unified, four-tier, complete human medicine.
A medicine that finally sees the whole human being.
**Chapter Seven · In the Four-Tier Framework:
Western Medicine Keeps You Alive,
Chinese Medicine Helps You Live Well**
When we place all diseases into the Four-Tier Thinking framework, one fundamental truth becomes clear:
Tier 1–2 diseases determine whether you survive.
Tier 3–4 diseases determine how well you live.
Western medicine and Chinese medicine each play their roles in different strata of human health.
This chapter is not about praise or criticism.
It is about understanding why different levels of disease require different levels of medicine.
**1. Western Medicine’s Core Mission:
Treat Tier 1 & 2 Diseases — “Keep You Alive”**
Tier 1 (Point) and Tier 2 (Line) diseases share clear characteristics:
-
A specific cause
-
A clear lesion
-
Rapid progression
-
High danger
-
Require immediate intervention
Such as:
-
Acute infections
-
High fever
-
Trauma
-
Organ failure
-
Stroke, myocardial infarction
-
Malignant tumors
-
Sepsis
-
Acute nerve compression
-
Fractures and internal injuries
For these conditions, Western medicine is irreplaceable:
✔ Antibiotics save lives
✔ Surgery restores structure
✔ ICU and dialysis support failing organs
✔ Cancer therapies prolong survival
✔ Emergency medicine stabilizes the critical moment
Without Tier-1 medicine, humans would not live as long as we do today.
But Tier-1 medicine has inherent limitations:
It can only treat what is visible, measurable, and structurally defined.
Yet modern people suffer from conditions that are:
-
Systemic
-
Functional
-
Emotional
-
Stress-related
-
Neurological
-
Postural
-
Tensional
-
Related to lifestyle and rhythm
These are not Point-level problems.
This is why today:
More people feel unwell,
while more tests come back “normal.”
And in Tier 1—
Traditional Chinese Medicine simply has no structural tools.
Not because it is wrong, but because:
TCM was created in an era without anatomy or microscopes.
Tier-1 disorders were outside its conceptual world.
Thus, when life is at risk:
Western medicine is the only correct choice.
**2. Chinese Medicine’s Strength:
Treat Tier 3 & 4 Diseases — “Help You Live Well”**
Tier 3 (Plane) and Tier 4 (Spirit/Field) disorders have opposite characteristics:
-
Not immediately life-threatening
-
Often normal on imaging
-
Mechanistically complex
-
Strongly influenced by system-wide interactions
-
Persistent, recurrent
-
Profoundly impact quality of life
Such as:
-
Chronic fatigue
-
Chronic pain and widespread pain
-
Sleep disorders
-
Autonomic dysfunction
-
Stress-related visceral symptoms
-
Digestive–sleep–emotional loops
-
Recurrent migraine
-
Tension-driven symptoms
-
Postural or tensional syndromes
These conditions won’t kill you,
but they will take away the joy of life.
And here, TCM excels:
✔ Regulating qi and blood
✔ Balancing organ networks
✔ Harmonizing autonomic patterns
✔ Modulating tension fields
✔ Rebuilding physiological rhythm
✔ Improving sleep, digestion, emotions
✔ Enhancing self-healing capacity
Put simply:
Tier-3 and Tier-4 diseases are “life diseases,”
and TCM is a life-medicine.
TCM treats:
-
How you feel
-
How you function
-
How you sleep
-
How you digest
-
How you respond
-
How you enjoy life
TCM is the medicine of living well.
**3. Why TCM Works in Tier 3–4:
Because These Diseases Depend on “Inner Strength”**
Tier-3 and Tier-4 disorders are not caused by external pathogens alone.
They arise from:
-
Autonomic dysregulation
-
Tension imbalances
-
Emotional–somatic coupling
-
Rhythmic disruption
-
Reduced self-repair
-
Qi–blood stagnation
-
Systemic compensation
These are not “foreign invaders.”
They are internal misalignments.
TCM is designed precisely to restore:
-
Internal regulation
-
Rhythmic harmony
-
Emotional–somatic integration
-
Self-healing capability
-
Network balance
This is why:
✔ TCM cannot replace emergency medicine
✔ But it can restore quality of life in a way Western medicine cannot
Western medicine gives you life.
TCM gives you the life you want.
**4. A Key Reality:
Western Medicine Uses External Forces;
TCM Activates Internal Forces**
Western medicine = external intervention
-
Drugs
-
Surgery
-
Medical devices
-
Chemotherapy, radiotherapy
-
Dialysis, ICU
When external tools run out—
when no more drugs work, when no further surgery is possible—
Western medicine reaches its limit.
But this is not failure;
it simply reflects that:
Tier-1 tools cannot solve Tier-3/4 problems.
TCM = internal activation
-
Restores self-healing
-
Regulates autonomic balance
-
Unlocks tension fields
-
Rebuilds circadian rhythms
-
Restores organ–system harmony
-
Strengthens vitality
When internal regulation improves:
-
Pain decreases
-
Sleep improves
-
Anxiety softens
-
Digestion harmonizes
-
Energy returns
-
Life feels lighter and more meaningful
Quality of life depends far more on
internal capacity than external medication.
**5. The Most Rational Division of Labor:
Western Medicine for Survival,
Chinese Medicine for Quality of Life**
A one-sentence summary:
For survival → Western medicine
For living well → Chinese medicine
Acute, dangerous diseases → Western medicine
Chronic, functional, systemic, emotional conditions → TCM
This is the most scientific and balanced way to understand both medicines.
The ultimate direction of medical evolution is:
Tier-1 (Structure)
Tier-2 (Pathways)
Tier-3 (Systems)
Tier-4 (Life-Field)
A complete medicine must operate on all four tiers.
And one day—
when both traditions fully mature—
There will no longer be “Chinese medicine” and “Western medicine.”
Only a fully integrated, four-tier Complete Human Medicine.
