1️⃣ In Traditional Taiji Theory
In the classical Eight Gates (Peng, Lu, Ji, An, Cai, Lie, Zhou, Kao):
Classically, Peng is:
An expansive structural energy that supports and fills in all directions.
It is not defined by height or angle.
2️⃣ In Modern Teaching & Coaching
However, in modern instruction — especially in push-hands and competition routines — teachers sometimes use descriptive terms such as:
Low Peng
Level Peng
Diagonal Peng
Upward Peng
Downward Peng
These are not separate jins (energies).
They are directional applications of Peng structure.
So they are pedagogical terms, not classical categories.
3️⃣ How to Say It Properly in English
Instead of saying:
❌ “There are low Peng, level Peng, and diagonal Peng as different techniques.”
It is better to say:
Peng can be expressed in different directions, such as low, level, or diagonal, depending on body structure and incoming force.
Or more precise:
Although classical theory defines Peng as a unified expansive energy, in practice it may manifest at different heights or angles, such as low, level, or diagonal applications.
4️⃣ Important Theoretical Clarification
Peng is not about:
Peng is about:
structural expansion
connected body alignment
internal support
elastic integrity
The direction is secondary.
5️⃣ For Your Push-Hands Manual
If you want a professional explanation, you could write:
Peng is a unified expansive energy. While it may be applied at different levels or angles in practice (low, level, diagonal), these are directional variations rather than distinct categories of jin.
That would sound internationally refined and theoretically accurate.
Excellent. Let’s go deeper — structurally, biomechanically, and theoretically — and keep it suitable for your international push-hands documentation.
1️⃣ Vertical Peng vs Diagonal Peng
(Biomechanics + Structure)
🔹 Vertical Peng
This expresses upward or buoyant expansion.
Characteristics:
Dantian slightly lifts and expands.
Spine elongates upward.
Kua remains open (not locked).
Force rises through skeletal alignment, not muscular lifting.
Biomechanically:
Ground reaction force travels:
Foot → Kua → Spine → Arm/Chest → Upward vector
Used when:
It feels like:
A column inflating vertically.
🔹 Diagonal Peng
This expresses expansion along a corner angle (四隅).
Characteristics:
Dantian rotates slightly.
One kua opens more than the other.
Structure forms a spiral line.
Expansion travels along an oblique plane.
Biomechanically:
Force vector:
Rear foot → Kua rotation → Spine spiral → Shoulder/Arm → Diagonal outward line
Used when:
It feels like:
A sphere expanding toward a corner.
2️⃣ Chest Peng vs Arm Peng
This distinction is very important.
🔹 Arm Peng
What beginners often do:
Arm expands outward.
Elbow rounds.
But torso is passive.
This is local Peng.
Problem:
🔹 Chest Peng
More advanced:
Here, Peng is not in the arm —
it is in the whole torso structure.
When force comes:
It is:
Whole-body Peng expressed through the chest.
This is why in retreat:
You first establish chest Peng → then contain → then transform into Lu.
3️⃣ How Peng Transforms into Ji and Kao
This is the most important dynamic relationship.
Peng is not separate from the others.
It is the base elastic structure.
🔹 Peng → Ji
Ji (Press) happens when:
Mechanically:
So:
Ji is compressed Peng.
Without Peng:
🔹 Peng → Kao
Kao requires:
When Peng expands through torso,
and you rotate and enter,
that expansion becomes body strike.
So:
Kao is Peng supported by mass and rotation.
Without Peng:
4️⃣ Relationship Summary
| Energy | Structural Base | Transformation Mechanism |
|---|
| Peng | Expansive integrity | Foundation |
| Ji | Compressed Peng | Converging structure |
| Kao | Mass-supported Peng | Rotational entry |
| Lu | Dissolving Peng | Yielding spiral |
5️⃣ Unified Concept (Advanced Level)
Peng is not:
An arm technique
A height
An angle
Peng is:
Three-dimensional structural elasticity.
Low Peng, level Peng, diagonal Peng are:
directional expressions
not separate energies
Chest Peng and Arm Peng are:
Ji and Kao are:
