Péng, Lǚ, Jǐ, Àn (掤捋挤按) are the Four Primary Hands (四正手 Sì Zhèng Shǒu) of Tàijíquán. They form the first half of the Eight Gates (八门 Bā Mén) and the practical core of the Thirteen Postures (十三势 Shísān Shì). In solo form they appear as body methods and movement qualities. In Tuīshǒu (推手, Push Hands) they become a continuous exchange of receiving, redirecting, pressing, and returning force.

These four methods are often translated as Ward Off, Roll Back, Press, and Push. The translations are useful, but they can sound like isolated techniques. In Tàijíquán they are better understood as Jìn (劲) patterns: trained expressions of whole-body force.

Position in the Thirteen Postures

The Thirteen Postures combine eight hand methods with five stepping methods. The eight hand methods are divided into two groups:

The Four Primary Hands are called "primary" because they establish the basic grammar of Tàijí contact. Before a practitioner can understand complex changes, they must learn how to maintain structure with Péng, yield with Lǚ, close with Jǐ, and return force with Àn.

They are also the foundation of many basic Push Hands patterns. A partner gives pressure; the practitioner receives it without collapsing, leads it away, enters through the opening, and returns force while maintaining center. This cycle is simple in outline but deep in practice.

Péng (掤) — Ward Off

Péng is the expansive, buoyant quality that prevents collapse. It is often translated as Ward Off, but it is not a stiff block and not a muscular shove. Péng is the rounded structural fullness that allows the body to receive pressure and remain intact.

The image is a ball filled with air. When pressed, it does not become rigid; it expands evenly and returns pressure through its whole shape. In the body, Péng comes from the feet, legs, waist, spine, and arms working as one connected frame. The arm may be the point of contact, but the power does not belong to the arm alone.

In practice, Péng trains:

• rounded structure without stiffness
• expansion from the center rather than the shoulders
• rootedness under incoming pressure
• connection from the feet to the hands

Without Péng, the arms collapse, the chest tightens, or the shoulders rise. With Péng, the body can stay open and responsive even when another person applies force.

Lǚ (捋) — Roll Back

Lǚ is the yielding and redirecting method. It receives incoming force and leads it past its target. The body does not retreat in fear and does not resist head-on. It turns, sinks, and changes angle so that the opponent's force meets emptiness.

Lǚ depends on listening. The practitioner must feel where the pressure is going before redirecting it. If the movement is too early, it becomes escape. If it is too late, the body is already jammed. Correct Lǚ follows the opponent's direction just enough to guide it away.

The waist is essential. A common beginner error is to pull with the arms. Real Lǚ uses waist rotation, weight shift, and relaxed contact. The hands guide, but the center does the work.

In practice, Lǚ trains:

• yielding without collapsing
• redirecting through angle rather than strength
• maintaining contact while changing direction
• distinguishing substantial and insubstantial

Jǐ (挤) — Press

Jǐ is a focused forward pressure. It is often translated as Press or Squeeze. After Lǚ has led the opponent's force away, Jǐ enters through the opening with unified structure.

In many basic patterns, Jǐ is expressed through both arms working together. One arm forms the main contact while the other supports it, allowing the force from the legs and waist to concentrate through a clear line. The feeling is not a broad push. It is more like closing space with a connected frame.

Jǐ requires correct timing. If applied before the opponent's force has been neutralized, it becomes a contest of strength. If applied after the opening has disappeared, it arrives too late. Correct Jǐ appears when the opponent's structure has already begun to empty.

In practice, Jǐ trains:

• closing distance without leaning
• issuing through connected structure
• using both arms as one frame
• finding the line of pressure through the opponent's center

Àn (按) — Push

Àn means to press or push downward. In Tàijíquán it is not simply pushing someone away with the hands. Àn first sinks and settles, then returns force through a rooted, wave-like expression.

The downward quality is important. The practitioner does not lift the shoulders or drive forward from the upper body. The force sinks into the legs, passes through the waist, and returns through the hands. This can feel like pressing water: the surface lowers, then rises and moves forward as one body.

Àn often completes the basic cycle after Jǐ. Where Jǐ closes and concentrates, Àn settles and releases. In Push Hands, this can uproot the partner if their center has already been compromised.

In practice, Àn trains:

• sinking before issuing
• keeping the shoulders and elbows heavy
• returning force from the root
• applying pressure without losing central equilibrium

The Cycle of the Four Hands

The Four Primary Hands are often trained as a cycle:

This cycle is a training pattern, not a fixed formula for fighting. It teaches how force changes: expansion becomes yielding, yielding creates the opening for pressing, pressing transforms into sinking and issuing, and issuing returns to contact.

As skill develops, the four methods no longer appear as separate steps. Péng is present inside Lǚ. Lǚ can contain the beginning of Jǐ. Àn requires Péng structure to avoid collapse. Each method depends on the others.

Relationship to Form Practice

In solo form, Péng, Lǚ, Jǐ, and Àn are hidden inside many movements. The visible choreography may show a turn, step, palm, or closing action, but the internal question is always: what Jìn quality is being trained?

A movement with rounded expansion may be training Péng. A turn that receives and leads may be training Lǚ. A closing frame may express Jǐ. A sinking double-hand action may express Àn. The same external posture can contain different meanings depending on timing, direction, and intention.

For this reason, form practice should not be reduced to memorizing shapes. The shape is the container; the Four Primary Hands help give it martial meaning.

Relationship to Push Hands

Push Hands makes the Four Primary Hands testable. A practitioner may believe they are relaxed, rooted, and connected in solo form, but partner pressure reveals the truth quickly.

In Tuīshǒu, Péng prevents the structure from collapsing on contact. Lǚ teaches how to yield without losing connection. Jǐ teaches how to enter when the partner becomes empty. Àn teaches how to return force without leaning or forcing.

The goal is not to overpower the partner. The goal is to understand pressure, angle, timing, and center. When the four methods are trained correctly, the practitioner learns to avoid meeting force with force. Instead, force is received, changed, and returned through the whole body.

Common Errors

Turning Péng into stiffness. Péng must be full but alive. If the shoulders rise, the elbows lock, or the chest hardens, the structure becomes rigid and easy to control.

Pulling Lǚ with the arms. Lǚ comes from the waist and stepping method. Arm-pulling breaks connection and usually exposes the practitioner's own center.

Leaning during Jǐ. Pressing forward with the torso sacrifices root. Jǐ should close through the legs and waist while the spine remains upright.

Pushing Àn from the shoulders. Àn begins by sinking. If the shoulders push first, the force is local and easily redirected.

Practicing the cycle mechanically. The sequence is a learning tool. Real skill comes from feeling when each method is appropriate, not from repeating the names in order.
