Master Yan’s Method of Receiving and Issuing Force
顏老師的接勁與發勁
1. Maintain upright alignment and sink the whole body
全身中正、鬆沉下坐、鬆腰落胯，重心落腳跟
Keep the entire body upright and properly aligned（中正）. Relax and allow the body to sink（鬆沉）, as though sitting gently downward（下坐）. Release the waist（鬆腰）and let the kua—the hip and inguinal joints—drop naturally（落胯）.
Let the body weight settle toward the heels（重心落腳跟）, but do not lean backward or lift the toes. The soles should remain in contact with the ground so that the stance stays stable, sensitive, and ready to move.
2. Release the tailbone and connect the force to the hands
尾閭再鬆下，有上鉤之感，貫串到手
Relax the tailbone and sacral area further downward（尾閭鬆下）. At the same time, there is a subtle sensation of the tailbone curving or hooking slightly upward（上鉤之感）.
This is not a forced pelvic tuck. It is an internal adjustment that lengthens the lower back and helps connect the entire body. The force then travels continuously from the feet, through the legs, kua, waist, spine, shoulders, arms, and finally into the hands（貫串到手）.
3. Let the fingers lead the intention and issue force
手指領意，發勁
The fingers guide the intention（手指領意）and indicate the direction in which the force is issued. The hand does not act independently. Once the whole body is connected, the fingers lead and the integrated force of the entire body is released through the hands（發勁）.
The sequence may be understood as:
Receiving the Partner’s Force While Moving
接勁與全身移動
When Master Yan receives the partner’s incoming force—sometimes described as “receiving the ball”（接球）—the whole body moves as one integrated unit（全身整體移動）.
Whether advancing（前進）or retreating（後退）, the body must remain upright and centered（全身保持中正）. One should not bend at the waist, lean forward, lean backward, or allow the upper body to move separately from the lower body.
The essential idea is:
Receive the force with the whole body, redirect it through the waist and kua, and never resist with the arms alone.以全身接勁，以腰胯化勁，不以手臂硬頂。
Advancing with a Large Step
進大步
A large advancing step（進大步）allows you to apply force over a longer distance（按較長距離）. However, the supporting leg and stepping leg must have sufficient strength and stability（腳需有力）.
The step should not cause the body to rise, fall suddenly, or lose its central alignment. The torso remains upright while the lower body carries the whole structure forward.
Pivoting the feet is the main mechanism
以碾腳為主
Advancing with a large step depends mainly on pivoting or grinding the feet against the ground（碾腳）. The feet rotate in coordination with the knees, kua, and waist, allowing the whole body to change direction and advance without twisting the knees.
The movement should be driven by the ground and coordinated through the whole body:
Four-Square Push Hands
四正推手
The principal techniques are:
Peng（掤）: Ward off—maintaining an expansive, rounded structure.
Lü（捋）: Roll back—receiving and redirecting the partner’s force.
Hua（化）: Neutralize—transforming the incoming force so that it loses its effect.
An（按）: Press—issuing force forward or downward through both hands.
Ji（擠）: Squeeze or press—concentrating force toward the partner’s center.
In the standard Four-Square Push Hands sequence（四正推手）, the four primary energies are usually Peng, Lü, Ji, and An（掤、捋、擠、按）, while Hua（化） is the neutralizing quality used throughout the entire exercise.
The central principle is:
Receive with Peng, redirect with Lü, concentrate with Ji, and issue with An. Neutralization is present within every movement.
Two-Person Practice of Peng, Lü, Hua, An and Ji
雙人掤、捋、化、按、擠練習法
The partners are called Partner A（甲方） and Partner B（乙方）. Begin slowly, maintain light contact, and practise both left and right sides.
1. Peng Practice — Ward Off
掤勁練習
Partner A（甲方） places one or both hands lightly on Partner B’s arm and gradually applies forward pressure（向前按入）.
Partner B（乙方） relaxes the shoulders and elbows（鬆肩沉肘）, sits into the kua（落胯）, and maintains an expanded, rounded structure（掤圓）.
B receives the pressure through the whole body rather than resisting with the arm.
The incoming force is connected through B’s arm, back, waist, legs, and feet.
Key point: Peng is not muscular pushing. It is an elastic, whole-body supporting force（整體彈性支撐力）.
The arm makes contact, but the feet receive the force.手臂接觸，腳底承勁。
2. Lü Practice — Roll Back
捋勁練習
Partner A applies forward pressure toward B’s centre（進按）.
Partner B first receives the force with Peng（以掤接勁）.
B then relaxes the waist and kua, turns the body, and guides A’s force diagonally past the body（轉腰落胯，引勁落空）.
B keeps light contact with A’s wrist and elbow, without pulling only with the arms.
The whole body turns as one unit while remaining upright（中正整體轉動）.
Key point: Do not drag the opponent sideways. Follow the direction of the incoming force and add only a small guiding action.
Follow the force, change its direction, and lead it into emptiness.順其來勢，改其方向，引進落空。
3. Hua Practice — Neutralize
化勁練習
Hua（化） is not a separate fixed hand technique. It is the skill of dissolving or transforming the partner’s force and is present within Peng, Lü, Ji, and An.
Partner A presses slowly toward B’s centre.
Partner B maintains contact without resisting or withdrawing suddenly.
B releases the waist and kua（鬆腰落胯）, adjusts the tailbone（尾閭鬆下）, and shifts or turns the whole body.
B keeps the torso upright while allowing A’s force to pass beside or through an empty space（化開來力）.
After neutralizing, B remains balanced and ready to counter.
Hua may be practised through:
Turning neutralization（轉化）: turning the waist and kua.
Sinking neutralization（沉化）: relaxing and sinking the force toward the ground.
Stepping neutralization（走化）: advancing, retreating, or turning the feet.
Opening neutralization（開化）: opening the body’s angle to create emptiness.
Key point: The purpose is not merely to escape. After neutralizing, you should remain connected and occupy an advantageous position（化中有接，化中有進）.
4. An Practice — Press
按勁練習
After B uses Lü or Hua to neutralize A’s force, B places both palms lightly on A’s torso or arms.
B first settles and connects the whole body（鬆沉貫串）.
The fingers lead the intention（手指領意）.
B advances through the feet, legs, kua, and waist, issuing force through both palms.
The palms may press forward, slightly downward, or forward and upward according to A’s balance.
For a longer press（長距離按）, B may advance with a larger step（進大步）:
Pivot the feet（碾腳）.
Open and move the kua（開胯、進胯）.
Keep the torso upright（保持中正）.
Move the whole body forward as one unit（整體前進）.
Key point: Do not push first with the hands. The hands arrive together with the movement of the whole body.
The body advances, the hands follow, and the force reaches the partner through the palms.身進、手隨、勁達掌根。
5. Ji Practice — Squeeze
擠勁練習
After receiving and neutralizing A’s force, B places one forearm or the back of one hand against A’s body or arm.
B’s other palm supports or presses against the inside of the first forearm or wrist.
B maintains a rounded structure and keeps the elbows relaxed.
B closes the space through the coordinated action of both arms and the whole body（兩臂合勁）.
The feet and legs drive, the waist directs, and the two arms concentrate the force toward one point.
Ji can also be practised when both partners’ arms are crossed. B uses the contact point to concentrate force toward A’s centre（集中一點，擠向中線）.
Key point: Ji does not mean squeezing only with the arms. It is the convergence of two directions of force supported by the whole body（兩勁相合，集中發出）.
Continuous Two-Person Sequence
雙人連續練習
A simple continuous pattern is:
A presses（甲按） toward B.
B receives with Peng（乙以掤接）.
B uses Lü and Hua（乙捋化） to redirect A.
B counters with An（乙按）.
A receives with Peng（甲掤接）.
A uses Lü and Hua（甲捋化）.
A counters with Ji or An（甲以擠或按反擊）.
Both partners continue, repeatedly exchanging the attacking and receiving roles.
This creates a continuous cycle:
In traditional Four-Square Push Hands（四正推手）, the principal sequence is commonly:
Peng, Lü, Ji, An（掤、捋、擠、按）
Hua（化） runs through every transition. Therefore, it may be taught as:
Peng receives the force; Lü and Hua redirect it; Ji closes and concentrates it; An sends it out.掤以接勁，捋化以引勁，擠以合勁，按以發勁。
