Yiquan意拳

What Yiquan is, where it comes from, and what sets it apart from other martial arts.

„Training of forms has been popular for long time, but actually it is something harmful, leading people astray."— Wang Xiangzhai, Essence of Combat Science (~1940)

The name and its history

Wang used the name Yiquan from the mid-1920s onwards (attested from about 1926). Dachengquan appeared in 1939/40: Zhang Yuheng (Zhang Bi), a friend and supporter of Wang's, coined the name and made it public in Beijing through a newspaper article on 2 April 1940. Wang found “great accomplishment” presumptuous and returned to Yiquan in 1947:

„Knowledge really has no end. How then can we call it 'Great Accomplishment'? There is no finishing point."— Wang Xiangzhai

Two aims, one foundation

The same standing practice is distinguished by purpose: Yang Sheng Zhuang (养生桩, health cultivation) and Ji Ji Zhuang (技击桩, combat). Both rest on the same principles; the martial art is built on the health work. Wang always taught visitors Yang Sheng Zhuang first.

“Practice is cultivation, and cultivation is practice.”— Wang Xiangzhai

Six philosophical roots

„Learning yiquan without it's philosophy will not bring proper results."— Wang Xiangzhai, Essays 1940

Yiquan training is a linear progression from the static to the dynamic and from solo practice to combat application — carried throughout by the same principles.

Every stage carries the same force into a new domain. Fa Li is both synthesis and hinge: “Fa Li is the synthetic expression of Zhan Zhuang, Shili and Mocabu” (Yao Chengguang). Without Fa Li, Tuishou and Sanshou remain technically sound but lack explosive power.

Constant principles — the same at every stage

The chain of learning according to Yao Chengguang

„In combat science we start from zhan zhuang. Through shi li we learn to know it, in fa li we use it, thanks to tui shou we understand it, with shi sheng we can strengthen it, in san shou we learn all the variability of changes."— Yao Chengguang, Yiquan Essays

The maxim of the whole system: “Zhan Zhuang is the basis, Shili is the key.”

The physical foundation

Beneath the work with intent lies sober mechanics: fighting force is trained bodily force (劲 jìn = 力 lì, not 气 qì) and draws on the ground reaction force (Newton’s actio = reactio). The force runs from the ground along the chain leg → hip → trunk → hand. This is not a doctrine of Wang’s or Yao’s — neither of them cites Newton anywhere. It is, however, the mechanical foundation of demystification: “the phenomena are all verifiable”.

A – D

Action and ReactionPhysics · Background

Newton’s third law as a mechanical foundation — background, not doctrine (neither Wang nor Yao cites Newton): forces occur in pairs on two bodies, and for exactly that reason they do not cancel out. The most important form is the ground reaction force — the foot presses against the ground, the ground drives the body; force begins at the ground and runs along the chain leg → hip → trunk → hand (Shenfa, Fa Li). In fighting: take up the opponent’s impulse on the diagonal instead of blocking it (Shun Li Ni Xing). Cleanly distinguished: external force pairs (ground, opponent) accelerate the centre of mass and issue force; internal ones (六面争力, co-contraction of the antagonists) cancel out externally and produce only elastic pre-tension — the “taut ball” (Hun Yuan Li). It underpins the demystification (拳学是科学).

External Connections 身外争力 / 假借Principle · Practice

External connections (身外争力, “contending force outside the body”; the tool for it is “borrowing”, 假借) are the counterpart to the internal connections (身内争力). What is meant are the lines of force projected outward into the distance through the intent, between the body and distant objects in the surroundings: threads or springs running from the fingers to a far-off tree, to the horizon, to the air, or to an imagined opponent. Where the internal connections couple one part of the body to another, the external ones couple the body to the outside world. The tool is Jiajie (假借, “borrowed imagination”): external anchors that are not there are treated in the Yi as real, and from them one “borrows” force (假借之力). The model case is Gou Gua (勾挂, “hook and hang”): springs run out to the distant tree — moving forward one compresses them, and with the hooks of the fingers one draws them back; the force lives in the taut line between hand and distant anchor, not in the arm alone. This is how 宇宙争力 arises (the contending force between body and surroundings) — the external force pair alongside the internal pre-tension. With it grows the mature aim of being “merged with every part of the surroundings”: the force does not end at the palm but reaches out into space (the basis for Fa Li through the target and for the sense of distance in Sanshou). Not to be confused with the three external harmonies (外三合) of the Six Harmonies (六合), which are mere coordination of the limbs.

Monkey Form 猴形 / 猿猴攀藤Solo exercise · Animal form

The monkey form comes from the twelve animal forms of Xingyiquan and is the best-attested animal trace in Yiquan — on two levels. As a solo exercise: 猿猴攀藤 (“the monkey climbs the vine”) belongs to the repertoire of the solo exercises. Both hands circle in parallel from the thighs up to the face while the body squats down and rises again. What is trained is mobility in rising and sinking — and what holds for every solo exercise holds here: the shifting of the body must work harder than the hands. In application (“ghost drilling hand”, 鬼扯钻) one props the opponent’s extended hand aside and attacks in the same movement: his arm is the vine the monkey climbs. That the exercise comes from the monkey form is not a retrospective construction — Bo Jiacong derives it that way explicitly in his instructional film. In the founder: the image is older still. Already in his combat manuscript of 1959 Wang Xiangzhai lists the monkey among the four animal forms of the eight-method model fist (Ba Fa). What matters is how the same verse ends: 仿生无形学其力 — “imitate the living thing without its form: learn its force.” What remains of the animal is the quality of its force; the shape falls away (demystification).

Agonist / AntagonistBiomechanics

Opposing pairs of muscles at a joint — flexor (agonist) and extensor (antagonist). Their simultaneous, weak activation is called co-contraction, and in Yiquan it is the physiological basis of Hun Yuan Li: flexors and extensors work gently against each other, so that the body is elastically pre-tensioned and joined into a unit (the image of the “taut ball”). As an internal force pair, the antagonists’ pulls cancel one another outwardly — they produce no acceleration, but joint stiffness and pre-tension. In this way Zheng Li / 六面同时 does obey the principle of interaction (Newton’s third law), yet stays internally bound. Mo Jin is what first makes this co-contraction perceptible (level 2: “finding the surroundings”).

BreathingPrinciple

“The bridge that joins the body to nature.” The basic rule: breathe entirely naturally — neither lengthening the breath nor holding it. It develops in three steps: natural breathing → deep abdominal breathing that arises of its own accord (“the qi sinks to the dantian”) → and at the highest level, “forgetting that one breathes”. Exhalation strengthens the parasympathetic system and deepens relaxation. The image: a sea turtle swimming calmly in the depths.

Ba Fa 八法Founder’s system

The “eight methods” (提顿吞吐沉托分闭) from Wang Xiangzhai’s combat manuscript (拳谱, 1959). Part of his late system, which unfolds in stages: out of the six forces (六力) come the eight methods, and from them nine types of fist (九拳型), twelve animal-inspired fists (十二仿生拳) and 56 model fists (模式拳). A clarification from the founder: 蠕动 (worm-like micro-movement) is not 不动 (motionlessness) — a confusion handed down through mishearing.

Baguazhang 八卦掌Internal martial art · Context

Baguazhang (八卦掌, “eight-trigram palm”) is, alongside Xingyiquan and Taijiquan, the third of the internal martial arts. It is recognisable by its circle walking: the practitioner walks a circular path while the body winds in a spiral against the direction of travel; the work is done with open palms rather than fists. The style becomes historically traceable from the mid-nineteenth century through Dong Haichuan in Beijing; its two main branches go back to his direct students — the soft, flowing Cheng style after Cheng Tinghua and the powerful, explosive Yin style after Yin Fu. Relation to Yiquan: Bagua is context, not root. Yiquan came out of Xingyiquan — but Bagua was the art of several men in Wang’s circle. He remembered Cheng Tinghua admiringly all his life: “truly like a divine dragon passing through the void”. His regard, however, was for the people, not the system: in his late writings Wang sketches a story of decline for Xingyi and Bagua alike. Yiquan took over neither the circle-walking choreography nor the trigram system; where it works in circles, that is the result of the contending force in Shili — the logic of force yes, the cosmology no (demystification).

Chan Si Jin 缠丝劲Neijia mechanics

Chan Si Jin (缠丝劲, “silk-reeling force”) is the winding whole-body connection of the internal martial arts — according to Mike Sigman merely another name for six-harmonies movement (六合). The body moves as one connected unit governed from the dantian, carried by ground force (Peng Jin) and gravity — “peng + connection” are the two building blocks of internal force. A distinction to keep: 缠丝劲 (winding, spiralling) as against 抽丝劲 (drawing in a straight line). The cycle of closing → opening (顺/逆 = yin/yang) is Taiji, here as body mechanics rather than cosmology. ⚠️ Not to be confused with Shun Li Ni Xing: there 顺/逆 are a principle of combat, here they are directions of winding. Yiquan trains no visible silk-reeling choreography as Chen Taiji does, but the same elastic trunk-to-fingertip substrate as its internal connections.

Chengbao Zhuang 撑抱桩Posture

“Propping and embracing post” — 撑 “to prop, to stretch outward” and 抱 “to embrace, to hold inward”: the name already states the pair of contending forces that makes up the posture. It is the basic posture of Zhan Zhuang and counts as the most essential posture of Yiquan (20–30 minutes). Stance: feet parallel and shoulder-width apart, knees slightly bent, the seat as if set on a high bench, the crown of the head drawn upward in imagination. The hands rise in front of the chest, about 30 cm from the body, palms facing inward and higher than the elbows, fingertips towards each other, two to three fist-widths between the palms; the elbows hang down. Two images not to be confused: between each finger lies a ball of cotton wool — so the fingers are neither stiffly closed nor splayed, but naturally slightly open; the arms, by contrast, embrace a balloon in front of chest and belly: too much force and it bursts, too little and it falls. Exactly this measure is the co-contraction of the opposing muscles, and thus the physiological basis of Hun Yuan Li. To this add the image of water: standing in water that carries the arms and gives resistance at every micro-movement (→ Mo Jin). As Pingbu Chengbao Zhuang it is called “the gate to Yiquan and at the same time its temple”.

Da / Fa 打 / 发Type of force

The two ways issued force takes effect: Da (striking) — short distance, small area, brief contact, penetrating effect, high risk of injury. Fa (projecting) — large area, longer contact, throws the opponent far away, low risk. “Once Fa Li is mastered, one can strike or project at will.”

Dachengquan 大成拳Name

“Fist of great accomplishment” — an alternative name for Yiquan, coined in 1939/40 by Zhang Yuheng (Zhang Bi) and made public through a newspaper article; in use until 1947. Wang rejected the name as presumptuous (“knowledge has no end”) and returned to Yiquan. Today both names are used synonymously. While the main Yao Zongxun lineage prefers “Yiquan”, the Wang Xuanjie branch carries “Dachengquan” as its own name and brand — with compendia of its own (health Zhan Zhuang, eighteen fighting forms).

Dan Cao Shou 单操手Training method

Dan Cao Shou (单操手, “hands practised singly”) is the repeated drilling of individual techniques outside free fighting. Rather than searching for a movement only in sparring, one drills it on its own until it is available as a reflex — the complement to Sanshou. The solo exercises prepare free application and then accompany it as a constant drill. The repertoire begins with loosening and axis work for head, shoulders, waist and hips. Then come the hand exercises — among them the snake-coiling hand, a basic skill of Tuishou, and the monkey form — followed by leg and stepping exercises and a separate training for the eyes. The conditioning against blows (抗击打) is no hard qigong: impacts are led away by yielding (泄力), the way one receives a thrown ball. Above all of it stands one maxim: the body works harder than the hands. The hands stay almost in place; trunk and legs carry the movement. What is trained is Shenfa and Fa Li, not fixed striking patterns.

Dan Tian 丹田Concept · disputed

“Cinnabar field”, the traditional energy centre — critically renegotiated within Yiquan. Wang used the term positively in 1928, then criticised it in the 1940s as anatomically wrong (“what is there is stomach, intestine, liver — no place for qi”). The Yao lineage reframes it: an area between the navel and Ming Men (not a point), condensed into a “motor”. Yao Zongxun: “the whole body must become a dantian.” Qi must not stagnate in the dantian but flows through the entire body.

Dingba Bu 丁八步Stance

The T-and-eight step: one foot opens to 45°, the other points straight ahead, offset outward by one foot’s width; the heel of the front foot slightly raised, about 70 % of the weight on the rear leg. “Half 丁 (ding), half 八 (ba).” It combines a stable base with quick reactivity; the basis for Shili, Mocabu, Tuishou and Sanshou.

E – J

Empty Force / Ling Kong Jin 灵空劲disputed

A “force acting without contact”, developed by You Peng Xi (with the mesmerist Le Huan Zhi) and inspired by tantric practice. Not part of standard Yiquan, and in contradiction to the main lineage (Yao Zongxun: no supernatural powers; Yiquan as a science of combat). Controversially discussed in the West.

DemystificationLeitmotif

“Martial art is science, not myth” (拳学是科学而不是神话). In his principal work (1988) Yao Zongxun rejects occult myths five times over: the empty force (空劲), killing by pressure point (点穴), “running over walls and roofs”, the doctrine of generation through the five phases, and mystery-mongering in general (神秘). This is the sharpest primary contrast to the empty-force line around You Peng Xi and Liang Zi Peng — “Yiquan” is no monolith: on 空劲 the main and southern lineages stand opposed. Put positively, mechanics supplies the sober counter-explanation: fighting force is trained bodily force (劲 jìn = 力 lì, not 气 qì), resting on action and reaction and on the ground reaction — “you need not believe me, the phenomena are all verifiable”.

Relaxation / Song 松Principle

Emphasised first in training: only in a relaxed body do qi and blood flow freely. Not going limp, but “relaxation without slackness” — the image is the tiger lying lazily in the sun, outwardly loose, inwardly full of force. Six methods: mental relaxation, a relaxed face (“almost smiling”), relaxing on the out-breath, gentle micro-movement, and active and passive adjustment of the posture.

Fa Li 发力Method · Stage 5

Explosive issuing of force — the synthesis of Zhan Zhuang, Shili and Mocabu in one sudden, whole-body impulse. Four factors: nervous activation, ground reaction, contradictory forces, and pulsation. Two phases: gathering → issuing (and straight back into relaxation).

Fang Song 放松Principle · fundamental

“True relaxation” — the mark that distinguishes real Yiquan from false: “if there’s no FangSong, there’s no YiQuan” (Yao Zongxun). Outwardly soft as dough (“like flour mixed with water, like the body of a newly born baby” — Wang), inwardly alive and full. It is the precondition for the Yi Nian to flow freely through the body, and one of the three inseparable factors of Zhan Zhuang.

FasciaAnatomy · Background

Fascia (Latin fascia, “band”) are the sheet-like connective-tissue sheaths of the muscles — in the broad reading, all collagenous fibre structures. No primary Yiquan text speaks of them; the term comes from modern explanatory models brought to bear on classical practice. Three properties touch the training directly. Deep fascia are densely furnished with proprioceptors and are thus the tissue in which Mo Jin finds anything at all. “Mo” means groping in the dark; what is groped for is one’s own proprioception, not objects — and out of that Ting Jin is sharpened. They transmit force, which therefore does not travel by muscle–tendon–bone alone. And their stiffness is adjustable rather than constant, which corresponds to the Song/Jin alternation. On this tissue Mike Sigman bases his image of the “suit”: when the centre moves, hands and feet follow through the tensile connection — the same idea that explains the outer Six Harmonies. The underlying model of continuous myofascial chains (after Ida P. Rolf) is, however, scientifically disputed: that fascia conduct and feel force is anatomy; that they do so along trainable lines remains interpretation (demystification).

Fu Hu Zhuang 伏虎桩Posture

“Subduing the tiger” — the lowest and most demanding combat posture in Yiquan. A large stance (about 60–70 cm), the front heel empty, knees bent, the seat settling; palms on the inside of the knees, fingers pointing down; weight 30/70 — here the system standard applies, unlike in Xiang Long Zhuang. Sense and purpose: (1) strong legs for atypical fighting positions — Yao Chengguang names Fu Hu and Xiang Long in one breath for this; (2) explicitly the building of force for large steps in every direction — the posture is thus the reservoir of power for the third Mocabu stage, the large step; (3) a resistance that works back: where Hunyuan Zhuang embraces a motionless tree, this posture holds down an animal that breaks out tirelessly in every direction — which makes the Mo Jin dialogical, every direction an answer to an attempted escape; (4) and with it the search for force travels from the arm into the whole body: left and right here is not an opening of the arms as in Hunyuan Zhuang but a movement of the whole body, with opening and closing taking place between the legs. The maxim: 神意足，不求形骸似 — let the spirit-intent be full; outward likeness of form is not required (Bo Jiacong). It is the counterpart in the Buddhist pairing 降龙伏虎; a Buddhist name, with the imagery transmitted from Shaolin wall paintings.

Large Step 大步Footwork · Combat principle

The large step (大步) is the third and last stage of the Mocabu progression (fixed → step → large step) — and not merely a “bigger step”. The first two stages practise even resistance (“as if through mud”); the large step deliberately breaks that continuity: the rear leg gives force suddenly, the body springs forward as though colliding with something and hurling it away. The step is twice as long as Dingba Bu, the front foot lands evenly, and the rear one restores the starting stance; it can also be practised backwards. It is therefore the point at which footwork and Fa Li merge (Zou Bu Fa Li). In Sanshou, 大步 serves to close the distance quickly — unlike the half step, which regulates it. Not to be confused with 大步桩 / 大步鹰桩 (大式桩) — that is a standing posture, not a step.

Gun Fa 棍法Weapon

The staff method — the weapons training of Yiquan and, in the Yao lineage, the only weapon practised systematically. The basic idea: the staff is the “extension of Hun Yuan Li into space” — not a weapon system of its own but the unarmed force carried over onto the staff. Wang Xiangzhai puts it in 拳道中枢: 拳成兵器就，莫专习刀枪 (“when the fist is complete the weapons follow — do not practise sabre and spear in isolation”); whoever possesses the force of the fist can wield any weapon (刀 / 枪 / 剑 / 棍) after brief instruction. The prerequisites are therefore the basic skills Zhan Zhuang, Shili, Mocabu and Fa Li. Grip: 半把杆 Ban Ba Gan (half grip) — thumb parallel along the staff, fingers only lightly closed; it protects the fingers when the opponent strikes along the edge of the staff. Two core exercises carry the Shili → Fa Li scheme over onto the staff: 摩杆试力 Mo Gan Shili (rubbing the staff against a tree, forward and back in Ding Ba Bu — inward spiralling force going forward, outward coming back) and 划杆发力 Hua Gan Fa Li (the tip of the staff glides onto the opponent’s centre line or nose, penetrating — on the spot and with a step). To these is added a two-staff partner exercise — the weapon counterpart to Tuishou.

Half Step 半步Footwork · Combat principle

The half step (半步) is not a step for getting forward but a means of regulating distance: the opponent attacks, and one goes half a step back and immediately forward again. The measure is the whole point — the retreat goes just far enough that the attack grasps at nothing, but not so far that one gives up one’s own striking distance. A full step back would let the opponent escape; the half step keeps him within range, and going forward again catches him at full extension. That this belongs to footwork and not to hand technique is stated by the maxim 脚打七分，手打三 — “the foot strikes seven parts, the hand three”. It came from Xingyiquan by way of Guo Yunshen, bound to that art’s crushing fist 崩拳; hence his byname 半步崩拳打天下 — “undefeated through the world with the half-step Bengquan”. Tradition has it that he developed it in the condemned cell, where leg irons confined him to a short step; this is not documented. The best-known application story is told by the southern lineage: when Ma Cheng Xin challenged Wang Xiangzhai and would not give up after the first exchange, Wang asked him what he had eaten — “noodles”. In the second round he struck him in the stomach with 半步崩捶, whereupon Ma vomited up those very noodles. Wang laughed: “at least you are honest.” An anecdote from a single late source, not evidence.

Hun Yuan Li 混元力Target force

“Force of the original unity” — the target force of Yiquan: elastic, explosive, available in every direction; it coordinates all parts of the body into an organic whole. Wang defines it (1928) through a syncretism of the five phases read as qualities of force: metal (hard as iron, skin like cotton), wood (bent-and-straight), water (fluid as dragon or snake), fire (explosive as thunder), earth (round, heavy, solid). “In movement, all the joints always hold the two contending forces.” Physically this six-sided counter-tension is an internal force pair (co-contraction): it obeys Newton’s third law but cancels out externally, producing elastic pre-tension rather than movement. Only the external ground reaction (与地心争力) delivers it as force.

Hunyuan Zhuang 混元桩Posture

“Embracing the tree” — the most important combat posture and the basis for Mo Jin and Fa Li. T-stance (Dingba Bu), 70 % of the weight on the rear leg; the left hand at mouth height, the right at shoulder height; the image: a giant embracing an enormous tree, with “springs” connecting hands, limbs and tree. Wang formerly called it Maodun Zhuang (矛盾桩, “contradiction posture”) — after the principle of simultaneous contending forces. Defined in 1928 as the synthesis of all the stances.

Internal Connections 身内争力Principle · Practice

Internal connections (身内争力, Shēn Nèi Zhēng Lì, “contending force inside the body”) are the practical, step-by-step training form of the internal contending force (争力). The principle of simultaneously acting, mutually opposed force pairs is translated into named connections between concrete parts of the body: finger to finger, the wrists, elbow to elbow, knee to knee and, in the stance, the diagonal “main connections” front knee to rear hip and head to front foot. Each connection is formed through the intent and given a material quality (thread, rubber band, “magnetic feeling”, steel spring) that determines how it behaves. The build-up runs in three stages: feel the connection → let it draw together and press apart while relaxed → actively press and pull while tensed, in the Song/Jin alternation. It is worked through stance by stance: parallel stance (Píng Bù), step stance (Dīng Bā Bù), friction step (Mocabu, fixed and walking) up to Shili while walking (Zǒu Bù Shì Lì), where the arm and leg connections are deliberately decoupled. Physiologically this is the co-contraction of the antagonists broken down joint pair by joint pair — the same elastic pre-tension that is sought in Zhan Zhuang as a whole-body “ball” (Hun Yuan Li) and felt out in Mo Jin.

Ji Ji Zhuang 技击桩Category

The combat standing postures (as against Yang Sheng Zhuang). All follow the same principle — Mo Jin in six directions and mixed — and differ only in the position and angle of the body, “so that Hunyuan Li can be used in any fighting situation” (Yao Zongxun). The standard weight distribution is 70 % on the rear leg; the exception is Xiang Long Zhuang (70 % forward). The combat postures too are practised in three bodily positions — standing, sitting, lying (站坐躺). This is emphatically not a makeshift for the infirm: when sitting, the feet are lifted clear of the floor, the drive from the legs falls away, and Hun Yuan Li must be carried by the Yi alone — sitting detaches the search for force from the ground reaction. What is trained is holding the whole-body force even in unfavourable positions: on the ground, lying down, under one-sided load.

Ji Yang Yi Ti 击养一体Guiding idea

“Unity of combat and health cultivation” — the guiding idea of Wang’s late period: 技击 (combat) and 养生 (health) are not opposites but two sides of the same practice. Condensed in the sentence “practice is cultivation, and cultivation is practice”. It is the reason Wang always taught visitors the health standing first.

Jiajie 假借Method

“Borrowed imagination” — the visualisation images of Zhan Zhuang and Mo Jin (standing in the ocean, embracing a balloon, a silk thread at the crown …). To be applied in pulses, never fixed permanently; chosen according to the aim of training and the state of health. At the Ji Ji posture the images change to the situation of an enemy (wild animals, powerful opponents).

Jian Wu 健武Method · Stage 8

“Health dance” — the highest stage of training: a free, dance-like synthesis of every method, “between intent and no intent”. Four classical sequences: bailing waves, swimming dragon, crane at play, startled snake.

Jin, Li and Qi 劲 / 力 / 气Basic terms · Force

Three Chinese words that in English all come out as “force”, “strength” or “energy” — and the difference between them explains why Yiquan is not qigong. 力 Li is ordinary strength, the kind with which you lift a suitcase. 劲 Jin is shaped force: it begins at the ground, runs through the connected body and is directed by the intent. Everyone has Li; Jin has to be earned. And it is not an energy but a skill; in someone who is tense, Jin decays back into Li. 气 Qi, finally, is the term on which Yiquan contradicts tradition most plainly: where Chinese medicine sees a circulating life energy, Yiquan means something tangible — the breath, the warmth that appears of itself during standing, or the forces present in things: the ground, gravity, air resistance. In short: fighting force is trained bodily force — 劲 = 力, not 气 (demystification). This is why the target force of Yiquan is called Hun Yuan Li and not “Hun Yuan Qi”. ⚠️ The southern lineage around You Peng Xi sees this differently and practises the “empty force” (空劲, empty force).

BonesAnatomy · Background

Bones (Latin os) are “organs resistant to both compression and tension” — and in Yiquan both matter. Their compressive strength carries the load and conducts the ground reaction force upward (action and reaction); their tensile strength makes the tendon insertion zones load-bearing, where the chain muscle–tendon–bone closes. This is the anatomy behind the Song maxim “the bones support, the flesh sinks down”, and behind the metal quality of force in Hun Yuan Li: “bones and muscles hard as iron or stone; skin and flesh like cotton”. For Zhan Zhuang what counts above all is Wolff’s law of transformation: the trabeculae of the internal scaffold always lie along the actual lines of compression and tension, and bone is “no rigid structure” but in permanent remodelling. Holding under load is therefore precisely the stimulus to which the skeleton answers structurally — which is what gives the talk of “biomechanical reshaping” in Mo Jin its sense. Organically, bone consists 95 % of type I collagen, the same protein as the fascia; it is, in a manner of speaking, mineralised connective tissue. What is established is that loading shapes the architecture — not that static standing suffices for it, or protects against osteoporosis.

L – S

Liu Mian Tong Shi 六面同时Highest stage

“Six directions at once” — the summit of Mo Jin: no preferred point of reference, all six directions tensed simultaneously, the body “as if merged with everything on earth”. The level aimed at is a conditioned reflex: contact = immediate discharge of force. Wang: “on the whole body there is no place without a spring.” Yao Zongxun: “the entire body is as if fully electrically charged.”

Maodun Zhuang 矛盾桩Posture

The “contradiction posture”: opposed forces between front and back generate the contradictory force (矛盾力). The fourth of Wang Yufang’s 31 forms, documented photographically. It illustrates the basic principle of simultaneous contending forces out of which Hun Yuan Li arises.

Ming Men 命门Concept · Body

“Gate of life” — a point on the rear midline between the kidneys (lumbar vertebrae L2–L3). In Yiquan it has two functions that must be kept apart. Anatomically and structurally it is the alignment hinge of the lumbar spine — “opening the Ming Men” (tucking the pelvis, chin in, crown up) flattens the lordosis and turns the trunk into a path for transmitting force (Zhan Zhuang). Energetically it is the rear wall of the dantian understood as an area (navel ↔ Ming Men, in the Yao lineage; Yang Shen Zhuang as the posture in which qi sensation appears fastest). As with the dantian, the modern reading shifts the emphasis from a mystical energy point to a functional hinge (demystification).

Mo Jin 摸劲Method · Stage 2

“Feeling for the force” — the micro-transition between Zhan Zhuang and Shili: minimal movement within the posture, feeling the resistance of the imagined tree in six directions. Three levels: finding the body → finding the surroundings → finding the Hunyuan.

Mocabu 摩擦步Method · Stage 4

“Friction step” — the footwork of Yiquan: the feet move as though through mud, the soles almost brushing the ground. The images of the “iron cylinder” and of running “on rails” describe a body that carries the ground reaction without loss. Three stages: fixed step → Zoubu → large step.

MusculatureAnatomy · Background

Musculature (Latin musculus, “little mouse” — a tensed muscle moves under the skin like a mouse). Physiologically, Zhan Zhuang is an isometric contraction: “force increases while the length of the muscle stays the same” — Yu Yong Nian’s image of an engine idling (the two kinetics) thus lands on a technical term. Shili, by contrast, is auxotonic: force and length change together, only very slowly. What Yiquan calls contending force is physiologically the interplay of antagonists — Zheng Li is the deliberate co-activation of an agonist–antagonist pair, out of which Hun Yuan Li arises. That a muscle can contract no further once its counterpart is maximally stretched (passive insufficiency) explains mechanically why one never works in end positions — the elbow stays at 90° or more. The muscle spindles, as stretch receptors, complement the fascia as the substrate of proprioception; the outer sheath of the muscle (the epimysium) is itself a fascia, and the two tissues are nested within one another. Two reservations remain: Yu Yong Nian’s division into “working” and “resting” muscles is his own teaching model — myology knows fibre types, motor units and functional roles, but no class of muscle that rests in everyday life. And isometrically no mechanical work is done; the rise in pulse and warmth during standing is metabolic, not mechanical.

Patting System 拍打艺术Cool-down

A tapping method used after Zhan Zhuang, transmitted by Wang Yu Fang (Wang’s daughter): the energised hands tap along the meridians (neck → shoulders → arms → chest → legs → stomach) with four fist shapes (dragon, tiger, phoenix and leopard fist). It regenerates tissue and clears the micro-traumas of long standing practice. It was once regarded as “secret knowledge”.

Peng Jin 掤劲Type of force

Peng Jin (掤劲, “ground-path force”, Mike Sigman) is the fundamental force of the internal martial arts: the solidity of the ground conducted through the connected body from the foot into the hand. The classical formula: force “begins in the feet, is directed by the waist and expressed in the hands”; the Yiquan mnemonic verses say the same — 力从足生 (“force springs from the foot”), 消息全凭后足蹬 (“everything depends on the push of the rear foot”). In Yiquan, Peng is the external, ground-reactive side of the contending force (与地心争力): what the body stores as elastic pre-tension is delivered as force along the Peng path (→ action and reaction, Fa Li). Unlike Taiji, Yiquan keeps no separate Peng “register of jin” (掤捋挤按), but the thing itself — rooting plus whole-body ground force — is identical, and part of Hun Yuan Li. ⚠️ Not to be confused with merely “bracing the rear leg”: the force of that goes almost entirely forward instead of being balanced on six sides — the opposite of the 六面争力 balance.

Pingbu 平步Stance

The parallel stance: feet parallel, shoulder-width apart. The starting position for the basic standing and for most Shili exercises; the weight distribution is typically 50/50 to 60/40.

ProprioceptionBiomechanics · Perception

Proprioception (“the body’s perception of itself”) is the sense of one’s own position, tension and movement in space — fed by receptors in muscles, tendons, joints and fascia, and evaluated by the nervous system. In Yiquan it is the perceptual foundation: the whole of the training aims not at outward form but at feeling inward. This is exactly what Mo Jin gropes for — “Mo” (groping in the dark for something unknown) means groping for proprioception inside the body, not for physical objects. The first of its three levels, “finding the body”, is pure proprioception: learning to feel the force of skin, flesh, tendons and bone (at first as pulling, warmth, numbness or swelling — the normal signs of biomechanical reshaping). Only on this basis do level 2 (sensing the imagined surroundings) and level 3 (the six-sided contending force / Hun Yuan Li) become accessible. The co-contraction of the antagonists too — the “fully inflated balloon” pre-tension — is first experienced proprioceptively. The sense is trained primarily in silent Zhan Zhuang and in the Song/Jin alternation, and tested in movement in Shili. Proprioception is thus the demystified, physiologically graspable reverse side of notions traditionally described as “feeling the qi” (demystification).

Qi 气Philosophy · TCM

Qi (气, “life energy / breath”; literally, to begin with, vapour or breath) is the most many-sided term in Chinese philosophy and medicine. As the middle of the Three Treasures (三宝), qi stands between jing (精, essence) and shen (神, spirit): 精 → 气 → 神 — the material essence refines into circulating energy, whose finest manifestation is the spirit. Qi is the term Yiquan demystifies most strongly: depending on context, 气 means (1) breath and trunk work (内练一口气 → breathing, Shi Sheng), (2) the warmth and circulation that arise naturally during standing, (3) the “energy in things” (ground, gravity, air → Peng Jin). For the decisive distinction — fighting force = jin (劲 = 力), not qi — see Jin, Li and Qi; the main lineage rejects the far-acting 空劲 (“empty force”) as mystification.

Qi Miao Fa Men 七妙法门Early form

“Seven wondrous methods” — an early form of the later seven-stage chain of training, attested in the Shanghai maturity or Dachengquan period.

Quan Fa 拳法Striking technique

The striking techniques of Sanshou — four types of fist (Bu-Zhi-De-Zhi / Zuan / Zai / Heng Quan), practised on the spot, with a step and at a run (Paobu Quan). A distinction is drawn between 打 (penetrating striking) and 发 (projecting). It goes back to Yao Zongxun’s integration of Western boxing into Yiquan.

Quan Shen Li Yi 全身力一Principle

“The whole body is (as) one force.” An expression of whole-body coordination: every partial force in the body is only a part of the total force that arises (全 whole · 身 body · 力 force · 一 one). Closely related to the 如 criterion 体整如铸 (“as if cast in one piece”) and to Hun Yuan Li.

Rou Shou 柔手Term

“Soft hands” — Wang’s early term (1939) for partner sensing: “a method of getting to know your own and opponent’s center”. Later sources and Yao Zongxun use Tuishou; most likely a development of terminology with identical content.

San Ti Shi 三体式Xingyiquan · Basic stance

San Ti Shi (三体式, “three-body posture”) is the basic and mother stance of Xingyiquan — the martial art out of which Wang Xiangzhai developed Yiquan; there it counts as the starting and finishing position of every technique. “Three bodies” refers to the triad of heaven, earth and humanity (天地人) and, transferred to the body, to its three sections: head, trunk and legs. Sun Lutang coined the sentence 万法出于三体式 — “the ten thousand methods all spring from San Ti Shi” — and called it “the gate of the method”. Structure: a three-seven step in T-position, roughly 60–70 % of the weight on the rear leg (to absorb impact and retreat quickly); the front hand extended, the rear one lower towards the belly, the spine upright, shoulders and elbows sinking. It is practised above all standing, as a “model” of force and structure on which every technique is built. Relation to Yiquan: Guo Yunshen essentially taught the young Wang a single combat posture of this type. From standing practice in its principles of force Wang developed the formless Zhan Zhuang: he kept the standing and the logic of force but discarded the fixed position in favour of freely adjustable ones — and with it the five-phase cosmology as a system of combat (demystification). San Ti Shi is thus a direct ancestor of the Yiquan basic stance.

Sanshou 散手Method · Stage 7

Free fighting (also Duan Shou, “breaking hands”) — the crystallisation of every training method and the direct test of one’s skill.

Six Harmonies 六合Principle

An ordering principle inherited from Xingyiquan: three internal and three external “harmonies” (三合). The inner three (内三合) are the mental chain 心 (heart) → 意 (intent) → 气 (qi) → 力 (force). The outer three (外三合) coordinate the outer frame: 手与足 (hand and foot), 肘与膝 (elbow and knee), 肩与胯 (shoulder and hip) — when the hand moves, the foot follows, and the body moves as a unit (形曲力圆). Still named explicitly in Wang’s first book 《意拳正轨》 (1928) — together with the warning: “the six harmonies tempt one to emphasise the parts rather than the whole — that does harm.” The principle thus fits into the reform: the breakdown into pairs of joints and of mental faculties is mere teaching scaffolding; the aim remains the undivided Hun Yuan Li (→ demystification). Not to be confused with the internal connections (身内争力, pairs of contending force within the body), nor with the external connections (身外争力, connections projected into the distance) — 外三合 means the coordination of the limbs alone.

TendonsAnatomy · Background

Tendons (Latin tendo) join muscle to bone — but they can also attach to fascia, and tendon, fascia and the organic substance of bone consist primarily of the same type I collagen. The continuum customary in Yiquan — “skin, flesh, tendons, bone”, along which the first level of Mo Jin gropes — therefore describes differently condensed forms of one building material, not four separate tissues. For training, two properties count. The tendon is a spring: the Achilles tendon contributes up to 35 % of the energy return, and in the push-off phase almost all the stretch energy comes back. This gives the image of the body as “one elastic tendon” (Song/Jin) a physiological counterpart — and gives Fa Li a store. And it is trainable, but slow: twelve weeks of isometric training raise tendon stiffness by around 57 %, with the duration of the hold being decisive — only 20-second holds worked, one-second impulses did not. It becomes measurable only after about two months, because collagen turns over more slowly than muscle protein. Long sustained loading is therefore the effective stimulus — which is what Zhan Zhuang does. With the reservation that the studies work at 70–90 % of maximal force while standing is low-intensity — the form of contraction and the duration match, the intensity does not. As a sense organ the tendon carries the Golgi tendon organ, which measures tension, while the muscle spindle of the musculature measures length — and for Ting Jin, tension is the decisive quantity (→ proprioception). That tendons have few blood vessels and therefore regenerate poorly gives the maxim “slow and fine, never hurried” a solid justification.

Shen 神Philosophy

Spirit, consciousness, animating presence — in Chinese philosophy and medicine one of the “Three Treasures” (三宝): jing (精, essence) → qi (气, energy) → shen (神, spirit), a chain of refinement. The classical image: when jing is full and qi is strong, the shen shines brightly — visible above all in the lustre of the eyes (眼神). In the model of the “five shen” (五神, Huangdi Neijing), shen dwells in the heart and is the “emperor” over four subordinate aspects — one of which is Yi (意). In Yiquan it appears mostly in compounds: 神意足 (“spirit-intent full”), 精神 (mental force), 凝神 (gathering the spirit) — fitting the principle that “the spirit leads, the force follows”. Not to be confused with 身 (“body”, → Shenfa) or 生 (“voice”, → Shi Sheng): the same transcription, different characters.

Shenfa 身法Principle

“Body method” — the art of moving the body as a whole: force begins at the ground, runs through hip and trunk and discharges in the hands. “Body like a hammer, arms like nails.” The hands follow the movement of the body passively; trained through Yaofa and Xuanfa Shili in Dingbabu. In fighting: changing position within the attack, unexpected angles.

Shi Sheng 试声Method

“Testing the voice” — issuing voice and force in the same instant, so as to reinforce Fa Li reflexively. The sound comes from within (from the belly and diaphragm), not as a shout at the opponent (Wang: “like a voice in a silent valley, like a bronze bell”). Two sounds are used — “Yi” and “You/Yao” — in three stages: (1) each separately, hoarse and muffled; (2) joined (Yi-You Tong Sheng, “as if a great stone fell into a well”); (3) with no audible sound — only intent and force.

Shili 试力Method · Stage 3

“Testing the force” — the key of the method: it carries the force built up statically over into slow, controlled movement. “The testing of force is the source of true force.”

Shun Li Ni Xing 顺力逆行Combat logic

“Flow with the force, travel against the current” — the paradoxical logic of fighting: receive the attacking force instead of blocking it (Shun Li) and in the same instant use its momentum to destabilise (Ni Xing). Six advantages, among them an exponentially increased potential of force and a response free of the 0.2-second muscular delay. It also underlies Mo Jin. Mechanically: use the momentum of the attack rather than blocking it with counter-force.

Si Ru Jing Jie 四如境界Founder’s system

The “state of the four likenesses” — the highest of the three standing levels (Zhan Zhuang) and the precondition for practising the Four Forms. At the same time four criteria of perception that include one another and hold simultaneously; for advanced practitioners they are indispensable. Four sensations: 身如铅灌 (the body as though filled with lead — relaxation and rooting, force condensed inward yet light) · 体整如铸 (the body as if cast in one piece — coordinated total force, cf. 全身力一) · 肌肉如一 (the muscles as one) · 毛发如戟 (the hair standing up like halberds). In this state Hun Yuan Li arises (浑元争力). Wang Xiangzhai maps the standing levels onto the three 境界 of the scholar Wang Guowei. Source: 《桩功与四形》.

Si Xing — Vier Formen 四形Founder’s formsSi Xing — The Four Forms

The four fighting forms from Wang’s work 《桩功与四形》: 挥浪 (bailing waves) · 游龙 (swimming dragon) · 白鹤 (white crane) · 惊蛇 (startled snake). They discharge the inner force outward (内劲→外力); 挥浪 corresponds to 神龟出水 (the turtle rising from the water), and three fists and one kick come from 白鹤. Taxonomy of force: 宇宙争力 / 浑元争力 / 呼吸弹力.

Song-JinThe Song–Jin Dialectic 松紧Principle

The balance of tension and relaxation: neither slack (Song Ruan → no qi, wear on the joints) nor rigid (Jiang Si → blockages, high blood pressure). The resolution: “relaxed but not slack; firm but not stiff” — the bones firm (bearing the load), the muscles relaxed (“hanging like flowing water”). The alternation 松紧转换 is the third training principle of Shili.

T – Z

Taiji 太极Philosophy · Background

Taiji (太极, “supreme principle / primal ground”) is the cosmological starting point out of which the world unfolds into yin and yang: 无极 (emptiness) → 太极 → 阴阳 → 万物 (the ten thousand things). ⚠️ Three things not to confuse: Taiji (太极, the philosophy) · Taijitu (太极图, the symbol ☯) · Taijiquan (太极拳, the martial art). For Yiquan, Taiji is background, not doctrine — and explicitly no lineage connection: Yiquan comes from Xingyiquan, not from Taijiquan. What is shared is only the Daoist yin/yang dialectic behind the principle of contending force: Hun Yuan Li is structurally a “taiji of forces” — six opposed directions, simultaneously in harmonious balance (the “taut ball”). The demystifying line keeps the dialectic and discards the cosmological elevation.

Taijiquan 太极拳Internal martial art · Sister art

Taijiquan (太极拳, “fist art of the supreme principle”, also Tai Chi) is the best known of the three internal martial arts — alongside Xingyiquan and Baguazhang. For Yiquan it is the sister art: the same Neijia ground, the opposite method — a comparison, not a lineage (Yiquan comes from Xingyiquan, not from Taijiquan). Shared: Yang Chengfu’s basic principle 意 rather than 力 is word for word the Yiquan thesis (Yi); to which add softness (Song-Jin, Fang Song), Zhan Zhuang, Tuishou, the peng force (Peng Jin) and the silk exercise Chan Si Jin. Separate — and here is the real dividing line: Taijiquan centres on fixed forms (taolu), weapon routines and the symbolism of qi and yin-yang (太极图 ☯) — precisely what Wang discards (demystification). The line of names 心意拳 → 形意拳 → 意拳 strikes out, with “意拳”, exactly the form (形) that Taijiquan keeps at its centre. ⚠️ Not to be confused with the philosophy Taiji (太极).

Taikiken 太气拳Yiquan offshoot · Japan

Taikiken (太气拳, in full Taiki Shisei Kenpō, “fist way of the great energy”) is the Japanese line of Yiquan, founded by Kenichi Sawai (1903–1988), Wang’s only foreign student. Sawai studied in China with Wang Xiangzhai (training largely under Yao Zongxun) and, after returning to Japan in 1947, founded Taikiken — his first students at the Meiji shrine. Like Yiquan it is formless and founded on Zhan Zhuang (Japanese 立禅 ritsuzen, “standing zen”), together with free kumite (sparring). Through Sawai’s circle, impulses flowed into Kyokushin karate (Mas Oyama); it was carried on by Kubo Isato (Japan) and Jan Kallenbach (Europe). A documented exchange with the Zongxun main lineage took place in 1997.

Ting Jin 听劲Skill

“Listening to force” — the highly sensitive tactile ability to “read” the direction and quality of an opponent’s force through contact. It is sharpened by years of Mo Jin (micro-movement, myofascial activation) and applied in Tuishou.

Tuishou 推手Method · Stage 6

“Pushing hands” — the partner exercise: sensing the opponent’s force through contact and controlling him; “the jewel of Yiquan, the key to victory”.

Autonomic Nervous SystemPhysiology · Background

The autonomic nervous system regulates heartbeat, breathing, digestion and vascular width without conscious involvement. It has two poles: the sympathetic (“ergotropic”, readiness to perform, for fight or flight) and the parasympathetic (“trophotropic”, recovery and building up) — opposites that, according to the textbooks, act “complementarily (synergistically)” and can regulate finely for exactly that reason. No primary Yiquan text knows these terms; they come from modern explanatory models brought to bear on classical practice. The point of contact is precise: the sympathetic system explicitly raises “perfusion and tone of the cardiac and skeletal musculature” — which makes Song not merely an instruction about posture but one about regulation. What is decisive, though, is the direction: the parasympathetic system innervates no skeletal muscle. Muscular relaxation therefore does not come about because a “relaxation nerve” loosens the muscle, but because the sympathetic tone falls away. The same pattern holds for the breath: inhalation does not excite the sympathetic system but inhibits the vagal brake, whereupon the pulse rises (respiratory sinus arrhythmia) — and falls again on exhalation, which gives the relaxation on the out-breath its physiological counterpart. Twice over, independently: in the autonomic system the change happens by taking away, not by switching on — the physiological counterpart of what Yiquan says through Song and Yi: not to do more, but to disturb less.

The Four Diamond Warriors 四大金刚History · People

“Four great vajra” (sì dà jīngāng, after the Buddhist temple guardians) — the byname of Wang Xiangzhai’s four elite students from the Shanghai period (from about 1928): Zhao Daoxin, Han Xingqiao, Zhang Changxin and Gao Zhendong. They were the public proof in combat of the young Yiquan, and among other things systematised the Zhan Zhuang methods of various schools. Only two of them received a Dao honorific name in 1941: Zhao (道新) and Han (道宽). Yao Zongxun was not among them — he came to Wang only in 1937. Three independent sources name the same four consistently.

Western Boxing 西洋拳击Influence · History

Western boxing (西洋拳击) was for Yiquan a touchstone and a supplier of methods — not a lineage but selective appropriation in two waves. Wang’s generation (1920s–30s): in 1928 Zhao Daoxin defeated the Norwegian boxer Anderson (proof in combat); after a comparative bout (with Yu Bolu) Wang Xiangzhai introduced a boxing-like fist and guard structure, and live boxing sparring confirmed his criticism of the “fetter of forms” (demystification). Yao Zongxun (from the 1930s–40s) as the main driver: “Chinese plus Western boxing” as one of the three connections — gloves, heavy bag, focus mitts and sparring; the four Sanshou fist types outwardly resemble boxing, and the fighting frame 基本肩架 resembles a boxer’s guard. The limit — what stayed Yiquan: force from Hun Yuan Li, not from isolated arm strength; “guard = attack” (打即顾，顾即打) instead of boxing’s separation of attack and defence — “like boxing, but not really boxing” (Yao).

Wuxing 五行Philosophy · Background

Wuxing (五行, “five phases of change”: wood, fire, earth, metal, water) — a better rendering than “five elements”, since what is meant are processes and qualities, not substances. At its heart lie two chains of effect: 相生 (generation, “mother and son”) and 相克 (overcoming, “grandfather and grandson”), traditionally read in the martial arts as tactics (fist A “overcomes” B as metal overcomes wood). They are the cosmological frame of Xingyiquan, which assigns an elemental fist to each phase (五行拳: 劈崩钻炮横). Wang Xiangzhai keeps the five qualities of force but discards the 生克 cosmology as “absurd” — his formula: 只讲力，不讲五行 (“speak only of force, not of the five phases”); the nine fist types partly carry Xingyi names but are 名同实异 (“same name, different thing”). In Yiquan, Wuxing is therefore relevant above all as the thing it defines itself against (→ demystification).

Xiang Long Zhuang 降龙桩Posture

“Taming the dragon” — the combat posture that breaks the rule: alone among the Ji Ji Zhuang it carries the weight forward (70 %) instead of back. A very long stance (about 80–100 cm), the front knee strongly bent, the rear leg almost straight, the trunk inclined forward and twisted, the gaze back towards the rear hand. Sense and purpose on four levels: (1) to hold the whole-body force even in a position unfavourable for fighting — “in any fight, use the body as a whole, whatever the position” (Yao Chengguang); (2) as a touchstone: the reversed weight distribution takes from Hun Yuan Li its accustomed rear-leg support and tests whether the force depends on the principle or merely on ingrained mechanics; (3) in fighting, application above all to throws (摔法) — the rear hand at the “dragon’s tail”, the front hand at the “dragon’s neck” (Bo Jiacong); (4) performed higher and more gently, self-traction for the back (养生) — a case of Ji Yang Yi Ti within a single posture. Its counterpart is Fu Hu Zhuang (伏虎桩, “subduing the tiger”), which keeps the system standard of 70 % on the rear leg; the Buddhist formula 降龙伏虎 names the two together. It comes from traditional Chinese wrestling, with the imagery transmitted from Shaolin wall paintings; already in 1928 Wang Xiangzhai lists it among the stances that are subsumed into Hunyuan Zhuang. The common rendering “descending dragon” reads 降 as jiàng (“to descend”) — but the consistent romanisation “Xiang” attests xiáng, “to subdue”.

Xingyiquan 形意拳Internal martial art · Root

Xingyiquan (形意拳, “form-intention fist”) is the internal martial art out of which Yiquan came — the root, not merely a neighbour. It fights in straight lines and explosively, attacking directly rather than evading: the counter-design to the circling Baguazhang. Legend traces the style to General Yue Fei and his spear fighting; historically it becomes traceable some 500 years later with Ji Jike, from whose students the three schools of Shanxi, Hebei and Henan arose — the Yiquan line stands in the Hebei school. Its core includes the basic stance San Ti Shi, the Six Harmonies, the five elemental fists (splitting, crushing, drilling, cannon, crosswise) and the twelve animal forms — where explicitly what counts is not outward imitation but that “the inner character of the animal enters into the movement”. Relation to Yiquan: Wang Xiangzhai learnt Xingyiquan from Guo Yunshen. Out of standing practice in its principles of force he developed Yiquan: he kept the standing and the logic of force but discarded forms, fixed positions and the five-phase cosmology — 只讲力，不讲五行 (speak only of force, not of the five phases of change, demystification). The approach of the animal forms already points ahead: it is not the shape that carries the movement but the intent. ⚠️ Not to be confused with Xinyiquan (心意拳), its own predecessor art: one letter apart in the name, one character in Chinese — there it is 心 “heart”, here 形 “form”.

Xinyiquan 心意拳Internal martial art · Predecessor

Xinyiquan (心意拳, “heart-intention fist”), in full 心意六合拳, is the predecessor art of Xingyiquan — and thus the grandmother of Yiquan. The difference lies in the first character: 心 “heart” instead of 形 “form”. This was already the name of Ji Jike’s art; the Dai family passed their 戴氏心意拳 on traditionally within the family only — Li Luoneng was the sole exception, and out of what he learnt there he shaped Xingyiquan. Relation to Yiquan — the line of names: read the three names in sequence and a movement becomes visible. 心意拳 = heart + intent. 形意拳 = form + intent. 意拳 = intent alone. The one constant is 意 (intent). With his name, then, Wang Xiangzhai strikes out precisely what the art had gained in the meantime — the form — and leaves the core standing: not a break with tradition but its final act of subtraction. (One reading of the three attested names; that Wang himself argued this way is not recorded.) One concrete trace leads straight into Yiquan: from the Xinyi master Huang Muqiao, Wang learnt the “health dance” that became Jian Wu.

Yang Sheng Zhuang 养生桩Category

The health standing postures (as against Ji Ji Zhuang) — health cultivation and self-cultivation; in standing, sitting and lying positions. Sitting and lying are more than a substitute here: they spare knees and legs and remain possible where standing no longer is — for pronounced debility or in late pregnancy the contraindications name them explicitly as the alternative, and lying reaches those whom sitting no longer reaches. “Yiquan is a kind of medical exercise”: practised correctly, these postures overcome many illnesses and strengthen the nervous system. Wang always taught them first.

Yi 意Core principle

“Intent” — the core principle that gives the art its name: true force comes from mental focus, not from muscular training. The conscious direction of the imagination governs qi, inner strength and the alignment of the body; physical actions become the expression of mental will. It runs through every stage of training.

Yi Nian 意念Principle

“Mental intent” — the active, directed force of mind; more precise than the general Yi: “it is the Yi that creates the ‘form of the formless’.” It is the fastest force (faster than the roughly 0.2-second muscular response); it needs Fang Song in order to flow freely. Wang’s metaphor: the body “sits on the chair of the Yi Nian”. The parable of water in a bowl: movement arises from the centre outwards.

Yin and Yang 阴阳Philosophy · Background

Yin (阴, “the shady side”) and Yang (阳, “the sunny side”) are the classical pair of complementary opposites: polar opposites, each conditioning the other and together forming a whole — the fine dialectical structure of Taiji, from which the two poles (两仪) emerge. For Yiquan, yin and yang are background, not doctrine, but the most direct model of its mechanics: the whole practice lives on simultaneously acting opposites (争力) and their alternation (松紧). Instead of metaphysics, concrete pairs in the body: 松/紧 (tension and relaxation), 动/静 (movement and stillness in Zhan Zhuang), 虚/实 (empty and full), 蓄/发 (gathering and discharging in Fa Li). The balance of these opposites is Hun Yuan Li. As early as 1939 Wang Xiangzhai uses qian and kun (yang and yin), but reads them as one contending force (→ demystification).

Yiquan 意拳System

“Intention boxing” — the martial art founded by Wang Xiangzhai in the mid-1920s: work with the intent instead of fixed forms, force from the coordination of mind and body. Two aims (health and combat), eight stages of training, carried by relaxation, the Yi, breathing and the stances. → Introduction.

Yiquan Gongfa — 31 Formen 意拳功法Practice seriesYiquan Gongfa — 31 Forms

Wang Yufang’s series of 31 practices covering standing, sitting and lying (站坐卧) — a synthesis of Yangsheng Zhuang, Ji Ji Zhuang and Shili. It contains 三夹两顶 as well as the inner and outer three harmonies, and confirms the 站坐躺 principle from a primary source within the family.

Zhan Zhuang 站桩Method · Stage 1

“Standing like a tree / post standing” — the fundamental exercise and the basis of the whole method: remaining relatively still in a posture with the attention on body and mind; inner movement despite outward stillness. The rooting maximises the usable ground reaction force from which every later issuing of force draws.

Zheng Jin / Zhuo Li 争劲 / 拙力Types of force

A contrasting pair: Zheng Jin — the elastic, “contradictory” force arising from the coordinated mutual tension of all bones and muscles, governed by the nervous system (the “Jin” in Mo Jin). Zhuo Li — the “clumsy”, raw force of muscular contraction, which Yiquan sets out precisely to avoid.

Zheng Li 争力Principle · fundamental

Zheng Li (争力, “contending force”) is the basic mechanical principle out of which Hun Yuan Li arises: simultaneously acting, mutually opposed pairs of force between the parts of the body — and between body and surroundings. One pulls and presses mentally in two, later six directions at once (六面争力: up↔down · front↔back · left↔right). This pre-tension holds the body as an elastic unit — “a tyre full of high-pressure gas that answers every touch”. Wang Xiangzhai calls it the openly stated secret of the martial arts: “in movement, all the joints, large and small, always hold the two contending forces.” At the same time it is the body-mechanical version of the yin/yang dialectic — Yiquan keeps its dialectical structure but discards the mystical elevation (demystification). Two forms: the internal contending force (co-contraction of the antagonists, elastic pre-tension) and the external one against ground and surroundings (与地心争力 / 宇宙争力). Its practical training form, broken down into pairs of body parts, is the internal connections; it is built up in Zhan Zhuang and in the Song/Jin alternation, felt out in Mo Jin, and tested in movement in Shili. A related term: Zheng Jin (争劲), the elastic quality of force that results from it.

Zheng Ti He Jin 整体合劲Comparison (Taijiquan)

“Connected force of the whole body” — an expression from Chen Yu Taijiquan (not the Yiquan canon), used here for comparison: it likewise means a coordinated whole-body force (整 whole · 体 body · 合 to connect · 劲 the specific force jìn). A parallel to 全身力一 and 体整如铸.

Zheng Ti Li 整体力Force

“Whole-body unified force” (Yao lineage): force from the complete integration of the body — no part decoupled, blocked or “empty”. Related to Hun Yuan Li: Zheng Ti Li stresses the structural unity, Hun Yuan Li the availability in every direction. The metaphor: a bath with the tap running — every tension or blockage is a hole through which energy escapes. “The whole body must become a dantian.”

Zong He 综合Exercise form

“Mixed, combined” — the free combination of all the variants learnt, in any order: Zonghe Mojin (changing direction spontaneously, after about ten months), Zong He Shili (all the exercises freely chained — the most direct solo preparation for fighting and a self-test of one’s Zhan Zhuang level).

The Two KineticsModel · Yu Yong Nian

Yu Yong Nian’s physiological model: the first kinetic trains the working muscles (conventional sport), the second kinetic the resting muscles by command of the mind — and that is Zhan Zhuang. The frame explains why standing is intensive training despite its outward stillness: not less, but different. The Song/Jin terminology (relaxation and contraction of the resting muscles) describes the practice of this second kinetic precisely.
