Shuogua Commentary: Where the Eight Trigrams' Classification of All Things Comes From — Why Qian Is Heaven and Also the Horse

Shuogua (Explaining the Trigrams) is the most practical chapter in the I Ching system. It systematically explains why Qian is Heaven, the ruler, the father, and the horse; why Kun is Earth, the mother, and the ox; why Zhen is Thunder, the dragon, and the eldest son. 'Heaven and Earth are fixed in position; mountain and marsh exchange breath; thunder and wind press against each other; water and fire do not attack each other' — this is the foundational framework of trigram relationships. The animal and body-part correspondences for all eight trigrams — the source of Plum Blossom Divination's classification of things. Original text, plain English translation, and deep analysis.

Shuogua — Where the Eight Trigrams' Classification of All Things Comes From

Shuogua — Everything Around You Is Inside the Eight Trigrams

Shuogua does not talk philosophy with you. It does one very concrete thing: it assigns everything in the world to the eight trigrams. Heaven goes to Qian. Earth goes to Kun. Thunder goes to Zhen. Wind goes to Xun. Water goes to Kan. Fire goes to Li. Mountain goes to Gen. Marsh goes to Dui. With these eight major categories assigned, the subdivisions follow. Qian = Heaven = ruler = father = horse = head = metal = jade = ice = great red = fine horse = old horse = lean horse = piebald horse = tree fruit. Kun = Earth = mother = cloth = cauldron = stinginess = evenness = cow with calf = large cart = pattern = multitude = handle = black earth. Zhen = Thunder = dragon = dark-yellow = spreading = great highway = eldest son = decisive haste = green bamboo = reeds = neighing horse = galloping horse = white-blazed horse. On and on — one trigram can subdivide into a dozen or more things. What Shuogua does: it gives you a translation table. You see something in the sky — check Qian. See something on the ground — check Kun. See something in the water — Kan. See something on the mountain — Gen. This translation table later became the foundation for Plum Blossom Yi's classification of all things. Without Shuogua, there would be no Plum Blossom Yi.

Shuogua = the eight trigrams' 'dictionary of everything.' You see an ox — check Kun — ox is Kun. Your head hurts — check Qian — the head is Qian. You hear thunder — check Zhen — thunder is Zhen. Each trigram governs one category of things. Get the categories clear and you can map anything you see to a trigram. Then casting and interpreting hexagrams has a basis.

Heaven and Earth Are Fixed in Position; Mountain and Marsh Exchange Breath — The Foundational Framework of Trigram Relationships

Original text: Heaven and Earth are fixed in position. Mountain and marsh exchange breath. Thunder and wind press against each other. Water and fire do not attack each other. The eight trigrams interweave. Translation: Heaven and Earth determine the positions of above and below. Mountain and marsh have their breath flowing through each other. Thunder and wind press against each other. Water and fire do not attack each other. The eight trigrams are arranged in this interwoven pattern. Deep analysis: This is Shuogua Chapter 3 — the foundational framework of trigram relationships. Four pairs of opposites — each pair is an opposite-palace pair. Qian (Heaven) and Kun (Earth) — above and below opposites — one in the sky, one on the ground — but the relationship is 'fixed in position' — they confirm each other. Without heaven, no meaning for earth. Gen (Mountain) and Dui (Marsh) — high and low opposites — water from the mountain flows into the marsh — vapor from the marsh rises to the mountain — breath circulates — flow within opposition. Zhen (Thunder) and Xun (Wind) — movement and stillness opposites — thunder and wind often appear together — when thunder comes, wind rises — when wind comes, thunder is near — they fuel each other. Kan (Water) and Li (Fire) — nature opposites — water and fire do not mix — but 'do not attack each other' — they do not actively go after each other — each stays within its bounds. These four relationships are the skeleton of Shuogua. Once you understand these four, every classification that follows makes sense. Qian is above — so it governs everything that occupies a high position: ruler, father, head, heaven. Kun is below — so it governs everything that bears and supports: earth, mother, belly, ox. Position determines classification.

The Classification Logic of Qian — Why Qian Is Heaven, Ruler, Father, and Horse

Original text (compiled): Qian is heaven. It is round. It is the ruler. It is the father. It is jade. It is metal. It is cold. It is ice. It is great red. It is a fine horse. It is an old horse. It is a lean horse. It is a piebald horse. It is tree fruit. Translation: Qian is Heaven. It is round. It is the ruler. It is the father. It is jade. It is metal. It is cold. It is ice. It is great red. It is a fine horse. It is an old horse. It is a lean horse. It is a piebald horse. It is a fruit on a tree. Deep analysis: Every classification of Qian revolves around a single core: firm, strong, above, hard, pure. Heaven is at the very top. The ruler is at the top of a state. The father is at the top of a family. The head is at the top of a body. The logic is clear. Why the horse? Horses are the most powerful animals — they run the best — they most embody the quality of 'vigorous movement.' The fine horse is young and strong — corresponding to Qian's 'vigor.' The old horse is experienced — corresponding to Qian's 'endurance.' The lean horse is thin but powerful — corresponding to Qian's 'essence.' The piebald horse is multi-colored — corresponding to Qian's 'change.' Four kinds of horses represent four different states of Qian's vigorous movement. Tree fruit — fruit at the treetop — the highest-positioned thing — also round. You say something is round — what trigram? Qian. Because Qian is round — Heaven is round, Earth is square. Cold and ice? Qian is in the northwest — the transition between autumn and winter — cold. Great red — a flame at its highest temperature is incandescent white — white blazing into red — Qian's color. See the pattern? Nothing is random. Every item has its reason for entering the Qian trigram.

The Classification Logic of Kun — Why Kun Is Earth, Mother, Ox, and Belly

Original text (compiled): Kun is earth. It is the mother. It is cloth. It is the cauldron. It is stinginess. It is evenness. It is a cow with calf. It is a large cart. It is pattern. It is the multitude. It is the handle. In the earth it is black. Translation: Kun is Earth. It is the mother. It is fabric. It is the cauldron. It is stinginess. It is evenness. It is a cow with calf. It is a large cart. It is pattern. It is the multitude. It is the handle. In the earth, it is black. Deep analysis: Kun's core attributes: yielding, bearing, containing, broad, below. Earth bears all things — contains everything. The mother bears the family — carries everything. Cloth spreads out — wraps — contains — yielding nature. The cauldron is a pot — holds food — can cook all things — containing. Stinginess — earth's character is to store — collect in autumn, hide in winter — does not easily give out — corresponds to human stinginess. Evenness — the great earth is flat — things placed on it receive even support. Cow with calf — a mother cow nursing her calf — maternal, yielding, nurturing — the core image. Large cart — carries things — because Kun bears. Pattern — the earth's markings — mountains and rivers — natural patterns. Multitude — the earth's character is having all things upon it — hence representing the many. Handle — the grip of a vessel — you hold it and you control the vessel — the earth is the handle of all things. Everything radiates outward from 'bearing' and 'yielding' as core attributes.

Zhen, Xun, Kan, Li, Gen, Dui — A Rapid Survey of the Six Trigram Classification Logics

Zhen trigram — Thunder — shaking, rousing, erupting — hence it is the dragon (leaping upward), the eldest son (the shock of the first son's birth), the neighing horse (a call loud as thunder), the foot (the root of action). Every Zhen classification aligns with 'movement' and 'sound.' Xun trigram — Wind — penetrating, entering, pervading — hence it is the rooster (the rooster's crow spreads news like wind), the eldest daughter (wind is a gentle force), the plumb line (rope can bend and straighten — wind's formless penetration into gaps), the thigh (walking depends on the thigh — the thigh is the human 'wind wheel'). Every Xun classification aligns with 'entering' and 'following.' Kan trigram — Water — sinking, hiding, danger — hence it is the pig (pigs love mud and water), the middle son (water is the centered force), the ear (hearing dives into the interior of sound), the bow and wheel (both bow and wheel have curves — water flows downward — curved). Every Kan classification aligns with 'sinking' and 'hiding.' Li trigram — Fire — bright, attaching — hence it is the pheasant (pheasant feathers blaze like firelight), the middle daughter (fire is the bright centered force), the eye (eyes see brightness), armor (armor protects the body — hollow center — Li is hollow in the center). Every Li classification aligns with 'bright' and 'attaching.' Gen trigram — Mountain — stopping, blocking — hence it is the dog (guards the gate — prevents outsiders from entering), the youngest son (mountain is the still unmoving terminal force), the hand (hands stop things — push away, grab, steady). Every Gen classification aligns with 'stopping' and 'limiting.' Dui trigram — Marsh — joy, opening, breaking — hence it is the sheep (sheep are gentle and pleasing), the youngest daughter (marsh is the yin joyful terminal force), the mouth (speaking, opening, gap), the shaman (using the mouth to communicate with spirits). Every Dui classification aligns with 'joy' and 'mouth.'

The Body-Part Correspondences of the Eight Trigrams — Your Body Is a Small Eight-Trigram Map

Qian is the head — the head is the highest part of the body — governs everything. Kun is the belly — the belly receives and digests — bears food. Zhen is the foot — the foot is the root of action — walking depends on the feet. Xun is the thigh — the thigh is the wind wheel — the force of movement comes from here. Kan is the ear — the ear sinks inward — like a water pit — collects sound. Li is the eye — the eye is bright — seeing requires light — Li is fire. Gen is the hand — the hand stops — grabs — pushes — picks — Gen is mountain. Dui is the mouth — the mouth speaks — eats — opens and closes — Dui is marsh. Ancient people used this set of correspondences to judge health. Headache — check whether the Qian trigram is being overcome. Stomach discomfort — check the state of the Kun trigram. Foot pain — check Zhen. Ear problems — check Kan. Eye problems — check Li. Hand problems — check Gen. Throat and mouth — check Dui. Your body itself is a trigram map. You do not need to go to the hospital and get scanned to know where you feel unwell. You can first look at your 'trigram positions.' Wherever the corresponding trigram's body part sends a signal — that system is alerting you.

The Relationship Between Shuogua and Plum Blossom Yi — It Is the Origin of the Classification of All Things

That large section of 'classification of all things' in Plum Blossom Yi — Qian is Heaven, the ruler, the horse, metal and jade, the head, cold, ice — all of it comes from Shuogua. Shao Yong did not invent the classifications. He organized Shuogua's classifications into a table and added his own practice. Shuogua gives you the 'why.' Why is Qian the horse? Plum Blossom's classification of all things gives you the 'what.' What kind of horse is Qian? Fine horse, old horse, lean horse, piebald horse. Shuogua is the source. Classification of all things is the application. When you study Plum Blossom Yi — if you skip Shuogua and directly memorize the classification table — you can memorize it — but you will not be able to use it flexibly. You do not know why Qian is ice. One day you see a refrigerator and you do not know which trigram to assign it to. Understand Shuogua's logic — refrigerator → cooling → ice → Qian — and you do not need to look it up. Shuogua is the underlying code for the 'automatic classification' in your mind. The table is just a quick reference. The code is your real ability.

Have You Really Understood Shuogua?

  • When you see something, can you name which trigram it belongs to within two seconds — without flipping through a table — just using the image in your mind?
  • When one thing could cross two trigrams, can you judge by its 'primary feature' — for example, a metal plate — is it round = Qian, or hollow and able to hold things = Dui?
  • When you interpret a hexagram, are you using trigram classifications correctly? The ti trigram represents you. The yong trigram represents the other party or the external environment. Classifications must map to the right roles.

Common Breakers

  • Rote memorization of the classification table. The classification logic of Shuogua is the real focus. Why is Qian the horse? Because horses run fast — vigorous movement — the same nature as Heaven's vigorous movement. Why is Kun the ox? Because oxen are docile and can bear heavy loads — the same nature as Earth's bearing and supporting. Understand this logic and you can classify new things on your own. No memorization needed.
  • Mapping modern biological taxonomy onto the eight trigrams. The pheasant goes to Li — not because it belongs to the bird category — because its feathers are dazzling → radiance → Li is fire and brightness. The basis of classification is 'characteristic' — not 'species.' Ancient people had no biological taxonomy. They grouped by 'what hexagram does this thing resemble?'
  • Thinking Shuogua's classifications are absolute. The same thing can belong to different trigrams in different contexts. A river — from the surface shape of water → Kan. From the two banks facing each other → Li (hollow center). Shuogua gives you reference. It does not give you dogma. Shao Yong himself observed first and checked afterward — not the other way around.

Shuogua Wisdom: Classification Thinking Applied to Career, Relationships, Personality, and Health

Career & Wealth

What is your 'trigram position' at your company? The boss is Qian — at the highest point — governs everything. Your manager might be Li — shining in the middle — linking upper and lower levels. You are Zhen — moving at the base level — charging at the front line. Finance is Kan — managing water — managing the flow of money. HR is Kun — bearing — managing people. People in different trigram positions communicate in completely different ways. Qian-type boss — likes brevity — say the result directly — no preamble. Kun-type colleague — needs you to be gentle — give space — do not apply pressure. Zhen-type subordinate — give them a task — do not micromanage — they will charge on their own. Kan-type partner — cautious — give them security — do not make them feel like you are digging a trap. Shuogua's classifications are not for fortune-telling. They are for understanding people. Sort your workplace by the eight trigrams and your communication efficiency doubles.

Love & Relationship

What trigram is your partner? Qian-type partner: strong — needs face — you must give space — cannot press. Kun-type partner: accommodating — yielding — but do not think they are easy to bully — Kun's bottom line runs deep. Zhen-type partner: passionate — impulsive — comes like a flood — leaves fast too — you need emotional stability. Xun-type partner: penetrating — quiet — makes no sound — but over time you discover they are in every corner of your life. Kan-type partner: deep — does not like to talk when something is wrong — you have to guess — give them time to open up slowly. Li-type partner: passionate — needs attention — you must be a good audience — their light needs to be seen. Gen-type partner: stable — few words — dislikes change — do not rush them — give them time to digest. Dui-type partner: talkative — loves to express — you need to listen — their expression is their love. No right or wrong. Only matching. Qian meets Gen — Qian keeps wanting to push forward — Gen keeps wanting to stop and stabilize — the two cannot find the same rhythm. Shuogua is not a matching guide. But after reading it, at least you know why the rhythms do not match.

Personality

Applying Shuogua's classifications to personality works with eerie accuracy. Qian-type personality: strong goal orientation — dislikes being managed — needs to be in control. Kun-type personality: cooperative — safety-first — dislikes conflict — can carry weight. Zhen-type personality: explosive energy — acts fast — but endurance is weak — interests shift easily. Xun-type personality: penetrating — low-key — no movement on the surface — everything moving underneath — a friend of time. Kan-type personality: deep — thinks deeply — mood swings wide — needs alone time. Li-type personality: expressive — needs attention — lots of ideas — but easily distracted. Gen-type personality: conservative — dislikes change — reliable — but can be stubborn. Dui-type personality: expressive — talks a lot — highly persuasive — but can say too much and spill too much. Most people are a mix of two trigrams — Zhen + Li for example — high action drive plus strong expression — suited for entrepreneurship. Kan + Gen — deep thinking but slow action — suited for research. Take a look: which trigram are you?

Health

Your body parts correspond to the eight trigrams. Headache — Qian position — you may have had too much stress recently — Qian is the head — stress hits the head first. Stomach discomfort — Kun position — your digestive system is protesting — have you eaten too much lately — Kun's capacity for receiving has reached its limit. Foot pain — Zhen position — have you been running too much — or not moving at all for too long — Zhen needs moderate movement — no movement hurts, too much movement hurts. Ear problems — Kan position — the kidneys open into the ears — Kan corresponds to kidneys — have you been staying up too late draining kidney water. Eye discomfort — Li position — have you been staring at screens too long — Li is fire — eyes are firelight — fire too strong damages the eyes. Hand soreness — Gen position — have you been gripping too tightly lately — Gen is the hand — wanting to hold onto too many things. Sore throat — Dui position — have you been talking too much lately — or holding back words that needed to come out. Use your body as a trigram map for diagnosis. Faster than running between hospital departments. First check which trigram position is sending a signal. Adjust the corresponding lifestyle habit. Often you can bring yourself back on your own.

Practical Applications of Shuogua

  • Do a 'Trigram Classification' of Your Daily Life: Take a sheet of paper. Draw eight boxes — Qian, Dui, Li, Zhen, Xun, Kan, Gen, Kun. Write everything you see today into the eight boxes. See a car — check Zhen (movement). See a water cup — check Dui (opening). See a computer — check Li (emitting light). See a book — check Li (culture). See a door — check Gen (stopping, blocking). See a wallet — check Kun (containing). Keep this up for a week. Your trigram classifications will shift from 'memorized' to 'intuitive.' Intuition is ten times faster than memory.
  • Use the Trigram Body Correspondences for a Health Self-Check: Full body scan: head → Qian, belly → Kun, feet → Zhen, thighs → Xun, ears → Kan, eyes → Li, hands → Gen, mouth → Dui. For each body part ask yourself — has there been any discomfort here recently? If yes, write it down. See whether your recent lifestyle habits have gone off track at this trigram position. Headache — check stress. Bloating — check diet. Foot soreness — check activity level. Hand soreness — check whether you have been gripping too tightly lately — let go of one or two things at work.
  • Determine What Trigram Type the People Around You Belong To: Pick the five people you interact with most in your life. Take a slip of paper for each person. Write their name. Then write the three deepest impressions they give you. Match these three impressions to the eight core words: vigorous, yielding, moving, entering, sinking, attaching, stopping, joyful. If they match, that person belongs to that trigram. Once you know their trigram, you know how to communicate with them. Qian-type people — do not beat around the bush. Zhen-type people — give them a target. Kan-type people — give them security. Li-type people — give them attention. That simple.

Shuogua: Common Questions

Q:Aren't the classifications in Shuogua too many? How can I remember them all?

A:

You do not need to memorize all of them. Remember the eight core words — vigorous, yielding, moving, entering, sinking, attaching, stopping, joyful — that is enough. The rest — once you understand the classification logic — you can deduce on your own. Why is Qian the horse? Because horses are vigorous. Why is Kun the ox? Because oxen are yielding. Why is Zhen the dragon? Because dragons move. Why is Xun the rooster? Because roosters crow to spread news — wind enters. Every time you see a new classification, first ask yourself: what is the connection between this item and the core word? If you find the connection, you will remember it. If you cannot find the connection, this classification is outside your current understanding. Do not force-memorize it. Look it up when you need it.

Q:Can the same thing belong to multiple trigrams? How do I choose when interpreting?

A:

Yes. A river — in its water form, Kan. In its two banks facing each other, Li. A plate — in its roundness, Qian. In its concavity and ability to hold things, Dui. When interpreting, choose 'the most prominent feature in the current context.' You are focused on shape right now — use Qian. You are focused on function — use Dui. There is no absolutely correct answer. Only 'the most fitting answer in the current context.' This is the flexibility of trigram classification. It is also why rote memorization is useless. You need to understand context.

Q:How do I know which trigram personality type I am?

A:

Ask yourself one question: in your most natural state, do you charge forward (Zhen), or stay steadily in place (Gen), or wrap and contain (Kun), or keep talking (Dui), or prefer being alone thinking through things (Kan), or need to be seen by others (Li), or quietly penetrate beneath the surface (Xun), or refuse to submit to anyone, needing to be in control (Qian)? Your first response — the least filtered one — is your primary trigram. The same person may lean toward different trigrams at different life stages. At twenty you might be Zhen. At forty you might be Gen. Trigram type is not fixed. It shifts with your life phase.
