Chinese Astrology

Ba Zi, the four pillars: your birth written as year, month, day and hour, each in a stem and a branch.

Chinese astrology as it is actually practised is not the animal of your birth year. It is Ba Zi, the eight characters: four pairs of a heavenly stem and an earthly branch, one pair for the year, month, day and hour. The ten stems carry the five elements in their yin and yang forms, the twelve branches carry the animals, and the reading is about how those elements support and control one another across the chart. The day stem is you, and everything else is read in relation to it.

That is why two people born in the same animal year can be read so differently: the year is one pillar of four. The luck pillars then move the chart forward in ten year steps, which is how Ba Zi speaks about timing. The system took its present form under the Song, and it remains the working method of practitioners across Chinese speaking Asia.

How it is computed

Luck pillar direction depends on birth sex, which you have not given. Both directions are shown; the one that matches you is yours.

The twelve animals

The twelve branches wear animal faces; this is the one your year, month, day or hour carries.

Rat

The Rat is the quick mind of the zodiac. You notice what others miss: the opening, the shortcut, the shift in the room. Resourceful and sociable, you thrive where wit matters more than force. Your instinct is to gather: ideas, allies, reserves for winter. Trust that cleverness, but let it serve connection, not just survival.

Ox

The Ox is patient strength. You carry weight without complaint and finish what others abandon. Your word, once given, holds. The world may move faster than you, but it rarely moves further: steadiness is your quiet advantage. Guard against stubbornness hardening into isolation; the field is plowed best when you let others walk beside you.

Tiger

The Tiger is courage that acts. You feel injustice in your body and move before the cautious have finished deliberating. Magnetic, independent, born to lead from the front: your presence changes a room. The lesson of the Tiger is timing: the pounce lands because of the stillness before it. Learn to wait without losing your fire.

Rabbit

The Rabbit is grace under watchfulness. You read moods the way others read weather, and you build beauty and peace wherever you settle. Diplomatic, refined, quietly discerning, you win by never forcing the door. Your caution is wisdom, not weakness; just remember that some things you long for stand on the far side of a risk.

Dragon

The Dragon is the only creature of the zodiac born from imagination, and you carry that inheritance: vision larger than circumstance. Confident, vital, drawn to what has never been done, you lift others simply by believing out loud. Your storms are real: pride, impatience. But so is the rain they bring. Dream in public; it is your gift.

Snake

The Snake is depth that does not announce itself. You sense the current beneath the conversation and rarely mistake noise for truth. Elegant, private, instinctively strategic, you shed old skins whole rather than change by halves. Others may call you mysterious; you are simply unwilling to speak before you understand. Trust that inner knowing. It is seldom wrong.

Horse

The Horse is motion with a heart. You need open ground in work, in love, in thought, and you give warmth generously as long as no one grips the reins too tightly. Energetic, candid, quick to inspire, you remind others what freedom feels like. Your task is endurance: learn to run long, not only fast.

Goat

The Goat is gentleness with sure footing. You climb terrain others call impossible, quietly and at your own angle. Artistic, kind, deeply attuned to comfort and beauty, you make harsh places habitable for everyone near you. Your softness is not fragility: it is how you hold steep ground. Ask for what you need; the herd wants to give it.

Monkey

The Monkey is intelligence at play. You solve by experimenting, charm by improvising, and treat every locked door as a puzzle rather than a verdict. Versatile, curious, mischievous in the best sense, you keep the world from taking itself too seriously. Your challenge is follow-through: the trick delights, but mastery asks you to stay in the tree.

Rooster

The Rooster is clarity spoken aloud. You see the flaw in the plan, the loose thread, the hour of dawn, and you say so, whether or not the barnyard is ready to hear it. Precise, observant, proud of honest work, you keep standards alive when others let them slide. Temper the critique with warmth, and your voice becomes indispensable.

Dog

The Dog is loyalty with a conscience. You defend your people without being asked and smell dishonesty long before it shows itself. Fair-minded, sincere, anxious mostly on behalf of others, you are the friend everyone means when they say the word. Let yourself receive the devotion you give: vigilance rests best in company it trusts.

Pig

The Pig closes the zodiac with abundance and good faith. You believe in people, share what you have, and find genuine pleasure in the ordinary feast of living. Honest, tolerant, harder-working than your ease suggests, you draw good fortune by expecting it of others. Guard your generosity from those who mistake it for naivety: it is actually strength.

The five elements

Wood, fire, earth, metal, water: the five phases that feed and check one another.

Wood

Wood is the element of growth: the green force that splits pavement and reaches for light. In you it appears as vision, planning, the urge to begin and to expand. Wood people are the spring of any endeavor: generous, upward-reaching, sometimes overextended. Your health lies in flexibility; the tree that bends outlives the storm.

Fire

Fire is the element of transformation and reach: warmth that gathers people, light that makes things visible. In you it appears as passion, expressiveness, the power to inspire and to burn through obstacles. Fire people are the summer of life: radiant, quick, sometimes consuming. Tend your flame deliberately; fire that is fed lasts, fire that only blazes dies young.

Earth

Earth is the element of stability and nourishment: the ground every other element stands on. In you it appears as reliability, practical care, the ability to hold a center while seasons turn. Earth people are the harvest keepers: trustworthy, deliberate, sometimes slow to change. Your gift is making others feel held. Remember to let the field rest, too.

Metal

Metal is the element of refinement: ore pressed into blade, blade honed into edge. In you it appears as discipline, discernment, the courage to cut away what no longer serves. Metal people are the autumn of the cycle: principled, precise, drawn to essence over ornament. Your strength is knowing what to keep. Let grief pass through you; it sharpens into clarity.

Water

Water is the element of depth and adaptation: it takes the shape of any vessel yet wears down stone. In you it appears as wisdom, intuition, the long memory that connects what others see as separate. Water people are the winter of the cycle: reflective, resourceful, quietly persistent. Fear is your element's shadow; movement is its cure. Keep flowing.

The ten heavenly stems

The ten heavenly stems, each an element in its yin or yang form. Your day stem is you.

Jia

Jia is yang wood: the tall tree that grows straight toward the sky. Where Jia appears in your chart, you meet your pioneering nature: upright, principled, first to break ground and slow to bend. Like the great tree, you shelter others and hold your position through storms. Your risk is rigidity; even oaks must sway to stand.

Yi

Yi is yin wood: the vine, the grass, the flower that bends with wind and climbs whatever stands nearby. Where Yi appears in your chart, you meet your adaptable nature: graceful, persuasive, growing around obstacles rather than through them. What looks delicate is quietly unstoppable; grass returns after every fire. Flexibility is your form of strength.

Bing

Bing is yang fire: the sun's blaze, generous and impossible to ignore. Where Bing appears in your chart, you meet your radiant nature: warm to everyone, openhanded, lifting moods simply by arriving. Like the sun, you give without keeping accounts, and you need sky to shine in. Beware of burning for audiences that give no warmth back.

Ding

Ding is yin fire: the lamp flame, the candle in the window, the hearth. Where Ding appears in your chart, you meet your illuminating nature: warmth that works close, insight that finds exactly what was hidden in the dark. You do not light the whole world; you light the next step, for one person at a time. That is enough. It always was.

Wu

Wu is yang earth: the mountain, massive and unmoved. Where Wu appears in your chart, you meet your steadfast nature: dependable, protective, the fixed point others navigate by. Storms cross the mountain; the mountain remains. Your gift is holding ground when everything shakes. Your work is remembering that even mountains are shaped, slowly, by what they allow to touch them.

Ji

Ji is yin earth: the garden soil, tilled and fertile. Where Ji appears in your chart, you meet your cultivating nature: patient, receptive, able to take whatever is planted in you and return it multiplied. People grow in your company and often cannot say why. That is Ji's quiet art. Tend your own ground as faithfully as you tend everyone else's.

Geng

Geng is yang metal: raw ore and the forged axe, strength that has passed through fire. Where Geng appears in your chart, you meet your decisive nature: dutiful, direct, built for hard tasks others avoid. You cut cleanly: through confusion, through excuses, through what must end. Justice matters to you more than comfort. Let the blade rest sometimes; edges kept too busy grow dull.

Xin

Xin is yin metal: gold worked into jewelry, the needle, the fine blade. Where Xin appears in your chart, you meet your refined nature: precise, discerning, sensitive to quality in things and in people. You were not made rough on purpose; you were polished by pressure into something that catches light. Value that finish, and do not apologize for high standards.

Ren

Ren is yang water: the ocean, the great river in flood. Where Ren appears in your chart, you meet your expansive nature: resourceful, ambitious, carrying many currents at once toward a distant sea. You absorb knowledge and people the way rivers absorb rain, and you rarely reveal your full depth. Channel that power; water without banks is not freedom but flood.

Gui

Gui is yin water: rain, dew, morning mist, water in its subtlest form. Where Gui appears in your chart, you meet your intuitive nature: imaginative, gentle, able to seep into places force could never enter. You nourish invisibly; by the time others notice your influence, the garden has already grown. Trust impressions that arrive without explanation. They are your native language.

The twelve earthly branches

The twelve earthly branches, which carry the animals and the hidden stems inside them.

Zi

Zi is the first Earthly Branch: the Rat's hour, deep midnight from eleven to one, the winter solstice of the daily round. It belongs to water, the seed of yang stirring inside greatest darkness. Where Zi appears in your pillars, something in you begins quietly: instinct, cleverness, new life gathering strength before anyone knows it exists.

Chou

Chou is the second Earthly Branch: the Ox's hour, one to three in the morning, deep winter earth. It is the time of hidden labor, frost working the soil while the world sleeps. Where Chou appears in your pillars, you carry quiet endurance: the patience to prepare in darkness for a spring no one else yet believes in.

Yin

Yin is the third Earthly Branch: the Tiger's hour, three to five in the morning, and the first month of spring. It belongs to wood, the moment life bursts from dormancy, bold and sudden. Where this branch appears in your pillars, you hold the energy of beginnings: raw courage, early rising, the nerve to act while others still sleep.

Mao

Mao is the fourth Earthly Branch: the Rabbit's hour, five to seven, dawn itself, and the full bloom of spring. It belongs to wood at its most tender and green. Where Mao appears in your pillars, you carry dawn's qualities: gentleness that wakes the world without startling it, growth that happens gracefully, beauty as a daily practice rather than an occasion.

Chen

Chen is the fifth Earthly Branch: the Dragon's hour, seven to nine in the morning, when mist lifts and the day commits itself. It belongs to earth that stores spring's water. Where Chen appears in your pillars, you hold transformative reserves: ambitions larger than they first appear, and the capacity to summon rain when the moment finally calls for it.

Si

Si is the sixth Earthly Branch: the Snake's hour, nine to eleven in the morning, when the sun climbs toward its height and summer begins. It belongs to fire in its rising form. Where Si appears in your pillars, you carry concentrated intensity: intelligence that warms slowly, then holds its heat, and a knack for arriving at power without commotion.

Wu

Wu is the seventh Earthly Branch: the Horse's hour, eleven to one, high noon, midsummer, yang at its absolute peak. It belongs to fire. Where Wu appears in your pillars, you carry full daylight: visibility, vitality, the courage to be seen entirely. Remember what noon teaches: the brightest hour is also the turning point toward rest.

Wei

Wei is the eighth Earthly Branch: the Goat's hour, one to three in the afternoon, late summer warmth. It belongs to earth that holds the day's accumulated heat. Where Wei appears in your pillars, you carry the afternoon's gifts: nourishment, hospitality, the sweetness of work already half done, and a talent for making rest feel earned and shared.

Shen

Shen is the ninth Earthly Branch: the Monkey's hour, three to five in the afternoon, when the day's momentum turns clever and quick. It belongs to metal in its raw, active form. Where Shen appears in your pillars, you carry ingenuity under pressure: the mind that improvises tools, finds the workaround, and does its best thinking while in motion.

You

You is the tenth Earthly Branch: the Rooster's hour, five to seven in the evening, sunset, and the heart of autumn. It belongs to metal, refined and finished. Where You appears in your pillars, you carry the harvest's discernment: the eye that judges what the day was worth, keeps what ripened, and says plainly what must be said before dark.

Xu

Xu is the eleventh Earthly Branch: the Dog's hour, seven to nine at night, when doors are barred and lamps are lit. It belongs to earth that stores autumn's fire. Where Xu appears in your pillars, you carry the watchman's virtues: loyalty after dark, protection of what the day gathered, and faith kept precisely when no one is checking.

Hai

Hai is the twelfth and final Earthly Branch: the Pig's hour, nine to eleven at night, early winter, the cycle's gentle close. It belongs to water, flowing home to the sea. Where Hai appears in your pillars, you carry the wisdom of endings: gratitude, release, honest rest, and the deep waters where the next cycle is already dreaming itself.

Yin and yang

Yin and yang, the two halves every stem and branch belongs to.

Yin

Yin is the receptive half of every whole: night, valley, stillness, the moon, the listening ear. It is not passivity but a different kind of power: the power that conserves, deepens, and completes. Where yin marks your chart, you work by attraction rather than pursuit, by understanding rather than force. The valley outlasts the storm that thunders over it.

Yang

Yang is the active half of every whole: day, summit, motion, the sun, the voice that speaks first. It initiates, expands, and makes visible. Where yang marks your chart, you work by doing: momentum comes naturally, and waiting costs you effort. Remember that yang exhausts itself without yin to return to; even the sun sets in order to rise.

The day master

The stem of your day pillar: the self the whole chart is read in relation to.

Your day master is the heavenly stem of your day pillar, and it is you. Of the eight characters, this one alone is not a circumstance but the self standing in the middle of them, which is why the whole chart is read from here: every other stem and branch is named by what it does to this one, whether it feeds you, drains you, controls you, or competes with you. Its element and polarity set your basic nature, and its strength, judged against the season you were born into, decides what the rest of the chart means. Two people can hold nearly identical characters and read as opposites, because the day master they are measured against differs.

Hidden stems

Each branch holds stems inside it, which is where a reading finds what is not on the surface.

Every earthly branch conceals one to three heavenly stems, called its hidden stems, and they are the reason a branch is never quite the single element it appears to be. A branch is a span of time rather than a thing, so alongside its own element it can carry a second one it holds in reserve and a third left over from the season just past: principal qi, middle qi, and residual qi, in that order of weight. A reading counts them because most of a chart is not on the surface. Elements you seem to lack and ten gods that appear nowhere in the visible stems are often sitting inside your branches, doing quiet work.

The ten gods

How each element in the chart relates to your day master: friend, rival, output, wealth, authority, resource.

Bi Jian

Friend is a stem of your own element at your own polarity: the chart's word for someone standing exactly where you stand. It reads outwardly as siblings, peers, and rivals of equal footing, and inwardly as self-reliance and plain willpower. A chart heavy in Friend gives a person who is hard to command and slow to defer, and who finds resources divided rather than gathered, because an equal in the room has a claim on them too. Where your day master is weak, though, this is the very support that carries you.

Jie Cai

Rob Wealth is your element again, at the opposite polarity, and the name is literal: it takes the wealth your day master was reaching for. It reads as competitors, siblings who want the same thing, and partners with an agenda of their own, and in you as nerve, appetite for risk, and a generosity that does not always count the cost. A chart heavy in Rob Wealth tends to make money move in currents rather than settle, and it pushes you into ventures shared with people whose interests are not quite yours. Keep your own hand on your own affairs; that is this god's whole lesson.

Shi Shen

Eating God is what your day master produces at the same polarity: output that flows out easily and returns as pleasure. It governs appetite in every sense, food, art, craft, humor, and in a woman's chart it is a child star, read specifically as daughters. It is also the god that tames Seven Killings, turning raw pressure into something actually made. A chart full of Eating God is easygoing and quietly productive, talented without needing to prove it, and fond of comfort. Its risk is not conflict but complacency, and a steady drain on a day master that may not have the strength to spare.

Shang Guan

Hurting Officer is output at the opposite polarity, and its name says exactly what it does: it strikes at Direct Officer, the god of rank and rules. It is the brilliant, unruly voice, quick and critical, gifted at performance, argument, and invention, and impatient with anyone who outranks it on paper. A chart heavy in Hurting Officer produces real talent alongside real friction: bosses resented, conventions broken, and, in the classical texts, strain on a woman's marriage, since Officer stood for the husband in the world those texts were written in. That reading is the tradition's, not a forecast about yours. Used well this is originality. Used carelessly it is a burnt bridge.

Pian Cai

Indirect Wealth is what your day master controls, at the same polarity: wealth that moves. It is the money of deals, ventures, commissions, and windfalls rather than salary, and traditionally it stands for the father, and for a lover in a man's chart. A chart heavy in Indirect Wealth gives a sociable, open-handed person who sees an opportunity before others do and earns in waves rather than in a steady line. What it asks is that you build a floor under the waves, because this god is far better at making money than at keeping it.

Zheng Cai

Direct Wealth is what your day master controls at the opposite polarity: wealth you earn and hold. It is salary, property, the asset registered in your name, the return that comes from work rather than from a bet, and in a man's chart it stands for the wife. A chart heavy in Direct Wealth gives a practical, thrifty, dependable person who prefers a smaller certain sum to a larger uncertain one and builds security by accumulation. Its failure is not recklessness but tightness: guarding so carefully that nothing is ever risked, and so nothing grows.

Qi Sha

Seven Killings is the element that controls your day master at the same polarity: authority without courtesy, pressure with nothing to soften it. Also called Indirect Officer, and named for its position seven stems along the cycle, it reads as rivals, hard circumstances, danger, and the drive that answers them. A chart heavy in Seven Killings gives someone decisive and competitive who works well under conditions that would flatten other people, and it can equally grind that person down; a strong day master, or the taming influence of Eating God or Resource, decides which. Governed, this is the general's star.

Zheng Guan

Direct Officer is the element that controls your day master at the opposite polarity: authority that arrives with protocol. It is rank, title, the rule you agreed to, the reputation you now have to keep, and in a woman's chart it stands for the husband. A chart heavy in Direct Officer produces a conscientious, principled person who does things properly and does well inside institutions, where the ladder is visible and the standards are written down. Too much of it, though, is a life run by other people's expectations, until duty and the fear of stepping out of line become impossible to tell apart.

Pian Yin

Indirect Resource is the element that produces your day master at the same polarity: support that arrives sideways. Older texts also call it the Owl, and it stands for unconventional learning, intuition, specialized or esoteric knowledge, and the caretaker who was not your mother. It sits badly with Eating God, whose plate it is said to steal, so it tends to sharpen the mind while thinning the enjoyment. A chart heavy in Indirect Resource is quick, private, skeptical, and expert in something few people nearby understand, and it can overthink itself out of acting at all.

Zheng Yin

Direct Resource is the element that produces your day master at the opposite polarity: support in its plainest form. It reads as the mother, and as education, credentials, mentors, protection, and anything that feeds you without asking payment first. A chart heavy in Direct Resource gives a well-taught, well-cushioned, morally serious person whom others instinctively look after. Its cost is momentum: resource suppresses output, so someone this protected can spend years preparing for work they never quite begin.
