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.
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 branches wear animal faces; this is the one your year, month, day or hour carries.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Wood, fire, earth, metal, water: the five phases that feed and check one another.
Wood is the green force that splits pavement reaching for light. In you it shows up as vision, planning, the urge to begin and to widen. Wood people are the spring of any undertaking, generous and upward and sometimes overextended. Health here is flexibility. The tree that bends outlives the storm.
Fire gathers people and makes things visible. In you it shows up as passion, expressiveness, the power to inspire and to burn straight through an obstacle. Fire people are the summer of a life: radiant, quick, and sometimes consuming. Tend the flame deliberately. Fire that is fed lasts; fire that only blazes dies young.
Earth is the element that holds. Stability, nourishment, the ground that takes weight without complaint. In you it shows up as reliability, patience, the instinct to feed and to steady other people. Earth people are the late summer, the harvest. The risk is holding so much for others that nothing is left to hold you.
Metal cuts and refines. In you it shows up as clarity, standards, the ability to say what a thing is and what it is not. Metal people are the autumn: precise, principled, unwilling to keep what does not earn its place. Kept too sharp, the same quality turns rigid, and a blade with nothing to cut turns on its owner.
Water finds the way. In you it shows up as depth, adaptability, the intelligence that goes around rather than through. Water people are the winter of the cycle: reflective, patient, holding more than they show. Still water grows stagnant and moving water carves canyons, and the difference is whether it is going somewhere.
The ten heavenly stems, each an element in its yin or yang form. Your day stem is you.
Jia is yang wood, the tall tree that grows straight up. Upright, principled, first to break ground and slow to bend: that is the Jia character wherever it falls in a chart. Like the great tree you shelter others and hold position through storms. The risk is rigidity. Even oaks have to sway to stand.
Yi is yin wood: the vine, the grass, the flower that bends with the wind and climbs whatever stands nearby. Where it falls, you adapt rather than insist, growing around an obstacle instead of through it. What looks delicate here is quietly unstoppable, because grass comes back after every fire. Flexibility is the form your strength takes.
Bing is yang fire, the sun's blaze, generous and impossible to ignore. It brings warmth to everyone, an open hand, and moods that lift simply because you arrived. Like the sun you give without keeping accounts, and you need sky to shine in. Watch for burning on behalf of audiences that give no warmth back.
Ding is yin fire: the lamp flame, the candle in the window, the hearth. It does not flood a room, it shows one person the way. Where Ding falls you illuminate at close range, patient and particular, warming what is near rather than proving anything to the dark. A small flame needs tending, and goes out when nobody tends it.
Wu is yang earth, the mountain, massive and unmoved. Dependable, protective, the one others build against when the weather turns. A mountain gives shelter and asks nothing, and it also does not move when moving is what the moment needs. Stillness here is a gift until it becomes the only answer.
Ji is yin earth: garden soil, tilled and fertile. Patient, receptive, quietly making things possible for other people to grow in. This is the least showy of the stems and the one most things depend on. Soil that is worked without rest goes thin, which is the warning it carries.
Geng is yang metal, raw ore and the forged axe, strength that has been through fire. Direct, decisive, willing to cut. Where Geng falls, you say what a thing is and act on it, and people know where they stand with you. An axe is only useful in a hand that knows what to fell.
Xin is yin metal: gold worked into jewelry, the needle, the fine blade. Precision, taste, an eye that finds the flaw and the beauty in the same glance. Where Xin falls you refine rather than force. The cost of that eye is that it turns on its owner as readily as on the work.
Ren is yang water, the ocean and the river in flood. Resourceful, wide, carrying more than it shows and going where it decides. Where Ren falls, you move by volume and persistence rather than by force. Water that wide can flood what it meant to feed.
Gui is yin water: rain, dew, morning mist, water in its subtlest form. It arrives everywhere without announcing itself, and it goes deep. Where Gui falls, you know things before you can say how, and you soak up whatever room you are in. Mist obscures as easily as it nourishes.
The twelve earthly branches, which carry the animals and the hidden stems inside them.
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. In a chart, Zi begins things quietly. Instinct, cleverness, new life gathering strength before anyone knows it exists.
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. Chou is quiet endurance in a chart: the patience to prepare in the dark for a spring nobody else believes in yet.
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. A chart with Yin in it holds the energy of beginnings. Raw courage, early rising, the nerve to act while others are still asleep.
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. Mao brings dawn's qualities to a chart. Gentleness that wakes the world without startling it, and growth that happens while nobody is watching.
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. Chen means reserves. Ambitions larger than they first appear, and the capacity to become something the earlier version could not have guessed at.
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. Si is concentrated intensity in a chart: intelligence that warms slowly and then holds its heat, and a knack for the timing of a strike.
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. Wu is full daylight in a chart. Visibility, vitality, the courage to be seen entirely, and the memory that noon is also the turn.
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. Wei carries the afternoon's gifts. Nourishment, hospitality, and the sweetness of work already half done.
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. Shen is ingenuity under pressure: the mind that improvises a tool, finds the workaround, and enjoys the problem more than the solution.
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. You brings the harvest's discernment. The eye that judges what a day was worth, keeps what ripened, and is unsentimental about the rest.
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. Xu holds the watchman's virtues. Loyalty after dark, protection of whatever the day gathered, and a wariness that is rarely wrong.
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. Hai carries the wisdom of endings: gratitude, release, honest rest, and the deep water where the next beginning is already forming.
Yin and yang, the two halves every stem and branch belongs to.
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 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 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.
How each element in the chart relates to your day master: friend, rival, output, wealth, authority, resource.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Where a stem's element stands in a branch, from growth to nurture. Yang stems run forward around the twelve and yin stems backward, so the same branch is a peak for one and a grave for its partner.
Growth (长生). The element arrives, unformed and full of promise. Whatever the pillar governs begins here, and beginnings are forgiven their clumsiness.
Bath (沐浴). The washing stage, and the unstable one: fresh, exposed, easily distracted. Traditionally read as the place where appetite outruns judgment.
Cap and Sash (冠带). Coming of age: the element is dressed for a role it has not yet held. Capable, and eager to be taken seriously.
Officer (临官). The post is taken. Strength without the exposure of the peak, which is why many readers prefer it to the peak itself.
Prosperous (帝旺). The peak. The element is at its strongest here and has nowhere further to go, which the tradition treats as a warning as much as a blessing.
Decline (衰). Just past the peak. Nothing is lost yet, but the force behind it has begun to ease.
Illness (病). The element weakens and needs help from elsewhere in the chart. What this pillar governs asks for support rather than effort.
Death (死). Quiet, not catastrophic: the element has no strength of its own here and works through others, or through thought rather than action.
Tomb (墓). The storage stage, where the element is kept rather than spent. Read as gathering, hoarding, and things that come out later.
Severance (绝). The lowest point, where the element is cut off entirely. Traditionally the turn: nothing left of the old, and the new not yet arrived.
Conception (胎). The element exists but is not yet itself. Potential held in the dark, which is why this stage reads as plans and pregnancies.
Nurture (养). Fed and waiting. The element is safe here and grows without being tested, which is a comfort and a delay at once.
Four pillars are not read one at a time. The branches combine, clash, harm and punish each other, and that is where a chart stops being a list and starts being a situation.
Six harmony (六合). Two branches that bind and cooperate, producing a third element between them. The gentlest of the combinations: partnership, and a pull toward what the pair makes together.
Three harmony (三合). Three branches four apart, which together make one element completely: its birth, its peak and its grave. The strongest constructive pattern in a chart.
Seasonal gathering (三会). Three branches of one quarter of the year, all of one element. Stronger than a trine, because it is not a combination at all but a season arriving whole.
Clash (六冲). Two branches directly opposite, whose hidden stems contradict each other. Movement, disruption and travel; what is clashed is shaken loose, for better or worse.
Harm (六害). A quieter injury than a clash: one branch spoils a harmony the other was relying on. Read as grievance, misunderstanding, and help that arrives wrong.
Punishment (三刑). Three branches, or two, that wear on each other: the ungrateful punishment, the bullying punishment and the rude one. Friction that comes from within a relationship rather than from outside it.
Self punishment (自刑). A branch repeated: Chen, Wu, You or Hai meeting itself. The tradition reads it as a person who is their own obstacle in whatever that pillar governs.
Ten stems cover only ten of the twelve branches in each decade of the sixty, so two are left empty. What an empty branch governs is present and hard to hold.
Empty (空亡). Ten stems cover only ten of the twelve branches in each decade, so two are left without a stem to pair with. What an empty branch governs is present but hard to hold: it asks for a different kind of effort, and the tradition reads it as a door to the spiritual rather than a loss.
