Wu-Yin Day Pillar: Wu Earth over Yin Wood, Spouse Palace Seven Killings
What are Wu-Yin people like? With Wu Earth as your Day Master, you are like a mountain: your very presence puts people at ease. Your day branch holds Seven Killings, so you are bold, take responsibility and do your best work under pressure. In our sample of 280 Wu-Yin charts, 22.9% are strong and 32.5% weak, so strength depends on the birth month. Below: personality first, then love and how the pillar reads for women and men.
The day pillar is the closest of the four to you: the stem is you (the Day Master) and the branch is your spouse palace. The Wu-Yin pillar is therefore about the relationship between "Wu Earth the person" and "Yin the partner".

What Wu-Yin people are like
The Day Master Wu Earth sets the base tone: With Wu Earth as your Day Master, you are like a mountain: your very presence puts people at ease. You are steady and true to your word, not one to go back on a promise, and everyone in your circle regards you as someone they can rely on. You do not chase the flashy; you go step by step, feet firmly on the ground, and the more unsettled the environment, the more your composure proves its worth.
The day branch Yin has Seven Killings as its main qi, and that is the layer Wu-Yin adds on top of the Day Master: Sitting on the Seven Killings star brings fast decisions and a strong will; in a crisis these are the people who hold the line. The strength is action and resilience, suited to roles that lead or decide. Watch for a short fuse, resistance to being managed and high demands on self and others; slowing down by half a beat helps relationships.
Women and men: traditionally a woman's chart reads the husband star (the Officers) and a man's the wife star (Wealth). For a Wu-Yin woman, the husband star Seven Killings sits right in the spouse palace as its main qi, so a partner looms large in daily life; for a Wu-Yin man, the wife star (Wealth) is not in the spouse palace, so look to the other pillars and the luck cycles. This only describes what tends to show up in relationships; see "The spouse star of Wu-Yin for men and women" below.
Personality is read from the whole chart; the day pillar is only its core. Two people with the same pillar can come across very differently once the month and the other pillars are added.

What is the structure of Wu-Yin?
Wu-Yin is the stem Wu over the branch Yin. Wu is Yang Earth and is your Day Master, standing for you; Yin is Wood and sits in the day branch, which is the spouse palace. The relation between the two therefore says two things at once: the grain of the person, and their default position inside an intimate relationship.
Hidden stems and Ten Gods: where the real weight sits
Each branch holds stems that are not written on the face of the chart, yet they decide how much each Ten God actually weighs. Yin holds 甲, 丙, 戊, which to the Day Master Wu Earth are:
The main qi carries the most weight, so the spouse palace of Wu-Yin mainly shows the face of Seven Killings; the middle and residual stems are undertones that surface when a Luck Pillar or annual pillar stirs them.
How the stem and branch of Wu-Yin relate: branch controls stem ("cut feet")
| Stem | Wu (Earth) |
|---|---|
| Main hidden stem of the branch | Jia (Wood) |
| Stem–branch relation | branch controls stem ("cut feet") |
| Life Stage on its own branch | Birth |
| Root | residual stem Wu: shallow root |
The branch element Wood turns around and controls the stem element Earth; classical texts call this "cut feet", and the Day Master sits on an Officer star. High standards, a heavy sense of duty and a habit of setting rules for oneself; pressure tends to come from the closest relationship or from rules at work, and learning to ease off often matters more than trying harder.
Wu sitting on Yin: the "Birth" stage and the root
Birth is a seed just sprouting: staying power, eagerness to learn, endurance and helpful mentors; a steady start that gets smoother with time.
The Life Stages describe the state of momentum; this site judges a strong or weak Day Master by hidden-stem roots, not by the stages. See the full cycle of every stem on Twelve Life Stages.
From our engine: how strong Wu-Yin Day Masters tend to be
| Sample | 280 charts (one per day, 1960–2005; 16,802 in all) |
|---|---|
| Strong / balanced / weak | 22.9% / 44.6% / 32.5% |
| Average strong share, six Wu Earth pillars | 27.7%; Wu-Yin sits within 5 points of that average |
| Most common first useful element | Fire 61.8%, Metal 26.8% |
The day pillar is one pillar of four; a person’s strength still depends on the month and the whole chart. These figures show which way sitting on Yin pushes the Day Master. Method on Strong and Weak Day Masters.
Spouse palace in Yin: partner tendencies and how to get on
The partner：The partner is driven and ambitious, restless, with a lot going on outside the home. Yin is Yang Wood: growing upward is its nature, and they need a stage of their own, not only the household.
Where to put the effort：Accept the outward-facing side; insisting on constant closeness costs you both. In exchange, turn "home by when" into a clear agreement. They respect rules, and they pull further away from emotional pressure.
Worth saying plainly: the spouse palace describes a tendency, not who a person is bound to meet. It reads more like a map of the routes you take easily inside a relationship; knowing it saves a few wrong turns.
The spouse star of Wu-Yin for men and women
Traditionally a man’s wife star is Wealth and a woman’s husband star is Officer or Seven Killings; the question is whether that star sits inside the spouse palace (the day branch). For Wu-Yin:
| Place in Yin | Reading | |
|---|---|---|
| Male chart (wife star: Wealth) | none | none of the hidden stems of Yin is a Wealth star; the spouse palace holds Seven Killings instead. That does not mean no marriage — the wife star is found in other pillars or arrives with luck cycles and years. |
| Female chart (husband star: Officer) | main stem, Seven Killings | the main hidden stem of Yin is Seven Killings, so the husband star sits right in the spouse palace and a partner has a strong presence; often forceful and bold, with a period of adjustment before things settle. |
Many modern readers look at the spouse palace as a whole regardless of gender; the spouse star is one angle and should be read with the full chart.
Years that touch the Yin spouse palace, 2026–2037
The day branch is the spouse palace. When a year’s branch clashes, combines, punishes or harms it, matters of love and home are more easily stirred. The next twelve years:
| Clash | 2028 Wu-Shen |
|---|---|
| Six Harmony | 2031 Xin-Hai |
| Three Harmony | 2026 Bing-Wu, 2030 Geng-Xu |
| Punishment | 2028 Wu-Shen, 2037 Ding-Si |
| Harm | 2037 Ding-Si |
Heaven strikes, earth clashes: in 2064 (Jia-Shen) the year stem Jia attacks the Day Master Wu while the branch Shen clashes Yin — a once-in-sixty-years year of upheaval for this pillar.
Hidden echo (fu yin): 2058 is a Wu-Yin year again, identical to the day pillar; classical texts read it as repetition and old matters returning.
A year is only a trigger; good or bad depends on the luck cycle and the whole chart, so no single year decides anything. Zodiac-by-zodiac clashes are on Tai Sui.
Special structures in Wu-Yin
Yin-Yang Mismatch
The classical view：Classically called Yin-Yang Mismatch, said to bring a bumpy marriage and thin ties with the spouse’s family.
In plain terms：What the old name was usually flagging is two things: timing that tends to fall out of step, and hard work getting on with the in-laws, not a verdict that the marriage is bad.
Proportion：This is something to watch, not a sentence. Marrying later, spending longer together first, and settling expectations between the two families early will, in practice, usually see it through. Do not let the name frighten you: alarming names are endemic to this class of star.
Na Yin: City Wall Earth
City Wall Earth: ramparts of jade for the heavenly capital, a golden fortress for the imperial city.
The earth packed into a city wall, solid and defensible, guarding all within. Steady and dependable, principled and mindful of limits, it can shoulder responsibility and give others a sense of safety.
Each Na Yin is shared by two pillars: Wu-Yin shares City Wall Earth with Ji-Mao. It is a supporting layer of imagery, useful for overall flavor, but it does not override the main line set by the Day Master and the spouse palace.
Void branches: Shen, You
Wu-Yin belongs to the Jia-Xu decade, which never reaches the branches Shen, You; these are its void branches. Whatever a voided pillar stands for tends to be "present but not solid": not absent, but hard to hold, or late in arriving. In practice it matters which pillar is voided and whether it is clashed or combined; the fact alone settles nothing.

Wu-Yin day pillar FAQ
What is the personality of the Wu-Yin day pillar?
The Day Master Wu Earth is the subject: With Wu Earth as your Day Master, you are like a mountain: your very presence puts people at ease. The day branch Yin is the spouse palace and stands as Seven Killings to the Day Master, adding a second layer. Personality is read from the whole chart; the day pillar is only its most central part.
What kind of partner does the Wu-Yin day pillar suggest?
The partner is driven and ambitious, restless, with a lot going on outside the home. Yin is Yang Wood: growing upward is its nature, and they need a stage of their own, not only the household.
Is the Wu-Yin day pillar good or bad?
No day pillar is inherently good or bad. The spouse palace star of Wu-Yin is Seven Killings, which names a pattern of relating, not a score. What actually decides how smoothly things run is the balance of the whole chart and the Luck Pillar, not one pillar.
What are the void branches of Wu-Yin?
Wu-Yin belongs to the Jia-Xu decade, so its void branches are Shen, You. Which pillar the void lands on, and whether it is stirred by a clash or combination, is what matters; the bare fact decides nothing.
