Xin-Si Day Pillar: Xin Metal over Si Fire, Spouse Palace Direct Officer
What are Xin-Si people like? With Xin Metal as your Day Master, you are like a piece of jade polished with great care, born with a refined quality and finely tuned antennae. Your day branch holds Direct Officer, so you are disciplined, principled and responsible. In our sample of 280 Xin-Si charts, 24.3% are strong and 25.7% 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 Xin-Si pillar is therefore about the relationship between "Xin Metal the person" and "Si the partner".

What Xin-Si people are like
The Day Master Xin Metal sets the base tone: With Xin Metal as your Day Master, you are like a piece of jade polished with great care, born with a refined quality and finely tuned antennae. You have standards for quality and hold firm on the details; whether it is the results of your work or the taste of your daily life, you will not let yourself be careless. Your powers of observation and your eye for beauty stand out, and you often notice the fine points others overlook; your thinking is clear and cool, and your judgment at the crucial moment tends to cut straight to the heart of things.
The day branch Si has Direct Officer as its main qi, and that is the layer Xin-Si adds on top of the Day Master: Sitting on the Direct Officer star makes for a sense of proportion, care for reputation and promises, and being trusted with work that needs trust. The strength is reliability and integrity. Watch for stiffness and self-imposed pressure; allowing a little imperfection makes for an easier life.
Women and men: traditionally a woman's chart reads the husband star (the Officers) and a man's the wife star (Wealth). For a Xin-Si woman, the husband star Direct Officer sits right in the spouse palace as its main qi, so a partner looms large in daily life; for a Xin-Si 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 Xin-Si 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 Xin-Si?
Xin-Si is the stem Xin over the branch Si. Xin is Yin Metal and is your Day Master, standing for you; Si is Fire 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. Si holds 丙, 戊, 庚, which to the Day Master Xin Metal are:
The main qi carries the most weight, so the spouse palace of Xin-Si mainly shows the face of Direct Officer; the middle and residual stems are undertones that surface when a Luck Pillar or annual pillar stirs them.
How the stem and branch of Xin-Si relate: branch controls stem ("cut feet")
| Stem | Xin (Metal) |
|---|---|
| Main hidden stem of the branch | Bing (Fire) |
| Stem–branch relation | branch controls stem ("cut feet") |
| Life Stage on its own branch | Death |
| Root | residual stem Geng: shallow root |
The branch element Fire turns around and controls the stem element Metal; 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.
Xin sitting on Si: the "Death" stage and the root
Death sounds alarming but means "momentum at rest": quiet, focused, able to dig into one subject for a long time without fanfare.
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 Xin-Si Day Masters tend to be
| Sample | 280 charts (one per day, 1960–2005; 16,802 in all) |
|---|---|
| Strong / balanced / weak | 24.3% / 50% / 25.7% |
| Average strong share, six Xin Metal pillars | 24.9%; Xin-Si sits within 5 points of that average |
| Most common first useful element | Earth 60%, Water 28.6% |
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 Si pushes the Day Master. Method on Strong and Weak Day Masters.
Spouse palace in Si: partner tendencies and how to get on
The partner：The partner is clever and articulate, conscious of image, quick to think and careful to calculate, and very capable in public. Si is Yin Fire: it burns inside, so the outside can look composed.
Where to put the effort：Saving face comes first; undercutting them in front of others does far more damage than you would expect. They persuade with reasons, so answering only with emotion will not connect. Translate the feeling into a reason they can follow.
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 Xin-Si 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 Xin-Si:
| Place in Si | Reading | |
|---|---|---|
| Male chart (wife star: Wealth) | none | none of the hidden stems of Si is a Wealth star; the spouse palace holds Direct Officer 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, Direct Officer | the main hidden stem of Si is Direct Officer, so the husband star sits right in the spouse palace and a partner has a strong presence; often steady and principled, playing a supporting role in the relationship. |
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 Si 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 | 2031 Xin-Hai |
|---|---|
| Six Harmony | 2028 Wu-Shen |
| Three Harmony | 2029 Ji-You, 2033 Gui-Chou |
| Punishment | 2028 Wu-Shen, 2034 Jia-Yin |
| Harm | 2034 Jia-Yin |
Heaven strikes, earth clashes: in 2067 (Ding-Hai) the year stem Ding attacks the Day Master Xin while the branch Hai clashes Si — a once-in-sixty-years year of upheaval for this pillar.
Hidden echo (fu yin): 2061 is a Xin-Si 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 Xin-Si
Ten Evils Great Defeat
The classical view：Classically called Ten Evils Great Defeat, a frightening name for what is simply the Day Master’s prosperity star falling into the void.
In plain terms：The name comes from old date-selection practice and originally meant "the income that should be there is voided": money comes in and goes out rather than accumulating. It is not a verdict that a life is doomed to fail.
Proportion：This is the single most misleading name among all the symbolic stars. In practice, if the chart itself is strong and the Luck Pillar cooperates, the effect is slight. Seeing it is no cause for alarm. Read the whole chart, as always.
Na Yin: White Wax Metal
White Wax Metal: a shard of jade from Kunlun, gold left behind on the banks of the Luo.
Metal still being refined, soft and not yet hardened, tender but not yet strong. Its potential waits to be worked; the early years call for grinding and the right surroundings, and once formed it carries its own sheen.
Each Na Yin is shared by two pillars: Xin-Si shares White Wax Metal with Geng-Chen. 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
Xin-Si 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.

Xin-Si day pillar FAQ
What is the personality of the Xin-Si day pillar?
The Day Master Xin Metal is the subject: With Xin Metal as your Day Master, you are like a piece of jade polished with great care, born with a refined quality and finely tuned antennae. The day branch Si is the spouse palace and stands as Direct Officer 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 Xin-Si day pillar suggest?
The partner is clever and articulate, conscious of image, quick to think and careful to calculate, and very capable in public. Si is Yin Fire: it burns inside, so the outside can look composed.
Is the Xin-Si day pillar good or bad?
No day pillar is inherently good or bad. The spouse palace star of Xin-Si is Direct Officer, 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 Xin-Si?
Xin-Si 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.
