Ding-Si Day Pillar: Ding Fire over Si Fire, Spouse Palace Rob Wealth
What are Ding-Si people like? With Ding Fire as your Day Master, you are like a candle flame: never showy, yet giving off just the right warmth to those in the dark. Your day branch holds Rob Wealth, so you act fast, stand by your friends and like to win. In our sample of 280 Ding-Si charts, 14.6% are strong and 37.9% 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 Ding-Si pillar is therefore about the relationship between "Ding Fire the person" and "Si the partner".

What Ding-Si people are like
The Day Master Ding Fire sets the base tone: With Ding Fire as your Day Master, you are like a candle flame: never showy, yet giving off just the right warmth to those in the dark. Your mind is finely tuned and your feelings run deep; you catch the smallest shifts in other people's moods, which is why friends so often come to you to confide. You seem gentle and quiet on the outside, but inside you hold clear opinions and firm convictions, the soft-outside, warm-inside type.
The day branch Si has Rob Wealth as its main qi, and that is the layer Ding-Si adds on top of the Day Master: Sitting on the Rob Wealth star brings quick reactions and nerve, a wide circle of friends and loyalty; these are often the people who get a group moving. The strength is drive and follow-through. Watch for impulse and comparison: spending, investing and promises can be made on a whim, and in any partnership it pays to put roles and money in writing.
Women and men: traditionally a woman's chart reads the husband star (the Officers) and a man's the wife star (Wealth). For a Ding-Si woman, the husband star (the Officers) is not in the spouse palace, so look to the other pillars and the luck cycles; for a Ding-Si man, the wife star Direct Wealth is hidden in the spouse palace as its residual qi, so the bond needs time and care to surface. This only describes what tends to show up in relationships; see "The spouse star of Ding-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 Ding-Si?
Ding-Si is the stem Ding over the branch Si. Ding is Yin Fire 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 Ding Fire are:
The main qi carries the most weight, so the spouse palace of Ding-Si mainly shows the face of Rob Wealth; the middle and residual stems are undertones that surface when a Luck Pillar or annual pillar stirs them.
How the stem and branch of Ding-Si relate: same element
| Stem | Ding (Fire) |
|---|---|
| Main hidden stem of the branch | Bing (Fire) |
| Stem–branch relation | same element |
| Life Stage on its own branch | Peak |
| Root | main stem Bing: deep root |
The stem and the branch share the element Fire, which classical texts call "stem and branch of one breath". The Day Master sits right on its own root: steady, self-directed and not much in need of outside backing — but also slower to take advice. The spouse palace holds a peer star (Friend or Rob Wealth), so a partner can feel like a teammate and a rival at once; learning to yield helps.
Ding sitting on Si: the "Peak" stage and the root
Peak is where strength is fullest: the strongest opinions and the most drive, able to carry a load — and, when too rigid, prone to head-on clashes.
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 Ding-Si Day Masters tend to be
| Sample | 280 charts (one per day, 1960–2005; 16,802 in all) |
|---|---|
| Strong / balanced / weak | 14.6% / 47.5% / 37.9% |
| Average strong share, six Ding Fire pillars | 14.8%; Ding-Si sits within 5 points of that average |
| Most common first useful element | Wood 59.3%, Earth 22.5% |
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 Ding-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 Ding-Si:
| Place in Si | Reading | |
|---|---|---|
| Male chart (wife star: Wealth) | residual stem, Direct Wealth | the wife star Direct Wealth is hidden in the residual stem of Si: present but not prominent, so the bond tends to surface with time and care. |
| Female chart (husband star: Officer) | none | none of the hidden stems of Si is an Officer star; the spouse palace holds Rob Wealth instead. Look to the other pillars and to when luck cycles and years bring an Officer star in. |
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 2043 (Gui-Hai) the year stem Gui attacks the Day Master Ding while the branch Hai clashes Si — a once-in-sixty-years year of upheaval for this pillar.
Hidden echo (fu yin): 2037 is a Ding-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.
Na Yin: Sand Earth
Sand Earth: heaped where the waves recede, formed along the shoals.
A sandbar heaped up where the waves draw back, loose to look at, yet able to gather much from little. Low-key and quietly deep, able to endure solitude, its achievements pile up bit by bit.
Each Na Yin is shared by two pillars: Ding-Si shares Sand Earth with Bing-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: Zi, Chou
Ding-Si belongs to the Jia-Yin decade, which never reaches the branches Zi, Chou; 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.
