Ding-Si Day Pillar: Ding Fire over Si Fire, Spouse Palace Rob Wealth
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 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 本氣 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 cycle or annual pillar stirs them.
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.
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 flavour, 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.

Ding-Si day pillar FAQ
What is the personality of the Ding-Si day pillar?
The Day Master Ding Fire is the subject: 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. The day branch Si is the spouse palace and stands as Rob Wealth 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 Ding-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 Ding-Si day pillar good or bad?
No day pillar is inherently good or bad. The spouse palace star of Ding-Si is Rob Wealth, 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 cycle, not one pillar.
What are the void branches of Ding-Si?
Ding-Si belongs to the Jia-Yin decade, so its void branches are Zi, Chou. Which pillar the void lands on, and whether it is stirred by a clash or combination, is what matters; the bare fact decides nothing.
