Gui-Si Day Pillar: Gui Water over Si Fire, Spouse Palace Direct 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 Gui-Si pillar is therefore about the relationship between "Gui Water the person" and "Si the partner".

What is the structure of Gui-Si?
Gui-Si is the stem Gui over the branch Si. Gui is Yin Water 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 Gui Water are:
The 本氣 carries the most weight, so the spouse palace of Gui-Si mainly shows the face of Direct 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.
Special structures in Gui-Si
Day Nobility
The classical view：Classically called Day Nobility: the day branch carries the Heavenly Noble star, bringing help from others and a turn for the better in bad moments.
In plain terms：This type readily meets people willing to give them a hand, and often finds an opening at the decisive moment; the road has a little less friction than most.
Proportion：Helpful people amplify what you are already doing; they do not do it for you. With nothing under way there is nothing to help — the classics leave this unsaid, but in practice it is plain.
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: Long-Flowing Water
Long-Flowing Water: rolling on without limit, surging on without cease.
The unbroken flow of a great river, never resting day or night, bound for far places. Patient and able to go the distance, its achievements gather drop by drop over a long, steady course.
Each Na Yin is shared by two pillars: Gui-Si shares Long-Flowing Water with Ren-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: Wu, Wei
Gui-Si belongs to the Jia-Shen decade, which never reaches the branches Wu, Wei; 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.

Gui-Si day pillar FAQ
What is the personality of the Gui-Si day pillar?
The Day Master Gui Water is the subject: With Gui Water as your Day Master, you are like the dew of early morning: silent and soundless, yet able to seep into all things and nourish the earth. The day branch Si is the spouse palace and stands as Direct 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 Gui-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 Gui-Si day pillar good or bad?
No day pillar is inherently good or bad. The spouse palace star of Gui-Si is Direct 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 Gui-Si?
Gui-Si belongs to the Jia-Shen decade, so its void branches are Wu, Wei. Which pillar the void lands on, and whether it is stirred by a clash or combination, is what matters; the bare fact decides nothing.
