Jia-Yin Day Pillar: Jia Wood over Yin Wood, Spouse Palace Friend
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 Jia-Yin pillar is therefore about the relationship between "Jia Wood the person" and "Yin the partner".

What is the structure of Jia-Yin?
Jia-Yin is the stem Jia over the branch Yin. Jia is Yang Wood 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 Jia Wood are:
The 本氣 carries the most weight, so the spouse palace of Jia-Yin mainly shows the face of Friend; the middle and residual stems are undertones that surface when a luck cycle or annual pillar stirs them.
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.
Special structures in Jia-Yin
Day Virtue
The classical view：Classically called Day Virtue: kind by nature and thick in good fortune, disliking clashes, punishments, breaks and harms.
In plain terms：This type is generous and disinclined to fight, leaning towards giving ground, which over time accumulates goodwill and opportunity. People hand them things to look after precisely because of that steadiness.
Proportion：Being easy to deal with invites being taken advantage of. Keep the generosity for people who merit it and hold the boundaries that matter — that is not turning hard, it is letting the goodwill last.
Na Yin: Great Stream Water
Great Stream Water: fierce waves beating the bank, breakers rising to the sky.
A rushing great stream, waves striking the bank and surging skyward, flowing with force. Full of drive and brisk by nature, bold to charge ahead; amid the rapids, it should keep a measure of calm.
Each Na Yin is shared by two pillars: Jia-Yin shares Great Stream Water with Yi-Mao. 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
Jia-Yin 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.

Jia-Yin day pillar FAQ
What is the personality of the Jia-Yin day pillar?
The Day Master Jia Wood is the subject: With Jia Wood as your Day Master, you are like a great tree growing toward the sky, carrying a stubborn streak of integrity deep in your bones. The day branch Yin is the spouse palace and stands as Friend 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 Jia-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 Jia-Yin day pillar good or bad?
No day pillar is inherently good or bad. The spouse palace star of Jia-Yin is Friend, 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 Jia-Yin?
Jia-Yin 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.
