Wu-Yin Day Pillar: Wu Earth over Yin Wood, Spouse Palace Seven Killings
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 Wu-Yin pillar is therefore about the relationship between "Wu Earth the person" and "Yin the partner".

What is the structure of Wu-Yin?
Wu-Yin is the stem Wu over the branch Yin. Wu is Yang Earth 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 Wu Earth are:
The 本氣 carries the most weight, so the spouse palace of Wu-Yin mainly shows the face of Seven Killings; 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 Wu-Yin
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: City Wall Earth
City Wall Earth: ramparts of jade for the heavenly capital, a golden fortress for the imperial city.
The earth packed into a city wall, solid and defensible, guarding all within. Steady and dependable, principled and mindful of limits, it can shoulder responsibility and give others a sense of safety.
Each Na Yin is shared by two pillars: Wu-Yin shares City Wall Earth with Ji-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: Shen, You
Wu-Yin 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.

Wu-Yin day pillar FAQ
What is the personality of the Wu-Yin day pillar?
The Day Master Wu Earth is the subject: With Wu Earth as your Day Master, you are like a mountain: your very presence puts people at ease. The day branch Yin is the spouse palace and stands as Seven Killings 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 Wu-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 Wu-Yin day pillar good or bad?
No day pillar is inherently good or bad. The spouse palace star of Wu-Yin is Seven Killings, 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 Wu-Yin?
Wu-Yin 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.
