What this pillar describes
Yang Wood Rat is a stem-branch pair, not a standalone personality type. The heavenly stem shows the visible qi on top; the earthly branch shows the seasonal container underneath. The hidden stems inside the branch explain why a pillar can carry more than one layer of meaning.
The Rat branch belongs to mid-winter and carries hidden stem 癸. In a real reading, Pillarwise weighs this pillar against the day master, season, Ten Gods, roots, combinations, and clashes before drawing any life-area meaning.
In practice, the same Jiazi pillar reads differently when it appears as a year pillar, month pillar, day pillar, or hour pillar. Pillarwise keeps this page as a deterministic reference, then lets the calculator decide how the pillar behaves inside the whole chart.
How Pillarwise uses this reference
First identify where 甲子 appears: year, month, day, hour, luck pillar, or annual timing. The same row is data; the chart position gives it function.
The branch is checked for combinations, clashes, harms, and roots against the rest of the chart. Those relationships decide whether the pillar supports, exposes, or redirects a pattern.
The stem and hidden stems become Ten Gods only after they are compared to the day master. That is why this page avoids turning a single pillar into a fixed verdict.
