Geng Chen Day Pillar

Ore in damp earth: well supplied and slow to become anything. Patience is not a virtue for this pillar, it is the mechanism.

Soft, refined metal — clean and workable, not made for bearing weight.

In the sixty-pillar cycle each image is shared by exactly two pillars. 庚辰 shares Refined White Metal with 辛巳, though the two differ in polarity, animal and hidden stems.

Gēng carries the image of unrefined metal — an axe, an ore. That is this pillar's baseline; the branch it is paired with decides the rest.

Chén is Earth, yang in polarity, and carries the Dragon.

Hidden stems: every branch conceals stems of its own, in descending weight — Wù Earth (60%), Yǐ Wood (30%), Guǐ Water (10%).

The ground under this pillar nourishes it. People with it rarely run empty — and can stay comfortable longer than is good for them.

Note: this reads the day pillar alone. A full chart has three more pillars plus the luck cycles, and the balance is only settled by all of them together.
