Ji Chou Day Pillar

Soil upon soil — grounded to the point of stubbornness. Change has never come easily to this one, and it rarely pretends otherwise.

Lightning: enormous, instantaneous, and gone — force without duration.

In the sixty-pillar cycle each image is shared by exactly two pillars. 己丑 shares Fire of the Thunderbolt with 戊子, though the two differ in polarity, animal and hidden stems.

Jǐ carries the image of cultivated field soil. That is this pillar's baseline; the branch it is paired with decides the rest.

Chǒu is Earth, yin in polarity, and carries the Ox.

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

stem and branch share an element (Peer)

Stem and branch pull the same way, which concentrates the pillar's force. Strong-minded and hard to shift — including when shifting would help.

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.
