Two animals · their fixed branch coordinates
巳酉
Snake and Rooster compatibility
Snake and Rooster sit 4 places apart on the twelve-branch circle. Their compatibility reading begins with that geometry, then adds the phases and trines attached to the two positions.

Read the two branches first
The animal is the familiar label. The branch fixes the position, phase, polarity, month, double-hour and direction used by the comparison.

Inside both branches · 藏干
What Snake and Rooster carry beneath the surface
Each Earthly Branch contains a fixed list of one to three Heavenly Stems. Comparing the two inventories shows whether this pair repeats an exact stem, shares only a phase, or keeps the two internal lists separate.
No exact stem repeats
The two fixed inventories contain no identical Heavenly Stem. Internal phase overlap: Metal.

The named branch relationships
Harmony, trine, meeting, clash, harm, break and punishment are different sets. A pair can appear in more than one, so no match replaces another.

Fire controls Metal
Fire, carried by the first branch, regulates Metal in the controlling cycle. That is a phase link alongside any named branch relation the pair also carries.
This is the phase fixed to each Earthly Branch. A birth year also has a stem phase — for example, Fire Rat or Metal Rat — which is a separate coordinate.
The three-branch groups around the pair
Both point to the Metal trine
A trine is complete only when all three of its branches are present. One or two selected animals locate positions inside that group without inventing its missing members.

From a year pair to a four-pillar chart
What this pair establishes — and what comes next
The comparison establishes the fixed relationship between 巳 and 酉. It does not turn two birth-year animals into a verdict about the whole relationship. In a Four Pillars chart, branches also appear at the month, day and hour layers, and each occurrence meets the rest of both charts.
