辛酉

Yin Metal Rooster

Xīn–Yǒu

This is one fixed meeting of a Heavenly Stem and an Earthly Branch. The stem supplies yin Metal; the branch supplies the Rooster and its twelve-position time coordinate.

Two coordinates, read together

What is fixed inside 辛酉

A pillar keeps the same stem and branch wherever it is used. What changes is its placement—as a year, month, day or hour—and the other pillars it is compared with.

01 · Visible stem

Xin

Yin Metal, stem 8 in the ten-stem sequence.

02 · Phase relation

Reinforcing

The stem and branch both carry Metal, so this pair repeats one phase rather than linking two phases.

A separate traditional association · 纳音

Pomegranate wood

Na Yin assigns one named image and phase to every pair of consecutive cycle pillars. It sits beside the visible stem and branch coordinates; it does not replace either one.

The You coordinate

The same branch names an animal, a double hour, a solar-term month and a compass sector. Those coordinates remain attached to in every pillar that contains it.

A coordinate, not a complete reading

What this pillar establishes

辛酉 fixes one stem–branch identity. A chart supplies the placement and comparisons that make that identity usable.

The pair fixes

  • Yin Metal through
  • The Rooster branch and its time coordinates
  • 石榴木 Pomegranate wood as its Na Yin
  • Position 58 in the repeating sequence

The chart still decides

Whether the pair is the year, month, day or hour pillar; which stem is the Day Master; and how the surrounding stems and branches relate to it. The pair alone does not rank a personality, promise an outcome or stand in for the other three pillars.
