A polished silver blade gleaming in the last light of an October evening.
Sin-yu is metal on metal: the jewel, 辛, on the Rooster, 酉, pure refined metal in mid autumn. The stage is Taking office. The picture is polished silver at dusk, sharp, bright and clean.
People with this day pillar are often described as refined, precise and self possessed, with high standards and a sharp eye. You sit on the Peer, read as a firm sense of self. The tradition sees elegance, clarity and a cool independence.
With others you tend to be discerning and honest, and you may be slow to trust. The growth point is warmth: polished metal is beautiful and cold to the touch, so let people feel your warmth too.

What sits inside Sin-yu
The branch 酉 Yu holds hidden stems (지장간 jijanggan). Seen from the day master 辛, each one takes a ten god role. The last one listed is the main stem, so this pillar is said to sit on the Peer. Same element, same polarity as you: friends, equals, and your own independent streak.
| Hidden stem | Ten god for 辛 |
|---|---|
| 庚 Gyeong, yang metal (10 days) | Rival 겁재 |
| 辛 Sin, yin metal (20 days) | Peer 비견 |
In the twelve stage life cycle (십이운성 sibi unseong), 辛 in 酉 stands at Taking office (건록 建祿): the stem takes up its post, read as self reliance and steady strength in its own ground.
A question to sit with
Where could you let warmth show through the polish?
