A polished stone flashing in strong late morning sunlight at the start of summer.
Sin-sa places the jewel, 辛, on the Snake, 巳, fire at the start of summer. Fire controls metal, and a jewel in sunlight is exactly where it sparkles most. The picture is poise under heat, polish on display.
People with this day pillar are often described as elegant, sharp and composed, with a strong sense of propriety. You sit on Order, which the tradition reads as respect for structure, a good name and fair rules. The Snake also hides metal and earth, so there is resilience under the shine.
With others you tend to be charming, courteous and discerning. You may hold yourself to very high standards. The growth point is shade: sparkle takes energy, and not every moment needs to be your best one.

What sits inside Sin-sa
The branch 巳 Sa 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 Order. What controls your element, opposite polarity: structure, duty, reputation and fair rules.
| Hidden stem | Ten god for 辛 |
|---|---|
| 戊 Mu, yang earth (7 days) | Mentor 정인 |
| 庚 Gyeong, yang metal (7 days) | Rival 겁재 |
| 丙 Byeong, yang fire (16 days) | Order 정관 |
In the twelve stage life cycle (십이운성 sibi unseong), 辛 in 巳 stands at Stillness (사 死): movement stops, read as focus, depth and an ability to stay with one thing.
