A torch burning bright in the heat of a late May morning.
Jeong-sa is fire on fire: the lamp flame, 丁, on the Snake, 巳, fire at the start of summer. The stage is Peak. The picture is a torch in the heat, focused and intense.
People with this day pillar are often described as passionate, sharp and determined, with strong feelings and quick insight. You sit on the Rival, read as competitive drive and a powerful sense of self. The Snake hides metal and earth, which the tradition reads as practical talent and a clever streak.
With others you tend to be warm, loyal and intense. You may love and argue with the same energy. The growth point is cooling: a flame in summer needs shade and water to stay steady.

What sits inside Jeong-sa
The branch 巳 Sa holds hidden stems (지장간 jijanggan). Seen from the day master 丁, each one takes a ten god role. The last one listed is the main stem, so this pillar is said to sit on the Rival. Your element with the opposite polarity: competitors, bold moves and the urge to win.
| Hidden stem | Ten god for 丁 |
|---|---|
| 戊 Mu, yang earth (7 days) | Performer 상관 |
| 庚 Gyeong, yang metal (7 days) | Steward 정재 |
| 丙 Byeong, yang fire (16 days) | Rival 겁재 |
In the twelve stage life cycle (십이운성 sibi unseong), 丁 in 巳 stands at Peak (제왕 帝旺): the stem at the height of its power, read as strong will, energy and a need for balance.
