Grouping 281 day branches into the three trine (Samhap) sets
Compatibility pays close attention to whether two people's day branches (日支) form a trine (三合) or a clash (沖). The trine groups split the twelve branches into four sets of three — the Fire set (In, O, Sul), Metal set (Sa, Yu, Chuk), Water set (Sin, Ja, Jin), and Wood set (Hae, Myo, Mi). We counted the day branches of 281 Korean singers, actors and K-pop idols whose birthdays we could confirm into these four sets. Perfectly even would be 70.25 people per set.
- Fire set 78 (27.8%) · Metal set 75 (26.7%) · Water set 71 (25.3%) · Wood set 57 (20.3%)
- The gap between the largest (Fire) and smallest (Wood) is 21 people, a 1.37-fold difference.
This is a statistic, not a reading of you. A 1.37-fold gap across 281 people does not mean the Fire set favors a career in entertainment, or that the Wood set is unlucky for compatibility. A sample this size can spread that far by chance alone — we report what we counted and attach no reason to it.
After the trine sets, the six harmony pairs — do they group the same way?
Trine sets (Samhap) are not the only way compatibility reading groups the twelve branches. Six Harmony (Yukhap) pairs them up two at a time into six fixed pairs instead — Rat-Ox, Tiger-Pig, Rabbit-Dog, Dragon-Rooster, Snake-Monkey, Horse-Goat. These six pairs are a fixed classical table, set regardless of any sample size.
So we first compared the pairings themselves — of the six Yukhap pairs, does either branch in a pair ever belong to the «same» Samhap set (Fire, Metal, Water, Wood) as its partner? Checking directly, all six pairs (6/6) land in different Samhap sets — Samhap and Yukhap simply do not group branches the same way. This is a fact about the two classification systems themselves, independent of the 281 people.
- Rat-Ox (Water set · Metal set) · Tiger-Pig (Fire set · Wood set) · Rabbit-Dog (Wood set · Fire set) · Dragon-Rooster (Water set · Metal set) · Snake-Monkey (Metal set · Water set) · Horse-Goat (Fire set · Wood set) — the parentheses show each branch's Samhap set. Every pair spans two different sets.
We then regrouped the same 281 people's day branches by the six Yukhap pairs and added up the counts. Perfectly even would be 46.8 people per pair.
- Tiger-Pig 51 (18.1%) · Rat-Ox 50 (17.8%) · Snake-Monkey 49 (17.4%) · Dragon-Rooster 47 (16.7%) · Horse-Goat 46 (16.4%) · Rabbit-Dog 38 (13.5%)
- The gap between the largest (Tiger-Pig) and smallest (Rabbit-Dog) is 13 people, a 1.34-fold difference — about the same size as the Samhap gap (1.37-fold).
This too is a statistic, not a reading of you. We attach no reason to the 1.34-fold gap either. "The pairs never overlap (6/6)" is a fixed fact of the system itself; "pair sizes differ (1.34x)" is a number that comes from this 281-person sample — we kept these two separate so they are not read as the same kind of claim.

What does a compatibility reading look at?
A compatibility reading sets the two charts side by side. It does not decide a match from the zodiac animal alone — it reads how the eight characters of the year, month, day and hour act on one another.
It looks above all at the day stem (日干) — the energy of the day you were born — against the day branch (日支), the seat of the spouse. Whether those two characters join (合) or clash (沖), and whether one person's Yongsin (用神) arrives from the other, is the heart of it.
The measure used here is the Cheyongron (體用論) of Japyeongjinjeon (子平眞詮): the month command raises the structure of a chart, and the day pillar must be able to carry it. Every term is explained one by one further down this page.
The same two people always return the same result. And we do not rank anyone — no pair is set against another as the better match.
⚠ What we hand you here is material read by the measure of the classics. What the two of you do is yours to decide.

Ⅵ. Mutual dynamics read through the twelve Sinsal (12神殺)
Orthodox Jipyeong Myeongri does not accept the lesser Sinsal (Wonjin, Gwimun-gwan and the like) or Samjae (三災) readings, which lack scholarly grounding. We do not carry them.
These are carried in the compatibility reading because the twelve Sinsal (神殺) describe the temperament and the rhythm of daily life each person is born with — the sociability of Dohwa, the mobility of Yeokma, the drive of Jangseong — which is exactly where two people meet or rub against each other in practice. They are read as material alongside the structural judgement, not as a verdict of their own.
