Saju compatibility (gunghap): how two charts are matched

What gunghap reads

Compatibility in saju starts from two complete charts, not two signs. The core question: does what one chart lacks, the other supply? A chart thirsty for water and a chart rich in it tend to steady each other; two charts loaded with the same element can amplify a shared blind spot.

On top of element balance, a reader looks at how the two day pillars relate, and whether the branches form supportive combinations or tense clashes. It’s an ecology, read across two people.

Where the score comes from

A compatibility score isn’t a vibe — it’s built from concrete factors: how well the two charts complement each other’s elements, the relationship between the day masters, and the balance of combinations versus clashes between branches.

Because those factors are computable, the score can show its work. We compute the number deterministically and hand back the reasons behind it, instead of asking you to take a single figure on faith.

A high score isn’t the whole story

Compatibility describes the terrain two people walk, not a verdict on the relationship. A high score points to natural ease; a lower one names the frictions — workable once you can see them. Plenty of strong relationships run on charts that have to meet each other halfway.

Not just for romance

The same reading works for friends, family and business partners. Anywhere two people’s temperaments and timing have to mesh, gunghap has something to say — which is why it’s a natural thing to check for the group chat, not only for couples.
