Two charts, read together.
Five classical dimensions of compatibility reading. Day Master meeting, year-branch resonance, spouse-palace harmony, elemental complementarity, and life-phase rhythm. Descriptive, not deterministic — and never weaponized.

What 合婚 actually is
The classical Chinese practice of he hun (合婚) — "marriage matching" — has been around for at least a thousand years. In its restrained academic form, it compares two charts across well-defined dimensions: how the Day Masters meet, how the year branches resonate, what the spouse palaces (day branches) say, how the five elements complement, and how the current luck pillars synchronize.
In its weaponized form — which is how it usually shows up in modern marketing — it produces a "compatibility score" used to forbid a marriage, sell a "remedy," or coerce a family. We refuse all three of those uses. The number we produce is a literature-based descriptive summary, not an instruction. Read it for what it is.

The five dimensions, briefly
- Day Master meeting (日主相会) — the most important. Whether the two stems combine, generate, or control each other.
- Year branch resonance (年柱相应) — Six Harmony, Six Clash, or Three Harmony trine.
- Spouse palace (夫妻宫) — the day branch is each person's "spouse seat." Harmony here tends to mean familiarity early.
- Elemental balance (五行互补) — whether one of you supplies the element the other is missing.
- Life-phase rhythm (大运同步) — whether your current decade-level luck pillars are aligned, generative, or in friction.

What this reading is not
It is not a prediction of marriage outcome. It is not a verdict on whether you should be together. It is not a remedy to sell. It is a translation of what five corners of the literature have noticed about pairings of the configuration you both happen to carry.
