Two people's birth details
What a BaZi compatibility reading compares
He Hun (合婚, 'joining the marriage') is the traditional practice of setting two people's BaZi charts side by side before a marriage. Modern readers use it for any couple. It does not look for a single 'yes' or 'no'; it asks in which ways the two charts support each other and where they are likely to rub.
Our reading scores six classical dimensions and shows the reason behind every point. Zodiac animals (生肖): whether the year branches combine, clash or are neutral. Day Masters (日干): the relation between the two day stems, including the five stem combinations (天干五合). Spouse palaces (夫妻宮): the day branches, which traditionally stand for the partner. Five elements (五行): whether what one chart lacks the other supplies. Spouse stars (配偶星): whether the Officer or Wealth star each chart looks for is present in the other. Luck Pillars (大運): whether the next twenty years run in similar or opposite directions.
Scores are a way of putting the findings in order, not a verdict. A zodiac clash with strong element complementarity is a common pattern and reads very differently from a clash with nothing else in favour. Read the findings under the score; they say what to watch for.
BaZi compatibility: common questions
- What does a He Hun reading look at?
- The two birth charts together: the zodiac animals, the two Day Masters, the spouse palaces (day branches), the balance of the five elements across both charts, the spouse stars, and the direction of each person's Luck Pillars for the coming years. Each of these is scored by a published rule and explained.
- Our zodiac animals clash. Is that bad?
- A clash between year branches (六沖, such as Rat and Horse) is one factor among six, and the weakest one, because the year branch is the most general part of a chart. Traditional folk sayings about 'incompatible animals' come from this single factor. Many lasting couples clash by animal and match well on Day Master and elements.
- Do we both need our birth hour?
- It helps but is not required. The hour pillar affects the five-element count and the spouse-star check. Without it the reading uses three pillars for that person and says so; the zodiac, Day Master and spouse-palace comparisons are unaffected.
- Does the gender matter?
- Only for two things: which spouse star each chart looks for (traditionally Officer 官 for a woman's chart, Wealth 財 for a man's) and the direction of the Luck Pillars. If you leave gender unset the reading uses a neutral rule and notes it.
- What does a low score mean?
- That the two charts have fewer of the classical points of support, which usually means more differences in temperament or timing to be aware of. It is not a prediction of failure. The findings list says which dimensions scored low and why, which is more useful than the number.
- Is He Hun accurate?
- It is a traditional method, not a measurement. The scoring here follows rules that are stated openly so you can see what each point rests on. Treat it as a structured way to talk about differences, not as a reason to make or break a relationship.
