BaZi compatibility
Free BaZi compatibility test: how to read whether two people fit
A BaZi compatibility reading never looks only at whether the zodiac signs pair up. It sets several interactions between the two charts side by side and reads them together.

Whether two people fit comes down to the interaction between their Day Masters, the relation between the marriage palaces, whether the five elements complement each other, and whether the spouse stars show up — with the nayin and the zodiac signs layered on top.
The layers a compatibility reading covers
The usual ones are: the relation between the zodiac signs, the nayin five elements, the producing and overcoming of the Day Masters, the combining or clashing of the marriage palaces, the complementarity of the five elements, and the state of the spouse stars.
Each layer is only a partial signal. What is genuinely useful is the combined score and the specific points of friction.
The zodiac signs and the nayin suit as outer reference; the Day Masters, the marriage palaces and the complementarity of the five elements sit closer to how the energy actually flows in daily life. Concluding from one clash of signs alone is usually too coarse.
The Day Masters show how the two of you take each other in
The Day Master stands for each person's basic temperament. One person's Day Master may support the other, or it may restrain, drain or hold the other in check.
Support is not automatically the best, and restraint is not automatically bad. The point is whether the two can form something that goes both ways: one brings support, the other brings order; one brings drive, the other brings steadiness. Any of these can become a complement.
If the interaction between the two Day Masters shows up over time as one side over-giving while the other keeps drawing on them, boundaries and the division of labour deserve particular attention in real life.
The marriage palaces show how the intimate relationship has to work
Marriage palaces that combine often point to closeness, attraction, or a relationship that easily becomes bound together. Palaces that clash often point to friction over rhythm, over distance and change, over the family environment, or over communication patterns.
Combining is no guarantee of happiness, and clashing is no sentence of separation. Too tight a fit can bring dependence and no room to breathe; a strong clash can push two people out of old patterns and into a new order.
If the marriage palaces flag pressure in the result, the point is not to panic but to see it early: who needs security, who needs room, and how the two of you handle an argument.
Complementary five elements is not simply topping up what is missing
When two people are together, the five elements influence each other. Some people supply the patience, the drive, the expressiveness or the steadiness that the other lacks; others simply amplify what was already over-strong in the other.
Real complementarity is not the elements adding up on paper. It is whether the two make each other more balanced. If one has too much fire and is quick-tempered and the other has well-balanced water and earth, that can bring calm and support — though if the water is over-strong, it can turn into emotional tug-of-war.
So when reading the five elements in a compatibility reading, look at both people's own favourable and unfavourable elements at the same time. An element that helps one person is not necessarily good for the other.
How to read the compatibility score
A high score means the two charts more easily support each other on the traditional dimensions. It does not mean there will never be friction.
A low score does not mean you cannot be together either. More often it tells you that the differences in communication, rhythm or values need to be handled more actively.
More worth looking at than the total is the spread between the dimensions: some couples have strong affinity and weak communication, others have complementary five elements but pressure in the marriage palace. Knowing the specific shortfall is what leaves room to improve.
Which relationships suit a compatibility reading
When you are already talking about engagement, marriage, meeting the parents, buying a home or planning children, a compatibility reading gives you one more angle on the long-term adjustment ahead.
It also helps when the two of you are long distance, of very different ages, from noticeably different backgrounds, or when the same conflict keeps coming back — because it locates whether the problem is one of rhythm, of responsibility, or of expressing your needs differently.
If you have only just met and have not yet settled into being together, a reading can be a reference, but the score should not stand in for real getting-to-know-each-other too early.
How to make good use of the result
Treat it as a mirror for looking at the relationship, to help you see the deepest point of affinity and the main point of friction.
If the result flags pressure from work affecting the relationship, talk about the division of labour and the time early. If it flags different views on money, talk about the budget, saving and risk early. If it flags emotional pressure in communication, establish how you repair things after a row.
As for the relationship itself in real life, it still has to be built on trust, communication, responsibility and growing together. A chart can remind you, but it cannot love for you.
How to start
- 1Enter the birth date, month, day and hour of each of you.
- 2First confirm that both birth hours are accurate, especially if either falls near an hour boundary.
- 3Read the overall score, and then the individual dimensions: zodiac signs, nayin, Day Masters, marriage palaces, complementary five elements.
- 4Read the strongest points of affinity carefully, to understand why you are drawn to each other.
- 5Find the main points of friction, and take them down to communication, money, family and daily rhythm.
- 6Take the advice back into real life, and let the score decide for you.
Common misconceptions
- Writing off a relationship because the zodiac signs clash.
- Treating the compatibility score as the standard for breaking up or getting married.
- Reading only the total and not seeing which dimension is strong and which is weak.
- Changing the birth hour at will to get a better result.
- Ignoring the actual quality of how the two of you live together.

Frequently asked questions
Yes. A compatibility reading is a reference; what the marriage really depends on is communication, responsibility and the work of building it together.
The score is only a general reference. What matters more is seeing the specific strengths and the places that need working on.
