About the compatibility chart
Marriage matching was traditionally graded in three tiers. Traditional Bazi matching looks well beyond the twelve zodiac pairs: it weighs whether the Na Yin elements of the two year pillars generate or overcome each other, how the two day masters interact, whether the day branches — the marriage palace — combine or clash, whether the five elements complement one another, and whether the spouse stars, the wealth star and the officer star, show up for one another at all. Reading two charts side by side this way applies to any relationship between two people, not only to couples.
Wenzhen Dao turns that traditional method into six measurable dimensions: enter two birth dates and you get a compatibility index with a score for every dimension. The AI reading then follows the relationship you choose — love for how you get along and whether you stay together, business for complementary fortunes and the division of roles, friends and family for how deep the bond runs and how you cover for each other, with parenting and workplace relationships each given their own emphasis. It fits dating, preparation for marriage and reflection after it, and equally the careful assessment before working together in business or a reference for how you get on with family and friends.
How to use it
- 1
Enter each person's birth details — date, time and gender, with place of birth optional. Once you are signed in you can also pick people straight from My Charts and have the form filled in for you.
- 2
Press Start Matching and the four pillars, five elements and luck pillars for both people are laid out at once (no sign-in is needed to chart, and true solar time is applied automatically).
- 3
Save the chart, then pick a relationship direction — love, business, friends and family, parenting, work, or an overall overview. The AI reads along that axis in the chat panel, and you can keep asking follow-up questions afterwards.
Frequently asked questions
No. Marriage is the classic case, but the same two-person method works just as well for business partners (do their fortunes complement, who leads and who supports), friends and family (how deep the bond runs, how you cover for each other), parenting and workplace relationships. Save the chart, choose a relationship direction, and the AI reads along that angle.
No. The compatibility index is one reference point taken from the traditional view. It has to be read together with real personality, values and living conditions. Even a modest score can be worked on through understanding and effort.
Exact times are preferable. Without one the day master can still be calculated, but the hour pillar and some marriage palace details are affected. You can start with an approximate hour and regenerate later once the exact time is known.

Compatibility Score
How to read a compatibility score
A compatibility score is an overview of the signals in a relationship. What matters is not the number itself but the dimensions behind it.
Marriage Palace
How Bazi reads the marriage palace
Marriage palace matching looks at how the two day branches relate to each other, and how steady each person's marriage palace sits within their own chart.
Zodiac Pairing
Do the twelve zodiac animals suit each other?
Zodiac pairing is easy to read, but it only looks at the year branch — it cannot stand in for a full compatibility reading, nor say how you get along day to day.
