Can two birth charts tell you whether a relationship will run smoothly? Bazi compatibility analysis (he hun) has been used for exactly that purpose for centuries — long before dating apps, matchmakers in China compared the Eight Characters of prospective couples. The guides in this section explain how it actually works, without superstition: what it means when two Day Masters generate or control each other, why an Earth–Metal pairing feels different from a Fire–Earth one, how the branches of two charts form harmonies and clashes, and what a "good match" does and does not guarantee.
We cover every major Day Master pairing individually — Wood with Fire, Water with Metal, same-element couples, and more — so you can look up your own combination and your partner's directly. Each guide describes the natural dynamic of the pairing, its typical friction points, and concrete ways to work with the differences rather than against them. Bazi compatibility is a map of tendencies, not a verdict; used well, it is one of the most practical applications of the Four Pillars, helping couples understand why they communicate, argue, and support each other the way they do.

Bazi compatibility describes the natural dynamic between two charts — where energy flows easily and where friction is likely. It does not issue verdicts. A challenging pairing can thrive with awareness, and an easy one can drift without effort; the analysis tells you what to work with, not how the story ends.
No. The controlling cycle often shows up in real couples as attraction and productive tension rather than conflict. Day Masters are also only the first layer — branch combinations, elemental balance across both charts, and each person's spouse palace all shift the picture substantially.
Both partners' full birth data: date, time, and place of birth. Accurate birth times matter more here than in most readings, because the day and hour pillars — where the spouse palace sits — carry the most weight in relationship analysis.
