Introduction to Bazi Compatibility
One of the most popular applications of Bazi astrology is relationship compatibility analysis. For centuries, families in China have consulted Bazi masters before arranging marriages, seeking to understand whether two people would live harmoniously together.
The Day Master Connection
The most important factor in Bazi compatibility is the relationship between the two Day Masters (日主). Your Day Master is the Heavenly Stem of your Day Pillar—it represents your core self.
Favorable Day Master Combinations
Some Day Master pairings naturally complement each other:
- 甲 (Yang Wood) + 己 (Yin Earth): Wood controls Earth, creating a productive tension
- 乙 (Yin Wood) + 庚 (Yang Metal): Metal controls Wood, but with attraction
- 丙 (Yang Fire) + 辛 (Yin Metal): Fire and Metal create passion
- 丁 (Yin Fire) + 壬 (Yang Water): Water controls Fire with balance
- 戊 (Yang Earth) + 癸 (Yin Water): Earth controls Water harmoniously
Element Compatibility
Beyond Day Masters, the overall elemental balance between two charts is crucial:
Complementary Elements
- Partners who have elements the other lacks can help each other achieve balance
- Supporting elements (from the generating cycle) create harmony
- A Water person can benefit from a Metal partner (Metal generates Water)
Challenging Combinations
- Two charts dominated by the same element may clash
- Controlling elements without supporting factors can create conflict
- Too much Fire meeting too much Water may lead to constant struggles
The Six Harmonies (六合)
Bazi recognizes six pairs of Earthly Branches that create harmony:
- 子丑 (Rat-Ox): Creates Earth energy
- 寅亥 (Tiger-Pig): Creates Wood energy
- 卯戌 (Rabbit-Dog): Creates Fire energy
- 辰酉 (Dragon-Rooster): Creates Metal energy
- 巳申 (Snake-Monkey): Creates Water energy
- 午未 (Horse-Goat): Creates Fire/Earth energy
If your Day Branch harmonizes with your partner's Day Branch, it indicates natural compatibility.
The Three Harmonies (三合)
Three branches that form a triangle of compatible energy:
- 申子辰 (Monkey-Rat-Dragon): Water frame
- 巳酉丑 (Snake-Rooster-Ox): Metal frame
- 寅午戌 (Tiger-Horse-Dog): Fire frame
- 亥卯未 (Pig-Rabbit-Goat): Wood frame
Partners sharing the same frame often understand each other intuitively.
Clash and Punishment Relationships
The Six Clashes (六冲)
These branch combinations create conflict:
- 子午 (Rat-Horse)
- 丑未 (Ox-Goat)
- 寅申 (Tiger-Monkey)
- 卯酉 (Rabbit-Rooster)
- 辰戌 (Dragon-Dog)
- 巳亥 (Snake-Pig)
Clashes don't mean a relationship is doomed, but they indicate areas requiring extra effort.
The Three Punishments (三刑)
More challenging combinations:
- 寅巳申 (Tiger-Snake-Monkey)
- 丑戌未 (Ox-Dog-Goat)
- 子卯 (Rat-Rabbit)
Analyzing Specific Life Aspects
Communication Compatibility
Compare the Month Pillars—this shows how you communicate and approach life decisions together.
Emotional Connection
The Day Pillar relationship indicates the depth of emotional and physical connection.
Long-term Stability
Look at the overall chart balance and how the 10-year luck cycles (大运) of both partners interact.
Family Harmony
Year Pillars show how your families might interact and whether in-law relationships will be smooth.
Improving Compatibility
Even challenging combinations can work with awareness:
- Understand your differences: Knowledge is power in relationships
- Find common elements: Focus on areas of natural harmony
- Time important events: Use auspicious dates for major decisions
- Environment adjustments: Live in directions favorable to both
- Communication: Use your understanding to prevent conflicts
Beyond Romance
Bazi compatibility applies to all relationships:
- Business partnerships
- Friendships
- Parent-child relationships
- Employer-employee dynamics

Remember, Bazi compatibility is a guide, not a verdict. Many "incompatible" couples thrive through understanding and effort, while "compatible" couples still need to work on their relationships.
True compatibility comes from mutual respect, communication, and willingness to grow together—Bazi simply helps you understand your natural dynamics better.
