Six Harmony (Liuhe) in BaZi: Earthly Branch Pairs Decoded

Six Harmony, or Liuhe (六合), is one of the three fundamental earthly branch interactions in BaZi, each involving a specific pairing of compatible branches. Documented in classical BaZi texts including Yuan Hai Zi Ping (淵海子平), the six harmony framework governs which branches naturally "cooperate" with each other, influencing everything from romantic compatibility to business partnerships and daily fortune. Unlike the more widely discussed triple harmony, which requires all three branches to align, six harmony operates as a straightforward pair—making it the most accessible branch relationship for chart interpretation.

When two six harmony branches appear in your BaZi chart, they don't merely coexist; they interact, transforming each other's energetic quality and creating what practitioners call a "cooperative resonance." This article decodes all six liuhe pairs, explains how they differ from their counterparts (triple harmony and six clash), and shows you how to read them in your own chart and relationships.

What Are the Six Harmony Pairs in BaZi?

The six harmony pairs are predetermined combinations of the twelve earthly branches, where each branch has exactly one harmonic partner. Unlike other branch interactions that depend on context, six harmony is always fixed—if your chart contains both branches of a pair, the harmony activates. Here are all six liuhe pairs:

Note
  1. Rat (子) & Ox (丑) → Earth Element
  2. Tiger (寅) & Pig (亥) → Wood Element
  3. Rabbit (卯) & Dog (戌) → Fire Element
  4. Dragon (辰) & Rooster (酉) → Metal Element
  5. Snake (巳) & Monkey (申) → Water Element
  6. Horse (午) & Goat (未) → Earth Element ("Sun–Moon Harmony")

Each pair harmonizes into a specific element, which is crucial for understanding how the harmony reshapes the branches' influence in your chart. For example, a Rat-Ox harmony doesn't simply add Rat and Ox energies side by side; instead, it generates Earth element qualities, introducing stability, groundedness, and material focus that might not be present if these branches appeared separately.

The term Liuhe literally means "six combine"—referring to the fact that the twelve branches are divided into six pairs. In Chinese astrology and BaZi scholarship, this framework has been used for over 2,000 years to assess compatibility, predict annual trends, and understand interpersonal dynamics.

The Six Liuhe Pairs Decoded — Element by Element

Rat–Ox: The Earth Stability Pair

Rat and Ox form the first six harmony pair, harmonizing into Earth. This pairing is often considered one of the most stable and grounding combinations in BaZi. When these two branches appear together in your chart—whether in the year and month pillar, or day and hour—they create an earthy, practical energy.

Element transformation: The Rat's water nature and Ox's earth nature merge to emphasize stability and material accumulation. People with Rat–Ox harmony in their charts often demonstrate strong financial acumen, loyalty, and a preference for long-term security over short-term gains.

In relationships: Rat–Ox pairs are typically dependable and traditional. They tend to prioritize trust and commitment, making this pairing favorable for marriages that value mutual support and shared resources.

Tiger–Pig: The Wood Growth Pair

Tiger and Pig harmonize into Wood, the element of growth, compassion, and expansion. This is considered one of the most beneficial six harmony pairs in modern relationship contexts.

Element transformation: Both branches have yang and yin water affinities, and their harmonization produces a pure Wood quality emphasizing generosity, creativity, and forward momentum. Charts containing Tiger–Pig harmony often show enhanced intuition and social warmth.

In relationships: Tiger–Pig pairs are known for genuine affection and mutual understanding. They tend to bring out each other's best qualities—the Tiger's courage tempered by the Pig's gentleness, creating balanced partnerships favored in romantic compatibility readings.

Rabbit–Dog: The Fire Passion Pair

Rabbit and Dog form the third six harmony pair, harmonizing into Fire. This pairing governs passion, intellectual clarity, and emotional expression.

Element transformation: The Rabbit's yin wood and Dog's yang fire nature combine to create a bright, communicative Fire energy. People with Rabbit–Dog harmony often excel in creative fields, public speaking, and emotional intelligence.

In relationships: Rabbit–Dog pairs are often lively and communicative. They tend to enjoy shared interests and express affection openly, making this pairing popular in compatibility charts, especially for artistic or socially engaged couples.

Dragon–Rooster: The Metal Authority Pair

Dragon and Rooster harmonize into Metal, associated with precision, ambition, and hierarchical order. This is a pairing that resonates with professional and leadership contexts.

Element transformation: The Dragon's yang earth and Rooster's yin metal nature produce strong Metal qualities—decisiveness, clarity, and authority. Charts with Dragon–Rooster harmony often show enhanced executive ability and a natural command presence.

In relationships: Dragon–Rooster pairs tend toward complementary roles—the Dragon bringing vision, the Rooster providing detailed execution. While not always the most emotionally expressive pairing, they can be highly functional and mutually respectful, particularly in business partnerships or marriages where shared ambition matters.

Snake–Monkey: The Water Wisdom Pair

Snake and Monkey harmonize into Water, the element of adaptability, intelligence, and emotional depth. This pairing is associated with sophisticated thinking and strategic planning.

Element transformation: The Snake's yin fire and Monkey's yang metal nature combine into a deep, adaptable Water energy. People with Snake–Monkey harmony often demonstrate high intelligence, psychological insight, and the ability to navigate complexity with grace.

In relationships: Snake–Monkey pairs tend to be intellectually stimulating and adaptable. They often enjoy mental sparring and shared problem-solving, making this pairing favorable for couples who bond over ideas and shared learning.

Horse–Goat: The Earth Harmony Pair (Sun–Moon Harmony)

Horse and Goat form the sixth six harmony pair, also harmonizing into Earth. This pairing is sometimes called "Sun–Moon Harmony" (太陽太陰合) in classical texts, referring to the celestial balance between masculine (Horse) and feminine (Goat) energies.

Element transformation: The Horse's yang fire and Goat's yin earth nature produce a gentle, nurturing Earth quality—less rigid than Rat–Ox, but more emotionally warm. Charts with Horse–Goat harmony often show enhanced sensitivity, aesthetic appreciation, and caregiving instincts.

In relationships: Horse–Goat pairs are often romantic and aesthetically aligned. They tend to prioritize emotional connection and shared values, making this pairing favorable for relationships centered on mutual care and life enjoyment rather than purely practical compatibility.

How Six Harmony Differs from Triple Harmony and Six Clash

To correctly interpret earthly branch interactions, it's important to understand how six harmony relates to two other key branch dynamics: triple harmony (San He, 三合) and six clash (Liu Chong, 六衝).

Six Harmony vs. Triple Harmony

Triple harmony, or San He, is a deeper but more demanding interaction involving three compatible branches. When all three appear in your chart, they create a powerful, transformative influence.

Key differences:

  • Activation requirement: Six harmony activates with just two branches; triple harmony requires three.
  • Strength: Triple harmony is generally considered more powerful and more transformative. It can even suppress conflicting branches in your chart.
  • Flexibility: Six harmony is more common in everyday readings because any two-branch pairing can activate it. Triple harmony is rarer but more impactful when it occurs.
  • Elemental effect: Both produce elemental transformations, but triple harmony's is more pronounced.

For example, Tiger–Pig six harmony can activate in a year-month or day-hour combination. But if your chart contains Tiger, Rabbit, and Pig (the complete Wood triple harmony), that triple harmony overrides and amplifies the six harmony, producing a much stronger Wood influence.

Six Harmony vs. Six Clash

Six clash (Liu Chong, 六衝) is the opposite dynamic—when two branches oppose each other rather than harmonize. Common clashes include Rat–Horse, Ox–Goat, Tiger–Monkey, and others.

Key differences:

  • Effect direction: Six harmony creates cooperation and transformation; six clash creates friction, instability, and suppression.
  • Energy flow: Harmony branches transform into a unified element; clashing branches remain in opposition, creating internal conflict or external challenges.
  • Practical reading: In a relationship chart, harmony suggests compatibility; clash suggests challenges or need for conscious effort.
  • Chart interpretation: A chart with multiple clashes may show life friction; one with multiple harmonies suggests flow and ease.

Many traditional BaZi readers note that a chart containing both a harmony and a clash involving the same branch must be read carefully—the two interactions can cancel each other out or create complex, context-dependent effects.

Reading Six Harmony in Your BaZi Chart

Where Harmonies Appear

Six harmony pairs activate wherever they appear in your four pillars (year, month, day, and hour). The most impactful positions are typically:

  1. Year–Month harmony: Influences your family background, early life direction, and relationship with parents.
  2. Day–Hour harmony: Affects your personality and closest relationships (spouse, children).
  3. Month–Hour harmony: Colors your work environment and social dynamics.
  4. Year–Hour harmony: Reflects broader life cycles and long-term relationship themes.

A person born on a Tiger day (day pillar Tiger) and a Pig hour (hour pillar Pig) would have Tiger–Pig six harmony, which would strengthen their compassion and forward-thinking nature throughout their life. This harmony appears in their daily personality and immediate family environment.

Harmonic Strength Factors

Not all harmonies are equally powerful:

  • Distance in the chart: Consecutive pillars (e.g., month and day) interact more directly than distant ones (e.g., year and hour).
  • Element support: If the harmonized element (e.g., Earth from Rat–Ox) is also supported by other branches or elements in the chart, the harmony becomes stronger.
  • Clash or clash suppression: If one of the harmony branches also clashes with a third branch, the harmony may be weakened or neutralized.
  • Yin–yang balance: When both branches of a pair appear, their yin–yang relationship matters—timing and relative strength affect harmony activation.

Practical Example

Consider someone with:

  • Year pillar: Rat
  • Month pillar: Ox
  • Day pillar: Tiger
  • Hour pillar: Pig

This person has two six harmony pairs:

  1. Rat–Ox (year–month): Earth stability and financial acumen run through their family background and early life.
  2. Tiger–Pig (day–hour): Wood creativity and compassion shape their personality and closest relationships.

The combination produces a person who is both practical (Earth from Rat–Ox) and creative (Wood from Tiger–Pig), blending financial responsibility with compassionate innovation. They likely grew up in a stable environment but possess artistic sensibilities and genuine warmth in personal relationships.

Six Harmony in Compatibility — Marriage, Friendship, Business

One of the most common applications of six harmony reading is assessing romantic compatibility. When two people have harmonious branches in their charts, or when their birth branches form a six harmony pair, BaZi practitioners often interpret this as a positive compatibility indicator.

Romantic Compatibility

In the context of marriage or romantic partnership, six harmony is frequently assessed by comparing the partners' birth branches (from the year pillar, though day pillar comparison is also used).

Example: A person born in a Rat year and their partner born in an Ox year form a Rat–Ox six harmony. This suggests natural compatibility—the Ox's stability supports the Rat's ambitious nature, and their shared Earth transformation creates a grounded, supportive relationship. Such couples often report feeling "on the same page" and building lasting financial partnerships.

Friendship and Business Partnerships

Six harmony applies beyond romance. In business, Dragon–Rooster harmony pairs (both ambitious and detail-oriented) often excel in leadership roles together. Tiger–Pig pairs bring creative energy to artistic or social enterprises.

Some BaZi practitioners use harmony analysis to form teams:

  • Rat–Ox: Financial advisory, stable business management
  • Tiger–Pig: Creative ventures, human resources, community building
  • Rabbit–Dog: Communications, media, public relations
  • Dragon–Rooster: Executive leadership, strategic planning
  • Snake–Monkey: Consulting, research, complex problem-solving
  • Horse–Goat: Arts, hospitality, caregiving professions

Harmonies and Conflict Resolution

It's worth noting that six harmony doesn't guarantee a conflict-free relationship. Rather, it provides an underlying compatibility that makes cooperation more natural. Couples with strong six harmony often find that conflicts resolve more quickly because they share an intuitive understanding.

Conversely, couples lacking harmony (or with clashing branches) may need to invest more conscious effort into communication, but this doesn't preclude a successful relationship—it simply means the partnership requires awareness and intentionality.

Frequently Asked Questions

Is Six Harmony Stronger Than Triple Harmony?

No. Triple harmony is generally considered the stronger interaction because it involves three branches and produces a more complete elemental transformation. When triple harmony is present in a chart alongside six harmony of the same element, triple harmony dominates the reading. That said, six harmony is more common and still significantly influential in chart interpretation.

Can Six Harmony Cancel Out a Clash?

In some cases, yes—but not completely. If a chart contains both a six harmony pair and a six clash involving one of the branches, the two interact complexly. A common interpretation is that the harmony and clash balance each other, reducing the clarity of both effects. This is why charts with multiple branch interactions require careful, contextual reading rather than simple rule-following.

What Does Rat–Ox Six Harmony Mean for My Chart?

Rat–Ox harmonizes into Earth, adding stability, financial focus, and practical grounding to your chart. If these branches appear in your year and month (family background), you likely experienced security or material stability growing up. If they appear in your day and hour (personal traits), you're probably someone who values savings, loyalty, and long-term planning.

Why Is Horse–Goat Six Harmony Called "Sun–Moon Harmony"?

In classical BaZi texts, the Horse is associated with the sun (masculine, bright, active energy) and the Goat with the moon (feminine, gentle, receptive energy). Their harmony is thus described as a celestial balance. This poetic naming underscores that Horse–Goat harmony is particularly favorable for relationships seeking emotional warmth and mutual care, as it blends solar vitality with lunar gentleness.

How Do I Know If I Have Six Harmony in My Chart?

Check whether any two of your four pillars (year, month, day, hour branches) form one of the six pairs: Rat–Ox, Tiger–Pig, Rabbit–Dog, Dragon–Rooster, Snake–Monkey, or Horse–Goat. If yes, you have six harmony. Our BaZi calculator will identify all your harmonies and clashes automatically, providing a detailed breakdown of their positions and effects.

Can I Use Six Harmony to Choose a Business Partner or Best Friend?

Six harmony is one factor in assessing personal compatibility, but not the only one. Many successful partnerships exist between people whose branches clash or lack harmony—they simply require more intentional communication. However, if you're evaluating multiple potential partnerships, six harmony compatibility is a useful tiebreaker that suggests a more natural, effortless collaboration. For a full compatibility assessment, consult both people's complete BaZi charts, not just birth branches.

Does Six Harmony Affect My Daily or Yearly Fortune?

Yes, indirectly. When annual or daily branches activate a harmony with your birth chart, they can enhance certain areas of your life. For example, if you were born in a Rat year and a Rat year returns (the Year of the Rat), your own branch appears in the cosmic year, which often amplifies your personal themes. If a year's branch harmonizes with one of your pillars (e.g., an Ox year if you were born in a Rat pillar), the harmony can bring ease and support to that life area.
