On this site, Qi Men Dun Jia is introduced only as a Chinese cultural and symbolic timing model. It does not constitute decision-making, professional, financial, medical, legal, or personal advice.
1. Symbolic Images of the Heavenly Stems
Qi Men Dun Jia uses the Heavenly Stems as important interpretive symbols. The Ten Heavenly Stems are:
Jia, Yi, Bing, Ding, Wu, Ji, Geng, Xin, Ren, Gui
In a Qi Men chart, the stems express not only yin-yang and Five Element qualities, but also people, personality, direction, industry, relationship, and event information. Learning the stems begins with their basic symbolic images.
1. Jia: Yang Wood, the commander
Jia is Yang Wood and corresponds to due east.
In Qi Men Dun Jia, Jia represents the supreme commander, central figure, or highest-level leader. Because Jia is the most important commander, the system hides it. This is the core meaning of “Dun Jia”—to conceal and protect Jia.
Jia may represent:
- Yang Wood
- Commander or leader
- Due east
- Tall or upright form
- Direct, proud, and self-assured character
Jia Wood resembles a large tree: upright, growing, and authoritative.
2. Yi: Yin Wood, wife and flexible Wood
Yi is Yin Wood and corresponds to the east.
Unlike Jia’s upright strength, Yi is soft, subtle, flexible, and winding. In Qi Men, Yi is one of the Three Wonders and is often used to represent the wife, women, flexible relationships, and mediation.
Yi may represent:
- Yin Wood
- Wife or female figure
- East
- Softness, flexibility, coordination
- Chinese medicine, herbs, and plant-based medicine
Yi Wood resembles vines, flowers, and grasses: soft but able to adapt and connect.
3. Bing: Yang Fire, bright external Fire
Bing is Yang Fire and corresponds to the south.
Bing Fire is visible, bright, warm, and strongly active. In relationship readings, Bing may also represent a male outside interference symbol.
Bing may represent:
- Yang Fire
- South
- Warmth, intensity, openness
- Strong fluctuation
- Brightness, visibility, publicity
- A male external interference symbol in relationship analysis
Bing Fire resembles the sun: bright and outward, but also prone to heat, urgency, and volatility.
4. Ding: Yin Fire, Jade Maiden and subtle Fire
Ding is Yin Fire and corresponds to the south.
Compared with Bing, Ding is more refined, hidden, and subtle. In the course, Ding can represent a female outside interference symbol or the Jade Maiden. It may appear gentle outwardly while carrying careful calculation internally.
Ding may represent:
- Yin Fire
- South
- Jade Maiden or female external interference symbol
- Gentle appearance
- Subtle thinking and strategy
- Lamp fire, candlelight, hidden illumination
Ding Fire resembles a lamp or candle: not as fierce as the sun, yet influential in hidden spaces.
5. Wu: Yang Earth, capital and Heavenly Gate
Wu is Yang Earth and belongs to the center.
Wu Earth is heavy, solid, and forceful. In Qi Men, it is often associated with capital, resources, financial foundation, and the Heavenly Gate.
Wu may represent:
- Yang Earth
- Center
- Solidity, heaviness, force
- Capital, resources, money
- Heavenly Gate
Wu Earth resembles mountains and great land: stable, accumulative, and supportive.
6. Ji: Yin Earth, Earth Door and underground Earth
Ji is Yin Earth and also belongs to the center.
Ji Earth is softer, finer, and more inward than Wu Earth. In the course, Ji represents underground tombs and is associated with the Earth Door.
Ji may represent:
- Yin Earth
- Center
- Calmness, gentleness, inwardness
- Underground space, tombs
- Earth Door
Ji Earth resembles cultivated soil: containing, receiving, storing, and concealing.
7. Geng: Yang Metal, husband and conflict Metal
Geng is Yang Metal and corresponds to the west.
Geng Metal is hard, sharp, angular, and forceful. In Qi Men, Geng is often treated as the greatest threat to Jia Wood because Geng Metal controls Jia Wood. It can represent a husband, but also enemies, pressure, obstacles, and conflict.
Geng may represent:
- Yang Metal
- West
- Husband or male figure
- Enemy, opponent, obstruction
- Tall, sharp, angular form
- Weapons, metal, hard force
In relationship readings, Geng is often an important symbol for the husband or male partner.
8. Xin: Yin Metal, offender and refined Metal
Xin is Yin Metal and corresponds to the west.
Compared with Geng, Xin is more refined, inward, and sharp. In the course, Xin may represent offenders, problematic figures, or people with deep internal calculation.
Xin may represent:
- Yin Metal
- West
- Offender or problematic person
- Squareness, calmness
- Hidden strategy
- Fine metal, jewelry, needles, blades
Xin Metal is less openly forceful than Geng but more refined and hidden.
9. Ren: Yang Water, petty person and flowing Water
Ren is Yang Water and corresponds to the north.
Ren Water is broad, flowing, and highly changeable. The course associates Ren with petty people, logistics, and chemical industry.
Ren may represent:
- Yang Water
- North
- Petty person
- Cunning, movement, change
- Logistics and transportation
- Chemical industry
Ren Water resembles rivers and seas: mobile, hidden, and associated with circulation.
10. Gui: Yin Water, underground Water and fetus
Gui is Yin Water and corresponds to the north.
Gui Water is soft, hidden, and subtle. The course associates Gui with underground water, petroleum, the fetus, and hidden internal thoughts.
Gui may represent:
- Yin Water
- North
- Softness, concealment, subtlety
- Underground water
- Petroleum
- Fetus
- Hidden thoughts or information
Gui Water is deeper and more hidden than Ren Water.
2. Yin and Yang of the Qi Men Stems
In Qi Men Dun Jia, the Ten Stems can be divided into Yang stems and Yin stems.
1. Yang stems: favorable for movement
The course classifies the following five as Yang stems:
Jia, Yi, Bing, Ding, Wu
Their basic tendencies are:
- Favor movement rather than stillness
- Favor the guest rather than the host
- Favor active initiative
- Often produce relatively better results
Here, “guest” can mean the active side, the attacker, or the one who goes out. “Host” can mean the defending side or the one who remains in place.
If a key symbol falls into a Yang stem condition and the overall chart supports action, initiative may be more suitable.
2. Yin stems: favorable for stillness
The course classifies the following five as Yin stems:
Ji, Geng, Xin, Ren, Gui
Their basic tendencies are:
- Favor stillness rather than movement
- Favor the host rather than the guest
- Favor defense, waiting, and observation
- Often bring resistance or less favorable results
This does not mean Yin stems are always bad. It means they are more suitable for stability, concealment, defense, and internal processing. Forced action under a Yin stem condition may meet more resistance.
3. The Five Heavenly Stem Combinations
The Heavenly Stems form five combination relationships:
| Combination | Transformed element | Common interpretation |
|---|---|---|
| Jia-Ji | Earth | Commander combining with Earth Door; an Earth structure |
| Yi-Geng | Metal | Wife and husband; important in relationship readings |
| Bing-Xin | Water | Yang Fire and Yin Metal combine into Water |
| Ding-Ren | Wood | Yin Fire and Yang Water combine into Wood |
| Wu-Gui | Fire | Yang Earth and Yin Water combine into Fire |
Yi-Geng combination in relationship analysis
The Yi-Geng combination is especially important in Qi Men relationship readings.
In the course:
- Yi represents the woman or wife;
- Geng represents the man or husband;
- Yi and Geng combining into Metal is often read as a husband-wife relationship.
Therefore, in relationship matters, one should observe whether Yi and Geng combine, clash, or control each other; whether their palaces generate or control one another; and whether Bing or Ding create external interference.
4. Heavenly Stem Control and Clash
The stems have not only combinations but also control and clash relationships.
1. Seven-Killing control
The course lists the following Seven-Killing controls:
Geng Metal controls Jia Wood
Xin Metal controls Yi Wood
Ren Water controls Bing Fire
Gui Water controls Ding Fire
This is called “Seven Killing” because the two stems are separated by seven positions. This type of control is strong and is used to judge pressure, conflict, restriction, danger, or major obstruction.
Geng controlling Jia is especially important: Jia is the commander, while Geng is the Metal that controls Jia. This is why Qi Men Dun Jia hides Jia from direct exposure.
2. Clash: opposing directions and same-polarity conflict
Heavenly Stem clashes can be understood through direction and polarity.
Their basic features are:
- Directional opposition;
- Same-polarity conflict;
- Yang controls Yang, Yin controls Yin;
- Clash brings movement, change, and instability.
When key stems clash or control one another, it often indicates disagreement, opposing directions, tense relationships, or instability in the matter.
5. Applying Heavenly Stems in a Qi Men Chart
In a Qi Men chart, each palace commonly contains two Heavenly Stems:
- The lower stem is the Earth Plate stem;
- The upper stem is the Heaven Plate stem.
1. Earth Plate stem: what happened in the past
The Earth Plate stem represents the foundation, original chart condition, and past situation. It may be understood as the background or root of the matter.
It is used to observe:
- What has already happened;
- The original foundation of the matter;
- What information a palace originally carries;
- The underlying state of the person or issue.
2. Heaven Plate stem: current state and future direction
The Heaven Plate stem represents the current appearance of the matter and its further development.
It is used to observe:
- How the current situation is changing;
- What appears on the surface;
- What trend may follow;
- Which forces are acting upon the original foundation.
3. Ten Stem Responses
When the Heaven Plate stem and Earth Plate stem meet within the same palace, they produce a specific interaction called a Ten Stem Response.
Ten Stem Responses are important in practical Qi Men interpretation. They help explain:
- How the current state acts upon the past foundation;
- How events in a palace develop;
- How relationships between people change;
- Whether a matter proceeds smoothly or meets obstruction, conflict, or change.
6. Key Stems in Relationship Readings
In relationship readings, Heavenly Stem symbolism is especially useful. The course highlights the following symbols:
| Symbol | Relationship image |
|---|---|
| Yi Wonder | Wife, woman |
| Geng Metal | Husband, man |
| Bing Wonder | Male outside interference |
| Ding Wonder | Female outside interference |
| Six Harmony | Marriage, relationship, bonding factor |
1. Yi and Geng: the main marital line
Yi-Geng combination is one of the core relationship patterns.
If Yi and Geng combine or generate each other, and their palaces are in good condition, the relationship may have connection, interaction, and conditions for formation.
If Yi and Geng clash, control each other, fall into emptiness, become constrained, or enter a tomb, the relationship may involve barriers, pressure, misunderstanding, or difficulty materializing.
2. Bing and Ding: external interference
Bing and Ding are often used to observe external interference in relationship matters:
- Bing can represent male external interference;
- Ding can represent female external interference.
If Bing or Ding forms strong combinations, clashes, controls, or punishments with Yi or Geng, one may need to examine whether there are external relationships, hidden emotions, competitors, or ambiguous factors.
3. Six Harmony: whether the relationship can bind
Six Harmony represents union, cooperation, and the bonding factor in relationships.
In relationship analysis, one should not only examine Yi and Geng, but also the palace of Six Harmony: whether it has strength, whether it is controlled or empty, and how it relates to Yi and Geng.
7. Summary
This lesson introduced the basic use of the Heavenly Stems in Qi Men Dun Jia:
- Jia is Yang Wood and the commander, the central figure that Qi Men hides and protects.
- Yi is Yin Wood, representing the wife, flexible coordination, and plant or herbal symbolism.
- Bing is Yang Fire, intense and volatile, and can represent male external interference.
- Ding is Yin Fire, subtle and gentle outwardly, and can represent the Jade Maiden or female external interference.
- Wu is Yang Earth, representing capital, resources, and the Heavenly Gate.
- Ji is Yin Earth, representing calmness, underground space, tombs, and the Earth Door.
- Geng is Yang Metal, representing husband, opponent, pressure, and sharp conflict.
- Xin is Yin Metal, representing offenders, hidden calculation, refinement, and concealed problems.
- Ren is Yang Water, representing petty people, logistics, chemical industry, and flow.
- Gui is Yin Water, representing underground water, petroleum, fetus, and hidden information.
- Yang stems favor movement and guest; Yin stems favor stillness and host.
- The Yi-Geng combination is frequently used in relationship analysis.
- Heaven Plate stems represent current and future conditions, while Earth Plate stems represent past and foundation. Their meeting forms Ten Stem Responses.
Once the stem images are understood, later study of Ten Stem Responses, Eight Gates, Nine Stars, and Eight Spirits becomes much more concrete and practical.
