Chapter 6 of 50
基础知识
The previous chapter organized static knowledge of the Heavenly Stems and Earthly Branches—concepts, Yin-Yang and Five Elements attributes, directions, time, zodiac animals, Na Jia (cycle-matching) —which serve as the foundation for BaZi (Eight Characters) study. However, static attributes alone cannot truly capture the interaction and circulation of Five Elements forces within a BaZi chart. This chapter enters the realm of dynamic stem-branch relationships, covering nine major types: Generation (Sheng), Control (Ke), Punishment (Xing), Clash (Chong), Combination (He), Harm (Hai/Chuan), Breach (Po), Assembly (Hui), and Tomb/Storehouse (Mu).
These dynamic relationships are core tools for later analysis of a chart's favorable and unfavorable elements, as well as for assessing fortune in annual and major luck periods. Beginners are advised to memorize them repeatedly until fully internalized.
Generation and Control concepts derive directly from Five Elements generation and control theory. Each Heavenly Stem and Earthly Branch possesses its own Five Elements attribute, so generation and control relationships exist naturally between stems and branches. Generation means nourishment, support, and promotion; Control means restraint, regulation, and limitation.
Can Heavenly Stems and Earthly Branches generate or control each other?
The answer is: Yes, they can—and indeed, they must.
Some argue that Heavenly Stems can only interact with other Heavenly Stems, and Earthly Branches only with other Earthly Branches—that no generation or control relationship exists between stems and branches, reasoning that "Heaven and Earth cannot generate or control one another." This view is grandstanding and self-limiting, and should be decisively rejected. The Heavenly Stems represent Heaven, the Earthly Branches represent Earth, and the qi of Heaven and Earth naturally interpenetrates and responds to each other. The generation and control between stems and branches is precisely the manifestation of the cosmic qi flow between Heaven and Earth. If stems and branches were artificially separated, BaZi metaphysics would lose its most fundamental dynamic foundation.
Metal generates Water → Water generates Wood → Wood generates Fire → Fire generates Earth → Earth generates Metal
Mutual generation among the Five Elements forms an endless cycle—the basic mode of energy transformation in nature.
| Generator (Stems/Branches) | Generated (Stems/Branches) | Five Elements Flow |
|---|---|---|
| Geng Xin Shen You | Ren Gui Hai Zi | Metal generates Water 🌊 |
| Ren Gui Hai Zi | Jia Yi Yin Mao | Water generates Wood 🌱 |
| Jia Yi Yin Mao | Bing Ding Si Wu | Wood generates Fire 🔥 |
| Bing Ding Si Wu | Wu Ji Chen Xu Chou Wei | Fire generates Earth ⛰ |
| Wu Ji Chen Xu Chou Wei | Geng Xin Shen You | Earth generates Metal 💎 |
Example: Geng Xin Shen You generate Ren Gui Hai Zi—meaning Geng can generate any one of Ren, Gui, Hai, or Zi. The same logic applies to all other cases. Each specific stem or branch can exert a "generating" effect on the corresponding stems or branches in the row below.
Metal controls Wood → Wood controls Earth → Earth controls Water → Water controls Fire → Fire controls Metal
| Controller (Stems/Branches) | Controlled (Stems/Branches) | Five Elements Flow |
|---|---|---|
| Geng Xin Shen You | Jia Yi Yin Mao | Metal controls Wood 🌲 |
| Jia Yi Yin Mao | Wu Ji Chen Xu Chou Wei | Wood controls Earth ⛰ |
| Wu Ji Chen Xu Chou Wei | Ren Gui Hai Zi | Earth controls Water 🌊 |
| Ren Gui Hai Zi | Bing Ding Si Wu | Water controls Fire 🔥 |
| Bing Ding Si Wu | Geng Xin Shen You | Fire controls Metal 💎 |
Special Note: Among these, Xu, Chen, Chou, and Wei are Tomb/Storehouse Earth (墓库之土). Their controlling effect on Water cannot be simplistically treated as ordinary "control"; this will be explained in dedicated later articles. The "control" exerted by Tomb/Storehouse Earth carries characteristics of collection, absorption, and confinement, rather than purely dominant suppression.
Heavenly Stem Combinations involve pairwise bonding relationships totaling five groups, which upon combining transform into new Five Elements attributes.
| Stem Combination | Transformation Result |
|---|---|
| Jia–Ji Combination | Transforms to Earth ⛰ |
| Yi–Geng Combination | Transforms to Metal 💎 |
| Bing–Xin Combination | Transforms to Water 🌊 |
| Ding–Ren Combination | Transforms to Wood 🌱 |
| Wu–Gui Combination | Transforms to Fire 🔥 |
Stem Combination can be understood as deep collaboration and transformation between two differing forces. For instance, when Jia Wood meets Ji Earth, Wood's upward growing energy combined with Earth's carrying and containing capacity ultimately settles into the stability of "Earth." In modern interpersonal terms, this resembles two people with starkly different personalities going into business together and, after磨合, forming a new organizational culture.
Earthly Branch Combinations comprise Six Harmonies (Liu He) and Three Harmonies (San He) —the two levels of the strongest "affinity" relationships among earthly branches.
| Pairing | Six Harmony |
|---|---|
| Zi–Chou Combination | Water and Earth combine |
| Yin–Hai Combination | Wood and Water combine |
| Mao–Xu Combination | Wood and Earth combine |
| Chen–You Combination | Earth and Metal combine |
| Si–Shen Combination | Fire and Metal combine |
| Wu–Wei Combination | Fire and Earth combine |
Six Harmonies resemble the mutual attraction of Yin and Yang—tightly coordinated pairing, like interlocking gears in perfect mesh.
Three Harmony occurs when three earthly branches jointly form a powerful Five Elements bureau (方局), whose strength far exceeds that of Six Harmony.
| Triple Combination | Resulting Bureau |
|---|---|
| Yin–Wu–Xu | Three Harmony Fire Bureau 🔥 |
| Si–You–Chou | Three Harmony Metal Bureau 💎 |
| Shen–Zi–Chen | Three Harmony Water Bureau 🌊 |
| Hai–Mao–Wei | Three Harmony Wood Bureau 🌱 |
A Three Harmony bureau can be likened to team operations: Yin is Fire's growth phase (ignition), Wu is Fire's imperial peak (blazing flames), and Xu is Fire's tomb/storehouse position (lingering warmth). The three occupy distinct stages of Fire's lifecycle, and when combined, form a complete energy chain of Fire—from generation to climax to convergence. In a chart, once a Three Harmony bureau is established, it typically indicates that the corresponding Five Elements force is extraordinarily dominant, enough to sway the overall direction of the entire chart.
Clash (Chong) signifies opposition, conflict, and collision—the frontal confrontation among earthly branch relationships.
| Six Clash Pairings | Directional Opposition |
|---|---|
| Zi–Wu Clash | North-South opposition; Water and Fire battle 🔥🌊 |
| Chou–Wei Clash | Two Earth collide; Yin-Yang mutual excitation ⛰ |
| Yin–Shen Clash | Wood and Metal battle; East-West standoff 🌱💎 |
| Mao–You Clash | Wood and Metal clash; facing gates 🌲💎 |
| Chen–Xu Clash | Two Earth collide; Heaven's Net and Earth's Snare ⛰ |
| Si–Hai Clash | Fire and Water clash; extreme South and North 🔥🌊 |
A Six Clash is akin to two vehicles hurtling toward each other head-on—the conflict is fierce, and energy releases rapidly. In a chart, clashing often signifies change, turbulence, and instability, yet it may also present opportunities to dismantle the old and establish the new. Clash is not purely "inauspicious"; the key lies in what gets destroyed—clashing away an unfavorable element brings good fortune, while clashing away a favorable element is detrimental.
Harm (Hai), also called Chuan (Pierce), represents a relationship of covert injury and mutual obstruction—more concealed and harder to detect than Clash.
| Six Harm Pairings | Relationship Characteristics |
|---|---|
| Zi–Wei Harm | Water covertly damaged by Earth 🌊⛰ |
| Chou–Wu Harm | Damp Earth dims Fire ⛰🔥 |
| Yin–Si Harm | Wood and Fire consume each other 🌱🔥 |
| Mao–Chen Harm | Wood and Earth undermine each other 🌲⛰ |
| Shen–Hai Harm | Metal and Water draw from each other 💎🌊 |
| You–Xu Harm | Metal and Earth obscure each other 💎⛰ |
If Clash is an overt conflict, then Harm is conducting covert sabotage. It does not confront directly but rather drains, erodes, and undermines from behind the scenes. In interpersonal relationships, Harm resembles "outward harmony with inward discord"—all appears pleasant on the surface while each side tearsthe other down underneath. Individuals whose charts contain Harm often encounter underhanded opposition or subtle interpersonal attrition, making it vital to consciously establish healthy boundaries.
Punishment (Xing) represents penalty, injury, and torment—one of the more complex and structurally negative forces among earthly branch relationships.
| Type | Combinations | Explanation |
|---|---|---|
| Rudeness Punishment | Zi–Mao Xing | Zi Water and Mao Wood: mother-child punishment |
| Arrogance Punishment | Yin–Si–Shen Three Xing | All three punish one another, no sequence |
| Ingratitude Punishment | Chou–Xu–Wei Three Xing | All three punish one another, no sequence |
| Self-Punishment | Chen, Wu, You, Hai | Chen with Chen, Wu with Wu, You with You, Hai with Hai |
Punishments have no directional sequence:
The essence of Punishment is structural contradiction within a system. Self-punishment is like a person who sets their own limits and endlessly saps their own energy internally; Three Punishment resembles team members constantly hindering each other—each capable of harming another without a fixed direction. Those with Punishment in their charts often face tangled, hard-to-resolve issues concerning health, interpersonal relations, or legal matters. The watchword here is "internal friction."
Breach (Po) signifies destruction, damage, and disintegration. Its force is relatively mild but characterized by an "undermining" quality.
| Breach Pairings | Relationship Characteristics |
|---|---|
| Zi–You Breach | Water leaks Metal's qi 🌊💎 |
| Yin–Hai Breach | Water soaks Wood's roots 🌊🌱 |
| Mao–Wu Breach | Fire scorches Wood's leaves 🔥🌲 |
| Chen–Chou Breach | Earth damages Earth ⛰ |
| Si–Shen Breach | Fire destroys Metal 🔥💎 |
| Wei–Xu Breach | Earth spoils Earth ⛰ |
The effect of Breach is weaker than Clash or Punishment, but it often manifests as a state of intact appearance with underlying damage. For instance, Yin–Hai are in Six Harmony, yet simultaneously in a Breach relationship—much like business partners who appear tightly aligned on the surface but actually erode each other's foundation progressively during cooperation. When a chart carries Breach, one should stay alert to "silent attrition" in the details.
Three Assembly (San Hui) occurs when three directionally adjacent earthly branches converge into a powerful directional force. The Five Elements energy represented by Three Assembly is the strongest aggregate of any configuration in the entire earthly branch system.
| Assembly Combination | Formed Directional Bureau | Direction |
|---|---|---|
| Yin–Mao–Chen | Three Assembly Eastern Wood | East 🌱 |
| Si–Wu–Wei | Three Assembly Southern Fire | South 🔥 |
| Shen–You–Xu | Three Assembly Western Metal | West 💎 |
| Hai–Zi–Chou | Three Assembly Northern Water | North 🌊 |
The difference between Three Assembly and Three Harmony: Three Harmony is an "alliance" across directions, while Three Assembly is a "convergence" within one direction. Yin, Mao, and Chen all belong to the East; once combined, Eastern Wood qi reaches its extreme—like the Yangtze River flowing into the ocean, its force is vast and unmatched. In BaZi analysis, when a Three Assembly bureau forms, it typically indicates that a particular Five Elements force is overwhelmingly dominant and can almost single-handedly determine the overall direction of the entire chart.
Tombs/Storehouses (Mu Ku) are the distinctive functions of four Earthly Branch Earth positions: Chen, Xu, Chou, and Wei. They serve both as carriers of Earth and as "warehouses" or "final resting places" for the other five elements.
| Tomb/Storehouse | Element Treasured/Entombed |
|---|---|
| Chen | Water and Earth Storehouse/Tomb 🌊⛰ |
| Xu | Fire and Earth Storehouse/Tomb 🔥⛰ |
| Chou | Metal Storehouse/Tomb 💎 |
| Wei | Wood Storehouse/Tomb 🌱 |
"Tomb" and "Storehouse" are fundamentally two sides of the same coin: when a Five Elements force possesses vitality, its tomb/storehouse acts as a "warehouse"—collecting and nurturing its strength. When that element lacks vitality, the tomb/storehouse becomes its "grave"—ushering it toward decay and decline. For example, Chen is Water's tomb/storehouse. If Water is strong in a chart, Chen acts as a water reservoir, holding resources for future use. If Water is weak, however, Chen may become the grave that buries Water. Detailed applications of Tombs/Storehouses will be explored in depth in later articles.
| Relationship Type | Nature of Action | Power Level | Core Characteristics |
|---|---|---|---|
| Generation (生) | Nourishment, Support | Gentle & Continuous | Giving and transferring energy 🌱 |
| Control (克) | Restraint, Regulation | Medium-strong | Suppression and management of energy ⚔️ |
| Heavenly Stem Combination (天干合) | Cooperative Transformation | Medium | Two elements combine to form a new Five Element 🤝 |
| Earthly Branch Six Harmony (地支六合) | Close Affinity | Medium-strong | Mutual attraction, strong compatibility 💞 |
| Earthly Branch Triple Harmony (地支三合) | Powerful Alliance | Strong | Three parties converge into a powerful Five Element configuration 🔺 |
| Earthly Branch Six Clash (地支六冲) | Direct Confrontation | Strong | Opposition and collision, drastic changes 💥 |
| Earthly Branch Six Harm (地支六害) | Covert Harm | Weak → Medium | Hidden depletion, underhanded sabotage 🕳 |
| Earthly Branch Punishment (地支相刑) | Torment & Internal Drain | Medium → Strong | Structural contradictions, self-harm or mutual harm ⚡ |
| Earthly Branch Breach (地支相破) | Minor Disruption | Weak | Invisible erosion, inconsistency between appearance and reality 🔧 |
| Earthly Branch Three Convergence (地支三会) | Directional Unification | Strongest | Convergence of same direction, overwhelming force 🌊 |
| Tomb/Vault (墓库) | Storage/Destiny | Depends on strength | Warehouse or tomb of the Five Elements 🏛 |
The dynamic relationships outlined above are the core grammar of BaZi (Eight Characters) study. For beginners, it is recommended to consolidate your understanding by following this path repeatedly:
The next section will delve into the specific application rules of these dynamic relationships, methods for determining auspicious or inauspicious outcomes, and their practical roles in BaZi structural analysis.
