In Zi Wei Dou Shu, the Heavenly Stems and Earthly Branches are the "language" of the entire system — just as you must know the English alphabet before you can read English, you must understand the Heavenly Stems and Earthly Branches before you can read a chart. From my teaching experience, many people learning Zi Wei Dou Shu skip over the Heavenly Stems and Earthly Branches and rush straight to stars and palaces, only to become completely stuck when they reach the four transformations and major cycles. Because the foundation of those advanced techniques lies entirely in the Heavenly Stems and Earthly Branches. Spend 30 minutes reading this article thoroughly and you will save yourself dozens of hours of fumbling later.
The Basic Framework of Heavenly Stems and Earthly Branches
In Zi Wei Dou Shu, Heavenly Stems and Earthly Branches are the foundational charting language..
The Heavenly Stems and Earthly Branches are the ancient Chinese system for recording time and also the foundational language of Zi Wei Dou Shu. There are 10 Heavenly Stems (Jia Yi Bing Ding Wu Ji Geng Xin Ren Gui) and 12 Earthly Branches (Zi Chou Yin Mao Chen Si Wu Wei Shen You Xu Hai). The Heavenly Stems and Earthly Branches are paired according to fixed rules, forming 60 non-repeating combinations called the "Sixty Jia-Zi," constituting one complete time cycle.
Yin-Yang Classification of Heavenly Stems and Earthly Branches
Every Heavenly Stem and Earthly Branch has a yin-yang attribute, which is very important in chart construction. Those born in Yang years are Yang-destined and major cycles progress forward. Those born in Yin years are Yin-destined and major cycles progress in reverse. Therefore, the yin-yang of the Heavenly Stem directly determines the direction of your major cycles.
- Yang Stems: Jia, Bing, Wu, Geng, Ren — the odd-numbered positions in sequence
- Yin Stems: Yi, Ding, Ji, Xin, Gui — the even-numbered positions in sequence
- Yang Branches: Zi, Yin, Chen, Wu, Shen, Xu — likewise the odd-numbered positions
- Yin Branches: Chou, Mao, Si, Wei, You, Hai — the even-numbered positions
The Ten Heavenly Stems: Quality Markers of Time
The most critical function of the Ten Heavenly Stems in Zi Wei Dou Shu is "triggering the four transformations." Each Heavenly Stem corresponds to a set of four-transformation stars (Hua Lu, Hua Quan, Hua Ke, Hua Ji), so with different Heavenly Stems, the same star manifests completely differently Regarding fortune and misfortune.

The Twelve Earthly Branches: The Coordinate System of Space
The Twelve Earthly Branches have two core functions in Zi Wei Dou Shu: first, they constitute the 12 palaces of the chart (each Earthly Branch corresponds to a fixed position); second, through the relationships of combination, clash, and gathering among Earthly Branches, they reveal the hidden connections between palaces.

Chen, Xu, Chou. Wei are all Earth among the four Earthly Branches and are called the "Four Tomb Storehouses." The Chen palace is called "Heaven Net" and the Xu palace is called "Earth Web." In the chart, those with the Life Palace in Chen, Xu, Chou, or Wei tend to have more introverted and steady personalities, but may also appear stubborn and conservative. From my observations, those with Life Palaces in the Four Tomb Storehouse palaces usually have very strong accumulative ability. Whether in wealth, knowledge, or connections, they tend to accumulate slowly rather than explode all at once.
Six Combinations, Six Clashes, and Three-Gathering Formations
The Earthly Branches are not independent of one another — they have complex interaction relationships among themselves. The three most important relationships in Zi Wei Dou Shu are the six combinations, six clashes, and three-gathering formations.
Six Harmonious Earthly Branch Combinations
The six combinations are 6 pairs of "harmonious" Earthly Branch combinations, representing natural cooperative tendencies between two palaces:
- Zi-Chou combine ; Yin-Hai combine ; Mao-Xu combine
- Chen-You combine ; Si-Shen combine ; Wu-Wei combine (Sun-Moon combination)
The meaning of six combinations in the chart is: the life domains represented by these two palaces have a natural tendency to support each other. For example. If The Life Palace is in Zi and the Parents Palace is in Chou, Zi-Chou combining means there is a natural affinity between the chart holder and their parents.
Six Clashing Earthly Branch Combinations
The six clashes are 6 pairs of directly opposing Earthly Branch relationships, representing collision and tension between energies. In the chart, the opposite palace is in a six-clash relationship:
- Zi-Wu clash. chou-Wei clash. yin-Shen clash
- Mao-You clash. chen-Xu clash. si-Hai clash
Earthly Branch Three-Gathering Formations
Three-gathering formations are triangular combinations formed by 3 Earthly Branches, representing the convergence of the same five-element energy. This is the origin of the "triple alliance" in charts:
- Fire Formation: Yin-Wu-Xu (Yin as long life, Wu as peak, Xu as tomb)
- Water Formation: Shen-Zi-Chen (Shen as long life, Zi as peak, Chen as tomb)
- Metal Formation: Si-You-Chou (Si as long life, You as peak, Chou as tomb)
- Wood Formation: Hai-Mao-Wei (Hai as long life, Mao as peak, Wei as tomb)
The "triple" in "triple-four alignment" comes from the three-gathering formation — the 3 palaces in the same three-gathering formation mutually influence each other's stars. Therefore, understanding the three-gathering formation is understanding the mathematical foundation of triple-four alignment. For a deeper understanding of triple-four alignment applications, refer to the Complete Triple-Four Alignment Guide.
The Practical Role of Heavenly Stems and Earthly Branches in Chart Analysis
After understanding the basic concepts, the next step is to see what roles the Heavenly Stems and Earthly Branches play in actual chart analysis. This is the key step from "knowledge" to "technique."
Three Key Practical Functions of Heavenly Stems
Birth-Year Stem Triggers Original Four Transformations
The Heavenly Stem of your birth year determines the original four transformations in your chart. For example, for those born in a Jia year, the four transformations are Lian Zhen Hua Lu, Po Jun Hua Quan, Wu Qu Hua Ke, and Tai Yang Hua Ji. Which palace these transformation stars fall in directly influences your lifelong pattern.
Palace Stem Triggers Major Cycle Four Transformations
Every palace has its own Heavenly Stem. When You enter a major cycle, the Heavenly Stem of that major cycle's Life Palace triggers a new set of four transformations layered on top of the original. Therefore, the four-transformation changes in each decade are determined by the palace stem.
Annual Stem Triggers Annual Four Transformations
The Heavenly Stem of the current year determines the annual four transformations. The original four transformations + the major cycle four transformations + the annual four transformations layered together constitute the complete fortune map for a particular year.
Three Key Practical Functions of Earthly Branches
- Defining palace positions: the 12 palaces in the chart each occupy one Earthly Branch palace — the five element and yin-yang of the Earthly Branch influences the "baseline tone" of the palace.
- Defining triple-four alignment: through the three-gathering formation combinations, determining the triple-four alignment relationship of each palace.
- Defining annual cycle movement: the annual Earthly Branch determines the position of the annual Life Palace (the annual Earthly Branch is the Earthly Branch where the annual Life Palace is located), thereby determining the redistribution of the annual twelve palaces.

The Sixty Jia-Zi and the Nayin System
With 10 Heavenly Stems and 12 Earthly Branches, paired according to the rule of "yang pairs with yang, yin pairs with yin," 60 non-repeating combinations are formed (not 120), called the Sixty Jia-Zi. Each combination has a "Nayin" five-element attribute, which is the basis for determining the five-element cycle.
The Basic Principle of Nayin
Nayin is a method of "synthesizing the five-element energies of Heavenly Stems and Earthly Branches into a new five element." Every two Jia-Zi combinations share one Nayin. For example, both Jia-Zi and Yi-Chou are "Gold in the Sea." The names of Nayin carry imagery (Gold in the Sea, Fire in the Furnace, Wood in the Great Forest, etc. ), reflecting the energy characteristics of that five element in a specific state.
Nayin Quick-Reference Mnemonic
The ancients summarized a set of Nayin quick-reference mnemonics to aid memorization:
- Jia-Yi: Gold-Water-Fire
- Bing-Ding: Water-Fire-Earth
- Wu-Ji: Fire-Earth-Wood
- Geng-Xin: Earth-Wood-Gold
- Ren-Gui: Wood-Gold-Water
For those who wish to study destiny analysis systematically, foundational knowledge requires long-term memory and understanding.

FAQ Q&A
Frequently Asked Questions
The Heavenly Stems represent the energy and time quality of Heaven, and their most critical role is to determine the triggering of the Four Transformations Stars. The earthly branches represent positions in space, and the 12 houses in the natal chart correspond to the 12 earthly branches. Use the starnum ranking tool to directly see the configuration of the heavenly stems and earthly branches in your birth chart.
Liuhe is a harmonious pairing of 6 groups (Zichou, Yinhai, Maoxu, Chenyou, Sishen, Wuwei), which represents the fusion of energy. Six Chongs are 6 groups of oppositions (Ziwu, Chouwei, Yinshen, Maoyou, Chenxu, Sihai), representing energy collisions. In the natal chart, the interaction between the opposite houses is the manifestation of the Six Oppositions.
The four modernizations are completely determined by the heavenly stems. Nian Qian determines the four transformations of the original game, Daxian Gong Qian determines the four transformations of Daxian, and Fleeting Nian Qian determines the four transformations of Fleeting Years. The same star may turn into fortune or bad luck due to different heavenly stems. Therefore, the heavenly stems are the only triggers of the four transformations.
No need to memorize it. Modern layout tools calculate this automatically. But understanding the principle of Nayin will help deepen your understanding of the Five Elements Game. It is recommended to master the five elements and yin and yang of the heavenly stems and earthly branches first, and then gradually get into contact with them after the foundation is solid.
Bringing It Together
The Heavenly Stems and Earthly Branches are the foundational language of Zi Wei Dou Shu — just as the English alphabet is to English: without knowing the alphabet you cannot read. Heavenly Stems govern the quality of time, triggering the four transformations. The most powerful variable in the chart. Earthly Branches govern spatial position, defining the coordinates of the palaces and the interaction relationships of triple-four alignment. Understanding the Heavenly Stems and Earthly Branches gives you the foundational ability to read any chart technique. Many people consider the Heavenly Stems and Earthly Branches "too basic" and skip them, but the solidity of one's foundation creates an ever-widening gap at later stages. To see how the Heavenly Stems and Earthly Branches work in your chart, visit the starnum chart tool to view the complete chart.
