Twenty-Four Mountains and Directions: A Complete Feng Shui Guide
What Are the Twenty-Four Mountains?
The Twenty-Four Mountains (二十四山) is a precise directional system used in Feng Shui to divide the 360-degree circle into 24 equal segments of 15 degrees each. It forms the most essential ring on the Luopan (Feng Shui Compass) and serves as the foundational tool for Setting Direction and orienting buildings.
Cultural Context: While a Western compass shows only the four cardinal directions (N, S, E, W), the Luopan contains dozens of concentric rings with metaphysical information. The Twenty-Four Mountains is the outermost directional ring that Feng Shui masters consult first — it provides the precision needed to align a home with auspicious cosmic energies.
The Twenty-Four Mountains is composed of Eight Heavenly Stems, Twelve Earthly Branches, and Four Trigrams:
- Eight Heavenly Stems: Jia (甲), Yi (乙), Bing (丙), Ding (丁), Geng (庚), Xin (辛), Ren (壬), Gui (癸) — Wu (戊) and Ji (己) occupy the center and are not used
- Twelve Earthly Branches: Zi (子), Chou (丑), Yin (寅), Mao (卯), Chen (辰), Si (巳), Wu (午), Wei (未), Shen (申), You (酉), Xu (戌), Hai (亥)
- Four Trigrams: Qian (乾), Gen (艮), Xun (巽), Kun (坤) — representing the four inter-cardinal directions
Composition of the Twenty-Four Mountains
Four Cardinal Directions (4 Mountains)
The Four Cardinal Directions correspond to the four main orientations, each represented by its primary Earthly Branch:
| Direction | Mountain | Degree Range | Five Elements |
|---|---|---|---|
| North | Zi (子) | 352.5°–7.5° | Water |
| East | Mao (卯) | 82.5°–97.5° | Wood |
| South | Wu (午) | 172.5°–187.5° | Fire |
| West | You (酉) | 262.5°–277.5° | Metal |
Four Inter-cardinal Directions (4 Mountains)
The Four Inter-cardinal Directions represent the diagonal orientations, expressed through four Trigrams:
| Direction | Mountain | Degree Range | Five Elements |
|---|---|---|---|
| Northwest | Qian (乾) | 307.5°–322.5° | Metal |
| Northeast | Gen (艮) | 37.5°–52.5° | Earth |
| Southeast | Xun (巽) | 127.5°–142.5° | Wood |
| Southwest | Kun (坤) | 217.5°–232.5° | Earth |
Eight Heavenly Stems Positions (8 Mountains)
The Eight Heavenly Stems fill the spaces between the cardinal and inter-cardinal positions:
| Direction | Mountain | Degree Range | Five Elements |
|---|---|---|---|
| North-East | Gui (癸) | 7.5°–22.5° | Water |
| NE by N | Chou (丑) | 22.5°–37.5° | Earth |
| NE by E | Yin (寅) | 52.5°–67.5° | Wood |
| East by N | Jia (甲) | 67.5°–82.5° | Wood |
| East by S | Yi (乙) | 97.5°–112.5° | Wood |
| SE by E | Chen (辰) | 112.5°–127.5° | Earth |
| SE by S | Si (巳) | 142.5°–157.5° | Fire |
| South by E | Bing (丙) | 157.5°–172.5° | Fire |
| South by W | Ding (丁) | 187.5°–202.5° | Fire |
| SW by S | Wei (未) | 202.5°–217.5° | Earth |
| SW by W | Shen (申) | 232.5°–247.5° | Metal |
| West by S | Geng (庚) | 247.5°–262.5° | Metal |
| West by N | Xin (辛) | 277.5°–292.5° | Metal |
| NW by W | Xu (戌) | 292.5°–307.5° | Earth |
| NW by N | Hai (亥) | 322.5°–337.5° | Water |
| North by W | Ren (壬) | 337.5°–352.5° | Water |

Relationship Between Twenty-Four Mountains and Eight Mansions
In Eight Mansions Feng Shui, the Twenty-Four Mountains correspond to the Bagua (Eight Trigrams) as follows:
| Trigram Position | Mountains Included |
|---|---|
| Kan (坎) (North) | Ren (壬), Zi (子), Gui (癸) |
| Gen (艮) (Northeast) | Chou (丑), Gen (艮), Yin (寅) |
| Zhen (震) (East) | Jia (甲), Mao (卯), Yi (乙) |
| Xun (巽) (Southeast) | Chen (辰), Xun (巽), Si (巳) |
| Li (离) (South) | Bing (丙), Wu (午), Ding (丁) |
| Kun (坤) (Southwest) | Wei (未), Kun (坤), Shen (申) |
| Dui (兑) (West) | Geng (庚), You (酉), Xin (辛) |
| Qian (乾) (Northwest) | Xu (戌), Qian (乾), Hai (亥) |
Each Trigram governs three Mountains — a principle known as "One Trigram Governs Three Mountains" (一卦管三山).
Twenty-Four Mountains and Yin and Yang
Yin and Yang of the Earthly Branches
| Yang Branches | Zi (子), Yin (寅), Chen (辰), Wu (午), Shen (申), Xu (戌) |
|---|---|
| Yin Branches | Chou (丑), Mao (卯), Si (巳), Wei (未), You (酉), Hai (亥) |
Yin and Yang of the Heavenly Stems
| Yang Stems | Jia (甲), Bing (丙), Geng (庚), Ren (壬) |
|---|---|
| Yin Stems | Yi (乙), Ding (丁), Xin (辛), Gui (癸) |
Yin and Yang of the Four Trigrams
| Yang Trigrams | Qian (乾), Gen (艮) |
|---|---|
| Yin Trigrams | Kun (坤), Xun (巽) |
Cultural Context: Yin and Yang (阴阳) is the foundational duality in Chinese cosmology — Yang represents active, bright, expansive energy, while Yin represents receptive, calm, contracting energy. In Feng Shui, every mountain, direction, and element carries a Yin or Yang quality that must be balanced for harmony and prosperity.
Applications of the Twenty-Four Mountains in Feng Shui
Setting Direction and Orientation
When a Feng Shui master uses the Luopan (Feng Shui Compass) to determine a building's orientation, the reading is precise down to a specific Mountain within the Twenty-Four system. For example:
- "Sitting Zi, Facing Wu" (坐子向午): Sitting North, Facing South — aligned precisely with due north
- "Sitting Ren, Facing Bing" (坐壬向丙): Sitting North-East, Facing South-West — a slight deviation from true north
- "Sitting Gui, Facing Ding" (坐癸向丁): Sitting North-West by North, Facing South-East — another nuanced alignment
Fen Jin (Gold Division) Precision
While each Mountain spans 15 degrees, practical Feng Shui applications require even finer precision:
- Each Mountain is divided into 5 sub-segments of 3 degrees each, called "Fen Jin" (分金, Gold Division)
- This creates 120 Fen Jin divisions total, corresponding to the "One Hundred Twenty Dragons" (一百二十龙)
- Masters select the most auspicious Fen Jin degree when Setting Direction for maximum positive energy
Inclined Direction (兼向)
When a building's orientation does not fall at the exact center of a Mountain but drifts toward a neighboring Mountain, this is called an Inclined Direction (兼向, jian xiang). Examples include:
- "Zi Mountain, Wu Direction, Inclined to Ren and Bing" (子山午向兼壬丙): The sitting position drifts toward the Ren side of the Zi Mountain
- "Zi Mountain, Wu Direction, Inclined to Gui and Ding" (子山午向兼癸丁): The sitting position drifts toward the Gui side of the Zi Mountain
Auspicious Date and Time Selection
When selecting auspicious dates for important events, practitioners consider the relationship between the day's Heavenly Stems and Earthly Branches and the Twenty-Four Mountains — avoiding clashes that could disrupt the property's energy.
Quick Tips: Working with the Twenty-Four Mountains
Quick Tips:
- Always verify your home's facing direction with a Luopan (Feng Shui Compass), not just a smartphone compass — smartphones are accurate only to about 5 degrees
- Even a 3-degree deviation from your intended Mountain can shift you into a completely different energy sector
- If you're hiring a Feng Shui consultant, ask them to identify both your Sitting Mountain and Facing Mountain precisely — this is the foundation of all subsequent analysis
Twenty-Four Mountains Memorization Mnemonic
Eight Stems, Four Trigrams, Twelve Branches — the Twenty-Four Mountains to keep in heart.
Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, Hai arranged complete.
Jia, Yi, Bing, Ding, Geng, Xin, Ren — Gui pairs with the Four Corners Qian, Kun, Gen, Xun.
Each Trigram governs three Mountains — the Luopan's directional teaching is true transmission.
"Without mastering the Twenty-Four Mountains, one cannot speak of Feng Shui's subtle brilliance." (不明二十四山，难谈风水之精妙) The Twenty-Four Mountains is the core tool for Setting Direction in Feng Shui — whether you are assessing a Yang Dwelling (living home) or Yin Dwelling (ancestral grave), precise command of this system is absolutely essential.
How to Apply the Twenty-Four Mountains in Your Home
- Measure your facing direction precisely: Stand at the center of your home with a Luopan and identify which Mountain your front door faces (this becomes your "Facing Mountain")
- Determine your sitting direction: The opposite side of your home (where your back wall is) becomes your "Sitting Mountain"
- Look up your Five Elements: Check the table above to discover which element governs your home's orientation
- Enhance with matching elements: Decorate or place objects in the corresponding element's colors and materials to harmonize with your home's energy
- Consult a master for Inclined Directions: If your home doesn't sit perfectly on one Mountain, professional guidance ensures you select the right Fen Jin
