Introduction to the 24 Mountain Directions System and the Position of Wei Mountain
The 24 mountain directions system is a core foundation of geographical feng shui, used to determine the precise orientation of houses, graves, and architectural structures. Unlike the simple 8-direction system (Ba Zhai) that divides the compass into 8 equal parts of 45 degrees each, the 24 mountain system divides the compass into 24 parts of 15 degrees each. This granularity allows feng shui practitioners to analyze more subtly the influence of geomagnetic fields and qi fields on living spaces.
In the 24 mountains, each mountain is named according to one of three symbol systems: Heavenly Stems (Jia, Yi, Bing, Ding, Geng, Xin, Ren, Gui), Earthly Branches (Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, Hai), and the Eight Trigrams (Qian, Kun, Xun, Gen). Wei Mountain belongs to the Earthly Branch group, located precisely from 202.5 to 217.5 degrees on the feng shui compass, measured clockwise from North (0 degrees). The center of Wei Mountain lies at 210 degrees, corresponding to the Xin Wei palace in the 60 Jiazi cycle.
Geographically, Wei Mountain is in the southwest corner of the compass, between Ding Mountain (south-southwest) and Kun Mountain (west-southwest). In relation to other mountains, Wei Mountain directly opposes Chou Mountain (located in the northeast, from 22.5 to 37.5 degrees). This opposition creates an important energy axis, influencing interpretation when Wei Mountain appears in a structure.
Basic Attributes of Wei Mountain
Five Elements and Trigram
Wei Mountain belongs to the Earth element, specifically Yin Earth. In five element theory, Earth represents stability, center, nurturing ability, and support. Earth is the origin of all things, the mother of Metal, and the place where all things return after their cycle ends. Thus, Wei Mountain carries the energy of accumulation, preservation, and transformation.
Wei Mountain is associated with the Kun trigram (☷), a purely yin trigram symbolizing mother earth, receptivity, nurturing, and tolerance. The Kun trigram in the I Ching is described as "The earth's condition is receptive; the noble person uses thick virtue to carry all things." This indicates that Wei Mountain relates to maternal qualities, patience, tolerance, and endurance.
Relationships with Other Factors
In the Stem-Branch system, Wei is the 8th of the 12 Earthly Branches, belonging to the Three Harmony group with Hai and Mao (the Wood group). This creates a special connection: although Wei is Earth, it is in the Wood trio, so combining with Hai and Mao forms a Wood situation, carrying energy of growth and development. Meanwhile, Wei clashes with Chou (the 2nd branch), and Chou is also Earth. Two Earths clashing can create stagnation and blockage if not resolved.
Directionally, Wei Mountain belongs to the Kun palace of the Later Heaven Bagua. The Kun palace in the later heaven arrangement is in the southwest, corresponding to the 7th and 8th lunar months (early autumn), when yin qi begins to rise after the yang peak of summer. Therefore, Wei Mountain is linked to transitional periods, harvest time, and preparation for rest.
How to Determine and Apply Wei Mountain in Practice
Measurement and Determination
To determine if a structure is on Wei Mountain, a precise feng shui compass (luo pan) is used. Measurement should be taken at the center of the house, avoiding magnetic objects like phones, watches, and large metal frames. When the compass needle points between 202.5 and 217.5 degrees, the structure is identified as Wei Mountain.
However, feng shui typically considers both mountain and facing. The mountain is the direction behind the house (the backing), and the facing is the direction in front. A house "sitting Wei facing Chou" means the back is in the Wei direction (southwest), and the front faces Chou (northeast). Conversely, "sitting Chou facing Wei" means the back is northeast and the front faces southwest.
Distinguishing Wei Mountain from Adjacent Mountains
Wei Mountain is often confused with Kun Mountain (217.5 to 232.5 degrees) and Ding Mountain (187.5 to 202.5 degrees). The boundaries between these mountains are narrow, only 15 degrees, so small measurement errors can lead to misidentification. In practice, if the house center is slightly toward Kun Mountain, the layout and interpretation differ completely from Wei Mountain. This complexity explains the saying "a tiny error leads to a mile of difference," emphasizing the importance of accurate measurement.
Feng Shui Significance of Wei Mountain in Different Schools
Ba Zhai School (Life Trigrams)
In Ba Zhai, Wei Mountain belongs to the Kun palace, one of the Four West Houses (West group: Qian, Kun, Gen, Dui). According to this school, a house sitting Wei or facing Wei is in the West group, suitable for people with West group life trigrams (Kun, Qian, Gen, Dui in Ba Zhai Ming Jing). Specifically, individuals with a Kun life trigram (often those with gua number 2) are considered compatible with a house sitting Wei facing Chou.
However, Ba Zhai does not only consider the mountain but also the eight main directions. For a house facing Wei (i.e., looking southwest), good and bad positions are determined based on the sitting mountain. Auspicious directions include Sheng Qi, Tian Yi, Yan Nian, Fu Wei; inauspicious ones include Jue Ming, Wu Gui, Liu Sha, Huo Hai, calculated from the sitting mountain's position.
Xuan Kong Fei Xing School (Flying Stars)
In Xuan Kong, Wei Mountain is interpreted based on period luck and the combination of mountain stars and facing stars. Each period (20 years) has a governing star, and Wei Mountain receives different stars across periods. For example, in Period 8 (2004-2023), Wei Mountain receives star 3 (San Bi, Wood) as mountain star and star 2 (Er Hei, Earth) as facing star in certain combinations. The combination of Wood star 3 and Earth star 2 can create Wood overcoming Earth, requiring careful analysis.
Xuan Kong practitioners examine Wei Mountain in relation to current and future period luck. Since Wei Mountain is Earth, when it encounters Fire stars (star 9 Zi Wei, star 7 Po Jun in some cases), it is supported; when it meets Wood stars (stars 3 and 4), it is controlled. Additionally, whether each star is flourishing or declining must be considered for accurate interpretation.
Luan Tou School (Forms)
In Luan Tou, Wei Mountain belongs to the gentle type of Earth mountains, favoring rounded hills, flat land, and yellow or brown colors. If behind the house (sitting Wei) there is a moderately high mountain or structure shaped like a recumbent qilin or elephant, it is considered good. Conversely, jagged rocky mountains, steep terrain, or fierce-looking objects are unfavorable for this mountain.
For facing Wei (looking southwest), the water-facing area should have water (rivers, lakes, roads) but not too rapid or torrential. Water meeting Earth mountains needs to be gentle and meandering, symbolizing gradual wealth accumulation. If water is too strong and rushes straight at the house, it may cause loss and difficulty retaining wealth.
Mountain-Facing Combinations Involving Wei Mountain
Sitting Wei Facing Chou
This is the most common combination for Wei Mountain. A house sitting Wei facing Chou has its back to the southwest and faces northeast. In feng shui, this combination belongs to the West group and is often interpreted as having stability in foundation, suitable for families seeking durability and longevity. However, since Chou and Wei clash, special attention is needed to resolve this conflict by creating a curved or shielding layout or using appropriate feng shui remedies.
Sitting Chou Facing Wei
Conversely, a house sitting Chou facing Wei has its back to the northeast and faces southwest. The Wei facing in this combination receives qi from the southwest, home of the Kun trigram. Qi from this direction is yin, gentle, and harmonious, benefiting family relationships and careers in education, caregiving, and the arts. However, the quality of water in front must be assessed to determine overall auspiciousness.
Other Combinations in the 120 Fen Jin
In the 120 fen jin system (dividing each mountain into 5 fen jin of 3 degrees each), Wei Mountain has 5 fen jin: Yi Wei (Metal), Ding Wei (Water), Ji Wei (Fire), Xin Wei (Earth), and Gui Wei (Wood). Each fen jin carries a different element, creating variations in interpretation. Among these, Xin Wei is often considered the most prosperous because pure Earth matches the mountain's inherent qi, while Ji Wei (Fire) generates Earth but requires consideration of Fire's strength in each period.
Practical Applications When Encountering Wei Mountain
Choosing a House Direction
When evaluating land or a house on Wei Mountain, one does not simply consider Wei Mountain alone but also the overall factors: sitting mountain, facing, water outlet, dragon vein, and period luck. Since Wei Mountain is Earth, those with Fire destiny (because Fire generates Earth) or Earth destiny are often considered most compatible. Those with Wood destiny should be cautious because Wood overcomes Earth, potentially hindering the positive energy of this mountain.
Interior Arrangement
For houses on Wei Mountain, the southwest area (Kun palace) should be emphasized. This area represents maternal love, the woman of the household, and care. It should be kept clean and airy, with Fire element items (lamps, candles, red or orange colors) to generate Earth, or Earth element items (ceramics, brown or earthy crystals) to strengthen energy. Avoid placing too many plants (Wood) or Wood element objects here, as Wood overcomes Earth, causing weakness.
Time and Period Considerations
According to feng shui, each mountain direction has prosperous and declining years. Wei Mountain is in a three-harmony group with Hai and Mao, so Hai, Mao, and Wei years are often considered more favorable for structures on Wei Mountain. Conversely, Chou years (clashing with Wei) and years with overly strong Wood may be disadvantageous. However, these interpretations are relative and depend heavily on the specific context of each house, land, and family.
Conclusion
Wei Mountain is one of the most meaningful directions in the 24 mountain system. With Earth element, Kun trigram, and southwest location, it symbolizes stability, nurturing, and steady accumulation. However, interpreting Wei Mountain cannot be isolated from the overall context: its combination with the opposing Chou mountain, relationships with adjacent mountains, period luck over time, and especially the specific forms of the house and land. Feng shui is a complex knowledge system requiring comprehensive and careful consideration, avoiding hasty conclusions based on a single factor. Practitioners should combine multiple schools and methods, and most importantly, maintain an open yet discerning mindset, not letting superstitious interpretations dominate important life decisions.
