Feng Shui Numbers & Kua
Feng shui uses numbers in three distinct ways, and most confusion comes from mixing them up. There are the numbers on your house — your address, your apartment number, the digits on your front door. There is your Kua number — your personal direction number calculated from your birth year. And there are the symbolic numbers of the Bagua and Five Elements — the 8 trigrams, the 5 elements, the 9 stars. These three number systems do different things, answer different questions, and are calculated di
Feng Shui House Numbers: What Actually Matters
A feng shui and numbers house assessment starts with a reality check: the number on your door affects the energy of your house less than the direction the door faces, less than what you see when you open it, and less than whether the door opens fully without obstruction. If you're worried about your house number but haven't checked these three things, you're working in the wrong order.
That said, feng shui numbers house interpretation follows a simple method: reduce the house number to a single digit by adding the digits together, then interpret the result. House number 247: 2+4+7=13, 1+3=4. The house is a 4 house. Each digit 1-9 has a meaning: 1 (new beginnings, independence), 2 (partnership, balance), 3 (creativity, expression), 4 (stability, foundations — but note that in Chinese the word for 4 sounds like the word for death, making it culturally sensitive), 5 (change, movement), 6 (nurturing, responsibility), 7 (reflection, analysis), 8 (abundance, prosperity — considered the most auspicious number in Chinese culture), 9 (completion, fulfillment).
For feng shui and numbers, the interpretation is gentle: 8 is encouraging, 4 requires cultural awareness but is not inherently problematic, and any number's effect is mild compared to the structural feng shui factors. An 8 house with the front door facing a T-junction has a more significant challenge than a 4 house with ideal form. For feng shui home number concerns, treat the number as a minor influence, not a primary factor.
The feng shui house number that matters more: whether your house number is clearly visible from the street. An invisible or missing house number means qi has trouble finding your front door — a literal issue, not a numerological one.
Kua Number: Personal Direction That Actually Affects You
Your feng shui kua number \(命卦, ming gua\) is the most personally useful number in feng shui numbers practice, determining which directions support you individually. It determines which feng shui and numbers house directions are most favorable — which way your bed should face, which way your desk should face, and which entrance directions work best for you.
The Kua number is calculated from your birth year using the Eight Mansions formula. For males born before 2000: sum the last two digits of your birth year, reduce to a single digit, subtract from 10. Example: 1985 → 8+5=13 → 1+3=4 → 10-4=6. Kua 6, West Group. For females: sum the last two digits, reduce, add 5. Example: 1992 → 9+2=11 → 1+1=2 → 2+5=7. Kua 7, West Group.
The feng shui numbers that matter for personal direction: Kua 1, 3, 4, 9 are East Group — favorable directions are east, southeast, south, north. Kua 2, 6, 7, 8 are West Group — favorable directions are west, northwest, southwest, northeast. Kua 5 males convert to Kua 2; Kua 5 females convert to Kua 8.
Your four favorable feng shui directions (in priority order): Sheng Qi (best overall — bed and desk facing), Tian Yi (health — sleep facing when recovering), Yan Nian (relationships — bed facing for partnership priority), Fu Wei (stability — desk facing for calm focus). Your four unfavorable: Huo Hai (minor obstacles), Wu Gui (quarrels), Liu Sha (relationship strain), Jue Ming (most unfavorable — avoid for bed and desk facing).
Bagua and Lucky Numbers
The feng shui lucky numbers in the Bagua system are the eight trigram numbers: 1 (Kan, Water, north), 2 (Kun, Earth, southwest), 3 (Zhen, Wood, east), 4 (Xun, Wood, southeast), 6 (Qian, Metal, northwest), 7 (Dui, Metal, west), 8 (Gen, Earth, northeast), 9 (Li, Fire, south). These numbers appear in Flying Star charts and Bagua references. They are system identifiers, not personal lucky numbers — a 9 in your Flying Star chart means the Fire star is in that sector, not that the sector is "lucky number 9."
The cultural feng shui and numbers context: 8 (ba, 八) sounds like prosperity (fa, 发) and is the most culturally favored number. 9 (jiu, 九) sounds like longevity (jiu, 久) and is considered complete. 6 (liu, 六) sounds like smooth/flowing (liu, 流) and is favorable for career. 4 (si, 四) sounds like death (si, 死) and is avoided in Chinese culture — many buildings skip the 4th floor, similar to Western buildings skipping the 13th floor. These cultural associations are separate from the technical feng shui use of the same numbers.
Your feng shui kua number is the most personally impactful of all feng shui numbers. The feng shui numbers that shape your daily experience are not your house number — they are your four favorable Kua directions. Understanding feng shui and numbers means knowing the difference between house numerology (mild influence) and Kua directions (direct impact on bed and desk orientation). For feng shui numbers house concerns, the feng shui kua number matters far more than the digits on your door. A professional feng shui house number assessment puts the emphasis where it belongs: on personal directions, not on door digits.

Take the second-best favorable direction that faces open space. Spatial reality always overrides personal direction. Facing Sheng Qi into a wall is worse than facing Tian Yi into an open room. Your feng shui directions from Kua are preferences; the room's physical constraints are non-negotiable.
Yes. When partners have different favorable directions (e.g., one East Group, one West Group), orient the bed to support the person with the greater health or sleep priority. An angle that's 15-20 degrees off ideal for the second person is acceptable. The bed orientation is a compromise, not a competition. For couples with different feng shui numbers, the bed orientation should prioritize the person with greater health or sleep sensitivity.
