Why Numbers Matter in Feng Shui
In Feng Shui and Chinese culture, numbers are far more than mathematical symbols — they carry vibrational energy that can attract or repel good fortune. This belief stems from the phonetic similarities between numbers and meaningful words in Chinese, a concept known as homophones. Understanding lucky and unlucky numbers allows you to make strategic choices about your home address, phone number, wedding date, business name, and more.
The Luckiest Numbers in Feng Shui
Number 8 — Wealth and Infinity
The number 8 is the most auspicious number in Chinese culture and Feng Shui. Its pronunciation “bā” sounds like “fā,” meaning prosperity and wealth. Visually, 8 mirrors the infinity symbol, suggesting endless abundance. The 2008 Beijing Olympics deliberately started on 08/08/08 at 8:08 PM — a testament to 8's power. Use 8 in: house numbers, phone numbers, business addresses, and pricing.
Number 6 — Heaven's Luck
Six represents luck from the heavens, smooth progress, and the support of helpful people. “Liù” sounds like “liú,” meaning to flow smoothly. Six is particularly powerful for career advancement, mentorship, and receiving blessings. A combination of 6-8 (68) is considered especially fortunate for business.
Number 9 — Longevity and Completion
Nine is the highest single digit and represents completeness, longevity, and imperial power. “Jiǔ” sounds like the word for long-lasting. It is excellent for relationships, lasting success, and spiritual growth. The number 99 symbolizes a long and happy marriage, which is why many Chinese couples choose dates with 9s for weddings.
Number 1 — New Beginnings
One represents new beginnings, independence, and leadership. It is associated with water energy and career opportunities. While not as celebrated as 8, 1 carries the energy of starting fresh and standing out as a leader. Ideal for launching new projects or businesses.
Number 3 — Growth and Creativity
Three represents growth, vitality, and living energy. Associated with the wood element, 3 brings creative energy and expansive thinking. It is especially supportive for artistic endeavors, family growth, and health improvement.

Numbers to Avoid in Feng Shui
Number 4 — The Most Unlucky
The number 4 is considered the most inauspicious in Chinese culture because “sì” sounds like “sǐ,” the word for death. Many buildings in China and Asia skip the 4th floor entirely. Combinations like 14 (“want to die”), 24 (“easy to die”), and 44 (“die die”) are particularly avoided. If your address contains 4, place a Feng Shui cure such as a bagua mirror or wind chimes near the entrance.
Number 5 — Instability
Five represents the Yellow Star 5 in Flying Star Feng Shui, which is associated with misfortune, illness, and obstacles. While 5 has some positive associations (the five elements), in numerology it often indicates instability and change. If the number 5 dominates your address, use metal element cures like six-rod metal wind chimes.
Number 7 — Decreasing Luck
In the current Period 9 (2024-2043), the number 7 has lost much of its positive energy. While it was very auspicious in Period 7 (1984-2003), it now carries declining energy. Avoid relying heavily on 7 for important decisions in this period.

How to Apply Lucky Numbers in Your Home
House and Apartment Numbers
Your address number influences the energy of your entire home. If your address contains unlucky numbers, there are several remedies: Add auspicious numbers to make a favorable sum (e.g., house number 4 + apartment 4 = 8 together), display your address in a lucky color (gold or red), or place a bagua mirror or wind chimes at the entrance.
Phone Numbers and Car Plates
Choose phone numbers and license plates with as many 8s, 6s, and 9s as possible. Avoid sequences with multiple 4s. In Hong Kong and Singapore, auspicious car plate numbers are auctioned for hundreds of thousands of dollars — a testament to the cultural significance of lucky numbers.
Feng Shui Number Placement at Home
Display meaningful numbers throughout your home: place 8 coins in the wealth corner, use decorative items in groups of 6 or 9, choose curtains or tiles in patterns of 3, 6, 8, or 9. Avoid decorating with groups of 4 objects.
Your Kua Number — Personal Lucky Number
Your Kua number is your most personal lucky number in Feng Shui, calculated from your birth year and gender. It determines your lucky directions, auspicious rooms, and favorable timing. For men, subtract the last two digits of your birth year from 10. For women, add 5 to the last two digits. This gives you a number from 1-9 (excluding 5) that governs your personal energy.
