Find your kua
The kua year turns at Li Chun (around Feb 4), not January 1: births before Li Chun count as the previous year. The tool handles this automatically and shows the exact boundary moment.
How to use it (folk framework)
- · Bed: folk practice points the head of the bed toward your Tian Yi (Heavenly Doctor) or Yan Nian (Longevity) direction — for a sense of rest and harmony.
- · Desk: folk practice sits with the back to an inauspicious direction and faces Sheng Qi (Life Breath) or Yan Nian.
- · Door & circulation: keep lucky sectors bright and well-used; keep unlucky sectors quiet and little-lingered-in.
- · If the layout cannot change, tradition simply says “use the good sectors more, the bad ones less.” This is a cultural frame of reference, not a rule — no anxiety required.
What is a kua number?
The kua (ming gua) number is the personal direction system of the Eight Mansions school of feng shui: a birth year plus gender yields a number from 1 to 9, mapped to a trigram. The numbers split into two groups — the East group (1, 3, 4, 9), lucky toward North, South, East and Southeast, and the West group (2, 6, 7, 8), lucky toward West, Northwest, Southwest and Northeast.
Each kua carries a “wandering year” direction table: four auspicious stars — Sheng Qi (vitality), Tian Yi (rest), Yan Nian (harmony), Fu Wei (stability) — and four inauspicious ones — Jue Ming, Wu Gui, Liu Sha, Huo Hai. Tradition orients beds, desks and doors accordingly. The system is folk housing culture handed down from Ming-Qing Yangzhai practice; we label it honestly and promise nothing.
In Plain Words
Three things to remember: birthday + gender → one kua number; kua numbers come in East and West groups, each with four lucky directions; and January-to-early-February babies count under the previous year — the boundary is Li Chun, not New Year’s Day and not Chinese New Year (the tool already handled it). Treat directions as a free experiment: turning a bed costs nothing, and sleeping easy is what matters.
Feng shui is traditional Chinese spatial culture and folklore: kua numbers, flying stars, and Tai Sui notes are folk sayings. They neither predict nor guarantee wealth, health, relationships, or any life outcome, and they are not medical, financial, or safety advice.
FAQ
What is a kua number?
A kua number is your personal index in Eight Mansions feng shui: computed from birth year and gender, it lands on 1–9 and maps to a trigram. Tradition uses it to pick which directions “fit” you for beds, desks and doors. It is folk housing culture, not precision prediction.
What is the difference between the East and West groups?
The eight kua split in two: the East group (Kan 1, Zhen 3, Xun 4, Li 9) is lucky toward North, South, East and Southeast; the West group (Kun 2, Qian 6, Dui 7, Gen 8) is lucky toward West, Northwest, Southwest and Northeast. Kua within one group share lucky directions — one reason folk matchmaking compares kua numbers.
I was born in January — which year do I use?
The kua year turns at Li Chun (around February 4) — not at January 1 and not at Chinese New Year. Births from January 1 until the Li Chun moment chart under the previous year: someone born on January 20, 1990 is charted under 1989. Our tool decides day by day with a calendar library; if you were born on the Li Chun day itself, the exact solar-term time decides (shown in your result).
Why is there no kua number 5?
In the Lo Shu square, 5 occupies the center, and the center has no trigram. Tradition resolves this by “lodging” the 5: a male kua of 5 becomes 2 (Kun), a female kua of 5 becomes 8 (Gen). Final kua numbers are therefore always 1, 2, 3, 4, 6, 7, 8 or 9.
