What Kua 1 means
In the Eight Mansions (Ba Zhai) school of feng shui, Kua 1 is one of the nine personal kua numbers. Kua 1 belongs to the East group, which also includes kua 3, 4 and 9. In the tradition, Kua 1 is linked with the water element and the Kan trigram (which also names the bagua’s career area in the north), and its personal “life palace” is in the north.
The method uses your birth year and gender to give you a personal set of directions. These are a traditional guide for choosing where to sit, sleep or work. They are not a prediction of what will happen to you.
Check that you are Kua 1
To find your kua number, reduce your birth year to a single digit and apply the formula for your gender. For people born before 2000, men subtract the result from 10 and women add 5. For people born in 2000 or later, men subtract from 9 and women add 6. If the result is 5, men become kua 2 and women become kua 8.
Two examples that give Kua 1:
- A man born in 1981: 8 + 1 = 9, then 10 − 9 = 1. Kua 1.
- A woman born in 1986: 8 + 6 = 14, then 1 + 4 = 5. Then 5 + 5 = 10, then 1 + 0 = 1. Kua 1.
The Chinese solar year starts around 3 to 5 February, not on 1 January. If your birthday falls in early February, check the exact date for your birth year before you use the formula. The full kua number calculation walks through the steps and the edge cases.
Your four favourable directions
Kua 1 has four favourable sectors:
- Southeast: Sheng Chi (growth and prosperity). This is the strongest of the four. Traditionally, use it for work, study and important decisions when you can.
- East: Tian Yi (health and recovery). Traditionally a good sector for rest and recuperation.
- South: Yan Nian (relationships and longevity). Linked with family and close relationships.
- North: Fu Wei (stability and personal growth). Traditionally a good sector for focused study and calm thinking.
Your four unfavourable directions
The other four sectors are the unfavourable ones for Kua 1:
- Southwest: Jue Ming (total loss). The most serious sector in the chart. Avoid facing it or sleeping with your head toward it.
- West: Huo Hai (mishaps and disputes). Avoid spending long periods working or sleeping here.
- Northeast: Wu Gui (five ghosts). Traditionally linked with gossip and misfortune.
- Northwest: Liu Sha (six killings). Traditionally linked with setbacks and disagreements.
Using Kua 1 directions at home
- Sleep. Where the room allows, place the bed so your head points toward a favourable sector, such as Southeast or East. Keep your head away from the Southwest.
- Desk and study. Face a favourable direction when you work or study. Southeast suits important work, and North suits focused study.
- Entrance. If your home has more than one door, use the one in a favourable sector when you can.
- Kitchen and bathroom. The Eight Mansions tradition places these rooms (see kitchen feng shui for the stove itself) in the unfavourable sectors, where they are said to reduce the effect of those sectors. Keep them out of the favourable ones.
- Use this as a guide, not a rule. The room layout, the orientation of the house and other people’s kua numbers all affect the picture. When two people in a home have different favourable sectors, many practitioners suggest a compromise.
Colours and materials for the water element
Blue and black are the traditional colours for the water element, so they suit Kua 1 well. White and grey, which are metal tones, support water in the five-element cycle. Shades of brown and other earth tones are usually avoided by Kua 1, because earth is said to control water.
A few blue or black accents in a bedroom or office are a simple way to bring in the element without repainting a room.
Traditional personality traits of Kua 1
Traditional descriptions of Kua 1 people often mention a practical, reserved nature and a good listener who observes before acting. They are described as flexible when a change is useful, and as thoughtful about the future. Many sources also describe them as good communicators and mediators.
These are traditional descriptions, not scientific findings. Use them as a starting point for thinking about yourself or someone you know, not as a verdict.
Kua 1 compatibility with other kua numbers
Compatibility in the Eight Mansions tradition is usually explained through the five-element cycle:
- Kua 1 with Kua 1: both are water, so they are generally seen as harmonious.
- Kua 3 and 4 (wood): water feeds wood, so Kua 1 is often seen as supporting them.
- Kua 6 and 7 (metal): metal feeds water, so the support flows toward Kua 1.
- Kua 2 and 8 (earth): earth controls water, so this pairing is often described as harder work. See the Kua 2 and 8 guide for those numbers.
- Kua 9 (fire): water controls fire, so the result depends on balance. Read the Kua 9 guide for more on that number.
