There are 9 gua numbers in 8 mansions feng shui.
And because the number 5 is a neutral number, people who are deemed to have the gua number 5 are assigned the attributes similar to gua number 2 or 8 depending on whether the individual is male or female.
The gua number, or Ming Gua (命卦) is a simple astrological concept that profiles a person so that feng shui can be customized to suit the personal feng shui of the subject in question.
This Ming Gua can sometimes also be referred to as the life star or life gua.
Gua 8 is associated with the Gen trigram ☶ which is traditionally meant to convey the characteristics of young energetic men.

Yet even though one might have a personal gua of Gen in 8 mansions feng shui, actual feng shui practice can often result in a different trigram sector within a house that represents the resident.
This is because a house has it’s own energy map which is different from a person’s personal aura.
So don’t be confused when a feng shui masters states that you are represented by another Gua such as Li, but you know that your personal gua in 8 mansions is Gen.
Attributes Of Gua 8
In Ba Zhai feng shui, gua 8 is associated with the earth element.
Unlike gua 2 which is represented by earth in the form of soil, gua 8 is represented by hard solid earth such as rocks, boulders and mountains.
This implies that gua 8 personalities are calm, resolute, and in a way, immovable.
They can be depended upon when the card are down and called on when there is chaos.
This is in part due to strong principles that they believe in. Changing their minds on positions can be as rare as rare earth itself.
Even when gua 8 personalities are erratic, the persona they present still creates the perception of calmness in the minds of the people around them. This is a natural ability of gua 8.
In conflict gua 6 people prefer to back away from confrontation rather than take the bull by it’s horns.
However, this does not men defeat. They would prefer to quietly plan and execute their responses without declaring them.
A drawback of such personalities is that they can often keep so much of their true feelings inside that they implode.
You don’t have to face the world yourself. Opening up to the people around you who cares can be a great outlet of expression that leads to a more balanced life.
Basic feng shui
Ba Zhai feng shui states that there are 4 auspicious and 4 inauspicious directions with each gua number.
The directions for gua 8 which belongs to the west group are as follows.
| Gua | SQ | TY | YN | FW | 5G | 6K | HH | JM |
| 8 | SW | NW | W | NE | N | E | S | SE |
With the above energy types mapped out, it can then be possible to do space planning by locating lively areas in the house in the favorable sectors.
For example, Sheng Qi is widely regarded as the most prosperous directions in terms of wealth, business success and career progression. As such work areas, study rooms, or living rooms will be suited to be located in the SQ sectors.
When that is not possible due to space restrictions and limitations, then facing the directions when seated will be a great alternative.
For example, a work desk that enables you to face the SQ direction when seated would be good.
By the same line of thought, the Yan Nian direction is a good sector for harmony and the luck of a healthy and active social life. It would be suited for family areas like the living room and dining room.
It must be noted at this point that these are personal 8 mansions directions.
Conducting 8 mansions assessment and implementation on a house might come up with different findings.
Personal grand duke
Since a pattern can be identified with the sequence of how gua numbers are identified from referencing the gender and year of birth of an individual, the zodiac of particular groups of gua 8 can also be determined.
This allows for the zodiac of a person to be revealed. Which indicates where the personal grand duke is.
This is generally an unlucky area for an individual to conduct important activities in.
The following table illustrates the location of the personal grand dukes according to gua and year of birth.

| 1930,1966,2002 | S2 | N2 |
| 1939,1975,2011 | E2 | W2 |
Both the personal grand duke and clash sector of a house are negative areas to the person in question.
Fixtures and furniture like the sofa and bed should avoid these areas as much as possible.
The good thing is that these are specific 15° segments. Not the entire 45° of each cardinal and ordinal directional sectors.
