Xuan Kong Flying Star feng shui or Xuan Kong Fei Xing is a discipline in Feng Shui, and is an integration of the principles of Yin Yang, the interactions between the five elements, the eight trigrams, the Lo Shu numbers, and the 24 Mountains, by using time, space and objects to create an astrological chart to analyze positive auras and negative auras of a building.
These include analyzing wealth, mental and physiological states, success, relationships with external parties, and health of the inhabitant.
During the Qing Dynasty, it was popularized by grandmaster Shen Zhu Ren, with his book Mr. Shen's Study of Xuan Kong, or Shen Shi Xuan Kong Xue.
Flying Star Feng Shui does not limit itself to buildings for the living or Yang Zhai, where rules pertaining to directions equally apply to all built structures; it also applies to grave sites and buildings for spirits or Yin Zhai.
Fundamentals
Numbers
In the Lo Shu Square, flying stars are nine numbers.
Each number in the Lo Shu represents one of the Chinese Trigrams and is related to an Element, Family Member, Cardinal, Colour, Hour, Season, Organ, Ailment and many others.
The numbers always move to the lower right (northwest), middle right (west), lower left (northeast), upper center (south), lower center (north), upper right (southwest), middle left (east), upper left (southeast) and back to the center.
Time
Time is divided into 20-Year cycles. Each cycle of 20 years is a Period or "Yun". A grand cycle comprises 9 Periods in total, which covers a span of 180 years.
Periods are used to describe the cyclical pattern of Qi. Different types of Qi have different strengths and weaknesses with the reference to a particular Period.
Periodic Table on Flying Stars
Timely and Untimely Flying Stars
A timely star is positive for a building whereas an untimely star is negative. For the current period, Period 8 (Year 2004–2023), stars Eight, Nine and One are timely (For a building, they are timely if and only if the object placed in that palace is timely). Star Eight is most timely which is often treated as Prosperous and Noble Star. Star Nine and Star One belong to Sheng Qi, a growing energy. The other six stars are regarded as having retreating, killing or dead qi.
Space
An accurate measurement of direction must be obtained before any system of Feng Shui can be undertaken.
A Luopan is a magnetic compass to determine the precise direction of a structure or an item.
24 Mountains
The most important ring on the Luopan is the 24 Mountain ring.
On the 24 Mountain ring, each direction is subdivided into three sectors.
Taking Directions
Using the principles of Yin and Yang, the facing of a building is determined by the side of the built structure that receives most Yang Qi.
A house is constructed with an architectural frontage with its side that faces whatever landscape feature. The facing of that house is considered by the direction of its frontage which is most Yang in nature.
In apartments, or condominiums, the facing of a unit is determined by the facing of the entire building. If the structure is not an obvious facade, the facing of the unit is determined by the side of the building having the most Yang energy (faces the busiest crowd flow).
Taking locations
Energy in a building can be tapped into by locating a person within a sector that houses the energy. Ideally, living objects should be located in a sector with positive Qi as determined by Flying Star Chart.
The layout of a building is demarcated with a Nine Palace grid, which looks like a tic-tac-toe grid. A door, room or other object's location refers to the square within this grid where the object is found. This may or may not correspond to the direction that the object faces. A door could be located in the southwest sector, but face south. Its location could be also southwest, and its direction to be facing to the south.
Objects
Objects are essential to evaluate the Feng Shui of a building.
Mountain
Mountain generates Qi. A lush and green mountain or hill generates auspicious Qi, while a barren, rocky rising area will, in general, generate inauspicious energy.
In urban areas, skyscrapers, apartments or any structure that rises from the ground have a similar role to a mountain: generating energy outside. From inside, cupboards, wardrobes, or any furniture that is taller or larger than any others nearby are also considered mountains.
