A Complete Study of Commercial Shop Fengshui (Esoteric Edition): From Form School and the Luopan to Xuankong Dating
A systematic account of commercial shop fengshui built on the traditional arts themselves — exterior form school (luantou), the Twenty-Four Mountains, Three Cycles Xuankong plotting, doors/paths/registers, annual date selection, Five Phases remediation, and worked case studies.
XVII. The Three Basic Charts of Xuankong Flying Star
1. The Period Chart: The Skeleton of the Time's Qi
Once a given period has been determined, the period star is entered into the center palace and flown out to the eight directions along the Luo Writing's track, forming the period chart (yunpan). For the Ninth Period, Nine enters the center, and the stars are then flown out in sequence. The period chart represents the basic distribution of that period's qi, and serves as the foundation from which the mountain-star and facing-star charts are started. Looking at the period chart alone tells one only the skeleton — it cannot by itself judge whether the wealth star sits at the door.
The Luo Writing's track for the Nine Palaces generally runs from the center to the northwest, west, northeast, south, north, southwest, east, and southeast, and then returns to the center to form a cycle; any number exceeding nine wraps back around to one. Learners should draw out an empty set of Nine Palaces by hand many times over, to make sure the direction is never mirrored by mistake. A floor plan commonly places north at the top, while a traditional Luo Writing diagram sometimes places south at the top — the drawing convention must be fixed first before proceeding.
2. The Mountain-Star Chart: The Sitting Direction and Still, Solid Qi
Taking the period chart's number at the palace of the sitting mountain and entering it into the center, then deciding forward or reverse flight according to the Three-Cycle Dragon and yin-yang of that sitting mountain, produces the mountain-star chart (shanpan). The mountain stars are used to observe personnel, stability, health, support, and static functions. A so-called "flourishing mountain" requires the currently governing mountain star to fall at the sitting direction or its corresponding palace, and for the exterior form to have a mountain, something solid, something elevated, and something still to receive it.
Even though a commercial shop places heavy weight on wealth, it cannot afford to ignore the mountain star. Staff stability, the proprietor's decision-making, and the continuity of the product and service all need a still, solid space. The solid support behind the register, the office's main seat, and a stable back area are all commonly linked to putting the mountain star to use. If the flourishing mountain star falls on an empty doorway, a light well, or a fast-moving corridor, this is a mismatch of form and qi in the pattern known as "the mountain star descending into water" — one cannot call it auspicious on the strength of the number alone.
3. The Facing-Star Chart: The Facing Direction and Flowing, Transactional Qi
Taking the period chart's number at the palace of the facing point and entering it into the center, then flying it forward or in reverse according to the Three-Cycle Dragon and yin-yang of the facing mountain, produces the facing-star chart (xiangpan). The facing stars weigh wealth, customer flow, transactions, dissemination, and dynamic opportunity. A flourishing facing star is best met with a door, a path, water, low ground, and openness — called "the water star finding water"; if the flourishing facing star instead falls against a sealed high wall, a huge tall cabinet, or a still back storeroom, it becomes hard for it to take effect.
The facing star is not only about what is directly in front of the shop. Once flown out, every palace has its own facing star, and a side door, an escalator, an interior passage, or a spot with moving water can all activate whichever palace they fall in. The fine-grained work of commercial layout is to overlay each palace's facing star with the actual active points one by one, rather than asking only whether the main door's facing is auspicious.
4. How the Three Charts Are Written Together in Each Palace
Each palace normally records three numbers together: the period star, the mountain star, and the facing star. To avoid confusion, one can fix a convention — mountain star upper-left, facing star upper-right, period star below or at the center — and note this convention in the legend. Different charting software uses different layouts, and transcribing between them is where mountain and facing are most easily swapped by mistake. A report should include at least one labeled Nine-Palace diagram, and keep the original degree readings on record.
When judging a palace, look first at the two stars — mountain and facing — then at the background period star; first distinguish whether the main use is movement or stillness, then look at the Five Phases' generation and control; then overlay the exterior form, the door and path, and the annual star. If a palace serves as the register, the facing star and the form carry more weight, though the mountain star's relations still affect its user; if it serves as an office's main seat, the mountain star and its support carry more weight, and the facing star should not be strongly activated with water there.
5. Checking Forward Flight Against Reverse Flight
Forward or reverse flight is not decided by a simple rule like "sitting north flies forward, sitting south flies in reverse." One must first know which trigram the period chart's number at the sitting or facing palace corresponds to, then take the actual sitting or facing mountain's position within the Heaven, Earth, or Human Three-Cycle Dragon, and decide forward or reverse according to the yin-yang of the corresponding mountain within that cycle-dragon. The safest method for a beginner is to use a checked table of the Twenty-Four Mountains' yin-yang, and cross-verify against a known standard chart.
If the sitting-facing falls on a slant line, a substitute trigram may be involved, and the stars would then be started differently. In that case, do not calculate it in your head and simply hand over a conclusion — write out every step: which number the given period puts at the sitting palace, which trigram it corresponds to, which mountain of which cycle-dragon is taken, whether it is yin or yang, and therefore whether it flies forward or in reverse. The facing-star chart follows the same logic. Being independently recomputable matters more than any air of mystery.
6. The Basic Five Phases of the Nine Flying-Star Numbers
One White belongs to Water, Two Black to Earth, Three Jade to Wood, Four Green to Wood, Five Yellow to Earth, Six White to Metal, Seven Red to Metal, Eight White to Earth, Nine Purple to Fire. The color names are traditional labels; the core substance is the numbered star and its Five Phases quality. Each star also carries its own trigram, human affairs, and object imagery, but for a commercial judgment it is enough to grasp first the flourishing and decline, the generation and control, and the movement and stillness.
The same star holds a different standing in different periods. Eight White governed in the Eighth Period and recedes in the Ninth; Nine Purple governs in the Ninth Period; One White is the qi of the period yet to come. Two Black and Five Yellow are often regarded as the "sickness talisman" and the "great sha," but if they sit in a still spot that is not being activated, one cannot pronounce misfortune merely because they appear there. Six White and Seven Red once governed and, after receding, also carry a side of rigid control, disputes, or loss. Fortune and misfortune shift with time, place, form, and combination.
