Period 8: Chén sitting, Xū facing
The natal chart
North-up. Each palace shows mountain star · water star with the base (period) star beneath; the facing and sitting palaces are marked.
Palace by palace
| Palace | Mountain ★ | Water ★ | Traditional note |
|---|---|---|---|
| NW (facing) | 8 — White 8 | 1 — White 1 | The facing palace: water star 1 governs the traditional wealth reading here. |
| SE (sitting) | 6 — White 6 | 8 — White 8 | The sitting palace: mountain star 6 governs the traditional people-and-health reading here. |
| N | 3 — Jade 3 | 5 — Yellow 5 | Two untimely stars by Period-9 readings — tradition keeps this palace quiet and uncluttered. |
| NE | 1 — White 1 | 3 — Jade 3 | Mixed pairing: Jade 3 is the untimely component; tradition avoids activating it. |
| W | 9 — Purple 9 | 2 — Black 2 | Mixed pairing: Black 2 is the untimely component; tradition avoids activating it. |
| Center | 7 — Red 7 | 9 — Purple 9 | Mixed pairing: Red 7 is the untimely component; tradition avoids activating it. |
| E | 5 — Yellow 5 | 7 — Red 7 | Two untimely stars by Period-9 readings — tradition keeps this palace quiet and uncluttered. |
| SW | 4 — Green 4 | 6 — White 6 | A settled pairing by traditional readings; suitable for active daily use. |
| S | 2 — Black 2 | 4 — Green 4 | Mixed pairing: Black 2 is the untimely component; tradition avoids activating it. |
How this chart was derived
- Period 8 enters the center and flies forward: the base layer.
- The base star at the facing palace (9) becomes the water star in the center, flying forward per the Xū mountain's polarity.
- The base star at the sitting palace (7) becomes the mountain star, by the same rule for Chén.
This is the standard xia gua (下卦) method; facings within ~3° of a sector boundary invoke the substitute ti gua (替卦) method in some lineages, which this library does not yet cover. Which period a building belongs to (construction vs. move-in vs. gut renovation) is itself a school question — we note it rather than settle it. The annual stars for the current year overlay this chart; see Flying Stars 2026.
As with everything in this library: natal charts are a traditional system with no scientific support — the full picture is on our evidence page.
Frequently asked questions
What type of chart is the Period 8 Chén-sitting, Xū-facing home?
It is a Mountain Up the Hill, Water Down the River (上山下水) chart. The timely stars land in each other's places — the configuration tradition rates weakest, managed with landscape adjustments rather than abandoned.
Which homes does this chart apply to?
Homes completed (by most schools' convention) during Period 8 — February 2004 – February 2024 — whose facing direction falls between 292.5°–307.5° on a compass, the Xū (戌) mountain. Schools differ on whether construction, move-in, or major renovation sets the period, and facings within about 3 degrees of a sector boundary invoke the substitute (ti gua) method some lineages use. This page shows the standard xia gua chart.
How do I read the three numbers in each palace?
The large pair are the functional stars: the mountain star (left) governs the traditional people-and-health reading of the palace, the water star (right) the wealth reading. The small number is the base (period) star. In this chart, the timely star 8 appears as the mountain star at the facing and water star at the sitting — the reversed arrangement.
