Lo Shu (洛书)

Numbers structure the model; they are not standalone luck charms.

Definition

The Lo Shu is the 3×3 square of numbers 1–9 with 5 in the centre, rhymed as ‘nine on the head, one on the foot.’ Flying-star practice maps stars and palaces onto this grid.

How to Check

Draw the square and align north with your plan.
Do not mix Lo Shu palaces with Hetu generate-number pairs.

Classical Basis

Han sources record the pattern; later compass arts adopted it. Calendar Tai Sui is a different tradition.

Application

·Period 9 places purple 9 in the central palace.

Common Effects

·Reversing the square flips directional readings.
·Confusing Lo Shu with calendar gods misstates both systems.

Remedy Direction

Keep one reference square; verify software after period updates.
