How this system reads
How the result is formed
Calendar and birth inputs determine the palace layout and star placements. This guide uses a fixed sample birth profile to illustrate the layout.
How to read it responsibly
Small birth-time errors may alter palace placement. The chart is a cultural interpretive model and must not be presented as scientific proof or guaranteed fate.

Then ask one question about it
A chart on its own is the draw. A reading answers the question you bring, and points at the card, line or palace it reads from.
