Saju four pillars

Eight characters for the birth moment the landing already uses as its example, read right to left: hour, day, month, year. The plates hanging beneath each branch are its hidden stems — the ones a branch carries but does not show — and their width is the weight the engine gave them. Verdigris lines run from a buried stem up to the same character standing on the surface: it has emerged. The short runs across the surface are the clashes and combinations the engine found.

Compact mobile view · hidden stems are stacked independently by pillar.

One example chart. Nothing here is a claim about the person born at this moment, and the landing would label it as an example in the same words the matrix already uses.
