Four pillars built from your birth datetime. Eight characters built from those pillars. A structural reading of how you make decisions, what you can sustain, and which timing windows favor which moves. No fortune. No destiny. Empirical.
The site reads like an essay on its first page and like a clinical worksheet on its last. The toggle is real — practitioners get the technical layer one click away, beginners never see it unless they ask.
No signup, no email gate, no premium tier, no tracking beyond aggregate analytics. A reference, not a funnel.
Same chart, two registers
Her chart reads as the polished-blade archetype: precision, standards, and a refusal to compromise the line between finished and not. The kind of person who would isolate a new element by hand and then refuse to patent it. Patient mastery, not flashy output.
No Chinese terms required. The structural read in plain English.
Yin Metal on Rabbit. Pillars 丁卯 / 庚戌 / 辛卯 / 甲午. Month 庚戌 supplies a strong metal root in dry-storage Earth; year 丁卯 stations Indirect Officer fire over Yin Wood wealth. The day branch 卯 is pure 乙 — the chart’s wealth layer sits directly under the self. Structure reads cleanly as 正印格 (Direct Resource), the credentialed-learning archetype practitioners use to predict scholarly advisory careers.
Same chart. Same engine. Different reading register. Yours arrives with both.
Worked examples
Each one is a full case study — chart computed from the public birth record, structure named, and a real-world life mapped onto it.

Yang Wood with Yang Metal Seven Killings overhead — the classical 'blade over the tree' configuration that maps onto a military conqueror.
Yin Metal · 辛卯
A Direct Resource structure — the credentialed-learning archetype reads almost too cleanly on the woman who won two Nobel Prizes.
Yin Fire · 丁酉
A textbook Seven Killings structure with the General's Star, Heavenly Noble, and Academic Star all stacked in the day pillar.
Yang Fire · 丙辰
An Indirect Resource chart — the structure predicts the Reed College auditing story almost verbatim.
Yang Wood · 甲申
A Yin Wood day master in late winter — the chart reads as someone who turns personal narrative into a media-scale platform.
