Overview

Qimen Dunjia is a family of traditional Chinese calendrical-divination methods that places stems, gates, stars, and deities into a nine-palace board for a declared moment. This guide separates reproducible chart facts, lineage choices, symbolic interpretations, and real-world evidence. Start with the nine-palace coordinate system, then distinguish Earth-plate and Heaven-plate stems, Eight Gates, Nine Stars, and Eight Deities. Calculation pages declare the civil-time input, solar term, Yin or Yang Dun, bureau, Xun head, placement order, and center-palace rule so the board can be checked before any meaning is assigned.

Stop rule
A reproducible chart proves only that the stated method produced the same board from the same inputs. It does not prove predictive validity, diagnose health, establish legal or financial facts, reveal another person’s private state, or override direct evidence. When records, consent, safety guidance, or professional advice conflict with a symbolic reading, the real-world evidence wins.

How the rule is formed or checked

Start with the nine-palace coordinate system, then distinguish Earth-plate and Heaven-plate stems, Eight Gates, Nine Stars, and Eight Deities. Calculation pages declare the civil-time input, solar term, Yin or Yang Dun, bureau, Xun head, placement order, and center-palace rule so the board can be checked before any meaning is assigned.

Keep the cast moment, UTC offset, method version, palace, and interacting symbols visible before adopting an interpretation.

How to use this in a reading

Before reading, record one operational question, the casting moment, UTC offset, and method version. Locate the day stem for the asker and the hour stem for the matter, then inspect their palaces, co-located layers, vigor, gate-palace relations, void, and movement flags. Add a topic-specific anchor only when the question requires one.

  • Name the visible chart fact before assigning symbolic meaning.
  • Compare the asker and matter anchors with every layer in their palaces.
  • Record at least one supporting condition and one counter-signal.
  • End with a reversible action and an observable review point.

Worked contrast

The OpenFate calculator answers “What board follows from these declared inputs?” The Wiki answers “What does this field mean, how was it produced, and when should I stop interpreting it?” For example, the calculator can show that a gate occupies a palace; the Men Po guide explains the exact gate-palace strain rule and why that flag does not decide the whole question.

Common mistake and limit

A reproducible chart proves only that the stated method produced the same board from the same inputs. It does not prove predictive validity, diagnose health, establish legal or financial facts, reveal another person’s private state, or override direct evidence. When records, consent, safety guidance, or professional advice conflict with a symbolic reading, the real-world evidence wins.
