Qi Men Dun Jia Guide
Qi Men Dun Jia ("Mysterious Gates, Hidden Jia") is a traditional divination art based on time, counted with Tai Yi and Liu Ren as the "three styles". It treats the nine palaces of the Lo Shu as a map and lays the stems (the three wonders and six instruments), nine stars, eight doors and eight spirits into them according to the moment, giving four layers (heaven, earth, people and spirits) that are read to judge the conditions of a moment and the directions around it.
The "wonders" are the stems Yi, Bing and Ding; the "gates" are the eight doors; "hidden Jia" means the first stem, Jia, never appears openly but hides beneath one of the six instruments Wu, Ji, Geng, Xin, Ren and Gui.

- Lay the earth plate: place the wonders and instruments by the structure number.
- Find the Chief and Envoy: the decade head of the hour pillar gives the Chief star and Envoy door.
- Lay the heaven plate: the Chief star carries the nine stars to the palace of the hour stem.
- Lay the door plate: the Envoy door moves with the hour, turning the eight doors.
- Lay the spirit plate: the eight spirits start from the Chief's palace.
- Read it: look at patterns and at the doors, stars and spirits around the use god.
Qi Men Dun Jia AI reading: ask an AI to read the chart
After casting a chart in the Qimen chart tool, you can hand it to an AI chat service such as ChatGPT, Claude or Gemini and ask it about your question.
- On the tool page choose a "Question type" (it sets the use god). The chart time is usually the moment the question came to mind (now by default). Press "Cast the chart".
- Press "Copy for AI" under the chart. The four pillars, solar term and structure, Chief and Envoy, void and Horse, the spirits, stars, doors and stems in all nine palaces, the use-god palaces and patterns are copied as text.
- Open any AI chat and paste into the message box (Ctrl+V or ⌘V on a computer; on a phone, press and hold the box and choose Paste).
- Write your specific question after "My question:" on the last line and send it.
- Ask follow-up questions as you like; within the same conversation the AI keeps the chart in mind.
The more specific the question, the better, ideally one matter per chart. For example: "Will this week's partnership meeting go well?" "Is moving to the south-east next month a good idea?" "How will tomorrow's interview turn out?"
The copied text already asks the AI to work only from the chart data, not to calculate anything itself, and to answer in the language of this page; for another language, just say so after your question. AI readings can be wrong and may differ from what other practitioners would say, so do not rely on them alone for important decisions.
