Cast a Meihua Yishu hexagram

First, write the one matter you want to ask about. Keep it to something already underway, or a decision you have to make soon. A specific question keeps Body and Use from sliding onto a second matter.

Second, pick one method. The default uses the clock frozen when you ask. You can instead give three positive integers. One cast uses one method. Do not mix the clock and the three numbers.

Third, read the hexagram. The original, the nuclear, the changed, Body, Use, and the five-phase relation are computed once. The same input always yields the same hexagram. The reading does not change a line afterward.

Write the question before you cast. One sentence is enough: who, which matter, and what you want to judge. Do not put two unrelated matters in the same hexagram.

You do not need a birth time. A time cast uses the moment you ask, not the moment you were born. A three-number cast uses the three integers you give, and it does not read a birth chart.

If you are not sure the matter fits, start with what Meihua is.

Adapt these to your own matter. Questions about how you are holding up describe a feeling. They are not a diagnosis.

• A relationship: Will they write back this week? After we meet, does this continue?
• Work: Should I keep waiting on this job? If I push now, where does it stick?
• Money already spent: Is there still a way through? Should I pause this expense?
• A choice: Of the two things in front of me, which comes first? Should I settle this now?
• How you are holding up: Sleep has been light. Will this stretch ease? This is not a medical opinion.
• A document or a lost thing: Which step is it stuck on? Is it still in the place I already looked?

Meihua turns this one question into a hexagram you can check. The input is the matter you wrote, plus one method: the clock frozen when you ask, or three positive integers. The output is the upper trigram, the lower trigram, the moving line, the original hexagram, the nuclear hexagram, the changed hexagram, Body, Use, the relation between them, and the seasonal mark the month gives each one. Check those fields before you read the wording.

fatequery casts the hexagram with a fixed rule, then lets the AI explain only the fields already on it. A different method, clock, or set of numbers makes a different hexagram. The same input always yields the same one.

After the cast, these items are calculated, not added later as commentary: the original hexagram and its two trigrams, which line moves, the nuclear hexagram, the changed hexagram, the trigram and phase of Body and of Use, the one relation between them, and the seasonal mark on each.

Read in this order. Start with Body and Use. Body is your side. Use is the matter. Take one five-phase relation. Then see which line moves. The original hexagram is the cast. The changed hexagram does not erase it. The nuclear hexagram uses the middle four lines and has no moving line of its own. The changed hexagram flips only the moving line. Last, read the seasonal mark on Body and on Use. If the three hexagrams do not say the same thing, keep all three. Do not move a line to force one sentence.

When another hexagram does not match, check in this order. Do not start by rewriting whether Body and Use are favorable.

First, the method. One cast uses either the clock or three numbers. A time cast and a three-number cast are not the same hexagram.

For a time cast, check the lunar month and day. Do not compare them with the civil date. Then check whether 23:00 has turned the day. After that point the lunar day moves forward.

For three numbers, check the three integers, and whether a remainder of 0 was counted as 8 or 6. A different remainder rule changes the trigrams.

Then the moving line. Whether it sits in the upper or the lower trigram decides which one is Use. One line off, and the changed hexagram is a different hexagram.

Last, the month mark. It only labels the season. It does not change the hexagram already cast. Compare the wording only after the fields match.

The names are defined in Meihua.

Meihua on fatequery is an online cast for people who study the method. Write a question and the hexagram is cast. You can read the chart, continue with an AI reading, or follow the names in the knowledge base.

The reading starts from Body and Use, then the original, nuclear, and changed hexagrams, the moving line, and the month mark. The conclusion comes first, then the fields it rests on. It does not turn Meihua into Liu Yao Najia, or into the BaZi Ten Gods.

Study, and matters of work or a relationship that are already underway, can be read here for reference. If you are not sure what you can ask, start with what Meihua is.
