Meihua Yishu: host, guest, and one changing line
Meihua takes a number at the moment of the question and turns it into one hexagram, its nuclear hexagram, and one changed hexagram. It is not Liu Yao najia and not a nine-palace board. Birth data is not an input.

Divination
Time casting uses year branch, lunar month and day, and hour branch. Three-number casting uses three integers from 1 to 99999. 23:00 starts the next day.

Overview
An overview of Meihua
Meihua casts from numbers at the moment of the question. Those can be three stated numbers, or the time of the question converted into numbers. A birth date is not an input.
View definition →
Host and guest
Host trigram and guest trigram
Meihua splits the cast hexagram into host and guest. The host is the asker’s side of the matter. The guest is the side that meets it. Generation and control are read on those two trigrams first, not on two people’s names.

Time and the three numbers
Casting from time or from three numbers
Meihua casts from numbers at the moment of the question. Those can be three stated numbers, or the time of the question converted into numbers. A birth date is not an input. Once the numbers are fixed, the hexagram is fixed.

Nuclear and changed hexagrams
The nuclear hexagram and the changed hexagram
Beside the primary hexagram, Meihua reads a nuclear hexagram and a changed hexagram. The nuclear one is the inner structure rebuilt from the middle four lines. The changed one is the condition after the moving line. Read the three together.

Generation and control
Generation and control are read on host and guest
The calculation Meihua actually finishes is the element relation of the host and guest trigrams. Generation, control, and matching describe how the two sides meet. They are not a medical or legal cause.

Use and limits
What questions a Meihua cast can hold
Meihua fits one stated question whose numbers are already fixed. It does not read a whole life, and it does not turn a hexagram into a medical or financial decision.

What host and guest are
The moving line picks one of the two trigrams as the guest (“yong”), the trigram of the matter asked. The other trigram is the host (“ti”), the asker’s side. Their elements are then compared: guest generating host, or the same element, is the smoother case; host generating guest spends; host controlling guest is effort that can still hold; guest controlling host is the setting pressing on the asker.
The primary hexagram is the present structure. The nuclear hexagram is rebuilt from the inner four lines. The changed hexagram flips the moving line. All three stay in view. The primary hexagram is not the ending.
What fateshow calculates
Time casting reduces the year branch, lunar month, lunar day, and hour branch to the upper trigram, lower trigram, and moving line. Three-number casting takes the first integer for the upper trigram, the second for the lower, and the third for the moving line. The same three numbers always return the same hexagram.
The tool does not look up a birth chart, and it does not install najia stems on the lines. Element comparison is the calculation this method actually finishes.
What it is not
It is not a six-line coin cast, even though both use a hexagram. Six relations, world and response, and void branches are Liu Yao objects and are absent here.
A hexagram is for the question just asked. It does not become a natal type.
Safety boundary
Host and guest are a conditional frame for one question. They are not medical, legal, or financial advice, and an element relation is not an instruction to spend, sue, or treat an illness.
Common mistakes
- Reading Meihua lines as Liu Yao six relations.
- Treating the primary hexagram as the outcome and ignoring the moving line.
- Mixing a time cast and a three-number cast as if they were one input.

Open tool →Frequently asked questions
Which input should I use?
Either the clock or three integers, not both at once. The chart states which rule produced it.
What is the nuclear hexagram?
A second hexagram built from lines two through five of the primary. It is context, not a replacement verdict.
Does 23:00 change the day?
Yes in the time method. From 23:00 the cast counts the next day.
