Online Liuyao tool with changing lines and transformed hexagram
Plenty of hexagram generators stop at a name and a paragraph. A real Liuyao tool has to track which lines are changing and show what they turn into. Here is what that actually requires, and a free tool that does it.
Yarrow is a free online Liuyao tool. It casts six real lines, marks which ones are changing, shows the transformed hexagram, and identifies the significator for your specific question, so the changing lines have a clear meaning instead of sitting unexplained next to a hexagram diagram.
Ask one real question and see the changing lines and transformed hexagram directly in the result, not as an extra step you have to look up yourself.
Why most free tools stop at a hexagram name
A random hexagram generator only needs to pick one of 64 outcomes and display its text. That is enough for casual study, but it skips the part of Liuyao that makes a reading specific: which lines in that hexagram are actually moving, and what they change into. Without that step, two people asking completely different questions can land on the same generic page.
Building changing lines correctly means casting each of the six lines individually as old yin, young yang, young yin, or old yang, not just landing on a finished hexagram and working backward. That distinction is why simple generators tend to skip it: it is more work to build than a single random pick.
What a real Liuyao tool needs to show
1. A genuine six-line cast
Each line needs its own state, not a hexagram picked as a single unit. This is the only way changing lines can exist at all.
2. Which lines are changing
Old yin and old yang lines are changing; young yin and young yang lines are stable. A tool should mark this clearly per line, the way it is explained in changing lines explained, rather than leaving you to work it out from a static diagram.
3. The transformed hexagram
Changing lines flip to their opposite to produce a second hexagram. That transformed hexagram shows where the situation is heading if the current pattern plays out. A tool that shows only the primary hexagram gives you a snapshot; one that shows the transformed hexagram gives you a direction.
4. A significator for your question
The Yong Shen, or useful line, ties the abstract structure back to your actual question. Without it, changing lines and a transformed hexagram are still just structure with no obvious relevance to what you asked.
How Yarrow builds the full picture
Yarrow casts a real six-line hexagram for one concrete question, marks which lines are changing, derives the transformed hexagram, and identifies the significator for that question. The result reads all of it together in plain language: what the current line-up says, what is shifting, and where it points. See a full worked example in the Liuyao reading example.

Frequently asked questions
Is there an online Liuyao tool that shows changing lines and the transformed hexagram?
Yes. Yarrow casts six real lines, marks the changing lines, and shows the transformed hexagram along with a significator for your specific question, all as part of one free reading. Try it here.
Why do changing lines matter in a Liuyao reading?
They mark where a situation is unstable rather than fixed, and the transformed hexagram they produce shows where things are heading if the current pattern continues.
What is the difference between a hexagram generator and a Liuyao tool?
A generator returns one of 64 hexagrams and stops. A Liuyao tool casts each line individually, tracks which are changing, derives the transformed hexagram, and assigns a significator so the result connects to your actual question.
Do I need to understand changing lines before using a Liuyao tool?
No. A well-built tool explains the changing lines and transformed hexagram in plain language as part of the result.
See changing lines and the transformed hexagram in your own reading
You have seen what a full Liuyao cast should include. The fastest way to see it in practice is to ask your own question.
