No moving line
The situation may be more stable, fixed, or simply slower to change than the user hopes.
Moving lines
What a moving line changes in Liu Yao.
A moving line matters because it shows that something in the situation is not static. It adds motion, tension, transition, or a turning point. That is one reason Liu Yao can feel more alive than a broad descriptive reading.
Why it matters
Movement is what makes the question feel alive.
One moving line
This often gives a focused place to look: the point of change, pressure, or weakness in the current question.
Several moving lines
This can suggest a noisier, less settled situation where more variables are in motion at once.
Why users care
Because they want to know not only what the situation is, but whether it is likely to shift, and where that shift may begin.
Best next step
Pair structure with a better question.
Once users understand movement, they ask better Liu Yao questions and get more useful readings out of the same tool.
