Moving Lines
How to Read Moving Lines (Dong Yao) and Changed Lines in Yi Jing Divination
Static lines sketch your current baseline, while Moving Lines (Dong Yao) mark the exact switches being flipped—showing where change, friction, or breakthrough is actively unfolding.

A line becomes a Moving Line when three coins land all heads or all tails (Old Yang or Old Yin), flipping polarity to form the Changed Hexagram. For classical text reading, use the moving line count to focus on the primary line text; for Liu Yao elemental reading, check whether the moving line supports or controls your Useful God—and whether its own changed line gives it 'Return Generation' or 'Return Control.'
Why Old Yang and Old Yin transform into Moving Lines
In three-coin casting, two-of-one-side yields stable Young Yang or Young Yin (static lines). Three identical faces yield **Old Yang (○)** or **Old Yin (×)**.
Following the classical rule 'when energy reaches its extreme, it reverses,' Old Yang transforms into Yin and Old Yin transforms into Yang—creating a Moving Line and a Changed Hexagram.
Handling zero, one, or multiple moving lines in classical text reading
**Zero moving lines**: Read the Primary Hexagram's overall judgment.
**One moving line**: Focus on that specific moving line's text in the Primary Hexagram.
**Two moving lines**: Read both, giving greater weight to the upper line.
**Three moving lines**: Weigh the Primary Hexagram (present) and Changed Hexagram (trend) judgments together.
**Four or five moving lines**: Focus on the remaining static lines in the Changed Hexagram.
In Liu Yao: 'Return Generation' vs. 'Return Control'
In six-line elemental reading, a changed line acts directly on the moving line that produced it:
**Return Generation (Hui Tou Sheng)**: The changed line's element feeds the moving line—signaling growing momentum and lasting support.
**Return Control (Hui Tou Ke)**: The changed line's element controls the moving line—warning of a mid-course reversal or self-sabotage.
시작하는 방법
- 1Identify which lines carry moving markers (○ or ×) after your six throws.
- 2If no lines move, read the hexagram as a steady state anchored by Month and Day strength.
- 3If lines move, check whether the moving line is a Supporting God (feeding the Useful God) or an Obstructing God.
- 4Check how each moving line's own Changed Line acts back upon it (Return Generation vs. Return Control).
- 5Use the moving line's branch to estimate when the change will take effect.
흔한 오해
- Panicking when four or five lines move and trying to blend every line text at once.
- Relying on a moving Supporting God without noticing it suffers from 'Return Control.'
- Re-casting immediately just because you got a static hexagram with zero moving lines.

자주 묻는 질문
It indicates that the situation is relatively settled right now, so the outcome follows the baseline strength of your Useful God and Self line.
No. In standard Liu Yao rules, a Changed Line acts exclusively on the Moving Line in its own position (via Return Generation, Return Control, Clash, or Combination).
