Every branch in the chart carries one of five elements. This lesson adds two directional relations—generation and control—without deciding whether either relation is active or important in the reading.

Branch-to-element lookup

EarthChou, Chen, Wei, Xu
MetalShen, You

The two directional cycles

Generation:

Water → Wood → Fire → Earth → Metal → Water

Control:

Wood → Earth → Water → Fire → Metal → Wood

Direction must be explicit. “Wood controls Earth” is not interchangeable with “Earth controls Wood.” When adding an arrow to a worksheet, write both the source and target.

Worked chart: Case 00035

Add the branch elements to Hexagram 3:

LineBranchElement
1ZiWater
2YinWood
3ChenEarth
4ShenMetal
5XuEarth
6ZiWater

The chart visibly contains these possible phase directions:

  • Water on lines 1 and 6 generates Wood on line 2.
  • Wood on line 2 controls Earth on lines 3 and 5.
  • Earth on lines 3 and 5 generates Metal on line 4.
  • Metal on line 4 generates Water on lines 1 and 6.

That list is a relationship map, not a claim that every possible arrow is operating. Motion, target selection, calendar state, and the declared judgment order decide which relations are later evaluated.

Reproducible exercise

For each statement, mark generation, control, or neither:

DirectionResult
Water → Woodgeneration
Metal → Woodcontrol
Earth → Metalgeneration
Fire → Waterneither; Water controls Fire in the reverse direction
Wood → Woodsame element, not generation or control

Failure control: if reversing the arrow leaves your answer unchanged, you have replaced a directional operation with a vague association. Rewrite the relation as a sentence with a subject and object.

Boundary

Generation is not automatically favorable; control is not automatically unfavorable. Those are interpretive judgments that depend on which line is selected and what role each line plays. The Five Phases here are chart mechanics, not moral labels or physical causes.

Source note

The complete branch-element table and two directional cycles define the mapping used in this course. Write the direction explicitly before assigning a relationship.

Next: Continue to Branch Relationships and mark fixed branch-pair flags separately from the Five-Phase arrows.
