Trigrams, Ti/Yong, and Five Phases

The calculation gives you a hexagram. The framework tells you how to read it.

Plum Blossom interpretation usually rests on four layers:

1. Trigram image.
2. Ti/Yong, or body and function.
3. Five Phase relationship.
4. I Ching hexagram and line text.

If one layer contradicts another, do not flatten them into a single slogan. Let each layer say its part.

Trigram Images

Trigram	Image	Practical reading tone
Qian ☰	Heaven	strength, direction, authority, initiative
Dui ☱	Lake	exchange, speech, pleasure, opening
Li ☲	Fire	clarity, visibility, attachment, recognition
Zhen ☳	Thunder	shock, activation, beginning, movement
Xun ☴	Wind	penetration, gradual influence, entry
Kan ☵	Water	danger, depth, difficulty, hidden flow
Gen ☶	Mountain	stillness, boundary, stopping, restraint
Kun ☷	Earth	receptivity, support, field, capacity

Do not read the trigrams as fixed personalities. Read them as images in relation.

Fire over Heaven is not just “Fire plus Heaven.” It is visibility above strength, clarity needing a vehicle, attachment resting on power, or brightness carried by structure.

Ti and Yong

Ti (體) is the body, base, or matter being read.

Yong (用) is the function, active force, pressure, use, or event acting upon it.

Different teachers assign Ti and Yong in different ways. A simple beginner rule:

Question focus	Ti	Yong
Self and situation	Lower trigram	Upper trigram
Moving-line emphasis	Trigram without the moving line	Trigram containing the moving line
Object interrupted by event	The object or stable base	The interruption or active cue
Relationship question	The querent side	The other side or acting force
Outcome pressure	Present body of the matter	Emerging movement

The important thing is to assign Ti/Yong before deciding whether the reading is favorable. Do not borrow WWG’s Yong Shen or Six Relatives logic here. Plum Blossom’s body/function distinction works at the trigram and image level, not as a six-line target-selection chart.

Five Phase Direction

The Five Phase relation tells you how the active force behaves toward the body.

Relation	Reading
Yong generates Ti	The active force supports the matter.
Ti generates Yong	The matter feeds the active force, but may be drained by doing so.
Yong controls Ti	The active force pressures, restricts, or disciplines the matter.
Ti controls Yong	The matter can manage, restrain, or use the active force.
Same phase	The two sides share nature, but may compete or reinforce.

This fixes a common confusion. Generation is not always “good” and control is not always “bad.” If the body feeds the function, the outcome may be productive, but the body pays a cost. If the body controls the function, the situation may be difficult, but manageable.

Course Case

The workshop proposal case produced Fire over Heaven, Hexagram 14, changing at line 2.

Using the beginner assignment:

Layer	Reading
Ti	Qian, Heaven, the proposal’s structural base
Yong	Li, Fire, visibility and presentation
Phase relation	Fire controls Metal
Meaning	The visible face of the project pressures the structure. Presentation matters, but it can overheat the base if the proposal is all shine and not enough vehicle.
Changed hexagram	Fire over Fire, Clarity
Direction	The question moves further into visibility, attachment, and the need for clear form.

This is more useful than “good” or “bad.” It says: the proposal has charge, but the support structure must be strong enough for the visibility it seeks.

The Text Still Matters

Plum Blossom is not only trigram math. Once the hexagram and moving line are known, read the received I Ching language.

Use the text to constrain the imagination:

• Primary hexagram: the moment’s main image.
• Moving line: the turning point.
• Changed hexagram: the direction of change.
• Trigram and Five Phase frame: the energetic mechanics.

The stronger reading is the one where these layers illuminate each other without being forced.
