Chapter 05
Movement, Strength, and Timing
Dynamic weighting and timing
1. Learning Objectives
After completing this chapter, readers should understand:
- Liu Yao judgment does not only ask “which line represents the matter,” but also whether that line has strength, whether it moves, and whether it is activated by time.
- Moving lines represent change, trigger, and action; still lines represent relative stability, no current activation, or the need to wait.
- Strength and weakness describe how strong a line is under current time conditions.
- Month Branch and Day Branch strongly influence the force of each line.
- Emptiness, entering tomb, clash, combination, and similar states affect whether a matter can land, whether it is blocked, and whether it is activated.
- Timing is the Liu Yao method for judging “when change may happen,” but it is harder than judging the trend.
- Liu Yao does not only ask “can it succeed,” but also “does it have strength now, where is movement, and when might change occur.”
- Beginners should first learn to judge trend and obstruction, then gradually learn timing.
2. Why Read Movement, Strength, and Timing?
The previous chapters have already explained:
- The Self line represents oneself;
- The Other line represents the other party or outside;
- The Useful Line represents the matter being asked about;
- The Six Relatives represent different human and matter themes;
- The Six Spirits assist in observing the atmosphere of the matter.
But merely knowing “who represents what” is not enough.
We must continue asking:
Does this Useful Line have strength?
Is it moving or still right now?
Who generates it, and who controls it?
Is it empty?
Is it held by combination?
Does it enter tomb?
When might it be activated?
For example, when asking whether a client will pay, the Wealth line is the Useful Line.
But the presence of the Wealth line does not mean payment is certain.
We must also see:
- Whether the Wealth line is strong;
- Whether the Wealth line moves;
- Whether the Wealth line generates Self;
- Whether the Wealth line is empty;
- Whether the Wealth line is controlled by a Sibling line;
- Whether the Wealth line is held by combination;
- When the Wealth line may leave emptiness, meet clash, meet combination, or receive support.
This is the importance of movement, strength, and timing.
The core of Liu Yao judgment is not only “finding the Useful Line,” but judging further:
Whether the Useful Line has the ability to act.
3. What Is a Moving Line?
A moving line is a line that changes.
During casting, if a certain line is Old Yang or Old Yin, that line activates and becomes a moving line.
A moving line has several important meanings:
- The matter has change;
- The theme represented by this line is triggered;
- The person, matter, or object represented by this line takes action;
- This line produces more obvious effects on other lines;
- After changing, the moving line forms a changed line and affects the later trend.
For example:
- Wealth line moving: finance, clients, resources, and income themes are activated;
- Officer/Ghost line moving: position, pressure, rules, illness imagery, object, and related themes are activated;
- Parent line moving: contracts, messages, certificates, and documents are activated;
- Sibling line moving: competition, friends, partnership, and division of wealth are activated;
- Children/Descendants line moving: products, output, pressure relief, and children-related themes are activated.
A moving line is not simply “good” or “bad.”
It only shows that the matter is moving.
If movement is favorable, it may push the matter forward;
If movement is unfavorable, it may trigger obstruction.
4. What Is a Still Line?
A still line is a line that has not activated.
A still line indicates:
- Temporary stability;
- No obvious action;
- The matter has not yet been triggered;
- The related person or factor is not active for now;
- External time may be needed to activate it.
A still line does not mean it is useless.
If a still line is strong, powerful, and supported by month and day, it is still important.
If a moving line is weak, empty, and controlled, it may not truly be able to act.
For example, when asking about payment, if the Wealth line is still but strong and supported by the Day Branch, there may still be a collection opportunity, though it may not happen immediately.
If the Wealth line moves but is empty and changes into returning control, there may first be movement and then obstruction.
Therefore, do not simply say:
Moving is good, still is bad.
The correct understanding is:
Moving lines show change; still lines show state.
Both movement and stillness must be judged together with strength, generation and control, emptiness, and changed lines.
5. Basic Functions of Moving Lines
Moving lines have stronger action than still lines.
This is because moving lines actively generate or control other lines, and also transform into new lines.
Common functions of moving lines include:
Moving and generating Self
If a moving line generates the Self line, it usually means a force comes to help oneself.
For example, Wealth moving and generating Self may indicate money has an intention to come in financial questions.
Parent moving and generating Self, in message or contract questions, may indicate documents or notifications are favorable to oneself.
Other line moving and generating Self, in partnership or relationship questions, may indicate the other party takes supportive action.
Moving and controlling Self
If a moving line controls the Self line, it usually means a force creates pressure on oneself.
For example, Officer/Ghost moving and controlling Self may indicate pressure, rules, role requirements, illness imagery, or external constraints becoming stronger.
Sibling moving and controlling Self may indicate peers, competitors, or partners creating pressure on oneself.
Wealth moving and controlling Self, in some questions, may indicate practical responsibility or financial pressure.
Moving and generating the Useful Line
If a line moves and generates the Useful Line, it means there is force supporting the matter being asked about.
For example, asking about money, Children/Descendants moving and generating Wealth may indicate products, services, or output producing income.
Asking about contracts, Officer/Ghost moving and generating Parents may indicate rules or position pushing documents to form.
Asking about relationship, Other line moving and generating the relationship Useful Line may indicate the other party pushes a relationship theme.
Moving and controlling the Useful Line
If a line moves and controls the Useful Line, the matter being asked about is obstructed.
For example, asking about money, Sibling moving and controlling Wealth often shows competition, division of wealth, delayed payment, or expense offset.
Asking about work, Children/Descendants moving and controlling Officer/Ghost may be unfavorable to role stability, or show unwillingness to be managed.
Asking about contracts, Wealth moving and controlling Parents may show practical interests affecting the paperwork process.
6. Changed Lines and Transformation Images
After a moving line changes, it forms a changed line.
The changed line shows the direction after the matter changes.
Common transformation images in Liu Yao include:
- Transforming back to generate;
- Transforming back to control;
- Transforming into advancing spirit;
- Transforming into retreating spirit;
- Transforming into emptiness;
- Transforming into tomb;
- Transforming into combination;
- Transforming into clash.
Beginners do not need to study all of them deeply at first, but should first understand the two most important types:
Transforming back to generate
After the moving line changes, the changed line generates the moving line. This is called transforming back to generate.
It usually indicates:
- The matter later receives support;
- There is added force after action;
- Help appears during development;
- The original force is strengthened.
For example, the Useful Line moving and transforming back to generate is usually more favorable than transforming back to control.
But it is still necessary to see whether the Useful Line itself is what the question needs.
Transforming back to control
After the moving line changes, the changed line controls the moving line. This is called transforming back to control.
It usually indicates:
- The matter moves first and then meets obstruction;
- There is action at the beginning, but later pressure appears;
- A factor activates and is then restricted;
- A plan moves forward and then repeats or reverses.
For example, when asking about cooperation, if the cooperation Useful Line moves but transforms back to control, cooperation may advance, but later conditions or practical issues may suppress it.
When asking about payment, if the Wealth line moves and transforms back to control, there may be signs of payment, but later it is blocked by process, funds, or other conditions.
7. What Are Strength and Weakness?
Strength and weakness describe the force of a line.
Liu Yao does not only look at whether a line appears, but whether it has power.
A line with power can act more effectively.
A line without power may be hard to land even if it represents a matter.
Strength can be understood as:
- Having qi;
- Having force;
- Having foundation;
- Being able to act;
- Being easy to manifest.
Weakness can be understood as:
- Weak force;
- Not yet becoming substantial;
- Hard to act;
- More restricted;
- Temporarily powerless.
For example, when asking whether a client will pay, a strong Wealth line means the money has force.
A weak Wealth line means financial conditions are insufficient or money is not easy to arrive.
When asking about a position, a strong Officer/Ghost line means the position or pressure is more obvious.
A weak Officer/Ghost line may mean the role opportunity is unstable, or pressure has not formed.
8. How Month Branch Affects Strength
The Month Branch is the Earthly Branch of the current month.
It represents the major environmental qi of the month.
The Month Branch has a strong influence on the force of each line in the hexagram.
If a line receives generation or support from the Month Branch, its strength increases.
If a line is controlled by the Month Branch, its strength decreases.
If a line is at the Month Branch, it is usually very strong.
If a line is clashed and damaged by the Month Branch, the matter is likely to be turbulent or damaged.
For example:
- In Yin and Mao months, Wood qi is strong;
- In Si and Wu months, Fire qi is strong;
- In Shen and You months, Metal qi is strong;
- In Hai and Zi months, Water qi is strong;
- In Chen, Xu, Chou, and Wei months, Earth qi is obvious.
If the Useful Line belongs to Wood and it is in Yin or Mao month, it usually receives help from seasonal command.
If the Useful Line belongs to Wood but is in Shen or You month, where strong Metal controls Wood, its strength may be damaged.
The Month Branch is like the larger climate.
It decides whether a certain type of Five Element has environmental support at this stage.
9. How Day Branch Affects Strength
The Day Branch is the Earthly Branch of the current day.
The Day Branch also has important effects on every line in the hexagram.
The Day Branch can:
- Generate a line;
- Control a line;
- Clash a line;
- Combine with a line;
- Support a line;
- Damage a line;
- Activate a line.
If the Useful Line receives generation or support from the Day Branch, the force of that day helps it.
If the Useful Line is clashed by the Day Branch, the matter may be activated, or it may be broken by clash.
If the Useful Line combines with the Day Branch, the matter has involvement, may be held by combination, or may have cooperation conditions.
If the Useful Line is at the Day Branch, it usually has strong current force and a strong sense of reality.
The Day Branch is closer and more specific than the Month Branch.
It can be understood this way:
The Month Branch is like the climate of the month.
The Day Branch is like the trigger point of the day.
The Month Branch decides the larger environment, while the Day Branch decides the specific action of the current day.
10. Strength Cannot Be Judged from One Factor Only
When judging strength and weakness, do not look only at the Month Branch or only at the Day Branch.
Read together:
- Whether it receives the Month Branch;
- Whether it receives the Day Branch;
- Whether it moves;
- Whether other lines generate or support it;
- Whether other lines control it;
- Whether it is empty;
- Whether it enters tomb;
- Whether it is clashed and damaged;
- Whether it transforms into advancing or retreating;
- Whether it transforms back to generate or transform back to control.
For example, a Useful Line may receive generation and support from the Month Branch, but also be empty. This means it has qi but is temporarily not solid.
A Useful Line clashed by the Day Branch may mean the matter is activated, but if the Useful Line itself is weak, it may also be broken by the clash.
A Useful Line may move, but if it transforms back to control, it has action but later obstruction.
Liu Yao judgment is detailed precisely because these factors are integrated.
11. What Is Emptiness?
Emptiness means that a line is temporarily unreal, unsettled, floating, or not in place.
Common meanings include:
- The matter has not yet taken shape;
- The other party’s state is unclear;
- The message has not arrived for now;
- Money has not arrived for now;
- The plan is still at the idea stage;
- Conditions have not landed.
For example:
Asking about money, an empty Wealth line may mean the money has not arrived for now.
Asking about a contract, an empty Parent line may mean the document has not been settled.
Asking about relationship, an empty Other line may mean the other person’s attitude is unclear.
Asking about a position, an empty Officer/Ghost line may mean the position is not truly confirmed yet.
But emptiness does not mean nothing forever.
Emptiness may change when the line leaves emptiness, is clashed out of emptiness, or becomes filled.
Therefore, when seeing emptiness, do not immediately say “there is no result.”
A more accurate statement is:
At present it is temporarily not solid and has not landed. It needs conditions to become filled or to be activated.
12. What Is Entering Tomb?
Entering tomb means a line is stored, hidden, and difficult to act.
Tomb can also be understood as storage, collection, enclosure, or temporary containment.
For example:
- Wealth line entering tomb: money is stored away and not released for now;
- Parent line entering tomb: messages or documents are hidden and not coming out for now;
- Officer/Ghost entering tomb: pressure or position is temporarily suppressed;
- Other line entering tomb: the other party’s state is withdrawn and unwilling to show;
- Self line entering tomb: one’s own state is closed, trapped, or hard to act.
Entering tomb is not necessarily completely bad.
When asking about storage, collection, real estate, or long-term accumulation, entering tomb can sometimes mean containment and stability.
But when asking about fast progress, entering tomb often means it is not easy to move.
Sometimes the tomb must be clashed open before the matter can appear.
13. What Is Combination?
Combination indicates involvement, union, cooperation, being held, or binding.
In Liu Yao, when a line is combined, several situations may exist:
- There is a cooperative relationship;
- There is emotional involvement;
- It is dragged by a condition;
- It is occupied by someone else;
- It cannot act freely for the moment;
- It is bound to a certain factor.
For example:
Asking about payment, a combined Wealth line may mean the money is stuck by process, contract, conditions, or another person.
Asking about relationship, a combined Other line may mean the other person has involvement, or the relationship is held by some factor.
Asking about work, a combined Officer/Ghost line may mean the position is bound to a condition, or there is an employment connection.
Combination is not necessarily good or bad.
See whether what is combined is the Useful Line or an unfavorable line.
A combination that comes to generate Self may be favorable.
A combination holding the Useful Line may delay the matter.
A combination holding the unfavorable line may instead reduce pressure.
14. What Is Clash?
Clash indicates stirring, change, opening, scattering, or breaking.
In Liu Yao, clash has several meanings:
- Activation;
- Change;
- Opening;
- Scattering;
- Damage;
- Sudden change.
For example:
Asking about messages, a clashed Parent line may mean the message is activated, or that the message is unstable.
Asking about money, a clashed Wealth line may mean wealth moves, or wealth scatters.
Asking about relationship, a clashed Other line may mean the other person’s state changes and the relationship is unstable.
Asking about cooperation, a clashed Useful Line may mean conditions change and cooperation shifts.
Clash is not necessarily bad.
If a line is held by combination, clash may open it.
If a line is very stable, clash may bring change.
If a line is weak and then clashed, it may be broken by the clash.
To judge clash, see whether the line itself has strength.
15. What Is Timing?
Timing is the Liu Yao method for judging when a matter may happen or change.
For example:
When will the money arrive?
When will the other party reply?
When can the contract be signed?
When will the interview result come out?
When will the relationship change?
These all belong to timing questions.
Timing is one of the more difficult parts of Liu Yao, because time judgment requires many factors to be integrated.
Beginners should not start by pursuing exact dates.
A more reasonable learning order is:
- First judge whether the matter has opportunity;
- Then judge whether the current condition has strength;
- Then judge where the obstruction lies;
- Finally examine when the matter may respond.
If the trend judgment is not yet clear, directly judging timing is very easy to misread.
16. Common Timing Approaches
There are many timing methods. At the beginner stage, first understand several basic directions.
Useful Line leaving emptiness
If the Useful Line is empty, a result may need to wait until it leaves emptiness, is clashed out of emptiness, or becomes filled.
For example, asking about messages, an empty Parent line may mean the message has not arrived for now.
When the Parent line leaves emptiness or is clashed into reality, the message may appear.
Useful Line meeting clash
If the matter is held by combination, meeting clash may open it.
If the matter is still, meeting clash may activate it.
If the matter is weak, meeting clash may break it.
Therefore, clash can sometimes be the response point.
Useful Line meeting combination
If the matter is scattered, meeting combination may gather it.
If cooperation is needed, meeting combination may bring progress.
But if the Useful Line is already held by combination, it may also mean delay.
Useful Line receiving generation and support
When the Useful Line receives generation and support at a certain time, the matter may become stronger.
For example, if the Useful Line belongs to Wood, Water day or Wood day may increase its strength.
If the Useful Line belongs to Fire, Wood day or Fire day may make it stronger.
Tomb or storehouse being clashed open
If the Useful Line enters tomb, it may be necessary to wait until the tomb is clashed open before the matter appears.
For example, if the Wealth line enters tomb, one may need to wait for the day that clashes the tomb before money has a chance to be released.
17. Timing Cannot Be Applied Mechanically
Timing judgment cannot mechanically say:
Clash always means it happens.
Combination always means it happens.
Leaving emptiness always means it happens.
The Useful Line day always means it happens.
Time is only a triggering condition.
You must also see whether the matter itself has strength.
If the Useful Line has no qi, is controlled, empty, and heavily damaged, it may not succeed even when a certain time arrives.
If the Useful Line is strong and powerful, but only temporarily held by combination or emptiness, then when it meets clash, combination, or leaves emptiness, response is more likely.
Therefore, timing must be built on trend judgment.
18. Case: When Will the Client Pay?
Question:
When will this client pay?
Focus on the Wealth line and Other line.
If the Wealth line is empty, money is temporarily not solid.
If the Wealth line is strong but empty, it may mean money or payment intent exists, but has not landed yet.
Timing can look at when the Wealth line leaves emptiness, is clashed into reality, or receives generation and support.
If the Wealth line is held by combination, payment may be stuck by process or conditions.
Timing can look at when the combining factor is clashed open.
If a Sibling line moves and controls Wealth, there may be expense offset, competition, delayed payment, or profit division.
Even when the timing point arrives, this obstruction must first be solved.
Practical suggestion:
Payment has opportunity, but it may not yet have landed or may be stuck in process. Actively confirm payment conditions, invoice, and approval points rather than only waiting for time to pass.
19. Case: When Will the Other Party Reply?
Question:
When will the other party reply?
Read the Parent line, Other line, and Vermilion Bird.
The Parent line represents messages.
Vermilion Bird represents communication, language, and information.
The Other line represents the other party.
If the Parent line is empty, the message has not arrived for now.
If the Parent line moves, the message has movement.
If the Parent line carries Vermilion Bird, communication imagery is more obvious.
If the Other line generates Parents, the other party may take action to send a message.
If the Parent line is held by combination, the message may be delayed.
If the Parent line is clashed, there may suddenly be a message, or the message may be unstable.
Practical suggestion:
When there is message movement, waiting or a light reminder is possible. If the Parent line is empty, weak, and controlled, do not expect an immediate reply too strongly.
20. Case: Can This Position Be Confirmed?
Question:
Can this position be confirmed?
Read Officer/Ghost, Parent line, and Self line.
Officer/Ghost represents the position.
Parents represent contract, offer, and notification.
The Self line represents oneself.
If Officer/Ghost is strong and generates Self, the position is favorable to oneself.
If the Parent line moves and generates Self, there is an opportunity for notification or contract.
If Officer/Ghost is empty, the position may not yet be confirmed.
If the Parent line is held by combination, the contract process may be stuck.
If Officer/Ghost is controlled by Children/Descendants, the position may be unstable, or oneself may be unwilling to be constrained.
Timing can look at when Officer/Ghost or the Parent line leaves emptiness, meets generation, meets combination, or meets clash.
Practical suggestion:
Whether the opportunity is confirmed does not depend only on the role itself, but also on whether written confirmation lands. If the position has strength but the Parent line is weak, there may be a verbal opportunity while written confirmation still requires waiting.
21. Movement, Strength, and Practical Advice
Liu Yao judgment ultimately needs to become practical advice.
For example:
Useful Line is strong and generates Self
Move forward actively, but execute steadily.
Useful Line is weak and empty
Do not rush. First wait for conditions to land.
Useful Line moves and transforms back to control
The matter has movement, but later resistance is obvious. Prepare for it in advance.
Unfavorable line moves and controls Self
Pressure is increasing. Respond carefully.
Useful Line is held by combination
The matter is constrained by a condition. Find the sticking point.
Useful Line enters tomb
The matter is temporarily stored away. Do not force it. Wait for the tomb to open or conditions to mature.
Self line is weak and controlled
One’s capacity is insufficient. Reduce risk and seek support.
Self line is strong and controls Useful Line
One has control, but should avoid being overly forceful.
This is the practical value of Liu Yao.
22. Key Points of This Chapter
This chapter should be remembered through the following key points:
- Moving lines represent factors currently changing in the matter.
- Still lines represent relative stability or no current activation.
- Moving lines are not necessarily good, and still lines are not necessarily bad.
- For moving lines, read whom they generate, whom they control, and what they change into.
- Transforming back to generate usually means later support.
- Transforming back to control usually means movement first, obstruction later.
- Strength and weakness indicate the force of a line.
- Month Branch is like the climate of the month; Day Branch is like the trigger point of the day.
- Emptiness means temporarily unreal or unsettled.
- Entering tomb means being stored, hidden, or difficult to express.
- Combination indicates involvement, cooperation, or being held; clash indicates change, opening, or breaking.
- Timing is the method for judging when change may happen, but it must be built on trend judgment.
23. Common Questions
Does a moving line always represent something good?
No.
A moving line only represents change.
Change may bring opportunity, and it may also bring obstruction.
Is a still line useless?
No.
If a still line is strong, it is still important.
It simply has no obvious action for now.
Does Useful Line in emptiness always mean no result?
Not necessarily.
Emptiness means temporarily unreal or unsettled.
There may still be change when it leaves emptiness, is clashed out of emptiness, or becomes filled.
Is Useful Line entering tomb always bad?
Not necessarily.
When asking about fast progress, entering tomb often means it is not easy to move.
But when asking about storage, savings, real estate, or long-term accumulation, entering tomb is not necessarily bad.
Is combination always good?
No.
Combination may represent cooperation, but it may also mean being held, delayed, or constrained.
Is clash always bad?
No.
Clash may break, but it may also open.
The key is whether the clashed line itself has strength, and whether what is activated is favorable or unfavorable.
Can timing be precise to a certain day?
Sometimes it can be attempted, but the difficulty is higher.
Beginners should first learn to judge trend and obstruction before studying fine timing.

26. Course 4 Summary
At this point, Course 4: Liu Yao Foundations is complete.
This course includes:
Chapter 01: What Is Liu Yao?
Chapter 02: How to Cast and Arrange a Liu Yao Hexagram
Chapter 03: Shi, Ying, and Useful God
Chapter 04: Six Relatives and Six Spirits
Chapter 05: Movement, Strength, and TimingThese five chapters establish the foundational learning path of Liu Yao:
- First understand what Liu Yao is;
- Then learn how to cast and arrange the hexagram;
- Then master Self, Other, and Useful Line;
- Then understand Six Relatives and Six Spirits;
- Finally learn movement and stillness, strength and weakness, and timing.
The focus of Liu Yao is not memorizing fixed statements, but building structural judgment ability.
It first asks:
- Who represents oneself;
- Who represents the other party;
- Which line represents the matter being asked about;
- Whether the matter has strength;
- Whether there is movement;
- Whether it is generated, supported, or controlled;
- Whether it is empty, entering tomb, held by combination, or clashed;
- When change may happen.
The real value of Liu Yao is to break a specific question into subject, object, core matter, strength state, and time change, helping people understand real choices more clearly.
27. Preview of the Next Course
Next course:
Chapter 01:
The next course will enter the Zi Wei Dou Shu system:
- What Zi Wei Dou Shu is;
- How Zi Wei Dou Shu differs from BaZi;
- What the twelve palaces represent;
- Why Life Palace and Body Palace matter;
- How to understand major stars such as Zi Wei, Tian Fu, Tai Yang, and Tai Yin;
- How the Four Transformations affect chart changes;
- How Zi Wei Dou Shu can be used to analyze personality, career, wealth, relationships, and life stages.
After completing the next course, readers will understand:
BaZi places more emphasis on the time-based stem-branch structure, while Zi Wei Dou Shu places more emphasis on palaces, stars, and the distribution of life fields. It is another important Chinese metaphysics system for understanding life structure.
