TL;DR: The Quan Quỷ line is the line whose element controls the element of the palace containing the hexagram, and it carries two meanings depending on the question: Quan means career, position, superior, agency, or husband when a woman asks; Quy means disaster, anxiety, theft, obstruction. There is no fixed answer such as Quan Quỷ moving is good or bad; you must consider who asks, what they ask, whether the line is strong or weak, and whether Tử Tôn appears to control it.
What is the Quan Quỷ line and why does it carry two names?
The Quan Quỷ line is the line whose element controls the element of the palace containing the hexagram. For example, if the hexagram belongs to the Can palace of Metal, then the Quan Quỷ line of that palace carries Fire, because Fire controls Metal. This determination lies in the core calculation of the nap jia system: each palace has one element, and among the six lines of the hexagram, the line whose element controls the palace element is called the Quan Quỷ line of that palace.
The name combines two words because this line serves two roles depending on context. The word Quan refers to things belonging to power, position, superior, agency, and when a woman asks, Quan also means husband or the man in a relationship. The word Quy refers to things that cause pressure, anxiety, disaster, theft, obstruction. The book Bo Phệ Chính Tông by Vương Duy Đức says in essence: the noble use the Quan line to discuss Quan tinh, while the common people take Quy as harm. That is, the same line, its reading depends on the asker and the question, not that the line itself is fixed as good or bad.
Why is Quan Quỷ the line controlling the palace element, and what does that indicate?
The rule of taking the line that controls the palace element as Quan Quỷ comes from how the six relatives are assigned in nap jia. Each palace has one ruling element, and the six relatives are derived by generating and controlling relationships with that palace element: the line that generates the palace is Phụ Mẫu, the line of the same element as the palace is Huynh Đệ, the line generated by the palace is Tử Tôn, the line controlled by the palace is Thê Tài, and the line that controls the palace is Quan Quỷ. Thus Quan Quỷ is the only line standing in the position of controlling back against the root of the hexagram, so it naturally carries opposition, pressure, binding. That is also why this line is both authority and disaster: both are things pressing on the asker.
It is necessary to distinguish Quan Quỷ from the other lines. Phụ Mẫu is the line that generates the palace, often documents, papers, parents, protection. Tử Tôn is the line generated by the palace, often children, relief, and especially the line that can control Quan Quỷ. Thê Tài is the line controlled by the palace, often money, wife, property. Huynh Đệ is the line of the same element as the palace, often siblings, friends, competitors. Because Tử Tôn controls Quan Quỷ, in many situations the appearance of Tử Tôn completely changes the meaning of Quan Quỷ.
Table of Quan Quỷ lines by the eight palaces
The table below is built from the core calculation: each palace has one element, the Quan Quỷ line of that palace carries the element that controls the palace element, and the branches carrying that element are those that can appear at the Quan Quỷ position in hexagrams of that palace.
| Palace | Palace element | Element of Quan Quỷ line | Branches carrying that element |
|---|---|---|---|
| Can | Metal | Fire | Ty, Ngo |
| Kham | Water | Earth | Thin, Tuat, Suu, Mui |
| Can | Earth | Wood | Dan, Mao |
| Chan | Wood | Metal | Than, Dau |
| Ton | Wood | Metal | Than, Dau |
| Ly | Fire | Water | Ty, Hoi |
| Khon | Earth | Wood | Dan, Mao |
| Doai | Metal | Fire | Ty, Ngo |
This table only shows what element the Quan Quỷ line of each palace carries and which branches it can fall into. To know in a specific hexagram which line number the Quan Quỷ line is at and what branch it carries, you need to cast the hexagram with a nap jia tool such as LapQueLucHao and then compare with the table above. The table cannot replace casting the hexagram.
When to read as Quan, when to read as Quy?
The short answer: read as Quan when the question belongs to career, position, exams, superior, agency, or when a woman asks about her husband and the man. Read as Quy when the question belongs to safety, anxiety, disaster, litigation, theft, or when this line plays the role of obstructing the pursued goal.
The book Tăng San Bốc Dịch by Dã Hạc lao nhan, in the section on seeking career, says in essence: if you get Quan tinh strong holding the Self line, or the day and month and moving line make Quan tinh generate and combine with the Self line, then seeking fame is easy as taking something from your pocket. Conversely, if you meet Tử Tôn holding the Self line or Tử Tôn moving in the hexagram, then seeking to pass exams or seeking promotion is hard to achieve. Thus the Tăng San policy clearly separates the two faces: Quan Quỷ is what is needed when seeking fame, but it is what is destroyed by Tử Tôn when seeking fame, and conversely Tử Tôn is what is desirable when needing to suppress disaster.
The phu for divining the I Ching circulated in Lục Hào circles also records in that direction. With the Quy line holding the Self, the phu says in essence: matters are hard to be peaceful, divining for oneself if not illness then entanglement in trouble, divining for wealth then worry of loss, but for seeking career one is glad when this line is in position and in power. The same line, the same at the Self, yet the conclusion reverses completely according to the question. This is the core point of reading Quan Quỷ.
What does Quan Quỷ holding the Self say when asking about career?
When asking about career, position, exams, Quan Quỷ holding the Self is often seen as a sign that the asker is directly tied to that matter: currently holding a related position, very concerned, or personally involved. If this Quan Quỷ line is also strongly generated and supported by Phụ Mẫu, the common reading direction is the possibility of being valued or restored to a higher position, with only the timing left.
Conversely, if Quan Quỷ holds the Self but is heavily controlled, especially by Huynh Đệ or Tử Tôn, then the path of advancement meets obstacles. Huynh Đệ symbolizes competition, opponents; Tử Tôn symbolizes breaking in, obstructing official matters. The book Tăng San Bốc Dịch emphasizes exactly this point when saying Tử Tôn holds the Self or Tử Tôn moves then seeking promotion is hard to achieve. However, note: this is the common reading direction, not an absolute rule, because you still must consider day and month, moving lines, void, month break, and combine clash relationships.
One point where books are not fully consistent: some books hold that Quan Quỷ holding the Self is always a sign of pressure, even when asking about career; other books hold that in seeking office, Quan Quỷ holding the Self is a favorable condition. The book Bo Phệ Chính Tông leans toward reading according to the asker, while some other books read Quan Quỷ moving as bad regardless of the question. This article follows the convention of Bo Phệ Chính Tông: the meaning of Quan Quỷ depends on the asker and the question.
What does Quan Quỷ holding the Self say when asking about safety?
When asking about safety, anxiety, litigation, theft, Quan Quỷ holding the Self is often read according to the Quy face: the asker is under heavy pressure, persistently worried, or entangled in a difficult situation. The phu for divining the I Ching says in essence: Quy holding the Self then matters are hard to be calm, divining for wealth then worry of loss, if entering the tomb then stagnation and sorrow, meeting day and month that clash open the tomb then disaster turns to joy.
Here it is necessary to distinguish two situations. First, Quan Quỷ holds the Self and is strong, and is generated and supported by Thê Tài, then the pressure has a clear source, possibly a superior, possibly a partner, possibly a specific force. Second, Quan Quỷ holds the Self and is weak, and meets inauspicious stars or is controlled, then the pressure is more vague, likely inner worry rather than external threat. This second reading is close to the spirit of Bo Phệ Chính Tông when distinguishing Quan tinh and Quy harm according to the asker.
It must be said clearly: this article does not use the Quan Quỷ line to diagnose illness. In traditional Lục Hào there is a branch of illness discussion based on Quan Quỷ, but that is a separate field with its own rules and is not within the scope of this article. Readers with health needs should seek professional medical advice rather than rely on hexagrams.
Why is Tử Tôn the nemesis of Quan Quỷ?
Tử Tôn is the line generated by the palace element, and in the five-element relationship, this line can control Quan Quỷ. According to the book Lục Nhâm, volume 1, introductory section, it says in essence: when divining harmful matters such as illness, official trouble, then Tử Tôn is needed, because Tử Tôn can control Quan Quỷ, that is, the line causing disaster, so Tử Tôn is called the saving spirit, also the Phuc Duc line. However, when divining about official position or seeking office and meeting Tử Tôn, that is an unfortunate point, because the Quan line has been controlled away by Tử Tôn.
This means: Tử Tôn is not fixed good or bad. It is good when the goal is to extinguish disaster, and it is unfavorable when the goal is to keep or attain authority. The book Lục Nhâm also adds: if asking about livelihood and business and meeting Tử Tôn then it is not good, because Tử Tôn drains one's own energy, so it is also called the Thoat Khi line. Thus Tử Tôn has three roles: saving spirit when meeting disaster, breaking office when seeking position, and draining energy when seeking wealth. The same line, three readings, depending on the question.
Where schools and books are not consistent
There are at least three differences between books when discussing Quan Quỷ.
First, about the original meaning. Bo Phệ Chính Tông advocates that the meaning of Quan Quỷ depends on the asker: the noble use the Quan line as Quan tinh, the common people take Quy as harm. Some other books read all moving Quan Quỷ as bad, regardless of the question.
Second, about the role of Tử Tôn. The book Lục Nhâm emphasizes Tử Tôn as saving spirit when meeting disaster, but also as an unfavorable point when seeking office. Some books only say Tử Tôn controls Quan Quỷ without separating these two faces, leading to oversimplified conclusions.
Third, about the threshold of strength and weakness. The phu for divining the I Ching says in essence that Quan Quỷ in a strong position then seeking office succeeds, while Quan Quỷ weak then disaster strikes oneself. But which threshold is called strong, which is called weak, each book sets differently, and in practice one must also combine with day and month, moving lines, void, month break. Therefore one should not apply a rigid formula to all cases.
Practical approach
When encountering a Quan Quỷ line in a hexagram, the usual reading sequence is: determine who the asker is and what they ask; determine which line the Quan Quỷ line is at, what branch, what element; see whether it is strong or weak according to day and month; see whether it is void, month-broken, entering the tomb; see whether it is controlled by Tử Tôn or Huynh Đệ; see whether it is generated and supported by Thê Tài or Phụ Mẫu. Only then give a judgment, and the judgment should clearly state which convention it follows.
An important note: do not assert absolute fortune or misfortune. The same Quan Quỷ holding the Self, when asking about career can be a favorable sign, when asking about safety can be a sign of pressure, and both are only tendencies, not predetermined results. The books Tăng San Bốc Dịch, Bo Phệ Chính Tông, and Lục Nhâm all emphasize examining the whole hexagram, not taking one line as the final conclusion.
