TL;DR: Phong Thủy Hoán (渙) is hexagram 59 of the 64 I Ching hexagrams, with the inner trigram Khảm (water) and the outer trigram Tốn (wind), symbolizing wind blowing over water and causing waves to scatter. The hexagram text reads: 渙:亨,王假有廟,利涉大川,利貞。 The six line texts describe six ways of responding when things disperse. Nhật Nguyệt's suggestion: in work and relationships, one should recognize cracks early, find a point of support, and be ready to restructure.
What is the Phong Thủy Hoán hexagram in the I Ching?
Phong Thủy Hoán (風水渙), usually shortened to Hoan (渙), is hexagram number 59 among the 64 hexagrams of the I Ching. The hexagram consists of the inner trigram (lower trigram) Kan ☵ symbolizing water, and the outer trigram (upper trigram) Ton ☴ symbolizing wind. The image of the hexagram is wind moving over the surface of water: when water meets wind it breaks apart into waves, hence it is called Hoan, meaning to disperse, to scatter, to separate.
The hexagram has three yang lines and three yin lines. It belongs to the Wood element, its time is one of smooth flow, and its opposite hexagram (the reverse hexagram) is Lôi Hỏa Phong (hexagram 55). A distinction is needed: Hoan is the hexagram of dispersal, while Phong is the hexagram of fullness and great flourishing. The two hexagrams stand near each other in the sequence of 64 and illuminate one another.
It should be made clear from the outset: the "core text" portion of the I Ching consists of the hexagram statements (also called the Thoan tu) and the line statements, which tradition attributes to Văn Vương and Chu Công; modern scholarship (Edward Shaughnessy; Redmond and Hon, Teaching the I Ching, 2014) places this portion around the late 9th century BCE, in the Western Zhou era, and does not treat that attribution as proven. As for the Thoan truyen, Tuong truyen, He tu, and Tự Quái, these are later commentaries, not core text. This article names each layer accordingly. In addition, the Khổng Minh Thần Toán poem card is the card text of a different book, not a line statement of the Zhou Yi, so it is not mixed in here.
Why does the Hoan hexagram come after the Doai hexagram (number 58)?
According to the Tự Quái truyen, which explains the order of the 64 hexagrams, after joy there must come a time of dispersal, so after the Doai hexagram (number 58, joy) comes the Hoan hexagram (number 59, dispersal). The word Hoan here carries the meaning of separation, that is, scattering apart. This is one sentence in the Tự Quái truyen, a later commentary, not core text.
This line of reasoning follows the familiar thread of the Tự Quái: each hexagram follows the previous one according to a rule of life. When joy reaches its extreme it easily gives rise to boredom, dissolution, or bursting apart. In the current way of reading the I Ching, the order of hexagrams is understood as the pair Doai and Hoan having a causal relationship with each other.
What does the hexagram statement of Phong Thủy Hoán say?
The hexagram statement (Thoan tu) of the Hoan hexagram reads:
渙:亨,王假有廟,利涉大川,利貞。
Hoan: Hanh, vuong cach huu mieu, loi thiep dai xuyen, loi trinh.
Meaning: Hoan is dispersal, is scattering, smooth flow. The king comes to the ancestral temple, it is fitting to cross the great river, to hold firm brings benefit.
The Thoan truyen writes: 渙,亨。剛來而不窮,柔得位乎外而上同。王假有廟,王乃在中也。利涉大川,乘木有功也。
Translation: Hoan is smooth flow. The firm comes and is not exhausted, the yielding obtains its place outside and ascends together. The king comes to the temple, the king is within it. It is fitting to cross the great river, by riding wood there is merit.
Wang Bi comments on the Thoan truyen: "王乃在乎渙然之中,故至有廟也。" (The king is within the place of dispersal, hence he comes to the temple.) And "乘木即涉難也。木者專所以涉川也。涉難而常用渙道,必有功也。" (Riding wood is crossing difficulty. Wood is the thing specifically used to cross rivers. Crossing difficulty while constantly using the way of dispersal will surely have merit.)
Chu Hy (Chu Dịch bản nghĩa) comments: "渙散也為卦下坎上巽風行水上離披解散之象故為渙...其占可亨又以祖考之精神既散故王者當至於廟以聚之又以巽木坎水舟楫之象故利涉大川其曰利貞則占者之深戒也." (Hoan is dispersal. The hexagram is Kan below and Ton above, wind moving over water, the image of scattering and breaking apart, hence it is Hoan... Its divination can be smooth flow. Also, because the spirit of the ancestors has scattered, the king must come to the temple to gather it. Also, because Ton wood and Kan water are the image of boats and oars, it is fitting to cross the great river. Saying it is fitting to hold firm is a deep warning for the diviner.)
What is noteworthy is that the phrase "the king comes to the temple" (王假有廟) appears almost intact in the hexagram statement of the Tuy hexagram (number 45, Thủy Địa Tụy), the hexagram of gathering. This is a point many scholars emphasize: both in times of gathering and in times of dispersal there is need of a place to return to. When people are gathered together, the temple is what keeps that gathering on its axis. When people are scattering, the temple is needed all the more, because it is the point that draws people's hearts back.
The phrase "it is fitting to cross the great river" (利涉大川) also appears in many other hexagrams, and here it means daring to do great things while everything is coming apart. "It is fitting to hold firm" (利貞) is a reminder: amid dispersal, whoever keeps to the central axis will not be swept away.
Some books and websites judge the hexagram in terms of absolute fortune or misfortune, for instance calling the Hoan hexagram an "inauspicious hexagram" with the name Cach ha vong kim (gazing at gold across the river), meaning wasted effort. Yet in the common way of interpreting it, the disintegration here is not necessarily negative. These two readings differ, and this article does not choose one side: the hexagram statement itself says both "smooth flow" and "it is fitting to hold firm," so both faces have a basis in the classic text.
The image statement: wind moving over water and the establishing of temples
The Great Image (Tuong truyen) of the Hoan hexagram reads:
風行水上,渙;先王以享于帝立廟。
Phong hanh thuy thuong, Hoan; tien vuong di huong vu de lap mieu.
Meaning: wind blows over the surface of the water, that is the image of the Hoan hexagram. The kings of former times accordingly sacrificed to the Supreme Lord and established temples for worship.
This image has two layers. The first is the layer of image: wind blowing over water makes the waves scatter, but the water is still water. Dispersal on the surface is not loss of the root. The second is the layer of the former kings' action: establishing temples for worship is precisely creating a point of spiritual convergence amid the scattering of everything.
The book Phong thuy cổ đại Trung Quốc: lý luận và thực tiễn, volume 2, has a passage discussing the image of wind moving over water of this hexagram. The book recounts the explanation by Quách Phác of the Jin era regarding Phong Thủy: the ancients gathered qi, not letting it scatter, but making it gather; qi, when it meets wind, is blown apart, and when it meets water, stops and gathers into a mass; holding qi in this way is what is called Phong Thủy. The book also notes that in the Zhou Yi there are three hexagrams related to the pair wind and water: Ton is wind, Kan is water, Ton above and Kan below combine into the Hoan hexagram, and the basic meaning of the Hoan hexagram is wind moving over the surface of water. According to this book, traditional Phong Thủy takes the direction of water flow and the direction of wind in the terrain and landscape as its basis, aiming toward the auspicious and avoiding the inauspicious, while eliminating calamity. It should be noted: this is how one phong thuy book uses the image of the Hoan hexagram, not the core text of the I Ching.
The six line statements of the Hoan hexagram and plain-language explanations
The six lines of the Hoan hexagram describe six ways of acting when facing dispersal. Read from the bottom up: the first line is the lowest, the top line is the highest. Line names and line positions follow the Chinese text and Sino-Vietnamese reading.
| Line | Original Chinese text | Sino-Vietnamese reading | Common meaning |
|---|---|---|---|
| So luc (line 1) | 用拯馬壯,吉 | Dung chung ma trang, cat | Using a strong horse to rescue, auspicious |
| Cuu nhi (line 2) | 渙奔其机,悔亡 | Hoan bon ky ky, hoi vong | When scattering, run to one's support, regret disappears |
| Luc tam (line 3) | 渙其躬,无悔 | Hoan ky cung, vo hoi | Dispersing one's own selfishness, no regret |
| Luc tu (line 4) | 渙其群,元吉。渙有丘,匪夷所思 | Hoan ky quan, nguyen cat. Hoan huu khau, phi di so tu | Dispersing one's own faction is greatly auspicious. Dispersing then gathering into a mound, that is what ordinary people do not think of |
| Cuu ngu (line 5) | 渙汗其大號,渙王居,无咎 | Hoan han ky dai hao, hoan vuong cu, vo cuu | Issuing a great proclamation like sweat breaking out, dispersing the king's stores, no harm |
| Thuong cuu (line 6) | 渙其血,去逖出,无咎 | Hoan ky huyet, khu dich xuat, vo cuu | Dispersing the blood, departing far from danger, no harm |
Line 1: rescuing right when dispersal begins
Line statement: 初六:用拯馬壯,吉,悔亡。 (So luc: Dung chung ma trang, cat, hoi vong.)
Small Image: 初六之吉,順也。 (So luc chi cat, thuan da.)
Wang Bi comments: "渙,散也。處散之初,乖散未甚,故可以遊行,得其志而違於難也,不在危劇而後乃逃竄,故曰「用拯馬壯,吉」。" (Hoan is dispersal. At the beginning of the time of dispersal, the scattering is not yet deep, so one can move about, achieve one's aim and avoid the difficulty, not fleeing only after it has become critical, hence it says "using a strong horse to rescue, auspicious.")
Chu Hy comments: "居卦之初渙之始也始渙而拯之為力既易又有壮馬其吉可知初六非有濟渙之才但能順乎九二故其象占如此." (Being at the beginning of the hexagram, it is the start of dispersal. Rescuing right when dispersal begins, the effort is still easy, and there is also a strong horse, so the auspiciousness can be known. So luc does not have the talent to rescue dispersal, but can only follow Cuu nhi, hence the image and divination are like this.)
In Nhật Nguyệt's understanding: the line statement says to use the greatest strength available to rescue the situation, as if having a strong horse to help travel a long road. This line is yin and yielding, lacking in talent and not strong enough, but above it there is line 2, yang and firm and centrally placed, to which it can entrust itself and rely on, hence the auspiciousness. Recognizing dispersal when it has just begun means it can still be saved; leaving it too late means it is lost.
Nhật Nguyệt's suggestion: if a job or project is just showing signs of cracking, deal with it early, relying on strong allies; do not delay until it is hard to save.
Line 2: when scattering, run to one's support
Line statement: 九二:渙奔其机,悔亡。 (Cuu nhi: Hoan bon ky ky, hoi vong.)
Small Image: 渙奔其机,得愿也。 (Hoan bon ky ky, dac nguyen da.)
Wang Bi comments: "機,承物者也,謂初也。二俱無應,與初相得,而初得散道,離散而奔,得其所安,故「悔亡」也。" (Ky is the thing that supports, referring to the first line. Both lines have no correspondence, and get along with the first, and the first obtains the way of dispersal; separating and scattering, it runs and finds its place of rest, hence "regret disappears.")
Chu Hy comments: "机音几○九而居二宜有悔也然當渙之時來而不窮能亡其悔者也故其象占如此蓋九奔而二机也." (Ky is pronounced ki. Nine dwelling in two should have regret, but meeting the time of dispersal, coming and not being exhausted, it can make its regret disappear, hence the image and divination are like this. Nine is running, two is the support.)
In Nhật Nguyệt's understanding: Cuu nhi is a yang and firm line, centrally placed. The line statement says that running to one's support makes regret disappear. This line, yang and firm, can help line 1, and what should be done is to rely on line 1 as a seat, supporting each other in a time of wandering. "Support" here depends on circumstances: it may be family, it may be a core skill, it may be the person one trusts most. Do not try to hold everything, keep what is most important.
Nhật Nguyệt's suggestion: in love, if the relationship is cracking, find a shared point of support; at work, focus on core strengths instead of spreading thin.
Line 3: letting go of the private self
Line statement: 六三:渙其躬,无悔。 (Luc tam: Hoan ky cung, vo hoi.)
Small Image: 渙其躬,志在外也。 (Hoan ky cung, chi tai ngoai da.)
Wang Bi comments: "渙之為義,內險而外安者也。散躬志外,不固所守,與剛合志,故得無悔也。" (The meaning of Hoan is danger within and safety without. Dispersing the self and setting one's will outward, not holding firmly to what one guards, joining one's will with the firm, hence one obtains no regret.)
Chu Hy comments: "陰柔而不中正有私於已之象也然居得陽位志在濟時能散其私以得无悔故其占如此大率此上四爻皆因渙以濟渙者也." (Yin and yielding and not central and correct, it has the image of being partial to oneself. But dwelling in a yang position, its will is set on rescuing the time, and it can disperse its private interest to obtain no regret, hence the divination is like this. Broadly, the upper four lines all use dispersal to rescue dispersal.)
In Nhật Nguyệt's understanding: Luc tam is a yin and yielding line, neither central nor correct. The line statement says that dispersing one's own private interest brings no regret. The word "cung" in "hoan ky cung" refers to a person hunched and curled up like a bent bow, that is, a selfish person, contracting like the shape of a bow. "Hoan ky cung" is reforming that selfishness, which is also the root that gives rise to division and scattering. This line is for someone torn between personal interest and the common interest.
Nhật Nguyệt's suggestion: if you are in conflict between the self and the collective, set aside the private for a time and aim toward the common goal; this can help reduce tension.
Line 4: breaking up private factions to gather on a larger scale
Line statement: 六四:渙其群,元吉。渙有丘,匪夷所思。 (Luc tu: Hoan ky quan, nguyen cat. Hoan huu khau, phi di so tu.)
Small Image: 渙其群,元吉;光大也。 (Hoan ky quan, nguyen cat; quang dai da.)
Wang Bi comments: "逾乎險難,得位體巽,與五合志,內掌機密,外宣化命者也,故能散群之險,以光其道。然處於卑順,不可自專,而為散之任,猶有丘虛匪夷之慮,雖得元吉,所思不可忘也。" (Passing beyond danger and difficulty, obtaining its place and embodying Ton, joining its will with the fifth line, within holding secrets, without proclaiming transformative orders, hence it can disperse the danger of factions and make its way shine. But being in a low and yielding position, it cannot act on its own authority, and bearing the task of dispersal, it still has worries about empty mounds and extraordinary things; though it obtains great auspiciousness, what it thinks of cannot be forgotten.)
Chu Hy comments: "居隂得正上承九五當濟渙之任者也下无應與為能散其朋黨之象占者如是則大善而吉又言能散其小羣以成大羣使所散者聚而若丘則非常人思慮之所及也." (Dwelling in yin and obtaining correctness, above it supports Cuu ngu, and it bears the task of rescuing dispersal. Below it has no correspondence, which is the image of being able to disperse its factions. If the diviner is like this, then it is greatly good and auspicious. It also says it can disperse its small groups to form a large group, causing what is dispersed to gather like a mound, which is not what ordinary people's thoughts can reach.)
In Nhật Nguyệt's understanding: Luc tu is the line with the best statement in the hexagram. The line statement says that dissolving one's factions is very auspicious, because doing so is dissolving the small to gather the large into a mound, something ordinary people do not think of. This line is yin and yielding, compliant, helping line 5, which is both firm and centrally placed, like a great minister helping the king dissolve factions so as to gather the whole people in unity. This is where the Hoan hexagram speaks directly about breaking the old to build the new.
Nhật Nguyệt's suggestion: in leadership, if you see small groups dividing, find a way to unite them under a larger common goal; this can bring good results.
Line 5: the leader issuing orders amid dispersal
Line statement: 九五:渙汗其大號,渙王居,无咎。 (Cuu ngu: Hoan han ky dai hao, hoan vuong cu, vo cuu.)
Small Image: 王居无咎,正位也。 (Vuong cu vo cuu, chinh vi da.)
Wang Bi comments: "處尊履正,居巽之中,散汗大號,以蕩險阨者也。為渙之主,唯王居之,乃得無咎也。" (Dwelling in honor and treading correctness, being in the center of Ton, issuing a great proclamation like sweat, to sweep away danger and obstruction. As the master of Hoan, only the king dwelling in it obtains no harm.)
Chu Hy comments: "陽剛中正以居尊位當渙之時能散其號令與其居積則可以濟渙而无咎矣故其象占如此九五巽體有號令之象汗謂如汗之出而不反也渙王居如陸贄所謂散小儲而成大儲之意." (Yang and firm, central and correct, dwelling in the honored position, meeting the time of dispersal, it can issue its orders and disperse its accumulated stores, and so can rescue dispersal and have no harm, hence the image and divination are like this. Cuu ngu, being of the Ton body, has the image of orders. Sweat means like sweat that comes out and does not return. "Hoan vuong cu" is like what Lục Chí called dispersing the small store to form the great store.)
In Nhật Nguyệt's understanding: Cuu ngu is the line of the leader. "Issuing a great proclamation like sweat breaking out" means that once an order is issued it cannot be taken back, just as sweat that has broken out cannot be drawn back into the skin. The phrase "hoan vuong cu" means the king should disperse wealth to gather the people, just as line 4 dissolves factions to gather the people, both being good policy in a time of scattering. Phan Bội Châu's rendering of the five characters "hoan han ky dai hieu" is to proclaim orders everywhere. Nhật Nguyệt's suggestion: whoever is in a position of management or leadership, the time of dispersal is the time to give, not to hold tight.
Nhật Nguyệt's suggestion: in management, boldly issue clear policies and share resources to win people's hearts; avoid clutching everything tightly.
Line 6: escaping danger
Line statement: 上九:渙其血,去逖出,无咎。 (Thuong cuu: Hoan ky huyet, khu dich xuat, vo cuu.)
Small Image: 渙其血,遠害也。 (Hoan ky huyet, vien hai da.)
Wang Bi comments: "逖,遠也。最遠於害,不近侵克,散其憂傷,遠出者也。散患於遠害之地,誰將咎之哉!" (Dich is far. Farthest from harm, not near encroachment, dispersing its sorrow and injury, going far out. Dispersing trouble in a place far from harm, who will blame it!)
Chu Hy comments: "去起吕反○上九以陽居渙極能出乎渙故其象占如此血謂傷害逖當作惕與小畜六四同言渙其血則去渙其惕則出也." (Khu is pronounced khu. Thuong cuu, with yang dwelling at the extreme of Hoan, can emerge from dispersal, hence the image and divination are like this. Blood means injury and harm. Dich should be read as tich, the same as Tiểu Súc line four. It says dispersing its blood means departing, dispersing its fear means emerging.)
In Nhật Nguyệt's understanding: Thuong cuu is a yang line at the end of the time of scattering. The line statement says that dispersing the blood and departing far from danger brings no harm. This line is at the end of the time of scattering, when the bad omen is about to end, and it also has the talent of yang firmness and is supported by line 3, and so it succeeds, removing the wound of scattering and escaping the state of fear. "Dispersing the blood" here means the pooled blood disperses, that is, the danger has been resolved. This line is for someone in a relationship or environment of high risk: leaving at the right time brings no harm.
Nhật Nguyệt's suggestion: if you find an environment or relationship toxic, find a way to move away to protect yourself; this can help avoid loss.
How should one understand drawing the Hoan hexagram when asking about work?
Drawing the Hoan hexagram when asking about work usually indicates a phase of restructuring: work may be in flux, there may be a need to change how things operate or to dissolve an ineffective group. The hexagram does not assert success or failure, but suggests looking to flexibility and the ability to adapt.
In Nhật Nguyệt's understanding: in a career, hexagram number 59 leans toward erasing the old, dissolving ineffective groups, or changing how things operate. Another line of interpretation holds that the hexagram indicates only a period of scattering, full of difficulty and with little that is favorable, with people's hearts unsettled and finances difficult, requiring one to seek a living far from home; but the positive point is that going far or changing careers can be more favorable.
Nhật Nguyệt's suggestion: if you are considering changing jobs, examine it carefully; the opportunity may come from restructuring or a change of direction. Avoid hasty decisions.
How should one understand drawing the Hoan hexagram when asking about love?
In matters of love, drawing the Hoan hexagram usually signals that the relationship is going through a phase of dispersal, or needs to be "dispersed" to be renewed. The two people may need some distance to look again, or need to break old habits that are freezing the relationship. The hexagram does not say that breaking up is bad, nor that staying is good.
In Nhật Nguyệt's understanding: if there is a crack, find a way to have an open dialogue, and it may be necessary to change how you interact. Do not weigh gain and loss so heavily, but focus on understanding.
Nhật Nguyệt's suggestion: if the relationship is tense, temporarily create distance to look again; this can help heal or lead to a wise decision.
How does the Hoan hexagram differ from the Phong hexagram (number 55)?
Phong (number 55, Lôi Hỏa Phong) is the opposite hexagram of Hoan by the reverse-hexagram method, and is the hexagram of fullness and great flourishing. The two hexagrams illuminate each other: Phong speaks of the time when everything is already full, while Hoan speaks of the time when everything is coming apart. Placed side by side, we see a familiar rule in the I Ching: when full it must wane, when gathered it must scatter, and conversely, when scattered there must come a time of gathering. This matches the thread of the Tự Quái mentioned above: after joy comes dispersal.
The structure of the Phong Thủy Hoán hexagram in one table
| Item | Value |
|---|---|
| Order number in the Zhou Yi | 59 |
| Chinese character name | 渙 |
| Upper trigram | Ton (Wind) |
| Lower trigram | Kan (Water) |
| Six lines, from top to bottom | yang, yang, yin, yin, yang, yin |
| Nuclear hexagram | Sơn Lôi Di (hexagram number 27) |
| Reversed hexagram | Lôi Hỏa Phong (hexagram number 55) |
| Opposite hexagram | Thủy Trạch Tiết (hexagram number 60) |
Where do the six lines of the Phong Thủy Hoán hexagram stand, and which hexagram does each line change into when it moves?
The table reads from the first line (bottom) up to the top line. Line names combine position and nature: yang is called Cuu, yin is called Luc. The last column is the changed hexagram when ONLY that line moves, calculated by the same method that the Nhật Nguyệt divination tool uses.
| Line | Name | Nature | Correct position | Central | Correspondence | When moving, changes into |
|---|---|---|---|---|---|---|
| 1 | Sơ Lục | yin | no | no | with line 4, no correspondence | Phong Trạch Trung Phu (hexagram number 61) |
| 2 | Cửu Nhị | yang | no | yes | with line 5, no correspondence | Phong Địa Quán (hexagram number 20) |
| 3 | Lục Tam | yin | no | no | with line 6, has correspondence | Thuần Tốn (hexagram number 57) |
| 4 | Lục Tứ | yin | yes | no | with line 1, no correspondence | Thiên Thủy Tụng (hexagram number 6) |
| 5 | Cửu Ngũ | yang | yes | yes | with line 2, no correspondence | Sơn Thủy Mông (hexagram number 4) |
| 6 | Thượng Cửu | yang | no | no | with line 3, has correspondence | Thuần Khảm (hexagram number 29) |
It should be repeated that the line statements of the Hoan hexagram carry the social norms of ancient times, such as the king dispersing wealth to gather the people, or the great minister helping the king eliminate factions. That is the historical context of a feudal society, not advice to be applied directly to life today. Modern readers can draw out the general principle, while the specific application depends on circumstances.
Finally, the schools of hexagram interpretation do not agree with one another on whether the Hoan hexagram is auspicious or inauspicious. In the common understanding, this hexagram emphasizes the side of smooth flow and restructuring, but there is also a way of classifying it as inauspicious and linking it to the name Cach ha vong kim. Both readings have a basis in the classic text and in the tradition of hexagram interpretation, so the reader should know which convention they are following.
