TL;DR: The Thái Tuế ring is a ring of 12 secondary stars in Tử Vi (Vietnamese astrology), beginning with the star Thái Tuế (Grand Duke) placed in the palace that coincides with the Earthly Branch of the birth year, after which one star is placed clockwise in each palace in a fixed order. According to Thiên Lương, the ring divides into four triple combinations: Thái Tuế (Thái Tuế, Quan Phù, Bạch Hổ), Thiếu Dương (Thiếu Dương, Tử Phù, Phúc Đức), Thiếu Âm (Thiếu Âm, Long Đức, Trực Phù) and Tuế Phá (Tuế Phá, Tang Môn, Điếu Khách). The article sets out how the ring is placed and how it is understood across three Vietnamese Tử Vi books: Tử Vi đẩu số tân biên, Tử Vi áo bí biện chứng học and Tử Vi nghiệm lý toàn thư; all of them consider this ring together with the whole chart, and none treats it as a fixed outcome.
What Is the Thái Tuế Circle in Tử Vi?
The Thái Tuế circle is one of the rings of secondary stars on a Tử Vi chart, made up of 12 stars placed consecutively across the 12 Địa Chi palaces in a fixed order, beginning with Thái Tuế. This article presents the placement and the readings of Vietnamese Tử Vi, based on three books: Tử Vi đẩu số tân biên by Vân Đằng Thái Thứ Lang, Tử Vi áo bí biện chứng học by Việt Viêm Tử, and Tử Vi nghiệm lý toàn thư by Thiên Lương; where the books differ, each is reported separately. Tử Vi đẩu số tân biên writes: "Trước hết phải an Thái Tuế ở cung có tên hàng Chi của năm sinh" (first place Thái Tuế in the palace named after the branch of the birth year), and then, for men and women alike, one star per palace going clockwise[1]. Tử Vi áo bí biện chứng học gives the same rule with an example: if Thái Tuế is in the Dần palace, then Thiếu Dương is in Mão, Tang Môn in Thìn, Thiếu Âm in Tỵ, Quan Phù in Ngọ, Tử Phù in Mùi, Tuế Phá in Thân, Long Đức in Dậu, Bạch Hổ in Tuất, Phúc Đức in Hợi, Điếu Khách in Tý, and Trực Phù in Sửu[3].
Why is it placed by the birth year branch? Việt Viêm Tử explains that numerologists since the early Han period knew that Thái Tuế, which he identifies with Jupiter (Mộc tinh), moves along the ecliptic through the Dần and Thân axis and completes one circuit in 12 years, and that this is why Tử Vi places Thái Tuế in the palace of the birth year[3]. This is the author's own explanation, not a verified astronomical fact.
Which Stars Make Up the Twelve of the Thái Tuế Circle?
The order of the 12 stars according to Tử Vi áo bí biện chứng học is: Thái Tuế, Thiếu Dương, Tang Môn, Thiếu Âm, Quan Phù, Tử Phù, Tuế Phá, Long Đức, Bạch Hổ, Phúc Đức, Điếu Khách, Trực Phù, the same order as in Tử Vi đẩu số tân biên. Việt Viêm Tử notes a practical point: when writing the stars onto a chart, Thiên Không is placed in the same palace as Thiếu Dương, that is, the next palace clockwise from Thái Tuế, which the book calls the palace in front, and Quán Sách is placed in the same palace as Trực Phù, the palace behind Thái Tuế[3]. Tử Vi đẩu số tân biên gives the same position for Thiên Không: it goes in the palace in front of the one holding Thái Tuế; for example, if Thái Tuế is in Mùi, Thiên Không is in Thân[1]. These two stars accompany the Thái Tuế circle but are not among its 12 stars.
On the five elements the two books differ. Tử Vi đẩu số tân biên lists Thái Tuế as Hỏa[1]. Việt Viêm Tử classifies Thái Tuế as Mộc, with the two accompanying stars Thiên Không and Quán Sách as Hỏa, and writes that calling Thái Tuế a Hỏa star is "lầm lẫn lớn" (a great mistake)[3].
The table below summarizes the 12 stars in clockwise placement order and their corresponding positions when Thái Tuế is in the Dần palace, following Việt Viêm Tử's example:
| Order | Star name | Palace when Thái Tuế is in Dần |
|---|---|---|
| 1 | Thái Tuế | Dần |
| 2 | Thiếu Dương | Mão |
| 3 | Tang Môn | Thìn |
| 4 | Thiếu Âm | Tỵ |
| 5 | Quan Phù | Ngọ |
| 6 | Tử Phù | Mùi |
| 7 | Tuế Phá | Thân |
| 8 | Long Đức | Dậu |
| 9 | Bạch Hổ | Tuất |
| 10 | Phúc Đức | Hợi |
| 11 | Điếu Khách | Tý |
| 12 | Trực Phù | Sửu |
How Is the Thái Tuế Circle Placed by Birth Year Branch?
Placing the Thái Tuế circle is fairly simple compared with other star rings, because it depends only on the birth year branch and not on yin-yang, male-female, or the cục number. The steps are:
- Determine the birth year branch (Tý, Sửu, Dần, Mão, Thìn, Tỵ, Ngọ, Mùi, Thân, Dậu, Tuất, Hợi).
- Place Thái Tuế in the palace bearing that exact branch on the chart. A person born in the year of the Mão has Thái Tuế in the Mão palace; one born in the year of the Dần has Thái Tuế in the Dần palace.
- From the Thái Tuế palace, place the remaining 11 stars clockwise, one star per palace, in the exact order given above.
One point to note is that the Thái Tuế circle on the natal chart, placed by the birth year, differs from the annual Thái Tuế circle. In its method for annual periods, Tử Vi áo bí biện chứng học places the circle again by the year under review: Thái Tuế in the palace bearing the branch of the current year, the remaining 11 stars clockwise, with Thiên Không and Quán Sách before and after Thái Tuế[3].
How Do the Three Tam Hợp Thái Tuế, Thiếu Dương, and Thiếu Âm Differ?
The 12 stars of the Thái Tuế circle divide into four groups; the three stars of each group stand four palaces apart, so they are always in tam hợp with one another. This grouping comes from Thiên Lương in Tử Vi nghiệm lý toàn thư, who calls them the four patterns Thái Tuế, Tuế Phá, Thiếu Dương, and Thiếu Âm[2].
Tam hợp Thái Tuế consists of Thái Tuế, Quan Phù, and Bạch Hổ. Thiên Lương calls this the main stance of the birth year, explaining that even if the Mệnh palace falls elsewhere, Thái Tuế still sits in the palace bearing the birth year branch. He regards this tam hợp as the person's home ground, linked to luck, prosperity, and authority. Also according to him, Thái Tuế is dignified by the pair Long Trì and Phượng Các: for yang birth years only Long Trì lies inside the Thái Tuế tam hợp, while yin birth years have both; and because Thái Tuế is such a favorable stance, Thiên Không has to stand beside it as a restraint[2].
Tam hợp Thiếu Dương consists of Thiếu Dương, Tử Phù, and Phúc Đức. Thiên Lương describes this as a stance contrary to the yin-yang polarity of the age, but along the way Thiếu Dương is often favored in states of sinh nhập or khắc xuất, so the person easily grows careless and overreaches; hence Đào Hoa, Thiên Không, and Kiếp Sát stand in the way as reminders[2].
Tam hợp Thiếu Âm consists of Thiếu Âm, Long Đức, and Trực Phù. Thiên Lương remarks that Thiếu Âm in the Long Đức Trực Phù stance usually loses out in every way, so Hồng Loan and Thiên Hỷ share the task of offering some consolation. Also according to him, both Hồng Loan and Thiên Hỷ stand in stances contrary to the yin-yang polarity of the age and are symmetrical to each other[2].
The Tuế Phá group consists of Tuế Phá, Tang Môn, and Điếu Khách. Thiên Lương calls this the Tuế Phá tam hợp, just as proud as Thái Tuế, and the only stance given Thiên Mã to build up the will to move forward. He writes that a person whose Mệnh falls in Tuế Phá, Tang Môn, or Điếu Khách is someone often dissatisfied with the work they do, who nevertheless holds out against the years through the willpower of Thiên Mã[2].
How Are Thái Tuế, Quan Phù, and Bạch Hổ Interpreted?
Among the three stars of the Thái Tuế tam hợp, Thái Tuế and Quan Phù are often mentioned as a pair governing litigation and disputes. Việt Viêm Tử records a verse saying that when a period meets Thái Tuế and Quan Phù, "quan phi khẩu thiệt quyết bất không" (lawsuits and quarrels will surely not be absent), and comments that quarrels and lawsuits are then hard to avoid, because he regards Quan Phù and Thái Tuế as "hưng tụng chi thần" (stars that stir litigation) and Cự Môn as "thị phi chi diệu" (the star of disputes); with Hóa Kỵ added, litigation comes all the more easily[3]. This is the wording of a verse about periods, not a conclusion for every chart that has these two stars.
Regarding Bạch Hổ, Việt Viêm Tử classifies this star as Kim, with its miếu position in Dậu. In his book, Bạch Hổ in a fallen position is linked to injury and accidents, while Bạch Hổ at its miếu position is described as firm, heroic, and courageous. He gives the pattern "Bạch hổ khiếu tây phương" and likens Bạch Hổ in Dậu to a tiger that has eaten its fill and lies resting in its den[3].
Thiên Lương has a separate section asking why the pair Bạch Hổ and Đường Phù becomes harmful. According to him, Bạch Hổ is a position in the Thái Tuế tam hợp, with a resolute drive to reach its goal; Bạch Hổ and Đường Phù meet only for the six birth-year stems Bính, Đinh, Mậu, Kỷ, Nhâm, and Quý, years in which he considers Lộc Tồn to stand against the yin-yang order, while the four stems Giáp, Ất, Canh, and Tân never have this pair[2].
Are Tang Môn, Điếu Khách, and the Tuế Phá Group Really Worrisome?
Tang Môn and Điếu Khách are two stars of the Tuế Phá group, often linked to mourning and harm. Việt Viêm Tử records the verse "Điếu-khách Tang-môn hựu tương ngộ, quản giao tai bệnh nhi tương công" (when Điếu Khách and Tang Môn meet again, calamity and illness press in together), and comments that by nature these two stars govern harm; if they do not meet Thất Sát, Thiên Hình, or Kình Dương it may still be avoided, but with Hóa Kỵ it is hard to avoid[3].
The books do not speak with one voice about this group. Việt Viêm Tử himself, in his star-by-star section, classifies Điếu Khách as Kim, governing "ngôn luận văn chương thi phú" (speech, letters, and verse), and writes that Điếu Khách joined by Thiên Mã and Thiên Khốc in Mệnh marks a gifted speaker[3]; Tử Vi đẩu số tân biên lists Điếu Khách as Hỏa[1]. Thiên Lương, as cited above, reads these three stars as a stance that calls for willpower rather than as an omen of mourning[2].
How Does the Thái Tuế Circle Interact with Other Star Rings?
Việt Viêm Tử groups the Thái Tuế circle with the Lộc Tồn circle and the Tràng Sinh circle as the stars used for reading each year's period, and reads the three rings as one set covering all five elements: Thái Tuế is Mộc, accompanied by Thiên Không and Quán Sách, which are Hỏa; Lộc Tồn is Thổ, accompanied by Kình Dương and Đà La, which are Kim; Tràng Sinh is Thủy. In his reading, the Thái Tuế circle corresponds to the person's luck and work, the Tràng Sinh circle to the ranks of family members, and the Lộc Tồn circle to the results of one's livelihood[3].
The continuation printed in Tử Vi nghiệm lý toàn thư uses the Thái Tuế circle as a measure of how favorable or difficult each period is, and divides it into four kinds of triangle: Thái Tuế, Tuế Phá, Thiếu Dương, and Thiếu Âm. According to this part, the Thiên Lương school treats a period reaching the Thái Tuế, Quan Phù, Bạch Hổ triangle as the most favorable time, and only the Thái Tuế and Tuế Phá triangles agree in yin-yang with the birth year[2].
Does the Thái Tuế Circle Decide One's Fate?
No. The three books cited here all place the Thái Tuế circle in relation to the whole chart rather than treating it as a deciding factor. Thiên Lương in Tử Vi nghiệm lý toàn thư stresses the role of Thân: in his view destiny sketches every scene in advance, good or bad, but whether it is carried out depends on one important factor, the acting Thân, and he asks: "Có phải đức năng thắng số là ở đây?" (Is this where virtue overcomes fate?)[2].
Tử Vi áo bí biện chứng học records the verse "Lộc đảo Mã đảo kỵ Thái-tuế chi hợp Kiếp Không. Vận suy, hạn suy hỷ Tử-vi chi giải hung ách" and explains: even if the two running periods meet the Lộc Mã pattern, meeting Thái Tuế together with Không Kiếp turns it into a broken pattern; a bad period needs the Tử Vi star to dissolve it[3]. So even within the verse, Thái Tuế is weighed together with other stars and does not stand alone as a conclusion.
Gợi ý của Nhật Nguyệt
When looking up the Thái Tuế circle on a chart, three steps are enough: find the palace bearing the birth year branch to locate Thái Tuế; count clockwise palace by palace to locate the other 11 stars; then see which of the four tam hợp groups the Mệnh and Thân palaces fall into. When reading an interpretation, note which book it follows, since the two books already differ on the element of Thái Tuế. This is a way of looking things up, not a prediction about anyone's finances, health, or fate.
