TL;DR: In Bát Tự, lưu niên is the stem and branch of the year under consideration, while the Grand Duke is the name for the presiding lord of that year, which the book Tam mệnh thông hội calls "niên trung thiên tử", the king of the year. Tuế vận tịnh lâm is when the stem and branch of the decade pillar duplicate the flowing year; Tam mệnh thông hội records that it is inauspicious only when that stem and branch is Yang Blade or Seven Killings, while as wealth, officer or seal it is also auspicious. A correct reading must place the flowing year against the whole four pillars, examining which stem and branch of the destiny and decade pillar the flowing year's stem and branch act upon, rather than looking only at a single Grand Duke star.
How Do Annual Pillar and Tai Sui Differ?
Annual pillar (luu nien) is the stem and branch of the year under review, for example a Yi Si, Jia Chen, or Bing Wu year. Tai Sui, in its common BaZi usage, is precisely that annual stem and branch, but personified as the year's ruling power. Tam Menh Thong Hoi by Wan Minying of the Ming dynasty defines it directly: "The Tai Sui is the emperor within the year, the honored elder of all spirit-killers in a year," meaning Tai Sui is king of the year, the senior of all shen sha for that year[2].
Three things often lumped together must be distinguished. First is the calendrical stem and branch of the year, the annual pillar, which is a calculable fact cross-checkable against a printed calendar. Second is the position of Tai Sui on the chart, the branch of the birth year or of the year under review depending on the system, which is a convention for placing stars. Third is the folk notion of the "year of one's age," holding that one who offends Tai Sui meets trouble all year, which is oral belief, not a rule of Zi Ping.
In Zi Ping, the central concept is not "offending Tai Sui" but the relation between the annual pillar, the four pillars, and the decade pillar. Tam Menh Thong Hoi continues: "Decade and annual pillar are two, mutually outer and inner, and on them human fate's fortune and misfortune, life and death depend," meaning decade and annual pillar are outer and inner to each other and jointly decide fortune[2]. This is the fundamental difference from folk phrasing.
What Is Sui Yun Jing Lin?
Sui yun jing lin is the case where the annual pillar's stem and branch completely match those of the currently active decade pillar. For example, a chart running a Geng Chen decade meets a Geng Chen year: this is called tuế vận tịnh lâm (歲運并臨).
Tam Mệnh Thông Hội, in its section Luận Thái Tuế, defines it directly: "如甲子流年又是甲子運，謂之歲運并臨，獨羊刃七煞為凶，財官印綬亦吉", meaning that when a Giáp Tý year meets a Giáp Tý decade it is called tuế vận tịnh lâm, that it is unfavourable only when that stem and branch are Dương Nhận or Thất Sát, and that it is also favourable when they are tài, quan or ấn thụ; the classic line "歲運并臨，災殃立至", the book says, refers to Dương Nhận alone[2]. Phục ngâm and phản ngâm are different names, which the book uses for the relation between the year or decade and the day pillar: if the year or decade clashes with the birth month, disaster surely follows; if it stands opposite the day pillar, it is called phản ngâm; if it presses upon the day pillar, it is called phục ngâm; both are unfavourable to the six relations and prone to unexpected loss of wealth[2].
Mechanically, when decade and annual pillar coincide, one element of the chart is doubled at once, and every relation of punishment, clash, harm, or destruction that stem and branch cause to the four pillars occurs twice. Classical texts do not call this fixedly auspicious or inauspicious but judge by favorable and unfavorable elements. If that element is a favorable useful god, it gets a chance to manifest; if it is an unfavorable god, pressure also doubles.
Trich Thien Tuy, expounded by Ren Tieqiao of the Qing dynasty, stresses the underlying principle: "The Way of Earth" says that whether the five qi are partial or complete determines fortune; "The Way of Man" says compliance is auspicious, opposition inauspicious[1]. Applied to sui yun, this means one must examine whether the annual qi accords with the season and the chart's favorable and unfavorable elements, not merely count repetitions.
In What Order Should the Annual Pillar Be Read?
The reading order has four steps, moving from the stable to the changing.
- Step one, determine the chart's favorable and unfavorable elements: whether the day master is strong or weak, which element the chart needs, which it fears. This is the foundation; without it, any conclusion about the annual pillar is meaningless.
- Step two, see whether the annual stem and branch are favorable or unfavorable to the chart. Tam Menh Thong Hoi says: if running a good decade while the day stem controls the annual heavenly origin, the harm is light; if running a bad decade while the day stem controls the year stem, the harm is heavy[2].
- Step three, see how the annual pillar acts on which branch of the four pillars: whether there is combination, clash, or punishment. Combining with the day or month branch is a close relation; clashing with the day branch is direct change to oneself.
- Step four, see the annual pillar against the decade pillar: same element, mutual generation, mutual control, or complete match. This step decides the magnitude of the event.
One point classical texts note: Tam Menh Thong Hoi distinguishes heavy from light when the day stem controls the year stem by yin and yang. The text says "generally when the day offends the year lord, with the five yang stems it is heavy, with the five yin stems it is light," meaning a yang stem is heavy, a yin stem light. The text also says that if the day stem is Thiên Đức or Nguyệt Đức and Thái Tuế is the useful god, there is no fault and there is even gain[2].
What cases are included in the table comparing cases where the Annual Pillar meets the Decade Pillar?
| Case | Stem-branch relation | What Tam Mệnh Thông Hội records | Note |
|---|---|---|---|
| Tuế vận tịnh lâm | Decade stem-branch matches annual stem-branch | Unfavourable only for Dương Nhận and Thất Sát; also favourable for tài, quan, ấn thụ | Check what that stem-branch is for the chart |
| Phục ngâm | Year or decade presses on the day pillar | Unfavourable to the six relations, unexpected loss of wealth | Not the same as tuế vận tịnh lâm |
| Phản ngâm | Year or decade stands opposite the day pillar | Unfavourable to the six relations, unexpected loss of wealth | Same group as phục ngâm |
| Year or decade clashes the birth month | Year or decade clashes the birth-month branch | Disaster surely | The book treats the birth month as the origin of the luck cycle |
| Day stem controls year stem | Day stem controls the annual heavenly origin | Good decade, light harm; bad decade, heavy harm; heavy for yang stems, light for yin stems | The book calls it the day offending the year lord |
| Year stem controls day stem | Annual heavenly origin controls the day stem | There is harm but it is light, since the higher governing the lower is in order | The book calls it the year injuring the day stem |
This table summarizes cases Tam Mệnh Thông Hội discusses in the two sections Luận Thái Tuế and Tổng luận tuế vận[2]. The table is only a reading frame, not a substitute for examining the whole chart.
How are combination and clash between the Annual Pillar and the Four Pillars understood?
Tam Menh Thong Hoi devotes a separate section to "hui qi," the case where the annual stem combines with the day or hour stem. The text says: "The day stem and hour stem should not combine with the heavenly origin of Thái Tuế; if they combine, it is called hối khí," meaning the day and hour stems should not combine with the year stem; such combination is called hối khí[2].
The text distinguishes two directions of combination. When the day stem combines with the year stem, for example a Jia day meeting a Ji year, it is called the day stem combining Tai Sui, which the text calls heavy disaster. When the year stem combines with the day stem, for example a Ji day meeting a Jia year, it is called Tai Sui combining the day stem, which the text calls lighter disaster. The text adds: if the year position is near the day pillar, specifically five branches before the day branch (日前五辰), and meets combination, it is called "Thái Tuế enters the house, hối khí arrives at the gate," portending calamity[2].
It must be said clearly: this is the convention of Tam Menh Thong Hoi, not a universal rule all schools follow. Modern Zi Ping schools tend to stress favorable and unfavorable elements and rooting rather than the names hui qi and ru zhai. Readers should know both approaches and know that this article presents according to Tam Menh Thong Hoi's convention.
On clash, Tam Mệnh Thông Hội groups phục ngâm and phản ngâm as unfavourable. In the section Luận Thái Tuế the book gives one exception, for the case where stems control and branches clash: "若天衝地擊，柱中原有，流年再遇，亦無大咎", meaning that when the clash of heaven and strike of earth is already present in the pillars, meeting it again in the annual pillar is no great fault[2]. This differs from the mechanical reading that any clash is disaster.
What Is the Folk Notion of the "Year of One's Age"?
In folk belief, a year whose branch is the same as the branch of one's birth year is called năm tuổi (the year of one's age), and many people believe such a year is prone to misfortune. This phrasing is common in daily life but is not a rule of Tử Bình.
A distinction is needed: the folk notion of "offending Tai Sui" usually calculates the birth-year branch against the year branch under review, while Zi Ping examines the relation between the annual stem and branch, the whole four pillars, and the chart's favorable and unfavorable elements. The two give different results. A person may "offend Tai Sui" by folk reckoning while the chart actually meets the annual pillar's favorable useful god, and vice versa.
Some lookup sites today present further concepts such as Tai Sui of the current year, clashing Tai Sui, punishing Tai Sui, harming Tai Sui, and destroying Tai Sui. This five-fold classification by birth-year branch is widespread in recent applied materials and is not found in Tam Mệnh Thông Hội or Trích Thiên Tủy. Tam Mệnh Thông Hội has only the name chinh Thái Tuế (征太歲), used when the stem and branch of the day or of the decade clash with and control those of Thái Tuế, or the reverse[2]. Readers should treat it as an extended interpretation, not original doctrine.
What is Trich Thien Tuy and the "Qi" Principle of the Annual Pillar?
Trich Thien Tuy, expounded, opens with three foundational chapters: The Way of Heaven, The Way of Earth, The Way of Man. The Way of Heaven says "to know the one source of the three origins and ten thousand methods, first observe what the sovereign carries and the work of the spirit," meaning to understand all methods one must first see what the sovereign carries and the spirit's function[1]. The Way of Earth says "the five qi complete or not determines fortune," meaning whether the five qi are complete determines fortune[1]. The Way of Man says "one who bears heaven and treads earth is noble; compliance is auspicious, opposition inauspicious," meaning humans who bear heaven and tread earth are noble; compliance is auspicious, opposition inauspicious[1].
Applied to the annual pillar: the qi of the year under review must be placed in relation to the qi of the four pillars. If the annual pillar brings an element the chart lacks and needs, that is compliant qi. If it brings an element the chart has in excess, that is opposing qi. The Tuế vận section of Trích Thiên Tủy reads: "休囚係乎運，尤係乎歲，戰沖視孰降，和好視孰切", meaning that weakness and confinement depend on the decade and still more on the year; in conflict and clash, see which side yields, and in harmony, see which side is closer. Nhậm Thiết Tiều comments that Thái Tuế governs the rise and fall of one year, like a person one meets, so the heavenly stem carries the weight although the branch cannot be ignored; when the day offends the year lord, a day master that is vượng tướng suffers no fault, while one that is hưu tù meets misfortune[1].
Ren Tieqiao in his commentary also stresses that stems are heavenly origin, branches earthly origin, and hidden stems in branches human origin, and human fate does not escape the principle of these three origins[1]. So with the annual pillar: the year stem acts on the pillars' heavenly origin, the year branch on earthly and human origins. Reading the annual pillar is reading three layers of interaction, not just one character.
What are common errors when reading the Annual Pillar?
- First error, treating Tai Sui as an independent star with fixed auspicious or inauspicious nature. In Zi Ping, Tai Sui is only the year's stem and branch; its fortune arises from interaction with the chart.
- Second error, examining only the branch and ignoring the stem. Tam Menh Thong Hoi states clearly "the year uses heavenly origin, the decade uses earthly branch," meaning the annual pillar emphasizes the stem, the decade pillar the branch[2].
- Third error, seeing sui yun jing lin and concluding great misfortune at once. Tam Mệnh Thông Hội says it is unfavourable only when the matching stem and branch are Dương Nhận or Thất Sát, and also favourable when they are tài, quan or ấn thụ[2].
- Fourth error, ignoring the decade pillar. Tam Menh Thong Hoi says sui and yun are outer and inner; the annual pillar alone is not enough to discuss fortune.
- Fifth error, reading the annual pillar without knowing the chart's favorable and unfavorable elements. This is the gravest error, since every name such as fu yin, fan yin, hui qi only has meaning when one knows what the chart needs and fears.
What are Nhat Nguyet's suggestions for reading your own Annual Pillar?
Nhat Nguyet's suggestion: when reading a year for yourself, do four things in order. One, write out the stem and branch of the annual pillar and the active decade pillar. Two, write clearly which element is the favorable useful god and which the unfavorable god for your chart according to the approach you use. Three, mark which pillars in the four pillars have combination, clash, or punishment with the annual stem and branch. Four, compare with events that occurred in years of similar structure to check your own reading.
Do not treat a year as a "calamity year" merely because it matches the birth-year branch, nor as "greatly auspicious" merely because the annual pillar is a favorable god. Zi Ping reads interactions, not labels. Conclusions about finances, health, and marriage should be taken as prompts for observation, not certain predictions.
