The Twelve Growth Stages in Chinese Astrology

The term 长生十二神, also called 十二长生 or 生旺死绝, refers to one and the same set of twelve stages used to describe the condition of a heavenly stem in a given earthly branch. Different names are used in different traditions or contexts, but they point to the same framework. This entry outlines how the twelve stages are ordered, how the sequence runs differently for yang and yin stems, where a major divergence appears in the treatment of fire and earth, and what exactly the system measures.

十二神与十二长生是同一套

长生十二神，十二长生, and 生旺死绝 are not separate systems. They are alternative names for a single twelve-stage cycle. The word 长 in 长生 means growth or birth, and the set as a whole describes a life-like progression from emergence through maturity, decline, rest, and preparation for the next cycle. In bazi analysis, this cycle is applied to each of the ten heavenly stems across the twelve earthly branches. A practitioner may say a stem is at 长生 in a certain branch, or may say that branch is the 长生之地 of the stem; both statements use the same underlying table. The name 十二神 can suggest personified stages, but the stages remain the same twelve positions.

十二个阶段的次序

The twelve stages in order are:

长生，沐浴，冠带，临官，帝旺，衰，病，死，墓，绝，胎，养.

长生 is the first stage, indicating birth or initial emergence. 沐浴 follows, often associated with washing after birth and with a state of vulnerability or exposure. 冠带 indicates the stage of wearing the cap, a marker of early social maturity. 临官 is the stage at which the stem reaches an official-like standing; this is the position called 禄, where the heavenly stem is most established and capable in its earthly branch. 帝旺 is the point of maximum strength, the extreme of flourishing. For a yang stem, the 帝旺 position is also called 羊刃. After 帝旺 come the descending stages: 衰，病，死，墓，绝，胎, and 养. 墓 is the grave or storage position, also called 墓库. 绝 is the most depleted position, where the stem is at its weakest. 胎 and 养 then mark hidden preparation and nourishment before the next 长生. The sequence is fixed; what changes between stems is where in the twelve branches the sequence begins and in which direction it proceeds.

阳干顺行，阴干逆行

The twelve-stage cycle is applied in opposite directions to yang and yin stems. Yang stems move forward through the earthly branches in the ordinary order; yin stems move backward. For example, 甲木, the yang wood stem, has its 长生 at 亥 and its 帝旺 at 卯. From 亥, the sequence moves forward: 亥 is 长生，子 is 沐浴，丑 is 冠带，寅 is 临官, and 卯 is 帝旺. By contrast, 乙木, the yin wood stem, has its 长生 at 午 and its 帝旺 at 寅. From 午, the sequence moves backward: 午 is 长生，巳 is 沐浴，辰 is 冠带，卯 is 临官, and 寅 is 帝旺. The same principle applies to the other stem pairs. This directional rule means that the 长生 position of a yin stem is not simply the next stage after the yang stem’s 长生; it occupies a different branch and produces a different distribution across the twelve positions.

火土同长生这一处分歧

The treatment of the fire and earth stems is the most common point of divergence in twelve-stage tables. This site uses the system in which fire and earth share the same 长生 positions. Under that system, 丙 and 戊 both have 长生 at 寅, and 丁 and 己 both have 长生 at 酉. The same pairing is then carried through the remaining stages: because 丙 and 戊 begin at 寅 and move forward, their 帝旺 is at 午; because 丁 and 己 begin at 酉 and move backward, their 帝旺 is at 巳. Other lineages use a different arrangement for the earth stems, most often assigning 戊 and 己 separate starting points from the fire stems. Some assign 戊 长生 at 寅 and 己 长生 at 酉, as here; others assign 戊 长生 at 申 and 己 长生 at 卯, or use another variant. Because this affects the entire table for the earth stems, a chart read under one convention may differ in the twelve-stage labels for 戊 and 己 from the same chart read under another convention. The divergence is not minor; it changes which branch is treated as 禄，羊刃，墓, or 绝 for those stems. When comparing texts or software, the first point to check is which 火土 convention is being used.

它衡量的是哪一件事

The twelve-stage system measures the state of a single heavenly stem in a single earthly branch. It is not a summary of the whole chart, and it is not a ranking of overall quality. The full table contains one hundred and twenty cells: ten heavenly stems each placed in twelve earthly branches. Each cell records one of the twelve stages. A stem may be at 长生 in one branch, at 墓 in another, and at 绝 in a third; each of those entries is a local condition, not a verdict on the chart as a whole. The meaning of a stage is always read in relation to the specific stem and branch involved.

帝旺 is the point of greatest strength, but it is not automatically the best stage. For a yang stem, the 帝旺 position is also 羊刃, the blade position. A stem at its extreme can be over-strong, and that condition carries its own interpretive rules rather than being treated as a simple optimum. Likewise, 临官 is the 禄 position, indicating that the stem is well placed and capable, but this too is a specific state rather than a universal good. The twelve-stage label tells the reader how the stem’s energy stands in that branch: whether it is emerging, strengthening, peaking, weakening, resting, or being stored. It does not by itself determine the outcome of a chart.

Because the system operates stem by stem and branch by branch, the same branch can be 长生 for one stem and 死 or 绝 for another. For example, 亥 is 长生 for 甲木, but it is not the same stage for the other nine stems. The table must therefore be read as a grid of individual conditions. When a text says a stem is at 临官 or 帝旺 in a branch, it is making a limited claim about that stem’s condition in that location. The surrounding stems, the interactions among them, and the structure of the chart remain separate considerations.
