In Da Liu Ren (大六壬 dà liù rén), once the Heaven Plate is aligned, a second ring of symbols is placed on top of it: the twelve heavenly generals (十二天将 shí èr tiān jiàng). Each general is a category of affairs — authority, marriage, illness, theft, documents — and where each one lands tells the reader which department of life a branch is speaking for. If the plates give the board its skeleton, the generals give it a vocabulary.
This piece explains what the twelve heavenly generals mean and, in principle, how their order is set: why the sequence runs forward or backward depending on whether the Noble is a day Noble or a night Noble. We describe the logic, not a specific cast — the placement itself is fixed work for a plate engine, not something to improvise.
What the generals ride on
The generals do not sit on the fixed Earth Plate. They ride the Heaven Plate (天盘 tiān pán) — the rotating ring set by placing the Monthly General (月将 yuè jiàng) over the hour branch. Because that ring has already turned to answer the moment, the generals turn with it, and each one comes to rest over a particular Earthly Branch. For the mechanics of that alignment, see the Heaven and Earth Plates of Da Liu Ren; for where the whole system sits, the Great Six Ren explained.
Anchoring the ring of generals is the Noble, 贵人 (guì rén) — the “honoured person.” The Noble marks the starting palace, and every other general is counted out from it. Get the Noble’s seat and the direction of counting right, and the other eleven fall into place.

>The twelve heavenly generals and their categories
Each general stands for a class of matter. The following categories are copied from our Da Liu Ren reference; read them as the affairs a general governs when it appears on a lesson or transmission.
General
Pinyin
Category / meaning
贵人 Noble
guì rén
Help, officials, authority
螣蛇 Snake
téng shé
Alarm, fright, illusion
朱雀 Vermilion Bird

News, documents, disputes, fire
六合 Liu He
liù hé

勾陈 Gou Chen
gōu chén
Entanglement, land, delays, lawsuits
青龙 Green Dragon
qīng lóng
Wealth, joy, promotion
天空 Sky Void
tiān kōng
Emptiness, deceit, hollow words
白虎 White Tiger

太常 Tai Chang

玄武 Xuan Wu
xuán wǔ
Theft, loss, deception, hidden
太阴 Tai Yin
tài yīn
Concealment, women, privacy
天后 Tian Hou
tiān hòu
Women, marriage, nurture
You will notice categories overlap on purpose. Marriage draws on Liu He, Tian Hou, and Tai Yin; documents on Vermilion Bird and Tai Chang; danger on White Tiger and the Snake. That redundancy is a feature — when a reader picks the category symbol for a question, having several candidate generals lets the board itself show which one is active.
Day Noble and night Noble: 昼贵 and 夜贵
The Noble does not sit in the same place around the clock. Which branch the Noble occupies depends on two things: the day’s stem (日干 rì gān) and whether the divination hour is daytime or night. This gives two versions of the Noble — the day Noble, 昼贵 (zhòu guì), used for daytime hours, and the night Noble, 夜贵 (yè guì), used for night hours.
The day stem selects a pair of Noble branches; the day-or-night split then chooses which of the pair is in force. The exact stem-to-branch table is classical and fixed, and it is one of the items our reference flags to verify against a current source before any engine ships it — so we describe the rule rather than assert a specific placement here. Traditions also differ on the precise boundary between “day” and “night” hours, much as Ba Zi schools differ on the late Zi hour; a careful practitioner states the convention being used.
Forward or backward: 顺 and 逆 ordering
Once the Noble’s seat is known, the other eleven generals are counted out from it in a fixed sequence. The direction of that count is what the day/night Noble decides. When the day Noble is in force, the generals run forward, 顺 (shùn), in one rotational direction around the plate; when the night Noble is in force, they run backward, 逆 (nì), the other way. The Noble is the hinge, and the day-or-night state flips the whole ring’s sense.
This is why the same twelve heavenly generals can produce very different boards on two days: a shift in the Noble’s palace or in the direction of counting moves every general to a new branch, and therefore to a new relationship with the day. Those relationships — whether a general’s branch generates or controls the day — are read through the Four Lessons of Da Liu Ren (四课 sì kè), where each lesson carries its riding general.
Why the generals matter to a reading
On their own, the branches of a board are neutral. The generals are what let a reader say a matter concerns officials rather than money, or concealment rather than open dispute. A White Tiger on an active branch turns attention to illness or the road; a Green Dragon there speaks of wealth or advancement. The art is in matching the question to the right general, then reading whether that general’s position is strong or weakened for the season — the same relational thinking that underlies a Ba Zi (八字 bā zì) chart.
Da Liu Ren answers a question; Ba Zi maps a life. If you are new to reading elements and their generate-and-control relationships, the clearest place to start is your own chart — plot it free with the Ba Zi calculator, then explore what Ba Zi is before returning to the boards of the Great Six Ren.
