Gui 癸 — the Yin Water Day Master
Gui is rain, dew, the deep well: water that arrives quietly and reaches places a river never will. If your day stem is 癸, the tradition reads intuition and penetration — understanding a situation before being able to explain how.
癸水至弱，達於天津。Gui water is the weakest, yet it reaches the heavenly ford. — Di Tian Sui (滴天髓), the classical verse for Gui
The image
The image behind Gui is rain, dew and the deep well, and it is not decoration — it is the working model. When a practitioner says a Gui chart is strong or weak, the question underneath is always the same: does this image have what it needs to do what it is for, in the season it was born into?
How the tradition reads Gui
Gui is rain, dew, the deep well: water that arrives quietly and reaches places a river never will. The tradition reads Gui as intuitive, private and quietly penetrating — the Day Master most likely to understand a situation without being able to explain how. Gui charts tend to work below the surface: they accumulate, notice, and then arrive at a conclusion fully formed. Their strength is depth and an unusual capacity for empathy that does not need to be displayed. The shadow is seepage. Water that has no container spreads thin, and Gui-born people can absorb other people's weather until their own is unrecognisable, or keep a real worry entirely private until it has grown. The classical remedy is a vessel: a few trusted people who are told the truth early, and routines that give the inward current somewhere to go.
Supported, and under pressure
When the chart supports it
- Depth of perception and an empathy that does not need to be displayed.
- The capacity to arrive at a conclusion fully formed, having done the work below the surface.
When it is under pressure
- Absorbing other people's weather until an own mood is unrecognisable.
- Keeping a real worry entirely private until it has grown much larger than the event.
Gui in the four pillars
A day master is one stem, but it lands in four different positions, and the classics read each position as a different arena. These are the standard readings for a Gui stem:
- Year — an early environment that rewarded noticing, often quiet or private in some way.
- Month — a career in insight work: research, therapy, writing, analysis, anything where the invisible part is the job.
- Day — the self as the well; the branch underneath is the aquifer, and Gui charts are read by how deep the supply actually goes.
- Hour — later depth: a body of work that accumulates rather than announces itself.
Gui and the other elements
Gui is produced by Metal and produces Wood; it quenches Fire and is contained by Earth. Metal keeps it clear — the classical image is fine metal producing clean water — and Earth gives it a vessel. A Gui chart with neither is read as water spreading thin: perceptive, ungrounded, and hard to hold a decision with.
Fire is the thing Gui most reliably affects and least wants too much of: a small flame is warmth and company, too much is evaporation. The tradition reads 丁 and 癸 together with particular care, since the two are the smallest expressions of their elements and their balance is unusually visible in ordinary life.
Ten seconds, no signup: the calculator returns your day master, the weighted balance of all five elements, and which of them your month is feeding.

Questions people actually ask
Are Gui Day Masters overly sensitive?
Perceptive first, sensitive as a consequence. Gui is read as the water that reaches places a river will not — the undercurrent, the thing not said. In charts with good Metal and Earth that becomes insight with a container; without them it becomes absorption, which is much harder to work with.
What is the 'vessel' the tradition recommends for Gui?
A few trusted people who are told the truth early, and routines that give the inward current somewhere to go. Gui charts are not short of understanding; they are short of outlets. The practical instruction is almost always the same: say the thing out loud before it has finished growing.
