Fourpillars

Four Pillars, Zi Wei Dou Shu, and Western astrology all take a birth moment and build a structure from it. That shared premise makes them look like variations on one idea. They are not. Two of them share a civilisation and almost nothing else mechanically. The third developed on the other side of Asia from unrelated sources. This article sets them side by side — where they came from, how they are built, how they handle time, and where each one's reasoning becomes contested.

The twelve palaces are what make Zi Wei Dou Shu structurally different from Four Pillars. Where BaZi derives life domains indirectly, from relationships between elements, Zi Wei assigns each domain its own compartment and puts stars in it. That design has a practical consequence. A question about marriage goes to a specific place on the chart. There is no equivalent move in Four Pillars, where the same question requires reading the whole configuration. This article covers all twelve palaces, how they relate to each other, and why no palace is ever read alone. For chart structure generally, see our introduction to Zi Wei Dou Shu . How the Palaces Are Ordered The sequence is fixed. Once the Life palace is located — determined by the lunar birth month and hour — the remaining eleven follow in a set order around the chart. The order is not arbitrary. It moves outward from the self through immediate family, then to material and social concerns, then to the conditions one was born ...

Two people can be born with nearly identical star arrangements and receive completely different readings. The variable that separates them is the four transformations — the layer that sits on top of the star placements and overrides their default meanings. For one of the two main lineages, the transformations are not merely a layer. They are the primary object of analysis, and star meanings are secondary to where the transformations land and how they chain between palaces. This article covers what they are, how they are assigned, and how practitioners trace them. For chart structure and the stars themselves, see our guide to the fourteen major stars . What a Transformation Does Four specific stars in any chart receive a modifier. The modifier does not replace the star's character — it redirects it, determining whether the star's energy flows outward, asserts itself, seeks recognition, or binds. Which four stars receive them is determined entirely by the Heavenly Stem ...

A Zi Wei Dou Shu chart contains dozens of stars, but fourteen of them carry the analytical weight. These are the major stars, and where they land across the twelve palaces determines most of what a reading says. The system's organising metaphor is an imperial court. Each major star holds an office — sovereign, general, treasurer, strategist, diplomat — and reading a chart means asking which officials have been posted to which departments of a life. This guide covers all fourteen. For chart structure and the twelve palaces, start with our introduction to Zi Wei Dou Shu . Two Groups, One Sequence The fourteen divide into two series. The Zi Wei series of six follows the position of Zi Wei itself; the Tian Fu series of eight follows Tian Fu. Once either anchor is located by formula, the rest of its series falls into place automatically. This matters practically. The stars are not distributed independently — fixing one position fixes many others. Certain combinations recur c...

Zi Wei Dou Shu is the East Asian chart system most Western readers have never heard of. In Taiwan and Hong Kong it rivals Four Pillars in popularity; in English it remains thinly documented, and much of what circulates online is a compressed translation of a single lineage's material. This article covers where the system came from, how a chart is constructed, and how practitioners read one. As with everything on this site, the aim is to explain the reasoning — not to produce readings. What the Name Means 紫微斗數 breaks into three parts. Zi Wei — "Purple Subtlety" — is the chief star of the system, named after the Purple Forbidden Enclosure, the circumpolar region of the Chinese sky that contains the pole star. In imperial cosmology this region was the celestial court, with the emperor's star at its centre. Dou refers to the Dipper. Shu means calculation or method. Roughly: the method of calculating by the Purple Subtlety and Dipper stars. One point deserves ...
