Zi Wei Dou Shu: chart structure and a learning path

What is Zi Wei Dou Shu?

Zi Wei Dou Shu is a traditional natal-chart system. Under a declared rule set it organises birth data into twelve palaces, major and auxiliary stars, si hua transformations, and luck periods. It is not a sun-sign horoscope, and it is not a single lucky-unlucky label for one star.

Calculation can confirm where a palace, star, or transformation lands under those rules. Symbolic meaning remains a conditional interpretation. Keep the actual placement, school differences, missing inputs, and real-world evidence in view.

• Check birth data, time zone, time precision, and the chart rules first.
• Read the topic palace together with its stars, trines, opposite palace, and si hua.
• Generate a chart when you need personal evidence; stay on wiki pages when you need the rule.

Learn the chart grammar first

A Zi Wei chart is a structure, not a list of independent star blurbs. Palace names move across fixed earthly-branch cells. Stars occupy those palaces. A theme is read with its trine and opposite palaces, not in isolation.

Learn structure, required inputs, the twelve palaces, and the fourteen major stars before adding si hua, auxiliaries, and luck periods.

Why FluxAstro publishes its chart rules

A chart in this wiki is a calculated object, not a personality label. FluxAstro uses the iztro engine. The minimum inputs are birth year, month, day, hour, and gender. You may enter a solar date or a declared lunar date. The hour is converted into a two-hour branch; 23:00 is treated as late Zi.

Schools may differ on year boundary, leap months, true solar time, transformation tables, and some star-placement verses. The same surface inputs can therefore yield different charts. FluxAstro records the engine version and the settings that change results so a chart can be recalculated and compared.

A beginner reading order

Name the question and the topic palace. Then read the stars in that palace, the full three-harmony and opposite structure, si hua, and only afterwards the luck periods.

A responsible reading says which chart facts it uses, which conditions weaken the claim, and what remains uncertain. It does not turn one symbol into a fixed character or a scheduled event.

Safety boundary

Traditional symbolism is a conditional reading frame. It is not medical, legal, or financial advice, and a single star or palace cannot replace the full chart, the declared settings, and the timing layer.
