ZiWei DouShu
ZiWei DouShu chart · twelve palaces and four transformations
ZiWei DouShu divides the chart into twelve palaces and places a set of stars into them from the birth data, reading where they land and how the four transformations fall. The chart is free and complete here, with the engine's raw output expandable; only the RM38 written reading is paid.
The eight methods
Tap a row to switch the method above — each tradition charts differently.
The chart is free. A written reading of this chart is RM38. see what is included
What each of the twelve palaces is read for
Life palace (overall structure and temperament), siblings, spouse, children, wealth (where money comes from and how it is used), health (where the body is weak), travel (going out and being away), friends (peers and subordinates), career (the shape of the work), property (home and savings), fortune (state of mind and enjoyment), parents.
A chart is not read palace by palace as a list of conclusions: each palace is pulled by three others (the 三方四正), so reading one in isolation usually misreads it. That is also why ZiWei depends on a complete chart more than BaZi does — omit one palace and one set of relationships disappears.
The four transformations: 禄 权 科 忌
The four transformations mark four stars governed by a given stem as 禄 (increase, flow), 权 (control, contest), 科 (reputation, order) and 忌 (obstruction, fixation). The stars in a palace do not change; the transformation applied to them does, and that changes the reading.
Most disagreement in ZiWei comes from the transformation table: different schools map stems to different stars, so identical birth data yields different transformations and therefore different conclusions. We state which table the chart uses rather than presenting a contested point as settled fact.
ZiWei and BaZi change year differently — and it matters
BaZi changes the year at 立春; ZiWei (and its flying-star and annual variants) changes it at Chinese New Year. A person born after 立春 but before New Year therefore falls in different years on the two charts.
Our casting handles this explicitly rather than applying one year rule to both systems. If you compare our result with another site, check which year rule they use first — the difference may be a convention, not an error.
Where free ends and paid begins
The twelve palaces and star placements are free, with the engine's raw output expandable and no account needed. The RM38 complete written reading covers each palace, the effect of where the transformations land, and the sequence of luck periods.
There is a separate flying-star reading (RM38): it reads how the transformations travel between palaces, including self-transformation and landing positions — a different method from palate-plus-stars. Buy them separately if you want both; we have not bundled them into a more expensive package.
Questions
method and scope
Is the ZiWei chart free?
Free, no account needed. The twelve palaces, star placements and transformation markers are all visible, and the engine's raw output can be expanded. The RM38 is for the complete written reading.
Is the flying-star reading the same as the ZiWei chart?
No. The ZiWei chart is read through the twelve palaces and where stars land; the flying-star reading follows how transformations travel between palaces, including self-transformation and landing. They are separate RM38 readings and can be bought independently.
Why can ZiWei and BaZi disagree by a year?
Because the year boundary differs: BaZi uses 立春, ZiWei uses Chinese New Year. Anyone born between those two dates falls a year apart. That is a difference of convention, not an error — and we apply each system's own rule.
