What do Zi Wei's supporting, malefic and minor stars actually do?
Content version · · Sources & references
Start with what a malefic label can establish, then trace placements to their inputs and read classical combinations in their stated conditions.

Trace each placement to its inputs, then read its palace and combinations. Keep natal and timing layers distinct.

The word “malefic” is not a verdict
Seeing a star translated as malefic can make a chart look alarming before any placement has been checked. In this article it is a traditional grouping label. It does not establish that harm will occur, and counting those labels is not a measure of a person's risk. The useful first question is which rule placed that star and what other chart conditions are actually present.
A Zi Wei chart can show many more names than the fourteen major stars. The number displayed depends on the chosen collection. Supporting and minor stars need their own placement record; a long list does not automatically provide more individual evidence.
Audit three different dependencies
Zuo Fu and You Bi depend on the birth month in the quoted text. Wen Chang and Wen Qu depend on the double-hour. San Tai and Ba Zuo require the birth month and day: the month first places Zuo Fu and You Bi, then the birth day is counted from those positions. Calling the last pair “day-based” without its starting positions would hide an input.
Lu Cun offers a contrasting example. Its branch depends on the year stem; Qing Yang and Tuo Luo are then placed around Lu Cun. In a Yin Water year, the quoted example puts Lu Cun at Rat, Qing Yang at Ox and Tuo Luo at Pig. People with that year stem share these branch placements under the rule. They do not therefore share a Life Palace, a complete chart or an established life outcome.
A placement reference, with its edition stated
| Group | Stars | Placed by | Rule in volume two |
|---|---|---|---|
| Six auspicious | Zuo Fu, You Bi | birth month | Zuo Fu counts forward from Dragon and You Bi backward from Dog, the first month at the start |
| Six auspicious | Wen Chang, Wen Qu | birth hour | Wen Chang counts backward from Dog and Wen Qu forward from Dragon, the Rat hour at the start |
| Six auspicious | Tian Kui, Tian Yue | year stem | a rhyme gives two branches per stem, e.g. Yang Wood, Yang Earth and Yang Metal years at Ox and Goat |
| Lu Cun | Lu Cun | year stem | Yang Wood at Tiger, Yin Wood at Rabbit, Yang Fire and Yang Earth at Snake, Yin Fire and Yin Earth at Horse, Yang Metal at Monkey, Yin Metal at Rooster, Yang Water at Pig, Yin Water at Rat |
| Six malefic | Qing Yang, Tuo Luo | follow Lu Cun (year stem) | one branch ahead of Lu Cun and one behind: in a Yin Water year Lu Cun is at Rat, Qing Yang at Ox, Tuo Luo at Pig |
| Six malefic | Huo Xing, Ling Xing | year branch sets the start | Tiger, Horse and Dog years start Huo Xing at Ox and Ling Xing at Rabbit; Monkey, Rat and Dragon years start them at Tiger and Dog, and so on |
| Six malefic | Di Kong, Di Jie | birth hour | with Pig as the Rat hour, Di Jie counts forward and Di Kong backward |
| Tian Ma | Tian Ma | year branch | Tiger, Horse and Dog years at Monkey; Monkey, Rat and Dragon at Tiger; Snake, Rooster and Ox at Pig; Pig, Rabbit and Goat at Snake |
| Minor | Tian Xing, Tian Yao | birth month | the first month at Rooster and at Ox respectively, counting forward |
| Minor | Hong Luan, Tian Xi | year branch | count backward from Rabbit to the year branch for Hong Luan; Tian Xi sits opposite |
| Minor | San Tai, Ba Zuo | birth month sets Zuo Fu and You Bi; birth day determines the count | day one at Zuo Fu's palace counting forward gives San Tai; day one at You Bi's palace counting backward gives Ba Zuo |
For Huo Xing and Ling Xing the cited passage gives year-group starting positions. A method that also counts to the birth hour needs that additional rule documented; the starting palace must not be mistaken for the final position. The text calls the hour-based reverse-counted star Tian Kong, whereas the modern label used here is Di Kong. Keep it separate from a different year-based star also named Tian Kong.

“Principal” in an old text is not “major” in every app
Volume two's northern/southern classification includes Wen Chang, Wen Qu, Zuo Fu and You Bi among eighteen principal stars. This article uses the familiar modern grouping of fourteen major stars, six auspicious stars, six malefic stars, Lu Cun/Tian Ma and other minor stars. These are editorial categories for reading this article, not a claim that every school divides the list identically.
The Four Transformations are another distinction: they describe transformations attached to particular stars under a selected rule. They should not be counted as four extra physical bodies. When two sources disagree about which names belong in a group, check the definitions before treating the charts as contradictory.
Use the conditions in a passage, not just its favourable word
Volume one's star discussions include combinations with other stars and with palace conditions. Those passages support reading the conditions together; they do not prove that every classical sentence follows one universal modern reading order. Here the palace identifies the topic, and the actual combination supplies the material for interpretation. A claim about the topic still needs to remain separate from a verified fact about someone's life.
A statement based solely on a shared year-star label is weak personal evidence. To make a chart-specific comparison, retain its branch, the palace topic assigned in this chart, companions, layer and chosen brightness convention. A year-star placement can be shared while those other features differ.
Keep absent and unknown distinct
A palace with no major star is not automatically empty of all content. Check which supporting stars are really there and which transformation relationships the selected method uses; do not invent them merely because an article says empty palaces still matter. Empty palaces and borrowed stars deals with that distinction.
Finally, natal placements and stars introduced by a decade or year belong in separate records. Hong Luan alone is not a wedding date, Tian Xing alone is not a lawsuit, and an unfamiliar star name is not proof of an additional danger. Where a source or a program's rule is missing, record the uncertainty instead of supplying a conventional-sounding conclusion.
