Qimen Dunjia Encyclopedia

What is Qimen Dunjia?

Together with Taiyi and Liuren, Qimen is one of the “Three Styles.” A chart is cast from a query time: convert the moment into the four pillars, then arrange heaven plate, earth plate, nine stars, eight gates, and eight deities into a nine-palace board used to judge success, timing, and strategy — historically called the “study of emperors.”

A Qimen chart centers on “stems stand for matters”: the day stem is the querent, the hour stem is the matter asked, and other stems have roles (Wu for resources, Geng for obstruction, Ding for information, etc.). Judgment finds the useful god’s palace, reads the heaven–earth stem pair (ten-stem response), then adjusts with gates, stars, and deities.

How we cast charts: rules fully open

DestinySeek uses the mainstream “Hour-family Qimen · rotating (palace) method · Chaibu bureau” standard. Every step below can be checked against classics and professional tools:

1. 1

   Four pillars

   Year pillar uses the exact Start of Spring boundary; month pillar uses solar-term boundaries; day pillar changes at 23:00 (late Zi belongs to the next day); hour pillar follows the Five-Rat sequence after the day change.

2. 2

   Bureau (Chaibu)

   Yang Dun from Winter Solstice to Grain in Ear; Yin Dun from Summer Solstice to Great Snow, by exact term boundaries. The triad follows the day pillar in the sixty Jiazi (Jia/Ji as fu-tou heads), then apply the bureau mnemonic to get the number.

3. 3

   Earth plate

   Sanqi–Liuyi order Wu Ji Geng Xin Ren Gui Ding Bing Yi; Yang Dun flies forward from the bureau palace, Yin Dun reverse.

4. 4

   Duty star & duty gate

   Find the decade head from the hour pillar; the star/gate on the earth-palace of that instrument are duty star/gate. If the decade head falls in Center-5, duty star is Tianqin and duty gate is Death Gate.

5. 5

   Heaven plate

   Duty star follows the hour stem: move it to the palace of the hour stem (Jia uses the decade-head instrument; Center-5 hosts at Kun-2). The other eight stars rotate in fixed ring order; Tianqin follows Tianrui and carries Center-5’s earth stem.

6. 6

   Eight gates

   Duty gate follows the hour branch: from the decade-head palace, walk the nine palaces (including center) by hour order within the decade (Yang forward / Yin reverse); align the eight gates on that ring.

7. 7

   Eight deities

   Zhi Fu, Teng She, Tai Yin, Liu He, Bai Hu, Xuan Wu, Jiu Di, Jiu Tian — start from the duty-star palace; Yang Dun clockwise, Yin Dun counter-clockwise.
