Reverse-Clash Lu Ma: Bing-Wu, Ding-Si and the Different Source Rules
The main Reverse-Clash Lu Ma passage discusses Bing-Wu and Ding-Si days, using strong summer Fire and repeated Wu-Horse or Si to invoke Officer (the role family that controls the birth-day element, often interpreted through rules and demands) in the opposite Water branch. Its direction reverses Flying Heavenly Lu Ma, without creating a missing Zi or Hai in the birth chart.
How do Bing-Wu and Ding-Si invoke Officer?
Gui is Officer for Bing and is hidden in Zi; Ren is Officer for Ding and is hidden in Hai. Bing-Wu therefore invokes Zi through Wu-Horse, and Ding-Si invokes Hai through Si. Ren and Gui do not have identical roles for both Fire stems.
| Main-source day | Repeated source | Implicit target | Officer | Target’s usual combination grouping |
|---|---|---|---|---|
| Bing-Wu | Wu-Horse | Zi | Gui | Chou Six Combination; Shen/Chen Water-trine members |
| Ding-Si | Si | Hai | Ren | Yin Six Combination; Mao/Wei Wood-trine members |
What is obstruction, and why is Chen not Si’s Six Combination?
Wu-Horse combines with Wei, and Si with Shen: ordinary ways the source branch may be bound. The passage additionally lists Chen as an obstruction for Ding-Si, although Chen–Si is not a standard Six Combination. It remains a passage-specific condition rather than a new combination rule.
An actual Gui or Zi for Bing, or Ren or Hai for Ding, must first be recognized as a real Officer or branch contact. Visible-Officer interpretation is different from an entirely implicit route.
Can the Hour Pillar participate? Why not use one isolated sentence?
The opening excludes the hour in its wording, but a later account in the same passage explicitly discusses a pattern appearing in Month and Hour rather than the Day Branch (the lower symbol in the birth-day column), and even gives Ding-Si day with Xin-Hai hour. The whole passage cannot be reduced to an absolute ban on the hour.
The compilation preserves different methods. This page uses the main Bing-Wu/Ding-Si summer-Fire account for the basic direction. A detailed decision about hour participation must identify which account is being used.
Why do some accounts list two days and others six?
The main account lists Bing-Wu and Ding-Si; a later version adds Bing-Yin, Bing-Xu, Ding-Wei and Ding-Mao. The closing authorial note favors two days based on the cited verses. The six-day account exists, but is not the same threshold as the main one.
The passage also allows a supported ordinary authority reading instead of rigidly applying the filled-target restriction. Compare the selected account and actual month when readings differ.
What is this useful for?
It helps explain why a Fire-heavy classical case may discuss Water authority, and why actual and implicit Zi–Wu contacts are different interpretive claims. It is not a method for correcting a birth time, adding elements or changing destiny.
Historical claims about office, rank or severe outcomes should not be applied directly to a person today. A clear reading first identifies the Day Master (the birth-day element used as the chart’s reference), real branches, absent target and source version.
