What Is Stem-Branch Dual Link (干支雙連) in BaZi?
Learn how two complete pillars link by consecutive stems and branches, the source examples, Two Principles Noble Pair alias, qi direction and product limits.
Overview
Stem-Branch Dual Link is the workbook’s English name for 干支雙連. The source illustrates two complete pillars whose Heavenly Stems and Earthly Branches both move by one position: Jia-Wu with Yi-Wei, Bing-Shen with Ding-You, Wu-Xu with Ji-Hai, and Jia-Zi with Yi-Chou. It also gives Geng-Wu with Xin-Wei and associates Jia or Geng with the noble branches Chou and Wei, and Yi or Xin with Zi and Wu. The aliases “Two Principles Noble Pair” and “Linked-Pearl Fortune Spirit” belong to that source rhetoric. A final note distinguishes advancing and receding qi by the order of Bing-Yin and Ding-Mao, but the compact wording does not define a complete directional algorithm. OpenFate does not detect this pattern or let adjacency suppress other interactions.

Both halves of the same two pillars must link
The rule compares two actual sexagenary pillars. Their stems move consecutively and their branches move consecutively at the same time.
Consecutive stems from one pair of pillars and consecutive branches from another pair cannot be spliced together. One matching layer alone is not a dual link.
- Name both complete pillars before comparing them.
- Verify stem order and branch order independently.
Noble pairs and qi direction are source-specific refinements
The passage adds noble-branch associations and calls the configuration a linked-pearl fortune spirit. These labels do not replace the basic complete-pillar test.
Its Bing-Yin and Ding-Mao sentence distinguishes receding from advancing qi by order, but does not resolve every reversal, gap, duplicate or pillar-position case.
- Keep noble-branch evidence separate from adjacency.
- Leave unsupported direction cases unclassified.
OpenFate preserves the pillars and standard relationships
The engine can display the four actual pillars, their sexagenary positions and existing stem or branch interactions.
There is no Stem-Branch Dual Link detector. The article adds no virtual pillar, fortune spirit, interaction override, score or saved-report change.
- Use only actual pillar identities and positions.
- No virtual link, noble score or relationship suppression.
A linked sequence cannot prove reputation or life outcomes
The source praises linked pearls and says other sha can be suppressed. That language is not empirical evidence of protection or success.
Do not infer fame, rank, wealth, promotion, morality, relationships, safety, health or lifespan. Preserve direct evidence for every consequential decision.
- No fame, rank, promotion or wealth guarantee.
- No protection, relationship, health or lifespan prediction.
