Grand Duke Combination.Alignment creates access—not certainty.
Grand Duke Combination (歲合), or Sui He, describes the Earthly Branch in Six-Harmony relationship with the governing year Branch. It is associated with cooperation, mediation, useful alliances and access through people or institutions.
The year may open a channel—but the agreement still needs substance.
Sui He is the Branch that pairs with the year’s governing Branch through the fixed Six-Harmony relationships. It can highlight collaboration, support from influential people, negotiation, forgiveness, approvals or access to organised resources.
Yet 合 means joining or binding, not unconditional good fortune. A connection may be helpful, demanding, politically sensitive or absorbing. Read what is being joined, why it matters and whether the terms are workable.
This page treats Grand Duke Combination as an annual marker. Anchor it to the year being examined, then test the paired Branch against the natal chart and real events.
Six fixed pairs govern all twelve branches.
Find the governing Year Branch and read across to its Six-Harmony partner.

From annual Branch to practical evidence
Connection is a mechanism. Outcome depends on what it binds.
No guaranteed benefactor
The marker does not promise rescue, favour or powerful supporters.
No automatic harmony
Combination can mean attachment, obligation or absorption as well as cooperation.
No approval guarantee
Licences, grants and contracts still require eligibility and evidence.
No trust shortcut
Association cannot replace due diligence, boundaries or written terms.
No single-star reading
Read the annual Stem, natal structure and all relevant Branch interactions.
No passive waiting
Potential support becomes useful only through competent action and follow-through.

Is Grand Duke Combination always favourable?
No. It indicates joining or coordination; the result depends on the complete chart, timing and real arrangement.
Is it calculated from the birth year?
This page uses the governing year being examined as the anchor, then checks its Six-Harmony partner against the natal chart.
Does it guarantee help from powerful people?
No. It may highlight access or cooperation, but support must be verified through actual behaviour and authority.
Is this the same as Grand Duke or Year Breaker?
No. Grand Duke marks the governing year Branch; Year Breaker is its opposition; Sui He is its Six-Harmony partner.
Can it support contracts or grants?
It may describe a more cooperative climate, but eligibility, documentation and enforceable terms remain decisive.
