Yin-Hai Harmony into Wood (寅亥合木)
Understand the Yin-Hai Six-Harmony pair, the Wood tendency, seasonal and root support, and its overlap with break, harm, trine, and meeting structures.
Overview
Yin–Hai Harmony (寅亥合木) joins two branches with a strong Wood pathway: Hai supports Wood and Yin carries primary Wood. The pair may reinforce Wood when season, roots, exposure, and access agree. It also appears in some break conventions and can enter Wood trines or seasonal meetings, so no single label may erase the wider network.

Establish the fixed harmony pair
Record the positions of Yin and Hai and whether either comes from timing.
The pair signals contact; both branches and their hidden stems remain part of the chart.
- Name both pillars.
- Keep natal and timing layers separate.
Assess the Wood route
Spring command, Wood roots, and exposed Wood can make the relation more coherent.
Strong Metal, damage, or a disconnected route may prevent full phase conversion.
- Test season and roots.
- Publish counterforce.
Retain simultaneous branch structures
Yin can join Fire trines or spring meetings; Hai can join Wood trines, northern meetings, and Si clash.
Where a school also calls Yin–Hai a break, disclose both labels and compare actual force.
- Do not hide overlaps.
- Label school differences.
Do not equate Wood harmony with relationship success
寅亥合木 cannot prove affection, creativity, growth, marriage, travel, or wealth.
Interpret it as a structural route and verify life claims independently.
- No positive stereotype.
- No event certainty.
