Two movements · four fixed relations
What Water gives—and what keeps it in check
Every phase stands in four fixed relations. Neither cycle is a ranking: generating and controlling are both necessary, and a system with only one would run away or seize up.
Where the phase enters a chart
The stems and branches that carry Water
A phase reaches a chart through the ten heavenly stems and twelve earthly branches. Each stem takes one phase in a yang and a yin form; the branches distribute the same five phases across the twelve animals.
01 · Two polarities
Heavenly stems
02 · 2 fixed branches
Earthly branches
These branches fall together in the calendar because water governs winter.
Twelve appearances in sixty positions
Water in the sixty-year cycle
Twelve of the sixty stem-branch pairs take a stem of this phase—one for each branch, alternating yang and yin. Read the records across rather than scanning a table.

A separate named association
The Water sounds
纳音 assigns each pair of pillars one of thirty sounds, each named for an image. Six of them belong to this phase, and a pillar's sound is often a different phase from its stem.
