Metal is not a personality type but a checkable distribution: its exact place among the ten stems, twelve branches, hidden stems and the combination tables, all computed.

Stems Yang Metal (yang)、 Yin Metal (yin)
Main-qi branches Monkey Rooster (2)
Hidden in5 of 12 branches contain Metal in their hidden stems
Trine Snake Rooster Ox (Metal trine)
Seasonal meeting Monkey Rooster Dog (West)
Growth starts Yang Metal starts at Snake; Yin Metal starts at Rat

The cycle: relations to the other four elements

The direction of each relation comes from the engine ten-gods function; this page does not retype a second cycle table.

On the stems: the two gan and their five-harmony pairings

Two of the ten stems are Metal, one yang and one yin. Each has one five-harmony pairing; the resulting element comes from the engine table and is never Metal itself.

Yang Metal + Yin Woodcombines into Metal
Yin Metal + Yang Firecombines into Water

On the branches: main qi, the trine and the meeting

The Si-You-Chou trine forms the Metal frame, and its first branch is exactly the growth start of 庚 (cross-checked against the engine stage table). The West meeting Shen-You-Xu runs by direction: its first two branches carry Metal as main qi, and the closing branch 戌 is the tomb of the 火 trine.

Why this page has no personality reading

Most "element personality" pages online print the same templated traits. This page only prints numbers you can check against the engine: which stems, which branches, how often hidden, and how the cycle runs. Trait tables are not facts, so this site does not make them.

FAQ

Why is there no personality reading on this page?
Trait tables are not checkable facts. This page only prints computed numbers: two stems, main-qi branches, hidden-stem presence in 5 of 12 branches, and cycle directions from the engine ten-gods function. Every cell traces back to the engine.
Which two stems are Metal, and what do they combine into?
庚 pairs with 乙, combining into 金; 辛 pairs with 丙, combining into 水. The results come from the engine combination table and are never Metal itself.
How does the Si-You-Chou trine work?
Its first branch is exactly the growth start of Geng, the middle branch is the peak, and the closing branch is the tomb — each item cross-checked against the engine stage table, not copied.
Where does Metal hide inside the twelve branches?
Main qi: 申酉; middle: 巳戌; residual: 丑 — 5 of 12 branches.
Why do Geng and Xin start at different branches?
Yang stems run forward, yin stems run backward; the engine stage table gives Geng starts at Si, Xin starts at Zi. Two different starts are a structural fact of the table, not a contradiction.
