Xin You · 辛酉
Xin You pairs 辛, a Yin Metal Day Master, with 酉 (the Rooster), a Metal branch. Read the upper character first, then the branch and the stems it contains.
The Day Master on top
Yin Metal · 辛 — Xin (辛) is Yin Metal. Jewelry and finely worked metal provide common images, emphasizing finish, edges, and detail. They explain a symbolic category rather than certify someone's taste or precision.

酉 (the Rooster) contains 辛 in the traditional hidden-stem table. Each stem receives a ten-god label by comparing its element and polarity with 辛. The day branch is also traditionally called the spouse palace; that name does not identify a partner's character.

Na Yin
Xin You has the Na Yin label 石榴木, "Pomegranate Wood". Thirty names are shared by the sixty pairs. This is a separate classification from the Day Master's element.
Stage of the cycle
Taking office · This is the traditional twelve-stage label for the day stem 辛 in branch 酉. Read it as a stem–branch classification, not a person's age or state of health.
The two unpaired branches (Xun Kong)
辛酉 belongs to the ten-pair group beginning with 甲寅. Its ten stems pair with ten of the twelve branches, leaving 子丑 outside that group. Those two are called Xun Kong, or "void branches".
Keep the Day Master, change the branch
These day pillars share the same upper character. Compare their hidden stems to see why a Day Master alone cannot describe all the chart relationships.
