Day Master

辛 Xin: the Yin Metal Day Master

Refined, precise, and sensitive, like a polished gemstone.

By the Daoly team · Updated November 2026

What Yin Metal is like in BaZi

辛 is imagined as jewelry or finely worked metal. Xin charts are often described as discerning and elegant, with high standards and a strong awareness of how things appear.

Common strengths

  • Taste and precision
  • Careful judgment
  • Self-respect

Common blind spots

  • Perfectionism
  • Taking criticism to heart
  • Holding others to private standards

What this Day Master tends to need

Readings often prefer clean Water to polish the jewel, with care that heavy Earth does not bury it.

A Day Master's needs depend on season and on the rest of the chart, so two people with the same Day Master can need different things.

Key relationships

Xin combines with 丙 Bing (Yang Fire). Its output is Water, its wealth is Wood, its pressure comes from Fire, and its support comes from Earth.

See how these relationships become roles in the Ten Gods guide.
