性格Geng Wu personality
Geng Wu is raw metal shaped by fire. Pressure refines it, so these people often grow strongest through discipline, responsibility and public roles. They are honourable, direct and charismatic, with a sharp sense of justice. Their temper can flare fast, and they do well when they choose their battles.

纳音Nayin: Earth by the Roadside
Each pair of pillars shares one of 30 Nayin, or "sound" elements. Geng Wu belongs to Earth by the Roadside, pictured as earth beside the road: useful, humble ground that supports others. Nayin is an older layer of Chinese astrology and is read as a background image, not as your Day Master's element.

In BaZi the day branch is the spouse palace. For Geng Wu it holds the Horse, which traditionally harmonises with the Goat (six harmony) and the Dog and Tiger (three harmony), and clashes with the Rat.
The most harmonious day pillar for Geng Wu is Yi Wei (乙未): its stem combines with yours and its branch forms a six-harmony pair (天合地合). The most challenging are Jia Zi (甲子) and Bing Zi (丙子): stem against stem and branch against branch (天克地冲). Other pillars in your chart matter more than this single pairing.
空亡Void branches
Geng Wu belongs to the Jia Zi (甲子) decade (旬), whose void branches are Xu and Hai (戌亥: Dog, Pig). Traditionally, years and months of these branches are said to make plans feel less solid. The next such years: 2030, 2031, 2042, 2043.
