纳音Nayin: Pine and Cypress Wood
Each pair of pillars shares one of 30 Nayin, or "sound" elements. Geng Yin belongs to Pine and Cypress Wood, pictured as pine and cypress: evergreen endurance through cold seasons. 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 Yin it holds the Tiger, which traditionally harmonises with the Pig (six harmony) and the Horse and Dog (three harmony), and clashes with the Monkey.
The most harmonious day pillar for Geng Yin is Yi Hai (乙亥): its stem combines with yours and its branch forms a six-harmony pair (天合地合). The most challenging are Jia Shen (甲申) and Bing Shen (丙申): 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 Yin belongs to the Jia Shen (甲申) decade (旬), whose void branches are Wu and Wei (午未: Horse, Goat). Traditionally, years and months of these branches are said to make plans feel less solid. The next such years: 2026, 2027, 2038, 2039.
