性格Wu Yin personality
Wu Yin is a forested mountain with a tiger in it: solid earth carrying strong pressure. These people are brave, dignified and enterprising, often rising through challenge and responsibility. They respect strength. Rest and delegation keep the pressure productive instead of exhausting.
坐星Sitting on Seven Killings
You sit on the star of pressure and power: driven, brave and decisive, often at your best under challenge. Stress is part of the package.

纳音Nayin: Earth on the City Wall
Each pair of pillars shares one of 30 Nayin, or "sound" elements. Wu Yin belongs to Earth on the City Wall, pictured as earth on a city wall: protective, structured, built to last. 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 Wu 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 Wu Yin is Gui Hai (癸亥): 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 Ren Shen (壬申): 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
Wu Yin belongs to the Jia Xu (甲戌) decade (旬), whose void branches are Shen and You (申酉: Monkey, Rooster). Traditionally, years and months of these branches are said to make plans feel less solid. The next such years: 2028, 2029, 2040, 2041.
