性格Yi Hai personality
Yi Hai is a soft plant carried by deep water: nourished, flexible and kind. These people are gentle, intuitive and generous, often drawn to learning, healing or spiritual subjects. They adapt easily and are easy to like. They need firm boundaries so others do not take their kindness for granted.
坐星Sitting on Direct Resource
You sit on the star of support and learning: thoughtful, studious and protected, with a gift for absorbing knowledge and care.
长生Life stage: Death
Measured on the 12-phase cycle, 乙 on 亥 is at Death: stillness: thoughtful, focused, drawn to depth over display.
纳音Nayin: Fire on the Mountaintop
Each pair of pillars shares one of 30 Nayin, or "sound" elements. Yi Hai belongs to Fire on the Mountaintop, pictured as fire on a mountaintop: visible from afar, brilliant but short-lived. 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 Yi Hai it holds the Pig, which traditionally harmonises with the Tiger (six harmony) and the Rabbit and Goat (three harmony), and clashes with the Snake.
The most harmonious day pillar for Yi Hai is Geng Yin (庚寅): its stem combines with yours and its branch forms a six-harmony pair (天合地合). The most challenging are Ji Si (己巳) and Xin Si (辛巳): 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
Yi Hai 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.
