性格Jia Zi personality

Jia Zi is the first of the sixty pillars: a young tree rooted in cold, nourishing water. People with this day pillar are often bright, studious and gently idealistic, with a quiet charm others notice. They learn fast and like to be taken seriously; the challenge is acting on ideas before the season changes.

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: Bath

Measured on the 12-phase cycle, 甲 on 子 is at Bath: a young person learning about the world: charming, curious, emotionally changeable.

纳音Nayin: Gold in the Sea

Each pair of pillars shares one of 30 Nayin, or "sound" elements. Jia Zi belongs to Gold in the Sea, pictured as precious metal hidden under the waves: value that shows once it surfaces. Nayin is an older layer of Chinese astrology and is read as a background image, not as your Day Master's element.

婚恋Love and the spouse palace

In BaZi the day branch is the spouse palace. For Jia Zi it holds the Rat, which traditionally harmonises with the Ox (six harmony) and the Dragon and Monkey (three harmony), and clashes with the Horse.

The most harmonious day pillar for Jia Zi is Ji Chou (己丑): its stem combines with yours and its branch forms a six-harmony pair (天合地合). The most challenging are Wu Wu (戊午) and Geng Wu (庚午): stem against stem and branch against branch (天克地冲). Other pillars in your chart matter more than this single pairing.

Jia Zi 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.
