性格Ding Si personality

坐星Sitting on Rob Wealth (Rival)
You sit on a rival of your own element: competitive, bold and generous with friends, willing to take risks. Money and loyalty can get mixed up.

纳音Nayin: Earth in the Sand
Each pair of pillars shares one of 30 Nayin, or "sound" elements. Ding Si belongs to Earth in the Sand, pictured as earth in the sand: fine, shifting ground that settles over time. 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 Ding Si it holds the Snake, which traditionally harmonises with the Monkey (six harmony) and the Rooster and Ox (three harmony), and clashes with the Pig.
The most harmonious day pillar for Ding Si is Ren Shen (壬申): its stem combines with yours and its branch forms a six-harmony pair (天合地合). The most challenging are Xin Hai (辛亥) and Gui Hai (癸亥): stem against stem and branch against branch (天克地冲). Other pillars in your chart matter more than this single pairing.

Ding Si belongs to the Jia Yin (甲寅) decade (旬), whose void branches are Zi and Chou (子丑: Rat, Ox). Traditionally, years and months of these branches are said to make plans feel less solid. The next such years: 2032, 2033, 2044, 2045.
