Each pair of pillars shares one of 30 Nayin, or "sound" elements. Ding Hai belongs to Earth on the Roof, pictured as earth on a roof: shelter for others, quietly essential. 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 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 Ding Hai is Ren Yin (壬寅): its stem combines with yours and its branch forms a six-harmony pair (天合地合). The most challenging are Xin Si (辛巳) and Gui Si (癸巳): stem against stem and branch against branch (天克地冲). Other pillars in your chart matter more than this single pairing.
