What is fixed inside 庚子
Earth on the wall
Earth on the wall becomes the surface and enclosure of a place people inhabit. In a day-pillar reading, it suggests the shaping of an inner setting: boundaries, finish and the distinction between what is shared and what stays within. Its character is domestic rather than monumental, unlike a city wall built to define a whole settlement.

庚子 as a day pillar
Geng’s traditional Metal is strong and responsive to shaping. The Day Master image can describe resolve, clear distinctions and a preference for meeting a problem directly. Refinement matters as much as force: the interpretive question is how determination becomes purposeful action. Fire and Water give the classical discussion different ways of describing that shaping and expression.
庚 above 子
Metal generates Water, so the visible stem feeds the branch phase. The day branch holds Gui 癸 (Hurting Officer) relative to this Day Master.
