Hexagram 47 is the upside-down (Pang tong gua) of hexagram 48, and 47.4 corresponds to 48.3.
Hexagram 28 does not visibly change when you turn it upside-down. Or does it???
Maybe the sagging ridgepole of line 3 corresponds upside-down with the eminent ridgepole of line 4.
In the Mirrors 28.3, 28.4, 47.3 and 48.4 are all four together one 'unit'. Mirrors and reflections of each other. Every mirror has a 'theme', something which connects all four. In this mirror the theme has to do with the strength of stone and poles/ treetrunks. Organic and anorganic strength.
