xin-hai day pillar

亥, the Pig, is a water branch, and the yin metal above it is the parent in that relation. Against 辛 the two hidden stems in this site's table are 壬, the Hurting Officer, and 甲, Direct Wealth, both yang and both at opposite polarity to the day master. 三命通會 also counts a short spell of 戊 in this branch, which would add a Direct Resource to the list.

钟鼎实物 is the phrase in 三命通會 卷一: bells and tripods, solid things. Those heavy bronzes sit oddly beside the 納音 name Hairpin and Bracelet Gold, and the entry says this metal likes wood, fire and earth.

This pillar sits at Bath, 沐浴. 辛 has its Growth at 子 and moves backward by one branch to reach 亥, under the reversal that 神峰通考 sums up in four characters, 阳顺阴逆, yang forward and yin in reverse.
