ding-si day pillar

Yin fire meets a fire branch in 丁巳, and 巳, the Snake, is one branch whose contents the three main works agree on. To 丁, the stems inside are 丙, Rob Wealth; 庚, Direct Wealth; and 戊, the Hurting Officer. The name for that first stem is unsteady from the yin side: 淵海子平 calls a yin stem meeting its yang twin 劫財, and the tables of 神峰通考 call it 敗財.

A surprise arrives in 三命通會 卷一, which gives 土之沮, earth gone boggy, for a pair with so much fire in it. Fire heads the list of what that wet ground likes. The 納音 is Earth in the Sand, shared with 丙辰.

Run 丁 in reverse from 酉 and the fifth place, 巳, is Emperor, 帝旺. Its yang partner 丙, counted forward, reaches only Officer on this branch, which shows how much the placement leans on the reversal rule.
