Fire placed on water: 子 controls 丙 on the element count, one of the plainest cases in the sixty of a branch overruling its stem. The table still gives 丙 the stage Conception at 子, and 五行大義 had fire there long before, 胎於子, conceived at 子. 三命通會 describes that seat as the moment when the energies of heaven and earth meet and something first stirs in the ground.

The only stem commonly listed in 子 is 癸. From 丙 it is Direct Officer, water controlling fire at opposite polarity. Add the seven days of 壬 that 三命通會 puts in this branch and a Seven Killings reading appears as well, since 壬 and 丙 are both yang.

澗下水, Water Beneath the Ravine, is the 納音, yet the 三命通會 卷一 entry for 丙子 never mentions a ravine. It says 江湖, rivers and lakes, and 喜木及土, pleased by wood and earth. The usual 納音 name and this book's picture differ, and both are kept here.
