Rén

Size comes first with 壬 (Rén), yang water and the ninth stem. 滴天髓 and 淵海子平 both call it 汪洋, a vast expanse, and the second adds that it takes in the hundred rivers. The commentary refuses to treat it apart from 癸: it calls 壬 the source of that stem and says rivers and rain are one substance. 三命通會 卷二 goes a different way and names it cloud above and marsh below.

Water draining metal is the generating cycle seen from the child's side: metal feeds water, so water spends metal's strength. 周流不滯, circulating and never stuck, sits oddly beside 三命通會, whose paragraph on this stem calls 壬 死水, still water in a pond, as a technical label for firm, yang water. The fierce middle line needs 申, 子, 辰 and a visible 癸, at which point the commentary says nothing can hold it back. The last line turns tender, with 壬 joining 丁 in a way the commentary calls a husband's duty and a lord's kindness.

Seen from 壬, the 癸 that lends force to that middle line is a Rob Wealth, 丁 is Direct Wealth and 戊 is Seven Killings. 三命通會 likes yang earth as the bank that gives this water a channel, which makes that last name sound much less grim. The month and the branches decide which of the verse's moods applies, and summer brings its own clause, where the commentary has 壬 steaming with the earth of 巳, 午 and 未 until it falls as rain. The restless, roving 壬 character belongs to modern popular writing.
