涧下水 · Water in the Ravine

jiàn xià shuǐ · the Na Yin of 丙子 and 丁丑

涧下水 Water in the Ravine, jiàn xià shuǐ, is the Na Yin of the pillars 丙子 and 丁丑: a Water element with an image of its own, one of the thirty Na Yin of the sixty-pillar cycle. Any pillar of a chart, and any day in the almanac, that is 丙子 or 丁丑 carries it.

Na Yin 纳音, the "received sound", gives each pair of pillars in the sixty-cycle an element and an image of its own. It is read alongside the elements of the stem and branch, not instead of them, and the element it names can differ from both.
