庚申 in the San Ming Tong Hui (三命通會)
By Wan Minying (Ming dynasty), chapter one, quoted from Chinese Wikisource; translations are ours.
Image, from the list of the sixty pillars
庚申……榴花
庚申: pomegranate blossom.
Why its Na Yin is called 石榴木, from 「论纳音取象」
木居金地，其味成辛…他木至午而死，惟此木至午而旺
Wood sits on metal ground and its taste turns pungent; other trees die at 午, but this one thrives there.
Its Na Yin against the facing one, 松柏木 (庚寅 and 辛卯)
松柏石榴，一坚一辛，性味迥异也
Pine and Pomegranate: one firm, one pungent, quite different in nature and flavor.

FAQ
Is 庚申 a good or bad pillar?
Not on its own; that depends on the whole chart, which this site does not read. Structurally, Geng is rooted in 申, which clashes with 寅 and combines with 巳.
What is the Na Yin of Geng Shen?
Pomegranate Wood (石榴木), which Geng Shen shares with 辛酉 Xin You; the Na Yin names go in pairs, 30 for the 60 pillars. The San Ming Tong Hui explains how the name was chosen in its 论纳音取象 section, quoted above.
Which years are Geng Shen (庚申) years?
Between 1900 and 2100: 1920, 1980, 2040, 2100. Each starts at Lichun, around February 4, not on January 1. Under the Chinese New Year rule the same years are the Year of the Yang Metal Monkey.
