庚寅 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
庚寅……松柏干节
庚寅: the trunk and knots of pine and cypress.
Why its Na Yin is called 松柏木, from 「论纳音取象」
木居下得其旺，岁寒后凋，取其性之坚也
The wood below is at full strength and, like pine and cypress, is the last to wither in the cold of the year: the image is taken from its firmness.
Its Na Yin against the facing one, 石榴木 (庚申 and 辛酉)
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 庚寅 a good or bad pillar?
Not on its own; that depends on the whole chart, which this site does not read. Structurally, Geng has no root in 寅, which clashes with 申 and combines with 亥.
What is the Na Yin of Geng Yin?
Pine and Cypress Wood (松柏木), which Geng Yin shares with 辛卯 Xin Mao; 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 Yin (庚寅) years?
Between 1900 and 2100: 1950, 2010, 2070. 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 Tiger.
