Pinyin
liǎng yáng hé míng
Simplified
两阳合明
Literal
兩 liǎng — two; 陽 yáng — yang; 合 hé — to join, to put together; 明 míng — bright. The four graphs name 陽明 from something the qi does rather than from a position: two yangs brought together make the brightness.
Shuowen
**《說文》:合,合口也;明,照也**。**「兩陽合明」本篇2見**;**一見於答「陽明何謂」之問,一見於釋「明」之句**;**「陽明」本篇15見,為六氣之一,司天在泉與所至之文皆有其目**;**「明」字本篇29見,又為間氣一化之名(間氣爲明化),字同而用異**

In brief

The name of 陽明, given by the chapter as a piece of arithmetic on the two yang within it: 帝曰:陽明何謂也?歧伯曰:兩陽合明也. The answer turns the name into a description — the brightness of 陽明 is what comes of two yangs joining — and the chapter then uses the same words a second time for something larger. Asked 幽明何如? it answers 兩陰交盡,故曰幽;兩陽合明,故曰明,幽明之配,寒暑之異也, so that 兩陽合明 becomes the name of the bright half of the year as 兩陰交盡 is the name of the dark. The pair is used as the ground of the 分至 that follow, and it is one of three places where the chapter explains a qi’s name instead of merely using it.

Huang Di said: good. I wish to hear what is meant by the three of yin and yang. Qi Bo said: the qi has much and little, and their uses differ. Huang Di said: what is meant by yang brightness? Qi Bo said: two yangs joined make brightness. Huang Di said: what of ceasing yin? Qi Bo said: two yins crossing come to an end. Huang Di said: the qi has much and little, illness has abundance and decline, treatment has slowness and urgency, and formulas have great and small; I wish to hear the essentials of it. Qi Bo said: the qi has high and low, illness has far and near, the signs have inner and outer, and treatment has light and heavy, each suiting where it arrives. The Great Essentials says: one sovereign with two ministers is the rule of the odd; two sovereigns with four ministers is the rule of the even; two sovereigns with three ministers is the rule of the odd; two sovereigns with six ministers is the rule of the even.
