Pinyin: fēi yáng
Simplified: 飞阳
Literal: 飛陽 fēi yáng — flying yang, the vessel that later acupuncture knows as 飛揚, the network point of the foot greater yang some seven inches above the ankle. Chapter 41 names it once: the painful spot feels as though something had brushed it, and at its worst the patient grieves and is afraid. It is needled five inches above the inner ankle, in front of lesser yin, where it meets the yin link vessel. Wang Bing identifies the two names as one, and the chapter's own description — a vessel of the foot that runs up to meet a link vessel — fits the later point well enough to make the identification safe to record and unsafe to insist on.
Shuowen: 《說文解字》：飛，鳥翥也——**象鳥舉翅之形**；**「陽」（「陽」讀 yáng）从阜昜聲，高明也**。「飛」讀 fēi，**本篇2見**，**皆在「飛陽之脉」一名**；**「飛陽之脉」2見**。**王冰註：飛陽，謂飛揚，足太陽之絡**——**後世作「飛揚」，本篇作「飛陽」，字異而脈同**。「悲」讀 bēi、「恐」讀 kǒng、**「甚則悲以恐」與上文「善恐」相承**；「會」讀 huì**「與陰維之會」讀 huì**。

In brief

Flying yang — the vessel that later acupuncture calls 飛揚, the network point of the foot greater yang. Chapter 41 gives it a brushed sensation at the painful spot and, at its worst, grief and fear; it is needled above the inner ankle where it meets the yin link vessel.
