Pinyin
fú jiǎ
Simplified
虙瘕
Literal
虙瘕 fú jiǎ — a mass that hides. 虙 is an old graph read fú and glossed as 伏, to lie concealed; the base text writes 虙 and the site keeps it. 瘕 is the Suwen's word for a lump that comes and goes, a mass with no fixed seat — the same graph as in chapter 32. The chapter names it together with 沈 as what the small intestine produces when it shifts heat into the large intestine.

《說文解字》：瘕，女病也——**「瘕」者，腹中聚散無常之塊**；**「虙」字《說文》所無，古書假為「伏」（「伏」讀 fú）**。「虙」讀 fú，本篇惟此一見，**通「伏」，不作「伏」**；「瘕」讀 jiǎ，本篇惟此一見，**與本站第三十二篇「瘕」同字**。

In brief

A concealed, shifting abdominal mass, named with 沈 as what the small intestine produces when it passes heat to the large intestine. 虙 is the base-text graph, glossed as 伏.
