Chinese character 胊

It names the bent part of dried meat.

In classical Chinese food vocabulary, 胊 can name the curved section of dried meat or dried meat itself. The early Chinese dictionary Shuowen Jiezi records this food sense.

How did 胊 reach place names?

It appears in early food vocabulary and later in place names.

The Shuowen Jiezi, an early Chinese dictionary, defines 胊 as a term for dried meat; ritual texts also use it in placement instructions. In 左胊右末, the bent part goes on the left and the straight end on the right.

Later dictionaries also give senses related to bending or curvature. Historical records use 胊 in names such as 胊山 and 临胊, so the surrounding phrase helps identify a food term from a place name.

Is 胊 the same as 朐?

No: dictionaries link their meanings, but the source form matters.

Chinese dictionaries connect 胊 and 朐 with dried-meat and bend-related vocabulary. A Unicode unification record classifies them as non-cognate ideographs, so that lexical link does not establish a shared origin. Follow the form used in the text you are reading.
