髆傭（上音愽考聲股上脾也說文云肩髆也從骨專聲經文從肉作膊音普博反謂乾脯也非經義下丑龍反鄭箋毛詩云滽均也說文云均直也從人庸聲有作𦟛俗用字亦通也）。

髆傭 [Shoulders well-proportioned]: The upper [character] has the sound 愽 (bó); the Kaosheng says, “The upper part of the thigh, the hip.” The Shuowen says, “The shoulder blade (髆); it derives from 骨 with the phonetic 專.” In the sūtra text it derives from 肉 as 膊, with the sound 普博 (pǔ + bó = pō), meaning dried meat, which is not the meaning here. The lower [character] has the fanqie 丑龍 (chǒu + lóng = chōng); Zheng's commentary to the Mao Shijing says, “滽 means well-proportioned.” The Shuowen says, “Well-proportioned and straight; it derives from 人 with the phonetic 庸.” Some write 𦟛, which is also commonly accepted as a vulgar character.
