趙璧（上直小反切韻郡名也下必益反晏子云曾子將行晏子送之曰和氏璧井里之朴良工修之則為國寚爾雅云肉信好謂之璧郭注肉邊也好孔也）。

Zhaobi 趙璧 (The first character has the fanqie phonetic spelling [zh- + -ào > zh-] zhí xiǎo 反. The Qieyun says it is the name of a commandery. The second character has the fanqie phonetic spelling [b- + -ì > b-] bì yì 反. Yanzi says: "When Zengzi was about to depart, Yanzi saw him off, saying: 'The jade disc of the He clan is an unworked stone in an ordinary village; when a skilled artisan polishes it, it becomes a national treasure.'" The Erya says: "When the solid portion (rou 肉) is twice the size of the perforation (hao 好), it is called a bi 璧." Guo's commentary states: "Rou is the border; hao is the hole").
