八埏（下演栴反漢書音義延地極邊際也古今正字從土延聲傳文從手非也）。

八埏 [the eight extremities]: The second character is read with the fanqie yan + zhan (yán). The commentary on the Hanshu says: 'Yan (埏) means the extreme borders of the earth.' The Gujin zhengzi says it is composed of the [semantic] radical 'earth' (土) and the sound yan (延). In the transmitted text it is written with the [radical] 'hand' (手), which is incorrect.
