城塹（上城字正體中從丁世本云𩩌作城淮南子玄𩩌作九仞之城七尺曰仞說文從士成聲下妾焰反字書塹城隍也說文從土斬聲）。

City walls and moats (城塹: the correct form of the upper character, 城, has ding [丁] in the middle. The Shiben says: 'Gun constructed the city walls.' The Huainanzi says: 'Xuangun constructed city walls of nine ren.' Seven feet [chi] is called a ren. The Shuowen says: 'It is derived from "earth" [土] and phonetic cheng [成].' The lower character has the fanqie qie-yan [qiàn]. Dictionaries say: 'A 塹 is a city moat.' The Shuowen says: 'It is derived from "earth" [土] and phonetic zhan [斬].').
