雉堞 (Battlements: The upper character has the fanqie 池履 [zhì]. The Zishu says: "雉 means an array." The Gongyang zhuan says: "Five planks make a du; five du make a zhi; one hundred zhi make a city wall." He Xiu says: "Twenty thousand chi." The Kaosheng says: "A section of city wall thirty chi long and ten chi high is called a zhi." The Book of Rites says: "The Son of Heaven's city wall is one thousand zhi"—meaning it has an area accommodating a thousand walls of one hundred zhi. "A duke or marquess has a wall of one hundred zhi, an earl seventy zhi, and a viscount or baron fifty zhi." However, the walls of all feudal lords were left deficient on the southern side, so as to allow for egress, meaning they were intended for dwelling in rather than entrenched defence. The lower character has the fanqie 徒頰 [dié]. Du's commentary on the Zuo zhuan says: "Die means the wall itself; it is the wall set atop [the rampart]." The Shuowen says: "A woman's wall (parapet). It takes its semantic element from 土 (earth) and an abbreviated form of 葉 for its sound").
