《汉书·传·翟方进传》
王莽又下韶说： 听说古时候讨伐不敬的人，要杀死那些敌人中特别凶恶的堆积起来表彰军功，封土为垒以大量陈尸，因此有做成像高丘城楼般的形状来警戒那些邪恶的人。
而下诏曰： 盖闻古者伐不敬，取其鲸鲵筑武军，封以为大戮，于是乎有京观以惩淫慝。
Wang Mang also issued an imperial edict, saying, "I have heard that in ancient times, when punishing those who were disrespectful, the most violent of the enemies were killed and piled up as a display of military achievement, and earth was piled up to form a mound as a warning to evildoers."
