《北齐书·本纪·卷一》
过了不长时间，神武再次派遣刘贵向尔朱兆提出请求，以并、肆等地连年天灾，迫使降户挖掘黄鼠作为充饥之食，所以人人面有菜色，白白玷污了人家的土地，希望让这批人前往山东谋生，等待温饱之后再作安置，尔朱兆接受了神武的建议。
居无何，又使刘贵请兆，以并、肆频岁霜旱，降户掘黄鼠而食之，皆面无谷色，徒污人国土，请令就食山东，待温饱而处分之。兆从其议。
A short time later, Divine Martial sent Liu Gui once again to ask Er Zhuzhao, on the grounds that the recent natural disasters in Bing, Si, and other areas had forced the commoners who came to surrender to dig up yellow rats to fill their stomachs, which resulted in their faces all looking ashen. They looked ghastly and made a mess of his land, so he wanted to let these people go to Shandong to earn a living and wait until they had full bellies before resettling them. Er Zhuzhao adopted Divine Martial’s suggestion.
