《元史·列传·卷九》
太祖十八年春，木华黎卒于闻喜县下马村，平阳重地令按扎儿镇守。太宗二年，蒙军孛鲁部由云中围攻卫州，金守将武仙退保潞州东十余里之原上。孛鲁进军至沁州以南，为金将乞石烈所败，辎重人口皆陷没，按扎儿妻奴丹氏亦被俘。金主闻按扎儿威名，令奴丹氏招降其夫。
至钧州三峰山，金将完颜合达引兵十五万来战，俘其同佥移剌不花等，悉诛之。
In the spring of the eighteenth year of Taizu's reign, Mu Huali died in Xiacun, Wenxi County. Anzha was ordered to guard the important land of Pingyang. In the second year of Taizong's reign, the Mongol army's Bolü tribe besieged Weizhou from Yunchong. The Jin general Wu Xian retreated to a plain ten miles east of Luzhou. Bolü advanced to the south of Qinzhou, but was defeated by the Jin general Qishilie. Bolü's supplies and people were all lost, and Anzha's wife, Nu Dan, was also captured. When the Jin emperor heard of Anzha's reputation, he ordered Nu Dan to persuade her husband to surrender.
