《元史·列传·卷二十四》
曾与仁宗谈及科举及前代帝王赐姓命氏之事，因赐察罕姓白氏。察罕出生时，夜间天气晴朗，月白如昼，蒙古人谓白为察罕，故名察罕。察罕天性孝友，其在河中田宅，都分给众兄弟，释放许多奴婢为民，所以多称他是有德行的人。
阿礼海牙亦早事武宗、仁宗，为宿卫，以清慎通敏与父兄并见信任。
He once discussed with Emperor Ren Zong about the imperial examination system and the granting of imperial family names to non-royalty by emperors in previous dynasties. As a result, Emperor Ren Zong bestowed the imperial surname of Bai on Chahan. When Chahan was born, it was a clear night with a full moon, and the Mongols called white “chahan,” so he was named Chahan. Chahan was naturally filial and friendly. The farms and houses he owned in He Zhong were all divided up among his brothers, and he freed many of his slaves so they could become regular citizens. Thus, he was often considered to be a virtuous person.
