《后汉书·列传·西域传》
臣磐得知后，向月氏王请求说： 安国没有儿子，种族衰弱，如果立娘家人，我是遣腹的叔父，我应该当国王。 
臣磐闻之，请月氏王曰： 安国无子，种人微弱，若立母氏，我乃遗腹叔父也，我当为王。 
When Xianfu heard about this, he asked the King of Yuezhi, "Anguo had no son, and his race was weakened. If his maternal family is made the king, I am Xianfu's paternal uncle, and I should be the king."
