《资治通鉴·晋纪·晋纪三十六》
姚兴对待晋公姚绪和姚硕德，都用家里亲人的礼节，车马、衣服、珍玩等也都先送给两位叔父，然后自己才留用差一点的。国家的大政方针，都事先请示他们之后再决定。
兴事晋公绪及硕德皆如家人礼，车马、服玩，先奉二叔，而自服其次，国家大政，皆咨而后行。
Yao Xing treated the Jin Duke Yao Xu and Yao Shuo with the etiquette of family relatives. He also gave the chariots, clothes, and valuables to his two uncles first and kept the slightly inferior ones for himself. All the major national policies were decided after they were consulted.
