姚兴
In 412, Qifu Gangui was assassinated by his nephew Qifu Gongfu (乞伏公府), the son of the founding king Qifu Guoren. Many Later Qin officials try to persuade Yao Xing to take the opportunity, as Qifu Gongfu and Qifu Chipan battled for control of the state, to attack Western Qin. Yao Xing refused, believing it improper to attack a state that was still mourning.
