姚興
In 414, Yao Bi made several attempts to be made crown prince by having officials close to him suggesting Yao Xing to replace Yao Hong with him. Yao Xing refused, but did not rebuke Yao Bi. Yao Xing grew seriously ill that year, and Yao Bi planned a coup to take over. His brother Yao Yu revealed his plot to the other brothers Yao Yi, Yao Huang, Yao Chen, and Yao Xuan, who mobilized their own forces to be ready to attack Yao Bi if necessary. Yao Xing was forced to relieve Yao Bi of his posts, and the other sons demobilized and arrived at Chang'an for an official visit. The sons accused Yao Bi of many crimes, but Yao Xing took no further action. Indeed, in 415, Yao Bi retaliated by falsely accusing Yao Xuan of crimes, and Yao Xing arrested Yao Xuan.
