Yao Xing
In 416, Yao Xing went on a trip to Huayin (華陰), near Chang'an, and fell ill on the trip and headed back to Chang'an. His attendant Yin Chong (尹沖) -- one of Yao Bi's supporters—planned to then assassinate Yao Hong as Yao Hong would come out of the city to welcome Yao Xing. Yao Hong's supporters received news of this and persuaded Yao Hong not to come out to welcome Yao Xing. Yin's assistant Yao Shami (姚沙彌) then tried to persuade Yin to take Yao Xing and join with Yao Bi to seize power, but Yin hesitated and did not do so. Once Yao Xing returned to the Chang'an palace, he transferred power to Yao Hong and ordered Yao Bi arrested. Meanwhile, Yao Xing's son Yao Geng'er (姚耕兒), believing that Yao Xing had died, persuaded his brother Yao Yin (姚愔) the Duke of Nanyang to start a coup, and Yao Yin joined with Yin Chong (perhaps in anticipatory support of Yao Bi's claims) to attack the palace, battling with Yao Hong's troops. Yao Xing, despite his illness, made an appearance and announced an edict ordering Yao Bi to commit suicide. As soon as Yao Yin's troops saw Yao Xing, they abandoned Yao Yin. That night, Yao Xing entrusted Yao Hong's administration to his brother Yao Shao (姚紹) the Duke of Dongping, Liang Xi (梁喜), Yin Zhao (尹昭), and Lian Manwei (斂曼嵬), and he died the next day. Yao Hong succeeded him, but he soon had to face even more challenges from his brothers and cousins as well as attacks by Xia and Jin, and by 417 Later Qin had fallen to Jin.
