姚萇
In 357, Fu Jiān overthrew the cruel and whimsical Fu Sheng (who had, in addition to many others, put Fu Huangmei to death even after his great victory) and took the throne himself. Sometime early in his reign, Fu Jiān made Yao Chang a general. The first campaign in which he was mentioned by name was in 366, when he assisted Wang Meng in an attack on Jin's Jing Province (荊州, modern Hunan and central and southern Hubei). In 367, he again assisted Wang Meng in attacking the rebels in modern eastern Gansu, who were led by the Qiang general Lian Qi (斂岐), whose subordinates were originally all Yao Yizhong's subordinates and therefore surrendered to him readily. Fu Jiān made him the governor of Longdong Commandery (隴東, roughly modern Baoji, Shaanxi). In 371, he was part of the campaign against Chouchi's ruler Yang Cuan (楊篡), and in 373, after Former Qin seized the modern Sichuan, Chongqing, and southern Shaanxi from Jin, Yao Chang was made the governor of Ning Province (寧州, modern southern Sichuan). In 376, Yao Chang also assisted Gou Chang (苟萇) in Former Qin's conquest of Former Liang, and in 378 involved in the sieged against the Jin city Xiangyang (襄陽, in modern Xiangfan, Hubei). Sometime during Fu Jiān's reign, he created Yao Chang the Marquess of Yidu.
