姚萇
As Fu Jian grew older, he received some military responsibilities under his cousin Fu Sheng, who succeeded Former Qin's founding emperor after his death in 355. In 357, when Yao Xiang (), a major Qiang chief, attacked Former Qin, hoping to conquer it, Fu Jian was one of the generals who fought him and defeated him, capturing and executing him on the battlefield. Yao Xiang's brother Yao Chang surrendered. Initially, the lead general Fu Huangmei () the Prince of Guangping wanted to put Yao Chang to death, but Fu Jian interceded, and Yao Chang was spared.
