Qifu Gangui
In 394, after the death of the Later Qin emperor Yao Chang, Fu Deng prepared a major offensive against Yao Chang's son and successor Yao Xing, and as part of the preparation he requested aid from Qifu Gangui and created Qifu Gangui the Prince of Henan and bestowed on him the nine bestowments. However, Fu Deng's campaign ended in failure, as his forces were defeated by Yao Xing's, and his brother Fu Guang (苻廣) and son Fu Chong abandoned his bases, forcing him to flee into the mountains. He then married his sister the Princess Dongping to Qifu Gangui as his princess and created him the Prince of Liang. Qifu Gangui sent his brother Qifu Yizhou (乞伏益州) to aid Fu Deng, but as Fu Deng came out of the mountains to join Qifu Yizhou's forces, Yao Xing ambushed and captured him, and then executed him. Qifu Yizhou then withdrew.
