姚苌
After the Battle of Feishui, the power of the Former Qin quickly unraveled as various regimes in the North broke loose. In 384, Murong Chui founded the Later Yan in Hebei. Other Murong royals founded the Western Yan in Shanxi. Yao Chang founded the Later Qin in eastern Gansu. Fu Jian was killed by Yao Chang, but the Former Qin survived by relocating from Shaanxi to Gansu and then Qinghai. In 385, Qifu Guoren, a Xianbei former vassal under Fu Jian, founded the Western Qin. In 386, Lü Guang, a Di general of the Former Qin, founded the Later Liang in western Gansu. Tuoba Gui revived the Dai as the Northern Wei. In 388, Zhai Liao, an ethnic Dingling leader in Henan founded the Zhai Wei, which was wedged between the Later Yan, Western Yan and Eastern Jin. As many as seven kingdoms coexisted for nine years.
