Murong Chui
In 386, Tuoba Gui, the descendant of the Dai royal house, who had reestablished Dai earlier that year but subsequently claimed the title Prince of Wei (thus establishing Northern Wei) but faced internal rebellions and turmoil, submitted to Murong Chui as a vassal and sought Former Yan aid. Murong Chui sent Murong Lin to help him, and Northern Wei was preserved.
