Murong Lin
Murong Chui, displeased that Tuoba Gui did not personally come to pay tribute, interrogated Tuoba Yi, but allowed him to depart. Tuoba Yi reported to Tuoba Gui that, in his opinion, Murong Chui was old, his crown prince Murong Bao was weak, and that Murong Chui's brother Murong De the Prince of Fanyang was overly ambitious, which should cause internal problems for Later Yan upon Murong Chui's death. He opined that while Tuoba Gui should not attack Later Yan at that time, once Murong Chui died, there would be opportunity to do so. Despite his planning, however, he continued joint operations with Later Yan, and in 390 and 391, he and Murong Lin defeated the Helan (), Getulin (), and Gexi () tribes together.
