铁伐不久被契丹杀死，本国的人又立登注为君主，又被他们的大人阿富提等人杀死，本国的人又立库提为君主。
铁伐寻为契丹所杀，国人复立登注为主，仍为其大人阿富提等所杀，国人复立库提为主。
Not long after, Tiefa was killed by the Qidan people. The Rouran people made Dengzhu the ruler again, but he was killed by Afuti and others who were in influential positions. Then, the Rouran people made Kuti the ruler.
