In 403, with his Later Liang state continuously under attack by Northern Liang and Southern Liang, Lü Long surrendered the Guzang region—the only territory still remaining under Later Liang control—to Later Qin, thus ending Later Liang. Yao Xing moved Lü Long and his clan to Chang'an and made him and his brother Lü Chao (呂超) officials. However, because Northern Liang and Southern Liang were only nominal vassals, Guzang was effectively a lone island of Later Qin control. In 404, Southern Liang's king Tufa Rutan (Tufa Lilugu's brother) stopped claiming kingly title and using his own era name, in a further showing of submission to Later Qin, although internally he remained effectively independent.
