北涼
Around the new year 402, in response to a request for assistance from the Later Liang rebel Jiao Lang (焦朗), Tufa Lilugu sent Tufa Rutan to assist Jiao, and Tufa Rutan and Jiao then attacked Guzang, dealing Later Liang a major defeat. Oddly enough, however, when Northern Liang attacked Later Liang in spring 402, Tufa Lilugu sent Tufa Rutan to aid Later Liang, although by the time Tufa Rutan arrived, Northern Liang had already retreated.
