北凉
In summer 400, when Lü Zuan made a major attack on Northern Liang, Tufa Rutan, probably at Tufa Lilugu's instruction, made a surprise attack on the Later Liang capital Guzang (姑臧, in modern Wuwei, Gansu), entering Guzang's eastern half and then retreating after successfully pillaging the city, forcing Lü Zuan to abandon his Northern Liang campaign.
