Throughout the rest of Lü Guang's reign, Lü Zuan became the general that his father relied on the most. In 397, when the Xiongnu general Juqu Mengxun rebelled, Lü Guang sent Lü Zuan against him, and Lü Zuan was initially successful in defeating Juqu Mengxun and forcing him to flee. However, after Juqu Mengxun's cousin Juqu Nancheng (沮渠男成) persuaded the official Duan Ye to join them and establish Northern Liang, Lü Guang was faced with a serious rebellion at Guzang itself—a rebellion by the general Yang Gui (楊軌) and the magician Guo Nen (郭黁), and Lü Zuan, while he had Duan Ye's capital Jiankang (建康, in modern Zhangye, Gansu) under siege, was forced to withdraw to fight Yang and Guo, allowing Duan Ye's nascent state to survive. In 398, Lü Zuan and his brother Lü Hong (呂弘) joined forces and defeated Yang and Guo, forcing them to surrender to Southern Liang and Western Qin, respectively.
