This would mark the apex of Li Keyong's status as far as the Tang imperial government was concerned, however. As Li Keyong was waging his campaign in the west, Zhu Quanzhong was repeatedly defeating Zhu Xuan and Zhu Jing, and Li Keyong made repeated attempts to aid Zhu Xuan and Zhu Jing. In late 895, he sent Shi Yan and Li Chengsi (李承嗣), through Weibo territory, to rendezvous with Zhu Xuan and Zhu Jing. In spring 896, he again tried to send Li Cunxin to aid Zhu Xuan and Zhu Jing, but Zhu Quanzhong warned Weibo's military governor Luo Hongxin that Li Keyong had designs on the entire region north of Yellow River, including Weibo. Further, Li Cunxin's army had poor discipline and was pillaging the Weibo people as it went through Weibo, angering Luo. Luo thus launched a surprise attack at night against Li Cunxin, defeating him and forcing him to withdraw to Ming Prefecture. Thereafter, Luo no longer permitted Hedong forces passage through Weibo, causing Shi and Li Chengsi to be stuck at Tianping and no longer able to return to Hedong, and Luo thereafter became an ally of Zhu Quanzhong's.
