By spring 897, Zhu Quanzhong had achieved final victory against two military governors that he had waged war for years — Zhu Xuan the military governor of Tianping Circuit (天平, headquartered in modern Tai'an, Shandong) and Zhu Xuan's cousin Zhu Jin the military governor of Taining Circuit (泰寧, headquartered in modern Jining, Shandong) — capturing and executing Zhu Xuan, forcing Zhu Jin to flee, and taking control of both circuits, allowing him full control of the region between the Yellow River and the Huai River. (Shi Pu's Ganhua Circuit had fallen to him in 893.) Zhu Jin fled to Huainan, along with the Hedong Circuit (河東, headquartered in modern Taiyuan, Shanxi) officers Shi Yan () and Li Chengsi (), whom Hedong's military governor Li Keyong had previously sent to aid Zhu Xuan and Zhu Jin. Yang personally went to Gaoyou (高郵, in modern Yangzhou) to welcome them. It was said that previously, the Huainan forces were only capable at water welfare, and now with the injection of the field soldiers from Tianping, Taining, and Hedong, their field fighting capabilities were greatly improved. Li Keyong subsequently sent emissaries to Yang, requesting that Shi and Li Chengsi be returned to him; Yang agreed, but as Yang treated Shi and Li Chengsi well and awarded them with much treasure, neither Shi nor Li Chengsi actually ever returned to Hedong, and they served Huainan thereafter.
