Li Keyong
Li Keyong also resumed his campaign against Helian in summer 891, putting Yun Prefecture under siege. By fall 891, Helian had run out of food supplies, and he fled to Li Kuangwei's Lulong Circuit. Li Keyong took over Datong Circuit and made his officer Shi Shanyou (石善友) the defender of Datong. Meanwhile, at the suggestion of Li Cunxiao (who had now been made the military governor of Xingming Circuit—i.e., Meng Fangli's old territory), Li Keyong also launched an attack on Wang Rong's Chengde Circuit in fall 891, but after Li Kuangwei launched troops to aid Wang, Li Keyong withdrew back to Ming Prefecture. Wang and Li Kuangwei subsequently counterattacked in spring 892, but Li Keyong repelled them. Li Keyong and Wang Chucun subsequently attacked Chengde with indecisive results. He withdrew, and later in the year repelled an effort by Li Kuangwei and Helian to recapture Datong.
