Subsequently, Wang welcomed Li Kuangwei to Chengde Circuit and, out of gratitude, honored him like a father (as Wang was himself only 19 years old), but Li Kuangwei then tried to seize the circuit from Wang, and was killed by soldiers loyal to Wang. Hearing of Li Kuangwei's death, Li Kuangchou submitted a petition to then-reigning Emperor Zhaozong, requesting permission to attack Chengde to avenge Li Kuangwei; Emperor Zhaozong refused to grant such permission. Meanwhile, the officer Liu Rengong, whose soldiers had long been stationed at Wei Prefecture (蔚州, in modern Zhangjiakou, Hebei) and who had wanted to return to You Prefecture (幽州, i.e., Fanyang), led his soldiers to attack Li Kuangchou. Li Kuangchou's army, however, defeated Liu's at Juyong Pass, and Liu fled to Li Keyong's Hedong Circuit. Later in the year, even without Emperor Zhaozong's authorization, Li Kuangchou attacked Chengde cities Leshou (樂壽, in modern Cangzhou, Hebei) and Wuqiang (武強, in modern Hengshui, Hebei), ostensibly to avenge Li Kuangwei. In spring 894, Emperor Zhaozong officially commissioned him as military governor.
