Yang Guangyuan
In 944, Emperor Taizong launched his attack, with Zhao Yanshou and Zhao Yanzhao () serving as forward commanders. The Liao army quickly reached Tianxiong, upon which Emperor Taizong created Zhao Yanshou the Prince of Wei and commissioned him the military governor of Weibo Circuit (魏博, i.e., Tianxiong). Hearing of the Liao attack, Yang Guangyuan, who had been in secret communications with Liao, openly rebelled against Shi Chonggui at Pinglu Circuit (平盧, headquartered in modern Weifang, Shandong). Liao forces' attempts to cross the Yellow River to aid Yang, however, repeatedly failed, and Emperor Taizong decided to withdraw. Yang's son Yang Chengxun () subsequently arrested his father and surrendered.
