Yang Guangyuan
In 944, during a time that there were major military confrontations between Later Jin and its northern rival, the Khitan Liao Dynasty, which was at that time aiding Yang Guangyuan, a Later Jin general who had rebelled at Pinglu Circuit (平盧, headquartered in modern Weifang, Shandong), Li Yiyin submitted a report to Shi indicating that he had taken his 40,000 men and made an incursion into Liao territory, across the Yellow River, from his Lin Prefecture (麟州, in modern Yulin). Shi gave him the title of the commander of southwestern forces against the Khitan.
