杨光远
In spring 936, in order to test Li Congke's intentions toward him, Shi requested to be transferred. Believing that Shi would rebel if he transferred Shi but that he could defeat the rebellion, Li Congke issued an edict transferring Shi to Tianping Circuit (天平, headquartered in modern Tai'an, Shandong) and a close associate, Song Shenqian () the military governor of Heyang Circuit (河陽, headquartered in modern Jiaozuo, Henan) to Hedong. He also ordered Zhang to go to Hedong to "escort" Shi from Hedong to Tianping, to put pressure on Shi. Shi thereafter rebelled, issuing a declaration claiming that as Li Congke was an adoptive son, he should not be emperor, and that he should pass the throne to a younger brother, Li Congyi the Prince of Xu (Li Siyuan's youngest biological son). Li Congke, in response, put Zhang in command of an army to attack Hedong, with Yang Guangyuan the military governor of Yiwu Circuit (義武, headquartered in modern Baoding, Hebei) serving as his deputy.
