Meanwhile, with the original Later Jin-commissioned military governors no longer at their circuits, many circuits began to raise in rebellion against Liao, starting with Baoyi Circuit (保義, headquartered in modern Sanmenxia, Henan), whose officers assassinated the Liao-commissioned deputy military governor Liu Yuan (劉願) and supported one of their own, Zhao Hui (趙暉), in rebellion against Liao. Not long after, Liu Zhiyuan declared himself emperor at Hedong (initially without a new name for his state, but later known as Later Han. After Liu's declaration of himself as emperor, many of the circuits resisting Liao pledged allegiance to him. This included many agrarian rebels, causing Emperor Taizong to lament, "I did not know that the Chinese people are this difficult to rule." He sent some of the military governors back to their circuits with Liao soldiers escorting them, but was unable to stem these rebellions.
