 The relationship between the Liao and the Later Jin soured after the death of Shi Jingtang in 942 and the elevation to the throne of Shi Chonggui , also known as Emperor Chudi of Later Jin . The new emperor surrounded himself with anti @-@ Khitan advisers , and in 943 he expelled the Liao envoy from the Jin capital of Kaifeng and seized the property owned by Khitan merchants in the city . By the end of the following year Emperor Taizong had launched an invasion of the Jin . Although the invasion took three years and the Liao faced several setbacks , by the end of 946 Emperor Taizong had secured the surrender of the head of the Later Jin forces and was able to march into Kaifeng unopposed . Emperor Taizong celebrated his victory with the adoption of the dynastic name " Greater Liao " . The invading Liao forces , who had not brought adequate supplies for their invasion , began looting the newly conquered territory and imposed high taxes on the ethnic Chinese population in the formerly Jin lands . This sparked a series of rebellions that culminated in 947 with the establishment of the Later Han by the former Jin governor Liu Zhiyuan . After occupying Kaifeng for only three months , Emperor Taizong and the Liao were forced to retreat north . During the retreat Emperor Taizong died of a sudden illness , just south of modern @-@ day Shijiazhuang , Hebei .
