Du Chongwei
Shi Jingtang died in 942. His nephew and successor, Shi Chonggui, came under the influence of an anti-Khitan court led by the army commander Jing Yanguang. In 943, Shi Chonggui revoked the trading privileges of the Khitans in Kaifeng and confiscated their property, sending their representative back to the Khitan court. Taizong invaded in the following year but suffered a defeat in 945, having to escape the battle on a camel. However with persistence, the Khitans wore down the Jin forces, and in 946, the Jin commander in chief, Du Chongwei, surrendered. In early 947, Taizong entered Kaifeng unopposed. The Jin emperor and his family were exiled to the Supreme Capital. The Jin army was disarmed and disbanded, their horses confiscated. With this great victory, Taizong formally adopted a dynastic name, the "Great Liao". With the conquest of Later Jin, the Liao acquired the Jade Seal of State Transmission (chuanguo yuxi). Ideologically, the Liao therefore regarded itself as the legitimate successor of the Later Jin, and the ruler of China. It hence chose the Water element, the element that follows the Metal element, the dynastic element of the Later Jin, according to the sequence of creation of the Five Elements (wuxing). It also chose the Water element's corresponding color black as its dynastic color.
