In the fourth year of Kaiyun, the Khitan invaded the capital, deposed the emperor, and migrated north. The king dispatched General Wang Jun to present a memorial to the Khitan. Yelü Deguang called him his son and bestowed upon him a wooden crutch, which was a custom of the ethnic minorities and was as precious as a walking stick in the Central Plains. Only trusted ministers would be given it.
