Dated 986, it is written in the Mongolic Khitan language using the Khitan large script. With 19 lines and 271 characters it was found in 1964 at Baimu Mountain, Chaoyang County, Liaoning, China. and is now kept in the Liaoning Province Museum, China.
The Khitan word 'jau' (hundred) which occurs in line 13 of the upper-right Khitan section of the inscription and which is written with the large script character 百 is one of the earliest fully deciphered Mongolic words preserved in a Mongolic inscription.
Yelü Yanning is not mentioned in the Liaoshi or other Khitan historical documents. The discovery of his memorial inscription in 1964 gave the first information about him. Yelü Yanning (946-985) was a high ranking Khitan military officer of the Liao dynasty. Yelü Yanning’s family belonged to the imperial household and had a place in the horizontal gers of the Khitan Khan. His great-grandfather Gaoligu, grandfather Zhiwubu and his father Sage were all widely known as brave and expert warriors who repeatedly accomplished meritorious deeds. His father Sage was given the title "Imperial Tutor Honorable Duke". When the Jingzong Emperor Yelü Xian succeeded to the throne Yelü Yanning was recruited as a jinshi (close supporter). Yelü Yanning was gradually given various titles such as "State-defending Righteous Outstanding Minister", "Sublime Fortunate Minister", "High Inspector", "Imperial Censor", "State High Support" and "Great General".
