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.
