《辽史·本纪·卷三十》
以青牛白马祭天，树立旗帜向众人立誓说： 我大辽自从太祖、太宗艰难地创立大业，后来即位之君王沉溺于享乐，毫无节制，不顾念国家政事，以致盗贼纷起，天下土崩瓦解。
以青牛白马祭天，树旗以誓于众曰： 我大辽自太祖、太宗艰难而成帝业，其后嗣君耽乐无厌，不恤国政，盗贼蜂起，天下土崩。
They sacrificed a blue bull and a white horse to Heaven, and planted a flag, whereupon they swore an oath to the assembled people: My Great Liao has experienced the difficulties of establishing the great cause by our ancestors Taizu and Taizong, but later the rulers who succeeded to the throne indulged in pleasures and gave free rein to their desires, taking no account of state affairs, with the result that bandits rose up everywhere and the country fell apart.
