《太平广记·卷八十五·异人五》
恰好有个豫章府的差役，姓杨，是彦伯过去就认识的老乡，也在这家客店住宿。他便教给彦伯说： 凡属行旅之人到了这里，没有不祭祀古帝金天氏的，祭奠之后必能得到一个梦，暗示给你吉凶福祸；即使没有梦，这家客店的老板娘也能知道未来的事，如能从她那里得到一句话，也可以。 
会豫章邸吏姓杨，乡里旧知，同宿于是，因教己云： 凡行旅至此，未尝不祷金天，必获梦寐之报。纵无梦，则此店之妪亦能知方来事，苟获一言，亦可矣。 
It just so happened that an official of Yuzhang Prefecture, who had the same surname of Yan as Yanbo, and was a fellow townsman whom he knew, also stayed at that guest house. He instructed Yanbo, saying: "Anyone traveling here will definitely sacrifice to the ancient Emperor Jīn Tiānshì (Golden Heavenly Emperor). After the sacrifice, you will surely have a dream, which will show you good or bad fortune. Even if you do not have a dream, the proprietress of this guest house can also tell the future. If you can get a word from her, that will be good too."
