《太平广记·卷七十一·道术一》
又有一次，葛玄去游会稽，有个商人从中原来时路过一座神庙，庙神使主簿叫他告诉商人说： 想要顺便捎去一封信给葛公，你可以替我送给他。 
又玄游会稽，有贾人从中国过神庙，庙神使主簿教语贾人曰： 欲附一封书与葛公，可为致之。 
On another occasion, Ge Xuan went to visit Kuaiji. A businessman from Central China happened to pass by a temple. The temple god asked the registrar to tell the businessman: “If you’re willing to take a letter as a favor to Ge Gong, you can deliver it to him for me.”
