《太平广记·卷九十·异僧四》
有人邀请他的时候，或者去或者不去，也不一定。当时南州有一家姓陈的，衣食丰足，杯渡到了他家，很受欢迎与优待。
时南州有陈家，颇有衣食，渡往其家，甚见迎奉。
When someone invited him, he might go or not, again with no fixed pattern. At that time, there was a Mr. Chen who lived in the southern part of the state and had plenty of food and clothing. Bei Du visited his home and was greatly welcomed and treated with respect.
