《太平广记·卷二十七·神仙二十七》
他让属下在此休息，并给属下饭吃。他可怜属下长期受穷，让属下买了二十根铁棒。第二天，属下又遇到他，铁就全都变成金子了。
止吏与食，哀其久贫，命市铁二十梃，明日复与相遇，已化金矣，尽以遗之。
He asked his subordinates to rest and eat here. He pitied his subordinates' long-term poverty and asked them to buy twenty iron rods. The next day, his subordinates met him again, and the iron turned into gold.
