《太平广记·卷一百三十五·征应一》
秦始皇的时候，宛渠国的一个老百姓，乘坐着一只能在水底潜行的螺旋形的船来了。他说： 我国距离轩辕黄帝的墓地有十万多里，我国很早以前的圣人就看见冀州有黑风，他就断定冀州应当出现圣人，果然在庆都出现了尧。 
秦始皇时，宛渠国之民，乘螺舟而至，云： 臣国去轩辕之丘十万里，臣国先圣，见冀州有黑风，应出圣人，果庆都生尧。 
During the time of Emperor Qin Shi Huang, a commoner from Wanguo came in a spiral ship that could travel under water. He said, "My country is hundreds of thousands of miles away from the tomb of Xuanyuan Huangdi. A long time ago, the sage of our country saw the dark wind in Jizhou. He determined that a sage would be born in Jizhou. As expected, Yao was born in Qingdu."
