Setting out again with Uisang for Tang China by sea, Wonhyo turned back to Silla, and Uisang went on to Tang alone. The Biographies of Eminent Monks of the Song (988) relates that the two met heavy rain and slept in an earthen hollow by the road, finding in the morning that it was beside an old tomb, and that when they stayed in the tomb the next night, a ghost appeared and tormented them.
