There is an underwater section of the wall in Hebei Province called Xifengkou Wall ("happy meeting"). A legend related that in the Qin Dynasty, a young man was taken away to build the Great Wall. Winter came but he failed to return. His father worried about him so much that he went to the site to look for him. They ran into each other at Songting Hill by chance. They were so happy that they laughed themselves to death. The pass where they were buried was later named Xifeng Kou Pass.
