Chakchegŏn

He became rich and influential via the Yellow Sea maritime trade, extending his influence beyond Songak to Chongju, Yonan, Paechon, and Ganghwa.

In Min Chi's Pyeonnyeon Gangmok (편년강목; 編年綱目), he claimed that earlier Goryeo historians such as Kim had confused Xuanzong with Suzong, due to the latter's posthumous name.

Joseon historians dismissed the idea of a Tang emperor being Chakchegon's father as Seon Buddhist myths and legends.

There he met the Dragon King of the Western Sea who asked Chakchegon to get rid of his nemesis, Old Mr. Fox.
