Introduction to the cultural relics of Erlang God: The legend of "Erlang God" has been circulated in Guannan County for a long time, especially the story of "Erlang Guanhe killed Jiao to make his hometown" which connects Guannan more closely with the Journey to the West culture. According to records in many literary works and expert research, the Guanjiang estuary where Erlang Shen was stationed is the current Guanhe estuary in Guannan. In order to promote the Journey to the West culture and explore local cultural heritage, the Erlangshen Cultural Relics Park started construction on May 20, 2010, forming the "Great Journey to the West Cultural Tourism Circle" from Lianyungang to Guannan to Huai'an.
