Jiang Xinghuo then outlined the coastline of Japan, pointing to a small island in the north and said.

"Sado Jinshan is an isolated island hanging overseas. It has been the exile place of Japan all the time. Its status is like Lingnan in Tang and Song Dynasties."

Jiang Xinghuo pointed to another part of the coastline and said, "Iwami Ginzan is located in the 'China' region in the traditional sense of Japan. It is not far from the long northern part of the coast, and there is no need to go deep into the land."
