The king of Kongmin of Goryo dynasty dispatched diplomacy to Japan in the year of 1366 to request the prevent of Waegoo(Japanese piretes). In response to this, Muromachi Bakuhu ordered Syouni yorihisa(the shugo of tsushima island) and So tsuneshige(the shugodai of the island), to prevent the Waegoo. Therefore So tsuneshige dispatched the diplomacy to Goryo in July 1368, and concluded a peace treaty with Goryo government. But the next month, Yuan dynasty escaped from Peijing and the army of Ming enter the Peijing castle. 18th July of the year of 1368, Goryo government heard the news of flee of Yuan dynasty and the diplomacy of So tsuneshige who had come to Goryo also knew that news.
