Wuliehe

Wuliehe was a post in the basin of the Tym on Sakhalin, where the island's rivers and forests met networks extending across the strait to the Amur. Under the Yuan, Ainu elders brought tribute to Wuliehe and received gifts in return, making the post a place of exchange as well as political contact. The Ming later maintained relations with Sakhalin leaders; in 1431 an official associated with Wuliehe presented marten pelts as tribute.
