Idy

Idy was a settlement on the western coast of Sakhalin, facing the mainland across the narrow strait. Recorded as Yidui or Yidui Gashan in Qing sources, it belonged to a coast whose inhabitants maintained contacts with the lower Amur. Traders from the mainland crossed to Sakhalin with goods from China and exchanged them for furs and other products. The settlement appeared on the Kangxi-era imperial map of the island.
