1368, the Yuan Dynasty perished and lost control of Mobei. In the early years of Hongwu in Ming Taizu, most tribal leaders in Nuergan area of Heilongjiang Province who belonged to Yuan Dynasty surrendered to Ming Dynasty. The Ming Dynasty forces gradually entered Sakhalin Island.
1409, the Ming Dynasty set up a headquarters in Nuergancheng, the old place of the Yuan Dynasty (before that, the Ming Dynasty had set up a 1 15 health clinic in the Heilongjiang River basin). In the same year, the Ming army conquered Wu and Sakhalin Island entered the territory of the Ming Dynasty. Since then, the local residents on the island have sent a formal tribute delegation to the Ming government.
14 12 years, the Ming dynasty awarded titles to local residents, and set up South Havel in the northern coastal area of Sakhalin Island, Boluo Hewei in the central Bolonai River basin, and Wulie Hewei in the eastern Bolonai River basin. Each Wei dynasty governs the local military and political affairs and is subordinate to Nurgandus.
