Early medieval history From 698 to 936, the kingdom of
Balhae occupied northern
Korea and parts of
Manchuria and
Primorsky Krai, consisting of the
Nanai, the
Udege, and descendants of the
Tungus-speaking people and the people of the recently fallen
Goguryeo kingdom of Korea. It bordered the Khitan people, the Shiwei people, the Silla people, and the citizens of Heisui Mohe, most of which is located in modern-day China and Mongolia. The vicinity of Tongjiang was settled at this moment by Funie
Mohe tribes (
Hanja/
Hanzi: ; ; ). These tribes were submitted to Balhae Kingdom under King
Mun's reign (737-793). Later, King
Seon (r.818-830), administered their territories by creating a prefecture in the neighbourhood: The Dongpyong Prefecture () with Yiju (), present-day Dangbi () as its administrative centre. == Administrative divisions ==
