Gungnae City is located in the urban section of Ji' an City, Jilin Province. It was the political, economic and cultural center for the early and middle periods of ancient Kogury regime in Northeast China.
The 19th ruler of Gungnae City was Gwanggaeto of Goguryeo. Goguryeo’s primary task was to secure an independent territory by eliminating the remaining commanders in southern Manchuria and the north-central region of the Korean Peninsula.
