These are administrative agencies in Korea. Chungju City Hall, Daegu Metropolitan City Hall, and Cheongdo-gun Office in order from the left. Electricity, water, and roads are all unnecessary, and the night view is included. Metropolitan City Hall handles administrative affairs of the metropolitan city, City Hall handles administrative affairs of the city, and County Office handles administrative affairs of the county. It is part of the Korean administrative system. I hope you use it well. Thank you.
