Donghwa-dong is an administrative dong located in the eastern part of Jung-gu. It shares its eastern border with Seongdong-gu and is connected to Ahyeok-dong to the south within the same district. To the west, it borders Sindong-dong, and to the north, it is adjacent to Sindong 5-dong. Originally, the administrative dongs in this area were designated with numerical names from Sindong 1-dong to Sindong 6-dong, assigned by the government in a mechanical manner. Subsequently, a resident survey was conducted to select new names from publicly solicited candidates. Consequently, on July 20, 2013, all dongs, except Sindong 5-dong, underwent a simultaneous name change, with Sindong 6-dong being renamed as "Donghwa-dong."
