In Disney's Mulan, the final battle takes place in the Imperial City.
After the Huns invade China, Mulan and the Chinese army travel to the capital, where Shan Yu and his forces attack the emperor. The climactic confrontation unfolds around the palace and its rooftops, with Mulan using her intelligence and military experience to help defeat the invaders and rescue the emperor.
The film calls the location the Imperial City, reflecting the imperial capital setting without presenting it as a strict historical reconstruction. Mulan is inspired by the Chinese legend of Hua Mulan, but Disney's characters, songs, comedy, and action are fictionalized. The location is sometimes confused with the Forbidden City, the real palace complex in Beijing; that name is not the film's stated answer.
