Based on the life of Yue Fei, a Chinese military general who lived during the Southern Song dynasty and considered a national hero of China.

This movie is based on the famous Chinese folklore that is more than one and a half millennium old. The same folklore was what the Disney animation Mulan is based on, and similarly, it was what many Chinese movies/operas/plays based on.

The story was liberally adapted from a short sequence in the popular Chinese folk tale Journey to the West. Princess Iron Fan is a main character. Specifically, the film focused on the duel between the Monkey King and a vengeful princess, whose fan is desperately needed to quench the flames that surround a peasant village.
