Hua Mulan is the eldest daughter in the family. She has a cheerful and straightforward personality. Her parents tried their best to help their daughter find a good home, but their efforts failed many times. At this time, they received news of the invasion of the Huns in the north, and the court summoned strong men from all households. Mulan's father was also on the list. Mulan couldn't bear to see her elderly and disabled father fighting on the battlefield, so she decided to cut her long hair, steal her father's armor, and decided to dress up as a man to join the army in his place. In order to protect Mulan, the ancestors of the Hua family sent the kind-hearted Mushu to help. In the process of joining the army, Mulan passed the difficult training one after another with her strong will, and her spirit also moved all her comrades. Just when the battle situation was critical, her identity as a woman was also discovered. She was left in the snow, and in the end it was her timely appearance that successfully assisted the army in repelling the Huns.
