Mulan was a young girl in ancient China who disguised herself as a man to take her father's place in the army when he was called to fight, despite girls not being allowed to serve. She fought bravely for many years without revealing her true identity. When the war ended, Mulan was called before the emperor and offered a reward, but asked only for a horse to return to her family. Upon returning home, Mulan transformed back into her identity as a woman. Her courageous actions inspired many others.
