The real story: Mulan
Mulan, a 1998 Disney movie, is actually based on a Chinese legend. The Disney story goes like this: Fearful that her ailing father will be drafted into the Chinese military, Mulan takes his spot – though, as a girl living under a patriarchal regime, she is technically unqualified to serve. She cleverly impersonates a man and goes off to train with fellow recruits. Accompanied by her dragon, Mushu, she uses her smarts to help ward off a Hun invasion, falling in love with a dashing captain along the way (source: IMDb).
In ancient inscriptions she is shown to have led numerous military campaigns. The Tu-Fang had fought against the Shang for generations until they were finally defeated by Fu Hao in a single decisive battle. Further campaigns against the neigbouring Yi, Qiang and Ba followed. With up to 13,000 soldiers and important generals Zhi and Hou Gao serving under her, she was the most powerful military leader of her time. This highly unusual status is confirmed by the many weapons, including great battle-axes, unearthed from her tomb.
So the truth is actually much more boring than the Disney version.
An interesting fact is that the Hua Mulan crater on Venus is named after her (source: wikipedia).
