The Song of mulan is a famous ballad about a heroine of the Northern Dynasties. In this ballad, this heroine is called Mulan. But people always call her Hua Mulan. And in 1998 Hollywood made an animated cartoon Hua Mulan. But this cartoon is a light program, so it can’t tampil a real Mulan. I have seen a movie Joan of Arc which directed oleh Luc Besson, and this movie hurted seriously the image of a herine that I have known about Joan of Arc since my childhood. So if we want to know about historical persons, we must research true historical materials.
