The literal translation of the title of this movie is: Flying to the Moon.
This movie is made for entertainment purposes only, and contrary to what is claimed in the plot summary, this movie is not based on the traditional folklore, but rather, some series of Hong Kong cartoons that is based on martial arts novels.
The only thing that remotely links the this movie and the popular traditional folklore is that the original martial arts novels did included the folklore, but that is it. For example, the emperor was the seventh emperor of Han Dynasty, around 150 B.C, but the protagonists in folklore actually lived in Xia dynasty, around 2100 B.C.
