And the rover, Yutu(玉兔) is the jade rabbit, who pounds a mortar and pestle in Guanghan Palace on the moon. She later escapes to earth and Chang'e brings her back to the moon in 西遊記 (Journey to the West) right before Sun Wukong (孫悟空; japanese reading: Son Gokū; yes, like in Dragonball, heavily based on 西遊記) defeats her.
