On Fajiu Hill grew a lot of mulberry trees.Among them lived a bird which looked like a crow,but had a colourful head,a white bill and two red claws.Its call sounded like its name:Jingwei.The bird was said to be Emperor Yandi's youngest daughter,Nü Wá,who,while playing on the East Sea,had been drowned and never returned.She had turned into Jingwei,and the bird would often carry bits of twigs and stones all the way from the west mountains to the East Sea to fill it up.
