From the Classic of Mountains and Seas: North Mountain Chapter:
Two hundred li to the north lies Fajiu Mountain, upon which grow many withered trees. There lives a bird, its form like a crow, with a patterned head, a white beak, and red feet. Its name is Jingwei, and its call sounds like its name. She was the youngest daughter of the Flame Emperor, named Nuwa. Nuwa was swimming in the East Sea when she drowned and never returned. Thus, she transformed into the Jingwei bird, which constantly carries twigs and stones from the West Mountain in its beak to fill up the East Sea.
Nuwa, who drowned in the East Sea, transformed into the little bird Jingwei, endlessly carrying twigs and stones in an attempt to fill the sea and avenge herself.
When Shen Feng first read this story, he was initially moved by its tragic grandeur. But then, he was shaken by the intense desire for revenge, so much so that the hairs on his arms stood on end.
