Here is where Da'E comes from:
大鹗 Da'E(a big cormorant)
420 li further northwest is a mountain called Zhongshan. The son of Mount Zhongshan called Gu who has a human face and a dragonís body. Together with Qinpi, he kills Baojiang at a place south of Mount Kunlun. Feeling wrathful, the God of Heaven kills Gu and Qinpi at a cliff east of Mount Zhongshan. As a result, Qinpi turns into Da'E (a big cormorant). He looks like an eagle, but he has black markings, a white head, a red beak and a tigerís paws. He makes a sound like a swan. Wherever it appears, there will be a major war. Gu also turns into a bird called Jun Niao, which looks like a sparrow hawk and has red claws and a strait beak. Singing like a swan, it has yellow markings and a white head. Wherever, there will be a severe drought in that place.
