He is a legendary figure who observed the sky and investigated everything on the earth to produce for the first time the book of text "Niaojishu" that shocked people with the world unseen. Thus people called him the ancestor of humanities, and Yellow Emperor bestowed on him a surname "Cang" , which literally means firmament.
