Zhuangzi, "Enjoyment in Untroubled Ease" quote: "北冥有魚,其名為鯤。鯤之大,不知其幾千里也。" translation: "In the Northern Ocean there is a fish, the name of which is Kun - I do not know how many li in size."
Shiji"Annals of the Five Emperors" quote: "昔帝鴻氏有不才子,掩義隱賊,好行凶慝,天下謂之渾沌。少暤氏有不才子,毀信惡忠,崇飾惡言,天下謂之窮奇。顓頊氏有不才子,不可教訓,不知話言,天下謂之梼杌。此三族世憂之。至于堯,堯未能去。縉云氏有不才子,貪于飲食,冒于貨賄,天下謂之饕餮。天下惡之,比之三凶。舜賓於四門,乃流四凶族,遷于四裔,以御螭魅,於是四門辟,言毋凶人也。"

Shenyijing"Classic of the West Wilderness: Ten Examples" quote: "崑崙西有獸焉,其狀如犬,長毛四足,似羆而無爪,有目而不見,行不開。有兩耳而不聞,有人知往。有腹無五臟,有腸直而不旋,食物徑過。人有德行而往牴觸之。有凶德則往依憑之。天使其然,名為渾沌。《春秋》云:渾沌,帝鴻氏不才子也。空居無為,常咋其尾,回轉仰天而笑。"
