The Ruler of the Southern Ocean was Shû (Heedless), the Ruler of
the Northern Ocean was Hû (Sudden), and the Ruler of the Centre
was Chaos. Shû and Hû were continually meeting in the land of
Chaos, who treated them very well. They consulted together how
they might repay his kindness, and said, "Men all have seven
orifices for the purpose of seeing, hearing, eating, and
breathing, while this poor Ruler alone has not one. Let us try
and make them for him." Accordingly they dug one orifice in him
every day; and at the end of seven days Chaos died.—[Chuang
