“In the northern darkness there is a fish and his name is K'un. The K'un is so huge that I don't know how many thousand li it measures. He changes and becomes a bird whose name is P'eng. The p'eng's back measures how many thousand li I don't know, and when it gets up and flies away, its wings are like clouds in the sky. When the sea begins to move, this bird makes its way to the southern darkness, the Lake of Heaven.

When the P'eng travels into the southern darkness, the water is churned for three thousand li. He beats the whirlwind and rises ninety thousand li to embark on the sixth monthly storm." Fluctuating heat, dust particles, living creatures confusing each other - the sky looks very blue. Is this its true color or is it because it is so far away and has no end? When the bird looks down, everything it sees is also blue.
