In the northern darkness there is a fish and his name is K'un. The K'un is so huge I don't know how many thousand li he measures. He changes and becomes a bird whose name is P'eng. The back of the P'eng measures I don't know how many thousand li across and, when he rises up and flies off, his wings are like clouds all over the sky. When the sea begins to move, this bird sets off for the southern darkness, which is the Lake of Heaven.

The Universal Harmony records various wonders, and it says: "When the P'eng journeys to the southern darkness, the waters are roiled for three thousand li. He beats the whirlwind and rises ninety thousand li, setting off on the sixth month gale." Wavering heat, bits of dust, living things blowing each other about – the sky looks very blue. Is that its real color, or is it because it is so far away and has no end? When the bird looks down, all he sees is blue too.
