There is the (book called) Qi Xie, a record of marvels. We have in it these words: ‘When the phang is removing to the Southern Ocean it flaps (its wings) on the water for 3000 li. Then it ascends on a whirlwind 90,000 li, and it rests only at the end of six months.’ (But similar to this is the movement of the breezes which we call) the horses of the fields, of the dust (which quivers in the sunbeams), and of living things as they are blown against one another by the air. Is its azure the proper colour of the sky? Or is it occasioned by its distance and illimitable extent? If one were looking down (from above), the very same appearance would just meet his view.
