The Birth of a K'iu-Lung
After a lung has reached the age of five hundred years old it transforms into a k'iu-lung.  A K'iu-lung can also be born from a sea plant called hai-lu. 
The K'iu-Lung are Blue Chinese dragons  with horns.  Even without wings, they fly upward into the sky.  After a K'iu-Lung lives to be one thousand years, it transforms into a Ying-Lung. 
K'iu-Lung inhabit pools with gavial and fish, and if one is drained off, the k'iu-lung and its blessings with disappear.
