I was curious myself one day, so I did do some quick searching on Google. Qui-Lins are the easiest ones to figure out, as they look like the Chinese equivalent of a unicorn. Typically, they have one antler instead of one horn.
Gao-Xing seems to be Mandarin for "happy", which makes a lot of sense when you see the way those wyrms look: they have a kawaii happy face because of the blind eyes.
Jiao-di gives you results for a wrestling style. I think their plumes and spikes are supposed to imitate the costumes the wrestlers wear. Also, when I did an image search, the drawings of Laochra and Roz from Kiley's signature showed up in the results. XD
And Imperial Fu all look like fu dogs. ^^
