Here are a few links to other pages
that have brief descriptions on the Chinese Lion Dance.
As you go through many of these explanations, you'll find
a general theme as well as descrpancies in the Lion Folklore.
I can offer this insite, the lion is not an indigenous creature
to China and thus, there are going to be many version of
how it came to be in China. None of them are wrong persay,
it's just personal interpretations.

There are other links and what not,
but I am not entirely fond of the web set up. (geek stuff)
As I get a better idea what point I want to take, I'll update
this page accordingly.
