Ah! awesome. I understood this stuff _very briefly_ as a
  teenager (just learning my signs and such) - but didn't REALLY
  start to grasp it 'til I was playing Pokemon with my nephew and
  also his involvement with the Avatar:the last airbender series.
  It was at that point I had to get over resisting elementals
  knowledge that I was avoiding for a long time. I don't know why
  I was avoiding it but I was. Anyway, because the interactions of
  the elementals in children's fiction is *based upon* actual
  Chinese elementals moreso than English Medieval elementals, I
  suspect what they showed him in his game and shows is likely
  accurate enough to the gist of Chinese astrology. Anyway, cool
  smile emoticon I learned something today. [I wasn't making a
  comparison btw - just showing the tremendous influence
  elementals knowledge has had upon culture in surprising ways]
