The Chinese look to the dragons as protectors and controllers of the habitat . They had different dragons for different purposes in life. If a mortal upset a dragon, then it would be one of the worst floods known to man, and volcanoes would erupt when the fucanglong dragon reported to heaven.
I personally find this very interesting that the Chinese put their beliefs in a mythical creature. I don't think I would have fallen for all of that crap, but every one's entitled to their opinion. I thought it was really cool how there were so many different kinds of dragons, and they all had there own purpose in life.
This tells me they believed strongly in what their religion told them, and they feared dragons for good reason. Maybe the whole dragon theory kept them in line to not mess up or slack off because they feared the dragon so strongly
