As Dragons were said to represent the Four Elements, so the stories and myths of dragons who had dominion over Air, Water, Earth and Fire. Each of these elemental dragons had unique characteristics that had to be taken into consideration. To the Chinese, the fire-spitting dragon was principally associated with lightning, and by extension to thunder and rainmaking, which made it a symbol of fertility. All this celestial activity was how Earth and Water elements were united. Water dragons were thought to protect and act as guardians of streams, lakes, rivers and even individual pools. It was thought that dragons were able to make springs bubble from the ground.
