Chinese dragons are associated with water, not fire:
Initially, the dragon was benevolent but the Buddhists introduced the concept of malevolent influence among some dragons. Just as water destroys, they said, so can some dragons destroy via floods, tidal waves and storms. They suggested that some of the worst floods were believed to have been the result of a mortal upsetting a dragon.
Chinese dragons are occasionally depicted with bat-like wings growing out of the front limbs, but most do not have wings, as their ability to fly (and control rain/water, etc.) are mystical and not seen as a result of their physical attributes.
