The word “dragon” has also come to be applied to the Chinese lung, which are associated with good fortune and are thought to have power over rain. Dragons and their associations with rain are the source of the Chinese customs of dragon dancing and dragon boat racing. Many East Asian deities and demigods have dragons as their personal mounts or companions. Dragons were also identified with the Emperor of China, who, during later Chinese imperial history, was the only one permitted to have dragons on his house, clothing, or personal articles.
Commonalities between dragons’ traits are often a hybridization of avian, feline, and reptilian features, and may include: snakelike features, reptilian scaly skin, four legs with three or four toes on each, spinal nodes running down the back, a tail, and a serrated jaw with rows of teeth. Several modern scholars believe huge extinct or migrating crocodiles bear the closest resemblance, especially when encountered in forested or swampy areas, and are most likely the template of modern dragon imagery.
