The Chinese dragon, also known as the loong, long or lung ( / 龙), is a legendary creature in Chinese mythology, Chinese folklore, and Chinese culture at large. Chinese dragons have many animal-like forms such as turtles and fish, but are most commonly depicted as snake-like with four legs. Academicians have identified four reliable theories on the origin of the Chinese dragon: snakes, Chinese alligators, thunder worship and nature worship. They traditionally symbolize potent and auspicious powers, particularly control over water. The impression of dragons in a large number of Asian countries has been influenced by Chinese culture, such as in Korea, Vietnam, and Japan. Chinese tradition has always used the dragon totem as the national emblem, and the "Yellow Dragon flag" of the Qing dynasty has influenced the impression that China is a dragon in many European countries. The white dragon of the flag of modern Bhutan is a classic Chinese-style dragon. Historically, the Chinese dragon was associated with the Emperor of China and used as a symbol to represent imperial power. The founder of the Han dynasty Liu Bang claimed that he was conceived after his mother dreamt of a dragon. During the Tang dynasty, Emperors wore robes with dragon motif as an imperial symbol, and high officials might also be presented with dragon robes. In the Yuan dynasty, the two-horned five-clawed dragon was designated for use by the Son of Heaven or Emperor only, while the four-clawed dragon was used by the princes and nobles. Similarly during the Ming and Qing dynasty, the five-clawed dragon was strictly reserved for use by the Emperor only. The dragon in the Qing dynasty appeared on the first Chinese national flag. The image of the Chinese dragon was roughly established in the Shang and Zhou dynasties, but there was no great change for a long time. In the Han Dynasty, the winged Yinglong, as a symbol of feudal imperial power, frequently appeared in Royal Dragon vessels, which means that most of the dragon image designs used by the royal family in the Han Dynasty are Yinglong patterns.
