query: What do dragons represent in Chinese mythology?
passage: Chinese dragon
Historically, the Chinese dragon was associated with the Emperor of China and used a symbol to represent imperial power. The founder of Han dynasty Liu Bang claimed that he was conceived after his mother dreamt of a dragon.[2] During the Tang dynasty, Emperors wore robes with dragon motif as an imperial symbol, and high officials might also be presented with dragon robes.[3] 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.[4] 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.[5]
passage: Chinese dragon
In some circles, it is considered bad luck to depict a dragon facing downwards, as it is seen as disrespectful to place a dragon in such manner that it cannot ascend to the sky. Also, depictions of dragons in tattoos are prevalent as they are symbols of strength and power, especially criminal organisations where dragons hold a meaning all on their own. As such, it is believed that one must be fierce and strong enough, hence earning the right to wear the dragon on his skin, lest his luck be consumed by the dragons.
