title: Chinese dragon
context: 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]
