Why the Chinese dragon has the head of a camel?

Historically, the dragon was the symbol of the Emperor of China. In the Zhou Dynasty, the 5-clawed dragon was assigned to the Son of Heaven, the 4-clawed dragon to the Zhuhou (seigneur), and the 3-clawed dragon to the Daifu. In the Qin Dynasty, the 5-clawed dragon was assigned to represent the Emperor while the 4-clawed and 3-clawed dragons were assigned to the commoners. The dragon in the Qin Dynasty appeared on national flags.[1]

The dragon is sometimes used in the West as a national emblem of China. However, this usage within both the People's Republic of Chinaand the Republic of China on Taiwan as the symbol of nation is not common. Instead, it is generally used as the symbol of culture. In Hong Kong, the dragon is part of the design of Brand Hong Kong, a symbol used to promote Hong Kong as an international brand name.[2]
