Little yellow teacup

Saw this for sale at my favorite Chinese restaurant and could not resist it.  The dragon has a red ball with lines coming out from it, apparently this symbolizes a flaming pearl which represents good luck and wealth.  The dragon in Tibetan lore is called Druk; Trungpa Rinpoche is known to his students, for example, as the Druk Sakyong or Dragon Earth Protector.  The dragon in Chinese lore is a symbol of imperial authority, as well as the ruler of water and weather.

Below is a closeup of said red ball.
