I have seen the Dragon Dance being performed many times before, but it is my first time to see a circle being chased by the dragon. Perhaps I was simply not paying too much attention before. Anyway, the circle I am referring to is called the Pearl of Wisdom. The chase symbolizes how the dragon pursues knowledge.
During a dragon dance, the people operating the dragon move in an up and down motion that jives with the gongs and drums. There is also the Lion Dance which is often misnamed during parades because the Dragon Dance is always on the spotlight.
The parade of course would not be complete without firecrackers! Kung Hei Fat Choi!
