The dragon dance is performed by a skilled team whose job is to bring the motionless body to life. The correct combination and proper timing of the different parts of the dragon are very important to make a successful dance. Any mistakes made by even some of the performers would spoil the whole performance. To be very successful in the dance, the head of the Dragon must be able to coordinate with the body movement to match the timing of the drum. For larger ceremonial and parade style dragons, the head can weigh as much as 12 katis (14.4 kg, almost 32 lb). The dragon tail also has an important role to play as it will have to keep in time with head movements. The fifth section is considered to be the middle portion and the performers must be very alert as the body movements change from time to time. The dragon is often led by a person holding a spherical object representing a pearl.
