What are the characteristics of the Japanese Okinawa classical dance Laoyong?

The "old man forever" in the classical dance in Okinawa, Japan, is called "Weng" in Japanese local arts. It means to pray for national stability, people's unity, population prosperity and bumper crops. In the local wild talk, the performance begins with a dance to greet the gods, and then the official performance begins. That's what the old people in Okinawa mean.
