You are probably asking about the stick handle with a flower on both ends? That's called a flower roller.
The history of flower sticks can be traced back to the Song Dynasty. It is a traditional way of exercising and playing games. The flower stick dance is also a sacrificial dance of the Buyi people. It is danced only during the Ha Festival. It is performed by one, two or four Ha girls to drive away wild ghosts and evil spirits when sending off the gods. Later it became an entertaining dance and was also danced on other festivals.
Everyone wears white gowns to dance. During the performance, they hold a wooden stick about a foot long in each hand with colorful paper wrapped around it. They sing first and then dance. The dance is mainly based on the wrist-wrapping stick, with many changes in movements. The faster the accompaniment drum beats, the faster the actors dance, giving people a bold and solemn feeling.
