- Development
Sheng originally consists of several bamboo pipes bound together with ropes or wooden frames. To make Sheng distinguishable from Paixiao, designers added bamboo reeds and a cup-shaped Dou to it. The cup-shaped Dou is made of calabash, and the blowtorch is made of wood. A dozen bamboo pipes are arranged on top of the Dou. After the Tang Dynasty, performers began to make wooden Dou. Later, Dou and the reed were made of copper.
