When did the little leopard Sheng start wearing grass skirts?

There is no exact time. Bao Xiaozi's voice, also known as Bao Xiaozi's dance, is a primitive folk dance circulating in Zu E Village, Damaidi Town, Shuangbai County, Yunnan Province, China. Every year, the Yi people in Zu E Village dance Bao Xiaozi Sheng on the Torch Festival on June 24th and the Ghost Festival on July15th. Because it has been circulating for a long time, it is impossible to trace back the time when Bao Xiaozisheng began to wear grass skirts, and there is no accurate time.
