Near the north gate of the Summer Palace grounds, outside Beijing, I saw an all-women musical group playing this mystery instrument. It has a lovely mellow sound. The double lobed chamber gives on to three flute-like stems with openings which you can finger. I sat and listened for half an hour while The Family went climbing the Longevity Hill. Other audience came and went. Most listened in silence, some clapped at the end of a piece. I waited until The Family came back and joined me. We stayed a while, and then had to leave.
Does someone know the name of this instrument?
