The duxianqin is a Chinese plucked string instrument with only one string; it is derived from the Vietnamese đàn bầu. Chinese sources describe duxianqin as being an instrument of the Jing (also spelled Gin or Kinh) ethnic group, who are ethnic Vietnamese living in China. It is still commonly played by this ethnic group. Sometimes the body of the instrument is made from a large tube of bamboo rather than wood, which is more common in Vietnam.
