|The zhuihu (坠胡, pinyin: zhùihú; also called zhuiqin or
zhuizixian) is a two-stringed bowed string instrument from China. In construction,
it resembles the sanxian, and likely evolved as a bowed version of that
instrument. Unlike bowed string instruments in the huqin family (such
as the erhu), the zhuihu has a fretless fingerboard against which the
strings are pressed while playing.
The zhuihu is used to accompany a form of traditional narrative singing called zhuizi which originated in the Henan province of China.
A more modern version of the zhuihu called leiqin was developed in China in the 20th century. Another related instrument is the Japanese kokyu.

Zhuihu (Bowed String Instrument), also known as Zhuiqin or Zhuizi, is altered from Sanxian (a three-stringed musical instrument), can be used to perform solo and tutti. Since Zhuihu has a wide diapason, a soft sound and relatively high sound volume, performers can use it to imitate the voice of human and animals.
There is one legend about the origin of Zhuihu. In the Qing Dynasty (1644-1911), Emperor Kangxi forbad all the opera performances in the Forbidden City and artists had to earn a living on the street. One day, an artist's Sanxian was bitten by mice and the covering leather of the sound box got a hole in it. In order not to miss the performance, the artist had to use a thin wooden piece to replace the leather and used a bow from Huqin (two-stringed Chinese violin) to play the Sanxian. This musical instrument, that can not only play music but also imitate human voice, was later called Zhuihu.
