The zhuihu 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 musical 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 referred to as zhuizi, which originated in the Henan province of China. A more modern version of the zhuihu called the leiqin was developed in China in the 20th century.

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.
