The tuhu (, pinyin: tÃÂhú) is a Chinese bowed string instrument in the huqin family of instruments. It is used primarily by non-Han ethnic groups of southern China, particularly the Zhuang, who live in the Guangxi province and use it in their bayin (å «é³, lit. "eight sounds") ensemble. It is also used in Yunnan, most prominently in Funing County, Wenshan Zhuang and Miao Autonomous Prefecture.
The instrument's sound box is made from a bottle gourd, which is covered on the playing end with snake skin. The instrument has two strings that are tuned to the interval of a fifth. It is held vertically and produces a lower pitched sound than the maguhu, another southern Chinese fiddle with which it is sometimes played.
