Zuihu (Quhu) (pinyin: zhuì hú) is a Chinese rubbing stringed musical instrument. Also known as Quhu and Erxian. Mainly spread in Henan and Shandong, it is the main accompaniment instrument of Henan Quju Opera, Shandong Qinshu and Lu Opera. The predecessor of Zuihu was Xiaosanxian. When accompanying rap and opera, the artist felt that the effect of plucking the instrument was difficult to match with the singing, so he imitated the huqin, switched to playing with a ponytail bow, and changed the drum to the barrel of the huqin, forming a huqin.
