The Yi Sanhu (pinyin: yí zú sān hú) is a bow-drawn stringed musical instrument of the Axi and Sani branches of the Yi nationality. The Axi people call it Lehu, and the Sani people call it Lihu and Ehu. In Yi language, "le", "li" and "e" are all meanings of pulling. Shaped like a Zhonghu, the timbre is soft and rich, and it can be used for solo, instrumental ensemble, or to accompany folk songs and dances. It is popular in Lunan Yi Autonomous County, Maitreya, Luxi and Yiliang in Yunnan Province.

The shape is similar to that of Zhonghu, but the body is larger. It is composed of the piano barrel, the headstock, the piano rod, the peg, the jin, the bridge, the strings and the bow. The shape of the Yi Sanhu is similar to the Jinghu in the Han area, but the body of the violin is relatively long.

When playing, the left hand supports the piano bar at a thousand pounds, the thumb hooks the string, and the piano barrel is placed on the left waist, and the left index finger, middle finger, ring finger and little finger are used to press the strings. The right-hand bow is sandwiched between the three strings to play. No matter whether the inner or outer strings are played, the middle strings are sounded at the same time, forming a natural harmony.

Famous pieces include "Yingchun Tune" and "Happy Tune".
