Description: The gehu (革胡; pinyin: géhú) is a Chinese instrument developed in the 20th century by the Chinese musician Yang Yusen (杨 雨 森, 1926–1980). It is a hybrid of the Chinese Huqin family and cello. Its four strings are also tuned the same as the cello C G D A. Unlike most of the bowed instruments in the huqin family. Bridge does not come into contact with the snakeskin which faces the other side.

A contrabass version of the gehu also exists; it functions as a double bass. Known as the diyingehu, digehu, or beigehu (倍 革 胡). By the late 20th century the gehu had become a rare instrument, even within China. There is a tendency for the snakeskin to lose its tightness increases with humidity.
