The folk music of Guangdong is called Soft Bow Three Arrows, which uses Gaohu as the main instrument, supplemented by Yangqin and Qinqin. After the 1920s, Gaohu was used as the main instrument, supplemented by Yangqin and Qinqin, commonly known as three-piece heads and soft bows. The main or characteristic instrument is Gaohu, also known as Yuehu and Nanhu. It is basically the same shape as the erhu, except that the barrel is thinner and shorter.
