Guangdong Province. Since the conventional instrumental music of Guangdong music in the early stage included two-stringed instruments, fiddles, three-stringed instruments, yueqin, and horizontal flute, it was commonly known as the "five-string instrument" or "hard-bow combination." Pipa or dulcimer were mostly used for solos. After the 1920s, Gaohu was used as the main instrument, supplemented by Yangqin and Qinqin, commonly known as "three-piece head", also known as "soft bow". The main 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.
