The erhu, also called nanhu, and sometimes known in the West as the 'Chinese violin' or 'Chinese two-string fiddle,' is a two-stringed bowed musical instrument, used as a solo instrument as well as in small ensembles and large orchestras. The Bai or Baip are one of the 56 ethnic groups officially recognized by the People's Republic of China. Bai people live mostly in the provinces of Yunnan (Dali area), and in neighboring Guizhou (Bijie area) and Hunan (Sangzhi area) provinces. Dali is the ancient capital of both the Bai kingdom Nanzhao, which flourished in the area during the 8th and 9th centuries, and the Kingdom of Dali, which reigned from 937-1253. Situated in a once significantly Muslim part of South China, Dali was also the center of the Panthay Rebellion against the reigning imperial Qing Dynasty from 1856-1863.
